Species
Fish and Wildlife Service,
Interior.
ACTION: Final rule.
AGENCY:
We, the U.S. Fish and
Wildlife Service (Service), are listing the
military macaw (Ara militaris) and the
great green macaw (Ara ambiguus) as
endangered under the Endangered
Species Act of 1973, as amended (ESA).
These species are both endemic to
Central and South America. Despite
conservation efforts, these species’
populations are in decline, primarily
due to habitat loss, fragmentation, and
degradation; small population size;
poaching; and regulatory mechanisms
that are inadequate to ameliorate these
threats throughout their ranges.
DATES: This rule becomes effective
November 2, 2015.
ADDRESSES: This final rule is available
on the Internet at https://
www.regulations.gov and comments and
materials received, as well as supporting
documentation used in the preparation
of this rule, will be available for public
inspection, by appointment, during
normal business hours at: U.S. Fish and
Wildlife Service; 5275 Leesburg Pike,
Falls Church, VA 22041.

SUMMARY:
Executive Summary
asabaliauskas on DSK5VPTVN1PROD with RULES
I. Purpose of the Regulatory Action
On January 31, 2008, the Service
received a petition dated January 29,
2008, from Friends of Animals,
represented by the Environmental Law
Clinic, University of Denver, Sturm
College of Law, requesting that we list
14 parrot species under the Endangered
Species Act of 1973, as amended (ESA
or Act; 16 U.S.C. 1531 et seq.). As part
of a court-approved settlement

agreement, the Service agreed to submit
a determination as to whether the
petitioned action is warranted, not
warranted, or warranted but precluded
by other listing actions for the military
macaw (Ara militaris) and the great
green macaw (Ara ambiguus) to the
Federal Register by June 30, 2012. On
July 6, 2012, the Service published a
proposed rule (77 FR 40172) to add the
military macaw and great green macaw
as endangered species to the Federal
List of Endangered and Threatened
Wildlife. This final rule completes the
listing process for these species.
II. Summary of the Major Provisions of
the Regulatory Action
We are listing the military macaw
(Ara militaris) and the great green
macaw (Ara ambiguus) as endangered
species under the Act. We are finalizing
this action primarily because of the
effects of poaching, habitat loss,
fragmentation, and degradation on their
populations; their small and declining
population sizes; and inadequate
regulatory mechanisms to ameliorate the
threats to the species throughout their
ranges.
In this final rule, we used public
comments and peer review to inform
our final determination, as required
under the Act. When we published the
proposed rule on July 6, 2012 (77 FR
40172), we opened a 60-day comment
period on the proposed listing for these
species. During the comment period, we
sought comments from independent
specialists (peer reviewers) on the
specific assumptions and conclusions in
our listing proposal to ensure that the
designation of these species as
endangered is based on scientifically
sound data, assumptions, and analyses.
In addition, we sought comments from
interested parties and the public. We
considered all comments and
information received during the
comment period. In this final rule, we
present and respond to peer reviewer
and public comments. This rule
finalizes the protections proposed for
these two foreign bird species as
endangered species, following careful
consideration of all comments we
received during the public comment
period.
III. Costs and Benefits
Section 4(b)(1)(A) of the ESA directs
that determinations as to whether any
species is an endangered or threatened
species must be made ‘‘solely on the
basis of the best scientific and
commercial data available.’’ Further,
this action is not a ‘‘significant’’
regulatory action under Executive Order
PO 00000
Frm 00002
Fmt 4701
Sfmt 4700
12866. Therefore, we have not analyzed
its costs or benefits.
Background
Section 4(b)(3)(B) of the ESA (16
U.S.C. 1531 et seq.) requires that, for
any petition to revise the Federal Lists
of Endangered and Threatened Wildlife
and Plants that contains substantial
scientific or commercial information
that listing the species may be
warranted, we make a finding within 12
months of the date of receipt of the
petition (‘‘12-month finding’’). In this
finding, we determine whether the
petitioned action is: (a) Not warranted,
(b) warranted, or (c) warranted, but
immediate proposal of a regulation
implementing the petitioned action is
precluded by other pending proposals to
determine whether species are
endangered or threatened, and
expeditious progress is being made to
add or remove qualified species from
the Federal Lists of Endangered and
Threatened Wildlife and Plants. Section
4(b)(3)(C) of the ESA requires that we
treat a petition for which the requested
action is found to be warranted but
precluded as though resubmitted on the
date of such finding, that is, requiring a
subsequent finding to be made within
12 months. We must publish these 12month findings in the Federal Register.
In this document, we announce that
listing these two species as endangered
species is warranted, and we are adding
these two species to the Federal List of
Endangered and Threatened Wildlife in
title 50 of the Code of Federal
Regulations.
Petition History
On January 31, 2008, the Service
received a petition dated January 29,
2008, from Friends of Animals, as
represented by the Environmental Law
Clinic, University of Denver, Sturm
College of Law, requesting that we list
14 parrot species under the ESA. The
petition clearly identified itself as a
petition and included the requisite
information required in the Code of
Federal Regulations (50 CFR 424.14(a)).
On July 14, 2009 (74 FR 33957), we
published a 90-day finding in which we
determined that the petition presented
substantial scientific and commercial
information to indicate that listing may
be warranted for 12 of the 14 parrot
species.
In our 90-day finding on this petition,
we announced the initiation of a status
review to list as endangered or
threatened under the ESA the following
12 parrot species: Blue-headed macaw
(Primolius couloni), crimson shining
parrot (Prosopeia splendens), great
green macaw (Ara ambiguus), grey-

cheeked parakeet (Brotogeris
pyrrhoptera), hyancith macaw
(Anodorhynchus hyacinthinus), military
macaw (Ara militaris), Philippine
cockatoo (Cacatua haematuropygia),
red-crowned parrot (Amazona
viridigenalis), scarlet macaw (Ara
macao), white cockatoo (Cacatua alba),
yellow-billed parrot (Amazona collaria),
and yellow-crested cockatoo (Cacatua
sulphurea). We initiated the status
review to determine if listing each of the
12 species is warranted, and initiated a
60-day public comment period to allow
all interested parties an opportunity to
provide information on the status of
these 12 species of parrots. The public
comment period closed on September
14, 2009.
On July 21, 2010, a settlement
agreement was approved by the Court
(CV–10–357, D. DC), in which the
Service agreed to submit to the Federal
Register by July 29, 2011, September 30,
2011, and November 30, 2011,
determinations whether the petitioned
action is warranted, not warranted, or
warranted but precluded by other listing
actions for no less than 4 of the
petitioned species on each date.
On August 9, 2011, the Service
published in the Federal Register a 12month status review finding for the
crimson shining parrot (a finding that
listing was not warranted) and a
proposed rule for the following three
parrot species: Philippine cockatoo,
white cockatoo, and yellow-crested
cockatoo (76 FR 49202).
On October 6, 2011, we published a
12-month status review finding for the
red-crowned parrot (76 FR 62016); on
October 11, 2011, we published a 12month status review and proposed rule
for the yellow-billed parrot (76 FR
62740); and on October 12, 2011, we
published a 12-month status review for
the blue-headed macaw and greycheeked parakeet (76 FR 63480).
On September 16, 2011, an extension
to the settlement agreement was
approved by the Court (CV–10–357, D.
DC), in which the Service agreed to
submit a determination for the
remaining four petitioned species to the
Federal Register by June 30, 2012.
On July 6, 2012, the Service published
in the Federal Register a 12-month
status review finding and proposed rule
for the four following parrot species:
Great green macaw and the military
macaw (77 FR 40172), hyacinth macaw
(77 FR 39965), and the scarlet macaw
(77 FR 40222).
Upon publication in the Federal
Register on July 6, 2012, of the 12month status review finding and
proposed rule for these species (77 FR
40172), we initiated a 60-day public
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
comment period, which ended on
September 4, 2012. Following
publication of the proposed rule, we
implemented the Service’s peer review
process and during the 60-day comment
period, solicited scientific and
commercial information on the species
from all interested parties.
Previous Federal Actions
In our proposed rule, published July
6, 2012 (77 FR 40172), we announced
that listing the military macaw and the
great green macaw as endangered was
warranted, and we issued a proposed
rule to add these two species to the
Federal List of Endangered and
Threatened Wildlife. The comment
period ended on September 4, 2012; we
received 59 comments from the public.
In response to requests received
during the public comment period, we
reopened another public comment
period on February 21, 2013, which
ended on April 22, 2013 (78 FR 12011).
During the second comment period (see
https://www.regulations.gov, docket
number FWS–R9–ES–2011–0101), we
received 25 more comments on these
two macaw species and on the hyacinth
macaw; however, only one submission
provided substantive information. All
comments, including names and
addresses of commenters, have become
part of the administrative record and are
available at https://www.regulations.gov,
docket numbers FWS–R9–ES–2011–
0101 and FWS–R9–ES–2012–0013.
Summary of Comments and
Recommendations
We base this finding on a review of
the best scientific and commercial
information available, including all
information received during the public
comment period. In the September 4,
2012, proposed rule, we requested that
all interested parties submit information
that might contribute to development of
a final rule. On February 21, 2013, we
reopened the public comment period
where we again requested that all
interested parties submit information
that might contribute to development of
a final rule. We also contacted
appropriate scientific experts and
organizations and invited them to
comment on the proposed listings. We
received comments from four
individuals; one of which was from a
peer reviewer.
Peer Reviewer Comments
(1) Comment: One peer reviewer
provided information on military
macaw population surveys confirming
the presence of 100 macaws in the
Tehuacan-Cuicatlan Biosphere Reserve
in Mexico.

Our Response: We have reviewed the
additional literature and incorporated
the new information into our finding.
Although the new information has been
incorporated into the final rule, the new
survey provided did not change our
finding that the military macaw meets
the definition of an endangered species.
The species’ overall population remains
small and fragmented despite additional
macaws being observed in this one
location, and the species is still at risk
of extinction due to habitat loss,
poaching, and small population size.
Public Comments
(2) Comment: Several commenters
expressed concerns about the potential
impact the listings might have on their
business.
Our Response: We acknowledge that
there may be impacts to different
entities involved in captive breeding of
great green and military macaws.
However, Section 4(b)(1)(A) requires
listing decisions to be based solely on
the best scientific and commercial data
available, as it relates to the five listing
factors in section 4(a)(1) of the Act.
Therefore, the Service did not consider
the impacts on business in its listing
determination.
(3) Comment: Some commenters
suggest that the Service is using
outdated information when making the
determination for the rule.
Our Response: The Service is required
by the Act to make determinations
solely on the basis of the best scientific
and commercial data available. We
based the proposed rule on all the
information we received following the
initiation of the 12-month status review
for the military and great green macaw,
as well as all of the information we
found while conducting our own
research. The information we use
depends on field research and our
ability to acquire that information. At
the time of the publishing of the
proposed rule, the information we
compiled was considered the best
available information. After publishing
the proposed rule, emerging information
on the great green and military macaw
became available. We reviewed that
information, as well as additional
information submitted by the public,
including more recent information and
studies from a species expert and
conservation organizations within the
great green and military macaw’s range
countries. Non-English literature was
professionally translated, analyzed, and
is cited in this document. The
information we received and
subsequently reviewed did not change
any of our findings, but rather further
supported our conclusions. That

Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
information has been incorporated into
this final rule.
(4) Comment: Some commenters,
while not opposed to the listing of the
species, asked for a special rule under
section 4(d) of the Act (also called a
‘‘4(d) rule’’) that would allow ownership
and interstate trade of the species to
occur without obtaining a permit under
the Act.
Our response: Ownership of a listed
species is not prohibited by the Act and,
therefore, does not require a permit.
Because we determined that listing the
great green and military macaws as
endangered species under the Act is
appropriate, we are not able to develop
a 4(d) rule for this species. Section 4(d)
of the Act allows the Service to develop
a special rule to apply the prohibitions
of section 9 or to provide measures that
are necessary and advisable to provide
for the conservation of threatened
species only. A special rule cannot be
promulgated for a species that is listed
as endangered under the Act. The sale;
offer for sale; and delivery, receipt,
carrying, transport, or shipment in
interstate or foreign commerce in the
course of a commercial activity is
prohibited. That said, not all interstate
trade is prohibited under the ESA.
Interstate transfer of animals that are not
for sale, offered for sale, or in the course
of a commercial activity is not
prohibited.
We thank all the commenters for their
interest in the conservation of this
species and thank those commenters
who provided information for our
consideration in making this listing
determination. Under section 4(b) of the
Act, the Service is required to make
listing determinations solely on the
basis of the best scientific and
commercial data available after
conducting a review of the status of the
species. When we published our
proposed rule, we opened a public
comment period during which we
requested any additional information on
the great green and military macaw. In
making this listing determination, we
reviewed the best available scientific
and commercial information, contacted
species experts, and searched for the
most current information on these
species with due diligence. Therefore,
we have obtained and considered the
‘‘best scientific and commercial data
available’’ in our listing determination.
After careful consideration, we
conclude that these species meet the
definition of an endangered species
under the Act.

Species Information for the Military
Macaw
Taxonomy
The military macaw (Ara militaris,
Linnaeus 1766) is in the Psittacidae
family and is also known as ‘‘guacamaya
verde,’’ ‘‘parava,’’ and ‘‘ravine parrot.’’
Three subspecies of military macaw
have been proposed and are recognized
by some: Ara militaris bolivianus
(Reichenow 1908), Ara militaris
mexicanus (Ridgway 1915), and Ara
militaris militaris (Linnaeus 1766).
Avibase, a database of all birds of the
world maintained by Bird Studies
Canada, and the Integrated Taxonomic
Information System (ITIS) both
recognize subspecies (https://
www.itis.gov and https://avibase.bsceoc.org/avibase.jsp, accessed August 30,
2011). The range of A. m. bolivianus is
thought to be in Bolivia and
northwestern Argentina. The range of A.
m. mexicanus is thought to be restricted
to Mexico.
Because it is a strong flyer (it has been
observed traveling up to 20 kilometers
(km) (12 miles [mi]) per day) and it is
a semi-migratory species, the physical
similarities suggest that seemingly
isolated populations may be in contact
(Juniper and Parr 1998, p. 423), and,
therefore, their populations may be
exchanging genetic material.
For the purpose of this rule, we are
addressing the military macaw at the
species level. Therefore, we are listing
the military macaw species as an
endangered species, which includes all
subspecies.
Description
The military macaw is an extremely
vocal species; it is described as being
very noisy and is known to shriek
(Birdlife International (BLI) 2011, p. 1).
It is a large macaw (70 centimeters or
27.5 inches in length) and is vibrant in
color. It has dark lime-green feathers
mixed with blue flight feathers that are
olive-colored underneath. Its forehead is
red, and it has a bare white facial area
and a black bill. Its lower back is blue;
its tail is red and blue. The
southernmost population in Bolivia,
which extends into Argentina, exhibits
reddish brown on their throats and
cheeks (Juniper and Parr 1998, p. 423).
This species is often confused with the
great green macaw (Ara ambiguus). The
great green macaw is very similar in
appearance to the military macaw, but
the military macaw has more prominent
blue tinge on its hind neck, is smaller,
and has darker plumage. These two
species are separated geographically.

Habitat and Life History
Military macaws nest in tree cavities
and cliffs. Cliff-nesting parrots, such as
the military macaw, also nest colonially
(in groups) (Bonilla-Ruz et al. 2007a, pp.
730–731). Cliff cavities located in
ravines used by this species have been
documented 25 and 30 meters (m) (82
to 98 feet (ft)) above ground (ArcosTorres and Solano-Ugalde 2008, p. 71).
Tree cavities used by this species have
been observed to be 18 m (60 ft) above
ground and are approximately 75 cm
(29.5 inches) deep (Baker 1958, p. 98).
This species has also been observed to
use secondary cavities, such as
abandoned woodpecker holes,
particularly in dead pine trees (Strewe
and Navarro 2004, p. 50). Military
macaws alternate nesting and foraging
areas based on food availability
(Bonilla-Ruz 2006, p. 1). Nesting
appears to be synchronous with the
peak fruiting season, which occurs
during April and May (Huatatoca pers.
comm. in Arcos-Torres and SolanoUgalde 2008, p. 70). The military macaw
is a social species that congregates in
small flocks and is often observed in
mated pairs. Its clutch size is usually
two to three eggs. They begin
reproducing between 3 and 4 years of
age (Mexican National Commission for
Protected Areas [CONANP] 2006 in
Bonilla-Ruz 2006, p. 2). Colonial nesting
is believed to be due to the lack of
suitable disbursed nest sites, which may
also explain why they are concentrated
in certain sites (Salinas-Melgoza et al.
2009, p. 306).
This species prefers the lower
montane wet forests of the Andes. It
inhabits remaining fragmented forested
area in the Neotropics. However, in the
northernmost part of its range, in
Mexico, it is associated with seasonally
dry, semi-deciduous tropical forest,
deciduous tropical forest, and slopes of
pine-oak forest (Bonilla-Ruz et al.
2007b, pp. 45–47; Rivera-Ortiz et al.
2006, p. 26).
The military macaw is a seasonal
migrant, based on food and nutrient
availability. In some areas, it has been
observed at clay licks to obtain sodium
and possibly other minerals, which is a
common activity in some parrot species
(Lee 2010, p. 58). Its diet varies
seasonally. Some of the plant species it
was observed feeding on include
(Rivera-Ortiz et al. 2013, p. 1211; Carillo
et al. 2013, p. 46; Huellega 2011, p. 9;

Seeds were found to be 39 percent of
this species’ diet. They have also been
observed feeding on bromeliad stems
(species unknown) and cacti (species
unknown). In the northern part of its
range in Mexico, military macaws have
been observed in desert habitat,
although they tend to have lower
reproductive success in this habitat type
(Rivera-Ortiz et al. 2008, p. 261). In
desert habitat, which is suboptimal, it
has been observed consuming some
flowers (species unidentified). Despite
the low seasonal abundance of food,
deserts offer some refuge from poaching
due to the inhospitable dry climate,
which can act as a deterrent to poachers
(Rivera-Ortiz et al. 2008, p. 261). In
addition, macaws tend to nest at very
high locations, which can make it
difficult for poachers to reach them.
Range, Observations, and Population
Estimates
The military macaw is distributed in
highly fragmented, small populations in
Mexico and South America, with a
distribution gap in Central America (BLI
PO 00000
Frm 00005
Fmt 4701
Sfmt 4725
2014a, pp. 1–2; Rivera-Ortiz 2013, p.
1,201; Juarez et al 2012, pp. 6–7). Its
range extends from northern Mexico
southward into Ecuador, Peru,
Colombia, Venezuela, Bolivia, and the
southern tip of Argentina (see Figure 1
for an approximation of its range and
distribution). The species has been
described as patchily distributed
throughout the eastern foothills of the
Andes Mountains (Snyder et al. 2000, p.
125). It occurs in altitudes up to 1,600
m (5,249 ft) (Strewe and Navarro 2004,
p. 50; Snyder et al. 2000, pp. 102, 124–
125). Although it has a large distribution
(276,000 km2 (106,564 mi2)), its
populations are localized.
Its population is estimated to be
6,667–13,333 mature individuals (BLI
2014, pp. 1–2; Rivera-Ortiz et al. 2013,
p. 1,201). Most areas where this species
occurs are now estimated to have fewer
than 100 individuals. However, in 2004,
other populations in Colombia and
Mexico were estimated to be 100–200
´
individuals (Florez and Sierra 2004, p.
3). This species may have occurred in
Guatemala in the past, but it is no longer
found there (Gardner 1972 in Snyder et
al. 2000, p. 125). Overall, its
populations are fragmented and
becoming more isolated (Rivera-Ortiz
2008, p. 256).

Argentina
Argentina is the southernmost part of
this species’ range, and the species was
never thought to have been abundant
there (Navarro et al. 2008, p. 1). In fact,
this species was initially thought to be
extirpated (locally extinct) in Argentina,
but surveys have found small
populations in at least two locations in
the northern province of Salta (Grilli et
al 2013, p. 235; Juarez et al 2012, pp. 7–
8). There are anecdotal reports of this
´
species crossing the Itau River (Navarro
et al. 2008, p. 3), which borders Bolivia
and Argentina. Between 2005 and 2007,
approximately 100 individuals were
observed in the Salta Province. These
areas include: Finca Itaguazuti, and the
Acambuco Provincial Flora and Fauna
Reserve (8,266 hectares [ha] or 20,426
acres [ac]) in the Tartagal Mountains
and which borders Bolivia (BLI 2014;
Navarro et al. 2008, pp. 1, 4; Coconier
et al. 2007, p. 59). In 2008, flocks of
between 4 and 40 individuals of this
species were observed in three ravines
in the Salta Province. These locations
were the Agua Fresca (Cool Water)
Ravine north of Campo Cauzuti, El
´
Limon Ravine (which had the largest
´
population), and the Caraparı River
Ravine. These are believed to be
established populations, rather than
flocks crossing over from Bolivia
(Navarro et al. 2008, pp. 1, 4).
Andean foothills in Bolivia in forested
areas extending from the northern
Tambopata National Reserve to the
´
southern Pilon Lajas Reserve
(Hennessey et al. 2003, pp. 319, 329).
These parks are in the general vicinity
of the border of southern Peru and
northern Bolivia (Hosner et al. 2009, p.
222; Navarro et al. 2008, p. 2; Hennessey
et al. 2003, p. 322). They are part of the
Greater Madidi-Tambopata Landscape
(GMTL) (also known as ‘‘Parque
Nacional Madidi’’). Within the GMTL,
there are thought to be reasonably
healthy populations of this species in
the Apolobamba National Integrated
´
Management Area, Amboro and Madidi
´
National Parks, and Pilon Lajas
Biosphere Reserve (Hennessey 2011
pers. comm.; Hosner et al. 2009, p. 225).
The Greater Madidi-Tambopata
Landscape is 110,074 km2 (42,500 mi2)
in size, and encompasses one of the
largest areas of intact montane forest in
the tropical Andes (WCS 2009, p. 2).
This area is a high conservation priority
due to its large number of endemic bird
´
species. Pilon Lajas consists of primary
evergreen tropical lowland forest,
foothill forest, and lower montane
´
forest. Pilon Lajas was recognized as a
Biosphere Reserve and Indigenous
Territory by the Bolivian Government in
1992; however, it did not have any
actual protections in place until 1994
(Hennessey et al. 2003, p. 319).
In 2008, this species was observed at
´
Serranıa Sadiri in Madidi National Park,
La Paz Department, Bolivia (Hosner et
´
al. 2009, p. 225). Serranıa Sadiri is
found just inside Madidi National Park.
Here, flocks of between 2 and 36
individuals have been observed (Hosner
´
et al. 2009, p. 228). The Pilon Lajas
Biosphere Reserve is primarily in La Paz
Department, but slightly overlaps into
the Beni Department. Here, this species
is described as uncommon (Hennessey
2003, p. 329). It was observed in
Parapetiguasu-Taremakua, and
Parapetiguas-Uruwigua in Santa Cruz,
Cordillera Province, and at Altamachi
and Madidi in Cochabamba, Ayopaya
Province (MacLeod 2009, pp. 42–43). In
summary, within Bolivia, there are
many small populations of this species
in areas that provide suitable habitat for
this species (primarily large forest
patches under some form of protection).
Bolivia
In Bolivia, the military macaw is
regularly observed in five national
parks: Tambopata National Reserve,
´
Pilon Lajas Biosphere Reserve, Madidi
National Park, Apolobamba National
Integrated Management Area, and
´
Amboro National Park (Hennessey 2011,

In the late 1990s, there were
approximately five disjunct populations
in the central Andes Mountains (Snyder

of 50 individuals have been observed,
and in one case, a population was
estimated to have 156 individuals

The species inhabits tropical, semideciduous forests along the Pacific and
Atlantic slopes through Central and
South America. The best available

most cases, these individuals reside on
cliff formations that are favorable for
nesting (where they are less accessible
to poachers), and where deforestation is
´
having less of an impact (Florez and
Sierra 2004, pp. 2–3; Rodriguez and
´
Hernandez-Camacho 2002, p. 203). In
Colombia, this species inhabits a wide
range of altitudes and areas with various
´
degrees of alteration (Florez and Sierra
2004, pp. 1–3; Juniper and Parr 1998).
In Colombia, this species has been
observed between altitudes of 700 and
´
1,600 m (2,297 to 5,249 ft) (Florez and
Sierra 2004, pp. 1–3; Salaman et al.
2002, pp. 167, 187). Populations have
been observed in Guajira peninsula, Las
Orquideas, Tayrona National Park,

´
´
Serranıa de Perija, Serranıa de San
Lucas, San Salvador Valley, Sierra
Nevada De Santa Marta, La Guajira
Department, and Cueva de los
Guacharos National Park (Strewe and
Navarro 2003, p. 3). In 1998, this species
was observed in flocks of up to 12
individuals at Villa Iguana and Alto
´
Cagadero in Serranıa de los
Churumbelos (Salaman et al. 2007, pp.
33, 38, 47, 89). It has been observed in
palm stands in the San Salvador valley
during the breeding season (December–
July) (Strewe and Navarro 2003, p. 33).
There are two small, stable
populations of military macaws at Sierra
Nevada de Santa Marta and
Churumbelos, Cauca, with
approximately 50 mature birds at each
´
site (Fundacion ProAves 2011, p. 28). In
´
2004, Florez and Sierra estimated that
the population in the cliffs of the Cauca
River was 156 individuals and
contained 54 breeding pairs and 26
nests (2004, p. 3). However, this
population is subjected to impacts from
´
poaching and deforestation (Florez and
Sierra, 2004, pp. 3–4), so the population
now may be smaller. These researchers
also noted that many chicks fall from
the cliff nests and die. As of 2011, there
were no recent records in northern
´
Antioquia (Paramillo), Serranıa de San
´
´
Lucas, or Perija ranges (Fundacion
ProAves 2011, pp. 28–29).
´
In the Frıo Valley of Colombia, this
species is reported to be present only
during the breeding season (Strewe and
Navarro 2004, p. 50). Several nests were
found here in forest fragments. A
population at El Congo Reserve was
intensively studied in 2001. One nest
was located 12 m (39 ft) above ground
in a Ceiba tree, within open primary
forest on a steep slope at 900 m (2,953
ft). A breeding population of 12 pairs,
with groups of up to 28 was observed
in December 2000. However, here it is
still threatened in the valley by habitat
loss and domestic trade (two cases
noted in 2001) (Strewe and Navarro

200 ha (494 ac) were turned into the
Narupa Reserve, where this species was
observed in approximately 2010

Jalisco
This species is found sporadically in
small groups of a few to approximately
100 macaws in the western foothills of
Sierra del Cuale and Sierra Cacoma in
Jalisco on the western coast of Mexico
(Renton 2004, pp. 13–14). Other groups
of macaws in the region are in Cabo
Corrientes in the Horcones river basin
(approximately 100 macaws). There are
other small populations in the vicinity
of Puerto Vallarta (Carrillo et al. 2013,
pp. 45, 47). This species was observed
´
in 2004 near a freshwater lake, Cajon de
˜
Pena (26 by 9 km (16 by 5.6 mi) in size),
which was constructed in 1976. It is
found in the Chamela-Cuixmala
Biosphere Reserve (132,000 ha or 32,617
ac), which is managed by Mexico’s
Instituto de Ecologia of the National
Autonomous University of Mexico
(UNAM) and nongovernmental
organizations (NGOs). Patches of semideciduous forest in this area form
corridors between existing protected
areas, such as the Chamela-Cuixmala
´
and the Sierra Manatlan Biosphere
Reserves (Renton 2004, p. 14). These
patches likely have served as critical
ecological links for this species.

Oaxaca
This species has recently been the
focus of research in Sabino Canyon,
Oaxaca. Sabino Canyon is in the
Tehuacan-Cuicatlan Biosphere Reserve
(Reserva de la Biosfera Tehuacan
Cuicatlan), created in 1998, in central
Mexico. The reserve spans 490,187 ha
(1,211,278 ac) and is located within the
˜
Mixteca Oaxaquena Province between
´
the cities of Puebla and Orızaba. It is
approximately 150 km (93 mi) southeast
of Mexico City (https://
www.parkswatch.org, accessed July 11,
2011) and approximately 2 hours from
Tehuacan, Oaxaca, Mexico. Large
mountain ranges delineate the
boundaries of the reserve, and six rivers
are within the protected area’s
boundaries.
In 2001, this species was observed in
two canyons within this reserve. In both
ravines, 20 pairs were observed nesting
(Salazar-Torres 2001, p. 18). Here, this
species nests in the canyon cliff walls in
crevices that can be as high as 250 m
(820 ft). Between 2002 and 2004,
approximately 100 individual military

macaws were observed (Bonilla-Ruz et
al. 2007a, p. 729). During 2007–2008, at
least 67 birds were observed during the
month of August (Rivera-Ortiz et al.
2008, p. 256; Rivera-Ortiz et al. 2006, p.
26). The known nesting site locations
within the reserve increased from five to
nine during the study period (RiveraOrtiz et al. 2006, p. 28). Currently in the
Sabino Canyon, the population of
military macaws is thought to be
between 90 and 100 individuals
(Arizmendi 2008, p. 15).
Sinaloa
This species exists in Mineral de
˜
Nuestra Senora de la Candelaria
Ecological Preserve, 12 km (7.4 mi)
southeast of the town of Cosala in
Sinaloa, Mexico (Rubio et al. 2007, p.
52; Bonilla-Ruz et al. 2007b, p. 45). The
preserve is 1,256 ha (3,104 ac) and
consists of dry tropical forest. In 2002,
this area was designated as a protected
area by the State of Sinaloa Decree.
Sonora
Between 2008 and 2009, it was
observed at the Northern Jaguar Reserve
in east-central Sonora, and was
described as a rare summer resident
there (Flesch 2009, pp. 5, 12). In this
area, this species was recently observed
in small flocks in cliff areas (Flesch
2008, pp. 35–36). In 2005, it was
´
observed in the Rıo Aros canyon and
´
upper Rıo Yaqui valley in an area
known as the Yaqui Basin (O’Brien et al.
2006, pp. 4, 27–28). Flesch suggests that
the species is likely to occur only in
cliffs near stands of tropical vegetation
(full citation 2008, p. 27).
Tamaulipas
Historically, in Mexico’s eastern State
of Tamaulipas, flocks of approximately
60 individuals were noted almost daily
´
´
in the area of Gomez Farıas, Mexico
(Sutton and Pettingill 1942, p. 14). The
´
´
Gomez Farıas region is on the eastern
slope of the Sierra Madre Oriental
mountain range, known locally as the
‘‘Sierra de Guatemala.’’ This area is in
the general vicinity of the stateprotected El Cielo Biosphere Reserve,
where this species is still known to
occur (Arvin 2001, p. 8). The University
of Texas at Brownsville maintains a
research station, Rancho del Cielo,
within the 145,687-hectare (360,000acre) reserve. The research station
supports locally driven scientific
research and community development
(University of Texas at Brownsville,
unpaginated). Activities conducted by
the research station have positive
impacts on this species by attracting

Peru
There are populations in Manu
Biosphere Reserve, Tambopata National
Reserve, and Bahuaja Sonene National
Park in Peru. The two latter parks
border one another in the southern
Peruvian Amazon region (ParksWatch
2002, p. 1). This species has been
observed around the Pongo de Mainique
of the Urubamba River and on the upper
Tambopata River (Snyder et al. 2000, p.
125). According to a 2010 paper, it was
observed in the Madre de Dios
department in the southeastern
Peruvian Amazon (Lee 2010, p. 14).
Flocks of 40 to 50 individuals have been
observed in Atalya at Madre de Dios
(Snyder et al. 2000, p. 125). The species
has been observed seasonally in small
´
numbers in the area of the Huallaga
River Canyon (JGP Consultants 2011 pp.
1, 5, 8).
Venezuela
Within Venezuela, it has been
documented primarily within protected
areas. In this country, little information
about the species exists (Rodriguez et al.
2004, pp. 375–376). Here it persists in
the Andes in the Central Coastal
´
Cordillera and Sierra de Perija
(Rodriguez et al. 2004, pp. 375, 378,
379). It has been found on the north
´
slopes of El Avila, Guatopo, Henri
Pittier National Park, the State of
´
Cojedes, Cerro La Mision, and Sierra de
´
Perija National Park (Desenne and
Strahl 1994 and Fernandez-Badillo et al.
1994 in Snyder et al. 2000, p. 125). A
new population of this species was
recorded at two localities at the
´
Catatumbo-Barı National Park along the
Colombian-Venezuelan border
˜
(Avendano 2011, p. 2). Moist forests
exist as four distinct enclaves within the
Catatumbo Valley, in both northwestern
Venezuela and northeastern Colombia.
This extends the species’ previously
known range from the east slope of the
´
´
Serranıa de Perija southwards
˜
(Avendano 2011, p. 2).
Summary of Range
According to several surveys, the
military macaw exists in small
populations ranging from a few pairs to
approximately 100 individuals. It is
found in protected areas in Mexico,
Colombia, Bolivia, and to a lesser
extent, in Ecuador, Peru, Venezuela, and
Argentina (see Figure 1), and is unlikely
to exist in small populations outside of
protected areas where large expanses of
suitable habitat still remain (Bonilla
´
2012, p. 9). The population in the Pilon
Lajas Biosphere Reserve, Bolivia, may
E:\FR\FM\02OCR3.SGM
02OCR3
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
serve as a link to other populations of
this species to the northwest and to the
south (Hennessey et al. 2003, pp. 330–
331). Records indicate that this species
occurs primarily in protected areas
(Flesch 2009; MacLeod 2009; Flesch
´
2008; Florez and Sierra 2004; Rodriguez
2004; Renton 2004; Hennessey et al.
2003), such as protected parks where
there are large remaining areas of
suitable habitat for nesting, feeding, and
breeding (see Figure 1).
Summary of Population Estimate
There are various but imprecise
population estimates for the military
macaw. One report estimates the
population to be fewer than 10,000
individuals (Arizmendi 2008, p. 3). BLI
reports that the population is estimated
to be between 10,000 and 19,999 mature
individuals with a decreasing trend (BLI
2014, p. 2). We believe that the
population is significantly fewer than
10,000 based on recent documented
observations of this species, most of
which are described in this status
review. Researchers in Colombia agree
with our conclusion (Botero–Delgadillo
´
and Paez 2011, p. 13). Published
literature (referenced in this document)
has documented small flocks ranging
from approximately 16 to 156
individuals distributed in disjunct
locations in Mexico, Argentina,
Ecuador, Venezuela, Peru, Colombia,
and Bolivia. In situations where the
species is rare or has small populations,
the number of observations made per
survey may be very small and the
number of sites limited, and, therefore,
estimates may not be accurate (Pollack
2006, p. 891).
The current total population number
is unclear; however, based on these
recent records, we believe that the
population is between a few thousand
and 10,000 remaining individuals (BLI
2014, p. 1; Bonilla 2012, p. 9).

Conservation Status
International Union for Conservation of
Nature (IUCN)
There are various protections in place
for this species at the international,
national, and local levels. At the
international level, this species is listed
as vulnerable by the IUCN (2011).
However, this status under IUCN
conveys no actual protections to the
species.
CITES
The military macaw is protected by
the Convention on International Trade
in Endangered Species of Wild Fauna
and Flora (CITES), which is one of the
most important means of controlling
international trade in animal and plant
VerDate Sep<11>2014

species affected by trade. CITES is an
international agreement through which
member countries, called Parties, work
together to ensure that international
trade in CITES-listed animals and plants
is not detrimental to the survival of wild
populations by regulating their import,
export, and reexport. All of the range
countries for this species are Parties to
CITES (https://www.cites.org/eng/disc/
parties/alphabet.php, accessed May 7,
2014). Most psittacines (parrots),
including the military macaw, were
included in CITES Appendix II in 1981.
An Appendix-II listing includes species
not necessarily threatened with
extinction, but in which trade must be
controlled in order to avoid utilization
incompatible with their survival. The
military macaw was transferred to
Appendix I of CITES in 1987, because
populations were declining rapidly due
to uncontrolled trapping for the
international pet bird trade. An
Appendix-I listing includes species
threatened with extinction whose trade
is permitted only under exceptional
circumstances, which generally
precludes commercial trade.
WBCA
The import of the military macaw into
the United States is also regulated by
the Wild Bird Conservation Act (WBCA)
(16 U.S.C. 4901 et seq.), which was
enacted on October 23, 1992, in an effort
to ensure that exotic bird species are not
adversely affected by U.S. trade. The
purpose of the WBCA is to promote the
conservation of CITES-listed exotic
birds by ensuring that all imports into
the United States are (1) sustainable and
(2) not detrimental to the species.
Permits may be issued to allow imports
of listed birds for scientific research,
zoological breeding or display, or as
personal pets when certain criteria are
met. The Service may approve
cooperative breeding programs and
subsequently issue import permits
under such programs. Wild-caught birds
may be imported into the United States
if the Service approves a management
plan for their sustainable use. At this
time, the military macaw is not part of
a Service-approved cooperative
breeding program and does not have an
approved management plan for wildcaught birds.
Argentina
This species is considered to be a
critically endangered species by the
Government of Argentina (Navarro et al.

Conservation of Fauna, enacted in 1981.
Decree 691/81 addresses the protection
and conservation of wild fauna and is
implemented through law 22.421.
Bolivia
In Bolivia, this species is listed as
vulnerable. The 1975 Law on Wildlife,
National Parks, Hunting and Fishing
(Decree Law No. 12,301 1975, pp. 1–34)
has the fundamental objective of
protecting the country’s natural
resources. This law governs the
protection, management, utilization,
transportation, and selling of wildlife
and their products. It also governs the
protection of endangered species,
habitat conservation of fauna and flora,
and the declaration of national parks,
biological reserves, refuges, and wildlife
sanctuaries.
Colombia
Colombia categorizes this species as
‘‘vulnerable’’ (Salaman et al. 2009, p.
21). A vulnerable species is considered
to be one that is not in imminent danger
of extinction in the near future, but it
could be if natural population trends
continue downward and deterioration of
its range continues (EcoLex 2002, p. 10).
Ecuador
In Ecuador, this species is considered
´
endangered, ‘‘en peligro de extincion’’.
Here, this species is considered to be
very rare (Arcos-Torres and SolanoUgalde 2008, p. 69).
Mexico
In Mexico, the military macaw is
protected as endangered under Mexico’s
Wildlife Protection Act (Benetiz-Diaz
2012, p. 2) and has been highlighted as
a priority species for conservation in the
Mexican Parrot Conservation Plan
(Rivera-Ortiz et al. 2008, p. 256; Renton
2004, p. 12). Its official list of
endangered and threatened bird species
is termed the Norma Oficial Mexicana
059 (NOM–059, 2010) (Benetiz-Diaz
2012, p. 2).
Peru
In Peru, this species is listed as
vulnerable and its protections fall under
the jurisdiction of the National Institute
of Natural Resources (Instituto Nacional
de Recursos Naturales, INRENA). Peru’s
Supreme Decree No. 034–2004–AG
(2004, p. 276,855) prohibits hunting,
take, transport, and trade of protected
species, except as permitted by
regulation.
Venezuela
In Venezuela, this species is listed as
endangered (Rodriguez et al. 2004, p.
376).

NGO Involvement
In the 1980s, conservationists realized
the value of identifying areas or habitat
in terms of numbers of endemic bird
species. BirdLife International, in
partnership with countries, other
nongovernmental organizations (NGOs),
and various other partners, developed
the Important Bird Area (IBA) program,
which is a worldwide initiative to
identify and protect critical areas for
bird conservation. IBAs are areas that
regularly contain significant numbers of
one or more globally threatened species
or other species of global conservation
concern. One of the criteria in
identifying important regions for bird
conservation is the distribution of
restricted-range and globally threatened
species such as the military macaw. As
of 2007, more than 8,500 IBAs had been
´
identified worldwide (Garcıa-Moreno et
al. 2007, p. 324). The military macaw is
included in 37 of those IBAs (BLI 2011b,
pers. comm.). Note that this does not
mean this species always occupies those
areas; rather, the species has been
identified in those areas.
A number of locally based and
international conservation organizations
have developed programs in connection
with protected areas within this species’
range, such as ecotourism, to observe
clay lick areas (Lee 2010, pp. 167–168).
The Wildlife Conservation Society
(WCS) is implementing a range of
projects aimed at strengthening the
management of Greater MadidiTambopata Landscape in Bolivia. Its
program is based on three main
categories: (1) Park management, (2)
natural resources management, and (3)
scientific research (Parks Watch 2005,
pp. 2–3). The Greater MadidiTambopata Landscape, where the WCS
is monitoring populations of the
military macaw (WCS 2009, pp. 2, 8),
encompasses one of the largest swaths
of intact montane forest in the Tropical
Andes in northern Bolivia and southern
Peru. The GMTL is 110,074 km2 (42,500
mi2) and includes five protected areas.
´
A Colombian-based NGO, Fundacion
ProAves, is also working to protect this
´
species and its habitats. Fundacion
ProAves developed a conservation plan
for 2010 to 2020 for several parrot
species, including the military macaw
´
(Botero-Delgadillo and Paez 2011, p. 7).
However, it is unclear if or when it will
be adopted by the Government of
Colombia.
In Mexico, several NGOs are
participating in the conservation and
management of this species. In 1989, a
strong citizen movement began to
conserve the 383,567-ha (947,815-ac)
Sierra Gorda Biosphere Reserve by

establishing the local group, Grupo
´
Ecologico Sierra Gorda. In collaboration
with the local community, this group
has taken action to protect bird
communities as well as other groups of
wildlife in this area. Strategies include
environmental education, establishment
of private reserves, and payment for
environmental services in a 25,000-ha
(61,776-ac) area of this reserve (PedrazaRuiz, 2008 p. 1). The Chamela-Cuixmala
Biosphere Reserve is managed by
Mexico’s Instituto de Ecologia of the
National Autonomous University of
Mexico (UNAM) and local NGOs. Other
NGOs are working with communities to
obtain macaw feathers from aviaries so
that indigenous people will not hunt the
macaws for their feathers (Renton 2004,
p. 14). In the Sinaloa area, the
´
Universidad Autonoma de Sinaloa has
been active in conservation of this
species since 1998 (Rubio et al. 2007, p.
52). This university conducts research
outreach activities to foster knowledge,
and conservation of this species at the
˜
Mineral de Nuestra Senora de la
Candelaria Ecological Preserve.
Evaluation of Threat Factors
Introduction
Section 4 of the ESA (16 U.S.C. 1533)
and implementing regulations (50 CFR
424) set forth procedures for adding
species to, removing species from, or
reclassifying species on the Federal
Lists of Endangered and Threatened
Wildlife and Plants. Under section
4(a)(1) of the ESA, a species may be
determined to be endangered or
threatened based on any of the
following five factors:
A. The present or threatened
destruction, modification, or
curtailment of its habitat or range;
B. Overutilization for commercial,
recreational, scientific, or educational
purposes;
C. Disease or predation;
D. The inadequacy of existing regulatory
mechanisms; and
E. Other natural or manmade factors
affecting its continued existence.
Throughout the range of this species,
the factors impacting this species are
generally very similar. The primary
factors affecting the military macaw are
habitat loss and degradation, and
poaching (Carrillo et al. 2013, p. 46;
˜
Gastanaga et al. 2011, entire; Strewe and
Navarro 2004, p. 50). Habitat loss is
primarily due to conversion of the
species’ habitat (generally forests) to
agriculture and other forms that are not
optimal for the military macaw (Donald
´
et al. 2010, p. 26; Florez and Sierra
2004, p. 3). Conversion of habitat to soy
plantations is now considered to be one
PO 00000
Frm 00010
Fmt 4701
Sfmt 4700
of the principal causes of Amazon
deforestation (Bonilha 2008, p. 17).
Because this species has a small and
fragmented population, poaching, while
apparently uncommon, remains a
´
concern (Botero-Delgadillo and Paez
2011, p. 13).
We focus primarily on where this
species has been documented,
particularly in parks and other areas
with protected status and the peripheral
zones. In some cases, we will evaluate
the factor by country. In other cases, we
may evaluate the factor by a broader
region if we do not have adequate
information specific to a particular
country about this species. This is
because often the threats are the same or
very similar throughout the species’
range.
A. The Present or Threatened
Destruction, Modification, or
Curtailment of Its Habitat or Range
Habitat
The military macaw has a large but
fragmented distribution (276,000 km2
(106,564 mi2)), and not all locations
where the military macaw exists are
known (BLI 2014, p. 1). Habitat
destruction and modification is one of
the main threats to the military macaw;
significant amounts of this species’
habitat have been converted such that
its habitat is no longer suitable and no
longer provides adequate shelter
(nesting sites) and food sources, and
these causes of habitat loss are likely to
continue (Marin-Togo et al. 2012, p.
462). Between 2000 and 2005, of all the
continents, South America had the
largest net loss of forested area,
experiencing a loss of 4.3 million ha
(10.6 million ac) per year (FAO 2006 in
Mosandl et al. 2008, p. 38). In some
countries, extractive activities for
nontimber forest products occur, such
as the removal of palm trees (Arecaceae
family) to obtain hearts of palm
(ParksWatch 2011; https://
www.tropicalforestresearch.org).
Currently, the military macaw exists
in many parks and other areas that have
´
protected status (Marın-Togo et al. 2012,
p. 465; Coconier et al. 2009, p. 63;
Arizmendi 2008, p. 4; Rodriguez et al.
2004, p. 78; Renton 2004, p. 12). Studies
have found that, compared with the
surrounding areas, conditions inside
parks were significantly better than their
surrounding counterparts (Bruner et al.
2001, p. 125). One study found that, in
40 percent of tropical parks, land that
had formerly been under cultivation and
that was incorporated into park
boundaries had recovered. This
subsequently led to an increase in
vegetative cover. The study found that

asabaliauskas on DSK5VPTVN1PROD with RULES
83 percent of parks were successful at
mitigating encroachment (Bruner et al.
2001, p. 125). This was confirmed in a
study published in 2007 that found that
forests in conservation units were four
times better at protecting against
deforestation than unprotected areas
(Oliveira et al. 2007, p. 1,235). However,
this species still faces habitat loss
(Benetiz 2012, p. 4).
We are limiting our analysis to areas
where there is information available
about this species. For instance, there is
very little information available about
this species in Argentina and Venezuela
(Coconier et al. 2009, p. 63; Navarro et
al. 2008, p. 1; Coconier et al. 2007, p.
52; Rodriguez et al. 2004, pp. 378–379).
However, in both of these countries, the
species faces similar threats (such as the
lack of suitable habitat) as in other
countries (Rodriguez et al. 2004, p. 373).
The largest populations of this species,
discussed in detail in the Range,
Observations, and Population Estimates
section, appear to be in Mexico and
Bolivia. Even in these countries, its
populations are small and fragmented.
In other countries within its range such
as Colombia, Peru, and Ecuador, it
exists in smaller populations, and
Argentina (Nores and Yzurieta 1994, pp.
315–316) and Venezuela have even
smaller and possibly negligible
populations. Additionally, the military
macaw may have occurred in Guatemala
in the past, but it is no longer found
there (Gardner 1972 in Snyder et al.
2000, p. 125).
Argentina
In Argentina, habitat destruction,
particularly deforestation for
agricultural expansion for soy
plantations, and timber extraction had
significantly increased as of 2009
(Devenish 2009, p. 60; Chebez et al. in
litt. in Navarro et al. 2008, pp. 7, 9;
DiPaola et al. 2008, pp. 1, 8). The
species was thought to no longer exist
in Argentina, which is the southernmost
part of its range, but recent surveys
found small populations of this species
in at least two locations in the Salta
Province (Navarro et al. 2008, p. 1). The
primary threat to forested areas in
Argentina is the expansion of
agriculture, particularly soy, into
remaining habitat such as the Chaco
plains in the Andes mountain range
´
(Centro de Accion Popular Olga
´
´
Marquez de Aredez (CAPOMA) 2009, p.
6). The practice of drying swamps
through channeling is common in
northern Argentina, particularly for
producing soybeans, which is
experiencing increasing demand in the
global market. The current rate of
deforestation stands at 25,000 ha
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
(61,776 ac) per year resulting from land
converted to agricultural use (Devenish
2009, p. 60). The area converted to soy
production increased from as little as 3
percent in the 1970s to 40 percent of the
total crop area in 2003, covering 14
million ha (34.6 million ac) (Devenish
2009, p. 60). Conversion of lands to soy
production is favored by the current
political and economic climate, both at
the global and national levels (Devenish
2009, p. 60). With regard to other types
of land use, the area used for cattle
ranching has decreased, but exotic tree
plantations have doubled (Devenish
2009, p. 60).
In addition, pipeline routes and
associated roads are being established in
this area in connection with oil, gas, and
mineral exploration (Navarro et al. 2008,
pp. 7, 9). Road building operations
greatly facilitate access to large,
previously inaccessible forested areas
(Fimbel et al. 2001, pp. 511–512). The
area occupied by permanent facilities
including pipelines and refineries is
relatively small, but oil development
areas cover large tracts of land. Oil
development can have significant
negative impacts on nearby habitat
through construction of roads and other
buildings, discharge of contaminants,
and oil spills and leaks (Gay et al
undated, pp. 2–6).
Although some of this species’ habitat
is protected, its habitat continues to
shrink in Argentina. In the area of
Acambuco, where the military macaw
has been observed, the designation of
Acambuco Reserve as a provincial
reserve provides some protective
measures. The purposes of this reserve,
in part, are to preserve its genetic
resources, to preserve the environment
surrounding catch basins of its rivers,
and to guarantee the maintenance of the
biodiversity living in the reserve.
However, in the Salta Province, this
species is primarily found in areas that
are unprotected, with the exception of
the Acambuco Reserve (Navarro et al.
2008, pp. 1, 7, 9). In summary,
significant amounts of this species’
habitat have been converted such that
its habitat is no longer suitable, and
these causes of habitat loss are likely to
continue.
Bolivia
Madidi National Park experiences
threats that are representative of threats
to this species’ habitat in Bolivia. The
park is one of the key areas where this
species likely has a viable population in
Bolivia. Thus, we focused our analysis
on this park. The National Service of
Protected Areas (SERNAP) has authority
over Bolivia’s parks and protected
lands. Approximately 53 percent (57.2
PO 00000
Frm 00011
Fmt 4701
Sfmt 4700
59985
million ha; 141.3 million ac) of Bolivia’s
total area is forested (FAO 2010, p. 228).
Of this area, 38.9 million ha (96.1
million ac) are within the Bolivian
Amazon and constitute 5 percent of the
total Amazon forest (Locklin and Haack
2003, p. 774). As of 2005, Bolivia had
12 national parks, including 6 with
integrated management natural areas, 1
with indigenous territory (or communal
lands), and 4 national reserves; 2
biosphere reserves; and 3 integrated
management natural areas, totaling
16,834,380 ha (41,598,659 ac)
(ParksWatch 2005, p. 2). A discussion of
typical threats in Bolivia’s parks
follows. The region suffers from chronic
and intense poverty levels, which affect
more than 90 percent of the population
´
(Instituto Nacional de Estadıstica de
Bolivia (INE) 2005). The result is intense
conflict between development and
conservation. In Madidi National Park,
the three greatest threats to the nature
preserve are the construction of a
highway within the park, drilling for oil,
and a planned hydroelectric dam. Other
activities that are impacting or are likely
to impact this park are illegal logging,
gold mining, and uncontrolled tourism
(ParksWatch 2011b, pp. 1–15; Chavez
2010, pp. 1–2).
Deforestation and Logging
The forests of Bolivia have mainly
been subjected to selective logging (Salo
and Toivonen 2009, p. 610;
Fredericksen 2003, p. 10), which has
been done at very low levels and with
low human pressures (Pacheco 2006, p.
206), allowing them so far to remain
largely intact. In the five national parks
where the military macaw is regularly
observed, there are some protections in
place for the species’ habitat (Hennessey
2011, pers. comm.). However, logging
still occurs within the range of this
species (ParksWatch 2011b, p. 1). Large
tracts of primary forest remain in
Bolivia, but it is likely that some of
these will be subjected to logging
(Fredericksen 2003, p. 13) due to slashand-burn activities by indigenous
communities, and because forest
products are one of Bolivia’s primary
exports (Byers and Israel 2008, p. vi).
The use of slash-and-burn practices on
steep and erodible slopes has
considerably affected the area’s
hydrological regime, particularly near
the city of Santa Cruz. In many areas of
human settlement, soil erosion is
compounded by logging, nutrient
depletion, and weed invasion.
As of 2006, 89 timber companies held
the rights to 5.8 million ha (14.3 million
ac) of logging concessions (Pacheco
2006, p. 208). The Bolivian Forestry
Law of 1996 (Forestry Law 1700)
E:\FR\FM\02OCR3.SGM

59986
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
asabaliauskas on DSK5VPTVN1PROD with RULES
requires the preparation and approval of
management plans and adherence to
best management practices (BMPs)
(Fredericksen 2003, p. 10). For instance,
harvesters must pre-map harvestable
trees (which have minimum diameter
limits), protect seed trees, and set aside
areas that are designated as protected or
not harvestable. Management issues still
need to be addressed, including
sufficient regeneration time for
commercial species (Fredericksen 2003,
p. 10). However, Bolivia continues to
attempt to balance the use of its natural
resources with competing priorities. For
´
example, the Pilon Lajas Management
Plan divided the reserve into specific
zones to combine indigenous
community rights with conservation
initiatives (Hennessey et al. 2003, p.
320). Despite national laws and
regulations, activities such as illegal
timber extraction continue to spread
unabated (World Bank 2006, p. 8; U.S.
Forest Service 2007, p. 2; Pacheco 2006,
p. 208).
Roads
There are increasing demands for road
infrastructure within Bolivia for many
reasons. It is one of the poorest
countries in South America (MacLeod
2009, p. 6; INE 2005), and the
government would like to improve its
economy (ParksWatch 2011b, p. 13).
The construction of the Apolo-Ixiamas
Road is one way of facilitating access to
its natural resources. A road has been
proposed that would bisect the Madidi
National Park and Natural Integrated
Management Area, opening vast,
currently inaccessible tropical forest
areas to colonization and resource
extraction (ParksWatch 2011b, pp. 1–2).
This can promote illegal logging, and
facilitate access to previously
inaccessible forested areas (Fimbel et al.
2001, pp. 511–512). The construction of
roads through this park has been a
source of controversy for several years
https://conservation-strategy.org/sites/
default/files/field-file/6_Madidi_Road_
Complete_Document.PDF, accessed May
6, 2014). The current status of the road
and whether it will be constructed
around the park or through the park
remains unclear. However, regional
development plans are often
implemented without consideration of
impacts on natural resources (WCS
2009, p. 4). Plans to connect Bolivia and
Peru to Brazil’s expanding markets and
expand the energy industry (oil and gas)
will affect fragile areas of high
biodiversity (WCS 2009, p. 4). Roads
constructed in the past have also been
problematic. In the late 1990s, roads
´
through Serranıa Sadiri spurred an
increase in unsustainable logging of the
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
area’s mahogany trees, which were the
most valuable tree at the time (World
Land Trust 2010, p. 1).
Hydroelectric Power
Possibly one of the greatest threats in
the Madidi National Park is the
proposed Bala Hydroelectric Dam
Project at the Beni River in the Bala
Gorge, where the Beni River goes
through the Bala Mountain Range. The
Bala Hydroelectric Dam, as proposed,
could flood much of Madidi National
Park and the adjacent biosphere reserve
´
and indigenous territory Pilon Lajas,
which is an area of about 2,000 km2
(4,942 mi2) (Chavez 2010, pp. 1–2;
Bolivia Supreme Decree 24191).
Construction of dams can have severe
impacts on ecosystems (McCartney et al.
2001, p. v). For example, a dam blocks
the flow of sediment downstream.
During construction of dams,
disturbance to soils at the construction
site is one of the largest concerns. This
leads to downstream erosion and
increased sediment buildup in a
reservoir. Although the current status of
this dam is unclear, it is clear that the
Government of Bolivia is intent on
becoming more self-reliant, in part
through creating its own sources of
energy through hydroelectric dams.
Other Pressures
In Madidi National Park, there is
limited legal hunting, but in the areas
surveyed, this species was described as
common and not exploited (Hosner et
al. 2009, p. 226). Nine villages or
communities are within the national
park, and 22 are in the integrated
management natural area. Of the 31
communities, 3 are located in the
Andean plateau zone. In the lowlands,
two of the communities occupy the zone
of valleys around the municipality of
Apolo. Timber extraction occurs here
(WorldLand Trust 2010, p. 1). In 2010,
an additional 25,090 ha (62,000 ac) of
pristine tropical rainforest in Bolivia
were protected, following a decision by
an indigenous community to create a
tourism refuge in the Sadiri rainforest
(WorldLand Trust 2010, p. 6). Landless
Andean farmers make a living in the
lowlands, and they at times expand the
agricultural frontier, increasing the risk
of disease transmission between
domestic animals and wildlife, bringing
crops and domestic animals closer to
wildlife predators, and increasing
hunting pressure in surrounding forests
(WCS 2009, p. 4).
In summary, threats to the species’
habitat in Bolivia include unsustainable
land use practices, illegal logging, road
building, and exploration activities for
oil extraction, which are contributing to
PO 00000
Frm 00012
Fmt 4701
Sfmt 4700
the erosion of Bolivia’s ecosystems
(MacLeod 2009, p. 6; ParksWatch 2005,
p. 1). Large tracts of primary forest
remain in Bolivia, but it is likely that
many of these will be subjected to
logging and other pressures, such as
extraction of non-timber forest products,
particularly because forest products
contribute to Bolivia’s national exports
(Byers and Israel 2008, p. vi). The
Government of Bolivia is attempting to
balance improving its economy with
conservation initiatives, and some of its
development initiatives may negatively
impact this species’ habitat. Despite
protections in place, this species’
habitat in Bolivia continues to
experience these threats, and we expect
these pressures to continue into the
future.
Colombia
In the past, human colonization,
development, and exploration within
the range of the species in Colombia
were limited due to the exceptionally
steep and high terrain of the Andes
(Salaman et al. 2002, p. 160). However,
researchers reported in 2004 that the
Cauca River Canyon in northeastern
Colombia, an area containing military
macaws, was extensively deforested
´
(Florez and Sierra 2004, p. 3). The main
threats in the lowlands are the
expansion of agriculture, particularly by
small farmers in the middle altitude
areas, and extractive activities such as
hunting (including the removal of birds
to sell as pets) and wood harvesting
(Salaman et al. 2007, p. 89). As
resources become scarcer in the
lowlands, these pressures move upland.
Associated with these farming practices
is the use of livestock and the erosion
caused by livestock grazing on steep
slopes, as well as erosion due to
cultivation.
A 2010 report indicated that forest
cover was largely continuous in
Colombia, but deforestation had
increased dramatically as of 2010 (FAO
2010, pp. 22, 106). Deforestation rates in
lowland moist forest on the foothills of
the eastern Andes of Colombia are
rapidly accelerating. Deforestation has
increased from 1.4 percent (1961–1979)
to 4.4 percent (1979–1988), and is
correlated with increasing human
population density (Salaman et al. 2007,
˜
p. 89; Vina and Cavelier 1999, p. 31).
Primary forest habitats throughout
Colombia have undergone extensive
˜
deforestation. Vina et al. (2004, pp. 123–
124) used satellite imagery to analyze
deforestation rates and patterns along
the Colombian-Ecuadorian border (in
the Departments of Putumayo and
Sucumbios, respectively), finding that
between 1973 and 1996, a total of 829

km2 (320 mi2) of tropical forests within
the study area were converted to other
uses. This corresponds to a nearly onethird total loss of primary forest habitat,
or a nearly 2 percent mean annual rate
of deforestation within the study area.
Since the 1970s, the Colombian
Government has encouraged road
construction and colonization projects.
The goal is to create links to the vast
and undeveloped Amazonian region,
and to open up the Llanos and
Amazonian lowlands for utilization of
their natural resources (Salaman et al.
2007, pp. 10, 89; Salaman et al. 2002, p.
160). In recent years, this species’
habitat has come under increased
pressure with the completion of the
´
Mocoa-Bogota highway, the proposed
´
Puerto Asıs-Florencia road, and the
discovery and exploitation of petroleum
and precious metals. All of these factors
contribute to an escalation in human
encroachment and associated impacts
that degrade this species’ habitat
(Salaman et al. 2007, p. 10). The few
remaining forest connections between
the upper and lower slopes are under
pressure, even where they are
minimally protected.
Five main routes link the lowlands
from Colombia’s high Andean interior to
other areas. Infrastructure development
on the eastern slope of the Andes in
Colombia, as well as adjacent Ecuador,
has also caused significant human
population pressures and has led to
much habitat degradation. Increased
and improved access roads have led to
the conversion of mature tropical forests
for pasture lands, petroleum products
exploitation, and coca plantations
(Salaman et al. 2007, p. 89). These road
projects to link Colombia with
Venezuela and Ecuador along the entire
eastern base of the Andes have
contributed to additional deforestation.
´
Serranıa de los Churumbelos National
Park
´
Currently, the Serranıa de los
Churumbelos forest is almost entirely
intact and is owned by the government
(Salaman et al. 2007, pp. 10, 91–92).
This mountain range has largely
avoided the degree of human impact
that other regions have suffered.
However, this is changing rapidly due to
mineral exploration (petroleum and
precious metals) and natural resources
(timber and rich organic soils for
´
agriculture) demands. The Serranıa de
los Churumbelos could become the
focus of large-scale deforestation and
colonization in the near future (Salaman
et al. 2007, p. 89). Parque Natural
´
Nacional Cueva de los Guacharos

in this region although it is a small park

(approximately 5,000 ha or 12,355 ac),
and even here, illegal encroachment
occurs (Salaman et al. 2007, p. 89).
´
Catatumbo-Barı National Park
The primary threat in the Catatumbo´
Barı National Park (at the ColombianVenezuelan border) is deforestation and
impacts associated with coca
plantations surrounding the Park
´
(Fundacion ProAves 2011, pp. 28–29).
Coca cultivation has fluctuated for
several years. Over a 4-year study
period, it contained about 100 ha (247
ac) of coca (United Nations Office on
Drugs and Crime, undated report, p. 33).
A new population of this species was
recently recorded at two locations in
˜
this park (Avendano 2011 in BLI 2014a,
p. 2). In addition, one population in the
Cauca valley (fewer than 50 mature
birds) could be affected by the
construction of a dam (155 m (508.5 ft)
in height) that could affect its sole
breeding cliff. However, the status of the
dam is still unclear (American Bird
Conservancy 2012, p. 24).
Ecuador
Ecuador experiences one of the
highest deforestation rates in South
America (Mosandl et al. 2008, p. 37).
Forested habitat within many parts of
Ecuador has diminished rapidly due to
logging, clearing for agriculture, and
road development (Youth 2009, pp. 1–
3; Mosandl et al. 2008, p. 37; Sierra
1999, p. 136; Dodson and Gentry 1991,
pp. 283–293). Between the years 1990
and 2005, Ecuador lost a total of 2.96
million ha (7.31 million ac) of primary
forest, which represents a 16.7 percent
deforestation rate, and a total loss of
21.5 percent of forested habitat since
1990 (Butler 2006b, pp. 1–3; FAO
2003b, p. 1). Much of the primary moist
forest habitat has been replaced with
pastures and scattered trees (Collar et al.
1992, p. 533). Very little suitable habitat
now remains for the species here, and
remaining suitable habitat is highly
fragmented (Bass et al. 2010, p. 2;
Snyder et al. 2000, p. 122). In the area
where this species exists, near the Gran
Sumaco Biosphere Reserve, there are
several oil reserves (Celi-Sangurima
2005, p. 22). However, specific impacts
to this species as a result of oil
exploration or extraction activities are
unknown.
The colony in Kichwa River Reserve
is currently in an area designated as
protected, although it is unclear what
these protections entail. In this area, the
local community group Macaw Rio is
interested in conducting ecotourism.
Although this colony has persisted for
about 150 years (Huatatoca pers comm.
in Arcos-Torres and Solano-Ugalde
PO 00000
Frm 00013

2008, p. 72), it likely will be affected by
logging and the resulting deforestation
on nearby land. Researchers suggest that
the apparent lack of this species in
Ecuador is possibly related to lack of
suitable sites for the formation of
breeding colonies, or lack of knowledge
about sites that may be located in
inaccessible areas (Arcos-Torres and
Solano-Ugalde 2008, p. 72). We know of
no specific threats to the species in the
Kichwa River Reserve, other than those
associated with small population sizes,
which is discussed under Small
Population Size, below.
Mexico
Mexico has suffered extensive
deforestation (conversion of forest to
other land uses) and forest degradation
(reduction in forest biomass through
selective cutting, etc.) over the past
several decades (Commission for
Environmental Cooperation (CEC) 2010,
pp. 45, 75). In recent decades, Mexico’s
deforestation has been rapid (Blaser et
al. 2011, pp. 343–344). Between 1990
and 2000, Mexico lost forest (factoring
in natural regeneration of degraded
forest and planting of forest in areas that
previously did not have forest) at a net
rate of 344,000 ha (850,043 ac) per year
(FAO 2010, p. 21). During 1990–2010,
Mexico lost approximately 6 million ha
(15 million ac) of forest, and had one of
the largest decreases in primary forests
worldwide (FAO 2010, pp. 56, 233).
Although Mexico’s rate of forest loss has
slowed in the past decade, it still
continues. The current rate of net forest
loss in Mexico is 155,000 ha (383,013
ac) per year, with an estimated 250,000–
300,000 ha (617,763–741,316 ac) per
year degraded (Government of Mexico
(GOM) 2010b, in Blaser et al. 2011, p.
344; FAO 2010, p. 233).
As of 2010, Mexico had 64.8 million
ha (160.1 million ac) of forest (Food and
Agriculture Organization (FAO) 2010, p.
228), and 50 percent of these forests are
considered degraded. Projections of lost
forested area by the year 2030 in Mexico
are between 10 percent to nearly 60
percent of mature forests lost, and
approximately 0 to 54 percent of
regrowth forests lost (CEC 2010, pp. 45,
75). Deforestation via forest conversion
to agricultural uses remains a major
driver of land transformation in Mexico
(CEC 2008, p. 24). Agricultural
production is projected to double within
the country by 2030 (CEC 2010, pp. 34,
70). Although some of this increase in
production is expected due to an
increase in productivity on previously
converted land, total agricultural land
area in Mexico is projected to increase
by 6,300 to 41,400 ha (15,568 to 102,302
ac) by 2030 (CEC 2010, p. 75).

In the range of the military macaw,
such as the tropical forest along the
Pacific coast of Mexico, high rates of
deforestation have occurred; slash-andburn agriculture still occurs along with
grazing. In 2002, it was estimated that
the species had suffered a 23 percent
habitat loss within its range in Mexico
using a Genetic Algorithm for Rule-set
´
Prediction (GARP) analysis tool (Rıos˜
Munoz 2002, pp. 24, 32). GARP analysis
essentially uses ecological
characteristics of known species
locations in order to determine its likely
distribution.
A 3-year study documented loss of
habitat, particularly trees used by
macaws, in the Tehuacan-Cuicatlan
Biosphere Reserve, Sabino Canyon. In
their study, researchers found a total of
170 individual plants of species
consumed by military macaws in the
pine forests in an area of 1,500 m2
(16,146 ft2) in 2005 (Arizmendi 2008, p.
43). By January 2008, eleven (6.5
percent) of these trees had been logged.
In the transitional forest between dry
and pine (in an area of 1,000 m2 or
10,764 ft2), 134 plants were documented
in 2005, and by January 2008, fifteen
(11.90 percent) of them had been logged.
Arizmendi suggested that these
activities are carried out by local
communities, and suggested that a local
environmental education campaign be
implemented. A reduced number of
trees limit the availability of adequate
food resources across the landscape.
With fewer trees remaining, the area
cannot support the same number of
individuals of the species and,
therefore, causes a further reduction in
the population. Macaws were not found
in deforested areas, even where one of
their important food sources, Hura
polyandra, was left as shade for cattle
´
(Rivera-Ortız et al. 2008, p. 256). As
further support, in Jalisco, most of the
sites where macaws were present had
little or no habitat loss (note that none
of the sites in Jalisco where military
macaws were located were in protected
areas). No macaws were located in sites
with more than 30 percent habitat loss,
even though these sites may have had
abundant trees.
Mining
˜
At the Mineral de Nuestra Senora
´
reserve in Cosala, where this species
occurs, mining activities are occurring
(Rubio et al. 2007, p. 52; Bonilla-Ruz et
al. 2007b, p. 45). This reserve is 12 km
´
(7.5 mi) southeast of Cosala in Sinaloa,
Mexico. This reserve was created after a
joint effort in 1999 between the state,
municipal government, and the
Autonomous University of Sinaloa. The
Autonomous University of Sinaloa

conducted technical studies to propose
the area as a nature reserve. The
university also conducted conservation
projects here which focused on the
‘‘Ecology and Conservation of the
Military Macaw’’ and ‘‘Environmental
Education and Ecotourism.’’ In 2002,
˜
the Mineral de Nuestra Senora reserve
was formally designated. Since then,
parrot populations and their habitat
here both within and outside the
preserve have been affected by mining
activities taking place in the area (Rubio
et al. 2007, p. 52). In early 2005, mining
efforts began on underground
development and drilling (Scorpio
Mining 2011, p. 2). The current effect of
mining on the species is unclear.
Peru
There is little to no current published
information with respect to specific
threats to this species in Peru
˜
(Gastanaga et al. 2011, entire; JGP
Consultants 2011, entire; Lee 2010,
entire; Cowen 2009, entire; Terborgh
2004, entire; Brightsmith 2004, entire).
It exists in several parks that convey
some measures of protection (Oliveira et
al. 2007, p. 1,235; Terborgh 2004, p. 35).
Peru’s protected areas are managed by
the General Department of Natural
Protected Areas, INRENA, under the
authority of Law No. 26834, Law of
Natural Protected Areas, promulgated in
1997. The Peruvian national protected
area system includes several categories
of habitat protection. Habitat may be
designated as any of the following:
(1) Parque Nacional (National Park, an
area managed mainly for ecosystem
conservation and recreation);
(2) Santuario (Sanctuary, for the
preservation of sites of notable natural
or historical importance);
(3) Reserva Nacional (National
Reserve, for sustainable extraction of
certain biological resources);
´
(4) Bosque de Proteccion (Protection
Forest, to safeguard soils and forests,
especially for watershed conservation);
(5) Zona Reservada (Reserved Zone,
for temporary protection while further
study is under way to determine their
importance);
(6) Bosque Nacional (National Forest,
to be managed for utilization);
(7) Reserva Comunal (Communal
Reserve, for local area use and
management, with national oversight);
and
(8) Cotos de Caza (Hunting Reserve,
for local use and management, with
national oversight) (BLI 2008, p. 1;
´
Rodrıguez and Young 2000, p. 330).
Because the designations of national
parks, sanctuaries, and protection
forests are established by supreme
decree that supersedes all other legal
PO 00000
Frm 00014

Sfmt 4700
claim to the land, these areas tend to
provide more habitat protection than
other designations. All other protected
areas are established by supreme
resolution, which is viewed as a less
´
powerful form of protection (Rodrıguez
and Young 2000, p. 330).
This species has been documented in
the Tambopata National Reserve, which
is a 275,000-ha (679,540-ac)
conservation area created by the
Peruvian Government in 1990. The
main purpose was to protect the
watersheds of the Tambopata and
Candamo Rivers. This area protects
some of the last pristine lowland and
premontane tropical humid forests in
the Amazon. Within the Tambopata
National Reserve, there have been
isolated human settlements along
stretches of the Malinowski River,
which flows into the Tambopata River.
Fewer than 5,000 people inhabit the
Tambopata National Reserve’s border
area to the north. They make a living of
slash-and-burn agriculture, small-scale
gold mining, timber extraction, and
hunting and fishing. One area of
Tambopata, including a buffer zone, was
recently described as a ‘‘crisis zone’’
(Lee 2010, p. 169). It has been described
as being at high risk for illegal
settlement, timber extraction, and
mining (Lee 2010, p. 169).
Populations of this species are
thought to be in the Manu Biosphere
Reserve and the Bahuaja Sonene
National Park in Peru (WCS 2007, p. 1;
Herzog in litt. 2007; Terborgh 2004, pp.
40–41). The problems here are primarily
due to human population growth
(Terborgh 2004, pp. 40–41). Five
indigenous groups reside in the Manu
Biosphere Reserve—they are both legal
and illegal settlers (Terborgh 2004, pp.
40–41). An ecological research station
´
has been in place since 1973 in Manu
National Park (Terborgh 2004, entire),
which also adds some protection to the
species. Research has shown that often
simply having a long-term research
presence there can help to reduce
poaching (Campbell et al. 2011, p. 2).
Unlike parks in the United States, in
countries such as Peru, parks and
protected areas were formed around the
indigenous tribes that live there
(Terborgh 2004, p. 51), and the
management and purpose of the parks
often include protection of the rights of
indigenous human communities. This
philosophy of park protection and
mandates of parks differs from in the
United States, where humans are
viewed as visitors to the parks, rather
than permanent residents (Terborgh
2004, p. 51). In Manu Biosphere
Reserve, another potential threat is oil
exploration. Both Shell and Mobil Oil
E:\FR\FM\02OCR3.SGM

Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
have conducted oil exploration
activities in this area (Terborgh 2004, p.
55; ParksWatch 2002, pp. 5, 7). Within
Bahuaja, as of 2002, there were no
human establishments within its
boundaries (ParksWatch 2002a, p. 1).
However, activities that could affect the
military macaw in this area include gold
mining, illegal logging, extraction of
forest resources, and farming
(ParksWatch 2002b, p. 1).

Venezuela
There is little published information
about the military macaw in Venezuela
(BLI 2014, pp. 1–2; Rodriguez 2004,
entire). Here it exists in the Andes in the
Central Coastal Cordillera, and Sierra de
´
Perija (Rodriguez et al. 2004, pp. 375,
378, 379). It has been found on the north
´
slopes of El Avila, Guatopo, Henri
Pittier National Park, Ceroo La Mision,
´
and Sierra de Perija National Park
(Desenne and Strahl 1994 in Snyder et
al. 2000, p. 125; Fernandez-Badillo et al.
1994 in Snyder et al. 2000 p. 125). Most
of its range in Venezuela is within
protected areas, but as of 2000, threats
still were reported to exist in the
protected areas (Snyder et al. 2000, p.
125). In 2000, Snyder et al. noted that
´
Sierra de Perija was being deforested for
narcotics, land speculation, and cattle
(p. 125). A population of this species
was recorded for the first time at two
´
localities at the Catatumbo-Barı National
Park in the Colombian-Venezuelan
border, extending the previous species’
´
range from the east slope of the Serranıa
´
˜
de Perija southwards (Avendano 2011,
p. 2).
Summary of Factor A
Habitat loss, human encroachment,
and conversion to agriculture are the
main threats acting on the species
throughout its range. These threats are
exacerbated by an inability by range
country governments to adequately
manage and monitor the species (see
discussion under Factor D, below).
South America had the largest net loss
of forest area of all continents between
2000 and 2005 (Mosandl et al. 2008, p.
38), with a net loss of 4.3 million ha per
year. Although specific, detailed
information about this species’
remaining occupied habitat status is not
available for each country, we know that
much of this species’ habitat has been
lost through conversion of land to
farming, forestry, or other activities
(Bonilha and Switkes 2008, p. 17; Etter
et al. 2006, p. 369; Renton 2004, p. 13).
Conversion of habitat to soy plantations
is now considered to be one of the
principal causes of Amazon
deforestation. Deforestation may already
have destroyed as much as 1.2 million
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
ha (3 million ac) in the Amazon. This,
combined with pressures of capture for
the pet trade, has severely impacted the
wild population of military macaws.
Studies have shown that, over time,
resident bird diversity generally
declines as remaining forest becomes
smaller and more fragmented (Turner
1996, pp. 202, 206).
As with most parrots, the military
macaw requires large areas of suitable
habitat, including large trees or other
nesting cavities for nesting, feeding, and
roosting as well as food sources.
Deforestation and logging is a common
form of habitat loss that affects this
´
species (Benetiz-Diaz 2012, p. 4; Rıos˜
Munoz et al. 2009, pp. 502–505).
Deforestation via conversion of land to
agricultural use is a threat to military
macaws because it directly eliminates
forest habitat, removing the trees that
support the species’ nesting, roosting,
and dietary requirements. It also results
in fragmented habitat that isolates
military macaw populations, potentially
compromising the genetics of these
populations through inbreeding
depression and genetic drift (Lande
´
1995, pp. 787–789; Gilpin and Soule
1986, p. 27). We do not know the exact
extent of deforestation in the range of
the military macaw. However, the best
available information indicates that
deforestation continues to occur and
affect the species throughout its range,
despite protections that are in place.
Currently the population of military
macaws is extremely small (likely a few
thousand individuals), those
populations are severely fragmented,
and its suitable habitat is becoming
increasingly more scarce. Therefore,
based on the best available scientific
and commercial information, we find
that the present or threatened
destruction, modification, or
curtailment of habitat or range is a
threat to the military macaw now and in
the future.
B. Overutilization for Commercial,
Recreational, Scientific, or Educational
Purposes
The trade in wild parrots is common
in some areas of South America
´
˜
(Gastanaga et al. 2011, entire; Cantu–
´
Guzman et al. 2008, entire). In its Red
List assessment, the IUCN indicates that
the two major threats to the military
macaw are habitat loss and capture for
the domestic pet trade (IUCN 2011, p.
1). Many reports indicate that poaching
for the pet trade is still a problem for
parrot species, particularly in poorer
countries (Herrera and Hennessey 2007,
entire; Dickson 2005, p. 548). For
perspective, in the United States,
captive-bred specimens of this species
PO 00000
Frm 00015
Fmt 4701
Sfmt 4700
59989
were recently found offered for sale for
$699 (Basile 2010, p. 2). In 2006, four
military macaws were advertised for
sale with an average sale price of $850
´
´
(Cantu–Guzman et al. 2008, p. 72).
Although the scope of the illegal trade
in the military macaw is unknown,
poaching can be a lucrative and
relatively risk-free source of income
(Dickson 2005, p. 548).
A high percentage of birds die during
the process of capturing from the wild,
transporting, and selling them. Because
most of these activities are illegal, it is
difficult to accurately determine the
actual mortality rate, but estimates vary
between 31 and 90 percent (Weston and
´
´
Memon 2009, p. 79; Cantu-Guzman et
al. 2007, pp. 7, 20, 22, 55, 60). Military
macaws mate for life, are long-lived, and
have low reproductive rates. These traits
make them particularly sensitive to the
impacts of their removal from the wild
(Lee 2010, p. 3; Thiollay 2005, p. 1,121;
Wright et al. 2001, p. 711). Wild harvest
can destroy pair bonds, remove
potentially reproductive adults from the
breeding pool, and have a significant
effect on small populations (Kramer and
Drake 2010, p. 11). These activities
adversely affect a species’ population
numbers (Pain et al. 2006, p. 322).
Although poaching continues to occur
for the pet trade, it has been found to
be significantly lower at protected sites
(Pain et al. 2006, pp. 322–328; Wright et
al. 2002, p. 719). Other reports have
found that national or local protection,
particularly when local communities are
actively involved in conservation
efforts, can successfully reduce nest take
(Pain et al. 2006, p. 328; Chassot et al.
2006, pp. 86–87). Gonzalez (2003, pp.
437–446) found evidence of poaching,
particularly during nesting seasons, in
the Pacaya-Samiria National Reserve, a
protected area in the Loreto Department,
Peru, during his 1996–1999 study.
However, he also found that poaching
decreased during the 1998 harvest
season (Gonzalez 2003, p. 444), which
he attributed to increased numbers of
birds confiscated by regional
authorities, which may have
subsequently discouraged poaching
(also see Factor D, below).
A related factor is the destruction of
trees in this species’ habitat due to
poaching. This species primarily
depends on tree-cavity nests as its
habitat. Not only does nest poaching
negatively affect this species by
reducing the population size and the
number of birds available to reproduce,
it also in some cases destroys this
species’ habitat. Several studies have
found that poachers will cut down trees
to remove nests. A study conducted in
the late 1990s found that in some cases
E:\FR\FM\02OCR3.SGM

asabaliauskas on DSK5VPTVN1PROD with RULES
59990
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
in Peru, poachers cut down the nesting
tree in order to access the nestlings
(Gonzalez 2003, p. 443). They also were
observed ‘‘hacking’’ open the nest
cavities to remove chicks (Bergman
2009, pp. 6–8; Low 2003, pp. 10–11). An
average of 21 nests was destroyed per
poaching trip (Gonzalez 2003, p. 443).
Nest destruction was also reported by
Bergman in Ecuador in 2009 (pp. 6–8).
The military macaw was listed in
CITES Appendix II, effective June 6,
1981, and was transferred to CITES
Appendix I, effective October 22, 1987.
Most of the international trade in
military macaw specimens consists of
live birds. Data obtained from the
United Nations Environment
Programme—World Conservation
Monitoring Center (UNEP–WCMC)
CITES Trade Database show that, during
the nearly 6 1⁄2 years that the military
macaw was listed in Appendix II, a total
of 1,034 military macaw specimens
were reported to UNEP–WCMC as
(gross) exports. Of those 1,034
specimens, 1,019 were live birds and 15
were feathers. In analyzing these data, it
appears that several records may be
over-counts due to slight differences in
the manner in which the importing and
exporting countries reported their trade.
It is likely that the actual number of
military macaw specimens in
international trade during this period
was 973, including 958 live birds and 15
feathers. Fourteen of the live birds were
captive-bred, and the others were
reported with the source unknown.
Exports from range countries included:
364 live birds from Bolivia; 320 from
Mexico; 11 from Ecuador; 4 from
Venezuela; and 1 from Argentina.
During the more than 25 years
following the transfer to Appendix I
(October 22, 1987 through December 31,
2012, the last year for which complete
data were available at the time the
following numbers were compiled, the
UNEP–WCMC database shows a total of
1,894 military macaw specimens as
(gross) exports, including 1,455 live
birds, 224 scientific specimens, 213
feathers, 1 body, and 1 trophy (UNEP–
WCMC trade database, accessed May 20,
2014). As noted above, it appears that
some records may be over-counts due to
differences in the manner in which the
importing and exporting countries
reported their trade. It is likely that the
actual number of live military macaws
in international trade during the 25-year
period was 1,301. Of those 1,301 birds,
1,022 were captive-bred or captive-born,
and 119 were reported as wild. The
source of the remaining live birds is
unknown. Exports from range countries
included: 54 live birds from Mexico; 10
from Argentina; 4 from Venezuela; 2

from Colombia; and 1 from Peru.
Annual quantities exported ranged from
a low of 14 live birds during 2006, to
122 live birds (including 80 exported
from South Africa) in 2009. Since 2004,
none of the exports from range countries
has been reported as wild origin.
Argentina, Bolivia, Ecuador, and
Mexico
In Argentina, Ecuador, and
Venezuela, there is little to no
information available about
overutilization. International trade has
diminished, but local trade continues to
occur. In Bolivia, a report published in
2009 indicated that of 17,609 birds
(including military macaws)
documented in the market studied in
Department of Santa Cruz (not far from
the range of this species), 64 percent of
the birds were found to be adults
captured in the wild. Ninety percent
(24,707) of the birds were found to be
from the Department of Santa Cruz. A
total of 2,604 individuals were from the
Department of Tarija, 176 from the
Department of Beni, 20 from Peru, and
12 from Brazil (Herrera and Hennessey
2009, p. 233). The report indicated that
most parrots (some of which were
military macaws) were locally sold, and
found that 23,306 were in the city of
Santa Cruz, and 4,156 were sent to
Cochabamba.
In Mexico, the military macaw is
reportedly one of the most sought-after
species in the illegal pet bird trade
´
´
(Cantu-Guzman et al. 2007, p. 38), and
poaching remains a concern. In 1995–
2005, it was the fifth most seized
Mexican psittacine species by Mexico’s
Environmental Enforcement Agency,
becoming the fourth most seized
psittacine species in 2007–2010 (p. 52).
As an example, at a sinkhole in El Cielo
Biosphere Reserve, a population of
approximately 50 birds was decimated
´
by poaching in the 1980s (Aragon-Tapia
in litt. 1989 in Snyder et al. 2000, p.
125). In many areas, it nests in relatively
inaccessible cavities on cliff walls,
which provide some protection against
the pressures of nest poaching.
However, nest poaching is a severe
threat in Jalisco and Nayarit, where the
species nests in tree cavities (Contreras´
Gonzalez et al. 2007, p. 43; Renton in
litt. 2007 and Bonilla in litt. 2007 in BLI
2011a, pp. 1–2). Between 2005 and 2006
in Mexico, five military macaws were
found for sale, and the average price
´
´
was $373 (Cantu-Guzman et al. 2007, p.
76).
Local residents in Argentina indicated
that young chicks are removed ‘‘for
foreigners’’ but also noted that it is
extremely difficult due to the difficulty
in accessing the species’ preferred

nesting sites and the aggressiveness of
the macaws (Navarro et al. 2008, pp. 7,
9). Additionally, in Mexico and
Ecuador, indigenous communities have
used military macaw feathers for
ceremonial and medicinal practices.
However, NGOs are working with these
communities to obtain macaw feathers
from aviaries so that the indigenous
people will not hunt the macaws
(Renton 2004, p. 14).
Colombia
This species and other Ara macaws
are occasionally hunted by indigenous
people in Colombia. In one study, in the
´
Catatumbo-Barı National Park, hunting
was found to be concentrated around
the 15 indigenous communities within
the 160,000-ha (395,369-ac) park
˜
(Avendano 2011, p. 2). In 2004, in a
cliff-nesting location along the Cauca
River, Colombia, threats to this species
included poaching and loss of foraging
´
trees (Florez and Sierra 2004, pp. 2–3).
They found that, at the Cauca River site,
it was common for some people to
remove hatchlings from the nests and
sell between 20 to 30 chicks per year on
the black market (p. 3). To counteract
these activities, a local awareness
´
campaign was initiated (Florez and
Sierra 2004, pp. 2–3). As a result of this
project, 3,000 Hura crepitans trees (a
species used by the military macaw)
were planted by the local communities,
and the awareness campaign appeared
to be effective. Researchers do not
believe that hunting pressure is a
serious short-term threat. However,
local education and awareness programs
generally need to be ongoing and longterm for them to be effective, and the
local communities need to be aware of
the benefits of conserving species in the
wild as well as having an alternative
source of income (i.e., income other
than that derived from poaching).
Peru
A recent study in Peru examined nest
poaching and illegal trade of parrots,
including the reasons for poaching, and
the methods, seasons, and locations
where the sale and actual poaching of
parrots occurred. This study found that
this species is still being poached in the
˜
wild (Gastanaga et al. 2011, pp. 79–80),
even in protected areas and despite
national protections in place. During the
2007–2008 study, eight military macaws
were found for sale in two out of eight
markets surveyed in Peru (p. 79). Seven
of these birds were found in the
Amazonian lowland city, Pucallpa (p.
80). The study also found that, where
protections and enforcement have been
implemented such as in Cusco, there
were no parrots for sale in markets. This
E:\FR\FM\02OCR3.SGM
02OCR3
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
indicates that, although it still
continues, poaching is becoming less
frequent due to involvement by NGOs,
minimal international demand for the
species, and enforcement by authorities.
Summary of Factor B
Among birds, parrots are the group
most subject to commercial trade
(Hutton et al. 2000, p. 14). Parrots have
suffered a disproportionate number of
extinctions, in part due to their
desirability as pets. Conservation efforts
by the various entities working to
ensure long-term conservation of the
military macaw may result in its
population slowly increasing; however,
it is likely that the population is still
declining. Even though the military
macaw is listed as an Appendix-I
species under CITES and laws have
been established within the range
countries to protect this species, we are
still concerned about the illegal capture
of this species in the wild. Despite
regulatory mechanisms in place and
restricted international trade, poaching
is lucrative and continues to occur.
Additionally, because each population
of military macaws is small, with
usually fewer than 100 individuals,
poaching is likely to have a significant
effect on the species. Based on the best
available scientific and commercial
information, we find that overutilization
for commercial, recreational, scientific,
or educational purposes is a threat to
the military macaw throughout its
range.
asabaliauskas on DSK5VPTVN1PROD with RULES
C. Disease or Predation
Disease
Studies of macaws indicate that this
species is susceptible to many bacterial,
parasitic, and viral diseases, particularly
in captive environments (Kistler et al.
2009, p. 2,176; Portaels et al. 1996, p.
319; Bennett et al. 1991). Viral diseases
seem to be more prevalent and
subsequently more studied in parrots
than bacteria and parasites. Psittacines
are prone to many viral infections such
as retrovirus, pox virus, and paramyxo
virus, and captive-held birds seem
particularly susceptible (Gaskin 1989,
pp. 249, 251, 252). A highly fatal
disease, Pacheco’s parrot disease, is also
caused by a virus (Simpson et al. 1976,
p. 218). After infection from this virus,
death occurs suddenly without apparent
sign of sickness other than some mild
nasal discharge and lethargy (Simpson
et al. 1976, p. 211). However, as
transmission of this disease is mainly
through nasal discharge and feces, it is
less likely to happen in open habitat in
the wild than in a confined aviary,
particularly because in the wild this
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
species has been observed to alternate
nest sites based on food availability
(Chosset et al. 2004, pp. 35–39).
Another disease, proventricular
dilatation disease (PDD), may be one of
the worst diseases known to affect
parrots (Kistler et al. 2008, p. 2). PDD
has been documented in several
continents in more than 50 different
parrot species and in free-ranging
species in at least five other orders of
birds (Kistler et al. 2008, p. 2). It is not
clear if some diseases observed in birds
in captivity also occur in the wild with
the same frequency. However, because
the populations of military macaws are
small and widely distributed, disease is
less of a concern because diseases tend
to be more easily transmitted between
individuals within close range, and wild
birds disperse and are not constantly in
close proximity. Also, captive
conditions in aviaries make birds more
susceptible to disease where the stress
of confinement combined with
inadequate diet can reduce the ability of
birds to fight disease.
We have no evidence of significant
adverse impacts to wild populations of
military macaws due to disease. Disease
is a normal occurrence within wild
populations. There is no indication that
disease occurs to an extent that it is a
threat. Based on the best available
scientific and commercial information,
we find that disease is not a threat to the
military macaw in any portion of its
range now or in the future.
Predation
Eggs and chicks are more susceptible
to predation than adult macaws
(Arizmendi 2008, p. 44). Chicks and
eggs are particularly susceptible to
predation by snakes (Arizmendi 2008, p.
44), but military macaws select their
nests where they are likely to have a
high level of reproductive success.
Because military macaws generally
construct their nests in high locations
such as canyon cliffs, snake predation is
less of a concern because snakes need
tree canopy or vines to climb in order
to gain access to eggs and chicks.
Other predators known to consume
this species’ eggs include iguanas, redtailed hawks (Buteo jamaicensis), turkey
vultures (Carthates aura), and some
mammals (Arizmendi 2008, p. 44). In
the Sabino canyon, iguanas were
observed near the nesting sites.
Researchers suggested that a predator
control program here would benefit the
macaws (Arizmendi 2008, p. 45).
Macaws frequently exhibit alarmed
behavior when red-tailed hawks and
turkey vultures approach their nests
(Arizmendi 2008, p. 44). In Argentina, a
flock of parrots was attacked by a pair
PO 00000
Frm 00017
Fmt 4701
Sfmt 4700
59991
of peregrine falcons (Falco peregrinus),
which also nest in ravines (Navarro et
al. 2008, p. 6). However, although
parrots and falcons can be combative,
the peregrine falcon, which normally
consumes small mammals and birds, is
not thought to be a natural predator of
the military macaw (Bradley et al. 1991,
p. 193). Due to its large size and careful
nest site selection, the military macaw
is less susceptible to predation by both
´
land and aerial predators (Florez and
Sierra 2004, pp. 2–3). However, even
limited predation is still a concern in
part because removal of potentially
reproductive adults from the breeding
pool can have a significant effect on
small populations by destroying macaw
mating pair bonds (Kramer and Drake
2010, p. 11). Additionally, studies on
similar species in similar Andean
habitats indicate that vulnerability to
predation by generalist predators
increases with increased habitat
fragmentation and smaller patch sizes
´
(Arango-Velez and Kattan 1997, p. 140).
Because each population of military
macaws is small, with usually fewer
than 100 individuals, and because this
species mates for life, even low levels of
predation are likely to have a significant
effect on the species.
Summary of Factor C
Diseases associated with military
macaws in the wild are not well
documented. Although there is evidence
that diseases occur in parrots in the
wild, we found no information that
diseases affect this species to the degree
that they are negatively impacting this
species in the wild. Because the
populations are distributed across such
a large area, these populations have
resiliency against impacts from disease
if one population is affected by a disease
outbreak. Conversely, although disease
in the wild is not a concern, predation
does remain a concern; there is evidence
that predation on this species occurs
often enough that it can have a
significant impact. Because of the
species’ small and declining population
size, tendency to mate for life, low
reproductive capacity, and existence in
isolated habitat fragments, even
minimal predation renders the species
more vulnerable to local extirpations.
Therefore, we find that predation,
compounded by ongoing habitat loss
and poaching, is a threat to the military
macaw.
D. The Inadequacy of Existing
Regulatory Mechanisms
Regulatory mechanisms to protect a
species could potentially fall under
categories such as regulation of trade,
wildlife management, parks
E:\FR\FM\02OCR3.SGM
02OCR3
59992
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
management, or forestry management.
Regulatory mechanisms could be at the
local, national, or international levels.

International Wildlife Trade (CITES)
A specimen of a CITES-listed species
may be imported into or exported (or
reexported) from a country only if the
appropriate permit or certificate has
been obtained prior to the international
trade and it is presented for clearance at
the port of entry or exit. The Conference
of the Parties (CoP), which is the
decisionmaking body of the Convention
and comprises all its member countries,
has agreed on a set of biological and
trade criteria to help determine whether
a species should be included in
Appendix I or II. The military macaw is
listed in Appendix I. For Appendix-I
species, both an export permit (or
reexport certificate) must be issued by
the country of export and an import
permit from the country of import must
be obtained prior to international trade.
An export permit for species listed in
either Appendix I or II may only be
issued if the country of export
determines that:
• The export will not be detrimental
to the survival of the species in the wild
(CITES Article III(2) and Article IV(2));
• The specimen was legally obtained
according to the animal and plant
protection laws in the country of export;
• For live animals or plants, they are
prepared and shipped for export to
minimize any risk of injury, damage to
health, or cruel treatment; and
• For Appendix I species, an import
permit has been granted by the
importing country.
Except in certain cases, such as
specific scenarios for approved captivebreeding programs, the import of an
Appendix-I species requires the
issuance of both an import and export
permit. Import permits are issued only
after the importing country determines
that it will not be used for primarily
commercial purposes (CITES Article
III(3)) and that the proposed recipient of
live animals or plants is suitably
equipped to house and care for them.
Thus, with few exceptions, Appendix-I
species cannot be traded for commercial
purposes.
The CITES Treaty requires Parties
(member countries) to have adequate
legislation in place for its
implementation. Under CITES
Resolution Conference 8.4 (Rev. CoP15)
and related decisions of the CoP, the
National Legislation Project evaluates
whether Parties have adequate domestic
legislation to successfully implement
the Treaty (CITES 2011a). In reviewing
a country’s national legislation, the
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
CITES Secretariat evaluates factors such
as:
• Whether a Party’s domestic laws
prohibit trade contrary to the
requirements of the Convention,
• Whether a Party has penalty
provisions in place for illegal trade, and
if they have designated the responsible
Scientific and Management Authorities,
and
• Whether a Party’s legislation
provides for seizure of specimens that
are illegally traded or possessed.
The CITES Secretariat has determined
that the legislation of Argentina,
Colombia, Mexico, and Peru is in
Category 1, meaning they meet all the
requirements to implement CITES.
Bolivia, Ecuador, and Venezuela were
determined to be in Category 2, with a
draft plan, but not enacted (https://
www.cites.org, SC62 Document 23, pp.
7–8). This means the Secretariat
determined that the legislation of
Bolivia, Ecuador, and Venezuela meet
some, but not all, of the requirements
for implementing CITES. Based on the
decrease in reported international trade,
CITES and the range countries for this
species have effectively controlled legal
international trade of this species.
Therefore, we find CITES is an effective
mechanism for preventing
overexploitation for international trade
in this species.
Parks and Habitat Management
We are focusing our evaluation of the
potential threats to this species
primarily to parks for the following
reasons. Most suitable habitat, primary
forest, only remains in these protected
areas. The best available information
suggests that this species is now mostly
found in protected areas such as parks,
in part because this is where suitable
habitat remains for the species.
Additionally, the majority of the
information available regarding the
potential threats to the species pertains
to the parks, where the species is
usually found. Our rationale is
supported by Cowen, who noted that
encounter rates for large macaw species
were generally higher in primary forests
(2008, p. 15), which tend to be located
in areas with protected status.
Throughout this species’ range, we
found that many of the threats that
occur to this species are the same or
similar. Threats generally consist of
various forms of habitat loss or
degradation. Each range country for this
species has protections in place, but for
reasons such as limited budgets and
limited enforcement capabilities, the
laws and protections are generally not
able to adequately protect the species.
PO 00000
Frm 00018
Fmt 4701
Sfmt 4700
Research has found that tropical parks
have been surprisingly effective at
protecting ecosystems and species
within boundaries designated as parks
or other protected status despite
underfunding and pressures for
resources (Oliveira et al. 2007, p. 1,235;
Bruner et al. 2001, p. 126; Terborgh
1999, entire). Bruner’s study found that
protected areas are especially effective
in preventing land clearing. It found
that, in 40 percent of parks, land that
had formerly been under cultivation and
that was incorporated into park
boundaries had actually recovered. This
subsequently led to an increase in
vegetative cover. The study also found
that 83 percent of parks were successful
at mitigating encroachment (Bruner et
al. 2001, p. 125). It concluded that the
conditions inside the parks were
significantly better than in their
surrounding areas (Bruner et al. 2001, p.
125). Oliveira et al. found that forests in
conservation units were four times
better at protecting against deforestation
than unprotected areas (2007, p. 1,235).
However, despite these protections, this
species has experienced threats such
that their populations are now so small
(generally fewer than 100 in each
population) that any pressure now has
a more significant effect. Parks, without
management, are often insufficient to
adequately protect the species. Our
analysis of regulatory mechanisms is
discussed essentially on a country-bycountry basis, beginning with
Argentina, and is summarized at the
end. Conditions in specific parks are
discussed below.
Argentina
In 2007, Argentina enacted a law
mandating minimum standards for the
environmental protection of native
forests (Ley de Bosques). However, the
federal government has not fully
enforced the law, and provincial
governments are not in full compliance
with it (DiPaola et al. 2008, p. 2).
Argentina lacks adequate protections of
its natural environments; there is a lack
of environmental awareness and
commitment from the government to
adequately protect its resources (FAO
2007, pp. 43–44, 59–60). Provinces
usually allow landowners to decide
whether to maintain forest cover or
deforest the land. The absence of a
serious land use planning strategy,
particularly during the past 20 years,
has led to significant habitat
degradation (FAO 2007, p. 60). The
threat to native forests has remained
particularly high in the Salta Province.
As a result, a coalition of indigenous
communities and nongovernmental
organizations filed for injunctive relief
E:\FR\FM\02OCR3.SGM
02OCR3
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
in Argentina’s highest court to attempt
to combat deforestation (DiPaola et al.
2008, p. 2). In this case, the court
mandated deforestation activities to be
halted pending the completion of a
cumulative environmental impact
study. The decision forced the Salta
Province to comply with the
deforestation moratorium imposed by
the Forestry Law, and pressured the
Province to comply with the other key
provision of the law by completing an
environmental land use plan (DiPaola et
al. 2008, p. 2). Although the Forestry
Law is in place and the court case has
set a precedent for compliance with this
law, the area where this species occurs
in Argentina to the best of our
knowledge remains largely unprotected
(Navarro et al. 2008, pp. 7, 9).

Bolivia
This species primarily inhabits the
parks and protected areas in Bolivia’s
Andean region (Herzog 2011, pers.
comm.). National parks are intended to
be strictly protected; however, some
areas where the species occurs are also
designated as areas of integrated
management, which are managed for
both biological conservation and the
sustainable development of the local
communities. Bolivia attempts to
balance natural resource uses; however,
it is one of the poorest countries in
South America (MacLeod 2009, p. 6;
CIA World Factbook, accessed
December 6, 2011), and subsequently
has competing priorities. As of 2005,
Bolivia had 5 national parks, 6 national
park and integrated management natural
areas, 1 national park and indigenous
territory (or communal lands), 4
national reserves, 2 biosphere reserves,
and 3 integrated management natural
areas (ParksWatch 2005, p. 1). These
make up Bolivia’s National System of
Protected Areas ((SNAP) Servicio
Nacional de Areas Protegidas). Below
are the designations and their relevant
categorizations of protections (eLAW
2003, p. 3).
(1) Park, for strict and permanent
protection of representative ecosystems
and provincial habitats, as well as plant
and animal resources, along with the
geographical, scenic and natural
landscapes that contain them;
(2) Sanctuary, for the strict and
permanent protection of sites that house
endemic plants and animals that are
threatened or in danger of extinction;
(3) Natural Monument, to preserve
areas such as those with distinctive
natural landscapes or geologic
formations, and to conserve the
biological diversity contained therein;
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
(4) Wildlife Reserve, for protection,
management, sustainable use, and
monitoring of wildlife;
(5) Natural Area of Integrated
Management, where conservation of
biological diversity is balanced with
sustainable development of the local
population; and
(6) ‘‘Immobilized’’ Natural Reserve, a
temporary (5-year) designation for an
area that requires further research before
any official designations can be made
and during which time no natural
resource concessions can be made
within the area (Supreme Decree No.
24,781 1997, p. 3).
The foundation of Bolivia’s laws is
largely based on Bolivia’s 1975 Law on
Wildlife, National Parks, Hunting, and
Fishing (Decree Law No. 12,301 1975,
pp. 1–34), which has the fundamental
objective of protecting the country’s
natural resources. This law governs the
protection, management, utilization,
transportation, and selling of wildlife
and their products; the protection of
endangered species; habitat
conservation of fauna and flora; and the
declaration of national parks, biological
reserves, refuges, and wildlife
sanctuaries, regarding the preservation,
promotion, and rational use of these
resources (Decree Law No. 12,301 1975,
pp. 1–34; eLAW 2003, p. 2). Later,
Bolivia passed an overarching
environmental law in 1992 (Law No.
1,333 1992), with the intent of
protecting and conserving the
environment and natural resources.
Studies have shown that protected areas
have been successful in providing
protection from poaching, logging, and
other forest damage, especially when
compared to unprotected areas (Lee
2010, p. 3; Killeen et al. 2007, p. 603;
Oliveira et al. 2007, p. 1,234; Asner
2005, p. 480; Ribeiro et al. 2005, p. 2;
Gilardi and Munn 1998, p. 641).
However, pressures on the parks’
resources are increasing; these are
described below.
Within the Greater Madidi-Tambopata
Landscape, activities that could
negatively affect this species occur, and
there are competing priorities within
these protected areas. The GMTL is
divided into three contiguous areas,
with two different management
categories: A strictly protected National
Park in two sections that total 1,271,000
ha (3,140,709 ac), and a natural
integrated management area with
624,250 ha (1,542,555 ac), where
conservation and sustainable
development of the local communities
is the main purpose (Conservation
Strategy Fund (CSF) 2006, p. 29). The
most significant activities that are
having a negative impact or could in the

future in this area are the construction
of a highway within Madidi, mining for
natural resources such as gold, drilling
for oil, and a planned hydroelectric dam
(ParksWatch 2011b, p. 8; https://
www.amazonfund.eu/art-oilmadidi.html, accessed September 13,
2011; Chavez 2010, pp. 1–2). There is
limited legal hunting of this species
occurring here, but in the areas
surveyed, this species was described as
common and not exploited (Hosner et
al. 2009, p. 226). Timber extraction still
occurs in some areas (WorldLand Trust
2010, p. 1). In the rainforest and foothill
´
forest of Serranıa Sadiri within Madidi,
roads in the late 1990s spurred a rise in
the unsustainable logging of the area’s
mahogany trees, which were the most
valuable tree at the time (World Land
Trust 2010, pp. 1–2). Within the
Apolobamba protected area,
uncontrolled clearing, extensive
agriculture, grazing, and ‘‘irresponsible’’
tourism are ongoing (Auza and
Hennessey 2005, p. 81). Habitat
degradation and destruction from
grazing, forest fires, and timber
extraction are ongoing in other
protected areas, such as Tunari National
Park (Department of Cochabamba),
where suitable habitat exists for this
species (De la Vie 2004, p. 7).
Bolivia’s national policy is to
decentralize decisionmaking, and
responsibility for land planning and
natural resource management is
increasingly shifting to local and
regional governments (Wildlife
Conservation Society (WCS) 2009, pp.
2–5). However, the decentralization
process is occurring without sufficient
personnel, staff training, and
operational funds. There is little
information as to the actual protections
that Bolivia’s laws and protected areas
confer to military macaws, despite the
laws in place at the national level for its
wildlife. Threats to the species and its
habitat include unsustainable land use
practices, illegal logging, mining, road
building, oil extraction, illegal animal
trade, and hunting, which are all still
occurring within this species’ habitat
(MacLeod 2009, p. 6; WCS 2009, pp. 2–
5). The mechanisms in place are
inadequate at reducing the threat of
habitat destruction and human
disturbance within these protected
areas.
Colombia
The Colombian Government has
enacted and ratified numerous domestic
and international laws, decrees, and
resolutions for managing and conserving
wildlife and flora. Colombia currently
has 54 areas that have protected status

Protegidas (SINAP); National Natural
Parks of Colombia 2011). Of those, 33
have been declared Important Bird
Areas (IBAs). The protected area
designations are as follows: national
parks (parques nacionales), flora and
fauna sanctuaries (santuarios de fauna y
flora), flora sanctuaries (santuarios de
flora), nature reserves (reserva natural),
´
and unique natural areas (area natural
´
unica) (Law 165 of 1994). Small
populations of this species occur in
several reserves and protected areas in
Colombia (Strewe and Navarro 2003, p.
32). These protected areas in Colombia
offer various degrees of protection to the
species.
In 2003, conservation priorities were
identified for its bird species, a
conservation corridor was designed, and
a habitat conservation strategy within
the San Salvador valley was developed
(Strewe and Navarro 2003, p. 29). The
private Buena Vista Nature Reserve was
established and protects approximately
400 ha (988 ac) of tropical wet lowland
forest and wet premontane forest on the
northern slope of the Sierra Nevada. It
encompasses extensive primary forests
along an altitudinal gradient of 600 to
2,300 m (1,968 to 7,545 ft) and forest
patches and secondary forest at
elevations between 450 to 600 m (1,476
to 1,968 ft). The reserve is adjacent to
the Sierra Nevada de Santa Marta
National Park and the Kogi-Malayo
Indian reserve (Strewe and Navarro
2003, p. 29).
A conservation project focusing on
´
´
the coffee zone of the middle Rıo Frıo
is ongoing, and its goal is to create a
conservation corridor connecting
natural habitats and shade-grown coffee
plantations (Strewe and Navarro 2004,
p. 51). The establishment of the private
nature reserve, Buena Vista, was the
first step to conserve the foothill forest
ecosystems. This was done in close
cooperation with a local organization,
Grupo Ecologico Defensores de la
Naturaleza–Campesinos de Palomino
(Strewe and Navarro 2003, pp. 34–35).
The Pro-Sierra Nevada de Santa Marta
Foundation (FPSNSM) maintains a
permanent monitoring station at Buena
Vista nature reserve. FPSNSM is
working toward sustainable
development projects in cooperation
with local communities, national park
units, and coffee-grower committees in
the region. This includes educational
campaigns to limit hunting. Habitat
management takes place on private
lands in the lowlands and foothills of
the San Salvador valley to reduce the
pressure on the remaining natural forest
habitats, including a reforestation
program using native tree species.
Additionally, forest reserves have been

established as part of a network of
private nature reserves in the valley
(Strewe and Navarro 2003, pp. 35–36).
Resource management in Colombia is
highly decentralized. Colombian
environmental management has been
divided between the national and
regional levels since the 1950s.
Governmental institutions responsible
for oversight appear to be under
resourced (ITTO 2006, p. 222) and
unable to adequately manage species
such as the military macaw. Resources
are managed within local municipalities
by one of 33 ‘‘Autonomous Regional
Corporations’’ known as CARs
´
(Corporaciones Autonomas Regionales)
(Blackman et al. 2006, p. 32). CARs are
described as corporate bodies of a
public nature, endowed with
administrative and financial autonomy
to manage the environment and
renewable natural resources,
implemented through Law 99 of 1993
(p. 32). Each department (analogous to
U.S. state designations) within
Colombia is managed by a separate local
entity. These corporations grant
concessions, permits, and
authorizations for forest harvesting
(ITTO 2006, p. 219).
As of 2005, 40 percent of Colombia’s
public resources were managed by local
municipalities, making Colombia one of
the most decentralized countries in
terms of forestry management in Latin
America (Blackman et al. 2006, p. 36).
Monitoring of resource use and forest
development authorized by these
corporations is conducted mostly by
local nongovernmental organizations.
The International Tropical Timber
Organization (ITTO) considers the
Colombian forestry sector to be lacking
in law enforcement and on-the-ground
control of forest resources, with no
specific standards for large-scale
forestry production, no forestry
concession policies, and a lack of
transparency in the application of the
various laws regulating wildlife and
their habitats (ITTO 2006, p. 222).
Consequently, there is currently no
effective vehicle for overall coordination
of species management for
multijurisdictional species such as the
´
military macaw. Fundacion ProAves
developed a conservation plan for 2010
to 2020 for several parrot species,
including the military macaw (Botero´
Delgadillo and Paez 2011, p. 7).
However, it is unclear if or when it will
be adopted by the Government of
Colombia.
Additionally, despite protections,
forest loss continues almost unabated in
the mountains of the Sierra Nevada,
demonstrating that formal protections
and regulatory mechanisms are
PO 00000
Frm 00020
Fmt 4701
Sfmt 4700
inadequate. In this area, El Congo
Reserve currently may be the only
secure nesting site for the military
macaw, but it is too small (40 ha; 99 ac)
to conserve viable populations.
Efforts are occurring in Colombia to
protect and monitor its species,
although they do not appear to be
adequate to combat the threats to this
species. One management tool that
Colombia has recently developed is a
bird-watching strategy in these
protected areas to monitor and report on
bird species such as the military macaw,
in conjunction with ecotourism
(National Natural Parks of Colombia
2011). Despite the efforts in place, there
is a lack of information available about
the status of this species and its habitat
in Colombia. There is no clear
information about the status of the
species in Colombia, particularly its
population trend. We are unable to
determine that this conservation
strategy will sufficiently mitigate threats
to the military macaw, nor are we able
to find that the regulatory mechanisms
in place in Colombia are adequate. The
species population is small in Colombia,
and threats to its habitat still exist.
Ecuador
In Ecuador, the military macaw is
considered to be very rare (Arcos-Torres
and Solano-Ugalde 2008, p. 72). It has
been observed in the areas of Sumaco
and Zamora-Chinchipe (Youth 2009, p.
1; Snyder et al. 2000, p. 125) and
recently at Kichwa River Reserve
´
(Reserva Kichwa Rıo), within the Gran
Sumaco Biosphere Reserve Guacamayos
(Arcos-Torres and Solano-Ugalde 2008,
p. 72). This species is categorized as
´
endangered ‘‘en peligro de extincion’’
(Arcos-Torres and Solano-Ugalde 2008,
p. 69) in Ecuador. It is protected by
Decree No. 3,516 of 2003 (Unified Text
of the Secondary Legislation of the
Ministry of Environment) (EcoLex
2003b, pp. 1–2 and 36). This decree
summarizes the laws governing
environmental policy in Ecuador and
provides that the country’s biodiversity
be protected and used primarily in a
sustainable manner.
Habitat destruction is ongoing and
extensive in Ecuador (Mosandl et al.
2008, p. 37; Butler 2006b, pp. 1–3; FAO
2003b, p. 1). Unsustainable forest
harvest practices likely continue to
impact the military macaw’s habitat. In
2004, Ecuador Law No. 17 (Faolex 2004,
pp. 1–29) amended the Forest Act of
1981 (Law No. 74) to include five
criteria for sustainable forest
management: (i) Sustainable timber
production; (ii) the maintenance of
forest cover; (iii) the conservation of
biodiversity; (iv) co-responsibility in

management; and (v) the reduction of
negative social and environmental
impacts (ITTO 2006, p. 225; Aguilar and
Vlosky 2005, pp. 9–10). In 2001, the
Ecuadorian Government worked with
the private sector to develop a system of
monitoring and control of forest harvest
practices. However, in 2003, the
Supreme Court of Ecuador declared the
control system unconstitutional, and
new control systems were being
developed (ITTO 2006, p. 225).
Approximately 70 percent of the forest
products harvested are harvested
illegally, or are used as fuel wood, or are
discarded as waste (ITTO 2006, p. 226;
Aguilar and Vlosky 2005, p. 4). Because
the extractive harvesting industry is not
monitored, the extent of the impact is
unknown; however, the best available
information indicates that habitat
degradation negatively affects this
species in Ecuador.
The Ecuadorian Government
recognizes 31 different legal categories
of protected lands (e.g., national parks,
biological reserves, geo-botanical
reserves, bird reserves, wildlife reserves,
etc.). The colony in Kichwa River
Reserve Macaw receives some legal
protections by being in a Reserve.
However, a study published in 2002
concluded that, although 14 percent of
Ecuador is categorized as national
reserve network (Sierra et al. 2002, p.
107), the system does not provide
adequate protection for its ecosystems.
As of 2006, the amount of protected
land (both forested and nonforested) in
Ecuador totals approximately 4.67
million ha (11.5 million ac) (ITTO 2006,
p. 228). However, only 38 percent of
these lands have appropriate
conservation measures in place to be
considered protected areas according to
international standards (i.e., areas that
are managed for scientific study or
wilderness protection, for ecosystem
protection and recreation, for
conservation of specific natural features,
or for conservation through management
intervention) (IUCN 1994, pp. 17–20).
The ITTO, as of 2006, considered
ecosystem management and
conservation in Ecuador, including
effective implementation of mechanisms
that would protect the military macaw
and its habitat, to be lacking (ITTO
2006, p. 229).
Although this colony has persisted for
about 150 years (Huatatoca, pers. comm.
in Arcos-Torres and Solano-Ugalde
2008, p. 72), it may be affected by
logging and the resulting deforestation
on nearby land (Arcos-Torres and
Solano-Ugalde 2008, p. 72). The best
available information indicates that onthe-ground enforcement of Ecuador’s
laws, oversight of the local jurisdictions,
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
and implementing and regulating
activities are ineffective in conserving
the military macaw and its habitat in
Ecuador. Researchers suggest that the
apparent lack of this species in Ecuador
is related to lack of existing suitable
sites (large areas containing appropriate
feeding, nesting, and breeding habitat)
for the formation of breeding colonies.
The governmental institutions
responsible for natural resource
oversight in Ecuador appear to be
under-resourced, and to our knowledge,
there is a lack of law enforcement on the
ground. Despite the creation of a
national forest plan, the best available
information indicates there is a lack of
capacity to implement this plan due to
inconsistencies in application of
regulations, and discrepancies between
actual harvesting practices and forestry
regulations. These inadequacies have
facilitated logging, clearing for
agriculture, subsistence farming, and
road development. Habitat conversion
and alteration are ongoing within
Ecuador, including within protected
areas.
Mexico
This species is listed as endangered
and is regulated under the general terms
of the General Law of Ecological
Balance and Environmental Protection
´
(Ley General del Equilibrio Ecologico y
´
Proteccion al Ambiente (LGEEPA)), the
General Wildlife Law (Ley General de
Vida Silvestre (LGVS)), and also under
CITES (CEC 2003, unpaginated). NOM–
059–ECOL–2010 establishes a list of
wildlife species classified as either in
danger of extinction (endangered),
threatened, under special protection, or
probably extinct in the wild
(Government of Mexico 2002, p. 6). All
use of endangered and threatened
species requires a special permit from
the Secretariat of the Environment and
´
Natural Resources (Secretarıa del Medio
Ambiente y Recursos Naturales
(SEMARNAT). SEMARNAT’s main goal
is to protect, restore, and conserve its
ecosystems and natural resources.
Under Mexico’s General Wildlife Law,
the use of these protected species,
including the military macaw, may be
authorized only when priority is given
to the collection and capture for
restoration, repopulation, and
´
reintroduction activities (Comision
Nacional Para El Conocimiento y Uso de
la Biodiversidad 2009, unpaginated;
CEC 2003, unpaginated).
International trade of Mexico’s
wildlife is also managed by
SEMARNAT. In 2008, Mexico passed
Article 60_2 to amend its General
Wildlife Law. The article bans the
capture, export, import, and reexport of
PO 00000
Frm 00021
Fmt 4701
Sfmt 4700
59995
any species of the Psittacidae (parrot)
family whose natural distribution is
´
´
within Mexico (Cantu and Sanchez
2011, p. 1). It allows authorizations for
the removal of individuals from the
wild to be issued only for conservation
purposes, or to accredited academic
institutions for scientific research.
However, it does not appear to be
adequate based on investigations of
trade of Mexico’s native parrot species.
The military macaw falls under the
jurisdiction of several other laws in
Mexico. The General Law on
Sustainable Forest Management (Ley
General de Desarrollo Forestal
Sustenable (LGDFS 2003)) governs
forest ecosystems in Mexico, including
military macaw habitat. This law
formalizes the incorporation of the
forest sector in a broader environmental
framework. Under this law, harvesting
of forests requires authorization from
SEMARNAT. It also requires that
harvesting forests is based on a
technical study and a forest
management plan (GOM 2010, p. 24). A
number of additional laws complement
the 2003 law in regulating forest use.
The LGEEPA regulates activities for
protecting biodiversity and reducing the
impact on forests and tropical areas of
certain forest activities; the LGVS
governs the use of plants and wildlife
found in the forests; the General Law on
Sustainable Rural Development (Ley
General de Desarrollo Rural Sustentable)
provides guidance for activities aimed at
protecting and restoring forests within
the framework of rural development
programs; and the Agrarian Law (Ley
Agraria) governs farmers’ ability to use
forest resources on their land (Anta
2004, in USAID 2011, unpaginated).
Another law regulating portions of the
military macaw’s habitat is the National
System of Protected Natural Areas
´
(Sistema Nacional de Areas Naturales
Protegidas (SINANP)). These protected
natural areas are created by presidential
decree, and the activities in them are
regulated under the LGEEPA, which
requires that the protected natural areas
receive special protection for
conservation, restoration, and
´
development activities (Comision
´
Nacional de Areas Naturales Protegidas
(CONANP) 2011, unpaginated). These
natural areas are categorized as:
Biosphere Reserves, National Parks,
Natural Monuments, Areas of Natural
Resource Protection, Areas of Protection
of Flora and Fauna, and Sanctuaries
(CONANP 2011, unpaginated).
Conservation strategies in Mexico rely
heavily on natural protected areas, and
biosphere reserves comprise most of the
designated protected area in the country
(Figueroa and Sanchez 2008, pp. 3324,
E:\FR\FM\02OCR3.SGM

59996
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
asabaliauskas on DSK5VPTVN1PROD with RULES
3234). The military macaw occurs in or
near at least four biosphere reserves.
Although some areas where this species
occurs have protected status, Figueroa
and Sanchez (2008, entire) found that,
for example, the Sierra Gorda Biosphere
Reserve was ineffective (as opposed to
effective or weakly effective). This study
specifically evaluated the effectiveness
of Mexico’s protected areas for
preventing land use and land cover
change. It assessed the effectiveness of
national protected areas (NPAs) by
quantifying (1) the rate of change and (2)
the total extent of change, between 1993
and 2002, as well as (3) the percentage,
in 2002, of areas transformed by human
use; transformed areas included
agriculture, cultivated and induced
pastures, human settlements, and
forestry plantations. The rate of change
of transformed areas inside each NPA
was also compared with that estimated
for an equivalent area surrounding the
NPA. They selected 69 federal decreed
NPAs (out of 160 NPAs decreed in
Mexico) that were 1,000 ha (2,471 ac) or
larger, which is the minimum area for
conserving ecosystems in Mexico
(Figueroa and Sanchez 2008, p. 3,225;
´˜
´
Ordonez and Florez-Villela 1995, p. 11).
The study found that, overall, only
approximately 54 percent of protected
areas, including 65 percent of biosphere
reserves, were effective.
Peru
In Peru, this species is listed as
vulnerable under Supreme Decree No.
034–2004–AG (2004, p. 276,855), and its
protections fall under the jurisdiction of
the National Institute of Natural
Resources (Instituto Nacional de
Recursos Naturales, INRENA). This
Decree prohibits hunting, take,
transport, and trade of protected
species, except as permitted by
regulation. The military macaw is
thought to occur in at least three areas
with protected status in Peru. The
Peruvian national protected area system
includes several categories of habitat
protection (refer to Factor A). National
reserves, national forests, communal
reserves, and hunting reserves are
managed for the sustainable use of
resources (IUCN 1994, p. 2). The
designations of national parks,
sanctuaries, and protection forests are
established by supreme decree that
supersedes all other legal claim to the
land and, thus, these areas tend to
provide some form of habitat protection
´
(Rodrıguez and Young 2000, p. 330).
However, limited information is
available with respect to the status of
this species in Peru. We do not know if
the occurrence of the military macaw
within protected areas in Peru actually

protects the species or mitigates threats
to the species, and to what extent these
protections are effective.
Venezuela
In Venezuela, the military macaw is
´
thought to exist in two parks: El Avila
National Park and Henri Pittier National
Park. Limited information about the
status of this species is available in
Venezuela. Henri Pittier National Park
(107,800 ha; 266,380 ac) was declared
the first national park in Venezuela in
1937. This park is the largest national
park of the Cordillera de la Costa
(Coastal Mountain Range) region. The
principal threats to this park include:
fire, human encroachment, solid waste
buildup, pollution, hunting, and limited
resources for effective park management
(ParksWatch 2011g, unpaginated). In
many cases, the intensity of threats has
increased. Prior to 1994, a team of
government representatives, NGOs,
universities, and aviculturists in
Venezuela had developed both an action
plan for the conservation of parrots and
a book containing information on parrot
biology (Morales et al. 1994, in Snyder
2000, p. 125). However, currently, it is
unclear what conservation initiatives
are occurring.
´
El Avila National Park (81,800 ha;
202,132 ac in size), is located along the
central stretch of the Cordillera de la
Costa Mountains in northern Venezuela.
The most immediate threats to the park
are forest fires and illegal settlements,
which occur primarily near Caracas
(ParksWatch 2011f, unpaginated).
ParksWatch notes that the areas closest
to the city have experienced more
problems in the more isolated northern
´
slope and eastern sector of El Avila.
Other threats in this park include the
presence of nonnative plants and
poaching.
Summary of Factor D
In Argentina, Ecuador, Peru, and
Venezuela, we recognize that
conservation activities are occurring,
and that these activities may have a
positive effect on the species at the local
population level. Parrots, in general, are
long-lived with low reproductive rates,
traits that make them particularly
sensitive to poaching and other threats
such as habitat loss (Lee 2010, p. 3;
Thiollay 2005, p. 1,121; Wright et al.
2001, p. 711). The primary threats to
this species historically have been the
loss of habitat and capture for the pet
trade (Strewe and Navarro 2003, p. 33).
Since regulatory mechanisms such as
CITES and the WBCA have been put
into place, particularly since 1992,
much of the legal international trade in
the military macaw has declined (see
PO 00000
Frm 00022
Fmt 4701
Sfmt 4700
Factor B discussion, above). However,
those pressures prior to the military
macaw’s listing under CITES and the
WBCA contributed significantly to the
decline in population numbers for this
species. Since then, the species’ habitat
has become fragmented, its range has
reduced, and its populations have more
difficulty finding suitable habitat.
Each of these countries has enacted
laws to protect its wildlife and habitat.
The populations of this species in these
four countries are likely to number from
fewer than 100 to a few hundred
individuals. There are numerous threats
acting on this species; its populations
have severely declined. In some cases,
the actual causes of decline may not be
readily apparent and a species may be
affected by more than one threat in
combination. Habitat conservation
measures within these range countries
do not appear to sufficiently mitigate
future habitat losses. Habitat loss and
degradation continue to occur within
these countries; the best available
information does not indicate that the
existing regulatory mechanisms have
mitigated these threats in the range of
this species. Because these populations
of this species are very small in these
countries, any impact is likely to have
a significant impact on the species;
therefore, we are unable to conclude
that regulatory mechanisms in place for
this species and its habitat are adequate.
Bolivia, Colombia, and Mexico have
enacted various laws and regulatory
mechanisms for the protection and
management of this species and its
habitat. Although information available
is limited, the best evidence suggests
that the military macaw exists in small
populations in several large protected
areas within these countries. As
discussed under Factor A, the military
macaw prefers primary forests and
woodlands and complex habitat that
offers a variety of food sources. Its
suitable habitat has been severely
constricted due to deforestation. In
these three countries, there is evidence
of threats to this species due to activities
such as habitat destruction and
degradation, poaching, construction of
roads, and mining, as well as decreased
viability due to small population sizes,
despite the regulatory mechanisms in
place. We acknowledge that research
and conservation programs are
occurring in these countries. However,
based on the best available information,
we find that the existing regulatory
mechanisms for these countries are
either inadequate or inadequately
enforced in order to protect the species
or to mitigate ongoing habitat loss and
degradation, poaching, and the severe
population decline of this species.

Habitat conservation measures within
these range countries do not appear to
sufficiently mitigate future habitat
losses.
Based on the best available
information, we are unable to conclude
that the existing regulatory mechanisms
currently in place sufficiently mitigate
threats to the military macaw
throughout its range. Therefore, we find
that the existing regulatory mechanisms
are inadequate to mitigate the current
threats to the continued existence of the
military macaw throughout its range
now and into the future.

E. Other Natural or Manmade Factors
Affecting Its Continued Existence
Small Population Size
Small, declining populations can be
especially vulnerable to environmental
disturbances such as habitat loss
(O’Grady 2004, pp. 513–514). Removal
of a few birds from a population of 100
can have a greater effect than removal of
a few birds from larger populations. In
order for a population to sustain itself,
there must be enough reproducing
individuals and habitat to ensure its
survival. Conservation biology defines
this as the ‘‘minimum viable
population’’ requirement (Grumbine
1990, pp. 127–128). This requirement
may be between 500 and 5,000
individuals depending on variability,
demographic constraints, and
evolutionary history. The military
macaw occurs in relatively small
populations (ranging from a few pairs to
approximately 100 individuals, with the
total population size that is likely no
greater than a few thousand). The
military macaw relies on specific habitat
to provide for its breeding, feeding, and
nesting. Historically, the military
macaw existed in much higher numbers
in more continuous, connected habitat.
Its suitable habitat is becoming
increasingly limited, and is not likely to
expand in the future.
The combined effects of habitat
fragmentation and other factors on a
species’ population can have profound
effects and can potentially reduce a
species’ respective effective population
by orders of magnitude (Gilpin and
´
Soule 1986, p. 31). For example, an
increase in habitat fragmentation can
separate populations to the point where
individuals can no longer disperse and
breed among habitat patches, causing a
shift in the demographic characteristics
of a population and a reduction in
´
genetic fitness (Gilpin and Soule 1986,
p. 31). This is especially applicable for
a species such as the military macaw
that was once wide-ranging. It has lost
a significant amount of its historical
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
range due to habitat loss and
degradation. Furthermore, as a species’
status continues to decline, often as a
result of deterministic forces such as
habitat loss or overutilization, it will
become increasingly vulnerable to other
impacts. If this trend continues, its
ultimate extinction due to one or more
stochastic (random or unpredictable)
events becomes more likely. The
military macaw’s current occupied and
suitable range is highly reduced and
severely fragmented. The species’ small
population size, its reproductive and
life-history traits, and its highly
restricted and severely fragmented range
increase this species’ vulnerability to
other threats.
Climate Change
Consideration of ongoing and
projected climate change is a
component of our analysis under the
ESA. The term ‘‘climate change’’ refers
to a change in the mean, variability, or
seasonality of climate variables over
time periods of decades or hundreds of
years (Intergovernmental Panel on
Climate Change (IPCC) 2007, p. 78).
Forecasts of the rate and consequences
of future climate change are based on
the results of extensive modeling efforts
conducted by scientists around the
world (Solman 2011, p. 20; Laurance
˜
and Useche 2009, p. 1,432; Nunez et al.
2008, p. 1; Margeno 2008, p. 1; Meehl
et al. 2007, p. 753). Climate change
models, like all other scientific models,
produce projections that have some
uncertainty because of the assumptions
used, the data available, and the specific
model features. The science supporting
climate model projections as well as
models assessing their impacts on
species and habitats will continue to be
refined as more information becomes
available. While projections from
regional climate model simulations are
informative, various methods to
downscale projections to more localized
areas in which the species lives are still
imperfect and under development
˜
(Solman 2011, p. 20; Nunez et al. 2008,
p. 1; Marengo 2008, p. 1). The best
available information does not indicate
that climate change is impacting this
species such that it is a threat.
Summary of Factor E
A species may be affected by more
than one threat acting in combination.
Impacts typically operate
synergistically, particularly when
populations of a species are decreasing.
Initial effects of one threat factor can
later exacerbate the effects of other
´
threat factors (Gilpin and Soule 1986,
pp. 25–26). Further fragmentation of
populations can decrease the fitness and

reproductive potential of the species,
which will exacerbate other threats.
Within the preceding review of the five
factors, we have identified multiple
threats that may have interrelated
impacts on this species. The most
significant threats are habitat loss and
poaching, particularly because the
species has such a small and fragmented
population, and it requires a large range
and variety of food sources. Lack of a
sufficient number of individuals in a
local area or a decline in their
individual or collective fitness may
cause a decline in the population size,
despite the presence of suitable habitat
patches. For example, the species’
behavior of not nesting in areas where
depredation or disturbance is likely may
mean that a nest site is ‘‘abandoned’’
before nesting is even attempted. Thus,
the species’ productivity may be
reduced because of any of these threats,
either singularly or in combination.
These threats occur at a sufficient scale
so that they are affecting the status of
the species now and will in the future.
In addition, the species’ current range
is highly restricted and severely
fragmented. The species’ small
population size, its reproductive and
life-history traits, and its highly
restricted and severely fragmented range
increase the species’ vulnerability to
adverse natural events and manmade
activities that destroy individuals and
their habitat. The susceptibility to
extirpation of limited-range species can
occur for a variety of reasons, such as
when a species’ remaining population is
already too small or its distribution too
fragmented such that it may no longer
be demographically or genetically viable
(Harris and Pimm 2004, pp. 1,612–
1,613). Therefore, we find that the
species’ small population size, in
combination with other threats
identified above, is a threat to the
continued existence of the military
macaw throughout its range now and in
the future.
Finding and Status Determination for
the Military Macaw
We find that this species is
endangered based on the above
evaluation, and we are listing this
species as endangered due to the threats
described above that continue to act on
this species. Within the preceding
review of the five factors, we identified
multiple threats that may have
interrelated impacts on the species. For
example, the productivity of military
macaws may be reduced because of the
effects of poaching and habitat loss,
which are expected to continue to act on
the species in the future. In cases where
populations are very small, species mate

for life, and birds produce small clutch
sizes, these effects are exacerbated. The
susceptibility to extirpation of species
with small and declining populations
can occur for a variety of reasons, such
as when a species’ remaining
population is already too small or its
distribution too fragmented such that it
may no longer be demographically or
genetically viable (Harris and Pimm
2004, pp. 1,612–1,613). This species
exists generally in very small and
fragmented populations, usually in
areas with some form of protected status
in Mexico, Bolivia, Peru, and Colombia,
and to a limited extent Ecuador,
Venezuela, and Argentina. Its lifehistory traits (such as mating for life and
small clutch size) make it particularly
susceptible to extinction because its
populations are so small. Based on our
review of the best available scientific
and commercial information pertaining
to the five factors, we found that many
of these threats are similar throughout
the species’ range.
In four of the countries (Argentina,
Ecuador, Peru, and Venezuela), the
populations are extremely small, and
very little information about the status
of the species is available in many parts
of its range. It is not necessarily easy to
determine (nor is it necessarily
determinable) which potential threat is
the operational threat. However, we
believe that these threats, either
individually or in combination, are
likely to occur at a sufficient
geographical scale to significantly affect
the status of the species. Additionally,
although we do not have precise genetic
information about populations
throughout this species’ range, it is
likely that there is some genetic transfer
between populations. We believe this
based on its demonstrated ability to fly
long distances in search of food sources
(Chosset and Arias 2010, p. 5). The most
significant threat, habitat loss and
degradation, is prevalent throughout
this species’ range. Its suitable habitat
has severely contracted, and habitat loss
is likely to continue into the future. We
do not find that the factors affecting the
species are likely to be sufficiently
ameliorated in the foreseeable future.
Therefore, we find that listing the
military macaw is warranted throughout
its range, and we propose to list the
military macaw as endangered under
the ESA.

Great Green Macaw
Taxonomy
The great green macaw (Ara ambiguus
or ambigua, Linnaeus, 1766; Bechstein,
1811) is in the parrot (Psittacidae)
family. It is known by various common
names such as lapa verde, Buffon’s
macaw, Guacamayo verde mayor, Guara
verde, and Papagayo de Guayaquil. It
occurs as two subspecies. The nominate
subspecies, Ara a. ambiguus, occurs
from Honduras to north-west Colombia.
The subspecies A. a. guayaquilensis
occurs in western Ecuador (Rodriguez¨
Mahecha et al. 2002, p. 116; Fjeldsa et
al. 1987, pp. 28–31). There are believed
to be only around 100 individuals of A.
a. guayaquilensis in two areas in
Ecuador. This subspecies has a smaller
bill with greener underside of the flight
and tail feathers than the nominate
subspecies (Juniper and Parr 1998, p.
423). Avibase and ITIS both recognize
these subspecies (https://www.itis.gov
and https://avibase.bsc-eoc.org/
avibase.jsp, accessed May 5, 2014).
There is no universally accepted
definition of what constitutes a
subspecies, and the use of the term
subspecies varies among taxonomic
groups (Haig and D’Elia 2010, p. 29). To
be operationally useful, subspecies must
be discernible from one another (i.e.,
diagnosable) and not merely exhibit
mean differences (Patten and Unitt
2002, pp. 28, 34). This element of
discernibility is a common thread that
runs through all subspecies concepts.
Regarding the great green macaw, all
populations or subspecies of Ara
ambigua essentially face similar threats,
all are generally in the same region
(Central and northern South America),
and all have small populations. In other
words, they are not discernible between
populations. For the purpose of this
proposed rule and based on the best
available information, we recognize all
populations of great green macaws as a
single species.
Description
This species ranges between 77 and
90 cm (30 and 35 inches) in length and
has a red frontal band above a large
black bill, bare facial features with black
lines, blue flight feathers on the superior
feathers and olive inferior feathers, blue
lower back, and orange tail (Juniper and
Parr 1998, pp. 423–424). It is the second
largest New World macaw. This species
is not sexually dimorphic, meaning
there are no differences in appearance
between males and females of the same

species. The great green macaw is very
similar in appearance to the military
macaw, but the military macaw has
more prominent blue coloring on its
hind neck, has darker plumage, and is
smaller. These two species are also
separated geographically.
Range, Observations, and Population
Estimates
The great green macaw is patchily
distributed in a 100,000-km2 (38,610mi2) area (BLI 2014b, p. 2). In addition
to occupying humid tropical forests
primarily in Central America (Costa
Rica, Honduras, Nicaragua, and
Panama), there are small remnant
populations in western Ecuador, as well
as northern Colombia (Berg et al. 2007,
p. 1; Chassot et al. 2006, p. 7). Although
there may be some interaction between
populations, the great green macaw is
fragmented into seven isolated
populations throughout its distribution
due to habitat loss (Monge et al. 2009,
pp. 159, 174).
Deforestation has reduced this
species’ habitat and concentrated its
population into primarily five areas: the
border of Honduras and Nicaragua, the
border of Nicaragua and Costa Rica, the
´
Darien region of Panama and Colombia,
and two very small populations in
Ecuador (Hardman 2011, p. 8; Monge et
al. 2009, p. 159).
Population estimates were made in
the 1990s and early 2000s. In 1993, the
population estimate was 5,000
individuals; in 2000, the population was
estimated to be between 2,500 and
10,000 birds (BirdLife International
´
2014b, p. 4; Rodrıguez-Mahecha 2002a).
The global population is now likely less
than 2,500 mature individuals (or less
than 3,700 with juveniles included)
(Monge et al. 2009, pp. 213, 256);
however, the actual population is far
from clear. Although historical
observations are useful for assessing the
range of the species, they may also be
biased because surveys may not have
sampled randomly. Thus, historical
population estimates of this species may
not be accurate. Although the
population in Costa Rica is increasing,
the population continues to be very
small (Monge et al. 2010, p. 16), and
researchers believe that the global
population of this species is decreasing
´
(Botero-Delgadillo and Paez 2011, p.
91). Specific information about the
range and population estimate for each
country is discussed below.
E:\FR\FM\02OCR3.SGM

Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
Historically in Colombia, it was found
´
in the north of the Serranıa de
´
Baudo,the West Andes, and east of the
´
upper Sinu valley (Snyder et al. 2000,
pp. 121–123). In the late 1990s, this
´
species was observed in Los Katıos
´
National Park, around Utrıa National
´
´
Park in Serranıa de Baudo (Salaman in
´
litt. 1997), and the Choco area of
western Colombia (Angehr in litt. 1996
in Snyder et al. 2000, pp. 121–123;
Ridgley 1982). This species’ potential
geographical range is 51,777 km2
(19,991 mi2), which includes two core
areas in Sierra Nevada de Santa Marta
and in the center of Antioquia
Department of Columbia (Salaman et al.
2009, p. 21; Monge et al. 2009,
unpaginated; Quevado-Gill et al. 2006,
p. 15). The total Columbian population
is currently unclear but it is now
´
believed to primarily exist in Los Katıos
´
National Park, which borders the Darien
region in Panama. It was also recently
observed in the area of Sabanalarga,
Antioquia (Quevado-Gill et al. 2006, p.
15). Even though the largest population
´
is thought to be in the northern Darien
border region with about 1,700 adults,
researchers believe this is an estimate
without a strong basis (Botero´
Delgadillo and Paez 2011, p. 91). The
populations in Colombia are highly
localized, and this number could be an
overestimate (Botero-Delgadillo and
´
Paez 2011, p. 91).
Costa Rica
The great green macaw historically
inhabited forests along the Caribbean
lowlands of Costa Rica (Chosset et al.
2004, p. 32). The population has
increased in that area since 1994, when
there was an estimate of 210 birds. The
population appears to have fluctuated;
in 2004, it was estimated that a
maximum of 35 pairs were breeding in
northern Costa Rica (Chosset et al. 2004,
p. 32). A survey conducted in 2009
reported a population estimate of 302 in
Costa Rica (Monge et al. 2009, p. 12);
another estimate was that there was a
total of 275 birds in Costa Rica in 2010
(Chassot 2010 pers. comm. in Hardman
2011, p. 11).
Approximately 67,000 ha (165,561 ac)
of great green macaw breeding territory
now remains in Costa Rica (Chun 2008,
p. v), which is less than 10 percent of
its original suitable habitat (Monge et al.
2010, p. 15; Chosset et al. 2004, p. 38).
Potential great green macaw breeding
habitat, excluding Ecuador, is defined
by the density of almendro trees, which
this species uses for its primary feeding
and nesting substrate. Almendro trees
are found only on the Atlantic coast
from southern Nicaragua down through
Costa Rica and Panama and into
Colombia, primarily at altitudes below
900 m (2,953 ft). Based on the

assumption that great green macaw
breeding pairs require 550 ha (1,359 ac)
of non-overlapping habitat, Chun
postulated that northern Costa Rica
could support about 120 breeding pairs
(2008, p. 110). Chun notes that even the
forested areas identified as individual
‘‘patches’’ through a geographic
information system (GIS) program do
not necessarily represent areas of forest
with continuous canopy cover
(indicating complex, fairly undisturbed
habitat that is likely to contain
nutritional needs for this species).
Although these patches of forest are
technically connected at some level,
they are for the most part highly porous
and discontinuous, and no analysis was
performed to filter out stands that might
be porous or discontinuous. There are
some areas in its potential range that are
above the elevation threshold for
almendro trees, and do not meet the
criteria for suitable habitat.
Ecuador
In Ecuador, there may only be one
viable population. This population
exists in the Cerro Blanco Protected
Forest, which is 6,070 ha (15,000 ac)
outside of Guayaquil in Guayas
Province (Villate et al. 2008, p. 19). This
population is believed to be
approximately 10 individuals. An
overall estimate of 60 to 90 individuals
in Ecuador in 2011 may be optimistic
(Horstman pers. comm. in Hardman

Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
asabaliauskas on DSK5VPTVN1PROD with RULES
2011, p. 12). Ecuador’s population in
2002 was estimated to be between 60
and 90 individuals (Monge et al. 2009,
p. 256), but the population was reported
to be rapidly decreasing. In addition,
this is a decline from 1995, when the
population was estimated to be
approximately 100 birds in Esmeraldas
Province alone (Waugh 1995, p. 10).
Between 1995 and 1998, some
individuals were observed in the Playa
de Oro area along the Santiago River
(Jahn 2001, pp. 41–43). In 2005, the
species was described as being found in
scattered forest remnants in coastal
Ecuador from Guayas to Esmeraldas
Province (Horstman 2005, p. 3).
In addition to the small population in
the Cerro Blanco Protected Forest,
recently reported to be about 10
individuals, there may be another small
group in the Rio Canande Reserve,
which is a humid tropical forest and is
located in the Esmeraldas province in
coastal northern Ecuador (Horstman
pers. comm. in Hardman 2011, p. 12).
Rio Canande Reserve (1,813 ha or 4,478
ac) is one of eight reserves managed by
another NGO, the Jocotoco Foundation.
The most recent population census in
Ecuador was conducted in the provinces
of Esmeraldas, Santa Elena, and Guayas.
Five individuals were recently observed
´
in the Bosque Protector Chongon
Colonche; one macaw was observed at
the Hacienda El Molino, near the Cerro
Blanco Protected Forest; and two
macaws were seen at Rio Canande
(Horstman 2011, p. 16). The Cordillera
´
(mountain range) de Chongon-Colonche
is on the central pacific coast of
Ecuador, located in the provinces of
Guayas and Manabi. Some individual
great green macaws have also been
observed at Hacienda Gonzalez 40 km
(25 mi) northwest of Guayaquil;
however, these individuals may be part
of the same population found in Cerro
Blanco. In summary, the majority of
individuals are believed to be in
Esmeraldas Province, and very small
´
numbers remain in the ChongonColonche mountain range, Guayas.
Honduras
In 1983, the great green macaw was
common in lowland rain forests in the
Moskitia (Mosquitia) area and eastern
Olancho (Marcus 1983, p. 623). The
region known as the Moskitia includes
both eastern Honduras and northern
Nicaragua. Historically, the species was
reported to occur in the areas of
Juticalpa and Catacamas in Olancho
(Marcus 1983, p. 623). The species was
´
observed daily in the Platano River area
in flocks of more than 10 individuals
and almost daily in the Patuca River
area, usually in pairs (Barborak 1997 in
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
Snyder et al. 2000, pp. 121–123). In
August 1992, macaws were recorded on
the Patuca River at Pimienta upstream
from Wampusirpe (Wiendenfeld in
Monge et al. 2009, p. 242). Currently,
´
this species exists in the Rio Platano
Biosphere Reserve (800,000 ha or
1,976,843 ac), which has been described
as one of the most important reserves in
Central America (Anderson et al. 2004,
p. 447).
Nicaragua
In Nicaragua, the great green macaw
is found primarily in lowland, tropical,
and rain forest, as well as pine barrens,
primarily in the Bosawas Reserve in the
´
north and around the Indio-Maız and
San Juan rivers in the south (Stocks et
´
´
al. 2007, p. 1503; Martinez-Sanchez
2007; Chassot 2004, p. 36). The name
Bosawas is derived from three
significant geographic landmarks that
delineate the reserve’s core zone limits:
The Bocay River, Mount Saslaya, and
the Waspuk River. The Bosawas
protected area contains habitat that is
vital to the species. In the buffer zone
´
of the Indio-Maız Biological Reserve,
great green macaw nesting locations
´
have been identified. The Indio-Maız
Biological Reserve is located in
Nicaragua just across the San Juan River
at the northern border of Costa Rica, and
is nearly 264,000 ha (652,358 ac) in size.
The Nicaragua and Costa Rica macaw
populations intermix; macaws have
been observed crossing the San Juan
River, which separates Nicaragua and
Costa Rica. As of 2006, in the Quezada,
Bijagua, Samaria, and La Juana
communities, five macaw nests had
been located during surveying. As of
2010, 35 active nests had been
´
documented in the Indio-Maız
Biological Reserve (Monge et al. 2010, p.
16).
In 1999, Powell et al. estimated that
the Nicaraguan great green macaw
population could be 10 times the size of
the population in Costa Rica. In 2008, a
population viability analysis was
conducted that indicated the size of the
great green macaw population in
Nicaragua was 661 individuals (Monge
et al. 2010, p. 21). In 2009, a population
census was conducted, during which
432 macaws were observed. The
researchers suggest that the ‘‘average
population’’ in Nicaragua is 532 (Monge
et al. 2010, p. 13). This 2009 study
yielded an estimated population of 834
individuals in Costa Rica and Nicaragua
combined (Monge et al. 2010, p. 21).
Panama
In Panama, the great green macaw is
believed to inhabit the following areas:
Bocas del Toro, La Amistad, northern
PO 00000
Frm 00026
Fmt 4701
Sfmt 4700
´
Veraguas, Colon, San Blas, Darien, and
Veraguas South (Monge et al. 2009,
unpaginated). The species has been
described as locally fairly common near
Cana, Alturas de Nique, in 2005 (Angehr
in litt. 2005). As of 2009, the historical
distribution in Panama was described as
not well known due to lack of
information (Monge et al. 2009, p. 68).
The most viable population is believed
´
to be in Darien National Park, Panama,
which borders Colombia (Monge et al.
2009, p. 68; Angehr in litt. 1996 in
Snyder et al. 2000, pp. 121–123; Ridgley
´
1982). Researchers believe the Darien
area may contain the largest overall
population of the great green macaw.
However, there is little recent
information to confirm this (Monge et
´
al. 2009, p. 68). Darien National Park is
the largest national park in Panama, and
one of the largest tropical forest
protected areas in Central America (The
Nature Conservancy (TNC) 2011, p. 1).
´
The Darien region encompasses nearly
809,371 ha (2 million acres) of protected
´
areas, including Darien National Park
˜
and Biosphere Reserve, Punta Patino
Natural Reserve, Brage Biological
Corridor, and two indigenous reserves
(TNC 2011, p. 1). La Amistad, an area
that may have a fairly viable population,
connects suitable habitat in Panama
´
such as Cerro Punta, Rio Platano, and
´
the Darien region, and connects the
remote hills of Bocas del Toro Province
with habitat in Costa Rica. La Amistad
is approximately 200,000 ha (500,000
acres) in area.
Summary of Population Estimate
The global population of great green
macaws is estimated to be between
2,500 and 3,700 mature individuals (BLI
2014b, p. 4; Chassot and Arias 2012, p.
61; Monge et al. 2009, p. 213; Jahn in
litt. 2005, 2007, unpaginated). Based on
the best available information from
experts, the total population is likely
between 1,000 and 3,000 individuals
´
(Botero-Delgadillo and Paez 2011, p. 91;
Monge et al. 2009, p. 213; Monge et al.
2009b, p. 68). In Ecuador, the
population is estimated to be between
30–40 individuals (Horstman in litt in
BLI 2014, p. 3). In 2009, a census was
conducted in Costa Rica and Nicaragua
(Monge et al. 2010, p. 13). A total of 173
individuals were observed in the Costa
Rican study area, and 432 individuals
were observed in the Nicaraguan study
area during the breeding season (Monge
et al. 2010, p. 22), with the areas of
´
Monico, Romerito, and Bartola having
the highest estimated abundance at the
time of each census. The population of
the great green macaw for Costa Rica is
currently estimated to be approximately
302 individuals, and the population for

asabaliauskas on DSK5VPTVN1PROD with RULES
Nicaragua is roughly estimated to be 834
individuals (Monge et al. 2010, p. 22).
Species with strict habitat requirements
such as the great green macaw are
particularly subject to population size
overestimation, because they are
unlikely to be present in suboptimal
habitat despite those habitats being
included as part of the species range
(Jetz et al. 2008, p. 116–117). Thus,
additional surveys are needed, and
ground-truthing (gathering data
regarding where the species is located)
is essential to obtain accurate
population estimates for this species.
Habitat and Life History
The great green macaw inhabits
humid lowland foothills and deciduous
forests generally below 600 m (1,968 ft),
but also may occur between 1,000 and
1,500 m (3,281 and 4,921 ft) depending
on suitable habitat, which is primarily
based on the presence of almendro
(Dipteryx panamensis) trees. The type of
habitat preferred by the great green
macaw is an ecosystem where the
almendro tree and Pentacletra
macroloba (oil bean tree) dominate
(Chassot et al. 2006, p. 35). This species’
nests have been found in Carapa
nicaraguensis (caobilla), Enterolobium
schomburgkii (guanacaste blanco),
Goethalsia meiantha, Prioria copaifera
(cativo), and Vochysia ferruginea
(botarrama) trees (Chosset and Arias
2010, p. 14; Powell et al. 1999). Nests
have been observed in large trees, with
cavities that are nearly 20 m (66 ft)
above ground (Rodriguez-Mahecha
2002, p. 119). Great green macaws have
been observed to use the same nesting
cavity for many years if they are
undisturbed, although they may
alternate nest sites each year (Chun
2008, p. 102). Reproductive capability is
generally reached between ages 5 and 6
years (Chassot et al. 2004, p. 34). The
great green macaw mates for life, and
nests in deep cavities (usually of
almendro trees) from December to June
(Chassot et al. in Villate et al. 2008, p.
19; Monge et al. 2002, p. 39). The
incubation time is 26 days and the
nesting period is 12 to 13 weeks
(Rodriguez-Mahecha et al. 2002, p. 119).
After the breeding season, individuals
disperse from the lowlands to higher
forests in the mountains in search of
food (Powell et al. 1999 in Chosset et al.
2004, p. 38).
The great green macaw has been
observed in flocks of up to 18
individuals, and has been observed
traveling long distances on the
Caribbean slope. Macaws are strong
fliers and are known to travel hundreds
of kilometers (Chosset and Arias 2010,
p. 5; Chosett et al. 2004, p. 36). During
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
a study in the late 1990s, macaws fitted
with radio transmitters demonstrated
that macaws migrate seasonally based
on food availability, and were found to
travel between 40 and 58 km (25 to 36
mi) while in search of food (Chosset et
al. 2004, p. 35).
Diet
The great green macaw has been
observed feeding on fruits of 37 tree
species (Berg et al. 2007, p. 2; Chassot
et al. 2006, p. 35). While it is closely
associated with the almendro tree, its
diet varies based on location. In
Ecuador, it was observed feeding on the
following tree species: Cordia
eriostigma (totumbo), Cynometra sp.
(cocobolo), Ficus trigunata (matapalo),

Ficus sp. (higueron), Psidium
acutangulum (Guayaba de monte),
Chrysophyllum caimito (caimito), and
Vitex gigantea (tillo blanco or pechiche)
(Berg et al. 2007, p. 2; Waugh 1995, p.
7). In other parts of its range, it has also
been observed feeding on Cavanillesia
platanifolia (NCN), Cecropia litoralis
(pumpwood or trumpet tree),
Centrolobium ochroxylum (amarillo de
guayaquil), Cochlospermum vitifolium
(buttercup tree), Lecythis ampla
(sapucaia), Leucaena trichodes (NCN),
Odroma pyramidalis (NCN),
Pseudobombax guayasen (NCN),
Pseudobombax millei (beldaco), Rafia
species (believed to be palms), Sloanea
spp., Symphonia globulifera (NCN), and
Terminalia valverdeae (guarapo) (Berg
et al. 2007, p. 6). One preferred plant
species, Cynometra bauhiniifolia (NCN),
produced more food than nine other
species (Berg et al. 2007, p. 1). In
another study, two of the most
important sources of food for the great
green macaw, in addition to the
almendro tree, were found to be
Sacoglottis trichogyna (titor, rosita, or
manteco) and Vochysia ferruginea
(NCN) (Herrero-Fernandez 2006, p. 9;
Chassot et al. 2006, p. 35). S. trichogyna
fruits were observed to be its preferred
food when D. panamensis was scarce or
unavailable in Costa Rica (Chassot et al.
2004, p. 34).
Almendro Trees
The great green macaw is closely
associated with almendro trees
(Dipteryx panamensis) for feeding and
nesting in the majority of its range
(Chun 2008, p. iv; Chosset et al. 2004,
p. 34). Because the great green macaw
is highly dependent on the almendro
tree, we are describing almendro tree
habitat, its life history, and factors that
affect its habitat. The almendro tree
(also known as the tropical almond or
mountain almond tree) is a member of
the pea family (Fabaceae;
PO 00000
Frm 00027
Fmt 4701
Sfmt 4700

Papilionoideae) and bears compact,
single-seeded drupes. The seeds are
encased in a thick woody endocarp that
has been observed to persist on the
forest floor for up to 2 years (Hanson
2006, p. 68). This tree species is only
located in southern Nicaragua, Costa
Rica, Panama, and Colombia, where it
grows primarily in the lowlands of the
Atlantic plains. They require an annual
rainfall of 3 to 5 m (approximately 10
to 16 ft) (Schmidt 2009, p. 14) for
optimal growth. A 2008 study reported
that nearly 90 percent of all great green
macaw nests identified in northern
Costa Rica are located within hollowed
cavities of large almendro trees (Chun
2008, p. 109). Additionally, almendro
trees were found to provide 80 to 90
percent of both the macaw’s food and
nesting needs. Great green macaw pairs
tend to select nesting trees that are
surrounded by relatively dense stands of
reproducing almendro trees (Chun
2008). Almendro tree fruit sustains the
adults, chicks, nestlings, and fledglings
over the course of the breeding and
development season, which coincides
with the peak production of almendro
fruit (November through March).
Likely pollinators of the almendro
tree are bees within the genera Bombus,
Centris, Melipona, Trigona, and
Epicharis (Thiele 2002 in Hanson 2006,
p. 3; Flores 1992, pp. 1–22; Perry et al.
1980, p. 310). These trees are referred to
as ‘‘emergent’’ because they are the
tallest trees in the forest. Almendro trees
can grow to over 46 m (150 ft) and reach
a diameter of 1.5 m (4.92 ft). Three
hundred-year-old trees have been
documented, but research suggests that
the almendro tree has a maximum
potential age of 654 years (Fichtler et al.
2003 in Schmidt 2009, p. 15).
Wood from the almendro tree is
heavy, commercially valuable, and
yields the highest prices on local
markets (Rodriguez and Chaves 2008, p.
5). It is used for furniture, floorings,
bridges, railroad ties, boats, marine
construction, handicrafts, veneers,
industrial machinery, sporting
equipment, springboards, and
agricultural tool handles (Schmidt 2009,
p. 16). Almendro outsells every other
tree species on the Costa Rican timber
market (Grethel and Norman 2009 in
Schmidt 2009, p. 77; Rodriguez and
Chaves 2008, p. 5). It was listed in
Appendix III of CITES by Costa Rica in
2003 and by Nicaragua in 2007 (https://
www.cites.org). A species is unilaterally
listed in Appendix III by a country in
the native range of that species, at the
request of that country. Article II,
paragraph 3, of CITES states that
‘‘Appendix III shall include all species
which any Party identifies as being
E:\FR\FM\02OCR3.SGM

asabaliauskas on DSK5VPTVN1PROD with RULES
60002
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
subject to regulation within its
jurisdiction for the purpose of
preventing or restricting exploitation,
and as needing the cooperation of other
parties in the control of trade.’’ For the
export of specimens of an Appendix-III
species from a country that has listed
the species, the Management Authority
in that country of export needs to
determine that the specimens were not
obtained in contravention of that
country’s laws. In addition to CITES
protections, a recent decision by the
fourth Chamber of Costa Rica’s Supreme
Court in 2008 required the Ministry of
Environment and Energy (MINAE, or
Ministerio de Ambiente y Energia) to
abstain from the use, exploitation, or
extraction of almendro trees (Chun
2008, p. 113).
Recent research found that this tree
species is much more restricted to
lowland habitat than previously
described; it is predicted to occur
between 45 and 125 m (147 to 410 ft)
in elevation, in part based on its soil
requirements (Schmidt 2009, p. iv;
Chun 2008, p. 109). The almendro tree
is best adapted to areas with high levels
of rainfall and acidic clay soils with
good drainage below elevations of 500
m (1,640 ft) such as the Atlantic
lowlands of Costa Rica (Schmidt 2009,
p. iv). Almendro trees require at least
2,000 millimeters (mm) (79 inches) of
rainfall per year for optimal growth
(Schmidt 2009, p. 69).
Great green macaw breeding pairs are
believed to require a home range of 550
ha (1,359 ac) (Chun 2008, p. 105).
Because the great green macaw requires
such a large range, and is strongly
associated with almendro trees, range
countries such as Nicaragua and Costa
Rica have developed conservation plans
for the almendro tree. Almendro trees
commonly occur at a density of less
than one adult tree per hectare (Hanson
et al. 2008 in Schmidt 2009, p. 14;
Hanson et al. 2006, p. 49). The highest
density recorded was 4 trees per hectare
´
(Chaverri and Lopez 1998). In one area
of Costa Rica that was surveyed for
almendro trees, of 140,178 ha (56,728
ac) surveyed, 20 percent exhibited
densities of 0.50 almendro trees per
hectare or more, and 50 percent had
densities of 0.20 trees per ha or more
(Chun 2008, p. 103).
Due to their important role in the
ecosystem, particularly with respect to
the great green macaw, conservation
efforts have focused on the almendro
tree. These trees not only provide
habitat to many wildlife species such as
the great green macaw, but they also
play a significant role in the ecosystem.
One conservation strategy for the great
green macaw is to protect 30,159 ha
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
(74,493 acres) of primary, secondary,
and mangrove forest that remains in this
species’ nesting habitat. Another
conservation strategy has been to
establish almendro tree plantations. Due
to its open crown structure, almendro
has a relatively translucent canopy that
produces only moderate shade, which
allows for the production of shade
canopy crops such as pineapple and
cacao (Schmidt 2009, p. 19). These
almendro plantations are being
researched for several reasons,
particularly due to the almendro tree’s
ability to resist decay, its ability to
capture carbon dioxide, and its role in
the ecosystem (Schmidt 2009, p. 11).
Additionally, almendro trees have been
identified as the most promising species
for long-term carbon sink reforestation
projects in Costa Rica (Redondo-Brenes
2007, p. 253; Redondo-Brenes and
Montagnini 2006, p. 168).
In Ecuador, the great green macaw is
not dependant on almendro trees,
although it still inhabits humid lowland
areas (Juniper and Parr 1998, p. 424). In
this habitat, the great green macaw
prefers Lecythis ampla (salero) in the
Esmeraldas rainforest, Cynometra
bauhiniaefolia (cocobolo) as a primary
food source, and pigio (Cavanillesia
platanifolia) as a nest tree (Chassot et al
2007, p. 1; Berg et al 2007, pp. 1–3).
Conservation Status
There are various protections in place
for the great green macaw at the
international, national, and local levels.
At the international level, this species is
listed as endangered on the IUCN Red
List due to continuous loss of habitat,
hunting, and poaching of this species
for the pet trade (BLI 2013). IUCN’s Red
List classifies species as endangered
(extinction probability of 20 percent
within 20 years) or critically endangered
(extinction probability of 50 percent
within 10 years) based on several
criteria, including limited or declining
ranges or populations. However, the
status under IUCN conveys no actual
protections. This species is listed in
Appendix I of CITES. Appendix I
includes species threatened with
extinction that are or may be affected by
international trade, and are generally
prohibited from commercial trade. Refer
to the discussion above for the military
macaw for additional information about
CITES. The great green macaw’s
conservation status in each country is
discussed below and in more detail
under Factor D.
Colombia
The great green macaw is listed as
Vulnerable on Colombia’s Red List
(Renjifo et al. 2002, p. 524). It has
PO 00000
Frm 00028

´
protected status in Los Katıos National
´
Park, Utrıa National Park, Paramillo
National Park, and Farallones de Cali
National Natural Park (Rodriguez et al.
2002, pp. 120–121). The largest
population of the great green macaw is
´
believed to exist in the Darien Endemic
Bird Area (EBA) 023, which
´
encompasses southern Panama and
northwestern Colombia. However, there
are no reliable population estimates for
´
this area (Botero-Delgadillo and Paez
2011, p. 91; Jahn in litt. 2004). Colombia
developed a National Action Plan for
the Conservation of Threatened Parrots
´
(Plan Nacional de Accion para la
´
Conservacion de los Loros
Amenazados), which was in effect until
2007. The ProAves Foundation, an NGO
in Colombia, has been active in parrot
conservation since 2005. Other than
NGO involvement, it is unclear what
proactive, effective protections are in
place for this species.
Costa Rica
The great green macaw is considered
to be endangered in Costa Rica (Monge
et al. 2010, p. 22; Herrero 2006, p. 6;
Executive Order No. 26435–MINAE).
Several intense conservation initiatives
are underway for this species in Costa
Rica. In 2001, a committee was formed
to investigate a corridor for the
conservation of this species’ habitat. As
a result, the San Juan-La Selva
Biological Corridor was formed to
´
connect the Indio Maız Biological
Reserve in southeastern Nicaragua with
the Central Volcanic Cordillera Range in
Costa Rica. This links Costa Rica’s La
Selva Biological Station in the north to
the Barra del Colorado Wildlife Reserve
and National Park and Protective Zone
of Tortuguero on Costa Rica’s Caribbean
coast. In addition, the conservation team
lobbied for the establishment of the
Maquenque National Wildlife Refuge to
protect the macaw’s breeding habitat
(Hardman 2011, p. 10; Chun 2008, p.
98). This corridor makes up a part of the
larger MesoAmerican Biological
Corridor, which has been proposed to
connect protected habitat from the
Yucatan Region in southern Mexico and
´
Belize to the Darien National Park in
Panama (https://
www.greatgreenmacaw.org/
BiologicalCorridor.htm, accessed
October 25, 2011).
The San Juan-La Selva binational
corridor links existing protected wild
areas. There is also an extended part to
the northwest that includes the El
Castillo area. The goal of this initiative
is to provide linkages to 29 protected
areas involving 1,311,182 ha (3,240,001
ac) (Chassot et al. 2006, p. 85). Because
macaws are known to move hundreds of

kilometers (Chosset and Arias 2010, p.
5), these linkages should allow this
species better access to different habitats
so that it is able to meet its nutritional
and nesting requirements. In addition to
containing key conservation sites for the
great green macaw, the corridor
connects the vast expanse that includes
Punta Gorda Natural Reserve, Cerro
Silva Natural Reserve, and Fortaleza
´
´
Inmaculada Concepcion de Marıa
Historic Monument (Chassot et al. 2006,
p. 85). The corridor also provides
connections among unprotected forest
patches in Costa Rica in addition to
providing connections to protected
areas. Many of these areas may not be
pristine habitat; some areas are either
inhabited by humans or used by local
communities to extract resources.
However, there are conservation
awareness programs in place throughout
the corridor, and the great green macaw
is being intensely managed and
monitored in the San Juan–La Selva
Biological Corridor.

Ecuador
This species is categorized as
critically endangered in Ecuador
(Monge et al. 2009, p. 256), primarily
due to deforestation and hunting
pressures. In Ecuador, the only
potentially population is believed to
exist in the Cerro Blanco Protected
Forest, which is 6,070 ha (15,000 ac) in
size. The Guayaquil subspecies of the
great green macaw (Ara a.
guyaquilensis) is thought to be in
imminent danger of extinction (Berg
2007, p. 1). In 2008, the National
Preservation Strategy for the Great
Green Macaw in Ecuador was described
at the Great Green Macaw Population
Viability Assessment and Habitat
Conservation Workshop held in Costa
Rica; however, funding is still lacking
for many of the initiatives in Ecuador
that have been prescribed as necessary
for the conservation of this species.
Honduras
The great green macaw is categorized
as endangered in Honduras (List of
Wildlife Species of Special Concern,
Resolution No. Gg–003–98 APVS). In
1990, the Government of Honduras
prohibited the capture and sale of
wildlife, including the great green
macaw in Honduras. Currently, this
´
species exists in the Rio Platano
Biosphere Reserve (which consists of
800,000 ha or 1,976,843 ac). The official
designation of the Biosphere as a reserve
is to protect and conserve biodiversity;
however, this designation has not halted
deforestation within the protected area
(UNESCO 2011, p. 1; ParksWatch 2011;
Wade 2007, p. 65). Additionally, as of
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
2009, there were 23 areas in Honduras
identified as Important Bird Areas
(IBAs) (Devenish et al. 2009, p. 1) that
may provide additional protections to
this species in part by serving as
ecotourism sites that can increase
conservation efforts in the areas. For
additional information on IBAs, see the
discussion above for the military
macaw.
Nicaragua
Nicaragua follows the IUCN
categorization of endangered for this
species (Castellon 2008, pp. 13, 19;
´
Lezama-Lopez 2006, p. 90). The great
´
green macaw exists in the Indio-Maız
Biological Reserve, which has had
protected status since 1990, although
threats to the species still exist in this
Reserve (Herrera 2004, pp. 5–6).
Nicaragua is also participating in the binational conservation strategy for this
species (Monge et al. 2009, pp. 11, 16).
Panama
There is little information available
regarding the status of this species in
Panama (Monge et al. 2009, p. 67);
however, Panama follows the IUCN
categorization for this species (Devenish
et al. 2009, p. 294). The great green
´
macaw is believed to be in Darien
National Park (Monge et al. 2009, p. 68).
Panama’s wildlife law of 1995, Law No.
24, establishes the standards for wildlife
conservation.
NGO Involvement
There are many nongovernmental
organization (NGO), private, and
government efforts to protect this
species, although not all of the projects
and NGOs are identified in this
document. NGOs have conducted
collaborative efforts, such as training
workshops, that are community-focused
and aimed at the conservation of the
´
habitat. In Nicaragua, Fundacion
Cocibolca is active in this species’
conservation. This NGO first signed an
agreement with Nicaragua’s Natural
Resources Ministry (MARENA) in 1996,
at which time the conservation group
was the first NGO to have been granted
responsibility to manage a national
protected area in Nicaragua (https://
www.marena.gob.ni; accessed
November 9, 2011; https://
www.planeta.com, accessed November
9, 2011). The Nicaraguan conservation
´
organization, Fundacion del Rio, works
´
in the buffer zone of the Indio-Maız
Biological Reserve, which borders the
San Juan River (Villate 2008, p. 39). In
´
1999, Fundacion del Rio began an
environmental education program in
this buffer zone to promote awareness of
the great green macaw and its habitat. In
PO 00000
Frm 00029

another area, as a result of conservation
efforts, the local government of El
Castillo declared this species the official
municipal bird, and the city established
sanctions to those intending to harm
this species (Chassot et al. 2008, p. 23).
´
´
Since 2001, Fundacion del Rıo and
the Tropical Science Center in Costa
Rica have coordinated a binational
campaign focused on promoting the
awareness of the ecology of the great
green macaw in the lowlands of the San
Juan River area (Chassot et al. 2009, p.
9). Between 2002 and 2005, at least 11
workshops on great green macaw
biology and preservation were held
within communities of the buffer zone
of Indio-Maiz Biological Reserve in
Costa Rica (Chassot et al. 2006, p. 86).
Some examples of projects initiated by
NGOs include installation of nest boxes
to increase nest availability and
community heritage festivals that are
focused on the great green macaw. Some
NGOs are providing training to local
communities to monitor populations,
and some researchers are studying this
species via satellite transmitters to
determine the species’ home range and
specific habitat used (Chosset et al.
2004, p. 35). In Costa Rica and
Nicaragua, 20 communities are
participating in monitoring and
protection activities of the great green
macaw (Chosset and Arias 2010, p. 3).
The primary objectives of the campaign
have been to improve awareness by
conducting workshops on the
importance, threats, and conservation of
the great green macaw and its habitat; to
strengthen natural resources
management by environmental
authorities of both Nicaragua and Costa
Rica, focusing on the local and
international biological corridors; and to
organize joint activities (Chassot et al.
2006, p. 83).
In Colombia, the NGO ProAves has
made great progress in forming
partnerships at the local, regional, and
international levels to carry out bird
conservation initiatives (Chassot et al.
2008, p. 23; Quevado-Gill et al. 2006, p.
18). Additionally, reforestation efforts
have occurred (Monge et al. 2009, p.
263). These efforts have focused
primarily within the reserves of the
Colombian Civil Society Association
Network (Quevado-Gill et al. 2006, p.
17). Conservation efforts and these
workshops have been important because
they have trained the community in
sustainable development by linking
local agricultural activities to the
protection of natural resources
(Quevado-Gill et al. 2006, p. 17).
Three NGOs are active in the
conservation of this species in Ecuador:
Pro-Forest Foundation in Guayas

Province, Fundacion Natura, and the
Jocotoco Foundation at the Rio Canande
Reserve in Esmeraldas Province. The
´
Pro-Forest Foundation (Fundacion
ProBosque) was created in 1992,
through a decree of the Ecuadorian
Ministry of Agriculture. Its mission is to
protect areas with an emphasis in
reforestation, agroforestry, investigation,
environmental education, and
ecotourism programs, all in order to
support the conservation of biodiversity.
´
In Panama, the Asociacion Nacional
´
para la Conservacion de la Naturaleza
(ANCON) began conservation work in
1991. The project has jointly worked on
conservation efforts with Panama’s
Instituto Nacional de Recursos
Naturales Renovables (INRENARE).
ANCON has worked on training park
rangers, marking and patrolling paths
and park boundaries, acquiring property
around parks and tree nurseries, and
improving agricultural techniques (TNC
2011, p. 2).
Additionally, members from several
NGOs participated in the great green
macaw conservation workshop held in
2008. The purpose of the workshop was
to bring together experts, to determine
the priorities for the conservation of the
species, and to develop a plan for its
conservation (Monge et al. 2009, entire).
We acknowledge the substantial effort
under way by various NGOs in the range
countries of this species to protect it and
its habitat. Despite many efforts in
place, the populations of the great green
macaw continue to face many threats to
its habitat.
Evaluation of Threat Factors
asabaliauskas on DSK5VPTVN1PROD with RULES
Introduction
Section 4 of the ESA (16 U.S.C. 1533)
and implementing regulations (50 CFR
424) set forth procedures for adding
species to, removing species from, or
reclassifying species on the Federal List
of Endangered and Threatened Wildlife
and Plants. Under section 4(a)(1) of the
ESA, a species may be determined to be
endangered or threatened based on any
of the following five factors:
A. The present or threatened
destruction, modification, or
curtailment of its habitat or range;
B. Overutilization for commercial,
recreational, scientific, or educational
purposes;
C. Disease or predation;
D. The inadequacy of existing
regulatory mechanisms; and
E. Other natural or manmade factors
affecting its continued existence.
In making this finding, information
pertaining to the great green macaw in
relation to the five factors in section
4(a)(1) of the ESA is discussed below. In
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
considering what factors might
constitute threats to a species, we must
look beyond the exposure of the species
to a particular factor to evaluate whether
the species may respond to that factor
in a way that causes actual impacts to
the species. If there is exposure to a
factor and the species responds
negatively, the factor may be a threat,
and, during the status review, we
attempt to determine how significant a
threat it is. The identification of factors
that could impact a species negatively
may not be sufficient to compel a
finding that the species warrants listing.
The information must include evidence
sufficient to suggest that these factors,
singly or in combination, are operative
threats that act on the species to the
point that the species may meet the
definition of endangered or threatened
under the ESA.
This rule focuses primarily on where
this species has been documented,
which is generally in parks and other
areas with protected status and the
peripheral zones. In some cases, we will
evaluate the factor by country. In other
cases, we may evaluate the factor by a
broader region or context, for example,
if we do not have adequate information
specific to a particular country about
this species. This is because often
threats are the same or very similar
throughout the species’ range.
A. The Present or Threatened
Destruction, Modification, or
Curtailment of Its Habitat or Range
Throughout the range of this species,
the factors impacting the great green
macaw are generally very similar. The
main factors affecting this species are
habitat loss and degradation, and
poaching (McGinley et al. 2009, p. 11;
Berg et al. 2007; Chassot et al. 2006;
Quevado-Gill et al. 2006, p. 16; Guedes
2004, p. 280). Both Central and South
America continue to experience high
levels of deforestation (FAO 2010, p.
xvi). Habitat loss is primarily due to
conversion of the species’ habitat
(generally forests) to agriculture and
other forms that are not optimal for this
species (Chosset and Arias 2010, p. 3;
Monge et al. 2009, entire).
Almendro habitat, this species’
primary food and nesting source, has
declined significantly (Schmidt 2009, p.
16), particularly since the 1980s.
Almendro and other tree species used
by the great green macaw have been
selectively cut down and removed from
this species’ habitat. Selective logging is
the practice of removing one or two
generally large, mature trees and leaving
the rest. Throughout the range of the
great green macaw, its habitat has
declined primarily due to competition
PO 00000
Frm 00030
Fmt 4701
Sfmt 4700
for resources and human encroachment
´
(Guedes 2004, p. 279; Rodrıguez´
Mahecha and Hernandez-Camacho
2002; Chassot and Monge 2002 in
Rothman 2008, p. 509). Its habitat has
continuously been clear-cut and
converted to agriculture or human
establishments, which is discussed in
more detail below.
Logging
Tree species used by macaws tend to
be large, mature trees with large nesting
cavities. The practice of selective
logging often targets old, large trees that
macaws depend upon for nesting. In
selective logging, the most valuable
trees from a forest are commercially
extracted (Asner et al. 2005, p. 480;
Johns 1988, p. 31), and the forest is left
to regenerate naturally or with some
management until being subsequently
logged again. Johns (1988, p. 31),
looking at a West Malaysian dipterocarp
forest, found that mechanized selective
logging in tropical rainforests, which
usually removes a small percentage of
timber trees, causes severe incidental
damage. He found that the extraction of
3.3 percent of trees destroyed 50.9
percent of the forest. Selective logging
can cause widespread collateral damage
to remaining trees, subcanopy
vegetation, and soil, and the practice
impacts hydrological processes, erosion,
fire, carbon storage, and plant and
animal species (Chomitz et al. 2007, pp.
117, 119; Asner et al. 2005, p. 480).
Forests that were selectively logged 15
years prior became an open forest with
skeletons of incidentally killed trees,
serious gulley erosion, and vegetation
on waterlogged sites that had been
compacted by heavy vehicles (Edwards
1993, p. 9). Additionally, the
availability of food sources for
frugivores (fruit-eaters, such as the great
green macaw) is reduced because the
trees that contain nutritional sources are
no longer there.
Selective logging is particularly
devastating to the almendro tree, which
is slow growing and may take centuries
to reach sufficient size to harbor cavities
(Schmidt 2009, p. 15), and which great
green macaws need for both food and
shelter. The almendro tree’s wood is of
great commercial value due to its
strength and durability for flooring,
roofing, and irrigation systems (MadrizVargas 2004, p. 8). Concern for this tree
species was significant enough that the
species was listed as CITES Appendix
III by both Costa Rica and Nicaragua.
Listing species in Appendix III
enhances conservation measures
enacted for the species by regulating
international trade in the species. In
general, shipments containing CITES-
E:\FR\FM\02OCR3.SGM
02OCR3
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
listed species receive greater scrutiny
from border officials in both the
exporting and importing countries. The
elimination of almendro trees is
possibly the most severe threat for the
species in its range countries with the
exception of Ecuador, where the
decrease in availability of other tree
species used by the great green macaw
is a concern.
Although the nest cavities that the
macaws prefer (deep and dry) may take
10 to 20 years to form, the nests
themselves can last for several decades
(Chun 2008, p. 101). Even in
undisturbed forests, suitable tree
cavities are usually limited. As a result,
each loss of a nest site can represent the
loss of potentially many future chicks
that could have been raised in each tree
cavity.

Agriculture
Habitat degradation, particularly due
to conversion of forest habitat to
agriculture or plantations, is a major
factor affecting great green macaws. The
clearing of forests and buffer zones for
the development of plantations for
bananas, oil palms, cacao, coffee,
soybeans, and rice destroys great green
macaw nesting sites and exposes chicks
to poaching for the pet trade (Botero et
al. 2011, p. 92; Monge et al. 2009, pp.
26, 29, 43, 54; Waugh 1995, p. 2). By
2005, the world’s tropical forest biomes
had decreased to less than 50 percent
tree cover (Donald et al. 2010, p. 26), in
part due to the above activities. Tropical
forest fragmentation due to these
activities continues to be a concern. A
discussion of habitat loss and
degradation for each country follows.
Colombia
Very little information is available
about the great green macaw’s status in
´
Colombia (Botero-Delgadillo and Paez
2011, pp. 86, 90; Monge et al. 2009; Jahn
in litt. 2004). A large population is
´
believed to exist in Los Katıos National
Park, which borders the swampy and
´
sparsely populated Darien region in
Panama; however, there are no recent
reported observations of the species in
this area. Population surveys need to be
conducted (Botero-Delgadillo et al.
2011, pp. 88, 90; Monge et al. 2009). At
least 40 percent of the great green
macaw’s original distribution area in
northwestern Colombia was deforested
by 1997 (Etter 1998 in Jahn in litt. 2004).
Threats to this species in Colombia have
been identified as: Agriculture
(particularly illegal coca cultivation),
agroindustrial farms, large forest
plantings of exotic trees, wood
extraction, development of
infrastructure, and hunting, capturing,
VerDate Sep<11>2014

Jkt 238001
and harvesting of this species (Botero´
Delgadillo and Paez 2011, pp. 91–92).
´
Threats specific to Los Katıos National
Park are illegal deforestation and
hunting (UNEP–WCMC 2009, p. 1). In
2009, the threats in this park were so
severe that the park was added to
UNESCO’s List of World Heritage Sites
in Danger (https://whc.unesco.org/en/
list/711, accessed January 17, 2012).
Deforestation
Colombia has experienced extensive
deforestation in the last half of the 20th
century as a result of habitat conversion
for human settlements, road building,
agriculture, and timber extraction (FAO
2010, p. 233; Armenteras et al. 2006, p.
354). A 23-year study, conducted from
1973 to 1996, found that these activities
reduced the amount of primary forest
cover in Colombia by approximately
3,605 ha (8,908 ac) annually,
representing a nearly one-third total loss
˜
of primary forest habitat (Vina et al.
2004, pp. 123–124). More than 70
percent of rural land of Colombia
located in former forestlands is now
devoted to cattle grazing (Etter and
McAlpine 2007, pp. 89–92). Beginning
in the 1980s, habitat loss increased
dramatically as a result of influxes of
people settling in formerly pristine areas
˜
(Perz et al. 2005, pp. 26–28; Vina et al.
2004, p. 124). More recent studies
indicate that the rate of habitat
destruction is accelerating (FAO 2010,
p. xvi). Between the years 1990 and
2005, Colombia lost approximately
52,800 ha (130,471 ac) of primary forest
annually (Butler 2006a, pp. 1–3).
Primary forest habitats such as those
used by the great green macaw
throughout Colombia have undergone
˜
extensive deforestation. Vina et al.
(2004, pp. 123–124) used satellite
imagery to analyze deforestation rates
and patterns along the ColombianEcuadorian border (in the Departments
of Putumayo and Sucumbios,
respectively) and found that between
1973 and 1996, a total of 829 km2 (320
mi2) of tropical forests within the study
area were converted to other uses. This
corresponds to a nearly one-third total
loss of primary forest habitat, or a nearly
2 percent mean annual rate of
deforestation within the study area.
Habitat loss and degradation, including
conversion of this species’ habitat to
other forms of use such as agriculture,
plantations, or harvesting of this
species’ plant food sources, continue to
occur and affect the quality of this
species’ habitat.
In addition to the direct detrimental
effect of habitat loss, there are several
indirect effects of habitat disturbance
and fragmentation, such as road
PO 00000
Frm 00031
Fmt 4701
Sfmt 4700
60005
building (Brooks and Strahl 2000, p. 10).
Roads increase human access into
habitat, facilitating further exploitation,
erosion, and habitat destruction
(Chomitz et al. 2007, p. 88; Hunter 1996,
pp. 158–159). Research has documented
that road building and other
infrastructure developments in areas
that were previously remote forested
areas have increased accessibility and
facilitated further habitat destruction
and human settlement (Etter et al. 2006,
´
´
p. 1; Alvarez 2005, p. 2,042; Cardenas
´
and Rodrıguez-Becerra 2004, pp. 125–
˜
130; Vina et al. 2004, pp. 118–119;
Hunter 1996, pp. 158–159). A study
conducted on the effects of habitat
fragmentation on Andean birds within
western Colombia determined that 31
percent of the historical bird
populations in western Colombia had
become extinct or locally extirpated by
1990, primarily as a result of habitat
fragmentation from deforestation and
human encroachment (Kattan and
´
Alvarez-Lopez 1996, p. 5; Kattan et al.
1994, p. 141). Greater exposure of soil
to direct sunlight leads to factors such
as drier soils and also creates a different
growing environment. For example, the
creation of roads changes the habitat by
altering the distance of nesting and
feeding habitat to the forest ‘‘edge,’’
increasing the amount of light exposure,
and creating stress on (breeding)
individuals in part due to noise and
´
´
visual stimuli (Benıtez-Lopez et al.
2010, p. 1,308).
Coca Cultivation
Ongoing coca cultivation has had a
significant impact on forest cover in
Colombia (Armenteras et al. 2006, p.
˚
355; Fjeldsa et al. 2005, p. 205; Page
´
2003, p. 2; Alvarez 2002, pp. 1,088–
1,093). Colombia is one of the leading
producers of coca, the plant species that
provides the main ingredient of cocaine.
Between 1998 and 2002, cultivation of
illicit crops increased by 21 percent
each year, with a parallel increase in
deforestation of formerly pristine areas
´
of approximately 60 percent (Alvarez
2002, pp. 1,088–1,093). Much of
Colombia’s coca is grown by farmers
because it generates more income than
any other crop (Butler 2006, pp. 1–2).
Illegal drug crops are cultivated within
the great green macaw’s range (BLI
2014b, p. 4). Large-scale coca
production has moved into the
´
extensive rainforests of the Choco state,
which is considered to be a biodiversity
hotspot in northwest Colombia and in
the range of the great green macaw.
A 1990 United Nations study
estimated that coca growers can make
about $4,000 U.S. dollars per hectare
(Tammen 1991, p. 12 in Page 2003, pp.
E:\FR\FM\02OCR3.SGM
02OCR3
asabaliauskas on DSK5VPTVN1PROD with RULES
60006
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
15–16). A farmer can only earn about
$600 per hectare growing an alternative
crop such as coffee, which is the most
often cited potential substitute crop for
coca (Page 2003, pp. 15–16). Page (2003,
pp. 15–16) notes that production of
coffee and tea requires 3 to 4 years from
planting to first harvest and then can
only be harvested once per year, while
coca can be harvested 8 months after it
is planted and can be harvested every 90
days thereafter. The coca bushes
themselves do not require much care
and can be cultivated on plots of land
that are much smaller than those
required for crops other than coca
(Tammen 1991, p. 6 in Page 2003, p.
16). Unfortunately, not only do coca
crops displace native habitat and
species assemblages that are important
for the great green macaw, but they also
deplete the soil of nutrients, which
hampers regeneration following
abandonment of fields (Van Schoik and
Schulberg 1993, p. 21).
Drug eradication efforts in Colombia
have further degraded and destroyed
primary forest habitat by using
nonspecific aerial herbicides to destroy
´
illegal crops (BLI 2007d, p. 3; Alvarez
´
´
2005, p. 2,042; Cardenas and Rodrıguez
Becerra 2004, p. 355; Oldham and
Massey 2002, pp. 9–12). For example, in
2006, eradication efforts were
undertaken on over 2,130 km2 (822 mi2)
of land, which included spraying of
1,720 km2 (664 mi2) and manual
eradication on the remaining land.
These eradication efforts occurred over
an area 2.7 times greater than the net
cultivation area (UNODC et al. 2007, p.
8). Herbicide spraying has introduced
harmful chemicals into great green
macaw habitat and has led to further
destruction of the habitat by forcing
growers to move to new, previously
´
untouched forested areas (Alvarez 2007,
´
pp. 133–143; BLI 2007d, p. 3; Alvarez
´
2005, p. 2042; Cardenas and Becerra
2004, p. 355; Oldham and Massey 2002,
´
pp. 9–12; Alvarez 2002, pp. 1,088–
1,093).
The ecological impacts of coca
production are significant. Farmers clear
forest to plant coca seedlings. Not only
does each hectare of crop production
result in the clearing of roughly 1.6 ha
(4 ac) of forest, this practice also results
in secondary effects such as the
pollution of land and local waterways
with the chemicals used to process coca
leaves, including kerosene, sulfuric
acid, acetone, and carbide (Butler 2006,
pp. 1–2).
Costa Rica
Most of the research on this species
has been conducted in Costa Rica,
where a very small population of this
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
species remains. Despite Costa Rica’s
progress in conservation of this species,
the historical breeding area for this
species in Costa Rica has been reduced
by 90 percent (Villate et al. 2008, p. 19;
Chosset et al. 2004, p. 38). In 2004,
approximately 30 reproductive pairs
remained in the wild in Costa Rica
(Madriz-Vargas 2004, p. 4). Up until the
1960s, Costa Rica’s human population
was growing by approximately 4 percent
annually (World Bank 2011,
unpaginated; Chun 2008, p. 6). Logging
in the 1960s and 1970s decimated this
species’ habitat (Hardman 2011, p. 8). In
the 1980s, the area near Puerto Viejo de
Sarapiqui experienced severe
deforestation and conversion to banana
and pineapple plantations. By 1996,
52,000 ha (128,495 ac) of lowland forest
had been converted to banana
plantations (Brewster 2009, p. 8). The
loss of forested area in the north has
primarily been due to the production of
livestock, forestry products, sugar cane,
and (in more recent years) pineapple
(Villate et al. 2008, p. 15).
In the mid-1980s, policies changed
from granting incentives for livestock
and cattle ranching to reforestation for
forest management. However, these
incentives led initially to the clearing of
forests for conversion to exotic species
plantations. As a result, forestry in Costa
Rica (and Panama) has been dominated
by the use of exotic species such as
Tectona grandis (teak) or Gmelina
arborea (melina) (Schmidt 2009, p. 10).
This trend changed in 1986 with the
Forestry Act 7472. In the 1990s, the
government began to create incentives
for small farm owners to establish and
maintain native tree species plantations
(Piotto et al. 2003, p. 427). By 1992, a
project was implemented to improve the
use of forested areas; however, it
estimated that by this time only 5
percent of original forest area remained
intact (Chassot et al. 2001 in Villate et
al. 2008, p. 15). Reforestation projects
began initially through an agreement
between Costa Rica and Germany. The
program was implemented by the
Agribusiness Association and Forestry
Producers (APAIFO) and the
Cooperation for Forestry Development
San Carlos (CODEFORSA).
In Costa Rica’s border zone with
Nicaragua, Landsat TM satellite images
from 1987, 1998, and 2005 showed a
fragmented landscape with remnants of
natural ecosystems, which has
implications for the conservation of this
species. The images identified several
classes of cover and land use (natural
forest, secondary forest, water,
agriculture and pasture, banana and
pineapple plantations, and bare ground)
(Chassot et al. 2009, pp. 8–9). These
PO 00000
Frm 00032

researchers noted that the annual rate of
deforestation was 0.88 percent for the
1987–1998 period, and 0.73 percent for
the 1998–2005 period, taking into
consideration recovery of secondary
forest. The researchers also noted that,
in the area studied, deforestation rates
were higher than national averages for
the same time span (Chassot et al. 2009,
p. 9).
In the 1990s, plans to form the San
Juan-La Selva Biological Corridor began
in response to the significant decrease
in habitat available to the great green
macaw and its decline in population
numbers. In 1993 and 1994, about 1,000
km2 (386 mi2) were identified as
important nesting areas for this species
in Costa Rica. In 2002, the San Juan-La
Selva Biological Corridor, an area of
60,000 hectares (148,263 ac), was
established to protect the nesting sites
and migration flyway of the great green
macaw in Costa Rica, up to the
Nicaragua border (Guedes 2004, p. 280).
Although this corridor is in place,
recent reports indicate that habitat
degradation and other factors continue
to affect the great green macaw (Monge
et al. 2009, p. 121).
Costa Rica was the only country in
Central America that had a positive
overall increase in forest area during the
period 2000–2005 (FAO 2010, p. 19;
FAO 2007). Intense efforts are under
way in Costa Rica to conserve and
recover this species, in part by
addressing habitat degradation. In some
areas, the commercial use of the
almendro tree is now being replaced by
synthetic material due to conservation
efforts focused on the great green
macaw. In some areas, landowners are
being paid to protect and ‘‘adopt’’
almendro trees, and several ecotourism
projects have developed using these
trees and the macaws as part of the
ecotourism attraction. As of 2009, 12
nesting trees had protection agreements
(Brewster 2009, p. 10). Still, habitat
degradation continues to impact the
great green macaw (Villate et al. 2008,
p. 14), and even trees that are
designated as protected are either cut
down or targeted for poaching (Chun
2008). Logging still occurs in the
remnant forests of both the northern
zone of Costa Rica and southeast
Nicaragua (Chassot and Arias 2011, p. 1;
Monge et al. 2009, pp. 128–129).
Logging, while it may be illegal, has also
been documented in the buffer zone of
´
the Indio-Maız Biological Reserve
(Monge et al. 2006, p. 10). The buffer
zone is within the breeding range of the
great green macaw and likely affects the
species’ viability. Additionally, both
primary and regrowth forest in the San
Juan–La Selva Biological Corridor

continue to be threatened by timber
extraction and agricultural expansion
(Chassot and Arias 2011, p. 1; Monge et
al. 2009, pp. 128–129).
Mining
Gold mining may also affect
conservation efforts for the great green
macaw in Costa Rica. In 2001, the
Ministerio del Medio Ambiente y
´
Energıa (MINAE) granted a mining
concession (Resolution R–578–2001–
MINAE) in San Carlos to clear nearly
202 ha (500 ac) of old-growth rainforest
for a project (Villate 2009, p. 57; https://
www.infinito.co.cr and https://
www.nacla.org, both accessed
November 15, 2011). The Crucitas
mining project is located in the
Northwest Corridor of San Juan–La
Selva, a few miles from the San Juan
River (which separates Costa Rica from
Nicaragua). The Crucitas area is part of
a major zone for bird conservation
initiatives, partly implemented by BLI,
that includes both the Water and Peace
Biosphere Reserve and the San Juan–La
Selva Biological Corridor (Chassot et al.
2009, p. 9), including the El Castillo
extension. It is reported that 72 percent
of the area that had been proposed for
implementation of the project is forested
and contains almendro tree (and
consequently great green macaw)
habitat. The company proposed to
clearcut the area in order to establish
the open pit mine.
In adjacent Nicaragua, the area of
influence of the mining project is also
part of the buffer zone of the two
reserves: San Juan River Biosphere
´
Reserve and the Indio-Maız Biological
Reserve. These areas contain features of
endemism and species compositions
that are unique (Sistema Nacional de
´
´
Areas de Conservacion (SINAC) 2007 in
Villate et al. 2008, p. 58). Although
Crucitas is not part of the current
nesting area of the great green macaw,
it is only about 10 km (3 mi) southeast
of the historical distribution of the
species. The mining activities are likely
to affect the current population of the
great green macaw by impacting its
habitat as well as ongoing conservation
efforts. The project lies within a
geographical area that is of critical
importance to the conservation of this
species. Additionally, the removal of
more primary forest cover would further
reduce the ability to maintain
connectivity along the San Juan–La
Selva Biological Corridor, which
continues to be subjected to
fragmentation (Villate 2008, p. 58). As of
November 2010, a court ruled that the
open-pit gold mine was improperly
permitted (https://
centralamericadata.biz/en/article/

home/Crucitas_Mining_Concession_
Cancellation_Confirmed, accessed
January 12, 2012). However, prior to the
court ruling, 121 ha (300 ac) of primary
forest had already been cleared (https://
www.santuariolapas.com/profile_
003.html, accessed December 14, 2011).
The ultimate impacts and outcome of
the mining project are unclear; however,
the species is and will continue to be
impacted by pressures for resources that
affect its habitat.
Ecuador
Although the population of great
green macaw is reported to be stable and
slowly increasing in the Cerro Blanco
Protected Forest, it is an extremely
small population (Monge et al. 2009, p.
256). There are likely fewer than 100
individuals remaining in Ecuador. In
this part of its range, three tree species
are noted as crucial for the survival of
the species: Lecythis ampla (salero) and
Cynometra bauhiniaefolia (cocobolo) as
primary food sources, and Cavanillesia
platanifolia (pigio) as a nest tree
(Horstman 2011 pers. comm. 2011).
Logging, poaching, and illegal land
settlements continue to occur in the
great green macaw’s range and are
threats to the population in Ecuador,
particularly in the Cerro Blanco
Protected Forest (https://
www.worldlandtrust-us.org,
unpaginated; World Wildlife Fund
2011, p. 5; Horstman 2011, p. 12).
Between 1960 and 1980, the human
population in Ecuador grew from 4 to
10.2 million, which resulted in more
than 90 percent of Pacific lowland and
foothill forest below 900 m (2,953 ft)
being converted to agriculture (Dodson
and Gentry 1991, p. 279). Much of the
species’ habitat was converted to
plantations of bananas, oil palms, cacao,
coffee, soybeans, and rice (ELAW 2005,
p. 1; Dodson and Gentry 1991, p. 279).
In 2002, the Government of Ecuador
authorized the conversion of 50,000 ha
(123,553 ac) of tropical forest in the
Choco region of western Ecuador into
oil palm plantations (ELAW 2005, pp.
1–2). As of 2005, 374 ha (924 ac) of
native forests were being cut daily
(Horstman 2005, p. 8). Clearing forests
for this monoculture crop has
threatened thousands of endemic
species and introduced dangerous
´
pesticides to local ecosystems (Alban
´
and Cardenas 2007, p. 43). For example,
in Esmeraldas Province, pesticides are
used intensively in a 36,000-ha (88,958ac) area of oil palm plantations (ELAW
2005, pp. 1–2). Local villages cite
problems from the pesticides and
effluents from the processing plants.
The Food and Agriculture
Organization of the United Nations

(FAO) reported in 2010 that, in Ecuador,
‘‘planted forests are predominantly
composed of introduced species,’’ such
as rubber plantations and other
nonnative species (FAO 2010, p. 93),
which do not provide appropriate
habitat and nutritional needs for the
great green macaw. Despite these
activities, due to the efforts of the
ProForest Foundation—the NGO in
charge of the reserve—the population in
the Cerro Blanco forest preserve is
reported to be stable (Horstman 2011, p.
17). The Cerro Blanco forest preserve is
a small area that is being managed
particularly for this species. It is jointly
owned by the ProForest Foundation and
a cement company, Holcim, as
mitigation for its nearby limestone
quarries. Reserve managers are
converting former cattle pasture to
native tree farms, which they use to
help restore dry tropical forest in other
locations, including a corridor to nearby
patches of forested areas (Horstman
2009 pers. comm.). Despite the
conservation efforts in place, logging,
poaching, and illegal land settlement
continue to affect the population in the
Cerro Blanco Protected Forest
(Horstman 2011, p. 17; Fundacion ProBosque, undated, p. 3). A conservation
strategy for this species recommends
that a ban be instituted on the cutting
and commercialization of the three tree
species described above that were noted
as crucial for the great green macaw’s
survival (Monge et al. 2009, pp. 256–
258). However, deforestation,
encroachment, and habitat degradation
activities such as these continue
(Horstman 2011, p. 17).
Another threat to the macaw’s
population in this reserve is the rapid
expansion of the city of Guayaquil.
Squatter settlements develop on the
city’s outskirts and encroach the forest
(Fundacion ProBosque undated, p. 3).
Illegal settlements are a problem, and
squatter communities have attempted to
take over property within Cerro Blanco.
The local NGO conducts educational
awareness programs to mitigate these
activities. An example of awareness
campaign activities is educating the
local communities about the effect on
their water supply when they destroy
forested areas (Horstman pers. comm. in
Hardman 2011, p. 13). However,
pressures to this species’ habitat
continue to impact the species.
Honduras
In Honduras, threats have included
illegal trafficking of this species and
deforestation due to agriculture, cattle
grazing, and logging (Devenish et al.
2009, p. 256). The threat of deforestation
is particularly important because a

recent study found that 87 percent of
Honduras is only suitable for forest
(Larios and Coronado 2006, p. 13) due
to its generally mountainous terrain.
There is very little information available
on the status of this species in
Honduras, particularly scientific
literature (Monge et al. 2009, p. 122).
Only six papers on avian diversity and
avian population surveys in Honduran
forests were published between 1968
and 2004 (Anderson et al. 2004, p. 456).
However, we do know that the threats
in Honduras are similar to those in other
countries within the range of this
species (McCann et al. 2003, pp. 321–
322), and the most significant threat is
deforestation. In 2008, the
´
Departamento de Areas Protegidas y de
Vida Silvestre (DAPVS) in Honduras
estimated that 80,000 ha (197,684 ac) of
natural areas were being destroyed
annually (DAPVS 2008 in Devenish et
al., 2009 p. 256).
The great green macaw is believed to
´
´
exist in the Rıo Platano Biosphere
Reserve within the watershed of the
´
Platano River (Monge et al. 2009, p. 8).
The area is also known as the
˜
‘‘Mosquitia Hondurena,’’ which is
500,000 ha (1,235,527 ac) in size. The
reserve serves as protection to the 100´
km (62-mi) long Platano River
watershed in addition to protecting
parts of the Paulaya, Guampu, and Sicre
rivers (Devenish 2009, p. 256). Several
indigenous tribes such as the Miskito,
´
Tawahka, Pech, Garıfunas, and
‘‘Mestizos’’ use this area for their
traditional livelihoods. Although this
reserve was designated as a World
Heritage Site, pressures to the reserve
area for its resources continue (TNC
´
2011, unpaginated). In 2011, the Rıo
´
Platano Biosphere Reserve was added to
the list of World Heritage Sites in
danger due to encroachment (UNEP–
WCMC 2011, p. 1).
´
´
In the Rıo Platano Biosphere Reserve
of Honduras, the unregulated extraction
of timber and mass production of
bananas has caused an alarming decline
of great green macaw populations
(Devenish et al. 2009, p. 256). The
deforestation in Honduras is occurring
as a result of an increase in the human
population, which requires clearing
areas for home development as well as
wood products (Devenish et al. 2009, p.
256). The annual human population
growth rate as of 2011 was estimated to
be 1.09 percent (U.S. Department of
State 2011, unpaginated). Palacios and
Brus Laguna, towns on the coast
approximately 5 km (3.1 mi) from the
park on either side of the reserve, are
likely contributing to the pressures such
as agriculture and logging that are
occurring illegally in the reserve.

Nicaragua
In Nicaragua, great green macaws face
reductions in populations due to illegal
extraction of timber and agricultural
expansion (McGinley et al. 2009, pp. 13,
33, 35; Jeffrey 2001, pp. 1–5). Overall,
there is a lack of information about the
status of the great green macaw
population and its habitat in Nicaragua
(Monge et al. 2010; Monge et al. 2009,
pp. 52–53). However, a population of
the great green macaw is known to
´
occur in the Indio-Maız Biological
Reserve, located in Nicaragua just across
the San Juan River at the northeastern
border of Costa Rica (Monge et al. 2009,
p. 51), where suitable habitat for this
species remains. This reserve, which is
believed to be one of the few
strongholds for the great green macaw,
is nearly 264,000 ha (652,358 ac) in size.
´
It is likely that the Indio-Maız Biological
Reserve contains extensive forest areas
with high densities of almendro trees
(Chun 2008, p. 94) and, therefore, is
critical to this species’ survival. Chun
suggests that many areas in Nicaragua
may exceed the minimum great green
macaw nesting requirement of 0.20 trees
per hectare within the breeding
´
territory. Although the Indio-Maız
Biological Reserve is considered one of
Nicaragua’s best preserved forested
areas and has limited access, its buffer
zone has recently been under assault
from activities such as loggers in search
of lumber and illegal farming of Elaeis
guineensis (African palm) trees for
biofuel (Chosset and Arias 2010, p. 3;
Ravnborg et al. 2006, p. 2). As resources
become scarcer in the buffer zones,
illegal activities push farther into the
lesser disturbed and lesser accessible
areas. Despite the existence of this
protected area, deforestation continues
to occur.
Deforestation is one of the major
threats to biodiversity in this region; one
steadily increasing form is the
conversion of forest into agricultural or
pastural lands (Chassot et al. 2006, p.
84). In Nicaragua, between 1990 and
2005, 1.35 million ha (3.34 million ac)
of forested areas were converted to
agriculture or were deforested due to
other reasons such as logging (FAO
2010, p. 232; FAO 2007). Much of
Nicaragua has protected status. In 2005,
approximately 36 percent of Nicaragua’s
forested area was designated as
protected or in some form of
conservation status (FAO 2007).
Additionally, in 2007, there were 72
protected areas in Nicaragua’s National
System of Protected Areas (Castellon
2008, p. 19). However, 88 percent of
Nicaragua’s area designated as forest is
privately owned (FAO 2010, p. 238)
PO 00000
Frm 00034

and, therefore, is not protected.
Additionally, much of the logging that
occurs is illegal and is not monitored
(Pellegrini 2011, p. 21; Richards et al.
2003, p. 283).
As an example, the Bosawas Reserve
is one of the areas believed to contain
great green macaws as well as suitable
habitat for a viable population. It was
designated a reserve in 1979, in
response to the advance of the
´
agricultural frontier (Cuellar and Kandel
2005, p. 9). However, during the 1980s,
the area was not managed; it was the
battleground for the armed conflict
between the Sandinistas and the Contras
´
(Cuellar and Susan Kandel 2005, p. 9).
In October 1991, Bosawas was declared
a National Natural Resource Reserve
through Executive Decree No. 44–91.
Despite its designation as a protected
area, encroachment and habitat
degradation still occur (McCann et al.
2003, p. 322). In Bosawas, indigenous
tribal communities have rights to use
the forests under the Autonomy Statute
´
of 1987 (Cuellar and Kandel 2005, p.
11). As of 1998, the indigenous
population was approximately 9,200 in
or near the Bosawas reserve (Stocks et
al. 2007, p. 1,497). In 2005, the
Nicaraguan Government granted land
titles to 86 indigenous Miskitu and
Mayangna groups in Bosawas and
contiguous indigenous areas (Stocks et
al. 2007, p. 497). Generally, these
indigenous communities manage the
forests well and want to maintain their
traditional way of life. However,
‘‘mestizo’’ communities were
encouraged to settle in the area that is
now the reserve’s buffer zone during the
period when lands were being
converted to plantations. Both the
mestizo and indigenous communities
depend on access to land to ensure their
livelihoods. However, the mestizo
communities convert primary forest to
´
agricultural or livestock uses (Cuellar
and Kandel 2005, p. 13), while the
indigenous communities have less
impact on the ecosystem. Land rights
disputes are common in these areas, and
land use rights are often unclear. The
Government of Nicaragua is attempting
to manage these issues (Pellegrini 2011,
p. 21), but conflict and practices that
degrade the great green macaw’s habitat
persist both in the Bosawas Reserve and
in other areas within the range of the
species.
One of the factors contributing to
deforestation in this area is a high rate
of poverty (Pacheco et al. 2011, p. 4).
Nicaragua is the poorest country in
Central America (CIA World Factbook
2014). In part, due to the high rate of
poverty, the great green macaw
continues to face threats to its habitat.

Communities living within the range of
the great green macaw practice
unsustainable activities, such as
conversion of habitat to agriculture or
logging, which contribute to
deforestation of the species’ remaining
habitat in Nicaragua (McGinley 2009, p.
36; Castellon 2008, pp. 21, 30; Richards
et al. 2003, p. 282). Much of the Indio´
Maız Biological Reserve is described as
being intact and unlogged (Chun 2008,
p. 116). Despite this, some loggers cross
the border into Nicaragua to harvest the
almendro tree (Schmidt 2009, p. 16;
Chassot et al. 2006, p. 84). Anecdotal
reports indicate that Costa Rican loggers
pay Nicaraguan farmers about $15 for
each almendro tree, bring the logs to
Costa Rica, and sell them for about
$1,450 in Costa Rica (Arias 2002, p. 4).
Because incomes in the Bosawas region
of Nicaragua were found to average
under $800 per family per year (Stocks
et al. 2007, p. 1,498), the almendro trees
are quite valuable. Consequently, a
binational biological corridor between
Nicaragua and Costa Rica was proposed
in an attempt to prevent the extinction
of the almendro tree (Chassot et al.
2006, p. 84). Although this corridor
exists and efforts are in place (refer to
discussion under Factor D, below) to
mitigate border issues (Hernandez et al.,
undated, pp. 1–14) in this region,
habitat degradation continues.
Panama
In Panama, this species is believed to
´
primarily exist in the Darien region,
which borders northern Colombia
(Angeher 2004, in litt.). Deforestation
was estimated to exceed 30 percent of
the species’ original range in Panama
(Angehr 2004, in litt.). Although there is
limited information available on the
threats affecting great green macaw
populations in Panama, deforestation is
known to occur within this species’
range (Monge et al. 2009, p. 68; Angehr
2004, in litt.). Conflict regarding land
rights of indigenous communities has
become one of the most critical issues
´
in the Darien region. The most
significant threats to tropical forests in
Panama overall include road
construction and road improvement,
´
especially in the Darien region, and
agricultural expansion, particularly in
´
the Darien and Bocas del Toro regions,
which results in increased access to
forests (Parker et al. 2004, p. V–2).
Roads have been found to be one of the
leading causes of global biodiversity
´
´
loss (Benıtez-Lopez et al. 2010, p.
1,307). The construction of the PanAmerican Highway and other roads are
´
affecting the Darien forest area (TNC
2011, p. 1). When roads are constructed,
they increase access to previously
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
inaccessible areas. This leads to more
pressures on the forested areas, such as
conversion to agriculture, competition
for resources (such as the extraction of
plant species that may be consumed by
the great green macaw), and more
logging.
A 2006 report indicated that the
advance of the agricultural frontier and
‘‘spontaneous colonization’’ occurring at
a rate of 50,000 to 80,000 ha (123,500 to
197,700 ac) per year is rapidly shrinking
Panama’s forests and protected areas
(McMahon et al. 2006, p. 8). Prior to its
formal designation in 1990, La Amistad
National Park, which spans the border
between Costa Rica and Panama,
experienced impacts from cattle
ranching, timber extraction, burning,
and illegal settlements (UNEP–WCMC
2011, p. 7). Trails, human
encroachment, roads, grazing, and
hunting continue in this area and affect
this species’ habitat (TNC 2012,
unpaginated; UNEP–WCMC 2011, p. 7).
Soil and water resources have been
depleted due to traditional agricultural
practices and inadequate conservation
measures. Indigenous production
systems, with their low-intensity land
use, long rotation periods, and plentiful
forests for hunting and gathering, are
increasingly becoming unsustainable
due to economic pressures. These
indigenous production systems are
being replaced by farming systems that
emphasize monoculture without
rotation, which leads to depleted soils
and encourages greater expansion of the
agricultural frontier. These threats are
exacerbated by rural poverty that drives
populations in search of areas with high
levels of globally significant biodiversity
(Pacheco et al. 2011, pp. 4, 18). As a
result of competition for resources,
many farmers and indigenous people
´
have emigrated to the Darien and Bocas
del Toro provinces, where the great
green macaw is believed to exist in
larger numbers than in other parts of the
species’ range. Unsustainable land
practices, the lack of capacity by both
public and private stakeholders to
encourage sustainable land use,
infrastructure development, and the
lack of management plans further
exacerbate the degradation of this
species’ habitat.
´
Darien forests are under pressure from
the expanding agricultural frontier and
related colonization (TNC 2011, p. 1;
McMahon 2006, p. 8). The region’s
human population is growing at a rate
of about 5 percent a year. Loss of forest
cover is often linked to agricultural
expansion, which often follows new or
improved roads, and which results in
increased access to forests. Slash-andburn agriculture has resulted in huge
PO 00000
Frm 00035
Fmt 4701
Sfmt 4700
60009
tracts of deforested land. Other factors
that affect the stability of great green
macaw populations include the
National Authority for the
Environment’s (ANAM) inability to
fund programs for protected areas and
buffer zones, and the extraction of other
minerals and building materials,
whether legal or illegal (Angehr et al.
2009, p. 291). Logging and mining is
legally restricted in the area; however,
´
logging still occurs outside the Darien
reserve, and the practice encroaches on
remaining forest cover in the buffer
zone. Problems in or adjacent to
protected areas include illegal clearing
for development, agriculture, and cattle
grazing; road construction; and
extraction of minerals or construction
materials (Devenish et al. 2009b, p. 291).
The presence of gold mines in the
´
Darien Region, particularly the Cerro
Pirre area, was also indicated to be a
threat to the species. Significant mining
activities in this area were conducted
prior to the 18th century. The clearing
of forests to create roads for mining
facilitates the transport of materials and
personnel in and out of the mining
zones (Robbins et al. 1985, pp. 200,
202). Roads exacerbate deforestation
practices such as logging and
conversion to agriculture or other land
uses, as well as colonization. This area
is now an ecotourism site; as of 1985,
there is now second-growth forest
recovery from the gold mines that had
been abandoned during the 18th
century. It does not appear that mining
in this area still occurs, and, therefore,
mining is not currently impacting the
species.
Summary of Factor A
The global population of great green
macaws is decreasing due to the loss of
much of the older forested areas, thus
reducing high-quality habitat for this
species, and relegating it to relatively
small and isolated patches throughout
its range; however, suitable habitat
remains in some protected areas in
Central and South America. Habitat
degradation poses a significant threat
throughout the range of the great green
macaw, which is especially vulnerable
to the effects of isolation and
fragmentation because it tends to mate
for life, it has a small clutch size and
specialized habitat requirements, and its
populations are small and decreasing.
The great green macaw is naturally
associated with unfragmented, mature,
forested landscapes, and is considered a
habitat specialist that selects areas of
contiguous mature forest in Central
America and parts of northern South
America (Monge et al. 2009; MadrizVargas 2004, p. 7). This species requires

asabaliauskas on DSK5VPTVN1PROD with RULES
large areas for its feeding requirements
and is not well adapted to fragmented
landscapes. Deforestation results in
fragmented forests with high ratios of
edge to forested area, and the original
biodiversity upon which this species
depends is lost. Greater exposure of soil
to direct sunlight leads to factors such
as drier soils and also creates an altered
growing environment. Because there are
fewer remaining older, complex forest
stands providing adequate habitat for
breeding, feeding, and nesting, great
green macaw populations are in decline.
The great green macaw is threatened by
the impacts of both past and current
habitat loss, including ongoing habitat
modification that results in poor quality
and insufficient forest habitats, habitat
fragmentation, and isolation of small
populations. The ability of the great
green macaw to repopulate an isolated
patch of suitable habitat following
decline or extirpation is particularly
unlikely due to the species’ large home
range requirements, and this is
exacerbated by its small overall
population size and the large distances
between the remaining primary forest
fragments. Despite the existence of the
binational corridor in Nicaragua and
Costa Rica and a multitude of
conservation efforts, we find that the
present or threatened destruction,
modification, or curtailment of habitat is
a threat to the great green macaw now
and in the future.
B. Overutilization for Commercial,
Recreational, Scientific, or Educational
Purposes
Because this species has an extremely
small and fragmented population,
poaching, while apparently uncommon,
remains a concern (Botero-Delgadillo
´
and Paez 2011, p. 13; Monge et al. 2009,
pp. 26, 40, 106). Removal of this species
from the wild has a significant
detrimental effect to this species
because this species tends to mate for
life and only produces 1 or 2 eggs
annually. The species has been heavily
poached in the wild historically and is
still trafficked for the pet trade in
Honduras and Nicaragua (Anderson
2004, p. 453; https://
www.lafeberconservationwildlife.com/
?p=1714, accessed December 14, 2011).
Although there are no known current
reports of poaching in all parts of its
range, poaching was raised as a concern
at the 2008 workshop held in Costa Rica
on this species (Monge et al. 2009,
various). After regulatory mechanisms
such as CITES and the WBCA were put
into place, particularly since 1992 when
the WBCA went into effect, much of the
legal trade in the great green macaw
declined (see discussion of military

macaw for more information about
WBCA) (UNEP–WCMC CITES trade
database, accessed September 6, 2011).
The great green macaw was listed in
CITES Appendix II, effective June 6,
1981, and was transferred to Appendix
I, effective August 1, 1985. Most of the
international trade in great green macaw
specimens consists of live birds.
Data obtained from the United
Nations Environment Programme–
World Conservation Monitoring Center
(UNEP–WCMC) CITES Trade Database
show that, during the 4 years the great
green macaw was listed in Appendix II,
26 live great green macaws (and an
additional eight feathers) were reported
to UNEP–WCMC as (gross) exports. In
analyzing the data, it appears that
several records may be overcounts due
to slight differences in the manner in
which the importing and exporting
countries reported their trade. It is likely
that the actual number of live great
green macaws in international trade
during this period was 22. All of the live
birds were reported with the source
‘‘unknown.’’ Exports from range
countries included six live birds from
Panama and five live birds from
Nicaragua (UNEP–WCMC 2011).
During the more than 28 years
following the transfer of the species to
Appendix I (August 1985 through
December 2013, the last year for which
complete data were available at the time
the following numbers were compiled),
the UNEP–WCMC database shows 920
live birds in international trade.
However, because it is some over-counts
likely occurred in the database due to
slight differences in the manner in
which the importing and exporting
countries reported their trade, it is likely
that the actual number of live great
green macaws in international trade
during this period was 831 (U.S. CITES
Management Authority 2015). Of these,
776 were reported to be captive-bred or
captive-born, 5 were reported as wild,
and 15 were reported as ‘‘preConvention.’’ The source of the
remaining live birds is unknown.
Exports of live birds from range
countries included 17 from Costa Rica,
10 from Ecuador, 12 from Nicaragua,
and 6 from Panama. Note also that some
of these birds may be personal pets that
are counted more than once.
Historically, the pressure to remove
this species from the wild for the pet
trade has contributed significantly to the
decline in population numbers for this
species. Poaching continues to occur in
this species’ range, particularly in
Nicaragua (Castellon 2008, pp. 20, 25;
Kennedy 2007, pp. 1–2; BLI 2007, p. 1).
The majority of information available
for Central America regarding poaching

Frm 00036

and the sale of parrot species were
focused in Nicaragua (Herrera-Scott
2004, pp. 1–2). A study published in
2004 assessed the origin and local sale
and export of parrots and parakeets in
Nicaragua (Herrera-Scott 2004, pp. 1–2),
and focused on the buffer zone of the
´
Indio-Maız Biological Reserve, a critical
area for the great green macaw. The
study followed the marketing chain
from rural areas to the capital city. Most
of the wildlife trade was found to occur
in Managua. As of 2000, poaching was
still occurring in the buffer zone of the
´
Indio-Maız Biological Reserve (HerreraScott 2004, p. 6). An estimated 7,205
parrots were sold during that year
(Herrera-Scott 2004, p. 1). The legal
export of wildlife species from
Nicaragua in general decreased
significantly between 2002 and 2006
(McGinley 2009, p. 16). Despite the
decrease in legal trade, in 2007, a
number of parrot species could be still
found for sale along roads to tourists
(Kennedy 2007, pp. 1–2; BLI 2007, p. 1).
Nicaragua is the poorest country in
Central America and the second poorest
in the Hemisphere, and has widespread
underemployment and poverty (CIA
World Factbook 2011, unpaginated;
FAO 2011, p. 1). Approximately 17
percent of its population lives in
extreme poverty (Castellon 2008, p. 21).
Many of Nicaragua’s citizens live in
rural areas where they usually earn a
living from agriculture and fishing, and
the sale of a parrot can significantly
increase their earnings. As mentioned
above under the Factor A discussion,
incomes in the Bosawas region of
Nicaragua were found to average under
$800 per family per year as of 2007
(Stocks et al. 2007, p. 1,498). The great
green macaw was found for sale at an
average of $200 to $400 U.S. dollars
(USD) (Fundacion Cocibolca in BLI
2007, p. 1). For perspective, in the
United States, captive-bred specimens
can sell for up to $2,500 USD (Basile
2009, p. 6). The high commercial value,
especially in relation to the average
family income, indicates that it is still
worthwhile to poach and sell this
species. Due to the extreme poverty in
Central America, particularly in
Nicaragua, and due to the high
commercial value of great green
macaws, poaching continues to be a
significant concern for this species.
Poaching can be intertwined with
habitat destruction (Factor A). Some
poachers still cut down trees to obtain
nestlings (Hardman 2011, p. 13; Chun
2008, p. 105). This practice of cutting
down trees to remove nestlings is
particularly devastating to small
populations reliant upon certain types
E:\FR\FM\02OCR3.SGM
02OCR3
60011
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
and sizes of nesting trees. Not only are
poachers removing vital members of the
population, they are destroying a nest
site that may have taken a breeding pair
several years to find and cultivate. One
study looked at 51 nest sites that had
been identified between 1994 and 2003
(Chun 2008, p. 105). The study
evaluated potential habitat by
examining the presence and density of
almendro trees by aerial survey. It
examined portions of two protected
areas—the San Juan-La Selva Biological
Corridor and the Maquenque National
Wildlife Refuge (Chun 2008, p. 117). Of
51 nest sites, 10 trees had been cut by
the end of the survey period. In some
cases, the nests had been deliberately
cut even after the tree had received
protection status and had been
distinguished as a nesting tree with a
plaque. Nest destruction has also been
reported in Ecuador (Bergman 2009, pp.
6–8), where it is estimated to have an
extremely small population. Another
study confirmed the presence of nest
destruction, although this was a
different parrot species, and found an
average of 21 nests was destroyed per
poaching trip (Gonzalez 2003, p. 443).
Poaching for the pet bird trade can
destroy pair bonds, remove potentially
reproductive adults from the breeding
pool, and have a significant effect on
small populations (Kramer and Drake
2010, pp. 511, 513). This is in part
because this species mates for life, is
long-lived, and has low reproductive
rates. These traits make them
particularly sensitive to the effects of
poaching (Lee 2010, p. 3; Thiollay 2005,
p. 1121; Wright et al. 2001, p. 711). In
some areas in Costa Rica, there were no
recent reports of nest poaching due to
conservation efforts (Villate et al. 2008,
p. 23). However, despite conservation
efforts in place, the conservation
workshop for Ara ambiguus held in
2008 indicated that poaching of this
species is still a concern throughout its
range (Monge et al. 2009, pp. 18, 26, 29,
40).
Summary of Factor B
Conservation efforts by various
entities working to ensure the long-term
conservation of the great green macaw
may result in its population slowly
increasing (Monge et al. 2010, pp. 12–
13). However, overall, the best available
information indicates that the
population is still declining (Botero´
Delgadillo and Paez 2011, p. 91; Monge
et al. 2009). The species still faces
threats such as habitat loss and
poaching. Often, there is a lag time after
factors have acted on a species (i.e.,
poaching and habitat loss) before the
effect is evident (Sodhi et al. 2004, p.
325). Even though the great green
macaw is listed as an Appendix-I
species under CITES and commercial
international trade is now significantly
reduced, there is still concern about the
illegal capture of this species in the
wild. This species is desirable as a pet,
and its native habitat is in impoverished
countries, where the sale of an
individual bird can significantly
increase an individual’s income. Despite
regulatory mechanisms in place,
poaching is lucrative and still occurs.
Additionally, because each population
of great green macaws is small, with
possibly between 10 to 500 individuals
(Monge et al. 2010, pp. 21, 22), poaching
is likely to have a significant effect on
the species. The populations are
distributed widely throughout the range
of the species (see Figure 3) and are
highly fragmented, and the amount of
interaction between populations is
unknown but likely infrequent. Based
on the best available information, we
find that overutilization, particularly
due to poaching, is a threat to the great
green macaw throughout its range now
and in the future.
C. Disease or Predation
We have no evidence of significant
adverse impacts to wild populations of
great green macaws due to disease.
Diseases are a normal occurrence within
wild populations. They do not occur to
an extent that they are a threat to this
species, particularly because the
populations are widely dispersed,
which provides an element of resiliency
to the overall population. We conclude,
based on the best available scientific
and commercial information, that
disease is not a threat to the great green
macaw now or in the future.
In addition, we have no information
indicating that predation threatens the
great green macaw. This is the second
largest New World macaw, and the best
available information does not indicate
that predation is a factor that negatively
affects this species. While predators
undoubtedly have some effect on
fluctuations in great green macaw
numbers, there is no evidence to suggest
that predation has caused or will cause
long-term declines in the great green
macaw population. Therefore, we have
determined that this factor does not
pose a threat to the great green macaw,
now or in the future.
D. The Inadequacy of Existing
Regulatory Mechanisms
Regulatory mechanisms affecting this
species that we evaluated could
potentially fall under categories such as
wildlife management, parks
management, or forestry management.
We primarily evaluated these regulatory
mechanisms in terms of nationally
protected parks because this is where
this species generally occurs. A
summary of the status of forest policies,
regulatory mechanisms, and laws in the
range countries of the great green
macaw is below. The most authoritative
source for assessing the state of forests
is the United Nations Food and
Agriculture Organization’s Forest
Resources Assessment (FAO) (Chomitz
et al. 2007, p. 42). FAO’s 2010 study
found that each range country for this
species has a national forest law, policy,
or program in place, and Table 1
indicates the year it was last evaluated.
However, the study found that few
forest policies at the subnational level
(such as jurisdictions equivalent to
states in the United States) exist in these
countries.

Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
In 2007, FAO noted that many
countries (in the range of the great green
macaw) had enacted new forest laws or
policies within the past 15 years, or had
taken steps to strengthen their existing
legislation or policies. Among countries
that had enacted new forest legislation
were Costa Rica, Honduras, Nicaragua,
Panama, Colombia, and Ecuador (FAO
2007, p. 43). Despite the existence of
these laws and policies, the populations
of the great green macaw are still
negatively affected by habitat loss,
encroachment, and, to a lesser extent,
poaching.
Parks and Habitat Management
Throughout this species’ range, we
found that many of the threats that
occur to this species are the same or
similar. Threats generally consist of
various forms of habitat loss or
degradation (see Factor A discussion,
above). Each range country for this
species has protections in place, but for
reasons such as limited budgets and
limited enforcement capabilities, the
laws and protections are generally not
able to adequately protect the species.
Our analysis of regulatory mechanisms
is discussed essentially on a country-bycountry basis, beginning with Colombia,
and is summarized at the end.

Colombia
Colombia has enacted numerous laws
to protect species and their habitats.
This species exists predominantly in
areas that are protected, and Colombia
has several laws that pertain to
protected areas. Some of these laws
include:
• Natural Resources and Decree Law
number 2811/74.
• Decree 1974/89: Regulation of Article
310 of Decree 2811, 1974, on
integrated management districts of
natural renewable resources.
• Law number 99/93: Creates the
Ministry of the Environments and the
National Environmental System.
• Law number 165/94: Biological
Diversity Treaty.
• Decree 1791/96: Establishment of the
Forest Use Regime.
A list of legislation that applies to
protected areas in Colombia is available
at https://www.humboldt.org.co/ingles/
en-politica.htm and at https://
www.regulations.gov in Docket No.
FWS–R9–ES–2011–0101. A discussion
of Colombia’s regulatory mechanisms
with respect to the great green macaw
follows.
The great green macaw is listed as
vulnerable on Colombia’s Red List
(Renjifo et al. 2002, p. 524). Resolution
No. 584 of 2002 provides a list of
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
Colombian wildlife and flora that are
considered ‘‘threatened.’’ Colombia
defines threatened as those species
whose natural populations are at risk of
extinction if their habitat, range, or the
ecosystems that support them have been
affected by either natural causes or
human actions. Threatened species are
further categorized as critically
endangered, endangered, or vulnerable.
Colombia defines a critically
endangered species as one that faces a
very high probability of extinction in
the wild in the immediate future, based
on a drastic reduction of its natural
populations and a severe deterioration
of its range. An endangered species is
one that has a high probability of
extinction in the wild in the near future,
based on a declining trend of its natural
populations and a deterioration of its
range. A vulnerable species is one that
is described as not in imminent danger
of extinction in the near future, but it
could be if natural population trends
continue downward and deterioration of
its range continues (EcoLex 2002, p. 10).
Colombian Law No. 99 of 1993
created the Ministry of the Environment
and Renewable Natural Resources and
the National Environmental System
(SINA). SINA sets out the principles
governing environmental policy in
Colombia, and provides that the
country’s biodiversity is protected and
used primarily in a sustainable manner
(Humboldt Biological Resources
Research Institute 2011, unpaginated;
EcoLex 1993, p. 2). SINA is a set of
activities, resources, programs, and
institutions that allow the
implementation of environmental
principles. Consistent with the
Constitution of 1991, this management
system was intended to be
decentralized. However, an
environmental assessment study
conducted for the World Bank in 2006
found that Colombia’s current
decentralized system is inadequate as
implemented (Blackman et al. 2006, p.
15). Although Law 99 assigns the role of
leading and coordinating environmental
management in Colombia to the
Ministry of Environment (Ministerio del
Medio Ambiente, MMA), Colombia’s
Autonomous Regional Corporations
(CARs) have the role of implementing
environmental laws (Blackman et al.
2006, pp. 39–40, 42). CARs have
responsibility for both management of
natural resources and economic
development (Ministry of Environment
et al. 2002).
In 2006, an analysis of the
effectiveness of Colombia’s CARs was
conducted for the World Bank. In
Blackman et al. 2006’s analysis, they
reported that many individuals both
PO 00000
Frm 00038
Fmt 4701
Sfmt 4700
inside and outside the government felt
there was a lack of effectiveness of
SINA. For example, Colombia’s efforts
to eradicate the coca trade has not been
effective at reducing the amount of coca
being cultivated (Page 2003, p. 2; also
see The present or threatened
destruction, modification, or
curtailment of its habitat or range). In
addition to not adequately addressing
the coca cultivation, which destroys the
great green macaw’s habitat, aerial
fumigations of the coca crop have
destroyed banana fields and polluted
the environment (Page 2003, p. 2). The
effectiveness of these regional
management groups varied; the study
found that the effectiveness was
correlated with the CARs’ age,
geographic size, and level of poverty
(Blackman et al. 2006, p. 16). Due to the
decentralized structure, CARs were
found to be ineffective at environmental
management in Colombia (Blackman et
al. 2006, p. 14).
This species’ habitat occurs to some
extent in areas designated as protected
by SINA, including five national parks
´
(Rodrıguez-Mahecha 2002a). Two parks
´
are particularly significant: Katıos
´
National Park and Utrıa National Park.
Although this species likely exists in at
least these two parks (Botero-Delgadillo
´
and Paez 2011, p. 92), no protective
measures have been actually
implemented to curb human impacts on
the species’ habitat by the indigenous
and farming residents within these
protected parks (Botero-Delgadillo and
´
Paez 2011, p. 92). Cultivation of plants
for cocaine production is known to
´
occur within the boundaries of Katıos
National Park. The cultivation of illegal
crops (particularly coca) poses
additional threats to the environment
beyond the destruction of montane
forests (Balslev 1993, p. 3). Coca crop
production destroys the soil quality by
causing the soil to become more acidic,
depletes the soil nutrients, and
ultimately impedes the regrowth of
secondary forests in abandoned fields
(Van Schoik and Schulberg 1993, p. 21;
also see The present or threatened
destruction, modification, or
curtailment of its habitat or range
discussion, above). As of 2007,
Colombia was the leading coca producer
(United Nations Office of Drugs and
Crime (UNODC) et al. 2007, p. 7). Since
2003, cocaine coca cultivation has
remained stable at about 800 km2 (309
mi2) of land under cultivation (UNODC
et al. 2007, p. 8). This activity continues
to degrade and destroy great green
´
macaw’s habitat. With respect to Utrıa
National Park, little to no information is
known about the status of the species in
E:\FR\FM\02OCR3.SGM
02OCR3
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
´
this area (Botero-Delgadillo and Paez
2011, p. 91). Although it is extremely
remote, human communities reside
within and around the park, and
continue to use the resources within the
park.
Despite Colombia’s numerous laws
and regulatory mechanisms to
administer and manage wildlife and
their habitats, the great green macaw
continues to face many threats to its
habitat. There is little information
available about the species (Botero´
Delgadillo and Paez 2011, p. 90), and
the most recent information indicates
that no conservation action has been
proposed for this species (Botero´
Delgadillo and Paez 2011, p. 88). Onthe-ground enforcement of existing
wildlife protection and forestry laws,
and oversight of the local jurisdictions
implementing and regulating activities,
are ineffective at mitigating the primary
threats to the great green macaw. As
discussed under The present or
threatened destruction, modification, or
curtailment of its habitat or range
(above), habitat destruction,
degradation, and fragmentation
continue throughout the existing range
of the great green macaw. Therefore, we
find that the existing regulatory
mechanisms currently in place are
inadequate to mitigate the primary
threats of habitat destruction to the great
green macaw in Columbia.

Costa Rica
In Costa Rica, there are more than 30
laws related to the environment
(Peterson 2010, p. 1). A list of the
environmental laws in Costa Rica is
available at: https://
www.costaricalaw.com/costa-ricaenvironmental-laws.html. As
deforestation is the most significant
factor affecting the great green macaw,
some laws applicable to the
conservation of the great green macaw
are:
• Law No. 2790 Wildlife Conservation
´
Law (‘‘Ley De Conservacion De La
Fauna Silvestre,’’ July 1961).
• Law No. 7317 Wildlife Conservation
´
Law (‘‘Ley De Conservacion De La
Vida Silvestre,’’ December 1992).
• Law 7554 Law of the Environment
´
(‘‘Ley Organica del Ambiente,’’
October 1995).
• Law No. 7575 Forestry Law (‘‘Ley
Forestal,’’ February 1996).
• Law 7788 Biodiversity Law (In 1998,
the National System of Conservation
Areas (SINAC) was created through
this law (Canet-Desanti 2007 in
Villate et al. 2008, p. 24).
In the early 1990s, Costa Rica had one
of the highest deforestation rates in
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
Latin America (Butler 2012, p. 3). Forest
cover in Costa Rica steadily decreased
from 85 percent in 1940, to around 35
percent today, according to the FAO’s
State of the World’s Forests (Butler
2012, unpaginated; FAO 2010, pp. 227,
259; FAO 2007). Historically, clearing
for agriculture, particularly for coffee
and bananas, in addition to cattle
pastures was the main reason for Costa
Rica’s rainforest destruction. During the
1970s and early 1980s, vast expanses of
rainforest had been burned and
converted to cattle pastures. Today,
although deforestation rates of natural
forest have dropped considerably, Costa
Rica’s remaining forests still experience
illegal timber harvesting (in protected
areas) and conversion to agriculture (in
unprotected zones) (Butler 2012,
unpaginated; Monge et al. 2009, p. 121;
FAO 2007). Despite its abundance of
conservation legislation, Costa Rica has
undergone significant periods of
deforestation (Butler 2012, unpaginated;
FAO 2007, p. 38), which have had a
severe effect on the great green macaw.
Almendro Tree Protection
In Costa Rica and Nicaragua, the great
green macaw is highly dependent on the
almendro tree. This tree species is now
protected by law in Costa Rica; cutting
any almendro tree over 120 cm (47.2 in)
or less than 70 cm (27.6 in) in diameter
is prohibited (Rainforest Biodiversity
Group 2008, p. 1). The remaining Costa
Rican populations of almendro trees are
concentrated in the northeastern corner
of the country from the San Juan River
south to Braulio Carrillo National Park
(Hanson 2006, p. 3). Although little
forest remains undisturbed in this
region, many almendro trees were left
standing in fragments or pastures, partly
due to the extremely dense nature of the
tree’s wood and the difficulty in cutting
down these trees.
As a result of the great green macaw’s
dependence on almendro trees,
conservation efforts for the great green
macaw have focused on this tree
species. A decree was enacted in 2001
to limit extraction of the almendro tree.
Harvest was temporarily suspended
until a study could be conducted to
evaluate the status of this primary food
and nesting source in relation to the
great green macaw (Chosset et al. 2002,
p. 6). According to Costa Rican
legislation (Decree No 25167–MINAE),
the removal or logging of almendro trees
had been illegal in the area between the
San Carlos and Sarapiqui Rivers
(Madriz-Vargas 2004, p. 9). The
objective of the restrictions placed on
extraction of almendro trees was to
increase the number of nesting sites for
the great green macaw and to prevent
PO 00000
Frm 00039
Fmt 4701
Sfmt 4700
60013
the tree from becoming extinct;
however, forest clearings continued to
occur at an alarming rate due to the lack
of resources to protect biological
reserves (Madriz-Vargas 2004, p. 8). For
example, researchers reported in 2003
that, of the 60 great green macaw nests
identified since the great green macaw
conservation project was initiated in
1994, 10 had been cut down by forest
engineers working in forest management
plans (Monge and Chassot 2003, p. 4).
In 2008, Costa Rica’s Supreme Court
stated that MINAE must abstain from
the continuation or initiation of the use,
exploitation, or extraction of the
almendro tree (Chun 2008, p. 113). In
Costa Rica, fines for those who cut
down almendro trees have been
proposed as a measure, although
penalties reportedly have not been
´
instituted (Botero-Delgadillo and Paez
2011, p. 92).
Great Green Macaw Conservation
In the two core areas where the great
green macaw exists in Costa Rica,
conservation activities are under way,
and the breeding populations are being
closely monitored. Quebrada Grande is
a community-operated, 119-ha (294-ac)
reserve in the center of great green
macaw habitat. Additionally, the
National Green Macaw Commission was
formed in 1996 to protect and manage
this species’ habitat. This commission
was formed in response to the severe
decline of the great green macaw
population, and included 13
government agencies, NGOs, and the
´
Sarapiquı Natural Resources
Commission (CRENASA). This
conservation effort was formalized by
Executive Order No. 7815–MINAE of
1999. The group served as an advisory
body to MINAE regarding
environmental issues in the northern
zone of Costa Rica that affect the great
green macaw (Chassot and Monge 2008
in Villate et al. 2008, p. 22).
Conservation efforts are still in progress;
in 2008, a workshop was held to bring
together species experts and government
officials to identify priorities and goals
in order to conserve the species (Monge
et al. 2009, entire).
Additionally, a corridor was created
in 2001, with the goal of maintaining
connectivity and biodiversity between
protected areas in southeastern
Nicaragua, the Protected Conservation
Area Arenal Huetar North (ACAHN),
and Conservation Area of the Central
Volcanic Cordillera (ACCVC) in Costa
Rica. The primary purpose was to
promote the creation of protected
wilderness and encourage habitat
protection necessary to preserve and

asabaliauskas on DSK5VPTVN1PROD with RULES
increase the great green macaw
population (Villate et al. 2008, p. 24).
In 2005, the Maquenque National
Wildlife Refuge (MNWR) was
established primarily to protect
breeding habitat for the great green
macaw. Approximately 43,700 ha
(107,985 ac) of land identified as
potential great green macaw breeding
habitat lies within the boundaries of
MNWR (Chun 2008, p. 113). This region
was targeted because it contains several
large nesting trees used by great green
macaw breeding pairs. MNWR protects
foraging habitat that may be critical
during the great green macaw’s breeding
season. MNWR is within the larger San
Juan La Selva (SJLS) Biological Corridor,
and its goal is specifically to connect
protected areas in southern Nicaragua to
those in central Costa Rica (Chun 2008,
p. 98). However, even in this refuge,
habitat degradation continues to occur.
A RAMSAR (the Convention on
wetlands) report on this refuge (which
is a RAMSAR site), indicated that the
main threats there are agricultural and
forestry activities, which are most
´
´
prevalent near the Colpachı and Manatı
lagoons (RAMSAR 2012, p. 1).
In summary, as of 2002, less than 10
percent of the great green macaw’s
original range was estimated to exist in
Costa Rica (Chosset et al. 2002, p. 6).
The great green macaw greatly depends
on the almendro tree as its primary food
and nesting resource. However, due to
Costa Rica’s complex deforestation
history, the great green macaw remains
imperiled primarily due to habitat
fragmentation, degradation, and habitat
loss. In 2004, a maximum of 35 pairs
were estimated to be breeding in
northern Costa Rica (Chosset et al. 2004,
p. 32), and the population in this
country appears to have increased since
a conservation program and regulatory
mechanisms have been in place. Costa
Rica’s population was estimated to be
approximately 300 birds in 2010
(Chassot 2010 pers. comm. in Hardman
2011, p. 11; Monge et al. 2010, pp. 13,
22). Despite the apparent increase in the
population in Costa Rica, the population
is extremely small and has experienced
significant decline in available habitat
over the past 60 years.
Habitat Degradation
In addition to the historical loss of
habitat, the species continues to face
threats such as habitat degradation. This
species requires a complex suite of plant
species over the course of a year for its
nutritional needs. Pressures to its
habitat such as logging, encroachment,
habitat degradation, and likely other
factors continue within this species’
range. Despite conservation efforts in
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
place, such as conservation awareness
programs, research, and monitoring, the
population has declined significantly
over time and is still only estimated to
be approximately 300 individuals.
Because this species mates for life and
has a small clutch size, the loss of any
one individual can have a significant
effect on the population. Costa Rica has
implemented many environmental laws
in conjunction with conservation efforts
to protect species, particularly the great
green macaw and its habitat. The
situation of this species is still
precarious, and any of the threats acting
on the species, such as habitat loss and
degradation, poaching, or other
unknown factors, could have a
significant effect on the population in
Costa Rica because it is so small, and
because of its life-history characteristics.
The existing regulatory mechanisms, as
implemented, are insufficient in Costa
Rica to adequately ameliorate the
current threats to this species.
Ecuador
As of 2006, the Ecuadorian
Government recognized 31 various legal
categories of protected lands (e.g.,
national parks, biological reserves,
geobotanical reserves, bird reserves,
wildlife reserves, etc.). The amount of
protected land (both forested and nonforested) in Ecuador as of 2006 was
approximately 4.67 million ha (11.5
million ac) (ITTO 2006, p. 228).
However, only 38 percent of these lands
had appropriate conservation measures
in place to be considered protected
areas according to international
standards (i.e., areas that are managed
for scientific study or wilderness
protection, for ecosystem protection and
recreation, for conservation of specific
natural features, or for conservation
through management intervention)
(ITTO 2009, p. 1). Moreover, only 11
percent had management plans, and less
than 1 percent (13,000 ha or 32,125 ac)
had implemented those management
plans (ITTO 2006, p. 228).
In 2004, the Ecuadorian Minister of
the Environment signed a ministerial
decree forming the National Strategy for
the In-Situ Conservation of the
Guayaquil Macaw (Ara a.
guayaquilensis) into law (ProForest
2005, p. 3). The strategy included the
following components to be
implemented within 10 years. Aspects
of this conservation plan, which focuses
on the Cerro Blanco Protected Forest, a
stronghold for great green macaw,
include:
• Applied investigation for the
conservation of the species;
• Management of the conservation
areas where the presence of the
PO 00000
Frm 00040
Fmt 4701
Sfmt 4700
Guayaquil macaw has been confirmed,
incorporating new areas that are critical
for conservation of the species, and
providing connecting corridors between
the areas;
• Reforestation with appropriate tree
species in its habitat;
• Incentives and sustainable
alternatives for communities and private
property owners within its range; and
• Conservation of the Guayaquil
macaw.
Despite the existence of this strategy,
the great green macaw still faces
significant threats in Ecuador (Horstman
2011, p. 12). There are likely fewer than
100 individuals of this subspecies
remaining in Ecuador. Ecuador
recognizes that threats exist to its
natural heritage, not only to this species,
but to all of its wildlife. In 2008,
Ecuador approved Article 71 of its
Constitution, which states, ‘‘Nature has
a right to integrally respect its existence
as well as the maintenance and
regeneration of its vital cycles,
structures, functions and evolutionary
processes.’’ Article 73 also mandates,
‘‘measures of precaution and restriction
for all activities that could lead to the
extinction of species, the destruction of
ecosystems, or the permanent alteration
of natural habitats.’’
Ecuador has made significant strides
in conservation. Ecuador’s Article 103
of Book IV on Biodiversity decreed that:
‘‘It is prohibited, on any day or time of
the year, to hunt species, whether birds
or mammals, that constitute wildlife
and that are listed in Appendix 1 of the
present Record that are qualified as
threatened or endangered. Hunting is
likewise prohibited in certain areas or
zones while the bans are in effect’’
(Monge et al. 2009, p. 256; Unified Text
of the Secondary Legislation of the
Ministry of the Environment). Despite
the recent advances made in
conservation efforts, Ecuador has gone
through periods of devastating habitat
loss and degradation, which affected the
great green macaw’s habitat such that it
only remains in two fragmented and
small areas. It is unclear how
sustainable the remaining habitat is,
particularly because this species has
specialized feeding requirements and
requires a large range to provide its
nutritional needs.
The National Strategy for the In-Situ
Conservation of the Guayaquil Macaw
was revised in 2009. As a result, the first
national census of great green macaw
was conducted in Ecuador in late 2010
(Horstman 2011, pp. 16–17). The Cerro
Blanco Protected Area has been
managed by the Pro-Forest Foundation,
an NGO, for approximately 20 years
(Horstman 2011, unpaginated).

Horstman indicated that, at the Cerro
Blanco Reserve, the resident population
of approximately 15 macaws travels
widely outside of the 6,475-ha (16,000ac) reserve (https://blogs.discovery.com/
animal_news/2009/11/help-forecuadors-great-green-macaws.html,
accessed October 28, 2011). Horstman,
who has worked in this area since the
early 1990s, indicated the need to
establish a conservation corridor
between Cerro Blanco and adjacent
patches of suitable forest, and most are
less than 40.5 ha (100 ac) in size. During
the past 20 years, at least 2,000 ha
(4,942 ac) have been reforested (Monge
et al. 2009, p. 9). Although reforestation
projects have occurred, encroachment is
still occurring (Horstman 2011, p. 12).
Despite conservation efforts and
regulatory mechanisms in place, there is
still limited funding available for
conservation efforts. Encroachment and
other forms of habitat degradation
continue to occur within its habitat (see
Factor A discussion, above). Therefore,
we find that the regulatory mechanisms
are inadequate to ameliorate the loss
and degradation of great green macaw
habitat in Ecuador.
Honduras
The National Conservation and
Forestry Institute (ICF) (formerly the
Protected Areas and Wildlife
Department, established in 1991) is
responsible for regulating natural
resources and management of protected
areas. The National Protected Areas
System includes 17 national parks
created between 1980 and 2007. As of
2009, there were 79 protected areas
(Triana and Arce 2012, p. 1). In 1991,
the Protected Areas and Wildlife
Department (which is now the National
Conservation and Forestry Institute
(ICF)) was designated to manage natural
resources and protected areas (Devenish
et al. 2009, p. 257; Decree no. 74–91,
1991). Prior to 1991, wildlife was
managed by the Honduran Department
of Wildlife and Ecology (RENARE).
Decree 98–2007, the Forest Law of
Honduras, repealed Decree 163–93 of
1993, which contained the Law on
Incentives for Forestation, Reforestation,
and Forest Protection. The Forest Law
sets forth the purposes of the law, and
regulates the use of forestry areas, the
rational and sustainable management of
forestry resources, protected areas, and
wildlife. The law contains definitions
and created a series of administrative
agencies charged with the
implementation of forestry regulations,
including the National Forestry
Consultative Council. This law also
formed the National Forestry Research
System and the National Institute for
VerDate Sep<11>2014

Jkt 238001
Forestry Conservation and Development
(211 provisions; pp. 1–17).
Before the 2007 Forest Law was
approved, at least 38 laws governed the
sector, creating a confusing policy
framework. The situation is further
complicated because, in many cases,
forest tenure (ownership, tenancy, and
other arrangements for the use of
forests) is unclear. Although most forest
is officially state-owned (FAO 2007),
states have little practical authority over
forest management, and individuals
exercise de facto ownership. Corruption
is a barrier to legal logging because it
facilitates illegal operations and creates
obstacles to legal ones (Pellegrini 2011,
p. 18; Rodas et al. 2005, p. 53). Bribes
are extorted from certified community
forestry operations, and, reportedly,
without bribes, transport of legal wood
becomes impossible (Pellegrini 2011, p.
18; Rodas et al., 2005, p. 53).
The new 2007 Forest Law was
supported by environmental groups, but
its implementation was delayed. The
law included the abolition of the
Honduran Forest Development
Corporation (COHDEFOR) (which
received unanimous support), more
resources for enforcement, and harsher
penalties against those who commit
forest-related crimes. Previously, the
director of COHDEFOR and other
political leaders were owners or
employees of logging companies, an
apparent conflict of interest (Pellegrini
2011, p. 20). Also at that time, the army
was involved in enforcement. Out of the
resources that were spent for the
forestry sector, the military absorbed 70
percent without producing any evidence
that enforcement had improved
(Pellegrini 2011, p. 20).
Currently in Honduras, the great green
macaw is believed to exist in eastern
Honduras in suitable habitat distributed
´
´
from Olancho to the Rıo Platano
Biological Reserve, the Tawahka
Biological Reserve, and Patuca National
Park (Monge et al. 2009, p. 39). Its range
encompasses both unprotected and
protected areas; however, timber
exploitation occurs even in areas
designated as protected. This practice
has created conflicts in protected areas
´
´
such as the Rıo Platano Biosphere
Reserve, an area that is considered
critical for its conservation (Lopez and
´
Jimenez 2007, p. 26). Demand for
mahogany, which has been one of the
most extracted species in the area
´
(Lopez and Jimenez 2007, p. 26), has
also put pressure on this species’
habitat. Selective logging creates
openings in forest canopies and changes
the ecosystem dynamics and
composition of plant species. Income
from logging is higher than that earned
PO 00000
Frm 00041
Fmt 4701
Sfmt 4700
60015
for crops and cattle, making logging far
more lucrative for locals. However, after
areas are logged, they become more
accessible and are then often converted
to uses such as crops and cattle grazing.
Indigenous communities have rights
to use many protected areas. Article 107
of the Honduran Constitution protects
the land rights of indigenous people. It
is the duty of the government to create
measures to protect the rights and
interests of indigenous communities in
the country, especially with respect to
the land and forests where they are
settled (Article 346). As an example of
land use by Honduran indigenous
communities, between 15 and 40
percent of the total value of
consumption for two indigenous
Tawahka communities was found to be
derived directly from the forest (Godoy
et al. 2002, p. 404). Struggle over land
rights is a difficult issue for indigenous
communities in Honduras. Logging and
mining are some of the biggest threats
not only to the great green macaw, but
also to the indigenous communities.
Indigenous cultures generally have a
low impact on the forests (Stocks et al.
2007, pp. 1,502–1,503). Because
indigenous communities want their
lands protected for their traditional way
of life, NGOs are working with these
communities to protect reserves in
Honduras, which should ultimately
benefit the great green macaw.
´
´
In 1996, the Rıo Platano Biosphere
Reserve was placed on the ‘‘World
Heritage Site in Danger’’ list, but it was
removed from the list in 2007, due to a
significant improvement in conservation
efforts by NGOs. Several NGOs are
working in this area including the
Mosquitia Paquisa (MOPAWI) and the
´
Rio Platano Biosphere Project (UNEP–
WCMC 2011, p. 5). However,
investigations in 2010 and 2011 indicate
that there are still problems within the
reserve (UNESCO 2011, pp. 1–3).
UNESCO, as recently as 2011,
´
´
conducted a survey in the Rıo Platano
Reserve and found illegal activity
within the core zone (UNESCO 2011,
pp. 1–3). Clearing of land for cattle
grazing and illegal fishing and hunting
along the river is ongoing. The area is
protected by policy by the Department
of Protected Areas and Wildlife, State
Forestry Administration in Honduras.
The reserve management plan,
implemented in 2000, included zoning
and specific plans for conservation
issues. One of the goals of the reserve’s
conservation plan is to integrate local
inhabitants with their environment in
part via sustainable agricultural
practices. This practice has been found
to be a good tool in forest conservation
(Pellegrini 2011, pp. 3–8). The reserve

plan established buffer zones, cultural
zones, and nucleus zones. Indigenous
communities living in the reserve and
buffer zone are allowed to use the
resources within the reserve. The
integration of indigenous populations
plays a large part in the success of the
conservation plan, both inside the
reserve and outside the reserve in the
buffer and peripheral zones (Pellegrini
2011, p. 3; Stocks et al. 2007, pp. 1502–
1503). This reserve also receives some
funding from the World Wildlife Fund
and other private organizations that
assist in the management of the reserve.
However, there are currently no park
guards or any official entity actively
patrolling or guarding the reserve to
enforce restrictions.
There is a complex history concerning
the balance of land rights of indigenous
communities and preservation of habitat
for species such as the great green
macaw. In Honduras, there is a gap
between forestry policy objectives and
the state of forestry. The policy
frameworks exist to manage timber
extraction, but tools are not
implemented (Pellegrini 2011, p. 1).
COHDEFOR had been responsible for
forestry development and enforcement
of laws. The Honduran Government
began to decentralize COHDEFOR
beginning in 1985 (Butler 2012,
unpaginated) due to its ineffectiveness.
As of 2001, the management of
Honduran forests was administered by
´
the Administracion Forestal del Estado
(AFE, Government Forestry
´
Administration), Corporacion
˜
Hondurena de Desarrollo Forestal
(COHEFOR Honduran Forestry
Development Corporation) (Moreno and
Marineros 2001, p. 2). Land use
planning occurs at the national level;
however, identifying the best use of
areas has not been implemented
(Pellegrini 2011, p. 17). In addition,
estimates of illegal logging are
approximately 80 percent of the total
volume extracted for broadleaf and 50
percent for coniferous species (Richards
et al. 2003, p. 1).
Honduras is making progress in
managing its forested resources. In 2010,
Honduras implemented Agreement
number 011–2010 (Ecolex 2011), the
Forestry Reinvestment Fund and
Plantation Development, and its goal is
to recover areas of degraded or denuded
forests. In 2010, Honduras also put into
place Decision No. 31/10, the General
Regulation of Forestry Law, Protected
Areas and Wildlife (Ecolex 2011). This
covers the administration and
management of forest resources,
protected areas, and wildlife. Despite
the progress made in Honduras with
respect to laws and regulatory

mechanisms that affect the great green
macaw and other wildlife, the species
continues to face habitat loss and
degradation in Honduras.
Nicaragua
Nicaragua’s General Environmental
and Natural Resources Law No. 217,
issued in 1996, is considered the legal
framework that defines the standards
and mechanisms in regard to the use,
conservation, protection, and restoration
of the environment and natural
resources in a sustainable manner. It
recognizes the sustainable development
concept. By 2004, Nicaragua had
enacted 10 environmental laws and was
a member of regional and international
environmental agreements (Moreno
2004, p. 9). As of 2004, Nicaragua was
moving towards the consolidation of a
National System of Protected Areas
(SINAP) in order to preserve the
country’s biological wealth (Moreno
2004, p. 9). SINAP consists of National
Protected Areas, Municipal Ecological
Parks, and Private Wildlife Reserves of
‘‘ecological and social relevance at the
local, national, and international level,
defined in conformance with the law,
and designated according to
management categories that permit
compliance with national policies and
objectives of conservation’’ (McGinley
2009, p. 19; Protected Areas
Regulations: Article 3). However, the
overall protection and administration of
SINAP is hindered by an inability to
administer its financial and human
resources (McGinley 2009, p. 20). Of the
72 national protected areas, only 23 had
approved management plans in 2008,
another 19 were in some phase of the
approval process, and 30 protected areas
had no management plan at all
(McGinley 2009, p. 20). Despite
protections in place, enforcement has
been lacking in protected areas, and
poverty continues to be a huge concern
in Nicaragua (FAO 2011, pp. 1–2;
McGinley et al. 2009, p. 16).
Three assessments of the effectiveness
of Nicaragua’s laws and regulations with
respect to wildlife and forestry laws
were recently conducted (Pellegrini
´
2011; McGinley et al. 2009; Castellon et
al. 2008). The first explored the
relationship between forest management
and poverty (Pellegrini 2011). The
research published in 2009 evaluated
Nicaragua’s Tropical Forests and
Biological Diversity (McGinley et al.
2009, entire). The other report evaluated
the effectiveness of Nicaragua’s wildlife
´
trade policies (Castellon.et al. 2008,
entire). In Nicaragua, the organization
responsible for regulation and control of
the forestry sector is the National Forest
Institute (INAFOR), which is under the
PO 00000
Frm 00042
Fmt 4701
Sfmt 4700
Ministry of Agriculture, Livestock and
Forestry (MAGFOR). The other relevant
ministry is the Nicaraguan Ministry of
Environment and National Resources
(MARENA), which supports
conservation awareness programs for
this species. In early 2003, MARENA
created the Municipal Environmental
Unit in order to decentralize
environmental functions. Although a
good legal framework exists in
Nicaragua to protect its natural
resources, there are still on-the-ground
problems that affect this species. For
´
example, in the Indio-Maız Biological
Reserve, one of the strongholds for this
species, each forest guard in the control
posts along the border of the reserve is
responsible for monitoring a stretch of 8
km (5 mi) of the border and an area of
70 km2 (27 mi2) (Rocha 2012, pp. 3–6;
Ravnborg et al. 2006, p. 6). There are
communication and perception
problems that are prevalent within the
reserve that perpetuate the inability to
adequately manage the resources within
the reserve. These resources are used
both legally and illegally by Costa
Ricans who cross the San Juan River
and the local communities who live in
Nicaragua (Rocha 2012, pp. 3–6).
In 2008, the Government of Nicaragua
published a report on the status of its
wildlife laws and mechanisms
(Castellon et al. 2008, entire). It reported
the following findings (p. 9):
• Nicaragua’s current laws are
inadequate to protect and sustain
domestic and international trade in
CITES species. They are unfocused and
lack provisions on habitat degradation
and biological productivity.
• Nicaragua does not have a written
wildlife trade policy or laws to
underpin sustainable species
management in domestic and
international trade. The regulatory
instruments pertaining to sustainable
management of wildlife trade are
relevant and coherent and provide a
basis for the formulation of such a
policy.
• The nonregulatory instruments for
measuring the commercial sustainability
of wildlife trade are rarely used. The
most important of them are: monitoring,
research, education, and information.
• Study of wildlife harvesting shows
that the income from trade in harvested
species goes principally to external
actors, with little or no benefit to rural
communities or populations.
The 2008 study also reported that the
Government of Nicaragua was unable to
find a single case in which the
application of its laws led to actual fines
or penalties for harvesting or trading
banned species (McGinley 2009, p. 22).
It found that nonregulatory instruments

02OCR3
asabaliauskas on DSK5VPTVN1PROD with RULES
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
such as monitoring, research, education,
and information are poorly used in the
oversight of commercial wildlife trade
in Nicaragua (McGinley 2009, p. 22).
Despite these findings, a review
undertaken by the CITES Secretariat
found that the legislation of Nicaragua
has been determined to be sufficient to
properly implement the CITES Treaty
(see discussion below). The country has
made an effort to protect its resources
and is attempting to address the
management of its natural resources.
In addition, specific, targeted
conservation measures are occurring.
An NGO in Nicaragua, with the support
of MARENA, is promoting conservation
of this species. They have initiated a
campaign to educate communities in
part by posting messages on buses on
three highly traveled public routes in
Managua. For example, one message
describes why buying endangered
species as pets is not a good idea; rather,
they should remain in the wild.
Additionally, in 2003, Nicaragua and
Costa Rica participated in the First
Mesoamerican Congress for Protected
Areas. Senior representatives of both
countries discussed ways to explore the
framework of connectivity between
protected areas (Villate et al. 2008, p.
52). As a result, several active
conservation measures for the great
green macaw in Nicaragua are under
way, such as the development of
connected habitat corridors, and the
great green macaw conservation
workshop was held in 2008. In
´
Nicaragua’s Indio-Maız Biological
Reserve, training measures for
monitoring the great green macaw have
been implemented. For example,
technicians associated with Fundacion
del Rio have been trained in great green
macaw research (Chassot et al. 2006, p.
86). The species’ population is
estimated to be only 871 individuals in
Nicaragua and Costa Rica combined
(Monge et al. 2010, p. 21), and pressures
continue to occur to the species and its
habitat. Despite regulatory mechanisms
in place and the existence of many
strategies in Nicaragua to combat threats
to the species such as deforestation,
habitat loss, and poaching for the
wildlife trade, these activities continue.
The impoverished rely strongly on
forest products (Pellegrini 2011, pp. 21–
22). In an attempt to reduce poverty and
at the same time conserve forested areas,
analyses addressing poverty reduction
were conducted prior to 2002.
Strategies, described as Poverty
Reduction Strategy Papers (PRSPs),
recommended approving a forestry law
by 2002 (which actually was approved
at the end of 2003) and addressing
deforestation as a source of ecological
VerDate Sep<11>2014

Jkt 238001
vulnerability. As part of its poverty
reduction strategy, Nicaragua developed
a National Development Plan
(Government of Nicaragua 2005 in
Pellegrini 2011, pp. 21–22), the goal of
which was to strengthen the whole
forestry production chain. However, the
plan was reported not to have been
effectively implemented (Pellegrini
2011, p. 22). The main policy
instruments that set the framework for
forestry were the Forest Law and the
logging ban. The Forest Law establishes
the system of forest management
(Pellegrini 2011, pp. 21–22). The law
includes incentives for sustainable
practices; however, Pellegrini noted that
it is virtually impossible to take
advantage of the law’s provisions
without support by external
organizations such as NGOs (Pellegrini
2011, p. 22; TNC 2007, pp. 3–7).
Nicaragua is focusing efforts on the
restoration and protection of forested
areas, and its goal was to reduce the
deforestation rate from 70,000 ha
(172,974 ac) to 20,000 ha (49,421 ac) per
year by 2010 (McGinley 2009, p. 28).
Recently, the Associated Foresters of
Nicaragua (FORESTAN), in cooperation
with a local NGO, the Instituto de
´
Investigaciones y Gestion Social
(INGES), began an initiative to increase
forest cover. Their goal is to incorporate
conservation and production areas over
5,000 ha (12,355 ac), and more
effectively use commercially valuable
tree species while at the same time
creating permanent jobs (INGES–
FORESTAN 2005 in Sinreich 2009, p.
63). In 2006, a logging ban was put in
place. The ban prohibited extraction of
six species of wood and any logging
operation in protected areas or within
15 km (9 mi) of all national borders, and
it put the army in charge of enforcement
(Government of Nicaragua 2006 in
Pellegrini 2011, p. 23). However,
deforestation rates may have increased
´
even after the ban’s approval (Guzman
2007, pp. 1–2). Although Nicaragua
attempts to manage its natural
resources, it has a large challenge due to
the pressures for its forest resources in
combination with extreme poverty (FAO
2011, p. 1; McGinley et al. 2009, p. 11).
Despite these efforts, pressure on the
great green macaw’s habitat continues.
Panama
In Panama, the great green macaw’s
´
stronghold is believed to be in Darien
National Park, which borders Colombia
(Monge et al. 2009, p. 68; Angehr in litt.
1996 in Snyder et al. 2000, pp. 121–123;
´
Ridgley 1982). The Darien region
encompasses nearly 809,371 ha (2
million ac) of protected areas, including
´
Darien National Park and Biosphere

Reserve, Punta Patino Natural Reserve,
Brage Biological Corridor, and two
reserves for indigenous communities
(TNC 2011, p. 1). Panama’s National
System of Protected Areas (SINAP) is
managed by the National Environmental
Authority (ANAM) and consists of 66
areas, totaling 2.5 million ha (6.18
million ac) (Devenish et al. 2009b, pp.
1–2). Of these, 19 have management
plans, and 36 have been through a
process of strategic planning (ANAM
2006, unpaginated).
ANAM was established in 1998,
through the General Environmental Law
of Panama (Law 41). ANAM is the
primary government institution for
forest and biodiversity conservation and
management. ANAM plans, coordinates,
regulates, and promotes policies and
actions to use, conserve, and develop
renewable resources of the country. Its
mission statement is to guarantee a
healthy environment through the
promotion of rational use of natural
resources, the organization of
environmental management, and the
transformation of Panamanian culture to
improve the quality of life (Virviescas et
al. 1998, p. 2). Law 41 also provides the
framework for SINAP. Environmental
protection in Panama falls under the
jurisdiction of three government
agencies, the Institute for Renewable
Natural Resources, the Ministry of
Agricultural Development, and the
Ministry of Health. There are 17
management categories of protected
areas that were established through
INRENARE’s Resolution 09–94. A later
law, the Forest Law of 2004, established
protections for three types of forest,
which covers 36 percent of the country.
There are political and economic
pressures to develop many areas
(Devenish et al. 2009b, p. 291).
Deforestation, in addition to the lack of
management, and lease periods for these
concessions of 2 to 5 years, have left
only an estimated 250,000 to 350,000 ha
(617,763 to 864,868 ac) of production
forests in Panama (Gutierrez 2001a in
Parker et al. 2004, p. I–10).
Additionally, many protected areas in
Panama lack adequate staff and
resources to patrol the areas or enforce
regulations (Devenish et al. 2009b, p.
291). In 1986, Panama initiated a
´
national forest strategy (Plan de Accion
Forestal de Panama or PAFPAN)
supported by FAO; however the plan
reportedly did not directly tackle the
causes of deforestation. Between 1980
and 1990, concessions for 77,800 ha
(192,248 ac) of production forests were
awarded to 23 companies, for periods
ranging from 2 to 5 years (Parker et al.
2004, p. II–4). In 1994, a new forestry
law was approved, which

institutionalized forest management.
Now, concessions exist only in the
´
Darien Province (Parker et al. 2004, p.
II–4). Between 1992 and 2000, the
´
Darien Province was one of Panama’s
provinces that experienced the greatest
declines (11.5 percent) in forest cover
(Parker et al. 2004, p. 32). However,
there are activities in place to combat
these pressures. For example, a training
program exists to increase capacity in
issues such as planning, geographic
information systems, sustainable
tourism, trail construction and
management for park staff, community
groups, and other stakeholders in the
protected area system.
´
Darien National Park
´
Darien National Park extends along
about 80 percent of the PanamaColombia border and includes part of
the Pacific coast. The area has been
under protection since 1972, with the
´
establishment of Alto Darien Protection
Forest. It was declared a national park
in 1980. The park is zoned as a strictly
protected core zone of over 83,000 ha
(205,097 ac). Another zone consists of
180,000 ha (444,789 ac) and contains
indigenous Indian populations that have
maintained their traditional way of life
and culture. Approximately 8,000 ha
(19,768 ac) is designated for tourism and
environmental education, and the last
zone is described as an ‘‘inspection
zone’’ which is 40-km (25-mi) wide, and
spans the Panama-Colombia border. The
´
Darien forests are threatened from
logging, agriculture expansion, burning,
and hunting and gathering (TNC 2011,
pp. 1–2; Monge et al. 2009, p. 68). Other
threats to forest in the region include
the development of projects such as
dams and highways (Parker et al. 2004,
pp. II–7–II–8).
´
Since 1986, the Asociacion Nacional
para la Conservacion de la Naturaleza
(ANCON) has been actively involved in
conservation of the park in conjunction
with INRENARE, the World Wildlife
Fund, and other conservation entities.
In 1995, a biodiversity conservation
project was initiated. The project’s goal
was to involve local communities in
conservation and sustainable use
activities, and was funded by the United
Nations Environment Programme
(UNEP) and the Global Environment
Facility. The Nature Conservancy (TNC)
is also active in conservation efforts in
this area through its Parks in Peril
program (TNC 2011, pp. 1–2).
Panama has also initiated
reforestation efforts. For example,
beginning in the 1960s, Panama began
to plant Pinus caribaea (pine species) in
degraded areas of the Cordillera of the
central region. Additionally, in 1992, a
VerDate Sep<11>2014

Jkt 238001
law was passed to provide incentives for
the establishment of plantations;
however, these were mainly exotic
species (Parker et al. 2004, p. III–6).
Panama is now implementing
reforestation and timber production
projects that focus on native species.
This initiative is known as the ‘‘Native
Species Reforestation Project’’ (Proyecto
´
de Reforestacion con Especies Nativas;
PRORENA) (Schmidt 2009, p. 10).
Forestry managers have realized that, in
some cases, native species are better
adapted and perform better than
introduced species. Since 2001, the joint
Native Species Reforestation Project
between the Smithsonian Tropical
Research Institute and the Yale School
of Forestry has conducted ongoing
research on trees native to Panama. The
almendro tree, which is vital to the great
green macaw’s habitat, has been the
subject of research projects in Panama
because of its high commercial value
(Schmidt 2009, p. 17). Despite efforts to
reduce deforestation activities,
management problems remain. A study
conducted in 2004 suggested that the
Forestry Department needs increased
autonomy, funding, and staff, and a
more appropriate mandate (Parker et al.
2004, pp. 10–11). The study suggested
that strengthening the Parks and
Wildlife Service through increased
staffing and resources would enable
them to protect and manage protected
areas (Parker et al. 2004, pp. 10–11).
In summary, Panama has a suite of
environmental laws in place, and
conservation measures are being
implemented by the government in
collaboration with some NGOs.
However, there is very little information
available about the great green macaw in
Panama (Monge et al. 2009, p. 68), and
the information indicates that this
species continues to face pressures to its
habitat. Despite Panama’s participation
in conservation initiatives and Panama’s
regulatory mechanisms in place, there
are still significant pressures for
resources in the great green macaw’s
habitat.
International Wildlife Trade (CITES)
The CITES Treaty requires Parties to
have adequate legislation in place for its
implementation. A complete discussion
on CITES is found under Factor D for
the military macaw. Within the recent
past (since 2000), 261 live great green
macaws were reported to have been
imported by CITES reporting countries,
and none of these live specimens were
reported as wild origin (UNEP–WCMC
CITES Trade Database, accessed
December 8, 2011). Under CITES
Resolution Conference 8.4 (Rev. CoP15),
and related decisions of the Conference
PO 00000
Frm 00044
Fmt 4701
Sfmt 4700
of the Parties, the National Legislation
Project evaluates whether Parties have
adequate domestic legislation to
successfully implement the Treaty
(CITES 2011a). In reviewing a country’s
national legislation, the CITES
Secretariat evaluates factors such as
whether or not a Party:
• Has domestic laws that prohibit
trade contrary to the requirements of the
Convention;
• Has penalty provisions in place for
illegal trade, and has designated the
responsible Scientific and Management
Authorities; and
• Provides for seizure of specimens
that are illegally traded or possessed.
The CITES Secretariat determined
that the legislations of Colombia, Costa
Rica, Honduras, Nicaragua, and Panama
are sufficient to properly implement the
Treaty (https://www.cites.org, SC58 Doc.
18 Annex 1, p. 1). These governments
were determined to be in Category 1,
which means they meet all the
requirements to implement CITES.
Ecuador was determined to be in
Category 2, with a draft plan, but not
enacted (https://www.cites.org, SC59
Document 11, Annex p. 1, accessed
December 16, 2011). This means the
CITES Secretariat determined that the
legislation of Ecuador meets some, but
not all, of the requirements for
implementing CITES. Based on the
limited amount of reported international
trade for this species, particularly in
wild-caught specimens, the range
countries, including Ecuador, have
effectively controlled legal international
trade of this species. Therefore, we find
CITES is an adequate regulatory
mechanism.
Summary of Factor D
In the range countries for this species,
we recognize that conservation activities
are occurring, and each country has
enacted laws with the intent of
protecting its species and habitat. For
example, in 2002, the San Juan—La
Selva Biological Corridor, an area of
60,000 ha (148,263 ac), was
implemented to protect the nesting
places and migration flyway of the great
green macaw in Costa Rica, as far as the
Nicaragua border, where very little is
known about the species. However,
most of the suitable habitat is restricted
to protected areas in clustered locations.
Oliveira et al. (2007) found that forests
in conservation units were four times
better at protecting against deforestation
than unprotected areas (Oliveira et al.
2007, p. 1,235). Despite regulatory
mechanisms established by this species’
range countries and despite the species’
existence in areas designated as
protected, this species has experienced
E:\FR\FM\02OCR3.SGM
02OCR3
Federal Register / Vol. 80, No. 191 / Friday, October 2, 2015 / Rules and Regulations
threats such that its populations are
now so small that any pressure has a
more significant effect. Parks, without
management, are often insufficient to
adequately protect the species.
The information available with
respect to the species’ population
numbers is extremely limited in its
range countries, and the populations of
this species in these countries all likely
range from a few individuals to a few
hundred individuals (Botero-Delgadillo
´
and Paez 2011, p. 91; Monge et al. 2010,
p. 22; Monge et al. 2009, p. 256). The
populations are all in relatively
disconnected areas. Its suitable habitat
has been severely constricted due to
deforestation. In all of the range
countries, there is clear evidence of
threats to this species due to activities
such as habitat destruction and
degradation, and poaching, and there is
decreased viability due to small
population sizes, despite the laws and
regulatory mechanisms in place. Given
that the species’ habitat continues to be
fragmented and degraded, it is unlikely
that any conservation measures are
adequately mitigating the factors
currently acting on the species.
Based on the best available
information, despite protections in
place by the respective governments, we
find that the existing regulatory
mechanisms are either inadequate or
inadequately enforced to protect the
species or to mitigate ongoing habitat
loss and degradation, poaching, and
severe population declines. Habitat
conservation measures within these
range countries do not appear to be
sufficient to adequately mitigate future
habitat losses. This is due to a suite of
factors, such as high rates of poverty in
the range of the great green macaw and
subsequent pressures for resources, and
conflicting management goals (such as
economic development and protection
of its resources) of its range countries.
Therefore, we find that the existing
regulatory mechanisms are inadequate
to mitigate the current threats to the
continued existence of the great green
macaw throughout its range.

E. Other Natural or Manmade Factors
Affecting Its Continued Existence
Small Population Size and Stochastic
Events
There have been few quantitative
studies of great green macaw
´
populations (Botero-Delgadillo and Paez
2011, p. 91; Monge et al. 2010, p. 12;
Monge et al. 2009.). In 2009, the
combined estimate for Costa Rica and
Nicaragua was 871 individuals (Monge
et al. 2010, p. 21), and the estimate for
Ecuador was fewer than 100 (Horstman
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
2011, p. 17). There are no current
population estimates for Panama,
Honduras, and Colombia, but the global
population is believed to be fewer than
3,700 individuals (Monge et al. 2009,
pp. 68, 79, 213). Small, declining
populations can be especially
vulnerable to environmental
disturbances such as habitat loss (Harris
and Pimm 2008, pp. 163–164; O’Grady
2004, pp. 513–514; Brooks et al. 1999,
pp. 1,146–1,147). In Costa Rica, the
great green macaw has been eliminated
from approximately 90 percent of its
former range, and one estimate
indicated that there were only 275 birds
remaining in 2010 (Chassot 2010 pers.
comm. in Hardman 2011, p. 11).
Isolated populations are more likely to
decline than those that are not isolated
(Davies et al. 2000, p. 1,456), as
evidenced by the Ecuadorian
population. Additionally, the great
green macaw’s restricted range,
combined with its small population size
and low prospect for dispersal (Chosset
et al. 2004, p. 32), makes the species
particularly vulnerable to the threat of
any adverse natural (e.g., genetic,
demographic, or stochastic) and
manmade (e.g., habitat alteration and
destruction) events that could destroy
individuals and their habitats.
The government of Costa Rica, in
cooperation with Zoo Ave Wildlife
Conservation Park, located in Garita de
Alajuela, has participated in a captive
bird breeding program (Herrero 2006,
pp. 2–3) since 1994. Some of the birds
produced have been released in
protected areas. However, captive
breeding is a controversial issue, mainly
due to the reintroduction of individuals.
One of the concerns is that the
reintroduced birds introduce infectious
diseases (which may be in dormant
phase for a period of time) into the wild
(Brightsmith et al. 2006 in Herrero 2006,
pp. 2–3).
There are multiple features of this
species’ biology and life history that
affect its ability to respond to habitat
loss and alteration, as well as to
stochastic environmental events. Due to
its current restricted distribution and
habitat requirements, stochastic events
could further isolate individuals. An
example of a stochastic event impacting
the species occurred in 2010, and the
death of several nestlings was recorded
(Chosset and Arias 2010, p. 15). One
nestling fell out of a tree, and, in
another case, a branch fell on a nestling
while it was actually in the nest and it
died (Chosset and Arias 2010, p. 15).
Losses such as these can have a
significant effect on the population.
Additionally, limited available suitable
habitat makes it difficult for the species
PO 00000
Frm 00045
Fmt 4701
Sfmt 4700
60019
to recolonize isolated habitat patches,
which presently exist in a highly
fragmented state. This, in combination
with the species’ nutritional needs,
results in the species requiring large
home ranges.
Border Conflict
One of the difficulties in the
conservation of this species that may
not be readily apparent is border
conflict. For example, at the border of
Nicaragua and Costa Rica, despite
cooperation efforts; conflict continues
(U.S. Department of State 2012,
unpaginated; Berrios 2004, entire). The
Nicaraguan-Costa Rican border is one of
the most conflict-heavy frontiers in
Central America (Lopez and Jimenez
2007, p. 21). Migration issues,
navigation rights in border rivers, border
delineation, and cultural differences all
affect these countries’ relations (Lopez
and Jimenez 2007, p. 21). Additionally,
this area has historically experienced
exploitation of its natural resources.
Since the beginning of last century,
foreign companies have engaged in
logging, rubber extraction, and mining
(Lopez and Jimenez 2007, pp. 24–25).
After these resources were depleted and
these activities were no longer
profitable, some companies left, leaving
behind harmful environmental impacts
(Lopez and Jimenez 2007, pp. 24–25).
These activities have resulted in
polluted rivers, high levels of
sedimentation in coastal lagoons, and
deforested areas (Lopez and Jimenez
2007, pp. 24–25). These activities all
subsequently affect the habitat of the
great green macaw.
Deforestation in Nicaragua has a
complex history. After a civil war
throughout the 1980s, land tenure
policies inadvertently encouraged
farming techniques that led to
deforestation, soil erosion, and general
land degradation (Sinreich 2009, p. 11).
Later, during the 1990s, COHDEFOR
opened up timber extraction
opportunities to local community
organizations, mainly cooperatives, to
help mitigate the economic situation for
local people. Licenses allowed the use
of fallen wood and timber extraction for
sale at local markets. However, a study
conducted between 1998 and 2000
found that local groups had extracted an
enormous amount of timber and there
´
´
was no monitoring (Colındres and Rubı
2002). Although the government offered
support to communities in its border
regions during the period of 1994–1999,
tensions continue to affect the Bosawas
region of Nicaragua, one of the areas
believed to contain a great green macaw
´
population (Lopez and Jimenez 2007, p.
26). Land rights disputes continue to
E:\FR\FM\02OCR3.SGM

occur in Bosawas, and land use rights
are often unclear. Although the
Government of Nicaragua is attempting
to manage these issues (Pellegrini 2011,
p. 21), conflict and practices that
degrade the great green macaw’s habitat
persist both in the Bosawas Reserve and
´
the Indio-Maız Biological Reserve.
asabaliauskas on DSK5VPTVN1PROD with RULES
Climate Change
Our analysis under the ESA includes
consideration of ongoing and projected
changes in climate (see discussion
under the military macaw). The 2008
workshop in Costa Rica addressed
environmental disasters in the
evaluation and assessment of the great
green macaw, although climate change
was not specifically addressed.
Researchers describe environmental
disasters as events that occur
infrequently but that can drastically
affect reproduction or survival. Monge
et al. reported that in Costa Rica, the
number of active nests in 2000 was well
below the average of other years. The
researchers linked this with the strong
˜
El Nino event that occurred during
1997–1998 (Monge et al. 2009, p. 149).
The researchers stated that in the last 50
˜
years there were two major El Nino
events, and, therefore, one would expect
that in 100 years there would be four
events of this nature, which could
subsequently reduce reproduction by 30
percent (Monge et al. 2009, p. 149).
However, this correlation between the
low number of active nests and the El
˜
Nino event is not strongly supported,
nor do we have supporting evidence
that this is directly related to climate
change. We are not aware of any
information that indicates that climate
change threatens the continued
existence of the great green macaw.
Summary of Factor E
A species may be affected by more
than one threat. Impacts typically
operate synergistically, and are
particularly evident when small
populations of a species are decreasing.
Initial effects of one threat factor can
exacerbate the effects of other threat
factors (Laurance and Useche 2009, p.
´
1,432; Gilpin and Soule 1986, pp. 25–
26). Further fragmentation of
populations can decrease the fitness and
reproductive potential of the species,
which can exacerbate other threats. Lack
of a sufficient number of individuals in
a local area or a decline in their
individual or collective fitness may
cause a decline in the population size,
even with suitable habitat patches.
Within the preceding review of the five
factors, we have identified multiple
threats that have interrelated impacts on
this species. Thus, the species’
VerDate Sep<11>2014
21:34 Oct 01, 2015
Jkt 238001
productivity may be reduced because of
any of these threats, either singularly or
in combination. These threats occur at
a sufficient scale such that they are
affecting the status of the species now
and in the future.
This species’ current range is highly
restricted and severely fragmented. Each
breeding pair requires a large home
range to meet its nutritional
requirements; it is a large macaw, and
its sources of food are becoming scarcer
and farther apart, which requires more
energy consumption to locate. The
susceptibility to extirpation of limitedrange species can occur for a variety of
reasons, such as when a species’
remaining population is already too
small or its distribution too fragmented
such that it may no longer be
demographically or genetically viable.
The species’ small and declining
population size, reproductive and lifehistory traits, and highly restricted and
severely fragmented range together
increase the species’ vulnerability to
any other stressors. Based on the above
evaluation, we conclude that the effects
of isolation and its small, declining
population size, combined with the
threats of continued fragmentation and
isolation of suitable forest habitats, pose
a threat to the great green macaw.
Finding and Status Determination for
the Great Green Macaw
Although precise quantitative
estimates are not available, the best
available information suggests that
populations of great green macaws have
substantially declined, and this species
likely persists at greatly reduced
numbers relative to its historical
abundance. The factors that threaten the
survival of the great green macaw are:
(A) Habitat destruction, fragmentation,
and degradation; (B) Overutilization via
poaching; (D) inadequacy of regulatory
mechanisms to reduce the threats to the
species; and (E) small population size
and isolation of remaining populations.
The direct loss of habitat through
widespread deforestation and
conversion of primary forests to human
settlement and agricultural uses has led
to the fragmentation of habitat
throughout the range of the great green
macaw and isolation of the remaining
populations. The species has been
locally extirpated in many areas and has
experienced a significant reduction of
suitable habitat. The current suitable
habitat in Costa Rica is now less than 10
percent of its original suitable habitat
(Chosset et al. 2004, p. 38). This species
exists generally in small and fragmented
populations, and in many cases, the
population is so small that intense
monitoring and management of the
PO 00000
Frm 00046
Fmt 4701
Sfmt 4700
population is under way. The San Juan–
La Selva Biological Corridor was
established to connect forest patches
and join 20 protected areas (Chosset and
Arias 2010, p. 5) specifically to preserve
habitat for this species.
We have very little information about
the species in many parts of its range
´
(Botero-Delgadillo and Paez 2011, p. 91;
Monge et al. 2009, p. 68). In 2008,
experts from this species’ range
countries attended a conference to
evaluate the viability of its populations
and its habitat (Monge et al. 2009,
entire). In general, they concluded that
populations are viable but they still face
threats. The workshop also addressed
goals for the conservation of the species;
in some parts of its range, conservation
efforts are intensive. Based on our
review of the best available scientific
and commercial information pertaining
to the five factors, the threats to the
species are generally consistent
throughout its range. In many of the
range countries, its populations are very
small, and specific information about
the status of the species is not available
in all countries. However, habitat loss
and degradation is prevalent throughout
this species’ range; its suitable habitat
has severely contracted, and habitat loss
is likely to continue into the future due
to pressures for resources. Poaching is
known to occur within many parts, if
not all parts, of its range. Despite
conservation awareness programs,
poverty is prevalent within the range of
the species, and the species is quite
valuable commercially, so poaching
continues to occur. We do not find that
the effects of current threats acting on
the species are being ameliorated by
regulatory mechanisms. Therefore, we
find that listing the great green macaw
as endangered is warranted throughout
its range, and we propose to list the
great green macaw as endangered under
the ESA.
Available Conservation Measures
Conservation measures provided to
species listed as endangered or
threatened under the ESA include
recognition, requirements for Federal
protection, and prohibitions against
certain practices. Recognition through
listing results in public awareness, and
encourages and results in conservation
actions by Federal and State
governments, private agencies and
interest groups, and individuals.
The ESA and its implementing
regulations set forth a series of general
prohibitions and exceptions that apply
to all endangered and threatened
wildlife. These prohibitions, at 50 CFR
17.21 and 17.31, in part, make it illegal
for any person subject to the jurisdiction

any endangered wildlife species. It also
is illegal to possess, sell, deliver, carry,

Certain exceptions apply to agents of the
Service and State conservation agencies.
Permits may be issued to carry out
otherwise prohibited activities
involving endangered and threatened
wildlife species under certain
circumstances. Regulations governing
permits for endangered species are
codified at 50 CFR 17.22. With regard to
endangered wildlife, a permit may be
issued for the following purposes: For
scientific purposes, to enhance the
propagation or survival of the species,
and for incidental take in connection
with otherwise lawful activities. For
threatened species, a permit may be
issued for the same activities, as well as
zoological exhibition, education, and
special purposes consistent with the
ESA.

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), are listing
the military macaw (Ara militaris) and the great green macaw (Ara
ambiguus) as endangered under the Endangered Species Act of 1973, as
amended (ESA). These species are both endemic to Central and South
America. Despite conservation efforts, these species' populations are
in decline, primarily due to habitat loss, fragmentation, and
degradation; small population size; poaching; and regulatory mechanisms
that are inadequate to ameliorate these threats throughout their
ranges.
DATES: This rule becomes effective November 2, 2015.
ADDRESSES: This final rule is available on the Internet at https://www.regulations.gov and comments and materials received, as well as
supporting documentation used in the preparation of this rule, will be
available for public inspection, by appointment, during normal business
hours at: U.S. Fish and Wildlife Service; 5275 Leesburg Pike, Falls
Church, VA 22041.

SUPPLEMENTARY INFORMATION:
Executive Summary
I. Purpose of the Regulatory Action
On January 31, 2008, the Service received a petition dated January
29, 2008, from Friends of Animals, represented by the Environmental Law
Clinic, University of Denver, Sturm College of Law, requesting that we
list 14 parrot species under the Endangered Species Act of 1973, as
amended (ESA or Act; 16 U.S.C. 1531 et seq.). As part of a court-
approved settlement agreement, the Service agreed to submit a
determination as to whether the petitioned action is warranted, not
warranted, or warranted but precluded by other listing actions for the
military macaw (Ara militaris) and the great green macaw (Ara ambiguus)
to the Federal Register by June 30, 2012. On July 6, 2012, the Service
published a proposed rule (77 FR 40172) to add the military macaw and
great green macaw as endangered species to the Federal List of
Endangered and Threatened Wildlife. This final rule completes the
listing process for these species.
II. Summary of the Major Provisions of the Regulatory Action
We are listing the military macaw (Ara militaris) and the great
green macaw (Ara ambiguus) as endangered species under the Act. We are
finalizing this action primarily because of the effects of poaching,
habitat loss, fragmentation, and degradation on their populations;
their small and declining population sizes; and inadequate regulatory
mechanisms to ameliorate the threats to the species throughout their
ranges.
In this final rule, we used public comments and peer review to
inform our final determination, as required under the Act. When we
published the proposed rule on July 6, 2012 (77 FR 40172), we opened a
60-day comment period on the proposed listing for these species. During
the comment period, we sought comments from independent specialists
(peer reviewers) on the specific assumptions and conclusions in our
listing proposal to ensure that the designation of these species as
endangered is based on scientifically sound data, assumptions, and
analyses. In addition, we sought comments from interested parties and
the public. We considered all comments and information received during
the comment period. In this final rule, we present and respond to peer
reviewer and public comments. This rule finalizes the protections
proposed for these two foreign bird species as endangered species,
following careful consideration of all comments we received during the
public comment period.
III. Costs and Benefits
Section 4(b)(1)(A) of the ESA directs that determinations as to
whether any species is an endangered or threatened species must be made
``solely on the basis of the best scientific and commercial data
available.'' Further, this action is not a ``significant'' regulatory
action under Executive Order 12866. Therefore, we have not analyzed its
costs or benefits.
Background
Section 4(b)(3)(B) of the ESA (16 U.S.C. 1531 et seq.) requires
that, for any petition to revise the Federal Lists of Endangered and
Threatened Wildlife and Plants that contains substantial scientific or
commercial information that listing the species may be warranted, we
make a finding within 12 months of the date of receipt of the petition
(``12-month finding''). In this finding, we determine whether the
petitioned action is: (a) Not warranted, (b) warranted, or (c)
warranted, but immediate proposal of a regulation implementing the
petitioned action is precluded by other pending proposals to determine
whether species are endangered or threatened, and expeditious progress
is being made to add or remove qualified species from the Federal Lists
of Endangered and Threatened Wildlife and Plants. Section 4(b)(3)(C) of
the ESA requires that we treat a petition for which the requested
action is found to be warranted but precluded as though resubmitted on
the date of such finding, that is, requiring a subsequent finding to be
made within 12 months. We must publish these 12-month findings in the
Federal Register.
In this document, we announce that listing these two species as
endangered species is warranted, and we are adding these two species to
the Federal List of Endangered and Threatened Wildlife in title 50 of
the Code of Federal Regulations.
Petition History
On January 31, 2008, the Service received a petition dated January
29, 2008, from Friends of Animals, as represented by the Environmental
Law Clinic, University of Denver, Sturm College of Law, requesting that
we list 14 parrot species under the ESA. The petition clearly
identified itself as a petition and included the requisite information
required in the Code of Federal Regulations (50 CFR 424.14(a)). On July
14, 2009 (74 FR 33957), we published a 90-day finding in which we
determined that the petition presented substantial scientific and
commercial information to indicate that listing may be warranted for 12
of the 14 parrot species.
In our 90-day finding on this petition, we announced the initiation
of a status review to list as endangered or threatened under the ESA
the following 12 parrot species: Blue-headed macaw (Primolius couloni),
crimson shining parrot (Prosopeia splendens), great green macaw (Ara
ambiguus), grey-
[[Page 59977]]
cheeked parakeet (Brotogeris pyrrhoptera), hyancith macaw
(Anodorhynchus hyacinthinus), military macaw (Ara militaris),
Philippine cockatoo (Cacatua haematuropygia), red-crowned parrot
(Amazona viridigenalis), scarlet macaw (Ara macao), white cockatoo
(Cacatua alba), yellow-billed parrot (Amazona collaria), and yellow-
crested cockatoo (Cacatua sulphurea). We initiated the status review to
determine if listing each of the 12 species is warranted, and initiated
a 60-day public comment period to allow all interested parties an
opportunity to provide information on the status of these 12 species of
parrots. The public comment period closed on September 14, 2009.
On July 21, 2010, a settlement agreement was approved by the Court
(CV-10-357, D. DC), in which the Service agreed to submit to the
Federal Register by July 29, 2011, September 30, 2011, and November 30,
2011, determinations whether the petitioned action is warranted, not
warranted, or warranted but precluded by other listing actions for no
less than 4 of the petitioned species on each date.
On August 9, 2011, the Service published in the Federal Register a
12-month status review finding for the crimson shining parrot (a
finding that listing was not warranted) and a proposed rule for the
following three parrot species: Philippine cockatoo, white cockatoo,
and yellow-crested cockatoo (76 FR 49202).
On October 6, 2011, we published a 12-month status review finding
for the red-crowned parrot (76 FR 62016); on October 11, 2011, we
published a 12-month status review and proposed rule for the yellow-
billed parrot (76 FR 62740); and on October 12, 2011, we published a
12-month status review for the blue-headed macaw and grey-cheeked
parakeet (76 FR 63480).
On September 16, 2011, an extension to the settlement agreement was
approved by the Court (CV-10-357, D. DC), in which the Service agreed
to submit a determination for the remaining four petitioned species to
the Federal Register by June 30, 2012.
On July 6, 2012, the Service published in the Federal Register a
12-month status review finding and proposed rule for the four following
parrot species: Great green macaw and the military macaw (77 FR 40172),
hyacinth macaw (77 FR 39965), and the scarlet macaw (77 FR 40222).
Upon publication in the Federal Register on July 6, 2012, of the
12-month status review finding and proposed rule for these species (77
FR 40172), we initiated a 60-day public comment period, which ended on
September 4, 2012. Following publication of the proposed rule, we
implemented the Service's peer review process and during the 60-day
comment period, solicited scientific and commercial information on the
species from all interested parties.
Previous Federal Actions
In our proposed rule, published July 6, 2012 (77 FR 40172), we
announced that listing the military macaw and the great green macaw as
endangered was warranted, and we issued a proposed rule to add these
two species to the Federal List of Endangered and Threatened Wildlife.
The comment period ended on September 4, 2012; we received 59 comments
from the public.
In response to requests received during the public comment period,
we reopened another public comment period on February 21, 2013, which
ended on April 22, 2013 (78 FR 12011). During the second comment period
(see https://www.regulations.gov, docket number FWS-R9-ES-2011-0101), we
received 25 more comments on these two macaw species and on the
hyacinth macaw; however, only one submission provided substantive
information. All comments, including names and addresses of commenters,
have become part of the administrative record and are available at
https://www.regulations.gov, docket numbers FWS-R9-ES-2011-0101 and FWS-
R9-ES-2012-0013.
Summary of Comments and Recommendations
We base this finding on a review of the best scientific and
commercial information available, including all information received
during the public comment period. In the September 4, 2012, proposed
rule, we requested that all interested parties submit information that
might contribute to development of a final rule. On February 21, 2013,
we reopened the public comment period where we again requested that all
interested parties submit information that might contribute to
development of a final rule. We also contacted appropriate scientific
experts and organizations and invited them to comment on the proposed
listings. We received comments from four individuals; one of which was
from a peer reviewer.
Peer Reviewer Comments
(1) Comment: One peer reviewer provided information on military
macaw population surveys confirming the presence of 100 macaws in the
Tehuacan-Cuicatlan Biosphere Reserve in Mexico.
Our Response: We have reviewed the additional literature and
incorporated the new information into our finding. Although the new
information has been incorporated into the final rule, the new survey
provided did not change our finding that the military macaw meets the
definition of an endangered species. The species' overall population
remains small and fragmented despite additional macaws being observed
in this one location, and the species is still at risk of extinction
due to habitat loss, poaching, and small population size.
Public Comments
(2) Comment: Several commenters expressed concerns about the
potential impact the listings might have on their business.
Our Response: We acknowledge that there may be impacts to different
entities involved in captive breeding of great green and military
macaws. However, Section 4(b)(1)(A) requires listing decisions to be
based solely on the best scientific and commercial data available, as
it relates to the five listing factors in section 4(a)(1) of the Act.
Therefore, the Service did not consider the impacts on business in its
listing determination.
(3) Comment: Some commenters suggest that the Service is using
outdated information when making the determination for the rule.
Our Response: The Service is required by the Act to make
determinations solely on the basis of the best scientific and
commercial data available. We based the proposed rule on all the
information we received following the initiation of the 12-month status
review for the military and great green macaw, as well as all of the
information we found while conducting our own research. The information
we use depends on field research and our ability to acquire that
information. At the time of the publishing of the proposed rule, the
information we compiled was considered the best available information.
After publishing the proposed rule, emerging information on the great
green and military macaw became available. We reviewed that
information, as well as additional information submitted by the public,
including more recent information and studies from a species expert and
conservation organizations within the great green and military macaw's
range countries. Non-English literature was professionally translated,
analyzed, and is cited in this document. The information we received
and subsequently reviewed did not change any of our findings, but
rather further supported our conclusions. That
[[Page 59978]]
information has been incorporated into this final rule.
(4) Comment: Some commenters, while not opposed to the listing of
the species, asked for a special rule under section 4(d) of the Act
(also called a ``4(d) rule'') that would allow ownership and interstate
trade of the species to occur without obtaining a permit under the Act.
Our response: Ownership of a listed species is not prohibited by
the Act and, therefore, does not require a permit. Because we
determined that listing the great green and military macaws as
endangered species under the Act is appropriate, we are not able to
develop a 4(d) rule for this species. Section 4(d) of the Act allows
the Service to develop a special rule to apply the prohibitions of
section 9 or to provide measures that are necessary and advisable to
provide for the conservation of threatened species only. A special rule
cannot be promulgated for a species that is listed as endangered under
the Act. The sale; offer for sale; and delivery, receipt, carrying,
transport, or shipment in interstate or foreign commerce in the course
of a commercial activity is prohibited. That said, not all interstate
trade is prohibited under the ESA. Interstate transfer of animals that
are not for sale, offered for sale, or in the course of a commercial
activity is not prohibited.
We thank all the commenters for their interest in the conservation
of this species and thank those commenters who provided information for
our consideration in making this listing determination. Under section
4(b) of the Act, the Service is required to make listing determinations
solely on the basis of the best scientific and commercial data
available after conducting a review of the status of the species. When
we published our proposed rule, we opened a public comment period
during which we requested any additional information on the great green
and military macaw. In making this listing determination, we reviewed
the best available scientific and commercial information, contacted
species experts, and searched for the most current information on these
species with due diligence. Therefore, we have obtained and considered
the ``best scientific and commercial data available'' in our listing
determination. After careful consideration, we conclude that these
species meet the definition of an endangered species under the Act.
Species Information for the Military Macaw
Taxonomy
The military macaw (Ara militaris, Linnaeus 1766) is in the
Psittacidae family and is also known as ``guacamaya verde,''
``parava,'' and ``ravine parrot.'' Three subspecies of military macaw
have been proposed and are recognized by some: Ara militaris bolivianus
(Reichenow 1908), Ara militaris mexicanus (Ridgway 1915), and Ara
militaris militaris (Linnaeus 1766). Avibase, a database of all birds
of the world maintained by Bird Studies Canada, and the Integrated
Taxonomic Information System (ITIS) both recognize subspecies (https://www.itis.gov and https://avibase.bsc-eoc.org/avibase.jsp, accessed
August 30, 2011). The range of A. m. bolivianus is thought to be in
Bolivia and northwestern Argentina. The range of A. m. mexicanus is
thought to be restricted to Mexico.
Because it is a strong flyer (it has been observed traveling up to
20 kilometers (km) (12 miles [mi]) per day) and it is a semi-migratory
species, the physical similarities suggest that seemingly isolated
populations may be in contact (Juniper and Parr 1998, p. 423), and,
therefore, their populations may be exchanging genetic material.
For the purpose of this rule, we are addressing the military macaw
at the species level. Therefore, we are listing the military macaw
species as an endangered species, which includes all subspecies.
Description
The military macaw is an extremely vocal species; it is described
as being very noisy and is known to shriek (Birdlife International
(BLI) 2011, p. 1). It is a large macaw (70 centimeters or 27.5 inches
in length) and is vibrant in color. It has dark lime-green feathers
mixed with blue flight feathers that are olive-colored underneath. Its
forehead is red, and it has a bare white facial area and a black bill.
Its lower back is blue; its tail is red and blue. The southernmost
population in Bolivia, which extends into Argentina, exhibits reddish
brown on their throats and cheeks (Juniper and Parr 1998, p. 423). This
species is often confused with the great green macaw (Ara ambiguus).
The great green macaw is very similar in appearance to the military
macaw, but the military macaw has more prominent blue tinge on its hind
neck, is smaller, and has darker plumage. These two species are
separated geographically.
Habitat and Life History
Military macaws nest in tree cavities and cliffs. Cliff-nesting
parrots, such as the military macaw, also nest colonially (in groups)
(Bonilla-Ruz et al. 2007a, pp. 730-731). Cliff cavities located in
ravines used by this species have been documented 25 and 30 meters (m)
(82 to 98 feet (ft)) above ground (Arcos-Torres and Solano-Ugalde 2008,
p. 71). Tree cavities used by this species have been observed to be 18
m (60 ft) above ground and are approximately 75 cm (29.5 inches) deep
(Baker 1958, p. 98). This species has also been observed to use
secondary cavities, such as abandoned woodpecker holes, particularly in
dead pine trees (Strewe and Navarro 2004, p. 50). Military macaws
alternate nesting and foraging areas based on food availability
(Bonilla-Ruz 2006, p. 1). Nesting appears to be synchronous with the
peak fruiting season, which occurs during April and May (Huatatoca
pers. comm. in Arcos-Torres and Solano-Ugalde 2008, p. 70). The
military macaw is a social species that congregates in small flocks and
is often observed in mated pairs. Its clutch size is usually two to
three eggs. They begin reproducing between 3 and 4 years of age
(Mexican National Commission for Protected Areas [CONANP] 2006 in
Bonilla-Ruz 2006, p. 2). Colonial nesting is believed to be due to the
lack of suitable disbursed nest sites, which may also explain why they
are concentrated in certain sites (Salinas-Melgoza et al. 2009, p.
306).
This species prefers the lower montane wet forests of the Andes. It
inhabits remaining fragmented forested area in the Neotropics. However,
in the northernmost part of its range, in Mexico, it is associated with
seasonally dry, semi-deciduous tropical forest, deciduous tropical
forest, and slopes of pine-oak forest (Bonilla-Ruz et al. 2007b, pp.
45-47; Rivera-Ortiz et al. 2006, p. 26).
The military macaw is a seasonal migrant, based on food and
nutrient availability. In some areas, it has been observed at clay
licks to obtain sodium and possibly other minerals, which is a common
activity in some parrot species (Lee 2010, p. 58). Its diet varies
seasonally. Some of the plant species it was observed feeding on
include (Rivera-Ortiz et al. 2013, p. 1211; Carillo et al. 2013, p. 46;
Huellega 2011, p. 9; Moschione 2007, in Navarro et al., 2008, p. 2;

Seeds were found to be 39 percent of this species' diet. They have
also been observed feeding on bromeliad stems (species unknown) and
cacti (species unknown). In the northern part of its range in Mexico,
military macaws have been observed in desert habitat, although they
tend to have lower reproductive success in this habitat type (Rivera-
Ortiz et al. 2008, p. 261). In desert habitat, which is suboptimal, it
has been observed consuming some flowers (species unidentified).
Despite the low seasonal abundance of food, deserts offer some refuge
from poaching due to the inhospitable dry climate, which can act as a
deterrent to poachers (Rivera-Ortiz et al. 2008, p. 261). In addition,
macaws tend to nest at very high locations, which can make it difficult
for poachers to reach them.
Range, Observations, and Population Estimates
The military macaw is distributed in highly fragmented, small
populations in Mexico and South America, with a distribution gap in
Central America (BLI 2014a, pp. 1-2; Rivera-Ortiz 2013, p. 1,201;
Juarez et al 2012, pp. 6-7). Its range extends from northern Mexico
southward into Ecuador, Peru, Colombia, Venezuela, Bolivia, and the
southern tip of Argentina (see Figure 1 for an approximation of its
range and distribution). The species has been described as patchily
distributed throughout the eastern foothills of the Andes Mountains
(Snyder et al. 2000, p. 125). It occurs in altitudes up to 1,600 m
(5,249 ft) (Strewe and Navarro 2004, p. 50; Snyder et al. 2000, pp.
102, 124-125). Although it has a large distribution (276,000 km\2\
(106,564 mi\2\)), its populations are localized.
Its population is estimated to be 6,667-13,333 mature individuals
(BLI 2014, pp. 1-2; Rivera-Ortiz et al. 2013, p. 1,201). Most areas
where this species occurs are now estimated to have fewer than 100
individuals. However, in 2004, other populations in Colombia and Mexico
were estimated to be 100-200 individuals (Fl[oacute]rez and Sierra
2004, p. 3). This species may have occurred in Guatemala in the past,
but it is no longer found there (Gardner 1972 in Snyder et al. 2000, p.
125). Overall, its populations are fragmented and becoming more
isolated (Rivera-Ortiz 2008, p. 256).
[GRAPHIC] [TIFF OMITTED] TR02OC15.009
[[Page 59980]]
The species inhabits tropical, semi-deciduous forests along the
Pacific and Atlantic slopes through Central and South America. The best
available information indicates there are reasonably healthy but small
populations in El Cielo and Sierra Gorda Biosphere Reserves (Sierra
meaning mountain range) in Mexico, Madidi and Ambor[oacute] National
Parks, Pil[oacute]n Lajas Biosphere Reserve and Apolobamba National
Integrated Management Area in Bolivia, and Manu Biosphere Reserve and
Bahuaja Sonene National Park in Peru, and a small but stable remnant
population in Tehuacan-Cuicatlan Biosphere Reserve, Oaxaca, Mexico
(Lowry 2014, p. 3; Hosner et al. 2009, p. 222; Arizmendi 2008, p. 3;
Rivera-Ortiz 2008, p. 256). The population from Tehuacan-Cuicatlan
Biosphere Reserve, Oaxaca is about 100 macaws (Bonilla et al. 2007a, p.
731).
Argentina
Argentina is the southernmost part of this species' range, and the
species was never thought to have been abundant there (Navarro et al.
2008, p. 1). In fact, this species was initially thought to be
extirpated (locally extinct) in Argentina, but surveys have found small
populations in at least two locations in the northern province of Salta
(Grilli et al 2013, p. 235; Juarez et al 2012, pp. 7-8). There are
anecdotal reports of this species crossing the Ita[uacute] River
(Navarro et al. 2008, p. 3), which borders Bolivia and Argentina.
Between 2005 and 2007, approximately 100 individuals were observed in
the Salta Province. These areas include: Finca Itaguazuti, and the
Acambuco Provincial Flora and Fauna Reserve (8,266 hectares [ha] or
20,426 acres [ac]) in the Tartagal Mountains and which borders Bolivia
(BLI 2014; Navarro et al. 2008, pp. 1, 4; Coconier et al. 2007, p. 59).
In 2008, flocks of between 4 and 40 individuals of this species were
observed in three ravines in the Salta Province. These locations were
the Agua Fresca (Cool Water) Ravine north of Campo Cauzuti, El
Lim[oacute]n Ravine (which had the largest population), and the
Carapar[iacute] River Ravine. These are believed to be established
populations, rather than flocks crossing over from Bolivia (Navarro et
al. 2008, pp. 1, 4).
Bolivia
In Bolivia, the military macaw is regularly observed in five
national parks: Tambopata National Reserve, Pil[oacute]n Lajas
Biosphere Reserve, Madidi National Park, Apolobamba National Integrated
Management Area, and Ambor[oacute] National Park (Hennessey 2011, pers.
comm.). This species exists in the Andean foothills in Bolivia in
forested areas extending from the northern Tambopata National Reserve
to the southern Pil[oacute]n Lajas Reserve (Hennessey et al. 2003, pp.
319, 329). These parks are in the general vicinity of the border of
southern Peru and northern Bolivia (Hosner et al. 2009, p. 222; Navarro
et al. 2008, p. 2; Hennessey et al. 2003, p. 322). They are part of the
Greater Madidi-Tambopata Landscape (GMTL) (also known as ``Parque
Nacional Madidi''). Within the GMTL, there are thought to be reasonably
healthy populations of this species in the Apolobamba National
Integrated Management Area, Ambor[oacute] and Madidi National Parks,
and Pil[oacute]n Lajas Biosphere Reserve (Hennessey 2011 pers. comm.;
Hosner et al. 2009, p. 225). The Greater Madidi-Tambopata Landscape is
110,074 km\2\ (42,500 mi\2\) in size, and encompasses one of the
largest areas of intact montane forest in the tropical Andes (WCS 2009,
p. 2). This area is a high conservation priority due to its large
number of endemic bird species. Pil[oacute]n Lajas consists of primary
evergreen tropical lowland forest, foothill forest, and lower montane
forest. Pil[oacute]n Lajas was recognized as a Biosphere Reserve and
Indigenous Territory by the Bolivian Government in 1992; however, it
did not have any actual protections in place until 1994 (Hennessey et
al. 2003, p. 319).
In 2008, this species was observed at Serran[iacute]a Sadiri in
Madidi National Park, La Paz Department, Bolivia (Hosner et al. 2009,
p. 225). Serran[iacute]a Sadiri is found just inside Madidi National
Park. Here, flocks of between 2 and 36 individuals have been observed
(Hosner et al. 2009, p. 228). The Pil[oacute]n Lajas Biosphere Reserve
is primarily in La Paz Department, but slightly overlaps into the Beni
Department. Here, this species is described as uncommon (Hennessey
2003, p. 329). It was observed in Parapetiguasu-Taremakua, and
Parapetiguas-Uruwigua in Santa Cruz, Cordillera Province, and at
Altamachi and Madidi in Cochabamba, Ayopaya Province (MacLeod 2009, pp.
42-43). In summary, within Bolivia, there are many small populations of
this species in areas that provide suitable habitat for this species
(primarily large forest patches under some form of protection).
Colombia
In the late 1990s, there were approximately five disjunct
populations in the central Andes Mountains (Snyder et al. 2000, p.
125). In Colombia, groups of 50 individuals have been observed, and in
one case, a population was estimated to have 156 individuals
(Fl[oacute]rez and Sierra 2004, pp. 2-3). In most cases, these
individuals reside on cliff formations that are favorable for nesting
(where they are less accessible to poachers), and where deforestation
is having less of an impact (Fl[oacute]rez and Sierra 2004, pp. 2-3;
Rodriguez and Hern[aacute]ndez-Camacho 2002, p. 203). In Colombia, this
species inhabits a wide range of altitudes and areas with various
degrees of alteration (Fl[oacute]rez and Sierra 2004, pp. 1-3; Juniper
and Parr 1998). In Colombia, this species has been observed between
altitudes of 700 and 1,600 m (2,297 to 5,249 ft) (Fl[oacute]rez and
Sierra 2004, pp. 1-3; Salaman et al. 2002, pp. 167, 187). Populations
have been observed in Guajira peninsula, Las Orquideas, Tayrona
National Park, Serran[iacute]a de Perij[aacute], Serran[iacute]a de San
Lucas, San Salvador Valley, Sierra Nevada De Santa Marta, La Guajira
Department, and Cueva de los Guacharos National Park (Strewe and
Navarro 2003, p. 3). In 1998, this species was observed in flocks of up
to 12 individuals at Villa Iguana and Alto Cagadero in Serran[iacute]a
de los Churumbelos (Salaman et al. 2007, pp. 33, 38, 47, 89). It has
been observed in palm stands in the San Salvador valley during the
breeding season (December-July) (Strewe and Navarro 2003, p. 33).
There are two small, stable populations of military macaws at
Sierra Nevada de Santa Marta and Churumbelos, Cauca, with approximately
50 mature birds at each site (Fundaci[oacute]n ProAves 2011, p. 28). In
2004, Fl[oacute]rez and Sierra estimated that the population in the
cliffs of the Cauca River was 156 individuals and contained 54 breeding
pairs and 26 nests (2004, p. 3). However, this population is subjected
to impacts from poaching and deforestation (Fl[oacute]rez and Sierra,
2004, pp. 3-4), so the population now may be smaller. These researchers
also noted that many chicks fall from the cliff nests and die. As of
2011, there were no recent records in northern Antioquia (Paramillo),
Serran[iacute]a de San Lucas, or Perij[aacute] ranges (Fundaci[oacute]n
ProAves 2011, pp. 28-29).
In the Fr[iacute]o Valley of Colombia, this species is reported to
be present only during the breeding season (Strewe and Navarro 2004, p.
50). Several nests were found here in forest fragments. A population at
El Congo Reserve was intensively studied in 2001. One nest was located
12 m (39 ft) above ground in a Ceiba tree, within open primary forest
on a steep slope at 900 m (2,953 ft). A breeding population of 12
pairs, with groups of up to 28 was observed in December 2000. However,
here it is still threatened in the valley by habitat loss and domestic
trade (two cases noted in 2001) (Strewe and Navarro
[[Page 59981]]
2004, p. 50), and the population may now be decimated.
Ecuador
In Ecuador, this species is considered to be very rare (Arcos-
Torres and Solano-Ugalde 2008, p. 71). This species has been observed
in the areas of Sumaco and Zamora-Chinchipe in Ecuador (Snyder et al.
2000, p. 125) and at Kichwa River Reserve (Reserva Kichwa R[iacute]o),
within the Gran Sumaco Guacamayos Biosphere Reserve (Arcos-Torres and
Solano-Ugalde 2008, p. 72). Most records of military macaw in Ecuador
during the 1980s and 1990s found groups of up to 20 individuals
(Ridgely and Greenfield 2001); however, lately most records have not
exceeded 8 individuals (Arcos-Torres and Solano-Ugalde 2008, p. 71)
except for a breeding colony of 16 individuals that was observed in the
Reserva Kichwa R[iacute]o (Arcos-Torres and Solano-Ugalde 2008, pp. 70-
72). Prior to 1980, it was observed in the upper Upano River Valley
(Ridgely 1980 p. 244). In 2006, 200 ha (494 ac) were turned into the
Narupa Reserve, where this species was observed in approximately 2010
(Fundaci[oacute]n ProAves et al. 2010, p. 42). Additionally, in 2010, a
pair of military macaws was observed in northern Ecuador in the Sumaco
region (Olah and Barnes 2010, p. 19).
Mexico
There are several small populations of military macaws in Mexico,
each consisting of between approximately 20 and 90 individuals
(Jimenez-Arcos et al. 2012, p. 864; Rivera-Ortiz et al. 2008, p. 256),
although there has been an anecdotal report of a population estimated
to be 130 individuals (Bonilla 2012, p. 6). This species follows
seasonal food sources, so flocks move to other areas seasonally. In
Mexico, there are reasonably healthy but small populations in the
following areas:
Alamos Rio Cuchujaqui (Sonora),
Puerto Vallarta (Jalisco),
Tehuacan-Cuicatlan Biosphere Reserve (at the border of Puebla
and Oaxaca States) Mineral de Nuestra Se[ntilde]ora Reserve (Sinaloa),
El Cielo Biosphere Reserve (Tamaulipas),
Sierra Gorda Biosphere Reserve (Quer[eacute]taro),
Sierra Manantl[aacute]n Biosphere Reserve (Jalisco),
Vicinity of Copalillo (Guerrero) (Jimenez-Arcos et al. 2012,
p. 865).
[GRAPHIC] [TIFF OMITTED] TR02OC15.010
In Mexico, there may also be isolated populations of military
macaws in other States. Figure 2 shows the approximate present day and
historical distribution of the military macaw in Mexico as of 2008
(Arizmendi 2008, p. 4). Other States where it may exist include Colima,
Durango, Michoac[aacute]n, Morelos, Nayarit (in the Valley of Flags or
``Valle de Banderas''), Nuevo Le[oacute]n, San Luis Potos[iacute], and
Zacatecas. Areas where it has been recently documented are described
below.
Chihuahua
Researchers believe there is a remaining population in the Sierra
Madre Occidental Mountains (north-central Mexico) in Otachique (Cruz-
Nieto et al. 2006, p. 14). In 2005, 25 nests were observed (Cruz-Nieto
et al. 2006, p. 14). This canyon is approximately 700 m (0.5 miles)
wide by 14 km (8.6 miles) in length and consists of mature pines, firs,
and oaks. Some gallery temperate forest remains in this area.
[[Page 59982]]
Guerrero
A colony of approximately 20 military macaws was studied between
2006 and 2010 in the vicinity of Copalillo, Guerrero (Jim[eacute]nez-
Arcos et al. 2012, pp. 864-865). The vegetation is tropical deciduous
forest; and a canyon is present.
Jalisco
This species is found sporadically in small groups of a few to
approximately 100 macaws in the western foothills of Sierra del Cuale
and Sierra Cacoma in Jalisco on the western coast of Mexico (Renton
2004, pp. 13-14). Other groups of macaws in the region are in Cabo
Corrientes in the Horcones river basin (approximately 100 macaws).
There are other small populations in the vicinity of Puerto Vallarta
(Carrillo et al. 2013, pp. 45, 47). This species was observed in 2004
near a freshwater lake, Caj[oacute]n de Pe[ntilde]a (26 by 9 km (16 by
5.6 mi) in size), which was constructed in 1976. It is found in the
Chamela-Cuixmala Biosphere Reserve (132,000 ha or 32,617 ac), which is
managed by Mexico's Instituto de Ecologia of the National Autonomous
University of Mexico (UNAM) and nongovernmental organizations (NGOs).
Patches of semi-deciduous forest in this area form corridors between
existing protected areas, such as the Chamela-Cuixmala and the Sierra
Manatl[aacute]n Biosphere Reserves (Renton 2004, p. 14). These patches
likely have served as critical ecological links for this species.
Oaxaca
This species has recently been the focus of research in Sabino
Canyon, Oaxaca. Sabino Canyon is in the Tehuacan-Cuicatlan Biosphere
Reserve (Reserva de la Biosfera Tehuacan Cuicatlan), created in 1998,
in central Mexico. The reserve spans 490,187 ha (1,211,278 ac) and is
located within the Mixteca Oaxaque[ntilde]a Province between the cities
of Puebla and Or[iacute]zaba. It is approximately 150 km (93 mi)
southeast of Mexico City (https://www.parkswatch.org, accessed July 11,
2011) and approximately 2 hours from Tehuacan, Oaxaca, Mexico. Large
mountain ranges delineate the boundaries of the reserve, and six rivers
are within the protected area's boundaries.
In 2001, this species was observed in two canyons within this
reserve. In both ravines, 20 pairs were observed nesting (Salazar-
Torres 2001, p. 18). Here, this species nests in the canyon cliff walls
in crevices that can be as high as 250 m (820 ft). Between 2002 and
2004, approximately 100 individual military macaws were observed
(Bonilla-Ruz et al. 2007a, p. 729). During 2007-2008, at least 67 birds
were observed during the month of August (Rivera-Ortiz et al. 2008, p.
256; Rivera-Ortiz et al. 2006, p. 26). The known nesting site locations
within the reserve increased from five to nine during the study period
(Rivera-Ortiz et al. 2006, p. 28). Currently in the Sabino Canyon, the
population of military macaws is thought to be between 90 and 100
individuals (Arizmendi 2008, p. 15).
Sinaloa
This species exists in Mineral de Nuestra Se[ntilde]ora de la
Candelaria Ecological Preserve, 12 km (7.4 mi) southeast of the town of
Cosala in Sinaloa, Mexico (Rubio et al. 2007, p. 52; Bonilla-Ruz et al.
2007b, p. 45). The preserve is 1,256 ha (3,104 ac) and consists of dry
tropical forest. In 2002, this area was designated as a protected area
by the State of Sinaloa Decree.
Sonora
Between 2008 and 2009, it was observed at the Northern Jaguar
Reserve in east-central Sonora, and was described as a rare summer
resident there (Flesch 2009, pp. 5, 12). In this area, this species was
recently observed in small flocks in cliff areas (Flesch 2008, pp. 35-
36). In 2005, it was observed in the R[iacute]o Aros canyon and upper
R[iacute]o Yaqui valley in an area known as the Yaqui Basin (O'Brien et
al. 2006, pp. 4, 27-28). Flesch suggests that the species is likely to
occur only in cliffs near stands of tropical vegetation (full citation
2008, p. 27).
Tamaulipas
Historically, in Mexico's eastern State of Tamaulipas, flocks of
approximately 60 individuals were noted almost daily in the area of
G[oacute]mez Far[iacute]as, Mexico (Sutton and Pettingill 1942, p. 14).
The G[oacute]mez Far[iacute]as region is on the eastern slope of the
Sierra Madre Oriental mountain range, known locally as the ``Sierra de
Guatemala.'' This area is in the general vicinity of the state-
protected El Cielo Biosphere Reserve, where this species is still known
to occur (Arvin 2001, p. 8). The University of Texas at Brownsville
maintains a research station, Rancho del Cielo, within the 145,687-
hectare (360,000-acre) reserve. The research station supports locally
driven scientific research and community development (University of
Texas at Brownsville, unpaginated). Activities conducted by the
research station have positive impacts on this species by attracting
researchers and the birding community, preserving and protecting
habitat, and creating awareness in the area.
Peru
There are populations in Manu Biosphere Reserve, Tambopata National
Reserve, and Bahuaja Sonene National Park in Peru. The two latter parks
border one another in the southern Peruvian Amazon region (ParksWatch
2002, p. 1). This species has been observed around the Pongo de
Mainique of the Urubamba River and on the upper Tambopata River (Snyder
et al. 2000, p. 125). According to a 2010 paper, it was observed in the
Madre de Dios department in the southeastern Peruvian Amazon (Lee 2010,
p. 14). Flocks of 40 to 50 individuals have been observed in Atalya at
Madre de Dios (Snyder et al. 2000, p. 125). The species has been
observed seasonally in small numbers in the area of the Hu[aacute]llaga
River Canyon (JGP Consultants 2011 pp. 1, 5, 8).
Venezuela
Within Venezuela, it has been documented primarily within protected
areas. In this country, little information about the species exists
(Rodriguez et al. 2004, pp. 375-376). Here it persists in the Andes in
the Central Coastal Cordillera and Sierra de Perij[aacute] (Rodriguez
et al. 2004, pp. 375, 378, 379). It has been found on the north slopes
of El [Aacute]vila, Guatopo, Henri Pittier National Park, the State of
Cojedes, Cerro La Misi[oacute]n, and Sierra de Perij[aacute] National
Park (Desenne and Strahl 1994 and Fernandez-Badillo et al. 1994 in
Snyder et al. 2000, p. 125). A new population of this species was
recorded at two localities at the Catatumbo-Bar[iacute] National Park
along the Colombian-Venezuelan border (Avenda[ntilde]o 2011, p. 2).
Moist forests exist as four distinct enclaves within the Catatumbo
Valley, in both northwestern Venezuela and northeastern Colombia. This
extends the species' previously known range from the east slope of the
Serran[iacute]a de Perij[aacute] southwards (Avenda[ntilde]o 2011, p.
2).
Summary of Range
According to several surveys, the military macaw exists in small
populations ranging from a few pairs to approximately 100 individuals.
It is found in protected areas in Mexico, Colombia, Bolivia, and to a
lesser extent, in Ecuador, Peru, Venezuela, and Argentina (see Figure
1), and is unlikely to exist in small populations outside of protected
areas where large expanses of suitable habitat still remain (Bonilla
2012, p. 9). The population in the Pil[oacute]n Lajas Biosphere
Reserve, Bolivia, may
[[Page 59983]]
serve as a link to other populations of this species to the northwest
and to the south (Hennessey et al. 2003, pp. 330-331). Records indicate
that this species occurs primarily in protected areas (Flesch 2009;
MacLeod 2009; Flesch 2008; Fl[oacute]rez and Sierra 2004; Rodriguez
2004; Renton 2004; Hennessey et al. 2003), such as protected parks
where there are large remaining areas of suitable habitat for nesting,
feeding, and breeding (see Figure 1).
Summary of Population Estimate
There are various but imprecise population estimates for the
military macaw. One report estimates the population to be fewer than
10,000 individuals (Arizmendi 2008, p. 3). BLI reports that the
population is estimated to be between 10,000 and 19,999 mature
individuals with a decreasing trend (BLI 2014, p. 2). We believe that
the population is significantly fewer than 10,000 based on recent
documented observations of this species, most of which are described in
this status review. Researchers in Colombia agree with our conclusion
(Botero-Delgadillo and P[aacute]ez 2011, p. 13). Published literature
(referenced in this document) has documented small flocks ranging from
approximately 16 to 156 individuals distributed in disjunct locations
in Mexico, Argentina, Ecuador, Venezuela, Peru, Colombia, and Bolivia.
In situations where the species is rare or has small populations, the
number of observations made per survey may be very small and the number
of sites limited, and, therefore, estimates may not be accurate
(Pollack 2006, p. 891).
The current total population number is unclear; however, based on
these recent records, we believe that the population is between a few
thousand and 10,000 remaining individuals (BLI 2014, p. 1; Bonilla
2012, p. 9).
Conservation Status
International Union for Conservation of Nature (IUCN)
There are various protections in place for this species at the
international, national, and local levels. At the international level,
this species is listed as vulnerable by the IUCN (2011). However, this
status under IUCN conveys no actual protections to the species.
CITES
The military macaw is protected by the Convention on International
Trade in Endangered Species of Wild Fauna and Flora (CITES), which is
one of the most important means of controlling international trade in
animal and plant species affected by trade. CITES is an international
agreement through which member countries, called Parties, work together
to ensure that international trade in CITES-listed animals and plants
is not detrimental to the survival of wild populations by regulating
their import, export, and reexport. All of the range countries for this
species are Parties to CITES (https://www.cites.org/eng/disc/parties/alphabet.php, accessed May 7, 2014). Most psittacines (parrots),
including the military macaw, were included in CITES Appendix II in
1981. An Appendix-II listing includes species not necessarily
threatened with extinction, but in which trade must be controlled in
order to avoid utilization incompatible with their survival. The
military macaw was transferred to Appendix I of CITES in 1987, because
populations were declining rapidly due to uncontrolled trapping for the
international pet bird trade. An Appendix-I listing includes species
threatened with extinction whose trade is permitted only under
exceptional circumstances, which generally precludes commercial trade.
WBCA
The import of the military macaw into the United States is also
regulated by the Wild Bird Conservation Act (WBCA) (16 U.S.C. 4901 et
seq.), which was enacted on October 23, 1992, in an effort to ensure
that exotic bird species are not adversely affected by U.S. trade. The
purpose of the WBCA is to promote the conservation of CITES-listed
exotic birds by ensuring that all imports into the United States are
(1) sustainable and (2) not detrimental to the species. Permits may be
issued to allow imports of listed birds for scientific research,
zoological breeding or display, or as personal pets when certain
criteria are met. The Service may approve cooperative breeding programs
and subsequently issue import permits under such programs. Wild-caught
birds may be imported into the United States if the Service approves a
management plan for their sustainable use. At this time, the military
macaw is not part of a Service-approved cooperative breeding program
and does not have an approved management plan for wild-caught birds.
Argentina
This species is considered to be a critically endangered species by
the Government of Argentina (Navarro et al. 2008, p. 1). It is
protected through national legislation (Law 22.421 and Decree 691/81),
administered by the Direcci[oacute]n Nacional de Fauna y Flora
Silvestres. Law 22.421 addresses the Conservation of Fauna, enacted in
1981. Decree 691/81 addresses the protection and conservation of wild
fauna and is implemented through law 22.421.
Bolivia
In Bolivia, this species is listed as vulnerable. The 1975 Law on
Wildlife, National Parks, Hunting and Fishing (Decree Law No. 12,301
1975, pp. 1-34) has the fundamental objective of protecting the
country's natural resources. This law governs the protection,
management, utilization, transportation, and selling of wildlife and
their products. It also governs the protection of endangered species,
habitat conservation of fauna and flora, and the declaration of
national parks, biological reserves, refuges, and wildlife sanctuaries.
Colombia
Colombia categorizes this species as ``vulnerable'' (Salaman et al.
2009, p. 21). A vulnerable species is considered to be one that is not
in imminent danger of extinction in the near future, but it could be if
natural population trends continue downward and deterioration of its
range continues (EcoLex 2002, p. 10).
Ecuador
In Ecuador, this species is considered endangered, ``en peligro de
extinci[oacute]n''. Here, this species is considered to be very rare
(Arcos-Torres and Solano-Ugalde 2008, p. 69).
Mexico
In Mexico, the military macaw is protected as endangered under
Mexico's Wildlife Protection Act (Benetiz-Diaz 2012, p. 2) and has been
highlighted as a priority species for conservation in the Mexican
Parrot Conservation Plan (Rivera-Ortiz et al. 2008, p. 256; Renton
2004, p. 12). Its official list of endangered and threatened bird
species is termed the Norma Oficial Mexicana 059 (NOM-059, 2010)
(Benetiz-Diaz 2012, p. 2).
Peru
In Peru, this species is listed as vulnerable and its protections
fall under the jurisdiction of the National Institute of Natural
Resources (Instituto Nacional de Recursos Naturales, INRENA). Peru's
Supreme Decree No. 034-2004-AG (2004, p. 276,855) prohibits hunting,
take, transport, and trade of protected species, except as permitted by
regulation.
Venezuela
In Venezuela, this species is listed as endangered (Rodriguez et
al. 2004, p. 376).
[[Page 59984]]
NGO Involvement
In the 1980s, conservationists realized the value of identifying
areas or habitat in terms of numbers of endemic bird species. BirdLife
International, in partnership with countries, other nongovernmental
organizations (NGOs), and various other partners, developed the
Important Bird Area (IBA) program, which is a worldwide initiative to
identify and protect critical areas for bird conservation. IBAs are
areas that regularly contain significant numbers of one or more
globally threatened species or other species of global conservation
concern. One of the criteria in identifying important regions for bird
conservation is the distribution of restricted-range and globally
threatened species such as the military macaw. As of 2007, more than
8,500 IBAs had been identified worldwide (Garc[iacute]a-Moreno et al.
2007, p. 324). The military macaw is included in 37 of those IBAs (BLI
2011b, pers. comm.). Note that this does not mean this species always
occupies those areas; rather, the species has been identified in those
areas.
A number of locally based and international conservation
organizations have developed programs in connection with protected
areas within this species' range, such as ecotourism, to observe clay
lick areas (Lee 2010, pp. 167-168). The Wildlife Conservation Society
(WCS) is implementing a range of projects aimed at strengthening the
management of Greater Madidi-Tambopata Landscape in Bolivia. Its
program is based on three main categories: (1) Park management, (2)
natural resources management, and (3) scientific research (Parks Watch
2005, pp. 2-3). The Greater Madidi-Tambopata Landscape, where the WCS
is monitoring populations of the military macaw (WCS 2009, pp. 2, 8),
encompasses one of the largest swaths of intact montane forest in the
Tropical Andes in northern Bolivia and southern Peru. The GMTL is
110,074 km\2\ (42,500 mi\2\) and includes five protected areas.
A Colombian-based NGO, Fundaci[oacute]n ProAves, is also working to
protect this species and its habitats. Fundaci[oacute]n ProAves
developed a conservation plan for 2010 to 2020 for several parrot
species, including the military macaw (Botero-Delgadillo and
P[aacute]ez 2011, p. 7). However, it is unclear if or when it will be
adopted by the Government of Colombia.
In Mexico, several NGOs are participating in the conservation and
management of this species. In 1989, a strong citizen movement began to
conserve the 383,567-ha (947,815-ac) Sierra Gorda Biosphere Reserve by
establishing the local group, Grupo Ecol[oacute]gico Sierra Gorda. In
collaboration with the local community, this group has taken action to
protect bird communities as well as other groups of wildlife in this
area. Strategies include environmental education, establishment of
private reserves, and payment for environmental services in a 25,000-ha
(61,776-ac) area of this reserve (Pedraza-Ruiz, 2008 p. 1). The
Chamela-Cuixmala Biosphere Reserve is managed by Mexico's Instituto de
Ecologia of the National Autonomous University of Mexico (UNAM) and
local NGOs. Other NGOs are working with communities to obtain macaw
feathers from aviaries so that indigenous people will not hunt the
macaws for their feathers (Renton 2004, p. 14). In the Sinaloa area,
the Universidad Aut[oacute]noma de Sinaloa has been active in
conservation of this species since 1998 (Rubio et al. 2007, p. 52).
This university conducts research outreach activities to foster
knowledge, and conservation of this species at the Mineral de Nuestra
Se[ntilde]ora de la Candelaria Ecological Preserve.
Evaluation of Threat Factors
Introduction
Section 4 of the ESA (16 U.S.C. 1533) and implementing regulations
(50 CFR 424) set forth procedures for adding species to, removing
species from, or reclassifying species on the Federal Lists of
Endangered and Threatened Wildlife and Plants. Under section 4(a)(1) of
the ESA, a species may be determined to be endangered or threatened
based on any of the following five factors:
A. The present or threatened destruction, modification, or curtailment
of its habitat or range;
B. Overutilization for commercial, recreational, scientific, or
educational purposes;
C. Disease or predation;
D. The inadequacy of existing regulatory mechanisms; and
E. Other natural or manmade factors affecting its continued existence.
Throughout the range of this species, the factors impacting this
species are generally very similar. The primary factors affecting the
military macaw are habitat loss and degradation, and poaching (Carrillo
et al. 2013, p. 46; Gasta[ntilde]aga et al. 2011, entire; Strewe and
Navarro 2004, p. 50). Habitat loss is primarily due to conversion of
the species' habitat (generally forests) to agriculture and other forms
that are not optimal for the military macaw (Donald et al. 2010, p. 26;
Fl[oacute]rez and Sierra 2004, p. 3). Conversion of habitat to soy
plantations is now considered to be one of the principal causes of
Amazon deforestation (Bonilha 2008, p. 17). Because this species has a
small and fragmented population, poaching, while apparently uncommon,
remains a concern (Botero-Delgadillo and P[aacute]ez 2011, p. 13).
We focus primarily on where this species has been documented,
particularly in parks and other areas with protected status and the
peripheral zones. In some cases, we will evaluate the factor by
country. In other cases, we may evaluate the factor by a broader region
if we do not have adequate information specific to a particular country
about this species. This is because often the threats are the same or
very similar throughout the species' range.
A. The Present or Threatened Destruction, Modification, or Curtailment
of Its Habitat or Range
Habitat
The military macaw has a large but fragmented distribution (276,000
km\2\ (106,564 mi\2\)), and not all locations where the military macaw
exists are known (BLI 2014, p. 1). Habitat destruction and modification
is one of the main threats to the military macaw; significant amounts
of this species' habitat have been converted such that its habitat is
no longer suitable and no longer provides adequate shelter (nesting
sites) and food sources, and these causes of habitat loss are likely to
continue (Marin-Togo et al. 2012, p. 462). Between 2000 and 2005, of
all the continents, South America had the largest net loss of forested
area, experiencing a loss of 4.3 million ha (10.6 million ac) per year
(FAO 2006 in Mosandl et al. 2008, p. 38). In some countries, extractive
activities for nontimber forest products occur, such as the removal of
palm trees (Arecaceae family) to obtain hearts of palm (ParksWatch
2011; https://www.tropicalforestresearch.org).
Currently, the military macaw exists in many parks and other areas
that have protected status (Mar[iacute]n-Togo et al. 2012, p. 465;
Coconier et al. 2009, p. 63; Arizmendi 2008, p. 4; Rodriguez et al.
2004, p. 78; Renton 2004, p. 12). Studies have found that, compared
with the surrounding areas, conditions inside parks were significantly
better than their surrounding counterparts (Bruner et al. 2001, p.
125). One study found that, in 40 percent of tropical parks, land that
had formerly been under cultivation and that was incorporated into park
boundaries had recovered. This subsequently led to an increase in
vegetative cover. The study found that
[[Page 59985]]
83 percent of parks were successful at mitigating encroachment (Bruner
et al. 2001, p. 125). This was confirmed in a study published in 2007
that found that forests in conservation units were four times better at
protecting against deforestation than unprotected areas (Oliveira et
al. 2007, p. 1,235). However, this species still faces habitat loss
(Benetiz 2012, p. 4).
We are limiting our analysis to areas where there is information
available about this species. For instance, there is very little
information available about this species in Argentina and Venezuela
(Coconier et al. 2009, p. 63; Navarro et al. 2008, p. 1; Coconier et
al. 2007, p. 52; Rodriguez et al. 2004, pp. 378-379). However, in both
of these countries, the species faces similar threats (such as the lack
of suitable habitat) as in other countries (Rodriguez et al. 2004, p.
373). The largest populations of this species, discussed in detail in
the Range, Observations, and Population Estimates section, appear to be
in Mexico and Bolivia. Even in these countries, its populations are
small and fragmented. In other countries within its range such as
Colombia, Peru, and Ecuador, it exists in smaller populations, and
Argentina (Nores and Yzurieta 1994, pp. 315-316) and Venezuela have
even smaller and possibly negligible populations. Additionally, the
military macaw may have occurred in Guatemala in the past, but it is no
longer found there (Gardner 1972 in Snyder et al. 2000, p. 125).
Argentina
In Argentina, habitat destruction, particularly deforestation for
agricultural expansion for soy plantations, and timber extraction had
significantly increased as of 2009 (Devenish 2009, p. 60; Chebez et al.
in litt. in Navarro et al. 2008, pp. 7, 9; DiPaola et al. 2008, pp. 1,
8). The species was thought to no longer exist in Argentina, which is
the southernmost part of its range, but recent surveys found small
populations of this species in at least two locations in the Salta
Province (Navarro et al. 2008, p. 1). The primary threat to forested
areas in Argentina is the expansion of agriculture, particularly soy,
into remaining habitat such as the Chaco plains in the Andes mountain
range (Centro de Acci[oacute]n Popular Olga M[aacute]rqu[eacute]z de
Aredez (CAPOMA) 2009, p. 6). The practice of drying swamps through
channeling is common in northern Argentina, particularly for producing
soybeans, which is experiencing increasing demand in the global market.
The current rate of deforestation stands at 25,000 ha (61,776 ac) per
year resulting from land converted to agricultural use (Devenish 2009,
p. 60). The area converted to soy production increased from as little
as 3 percent in the 1970s to 40 percent of the total crop area in 2003,
covering 14 million ha (34.6 million ac) (Devenish 2009, p. 60).
Conversion of lands to soy production is favored by the current
political and economic climate, both at the global and national levels
(Devenish 2009, p. 60). With regard to other types of land use, the
area used for cattle ranching has decreased, but exotic tree
plantations have doubled (Devenish 2009, p. 60).
In addition, pipeline routes and associated roads are being
established in this area in connection with oil, gas, and mineral
exploration (Navarro et al. 2008, pp. 7, 9). Road building operations
greatly facilitate access to large, previously inaccessible forested
areas (Fimbel et al. 2001, pp. 511-512). The area occupied by permanent
facilities including pipelines and refineries is relatively small, but
oil development areas cover large tracts of land. Oil development can
have significant negative impacts on nearby habitat through
construction of roads and other buildings, discharge of contaminants,
and oil spills and leaks (Gay et al undated, pp. 2-6).
Although some of this species' habitat is protected, its habitat
continues to shrink in Argentina. In the area of Acambuco, where the
military macaw has been observed, the designation of Acambuco Reserve
as a provincial reserve provides some protective measures. The purposes
of this reserve, in part, are to preserve its genetic resources, to
preserve the environment surrounding catch basins of its rivers, and to
guarantee the maintenance of the biodiversity living in the reserve.
However, in the Salta Province, this species is primarily found in
areas that are unprotected, with the exception of the Acambuco Reserve
(Navarro et al. 2008, pp. 1, 7, 9). In summary, significant amounts of
this species' habitat have been converted such that its habitat is no
longer suitable, and these causes of habitat loss are likely to
continue.
Bolivia
Madidi National Park experiences threats that are representative of
threats to this species' habitat in Bolivia. The park is one of the key
areas where this species likely has a viable population in Bolivia.
Thus, we focused our analysis on this park. The National Service of
Protected Areas (SERNAP) has authority over Bolivia's parks and
protected lands. Approximately 53 percent (57.2 million ha; 141.3
million ac) of Bolivia's total area is forested (FAO 2010, p. 228). Of
this area, 38.9 million ha (96.1 million ac) are within the Bolivian
Amazon and constitute 5 percent of the total Amazon forest (Locklin and
Haack 2003, p. 774). As of 2005, Bolivia had 12 national parks,
including 6 with integrated management natural areas, 1 with indigenous
territory (or communal lands), and 4 national reserves; 2 biosphere
reserves; and 3 integrated management natural areas, totaling
16,834,380 ha (41,598,659 ac) (ParksWatch 2005, p. 2). A discussion of
typical threats in Bolivia's parks follows. The region suffers from
chronic and intense poverty levels, which affect more than 90 percent
of the population (Instituto Nacional de Estad[iacute]stica de Bolivia
(INE) 2005). The result is intense conflict between development and
conservation. In Madidi National Park, the three greatest threats to
the nature preserve are the construction of a highway within the park,
drilling for oil, and a planned hydroelectric dam. Other activities
that are impacting or are likely to impact this park are illegal
logging, gold mining, and uncontrolled tourism (ParksWatch 2011b, pp.
1-15; Chavez 2010, pp. 1-2).
Deforestation and Logging
The forests of Bolivia have mainly been subjected to selective
logging (Salo and Toivonen 2009, p. 610; Fredericksen 2003, p. 10),
which has been done at very low levels and with low human pressures
(Pacheco 2006, p. 206), allowing them so far to remain largely intact.
In the five national parks where the military macaw is regularly
observed, there are some protections in place for the species' habitat
(Hennessey 2011, pers. comm.). However, logging still occurs within the
range of this species (ParksWatch 2011b, p. 1). Large tracts of primary
forest remain in Bolivia, but it is likely that some of these will be
subjected to logging (Fredericksen 2003, p. 13) due to slash-and-burn
activities by indigenous communities, and because forest products are
one of Bolivia's primary exports (Byers and Israel 2008, p. vi). The
use of slash-and-burn practices on steep and erodible slopes has
considerably affected the area's hydrological regime, particularly near
the city of Santa Cruz. In many areas of human settlement, soil erosion
is compounded by logging, nutrient depletion, and weed invasion.
As of 2006, 89 timber companies held the rights to 5.8 million ha
(14.3 million ac) of logging concessions (Pacheco 2006, p. 208). The
Bolivian Forestry Law of 1996 (Forestry Law 1700)
[[Page 59986]]
requires the preparation and approval of management plans and adherence
to best management practices (BMPs) (Fredericksen 2003, p. 10). For
instance, harvesters must pre-map harvestable trees (which have minimum
diameter limits), protect seed trees, and set aside areas that are
designated as protected or not harvestable. Management issues still
need to be addressed, including sufficient regeneration time for
commercial species (Fredericksen 2003, p. 10). However, Bolivia
continues to attempt to balance the use of its natural resources with
competing priorities. For example, the Pil[oacute]n Lajas Management
Plan divided the reserve into specific zones to combine indigenous
community rights with conservation initiatives (Hennessey et al. 2003,
p. 320). Despite national laws and regulations, activities such as
illegal timber extraction continue to spread unabated (World Bank 2006,
p. 8; U.S. Forest Service 2007, p. 2; Pacheco 2006, p. 208).
Roads
There are increasing demands for road infrastructure within Bolivia
for many reasons. It is one of the poorest countries in South America
(MacLeod 2009, p. 6; INE 2005), and the government would like to
improve its economy (ParksWatch 2011b, p. 13). The construction of the
Apolo-Ixiamas Road is one way of facilitating access to its natural
resources. A road has been proposed that would bisect the Madidi
National Park and Natural Integrated Management Area, opening vast,
currently inaccessible tropical forest areas to colonization and
resource extraction (ParksWatch 2011b, pp. 1-2). This can promote
illegal logging, and facilitate access to previously inaccessible
forested areas (Fimbel et al. 2001, pp. 511-512). The construction of
roads through this park has been a source of controversy for several
years https://conservation-strategy.org/sites/default/files/field-file/6_Madidi_Road_Complete_Document.PDF, accessed May 6, 2014). The current
status of the road and whether it will be constructed around the park
or through the park remains unclear. However, regional development
plans are often implemented without consideration of impacts on natural
resources (WCS 2009, p. 4). Plans to connect Bolivia and Peru to
Brazil's expanding markets and expand the energy industry (oil and gas)
will affect fragile areas of high biodiversity (WCS 2009, p. 4). Roads
constructed in the past have also been problematic. In the late 1990s,
roads through Serran[iacute]a Sadiri spurred an increase in
unsustainable logging of the area's mahogany trees, which were the most
valuable tree at the time (World Land Trust 2010, p. 1).
Hydroelectric Power
Possibly one of the greatest threats in the Madidi National Park is
the proposed Bala Hydroelectric Dam Project at the Beni River in the
Bala Gorge, where the Beni River goes through the Bala Mountain Range.
The Bala Hydroelectric Dam, as proposed, could flood much of Madidi
National Park and the adjacent biosphere reserve and indigenous
territory Pil[oacute]n Lajas, which is an area of about 2,000 km\2\
(4,942 mi\2\) (Chavez 2010, pp. 1-2; Bolivia Supreme Decree 24191).
Construction of dams can have severe impacts on ecosystems (McCartney
et al. 2001, p. v). For example, a dam blocks the flow of sediment
downstream. During construction of dams, disturbance to soils at the
construction site is one of the largest concerns. This leads to
downstream erosion and increased sediment buildup in a reservoir.
Although the current status of this dam is unclear, it is clear that
the Government of Bolivia is intent on becoming more self-reliant, in
part through creating its own sources of energy through hydroelectric
dams.
Other Pressures
In Madidi National Park, there is limited legal hunting, but in the
areas surveyed, this species was described as common and not exploited
(Hosner et al. 2009, p. 226). Nine villages or communities are within
the national park, and 22 are in the integrated management natural
area. Of the 31 communities, 3 are located in the Andean plateau zone.
In the lowlands, two of the communities occupy the zone of valleys
around the municipality of Apolo. Timber extraction occurs here
(WorldLand Trust 2010, p. 1). In 2010, an additional 25,090 ha (62,000
ac) of pristine tropical rainforest in Bolivia were protected,
following a decision by an indigenous community to create a tourism
refuge in the Sadiri rainforest (WorldLand Trust 2010, p. 6). Landless
Andean farmers make a living in the lowlands, and they at times expand
the agricultural frontier, increasing the risk of disease transmission
between domestic animals and wildlife, bringing crops and domestic
animals closer to wildlife predators, and increasing hunting pressure
in surrounding forests (WCS 2009, p. 4).
In summary, threats to the species' habitat in Bolivia include
unsustainable land use practices, illegal logging, road building, and
exploration activities for oil extraction, which are contributing to
the erosion of Bolivia's ecosystems (MacLeod 2009, p. 6; ParksWatch
2005, p. 1). Large tracts of primary forest remain in Bolivia, but it
is likely that many of these will be subjected to logging and other
pressures, such as extraction of non-timber forest products,
particularly because forest products contribute to Bolivia's national
exports (Byers and Israel 2008, p. vi). The Government of Bolivia is
attempting to balance improving its economy with conservation
initiatives, and some of its development initiatives may negatively
impact this species' habitat. Despite protections in place, this
species' habitat in Bolivia continues to experience these threats, and
we expect these pressures to continue into the future.
Colombia
In the past, human colonization, development, and exploration
within the range of the species in Colombia were limited due to the
exceptionally steep and high terrain of the Andes (Salaman et al. 2002,
p. 160). However, researchers reported in 2004 that the Cauca River
Canyon in northeastern Colombia, an area containing military macaws,
was extensively deforested (Flor[eacute]z and Sierra 2004, p. 3). The
main threats in the lowlands are the expansion of agriculture,
particularly by small farmers in the middle altitude areas, and
extractive activities such as hunting (including the removal of birds
to sell as pets) and wood harvesting (Salaman et al. 2007, p. 89). As
resources become scarcer in the lowlands, these pressures move upland.
Associated with these farming practices is the use of livestock and the
erosion caused by livestock grazing on steep slopes, as well as erosion
due to cultivation.
A 2010 report indicated that forest cover was largely continuous in
Colombia, but deforestation had increased dramatically as of 2010 (FAO
2010, pp. 22, 106). Deforestation rates in lowland moist forest on the
foothills of the eastern Andes of Colombia are rapidly accelerating.
Deforestation has increased from 1.4 percent (1961-1979) to 4.4 percent
(1979-1988), and is correlated with increasing human population density
(Salaman et al. 2007, p. 89; Vi[ntilde]a and Cavelier 1999, p. 31).
Primary forest habitats throughout Colombia have undergone extensive
deforestation. Vi[ntilde]a et al. (2004, pp. 123-124) used satellite
imagery to analyze deforestation rates and patterns along the
Colombian-Ecuadorian border (in the Departments of Putumayo and
Sucumbios, respectively), finding that between 1973 and 1996, a total
of 829
[[Page 59987]]
km\2\ (320 mi\2\) of tropical forests within the study area were
converted to other uses. This corresponds to a nearly one-third total
loss of primary forest habitat, or a nearly 2 percent mean annual rate
of deforestation within the study area.
Since the 1970s, the Colombian Government has encouraged road
construction and colonization projects. The goal is to create links to
the vast and undeveloped Amazonian region, and to open up the Llanos
and Amazonian lowlands for utilization of their natural resources
(Salaman et al. 2007, pp. 10, 89; Salaman et al. 2002, p. 160). In
recent years, this species' habitat has come under increased pressure
with the completion of the Mocoa-Bogot[aacute] highway, the proposed
Puerto As[iacute]s-Florencia road, and the discovery and exploitation
of petroleum and precious metals. All of these factors contribute to an
escalation in human encroachment and associated impacts that degrade
this species' habitat (Salaman et al. 2007, p. 10). The few remaining
forest connections between the upper and lower slopes are under
pressure, even where they are minimally protected.
Five main routes link the lowlands from Colombia's high Andean
interior to other areas. Infrastructure development on the eastern
slope of the Andes in Colombia, as well as adjacent Ecuador, has also
caused significant human population pressures and has led to much
habitat degradation. Increased and improved access roads have led to
the conversion of mature tropical forests for pasture lands, petroleum
products exploitation, and coca plantations (Salaman et al. 2007, p.
89). These road projects to link Colombia with Venezuela and Ecuador
along the entire eastern base of the Andes have contributed to
additional deforestation.
Serran[iacute]a de los Churumbelos National Park
Currently, the Serran[iacute]a de los Churumbelos forest is almost
entirely intact and is owned by the government (Salaman et al. 2007,
pp. 10, 91-92). This mountain range has largely avoided the degree of
human impact that other regions have suffered. However, this is
changing rapidly due to mineral exploration (petroleum and precious
metals) and natural resources (timber and rich organic soils for
agriculture) demands. The Serran[iacute]a de los Churumbelos could
become the focus of large-scale deforestation and colonization in the
near future (Salaman et al. 2007, p. 89). Parque Natural Nacional Cueva
de los Gu[aacute]charos provides some protection to the forests in this
region although it is a small park (approximately 5,000 ha or 12,355
ac), and even here, illegal encroachment occurs (Salaman et al. 2007,
p. 89).
Catatumbo-Bar[iacute] National Park
The primary threat in the Catatumbo-Bar[iacute] National Park (at
the Colombian-Venezuelan border) is deforestation and impacts
associated with coca plantations surrounding the Park (Fundaci[oacute]n
ProAves 2011, pp. 28-29). Coca cultivation has fluctuated for several
years. Over a 4-year study period, it contained about 100 ha (247 ac)
of coca (United Nations Office on Drugs and Crime, undated report, p.
33). A new population of this species was recently recorded at two
locations in this park (Avenda[ntilde]o 2011 in BLI 2014a, p. 2). In
addition, one population in the Cauca valley (fewer than 50 mature
birds) could be affected by the construction of a dam (155 m (508.5 ft)
in height) that could affect its sole breeding cliff. However, the
status of the dam is still unclear (American Bird Conservancy 2012, p.
24).
Ecuador
Ecuador experiences one of the highest deforestation rates in South
America (Mosandl et al. 2008, p. 37). Forested habitat within many
parts of Ecuador has diminished rapidly due to logging, clearing for
agriculture, and road development (Youth 2009, pp. 1-3; Mosandl et al.
2008, p. 37; Sierra 1999, p. 136; Dodson and Gentry 1991, pp. 283-293).
Between the years 1990 and 2005, Ecuador lost a total of 2.96 million
ha (7.31 million ac) of primary forest, which represents a 16.7 percent
deforestation rate, and a total loss of 21.5 percent of forested
habitat since 1990 (Butler 2006b, pp. 1-3; FAO 2003b, p. 1). Much of
the primary moist forest habitat has been replaced with pastures and
scattered trees (Collar et al. 1992, p. 533). Very little suitable
habitat now remains for the species here, and remaining suitable
habitat is highly fragmented (Bass et al. 2010, p. 2; Snyder et al.
2000, p. 122). In the area where this species exists, near the Gran
Sumaco Biosphere Reserve, there are several oil reserves (Celi-
Sangurima 2005, p. 22). However, specific impacts to this species as a
result of oil exploration or extraction activities are unknown.
The colony in Kichwa River Reserve is currently in an area
designated as protected, although it is unclear what these protections
entail. In this area, the local community group Macaw Rio is interested
in conducting ecotourism. Although this colony has persisted for about
150 years (Huatatoca pers comm. in Arcos-Torres and Solano-Ugalde 2008,
p. 72), it likely will be affected by logging and the resulting
deforestation on nearby land. Researchers suggest that the apparent
lack of this species in Ecuador is possibly related to lack of suitable
sites for the formation of breeding colonies, or lack of knowledge
about sites that may be located in inaccessible areas (Arcos-Torres and
Solano-Ugalde 2008, p. 72). We know of no specific threats to the
species in the Kichwa River Reserve, other than those associated with
small population sizes, which is discussed under Small Population Size,
below.
Mexico
Mexico has suffered extensive deforestation (conversion of forest
to other land uses) and forest degradation (reduction in forest biomass
through selective cutting, etc.) over the past several decades
(Commission for Environmental Cooperation (CEC) 2010, pp. 45, 75). In
recent decades, Mexico's deforestation has been rapid (Blaser et al.
2011, pp. 343-344). Between 1990 and 2000, Mexico lost forest
(factoring in natural regeneration of degraded forest and planting of
forest in areas that previously did not have forest) at a net rate of
344,000 ha (850,043 ac) per year (FAO 2010, p. 21). During 1990-2010,
Mexico lost approximately 6 million ha (15 million ac) of forest, and
had one of the largest decreases in primary forests worldwide (FAO
2010, pp. 56, 233). Although Mexico's rate of forest loss has slowed in
the past decade, it still continues. The current rate of net forest
loss in Mexico is 155,000 ha (383,013 ac) per year, with an estimated
250,000-300,000 ha (617,763-741,316 ac) per year degraded (Government
of Mexico (GOM) 2010b, in Blaser et al. 2011, p. 344; FAO 2010, p.
233).
As of 2010, Mexico had 64.8 million ha (160.1 million ac) of forest
(Food and Agriculture Organization (FAO) 2010, p. 228), and 50 percent
of these forests are considered degraded. Projections of lost forested
area by the year 2030 in Mexico are between 10 percent to nearly 60
percent of mature forests lost, and approximately 0 to 54 percent of
regrowth forests lost (CEC 2010, pp. 45, 75). Deforestation via forest
conversion to agricultural uses remains a major driver of land
transformation in Mexico (CEC 2008, p. 24). Agricultural production is
projected to double within the country by 2030 (CEC 2010, pp. 34, 70).
Although some of this increase in production is expected due to an
increase in productivity on previously converted land, total
agricultural land area in Mexico is projected to increase by 6,300 to
41,400 ha (15,568 to 102,302 ac) by 2030 (CEC 2010, p. 75).
[[Page 59988]]
In the range of the military macaw, such as the tropical forest
along the Pacific coast of Mexico, high rates of deforestation have
occurred; slash-and-burn agriculture still occurs along with grazing.
In 2002, it was estimated that the species had suffered a 23 percent
habitat loss within its range in Mexico using a Genetic Algorithm for
Rule-set Prediction (GARP) analysis tool (R[iacute]os-Mu[ntilde]oz
2002, pp. 24, 32). GARP analysis essentially uses ecological
characteristics of known species locations in order to determine its
likely distribution.
A 3-year study documented loss of habitat, particularly trees used
by macaws, in the Tehuacan-Cuicatlan Biosphere Reserve, Sabino Canyon.
In their study, researchers found a total of 170 individual plants of
species consumed by military macaws in the pine forests in an area of
1,500 m\2\ (16,146 ft\2\) in 2005 (Arizmendi 2008, p. 43). By January
2008, eleven (6.5 percent) of these trees had been logged. In the
transitional forest between dry and pine (in an area of 1,000 m\2\ or
10,764 ft\2\), 134 plants were documented in 2005, and by January 2008,
fifteen (11.90 percent) of them had been logged. Arizmendi suggested
that these activities are carried out by local communities, and
suggested that a local environmental education campaign be implemented.
A reduced number of trees limit the availability of adequate food
resources across the landscape. With fewer trees remaining, the area
cannot support the same number of individuals of the species and,
therefore, causes a further reduction in the population. Macaws were
not found in deforested areas, even where one of their important food
sources, Hura polyandra, was left as shade for cattle (Rivera-
Ort[iacute]z et al. 2008, p. 256). As further support, in Jalisco, most
of the sites where macaws were present had little or no habitat loss
(note that none of the sites in Jalisco where military macaws were
located were in protected areas). No macaws were located in sites with
more than 30 percent habitat loss, even though these sites may have had
abundant trees.
Mining
At the Mineral de Nuestra Se[ntilde]ora reserve in C[oacute]sala,
where this species occurs, mining activities are occurring (Rubio et
al. 2007, p. 52; Bonilla-Ruz et al. 2007b, p. 45). This reserve is 12
km (7.5 mi) southeast of C[oacute]sala in Sinaloa, Mexico. This reserve
was created after a joint effort in 1999 between the state, municipal
government, and the Autonomous University of Sinaloa. The Autonomous
University of Sinaloa conducted technical studies to propose the area
as a nature reserve. The university also conducted conservation
projects here which focused on the ``Ecology and Conservation of the
Military Macaw'' and ``Environmental Education and Ecotourism.'' In
2002, the Mineral de Nuestra Se[ntilde]ora reserve was formally
designated. Since then, parrot populations and their habitat here both
within and outside the preserve have been affected by mining activities
taking place in the area (Rubio et al. 2007, p. 52). In early 2005,
mining efforts began on underground development and drilling (Scorpio
Mining 2011, p. 2). The current effect of mining on the species is
unclear.
Peru
There is little to no current published information with respect to
specific threats to this species in Peru (Gasta[ntilde]aga et al. 2011,
entire; JGP Consultants 2011, entire; Lee 2010, entire; Cowen 2009,
entire; Terborgh 2004, entire; Brightsmith 2004, entire). It exists in
several parks that convey some measures of protection (Oliveira et al.
2007, p. 1,235; Terborgh 2004, p. 35). Peru's protected areas are
managed by the General Department of Natural Protected Areas, INRENA,
under the authority of Law No. 26834, Law of Natural Protected Areas,
promulgated in 1997. The Peruvian national protected area system
includes several categories of habitat protection. Habitat may be
designated as any of the following:
(1) Parque Nacional (National Park, an area managed mainly for
ecosystem conservation and recreation);
(2) Santuario (Sanctuary, for the preservation of sites of notable
natural or historical importance);
(3) Reserva Nacional (National Reserve, for sustainable extraction
of certain biological resources);
(4) Bosque de Protecci[oacute]n (Protection Forest, to safeguard
soils and forests, especially for watershed conservation);
(5) Zona Reservada (Reserved Zone, for temporary protection while
further study is under way to determine their importance);
(6) Bosque Nacional (National Forest, to be managed for
utilization);
(7) Reserva Comunal (Communal Reserve, for local area use and
management, with national oversight); and
(8) Cotos de Caza (Hunting Reserve, for local use and management,
with national oversight) (BLI 2008, p. 1; Rodr[iacute]guez and Young
2000, p. 330).
Because the designations of national parks, sanctuaries, and
protection forests are established by supreme decree that supersedes
all other legal claim to the land, these areas tend to provide more
habitat protection than other designations. All other protected areas
are established by supreme resolution, which is viewed as a less
powerful form of protection (Rodr[iacute]guez and Young 2000, p. 330).
This species has been documented in the Tambopata National Reserve,
which is a 275,000-ha (679,540-ac) conservation area created by the
Peruvian Government in 1990. The main purpose was to protect the
watersheds of the Tambopata and Candamo Rivers. This area protects some
of the last pristine lowland and premontane tropical humid forests in
the Amazon. Within the Tambopata National Reserve, there have been
isolated human settlements along stretches of the Malinowski River,
which flows into the Tambopata River. Fewer than 5,000 people inhabit
the Tambopata National Reserve's border area to the north. They make a
living of slash-and-burn agriculture, small-scale gold mining, timber
extraction, and hunting and fishing. One area of Tambopata, including a
buffer zone, was recently described as a ``crisis zone'' (Lee 2010, p.
169). It has been described as being at high risk for illegal
settlement, timber extraction, and mining (Lee 2010, p. 169).
Populations of this species are thought to be in the Manu Biosphere
Reserve and the Bahuaja Sonene National Park in Peru (WCS 2007, p. 1;
Herzog in litt. 2007; Terborgh 2004, pp. 40-41). The problems here are
primarily due to human population growth (Terborgh 2004, pp. 40-41).
Five indigenous groups reside in the Manu Biosphere Reserve--they are
both legal and illegal settlers (Terborgh 2004, pp. 40-41). An
ecological research station has been in place since 1973 in Man[uacute]
National Park (Terborgh 2004, entire), which also adds some protection
to the species. Research has shown that often simply having a long-term
research presence there can help to reduce poaching (Campbell et al.
2011, p. 2). Unlike parks in the United States, in countries such as
Peru, parks and protected areas were formed around the indigenous
tribes that live there (Terborgh 2004, p. 51), and the management and
purpose of the parks often include protection of the rights of
indigenous human communities. This philosophy of park protection and
mandates of parks differs from in the United States, where humans are
viewed as visitors to the parks, rather than permanent residents
(Terborgh 2004, p. 51). In Manu Biosphere Reserve, another potential
threat is oil exploration. Both Shell and Mobil Oil
[[Page 59989]]
have conducted oil exploration activities in this area (Terborgh 2004,
p. 55; ParksWatch 2002, pp. 5, 7). Within Bahuaja, as of 2002, there
were no human establishments within its boundaries (ParksWatch 2002a,
p. 1). However, activities that could affect the military macaw in this
area include gold mining, illegal logging, extraction of forest
resources, and farming (ParksWatch 2002b, p. 1).
Venezuela
There is little published information about the military macaw in
Venezuela (BLI 2014, pp. 1-2; Rodriguez 2004, entire). Here it exists
in the Andes in the Central Coastal Cordillera, and Sierra de
Perij[aacute] (Rodriguez et al. 2004, pp. 375, 378, 379). It has been
found on the north slopes of El [Aacute]vila, Guatopo, Henri Pittier
National Park, Ceroo La Mision, and Sierra de Perij[aacute] National
Park (Desenne and Strahl 1994 in Snyder et al. 2000, p. 125; Fernandez-
Badillo et al. 1994 in Snyder et al. 2000 p. 125). Most of its range in
Venezuela is within protected areas, but as of 2000, threats still were
reported to exist in the protected areas (Snyder et al. 2000, p. 125).
In 2000, Snyder et al. noted that Sierra de Perij[aacute] was being
deforested for narcotics, land speculation, and cattle (p. 125). A
population of this species was recorded for the first time at two
localities at the Catatumbo-Bar[iacute] National Park in the Colombian-
Venezuelan border, extending the previous species' range from the east
slope of the Serran[iacute]a de Perij[aacute] southwards
(Avenda[ntilde]o 2011, p. 2).
Summary of Factor A
Habitat loss, human encroachment, and conversion to agriculture are
the main threats acting on the species throughout its range. These
threats are exacerbated by an inability by range country governments to
adequately manage and monitor the species (see discussion under Factor
D, below). South America had the largest net loss of forest area of all
continents between 2000 and 2005 (Mosandl et al. 2008, p. 38), with a
net loss of 4.3 million ha per year. Although specific, detailed
information about this species' remaining occupied habitat status is
not available for each country, we know that much of this species'
habitat has been lost through conversion of land to farming, forestry,
or other activities (Bonilha and Switkes 2008, p. 17; Etter et al.
2006, p. 369; Renton 2004, p. 13). Conversion of habitat to soy
plantations is now considered to be one of the principal causes of
Amazon deforestation. Deforestation may already have destroyed as much
as 1.2 million ha (3 million ac) in the Amazon. This, combined with
pressures of capture for the pet trade, has severely impacted the wild
population of military macaws. Studies have shown that, over time,
resident bird diversity generally declines as remaining forest becomes
smaller and more fragmented (Turner 1996, pp. 202, 206).
As with most parrots, the military macaw requires large areas of
suitable habitat, including large trees or other nesting cavities for
nesting, feeding, and roosting as well as food sources. Deforestation
and logging is a common form of habitat loss that affects this species
(Benetiz-Diaz 2012, p. 4; R[iacute]os-Mu[ntilde]oz et al. 2009, pp.
502-505). Deforestation via conversion of land to agricultural use is a
threat to military macaws because it directly eliminates forest
habitat, removing the trees that support the species' nesting,
roosting, and dietary requirements. It also results in fragmented
habitat that isolates military macaw populations, potentially
compromising the genetics of these populations through inbreeding
depression and genetic drift (Lande 1995, pp. 787-789; Gilpin and
Soul[eacute] 1986, p. 27). We do not know the exact extent of
deforestation in the range of the military macaw. However, the best
available information indicates that deforestation continues to occur
and affect the species throughout its range, despite protections that
are in place.
Currently the population of military macaws is extremely small
(likely a few thousand individuals), those populations are severely
fragmented, and its suitable habitat is becoming increasingly more
scarce. Therefore, based on the best available scientific and
commercial information, we find that the present or threatened
destruction, modification, or curtailment of habitat or range is a
threat to the military macaw now and in the future.
B. Overutilization for Commercial, Recreational, Scientific, or
Educational Purposes
The trade in wild parrots is common in some areas of South America
(Gasta[ntilde]aga et al. 2011, entire; Cant[uacute]-Guzm[aacute]n et
al. 2008, entire). In its Red List assessment, the IUCN indicates that
the two major threats to the military macaw are habitat loss and
capture for the domestic pet trade (IUCN 2011, p. 1). Many reports
indicate that poaching for the pet trade is still a problem for parrot
species, particularly in poorer countries (Herrera and Hennessey 2007,
entire; Dickson 2005, p. 548). For perspective, in the United States,
captive-bred specimens of this species were recently found offered for
sale for $699 (Basile 2010, p. 2). In 2006, four military macaws were
advertised for sale with an average sale price of $850 (Cant[uacute]-
Guzm[aacute]n et al. 2008, p. 72). Although the scope of the illegal
trade in the military macaw is unknown, poaching can be a lucrative and
relatively risk-free source of income (Dickson 2005, p. 548).
A high percentage of birds die during the process of capturing from
the wild, transporting, and selling them. Because most of these
activities are illegal, it is difficult to accurately determine the
actual mortality rate, but estimates vary between 31 and 90 percent
(Weston and Memon 2009, p. 79; Cant[uacute]-Guzm[aacute]n et al. 2007,
pp. 7, 20, 22, 55, 60). Military macaws mate for life, are long-lived,
and have low reproductive rates. These traits make them particularly
sensitive to the impacts of their removal from the wild (Lee 2010, p.
3; Thiollay 2005, p. 1,121; Wright et al. 2001, p. 711). Wild harvest
can destroy pair bonds, remove potentially reproductive adults from the
breeding pool, and have a significant effect on small populations
(Kramer and Drake 2010, p. 11). These activities adversely affect a
species' population numbers (Pain et al. 2006, p. 322).
Although poaching continues to occur for the pet trade, it has been
found to be significantly lower at protected sites (Pain et al. 2006,
pp. 322-328; Wright et al. 2002, p. 719). Other reports have found that
national or local protection, particularly when local communities are
actively involved in conservation efforts, can successfully reduce nest
take (Pain et al. 2006, p. 328; Chassot et al. 2006, pp. 86-87).
Gonzalez (2003, pp. 437-446) found evidence of poaching, particularly
during nesting seasons, in the Pacaya-Samiria National Reserve, a
protected area in the Loreto Department, Peru, during his 1996-1999
study. However, he also found that poaching decreased during the 1998
harvest season (Gonzalez 2003, p. 444), which he attributed to
increased numbers of birds confiscated by regional authorities, which
may have subsequently discouraged poaching (also see Factor D, below).
A related factor is the destruction of trees in this species'
habitat due to poaching. This species primarily depends on tree-cavity
nests as its habitat. Not only does nest poaching negatively affect
this species by reducing the population size and the number of birds
available to reproduce, it also in some cases destroys this species'
habitat. Several studies have found that poachers will cut down trees
to remove nests. A study conducted in the late 1990s found that in some
cases
[[Page 59990]]
in Peru, poachers cut down the nesting tree in order to access the
nestlings (Gonzalez 2003, p. 443). They also were observed ``hacking''
open the nest cavities to remove chicks (Bergman 2009, pp. 6-8; Low
2003, pp. 10-11). An average of 21 nests was destroyed per poaching
trip (Gonzalez 2003, p. 443). Nest destruction was also reported by
Bergman in Ecuador in 2009 (pp. 6-8).
The military macaw was listed in CITES Appendix II, effective June
6, 1981, and was transferred to CITES Appendix I, effective October 22,
1987. Most of the international trade in military macaw specimens
consists of live birds. Data obtained from the United Nations
Environment Programme--World Conservation Monitoring Center (UNEP-WCMC)
CITES Trade Database show that, during the nearly 6 \1/2\ years that
the military macaw was listed in Appendix II, a total of 1,034 military
macaw specimens were reported to UNEP-WCMC as (gross) exports. Of those
1,034 specimens, 1,019 were live birds and 15 were feathers. In
analyzing these data, it appears that several records may be over-
counts due to slight differences in the manner in which the importing
and exporting countries reported their trade. It is likely that the
actual number of military macaw specimens in international trade during
this period was 973, including 958 live birds and 15 feathers. Fourteen
of the live birds were captive-bred, and the others were reported with
the source unknown. Exports from range countries included: 364 live
birds from Bolivia; 320 from Mexico; 11 from Ecuador; 4 from Venezuela;
and 1 from Argentina.
During the more than 25 years following the transfer to Appendix I
(October 22, 1987 through December 31, 2012, the last year for which
complete data were available at the time the following numbers were
compiled, the UNEP-WCMC database shows a total of 1,894 military macaw
specimens as (gross) exports, including 1,455 live birds, 224
scientific specimens, 213 feathers, 1 body, and 1 trophy (UNEP-WCMC
trade database, accessed May 20, 2014). As noted above, it appears that
some records may be over-counts due to differences in the manner in
which the importing and exporting countries reported their trade. It is
likely that the actual number of live military macaws in international
trade during the 25-year period was 1,301. Of those 1,301 birds, 1,022
were captive-bred or captive-born, and 119 were reported as wild. The
source of the remaining live birds is unknown. Exports from range
countries included: 54 live birds from Mexico; 10 from Argentina; 4
from Venezuela; 2 from Colombia; and 1 from Peru. Annual quantities
exported ranged from a low of 14 live birds during 2006, to 122 live
birds (including 80 exported from South Africa) in 2009. Since 2004,
none of the exports from range countries has been reported as wild
origin.
Argentina, Bolivia, Ecuador, and Mexico
In Argentina, Ecuador, and Venezuela, there is little to no
information available about overutilization. International trade has
diminished, but local trade continues to occur. In Bolivia, a report
published in 2009 indicated that of 17,609 birds (including military
macaws) documented in the market studied in Department of Santa Cruz
(not far from the range of this species), 64 percent of the birds were
found to be adults captured in the wild. Ninety percent (24,707) of the
birds were found to be from the Department of Santa Cruz. A total of
2,604 individuals were from the Department of Tarija, 176 from the
Department of Beni, 20 from Peru, and 12 from Brazil (Herrera and
Hennessey 2009, p. 233). The report indicated that most parrots (some
of which were military macaws) were locally sold, and found that 23,306
were in the city of Santa Cruz, and 4,156 were sent to Cochabamba.
In Mexico, the military macaw is reportedly one of the most sought-
after species in the illegal pet bird trade (Cant[uacute]-Guzm[aacute]n
et al. 2007, p. 38), and poaching remains a concern. In 1995-2005, it
was the fifth most seized Mexican psittacine species by Mexico's
Environmental Enforcement Agency, becoming the fourth most seized
psittacine species in 2007-2010 (p. 52). As an example, at a sinkhole
in El Cielo Biosphere Reserve, a population of approximately 50 birds
was decimated by poaching in the 1980s (Arag[oacute]n-Tapia in litt.
1989 in Snyder et al. 2000, p. 125). In many areas, it nests in
relatively inaccessible cavities on cliff walls, which provide some
protection against the pressures of nest poaching. However, nest
poaching is a severe threat in Jalisco and Nayarit, where the species
nests in tree cavities (Contreras-Gonz[aacute]lez et al. 2007, p. 43;
Renton in litt. 2007 and Bonilla in litt. 2007 in BLI 2011a, pp. 1-2).
Between 2005 and 2006 in Mexico, five military macaws were found for
sale, and the average price was $373 (Cant[uacute]-Guzm[aacute]n et al.
2007, p. 76).
Local residents in Argentina indicated that young chicks are
removed ``for foreigners'' but also noted that it is extremely
difficult due to the difficulty in accessing the species' preferred
nesting sites and the aggressiveness of the macaws (Navarro et al.
2008, pp. 7, 9). Additionally, in Mexico and Ecuador, indigenous
communities have used military macaw feathers for ceremonial and
medicinal practices. However, NGOs are working with these communities
to obtain macaw feathers from aviaries so that the indigenous people
will not hunt the macaws (Renton 2004, p. 14).
Colombia
This species and other Ara macaws are occasionally hunted by
indigenous people in Colombia. In one study, in the Catatumbo-
Bar[iacute] National Park, hunting was found to be concentrated around
the 15 indigenous communities within the 160,000-ha (395,369-ac) park
(Avenda[ntilde]o 2011, p. 2). In 2004, in a cliff-nesting location
along the Cauca River, Colombia, threats to this species included
poaching and loss of foraging trees (Fl[oacute]rez and Sierra 2004, pp.
2-3). They found that, at the Cauca River site, it was common for some
people to remove hatchlings from the nests and sell between 20 to 30
chicks per year on the black market (p. 3). To counteract these
activities, a local awareness campaign was initiated (Fl[oacute]rez and
Sierra 2004, pp. 2-3). As a result of this project, 3,000 Hura
crepitans trees (a species used by the military macaw) were planted by
the local communities, and the awareness campaign appeared to be
effective. Researchers do not believe that hunting pressure is a
serious short-term threat. However, local education and awareness
programs generally need to be ongoing and long-term for them to be
effective, and the local communities need to be aware of the benefits
of conserving species in the wild as well as having an alternative
source of income (i.e., income other than that derived from poaching).
Peru
A recent study in Peru examined nest poaching and illegal trade of
parrots, including the reasons for poaching, and the methods, seasons,
and locations where the sale and actual poaching of parrots occurred.
This study found that this species is still being poached in the wild
(Gasta[ntilde]aga et al. 2011, pp. 79-80), even in protected areas and
despite national protections in place. During the 2007-2008 study,
eight military macaws were found for sale in two out of eight markets
surveyed in Peru (p. 79). Seven of these birds were found in the
Amazonian lowland city, Pucallpa (p. 80). The study also found that,
where protections and enforcement have been implemented such as in
Cusco, there were no parrots for sale in markets. This
[[Page 59991]]
indicates that, although it still continues, poaching is becoming less
frequent due to involvement by NGOs, minimal international demand for
the species, and enforcement by authorities.
Summary of Factor B
Among birds, parrots are the group most subject to commercial trade
(Hutton et al. 2000, p. 14). Parrots have suffered a disproportionate
number of extinctions, in part due to their desirability as pets.
Conservation efforts by the various entities working to ensure long-
term conservation of the military macaw may result in its population
slowly increasing; however, it is likely that the population is still
declining. Even though the military macaw is listed as an Appendix-I
species under CITES and laws have been established within the range
countries to protect this species, we are still concerned about the
illegal capture of this species in the wild. Despite regulatory
mechanisms in place and restricted international trade, poaching is
lucrative and continues to occur. Additionally, because each population
of military macaws is small, with usually fewer than 100 individuals,
poaching is likely to have a significant effect on the species. Based
on the best available scientific and commercial information, we find
that overutilization for commercial, recreational, scientific, or
educational purposes is a threat to the military macaw throughout its
range.
C. Disease or Predation
Disease
Studies of macaws indicate that this species is susceptible to many
bacterial, parasitic, and viral diseases, particularly in captive
environments (Kistler et al. 2009, p. 2,176; Portaels et al. 1996, p.
319; Bennett et al. 1991). Viral diseases seem to be more prevalent and
subsequently more studied in parrots than bacteria and parasites.
Psittacines are prone to many viral infections such as retrovirus, pox
virus, and paramyxo virus, and captive-held birds seem particularly
susceptible (Gaskin 1989, pp. 249, 251, 252). A highly fatal disease,
Pacheco's parrot disease, is also caused by a virus (Simpson et al.
1976, p. 218). After infection from this virus, death occurs suddenly
without apparent sign of sickness other than some mild nasal discharge
and lethargy (Simpson et al. 1976, p. 211). However, as transmission of
this disease is mainly through nasal discharge and feces, it is less
likely to happen in open habitat in the wild than in a confined aviary,
particularly because in the wild this species has been observed to
alternate nest sites based on food availability (Chosset et al. 2004,
pp. 35-39). Another disease, proventricular dilatation disease (PDD),
may be one of the worst diseases known to affect parrots (Kistler et
al. 2008, p. 2). PDD has been documented in several continents in more
than 50 different parrot species and in free-ranging species in at
least five other orders of birds (Kistler et al. 2008, p. 2). It is not
clear if some diseases observed in birds in captivity also occur in the
wild with the same frequency. However, because the populations of
military macaws are small and widely distributed, disease is less of a
concern because diseases tend to be more easily transmitted between
individuals within close range, and wild birds disperse and are not
constantly in close proximity. Also, captive conditions in aviaries
make birds more susceptible to disease where the stress of confinement
combined with inadequate diet can reduce the ability of birds to fight
disease.
We have no evidence of significant adverse impacts to wild
populations of military macaws due to disease. Disease is a normal
occurrence within wild populations. There is no indication that disease
occurs to an extent that it is a threat. Based on the best available
scientific and commercial information, we find that disease is not a
threat to the military macaw in any portion of its range now or in the
future.
Predation
Eggs and chicks are more susceptible to predation than adult macaws
(Arizmendi 2008, p. 44). Chicks and eggs are particularly susceptible
to predation by snakes (Arizmendi 2008, p. 44), but military macaws
select their nests where they are likely to have a high level of
reproductive success. Because military macaws generally construct their
nests in high locations such as canyon cliffs, snake predation is less
of a concern because snakes need tree canopy or vines to climb in order
to gain access to eggs and chicks.
Other predators known to consume this species' eggs include
iguanas, red-tailed hawks (Buteo jamaicensis), turkey vultures
(Carthates aura), and some mammals (Arizmendi 2008, p. 44). In the
Sabino canyon, iguanas were observed near the nesting sites.
Researchers suggested that a predator control program here would
benefit the macaws (Arizmendi 2008, p. 45). Macaws frequently exhibit
alarmed behavior when red-tailed hawks and turkey vultures approach
their nests (Arizmendi 2008, p. 44). In Argentina, a flock of parrots
was attacked by a pair of peregrine falcons (Falco peregrinus), which
also nest in ravines (Navarro et al. 2008, p. 6). However, although
parrots and falcons can be combative, the peregrine falcon, which
normally consumes small mammals and birds, is not thought to be a
natural predator of the military macaw (Bradley et al. 1991, p. 193).
Due to its large size and careful nest site selection, the military
macaw is less susceptible to predation by both land and aerial
predators (Flor[eacute]z and Sierra 2004, pp. 2-3). However, even
limited predation is still a concern in part because removal of
potentially reproductive adults from the breeding pool can have a
significant effect on small populations by destroying macaw mating pair
bonds (Kramer and Drake 2010, p. 11). Additionally, studies on similar
species in similar Andean habitats indicate that vulnerability to
predation by generalist predators increases with increased habitat
fragmentation and smaller patch sizes (Arango-V[eacute]lez and Kattan
1997, p. 140). Because each population of military macaws is small,
with usually fewer than 100 individuals, and because this species mates
for life, even low levels of predation are likely to have a significant
effect on the species.
Summary of Factor C
Diseases associated with military macaws in the wild are not well
documented. Although there is evidence that diseases occur in parrots
in the wild, we found no information that diseases affect this species
to the degree that they are negatively impacting this species in the
wild. Because the populations are distributed across such a large area,
these populations have resiliency against impacts from disease if one
population is affected by a disease outbreak. Conversely, although
disease in the wild is not a concern, predation does remain a concern;
there is evidence that predation on this species occurs often enough
that it can have a significant impact. Because of the species' small
and declining population size, tendency to mate for life, low
reproductive capacity, and existence in isolated habitat fragments,
even minimal predation renders the species more vulnerable to local
extirpations. Therefore, we find that predation, compounded by ongoing
habitat loss and poaching, is a threat to the military macaw.
D. The Inadequacy of Existing Regulatory Mechanisms
Regulatory mechanisms to protect a species could potentially fall
under categories such as regulation of trade, wildlife management,
parks
[[Page 59992]]
management, or forestry management. Regulatory mechanisms could be at
the local, national, or international levels.
International Wildlife Trade (CITES)
A specimen of a CITES-listed species may be imported into or
exported (or reexported) from a country only if the appropriate permit
or certificate has been obtained prior to the international trade and
it is presented for clearance at the port of entry or exit. The
Conference of the Parties (CoP), which is the decisionmaking body of
the Convention and comprises all its member countries, has agreed on a
set of biological and trade criteria to help determine whether a
species should be included in Appendix I or II. The military macaw is
listed in Appendix I. For Appendix-I species, both an export permit (or
reexport certificate) must be issued by the country of export and an
import permit from the country of import must be obtained prior to
international trade. An export permit for species listed in either
Appendix I or II may only be issued if the country of export determines
that:
The export will not be detrimental to the survival of the
species in the wild (CITES Article III(2) and Article IV(2));
The specimen was legally obtained according to the animal
and plant protection laws in the country of export;
For live animals or plants, they are prepared and shipped
for export to minimize any risk of injury, damage to health, or cruel
treatment; and
For Appendix I species, an import permit has been granted
by the importing country.
Except in certain cases, such as specific scenarios for approved
captive-breeding programs, the import of an Appendix-I species requires
the issuance of both an import and export permit. Import permits are
issued only after the importing country determines that it will not be
used for primarily commercial purposes (CITES Article III(3)) and that
the proposed recipient of live animals or plants is suitably equipped
to house and care for them. Thus, with few exceptions, Appendix-I
species cannot be traded for commercial purposes.
The CITES Treaty requires Parties (member countries) to have
adequate legislation in place for its implementation. Under CITES
Resolution Conference 8.4 (Rev. CoP15) and related decisions of the
CoP, the National Legislation Project evaluates whether Parties have
adequate domestic legislation to successfully implement the Treaty
(CITES 2011a). In reviewing a country's national legislation, the CITES
Secretariat evaluates factors such as:
Whether a Party's domestic laws prohibit trade contrary to
the requirements of the Convention,
Whether a Party has penalty provisions in place for
illegal trade, and if they have designated the responsible Scientific
and Management Authorities, and
Whether a Party's legislation provides for seizure of
specimens that are illegally traded or possessed.
The CITES Secretariat has determined that the legislation of
Argentina, Colombia, Mexico, and Peru is in Category 1, meaning they
meet all the requirements to implement CITES. Bolivia, Ecuador, and
Venezuela were determined to be in Category 2, with a draft plan, but
not enacted (https://www.cites.org, SC62 Document 23, pp. 7-8). This
means the Secretariat determined that the legislation of Bolivia,
Ecuador, and Venezuela meet some, but not all, of the requirements for
implementing CITES. Based on the decrease in reported international
trade, CITES and the range countries for this species have effectively
controlled legal international trade of this species. Therefore, we
find CITES is an effective mechanism for preventing overexploitation
for international trade in this species.
Parks and Habitat Management
We are focusing our evaluation of the potential threats to this
species primarily to parks for the following reasons. Most suitable
habitat, primary forest, only remains in these protected areas. The
best available information suggests that this species is now mostly
found in protected areas such as parks, in part because this is where
suitable habitat remains for the species. Additionally, the majority of
the information available regarding the potential threats to the
species pertains to the parks, where the species is usually found. Our
rationale is supported by Cowen, who noted that encounter rates for
large macaw species were generally higher in primary forests (2008, p.
15), which tend to be located in areas with protected status.
Throughout this species' range, we found that many of the threats that
occur to this species are the same or similar. Threats generally
consist of various forms of habitat loss or degradation. Each range
country for this species has protections in place, but for reasons such
as limited budgets and limited enforcement capabilities, the laws and
protections are generally not able to adequately protect the species.
Research has found that tropical parks have been surprisingly
effective at protecting ecosystems and species within boundaries
designated as parks or other protected status despite underfunding and
pressures for resources (Oliveira et al. 2007, p. 1,235; Bruner et al.
2001, p. 126; Terborgh 1999, entire). Bruner's study found that
protected areas are especially effective in preventing land clearing.
It found that, in 40 percent of parks, land that had formerly been
under cultivation and that was incorporated into park boundaries had
actually recovered. This subsequently led to an increase in vegetative
cover. The study also found that 83 percent of parks were successful at
mitigating encroachment (Bruner et al. 2001, p. 125). It concluded that
the conditions inside the parks were significantly better than in their
surrounding areas (Bruner et al. 2001, p. 125). Oliveira et al. found
that forests in conservation units were four times better at protecting
against deforestation than unprotected areas (2007, p. 1,235). However,
despite these protections, this species has experienced threats such
that their populations are now so small (generally fewer than 100 in
each population) that any pressure now has a more significant effect.
Parks, without management, are often insufficient to adequately protect
the species. Our analysis of regulatory mechanisms is discussed
essentially on a country-by-country basis, beginning with Argentina,
and is summarized at the end. Conditions in specific parks are
discussed below.
Argentina
In 2007, Argentina enacted a law mandating minimum standards for
the environmental protection of native forests (Ley de Bosques).
However, the federal government has not fully enforced the law, and
provincial governments are not in full compliance with it (DiPaola et
al. 2008, p. 2). Argentina lacks adequate protections of its natural
environments; there is a lack of environmental awareness and commitment
from the government to adequately protect its resources (FAO 2007, pp.
43-44, 59-60). Provinces usually allow landowners to decide whether to
maintain forest cover or deforest the land. The absence of a serious
land use planning strategy, particularly during the past 20 years, has
led to significant habitat degradation (FAO 2007, p. 60). The threat to
native forests has remained particularly high in the Salta Province. As
a result, a coalition of indigenous communities and nongovernmental
organizations filed for injunctive relief
[[Page 59993]]
in Argentina's highest court to attempt to combat deforestation
(DiPaola et al. 2008, p. 2). In this case, the court mandated
deforestation activities to be halted pending the completion of a
cumulative environmental impact study. The decision forced the Salta
Province to comply with the deforestation moratorium imposed by the
Forestry Law, and pressured the Province to comply with the other key
provision of the law by completing an environmental land use plan
(DiPaola et al. 2008, p. 2). Although the Forestry Law is in place and
the court case has set a precedent for compliance with this law, the
area where this species occurs in Argentina to the best of our
knowledge remains largely unprotected (Navarro et al. 2008, pp. 7, 9).
Bolivia
This species primarily inhabits the parks and protected areas in
Bolivia's Andean region (Herzog 2011, pers. comm.). National parks are
intended to be strictly protected; however, some areas where the
species occurs are also designated as areas of integrated management,
which are managed for both biological conservation and the sustainable
development of the local communities. Bolivia attempts to balance
natural resource uses; however, it is one of the poorest countries in
South America (MacLeod 2009, p. 6; CIA World Factbook, accessed
December 6, 2011), and subsequently has competing priorities. As of
2005, Bolivia had 5 national parks, 6 national park and integrated
management natural areas, 1 national park and indigenous territory (or
communal lands), 4 national reserves, 2 biosphere reserves, and 3
integrated management natural areas (ParksWatch 2005, p. 1). These make
up Bolivia's National System of Protected Areas ((SNAP) Servicio
Nacional de Areas Protegidas). Below are the designations and their
relevant categorizations of protections (eLAW 2003, p. 3).
(1) Park, for strict and permanent protection of representative
ecosystems and provincial habitats, as well as plant and animal
resources, along with the geographical, scenic and natural landscapes
that contain them;
(2) Sanctuary, for the strict and permanent protection of sites
that house endemic plants and animals that are threatened or in danger
of extinction;
(3) Natural Monument, to preserve areas such as those with
distinctive natural landscapes or geologic formations, and to conserve
the biological diversity contained therein;
(4) Wildlife Reserve, for protection, management, sustainable use,
and monitoring of wildlife;
(5) Natural Area of Integrated Management, where conservation of
biological diversity is balanced with sustainable development of the
local population; and
(6) ``Immobilized'' Natural Reserve, a temporary (5-year)
designation for an area that requires further research before any
official designations can be made and during which time no natural
resource concessions can be made within the area (Supreme Decree No.
24,781 1997, p. 3).
The foundation of Bolivia's laws is largely based on Bolivia's 1975
Law on Wildlife, National Parks, Hunting, and Fishing (Decree Law No.
12,301 1975, pp. 1-34), which has the fundamental objective of
protecting the country's natural resources. This law governs the
protection, management, utilization, transportation, and selling of
wildlife and their products; the protection of endangered species;
habitat conservation of fauna and flora; and the declaration of
national parks, biological reserves, refuges, and wildlife sanctuaries,
regarding the preservation, promotion, and rational use of these
resources (Decree Law No. 12,301 1975, pp. 1-34; eLAW 2003, p. 2).
Later, Bolivia passed an overarching environmental law in 1992 (Law No.
1,333 1992), with the intent of protecting and conserving the
environment and natural resources. Studies have shown that protected
areas have been successful in providing protection from poaching,
logging, and other forest damage, especially when compared to
unprotected areas (Lee 2010, p. 3; Killeen et al. 2007, p. 603;
Oliveira et al. 2007, p. 1,234; Asner 2005, p. 480; Ribeiro et al.
2005, p. 2; Gilardi and Munn 1998, p. 641). However, pressures on the
parks' resources are increasing; these are described below.
Within the Greater Madidi-Tambopata Landscape, activities that
could negatively affect this species occur, and there are competing
priorities within these protected areas. The GMTL is divided into three
contiguous areas, with two different management categories: A strictly
protected National Park in two sections that total 1,271,000 ha
(3,140,709 ac), and a natural integrated management area with 624,250
ha (1,542,555 ac), where conservation and sustainable development of
the local communities is the main purpose (Conservation Strategy Fund
(CSF) 2006, p. 29). The most significant activities that are having a
negative impact or could in the future in this area are the
construction of a highway within Madidi, mining for natural resources
such as gold, drilling for oil, and a planned hydroelectric dam
(ParksWatch 2011b, p. 8; https://www.amazonfund.eu/art-oil-madidi.html,
accessed September 13, 2011; Chavez 2010, pp. 1-2). There is limited
legal hunting of this species occurring here, but in the areas
surveyed, this species was described as common and not exploited
(Hosner et al. 2009, p. 226). Timber extraction still occurs in some
areas (WorldLand Trust 2010, p. 1). In the rainforest and foothill
forest of Serran[iacute]a Sadiri within Madidi, roads in the late 1990s
spurred a rise in the unsustainable logging of the area's mahogany
trees, which were the most valuable tree at the time (World Land Trust
2010, pp. 1-2). Within the Apolobamba protected area, uncontrolled
clearing, extensive agriculture, grazing, and ``irresponsible'' tourism
are ongoing (Auza and Hennessey 2005, p. 81). Habitat degradation and
destruction from grazing, forest fires, and timber extraction are
ongoing in other protected areas, such as Tunari National Park
(Department of Cochabamba), where suitable habitat exists for this
species (De la Vie 2004, p. 7).
Bolivia's national policy is to decentralize decisionmaking, and
responsibility for land planning and natural resource management is
increasingly shifting to local and regional governments (Wildlife
Conservation Society (WCS) 2009, pp. 2-5). However, the
decentralization process is occurring without sufficient personnel,
staff training, and operational funds. There is little information as
to the actual protections that Bolivia's laws and protected areas
confer to military macaws, despite the laws in place at the national
level for its wildlife. Threats to the species and its habitat include
unsustainable land use practices, illegal logging, mining, road
building, oil extraction, illegal animal trade, and hunting, which are
all still occurring within this species' habitat (MacLeod 2009, p. 6;
WCS 2009, pp. 2-5). The mechanisms in place are inadequate at reducing
the threat of habitat destruction and human disturbance within these
protected areas.
Colombia
The Colombian Government has enacted and ratified numerous domestic
and international laws, decrees, and resolutions for managing and
conserving wildlife and flora. Colombia currently has 54 areas that
have protected status (El Sistema Nacional de Areas
[[Page 59994]]
Protegidas (SINAP); National Natural Parks of Colombia 2011). Of those,
33 have been declared Important Bird Areas (IBAs). The protected area
designations are as follows: national parks (parques nacionales), flora
and fauna sanctuaries (santuarios de fauna y flora), flora sanctuaries
(santuarios de flora), nature reserves (reserva natural), and unique
natural areas ([aacute]rea natural [uacute]nica) (Law 165 of 1994).
Small populations of this species occur in several reserves and
protected areas in Colombia (Strewe and Navarro 2003, p. 32). These
protected areas in Colombia offer various degrees of protection to the
species.
In 2003, conservation priorities were identified for its bird
species, a conservation corridor was designed, and a habitat
conservation strategy within the San Salvador valley was developed
(Strewe and Navarro 2003, p. 29). The private Buena Vista Nature
Reserve was established and protects approximately 400 ha (988 ac) of
tropical wet lowland forest and wet premontane forest on the northern
slope of the Sierra Nevada. It encompasses extensive primary forests
along an altitudinal gradient of 600 to 2,300 m (1,968 to 7,545 ft) and
forest patches and secondary forest at elevations between 450 to 600 m
(1,476 to 1,968 ft). The reserve is adjacent to the Sierra Nevada de
Santa Marta National Park and the Kogi-Malayo Indian reserve (Strewe
and Navarro 2003, p. 29).
A conservation project focusing on the coffee zone of the middle
R[iacute]o Fr[iacute]o is ongoing, and its goal is to create a
conservation corridor connecting natural habitats and shade-grown
coffee plantations (Strewe and Navarro 2004, p. 51). The establishment
of the private nature reserve, Buena Vista, was the first step to
conserve the foothill forest ecosystems. This was done in close
cooperation with a local organization, Grupo Ecologico Defensores de la
Naturaleza-Campesinos de Palomino (Strewe and Navarro 2003, pp. 34-35).
The Pro-Sierra Nevada de Santa Marta Foundation (FPSNSM) maintains a
permanent monitoring station at Buena Vista nature reserve. FPSNSM is
working toward sustainable development projects in cooperation with
local communities, national park units, and coffee-grower committees in
the region. This includes educational campaigns to limit hunting.
Habitat management takes place on private lands in the lowlands and
foothills of the San Salvador valley to reduce the pressure on the
remaining natural forest habitats, including a reforestation program
using native tree species. Additionally, forest reserves have been
established as part of a network of private nature reserves in the
valley (Strewe and Navarro 2003, pp. 35-36).
Resource management in Colombia is highly decentralized. Colombian
environmental management has been divided between the national and
regional levels since the 1950s. Governmental institutions responsible
for oversight appear to be under resourced (ITTO 2006, p. 222) and
unable to adequately manage species such as the military macaw.
Resources are managed within local municipalities by one of 33
``Autonomous Regional Corporations'' known as CARs (Corporaciones
Aut[oacute]nomas Regionales) (Blackman et al. 2006, p. 32). CARs are
described as corporate bodies of a public nature, endowed with
administrative and financial autonomy to manage the environment and
renewable natural resources, implemented through Law 99 of 1993 (p.
32). Each department (analogous to U.S. state designations) within
Colombia is managed by a separate local entity. These corporations
grant concessions, permits, and authorizations for forest harvesting
(ITTO 2006, p. 219).
As of 2005, 40 percent of Colombia's public resources were managed
by local municipalities, making Colombia one of the most decentralized
countries in terms of forestry management in Latin America (Blackman et
al. 2006, p. 36). Monitoring of resource use and forest development
authorized by these corporations is conducted mostly by local
nongovernmental organizations. The International Tropical Timber
Organization (ITTO) considers the Colombian forestry sector to be
lacking in law enforcement and on-the-ground control of forest
resources, with no specific standards for large-scale forestry
production, no forestry concession policies, and a lack of transparency
in the application of the various laws regulating wildlife and their
habitats (ITTO 2006, p. 222). Consequently, there is currently no
effective vehicle for overall coordination of species management for
multijurisdictional species such as the military macaw.
Fundaci[oacute]n ProAves developed a conservation plan for 2010 to 2020
for several parrot species, including the military macaw (Botero-
Delgadillo and P[aacute]ez 2011, p. 7). However, it is unclear if or
when it will be adopted by the Government of Colombia.
Additionally, despite protections, forest loss continues almost
unabated in the mountains of the Sierra Nevada, demonstrating that
formal protections and regulatory mechanisms are inadequate. In this
area, El Congo Reserve currently may be the only secure nesting site
for the military macaw, but it is too small (40 ha; 99 ac) to conserve
viable populations.
Efforts are occurring in Colombia to protect and monitor its
species, although they do not appear to be adequate to combat the
threats to this species. One management tool that Colombia has recently
developed is a bird-watching strategy in these protected areas to
monitor and report on bird species such as the military macaw, in
conjunction with ecotourism (National Natural Parks of Colombia 2011).
Despite the efforts in place, there is a lack of information available
about the status of this species and its habitat in Colombia. There is
no clear information about the status of the species in Colombia,
particularly its population trend. We are unable to determine that this
conservation strategy will sufficiently mitigate threats to the
military macaw, nor are we able to find that the regulatory mechanisms
in place in Colombia are adequate. The species population is small in
Colombia, and threats to its habitat still exist.
Ecuador
In Ecuador, the military macaw is considered to be very rare
(Arcos-Torres and Solano-Ugalde 2008, p. 72). It has been observed in
the areas of Sumaco and Zamora-Chinchipe (Youth 2009, p. 1; Snyder et
al. 2000, p. 125) and recently at Kichwa River Reserve (Reserva Kichwa
R[iacute]o), within the Gran Sumaco Biosphere Reserve Guacamayos
(Arcos-Torres and Solano-Ugalde 2008, p. 72). This species is
categorized as endangered ``en peligro de extinci[oacute]n'' (Arcos-
Torres and Solano-Ugalde 2008, p. 69) in Ecuador. It is protected by
Decree No. 3,516 of 2003 (Unified Text of the Secondary Legislation of
the Ministry of Environment) (EcoLex 2003b, pp. 1-2 and 36). This
decree summarizes the laws governing environmental policy in Ecuador
and provides that the country's biodiversity be protected and used
primarily in a sustainable manner.
Habitat destruction is ongoing and extensive in Ecuador (Mosandl et
al. 2008, p. 37; Butler 2006b, pp. 1-3; FAO 2003b, p. 1). Unsustainable
forest harvest practices likely continue to impact the military macaw's
habitat. In 2004, Ecuador Law No. 17 (Faolex 2004, pp. 1-29) amended
the Forest Act of 1981 (Law No. 74) to include five criteria for
sustainable forest management: (i) Sustainable timber production; (ii)
the maintenance of forest cover; (iii) the conservation of
biodiversity; (iv) co-responsibility in
[[Page 59995]]
management; and (v) the reduction of negative social and environmental
impacts (ITTO 2006, p. 225; Aguilar and Vlosky 2005, pp. 9-10). In
2001, the Ecuadorian Government worked with the private sector to
develop a system of monitoring and control of forest harvest practices.
However, in 2003, the Supreme Court of Ecuador declared the control
system unconstitutional, and new control systems were being developed
(ITTO 2006, p. 225). Approximately 70 percent of the forest products
harvested are harvested illegally, or are used as fuel wood, or are
discarded as waste (ITTO 2006, p. 226; Aguilar and Vlosky 2005, p. 4).
Because the extractive harvesting industry is not monitored, the extent
of the impact is unknown; however, the best available information
indicates that habitat degradation negatively affects this species in
Ecuador.
The Ecuadorian Government recognizes 31 different legal categories
of protected lands (e.g., national parks, biological reserves, geo-
botanical reserves, bird reserves, wildlife reserves, etc.). The colony
in Kichwa River Reserve Macaw receives some legal protections by being
in a Reserve. However, a study published in 2002 concluded that,
although 14 percent of Ecuador is categorized as national reserve
network (Sierra et al. 2002, p. 107), the system does not provide
adequate protection for its ecosystems. As of 2006, the amount of
protected land (both forested and nonforested) in Ecuador totals
approximately 4.67 million ha (11.5 million ac) (ITTO 2006, p. 228).
However, only 38 percent of these lands have appropriate conservation
measures in place to be considered protected areas according to
international standards (i.e., areas that are managed for scientific
study or wilderness protection, for ecosystem protection and
recreation, for conservation of specific natural features, or for
conservation through management intervention) (IUCN 1994, pp. 17-20).
The ITTO, as of 2006, considered ecosystem management and conservation
in Ecuador, including effective implementation of mechanisms that would
protect the military macaw and its habitat, to be lacking (ITTO 2006,
p. 229).
Although this colony has persisted for about 150 years (Huatatoca,
pers. comm. in Arcos-Torres and Solano-Ugalde 2008, p. 72), it may be
affected by logging and the resulting deforestation on nearby land
(Arcos-Torres and Solano-Ugalde 2008, p. 72). The best available
information indicates that on-the-ground enforcement of Ecuador's laws,
oversight of the local jurisdictions, and implementing and regulating
activities are ineffective in conserving the military macaw and its
habitat in Ecuador. Researchers suggest that the apparent lack of this
species in Ecuador is related to lack of existing suitable sites (large
areas containing appropriate feeding, nesting, and breeding habitat)
for the formation of breeding colonies. The governmental institutions
responsible for natural resource oversight in Ecuador appear to be
under-resourced, and to our knowledge, there is a lack of law
enforcement on the ground. Despite the creation of a national forest
plan, the best available information indicates there is a lack of
capacity to implement this plan due to inconsistencies in application
of regulations, and discrepancies between actual harvesting practices
and forestry regulations. These inadequacies have facilitated logging,
clearing for agriculture, subsistence farming, and road development.
Habitat conversion and alteration are ongoing within Ecuador, including
within protected areas.
Mexico
This species is listed as endangered and is regulated under the
general terms of the General Law of Ecological Balance and
Environmental Protection (Ley General del Equilibrio Ecol[oacute]gico y
Protecci[oacute]n al Ambiente (LGEEPA)), the General Wildlife Law (Ley
General de Vida Silvestre (LGVS)), and also under CITES (CEC 2003,
unpaginated). NOM-059-ECOL-2010 establishes a list of wildlife species
classified as either in danger of extinction (endangered), threatened,
under special protection, or probably extinct in the wild (Government
of Mexico 2002, p. 6). All use of endangered and threatened species
requires a special permit from the Secretariat of the Environment and
Natural Resources (Secretar[iacute]a del Medio Ambiente y Recursos
Naturales (SEMARNAT). SEMARNAT's main goal is to protect, restore, and
conserve its ecosystems and natural resources. Under Mexico's General
Wildlife Law, the use of these protected species, including the
military macaw, may be authorized only when priority is given to the
collection and capture for restoration, repopulation, and
reintroduction activities (Comisi[oacute]n Nacional Para El
Conocimiento y Uso de la Biodiversidad 2009, unpaginated; CEC 2003,
unpaginated).
International trade of Mexico's wildlife is also managed by
SEMARNAT. In 2008, Mexico passed Article 60_2 to amend its General
Wildlife Law. The article bans the capture, export, import, and
reexport of any species of the Psittacidae (parrot) family whose
natural distribution is within Mexico (Cant[uacute] and S[aacute]nchez
2011, p. 1). It allows authorizations for the removal of individuals
from the wild to be issued only for conservation purposes, or to
accredited academic institutions for scientific research. However, it
does not appear to be adequate based on investigations of trade of
Mexico's native parrot species.
The military macaw falls under the jurisdiction of several other
laws in Mexico. The General Law on Sustainable Forest Management (Ley
General de Desarrollo Forestal Sustenable (LGDFS 2003)) governs forest
ecosystems in Mexico, including military macaw habitat. This law
formalizes the incorporation of the forest sector in a broader
environmental framework. Under this law, harvesting of forests requires
authorization from SEMARNAT. It also requires that harvesting forests
is based on a technical study and a forest management plan (GOM 2010,
p. 24). A number of additional laws complement the 2003 law in
regulating forest use. The LGEEPA regulates activities for protecting
biodiversity and reducing the impact on forests and tropical areas of
certain forest activities; the LGVS governs the use of plants and
wildlife found in the forests; the General Law on Sustainable Rural
Development (Ley General de Desarrollo Rural Sustentable) provides
guidance for activities aimed at protecting and restoring forests
within the framework of rural development programs; and the Agrarian
Law (Ley Agraria) governs farmers' ability to use forest resources on
their land (Anta 2004, in USAID 2011, unpaginated).
Another law regulating portions of the military macaw's habitat is
the National System of Protected Natural Areas (Sistema Nacional de
[Aacute]reas Naturales Protegidas (SINANP)). These protected natural
areas are created by presidential decree, and the activities in them
are regulated under the LGEEPA, which requires that the protected
natural areas receive special protection for conservation, restoration,
and development activities (Comisi[oacute]n Nacional de [Aacute]reas
Naturales Protegidas (CONANP) 2011, unpaginated). These natural areas
are categorized as: Biosphere Reserves, National Parks, Natural
Monuments, Areas of Natural Resource Protection, Areas of Protection of
Flora and Fauna, and Sanctuaries (CONANP 2011, unpaginated).
Conservation strategies in Mexico rely heavily on natural protected
areas, and biosphere reserves comprise most of the designated protected
area in the country (Figueroa and Sanchez 2008, pp. 3324,
[[Page 59996]]
3234). The military macaw occurs in or near at least four biosphere
reserves. Although some areas where this species occurs have protected
status, Figueroa and Sanchez (2008, entire) found that, for example,
the Sierra Gorda Biosphere Reserve was ineffective (as opposed to
effective or weakly effective). This study specifically evaluated the
effectiveness of Mexico's protected areas for preventing land use and
land cover change. It assessed the effectiveness of national protected
areas (NPAs) by quantifying (1) the rate of change and (2) the total
extent of change, between 1993 and 2002, as well as (3) the percentage,
in 2002, of areas transformed by human use; transformed areas included
agriculture, cultivated and induced pastures, human settlements, and
forestry plantations. The rate of change of transformed areas inside
each NPA was also compared with that estimated for an equivalent area
surrounding the NPA. They selected 69 federal decreed NPAs (out of 160
NPAs decreed in Mexico) that were 1,000 ha (2,471 ac) or larger, which
is the minimum area for conserving ecosystems in Mexico (Figueroa and
Sanchez 2008, p. 3,225; Ord[oacute][ntilde]ez and Fl[oacute]rez-Villela
1995, p. 11). The study found that, overall, only approximately 54
percent of protected areas, including 65 percent of biosphere reserves,
were effective.
Peru
In Peru, this species is listed as vulnerable under Supreme Decree
No. 034-2004-AG (2004, p. 276,855), and its protections fall under the
jurisdiction of the National Institute of Natural Resources (Instituto
Nacional de Recursos Naturales, INRENA). This Decree prohibits hunting,
take, transport, and trade of protected species, except as permitted by
regulation. The military macaw is thought to occur in at least three
areas with protected status in Peru. The Peruvian national protected
area system includes several categories of habitat protection (refer to
Factor A). National reserves, national forests, communal reserves, and
hunting reserves are managed for the sustainable use of resources (IUCN
1994, p. 2). The designations of national parks, sanctuaries, and
protection forests are established by supreme decree that supersedes
all other legal claim to the land and, thus, these areas tend to
provide some form of habitat protection (Rodr[iacute]guez and Young
2000, p. 330). However, limited information is available with respect
to the status of this species in Peru. We do not know if the occurrence
of the military macaw within protected areas in Peru actually protects
the species or mitigates threats to the species, and to what extent
these protections are effective.
Venezuela
In Venezuela, the military macaw is thought to exist in two parks:
El [Aacute]vila National Park and Henri Pittier National Park. Limited
information about the status of this species is available in Venezuela.
Henri Pittier National Park (107,800 ha; 266,380 ac) was declared the
first national park in Venezuela in 1937. This park is the largest
national park of the Cordillera de la Costa (Coastal Mountain Range)
region. The principal threats to this park include: fire, human
encroachment, solid waste buildup, pollution, hunting, and limited
resources for effective park management (ParksWatch 2011g,
unpaginated). In many cases, the intensity of threats has increased.
Prior to 1994, a team of government representatives, NGOs,
universities, and aviculturists in Venezuela had developed both an
action plan for the conservation of parrots and a book containing
information on parrot biology (Morales et al. 1994, in Snyder 2000, p.
125). However, currently, it is unclear what conservation initiatives
are occurring.
El [Aacute]vila National Park (81,800 ha; 202,132 ac in size), is
located along the central stretch of the Cordillera de la Costa
Mountains in northern Venezuela. The most immediate threats to the park
are forest fires and illegal settlements, which occur primarily near
Caracas (ParksWatch 2011f, unpaginated). ParksWatch notes that the
areas closest to the city have experienced more problems in the more
isolated northern slope and eastern sector of El [Aacute]vila. Other
threats in this park include the presence of nonnative plants and
poaching.
Summary of Factor D
In Argentina, Ecuador, Peru, and Venezuela, we recognize that
conservation activities are occurring, and that these activities may
have a positive effect on the species at the local population level.
Parrots, in general, are long-lived with low reproductive rates, traits
that make them particularly sensitive to poaching and other threats
such as habitat loss (Lee 2010, p. 3; Thiollay 2005, p. 1,121; Wright
et al. 2001, p. 711). The primary threats to this species historically
have been the loss of habitat and capture for the pet trade (Strewe and
Navarro 2003, p. 33). Since regulatory mechanisms such as CITES and the
WBCA have been put into place, particularly since 1992, much of the
legal international trade in the military macaw has declined (see
Factor B discussion, above). However, those pressures prior to the
military macaw's listing under CITES and the WBCA contributed
significantly to the decline in population numbers for this species.
Since then, the species' habitat has become fragmented, its range has
reduced, and its populations have more difficulty finding suitable
habitat.
Each of these countries has enacted laws to protect its wildlife
and habitat. The populations of this species in these four countries
are likely to number from fewer than 100 to a few hundred individuals.
There are numerous threats acting on this species; its populations have
severely declined. In some cases, the actual causes of decline may not
be readily apparent and a species may be affected by more than one
threat in combination. Habitat conservation measures within these range
countries do not appear to sufficiently mitigate future habitat losses.
Habitat loss and degradation continue to occur within these countries;
the best available information does not indicate that the existing
regulatory mechanisms have mitigated these threats in the range of this
species. Because these populations of this species are very small in
these countries, any impact is likely to have a significant impact on
the species; therefore, we are unable to conclude that regulatory
mechanisms in place for this species and its habitat are adequate.
Bolivia, Colombia, and Mexico have enacted various laws and
regulatory mechanisms for the protection and management of this species
and its habitat. Although information available is limited, the best
evidence suggests that the military macaw exists in small populations
in several large protected areas within these countries. As discussed
under Factor A, the military macaw prefers primary forests and
woodlands and complex habitat that offers a variety of food sources.
Its suitable habitat has been severely constricted due to
deforestation. In these three countries, there is evidence of threats
to this species due to activities such as habitat destruction and
degradation, poaching, construction of roads, and mining, as well as
decreased viability due to small population sizes, despite the
regulatory mechanisms in place. We acknowledge that research and
conservation programs are occurring in these countries. However, based
on the best available information, we find that the existing regulatory
mechanisms for these countries are either inadequate or inadequately
enforced in order to protect the species or to mitigate ongoing habitat
loss and degradation, poaching, and the severe population decline of
this species.
[[Page 59997]]
Habitat conservation measures within these range countries do not
appear to sufficiently mitigate future habitat losses.
Based on the best available information, we are unable to conclude
that the existing regulatory mechanisms currently in place sufficiently
mitigate threats to the military macaw throughout its range. Therefore,
we find that the existing regulatory mechanisms are inadequate to
mitigate the current threats to the continued existence of the military
macaw throughout its range now and into the future.
E. Other Natural or Manmade Factors Affecting Its Continued Existence
Small Population Size
Small, declining populations can be especially vulnerable to
environmental disturbances such as habitat loss (O'Grady 2004, pp. 513-
514). Removal of a few birds from a population of 100 can have a
greater effect than removal of a few birds from larger populations. In
order for a population to sustain itself, there must be enough
reproducing individuals and habitat to ensure its survival.
Conservation biology defines this as the ``minimum viable population''
requirement (Grumbine 1990, pp. 127-128). This requirement may be
between 500 and 5,000 individuals depending on variability, demographic
constraints, and evolutionary history. The military macaw occurs in
relatively small populations (ranging from a few pairs to approximately
100 individuals, with the total population size that is likely no
greater than a few thousand). The military macaw relies on specific
habitat to provide for its breeding, feeding, and nesting.
Historically, the military macaw existed in much higher numbers in more
continuous, connected habitat. Its suitable habitat is becoming
increasingly limited, and is not likely to expand in the future.
The combined effects of habitat fragmentation and other factors on
a species' population can have profound effects and can potentially
reduce a species' respective effective population by orders of
magnitude (Gilpin and Soul[eacute] 1986, p. 31). For example, an
increase in habitat fragmentation can separate populations to the point
where individuals can no longer disperse and breed among habitat
patches, causing a shift in the demographic characteristics of a
population and a reduction in genetic fitness (Gilpin and Soul[eacute]
1986, p. 31). This is especially applicable for a species such as the
military macaw that was once wide-ranging. It has lost a significant
amount of its historical range due to habitat loss and degradation.
Furthermore, as a species' status continues to decline, often as a
result of deterministic forces such as habitat loss or overutilization,
it will become increasingly vulnerable to other impacts. If this trend
continues, its ultimate extinction due to one or more stochastic
(random or unpredictable) events becomes more likely. The military
macaw's current occupied and suitable range is highly reduced and
severely fragmented. The species' small population size, its
reproductive and life-history traits, and its highly restricted and
severely fragmented range increase this species' vulnerability to other
threats.
Climate Change
Consideration of ongoing and projected climate change is a
component of our analysis under the ESA. The term ``climate change''
refers to a change in the mean, variability, or seasonality of climate
variables over time periods of decades or hundreds of years
(Intergovernmental Panel on Climate Change (IPCC) 2007, p. 78).
Forecasts of the rate and consequences of future climate change are
based on the results of extensive modeling efforts conducted by
scientists around the world (Solman 2011, p. 20; Laurance and Useche
2009, p. 1,432; Nu[ntilde]ez et al. 2008, p. 1; Margeno 2008, p. 1;
Meehl et al. 2007, p. 753). Climate change models, like all other
scientific models, produce projections that have some uncertainty
because of the assumptions used, the data available, and the specific
model features. The science supporting climate model projections as
well as models assessing their impacts on species and habitats will
continue to be refined as more information becomes available. While
projections from regional climate model simulations are informative,
various methods to downscale projections to more localized areas in
which the species lives are still imperfect and under development
(Solman 2011, p. 20; Nu[ntilde]ez et al. 2008, p. 1; Marengo 2008, p.
1). The best available information does not indicate that climate
change is impacting this species such that it is a threat.
Summary of Factor E
A species may be affected by more than one threat acting in
combination. Impacts typically operate synergistically, particularly
when populations of a species are decreasing. Initial effects of one
threat factor can later exacerbate the effects of other threat factors
(Gilpin and Soul[eacute] 1986, pp. 25-26). Further fragmentation of
populations can decrease the fitness and reproductive potential of the
species, which will exacerbate other threats. Within the preceding
review of the five factors, we have identified multiple threats that
may have interrelated impacts on this species. The most significant
threats are habitat loss and poaching, particularly because the species
has such a small and fragmented population, and it requires a large
range and variety of food sources. Lack of a sufficient number of
individuals in a local area or a decline in their individual or
collective fitness may cause a decline in the population size, despite
the presence of suitable habitat patches. For example, the species'
behavior of not nesting in areas where depredation or disturbance is
likely may mean that a nest site is ``abandoned'' before nesting is
even attempted. Thus, the species' productivity may be reduced because
of any of these threats, either singularly or in combination. These
threats occur at a sufficient scale so that they are affecting the
status of the species now and will in the future.
In addition, the species' current range is highly restricted and
severely fragmented. The species' small population size, its
reproductive and life-history traits, and its highly restricted and
severely fragmented range increase the species' vulnerability to
adverse natural events and manmade activities that destroy individuals
and their habitat. The susceptibility to extirpation of limited-range
species can occur for a variety of reasons, such as when a species'
remaining population is already too small or its distribution too
fragmented such that it may no longer be demographically or genetically
viable (Harris and Pimm 2004, pp. 1,612-1,613). Therefore, we find that
the species' small population size, in combination with other threats
identified above, is a threat to the continued existence of the
military macaw throughout its range now and in the future.
Finding and Status Determination for the Military Macaw
We find that this species is endangered based on the above
evaluation, and we are listing this species as endangered due to the
threats described above that continue to act on this species. Within
the preceding review of the five factors, we identified multiple
threats that may have interrelated impacts on the species. For example,
the productivity of military macaws may be reduced because of the
effects of poaching and habitat loss, which are expected to continue to
act on the species in the future. In cases where populations are very
small, species mate
[[Page 59998]]
for life, and birds produce small clutch sizes, these effects are
exacerbated. The susceptibility to extirpation of species with small
and declining populations can occur for a variety of reasons, such as
when a species' remaining population is already too small or its
distribution too fragmented such that it may no longer be
demographically or genetically viable (Harris and Pimm 2004, pp. 1,612-
1,613). This species exists generally in very small and fragmented
populations, usually in areas with some form of protected status in
Mexico, Bolivia, Peru, and Colombia, and to a limited extent Ecuador,
Venezuela, and Argentina. Its life-history traits (such as mating for
life and small clutch size) make it particularly susceptible to
extinction because its populations are so small. Based on our review of
the best available scientific and commercial information pertaining to
the five factors, we found that many of these threats are similar
throughout the species' range.
In four of the countries (Argentina, Ecuador, Peru, and Venezuela),
the populations are extremely small, and very little information about
the status of the species is available in many parts of its range. It
is not necessarily easy to determine (nor is it necessarily
determinable) which potential threat is the operational threat.
However, we believe that these threats, either individually or in
combination, are likely to occur at a sufficient geographical scale to
significantly affect the status of the species. Additionally, although
we do not have precise genetic information about populations throughout
this species' range, it is likely that there is some genetic transfer
between populations. We believe this based on its demonstrated ability
to fly long distances in search of food sources (Chosset and Arias
2010, p. 5). The most significant threat, habitat loss and degradation,
is prevalent throughout this species' range. Its suitable habitat has
severely contracted, and habitat loss is likely to continue into the
future. We do not find that the factors affecting the species are
likely to be sufficiently ameliorated in the foreseeable future.
Therefore, we find that listing the military macaw is warranted
throughout its range, and we propose to list the military macaw as
endangered under the ESA.
Great Green Macaw
Taxonomy
The great green macaw (Ara ambiguus or ambigua, Linnaeus, 1766;
Bechstein, 1811) is in the parrot (Psittacidae) family. It is known by
various common names such as lapa verde, Buffon's macaw, Guacamayo
verde mayor, Guara verde, and Papagayo de Guayaquil. It occurs as two
subspecies. The nominate subspecies, Ara a. ambiguus, occurs from
Honduras to north-west Colombia. The subspecies A. a. guayaquilensis
occurs in western Ecuador (Rodriguez-Mahecha et al. 2002, p. 116;
Fj[euml]ldsa et al. 1987, pp. 28-31). There are believed to be only
around 100 individuals of A. a. guayaquilensis in two areas in Ecuador.
This subspecies has a smaller bill with greener underside of the flight
and tail feathers than the nominate subspecies (Juniper and Parr 1998,
p. 423). Avibase and ITIS both recognize these subspecies (https://www.itis.gov and https://avibase.bsc-eoc.org/avibase.jsp, accessed May
5, 2014).
There is no universally accepted definition of what constitutes a
subspecies, and the use of the term subspecies varies among taxonomic
groups (Haig and D'Elia 2010, p. 29). To be operationally useful,
subspecies must be discernible from one another (i.e., diagnosable) and
not merely exhibit mean differences (Patten and Unitt 2002, pp. 28,
34). This element of discernibility is a common thread that runs
through all subspecies concepts. Regarding the great green macaw, all
populations or subspecies of Ara ambigua essentially face similar
threats, all are generally in the same region (Central and northern
South America), and all have small populations. In other words, they
are not discernible between populations. For the purpose of this
proposed rule and based on the best available information, we recognize
all populations of great green macaws as a single species.
Description
This species ranges between 77 and 90 cm (30 and 35 inches) in
length and has a red frontal band above a large black bill, bare facial
features with black lines, blue flight feathers on the superior
feathers and olive inferior feathers, blue lower back, and orange tail
(Juniper and Parr 1998, pp. 423-424). It is the second largest New
World macaw. This species is not sexually dimorphic, meaning there are
no differences in appearance between males and females of the same
species. The great green macaw is very similar in appearance to the
military macaw, but the military macaw has more prominent blue coloring
on its hind neck, has darker plumage, and is smaller. These two species
are also separated geographically.
Range, Observations, and Population Estimates
The great green macaw is patchily distributed in a 100,000-km\2\
(38,610-mi\2\) area (BLI 2014b, p. 2). In addition to occupying humid
tropical forests primarily in Central America (Costa Rica, Honduras,
Nicaragua, and Panama), there are small remnant populations in western
Ecuador, as well as northern Colombia (Berg et al. 2007, p. 1; Chassot
et al. 2006, p. 7). Although there may be some interaction between
populations, the great green macaw is fragmented into seven isolated
populations throughout its distribution due to habitat loss (Monge et
al. 2009, pp. 159, 174).
Deforestation has reduced this species' habitat and concentrated
its population into primarily five areas: the border of Honduras and
Nicaragua, the border of Nicaragua and Costa Rica, the Dari[eacute]n
region of Panama and Colombia, and two very small populations in
Ecuador (Hardman 2011, p. 8; Monge et al. 2009, p. 159).
Population estimates were made in the 1990s and early 2000s. In
1993, the population estimate was 5,000 individuals; in 2000, the
population was estimated to be between 2,500 and 10,000 birds (BirdLife
International 2014b, p. 4; Rodr[iacute]guez-Mahecha 2002a). The global
population is now likely less than 2,500 mature individuals (or less
than 3,700 with juveniles included) (Monge et al. 2009, pp. 213, 256);
however, the actual population is far from clear. Although historical
observations are useful for assessing the range of the species, they
may also be biased because surveys may not have sampled randomly. Thus,
historical population estimates of this species may not be accurate.
Although the population in Costa Rica is increasing, the population
continues to be very small (Monge et al. 2010, p. 16), and researchers
believe that the global population of this species is decreasing
(Botero-Delgadillo and P[aacute]ez 2011, p. 91). Specific information
about the range and population estimate for each country is discussed
below.
[[Page 59999]]

Colombia
Historically in Colombia, it was found in the north of the
Serran[iacute]a de Baud[oacute],the West Andes, and east of the upper
Sin[uacute] valley (Snyder et al. 2000, pp. 121-123). In the late
1990s, this species was observed in Los Kat[iacute]os National Park,
around Utr[iacute]a National Park in Serran[iacute]a de Baud[oacute]
(Salaman in litt. 1997), and the Choc[oacute] area of western Colombia
(Angehr in litt. 1996 in Snyder et al. 2000, pp. 121-123; Ridgley
1982). This species' potential geographical range is 51,777 km\2\
(19,991 mi\2\), which includes two core areas in Sierra Nevada de Santa
Marta and in the center of Antioquia Department of Columbia (Salaman et
al. 2009, p. 21; Monge et al. 2009, unpaginated; Quevado-Gill et al.
2006, p. 15). The total Columbian population is currently unclear but
it is now believed to primarily exist in Los Kat[iacute]os National
Park, which borders the Dari[eacute]n region in Panama. It was also
recently observed in the area of Sabanalarga, Antioquia (Quevado-Gill
et al. 2006, p. 15). Even though the largest population is thought to
be in the northern Dari[eacute]n border region with about 1,700 adults,
researchers believe this is an estimate without a strong basis (Botero-
Delgadillo and P[aacute]ez 2011, p. 91). The populations in Colombia
are highly localized, and this number could be an overestimate (Botero-
Delgadillo and P[aacute]ez 2011, p. 91).
Costa Rica
The great green macaw historically inhabited forests along the
Caribbean lowlands of Costa Rica (Chosset et al. 2004, p. 32). The
population has increased in that area since 1994, when there was an
estimate of 210 birds. The population appears to have fluctuated; in
2004, it was estimated that a maximum of 35 pairs were breeding in
northern Costa Rica (Chosset et al. 2004, p. 32). A survey conducted in
2009 reported a population estimate of 302 in Costa Rica (Monge et al.
2009, p. 12); another estimate was that there was a total of 275 birds
in Costa Rica in 2010 (Chassot 2010 pers. comm. in Hardman 2011, p.
11).
Approximately 67,000 ha (165,561 ac) of great green macaw breeding
territory now remains in Costa Rica (Chun 2008, p. v), which is less
than 10 percent of its original suitable habitat (Monge et al. 2010, p.
15; Chosset et al. 2004, p. 38). Potential great green macaw breeding
habitat, excluding Ecuador, is defined by the density of almendro
trees, which this species uses for its primary feeding and nesting
substrate. Almendro trees are found only on the Atlantic coast from
southern Nicaragua down through Costa Rica and Panama and into
Colombia, primarily at altitudes below 900 m (2,953 ft). Based on the
assumption that great green macaw breeding pairs require 550 ha (1,359
ac) of non-overlapping habitat, Chun postulated that northern Costa
Rica could support about 120 breeding pairs (2008, p. 110). Chun notes
that even the forested areas identified as individual ``patches''
through a geographic information system (GIS) program do not
necessarily represent areas of forest with continuous canopy cover
(indicating complex, fairly undisturbed habitat that is likely to
contain nutritional needs for this species). Although these patches of
forest are technically connected at some level, they are for the most
part highly porous and discontinuous, and no analysis was performed to
filter out stands that might be porous or discontinuous. There are some
areas in its potential range that are above the elevation threshold for
almendro trees, and do not meet the criteria for suitable habitat.
Ecuador
In Ecuador, there may only be one viable population. This
population exists in the Cerro Blanco Protected Forest, which is 6,070
ha (15,000 ac) outside of Guayaquil in Guayas Province (Villate et al.
2008, p. 19). This population is believed to be approximately 10
individuals. An overall estimate of 60 to 90 individuals in Ecuador in
2011 may be optimistic (Horstman pers. comm. in Hardman
[[Page 60000]]
2011, p. 12). Ecuador's population in 2002 was estimated to be between
60 and 90 individuals (Monge et al. 2009, p. 256), but the population
was reported to be rapidly decreasing. In addition, this is a decline
from 1995, when the population was estimated to be approximately 100
birds in Esmeraldas Province alone (Waugh 1995, p. 10). Between 1995
and 1998, some individuals were observed in the Playa de Oro area along
the Santiago River (Jahn 2001, pp. 41-43). In 2005, the species was
described as being found in scattered forest remnants in coastal
Ecuador from Guayas to Esmeraldas Province (Horstman 2005, p. 3).
In addition to the small population in the Cerro Blanco Protected
Forest, recently reported to be about 10 individuals, there may be
another small group in the Rio Canande Reserve, which is a humid
tropical forest and is located in the Esmeraldas province in coastal
northern Ecuador (Horstman pers. comm. in Hardman 2011, p. 12). Rio
Canande Reserve (1,813 ha or 4,478 ac) is one of eight reserves managed
by another NGO, the Jocotoco Foundation. The most recent population
census in Ecuador was conducted in the provinces of Esmeraldas, Santa
Elena, and Guayas. Five individuals were recently observed in the
Bosque Protector Chong[oacute]n Colonche; one macaw was observed at the
Hacienda El Molino, near the Cerro Blanco Protected Forest; and two
macaws were seen at Rio Canande (Horstman 2011, p. 16). The Cordillera
(mountain range) de Chong[oacute]n-Colonche is on the central pacific
coast of Ecuador, located in the provinces of Guayas and Manabi. Some
individual great green macaws have also been observed at Hacienda
Gonzalez 40 km (25 mi) northwest of Guayaquil; however, these
individuals may be part of the same population found in Cerro Blanco.
In summary, the majority of individuals are believed to be in
Esmeraldas Province, and very small numbers remain in the
Chong[oacute]n-Colonche mountain range, Guayas.
Honduras
In 1983, the great green macaw was common in lowland rain forests
in the Moskitia (Mosquitia) area and eastern Olancho (Marcus 1983, p.
623). The region known as the Moskitia includes both eastern Honduras
and northern Nicaragua. Historically, the species was reported to occur
in the areas of Juticalpa and Catacamas in Olancho (Marcus 1983, p.
623). The species was observed daily in the Pl[aacute]tano River area
in flocks of more than 10 individuals and almost daily in the Patuca
River area, usually in pairs (Barborak 1997 in Snyder et al. 2000, pp.
121-123). In August 1992, macaws were recorded on the Patuca River at
Pimienta upstream from Wampusirpe (Wiendenfeld in Monge et al. 2009, p.
242). Currently, this species exists in the Rio Pl[aacute]tano
Biosphere Reserve (800,000 ha or 1,976,843 ac), which has been
described as one of the most important reserves in Central America
(Anderson et al. 2004, p. 447).
Nicaragua
In Nicaragua, the great green macaw is found primarily in lowland,
tropical, and rain forest, as well as pine barrens, primarily in the
Bosawas Reserve in the north and around the Indio-Ma[iacute]z and San
Juan rivers in the south (Stocks et al. 2007, p. 1503; Martin[eacute]z-
S[aacute]nchez 2007; Chassot 2004, p. 36). The name Bosawas is derived
from three significant geographic landmarks that delineate the
reserve's core zone limits: The Bocay River, Mount Saslaya, and the
Waspuk River. The Bosawas protected area contains habitat that is vital
to the species. In the buffer zone of the Indio-Ma[iacute]z Biological
Reserve, great green macaw nesting locations have been identified. The
Indio-Ma[iacute]z Biological Reserve is located in Nicaragua just
across the San Juan River at the northern border of Costa Rica, and is
nearly 264,000 ha (652,358 ac) in size. The Nicaragua and Costa Rica
macaw populations intermix; macaws have been observed crossing the San
Juan River, which separates Nicaragua and Costa Rica. As of 2006, in
the Quezada, Bijagua, Samaria, and La Juana communities, five macaw
nests had been located during surveying. As of 2010, 35 active nests
had been documented in the Indio-Ma[iacute]z Biological Reserve (Monge
et al. 2010, p. 16).
In 1999, Powell et al. estimated that the Nicaraguan great green
macaw population could be 10 times the size of the population in Costa
Rica. In 2008, a population viability analysis was conducted that
indicated the size of the great green macaw population in Nicaragua was
661 individuals (Monge et al. 2010, p. 21). In 2009, a population
census was conducted, during which 432 macaws were observed. The
researchers suggest that the ``average population'' in Nicaragua is 532
(Monge et al. 2010, p. 13). This 2009 study yielded an estimated
population of 834 individuals in Costa Rica and Nicaragua combined
(Monge et al. 2010, p. 21).
Panama
In Panama, the great green macaw is believed to inhabit the
following areas: Bocas del Toro, La Amistad, northern Veraguas, Colon,
San Blas, Dari[eacute]n, and Veraguas South (Monge et al. 2009,
unpaginated). The species has been described as locally fairly common
near Cana, Alturas de Nique, in 2005 (Angehr in litt. 2005). As of
2009, the historical distribution in Panama was described as not well
known due to lack of information (Monge et al. 2009, p. 68). The most
viable population is believed to be in Dari[eacute]n National Park,
Panama, which borders Colombia (Monge et al. 2009, p. 68; Angehr in
litt. 1996 in Snyder et al. 2000, pp. 121-123; Ridgley 1982).
Researchers believe the Dari[eacute]n area may contain the largest
overall population of the great green macaw. However, there is little
recent information to confirm this (Monge et al. 2009, p. 68).
Dari[eacute]n National Park is the largest national park in Panama, and
one of the largest tropical forest protected areas in Central America
(The Nature Conservancy (TNC) 2011, p. 1). The Dari[eacute]n region
encompasses nearly 809,371 ha (2 million acres) of protected areas,
including Dari[eacute]n National Park and Biosphere Reserve, Punta
Pati[ntilde]o Natural Reserve, Brage Biological Corridor, and two
indigenous reserves (TNC 2011, p. 1). La Amistad, an area that may have
a fairly viable population, connects suitable habitat in Panama such as
Cerro Punta, Rio Pl[aacute]tano, and the Dari[eacute]n region, and
connects the remote hills of Bocas del Toro Province with habitat in
Costa Rica. La Amistad is approximately 200,000 ha (500,000 acres) in
area.
Summary of Population Estimate
The global population of great green macaws is estimated to be
between 2,500 and 3,700 mature individuals (BLI 2014b, p. 4; Chassot
and Arias 2012, p. 61; Monge et al. 2009, p. 213; Jahn in litt. 2005,
2007, unpaginated). Based on the best available information from
experts, the total population is likely between 1,000 and 3,000
individuals (Botero-Delgadillo and P[aacute]ez 2011, p. 91; Monge et
al. 2009, p. 213; Monge et al. 2009b, p. 68). In Ecuador, the
population is estimated to be between 30-40 individuals (Horstman in
litt in BLI 2014, p. 3). In 2009, a census was conducted in Costa Rica
and Nicaragua (Monge et al. 2010, p. 13). A total of 173 individuals
were observed in the Costa Rican study area, and 432 individuals were
observed in the Nicaraguan study area during the breeding season (Monge
et al. 2010, p. 22), with the areas of M[oacute]nico, Romerito, and
Bartola having the highest estimated abundance at the time of each
census. The population of the great green macaw for Costa Rica is
currently estimated to be approximately 302 individuals, and the
population for
[[Page 60001]]
Nicaragua is roughly estimated to be 834 individuals (Monge et al.
2010, p. 22). Species with strict habitat requirements such as the
great green macaw are particularly subject to population size
overestimation, because they are unlikely to be present in suboptimal
habitat despite those habitats being included as part of the species
range (Jetz et al. 2008, p. 116-117). Thus, additional surveys are
needed, and ground-truthing (gathering data regarding where the species
is located) is essential to obtain accurate population estimates for
this species.
Habitat and Life History
The great green macaw inhabits humid lowland foothills and
deciduous forests generally below 600 m (1,968 ft), but also may occur
between 1,000 and 1,500 m (3,281 and 4,921 ft) depending on suitable
habitat, which is primarily based on the presence of almendro (Dipteryx
panamensis) trees. The type of habitat preferred by the great green
macaw is an ecosystem where the almendro tree and Pentacletra macroloba
(oil bean tree) dominate (Chassot et al. 2006, p. 35). This species'
nests have been found in Carapa nicaraguensis (caobilla), Enterolobium
schomburgkii (guanacaste blanco), Goethalsia meiantha, Prioria
copaifera (cativo), and Vochysia ferruginea (botarrama) trees (Chosset
and Arias 2010, p. 14; Powell et al. 1999). Nests have been observed in
large trees, with cavities that are nearly 20 m (66 ft) above ground
(Rodriguez-Mahecha 2002, p. 119). Great green macaws have been observed
to use the same nesting cavity for many years if they are undisturbed,
although they may alternate nest sites each year (Chun 2008, p. 102).
Reproductive capability is generally reached between ages 5 and 6 years
(Chassot et al. 2004, p. 34). The great green macaw mates for life, and
nests in deep cavities (usually of almendro trees) from December to
June (Chassot et al. in Villate et al. 2008, p. 19; Monge et al. 2002,
p. 39). The incubation time is 26 days and the nesting period is 12 to
13 weeks (Rodriguez-Mahecha et al. 2002, p. 119). After the breeding
season, individuals disperse from the lowlands to higher forests in the
mountains in search of food (Powell et al. 1999 in Chosset et al. 2004,
p. 38).
The great green macaw has been observed in flocks of up to 18
individuals, and has been observed traveling long distances on the
Caribbean slope. Macaws are strong fliers and are known to travel
hundreds of kilometers (Chosset and Arias 2010, p. 5; Chosett et al.
2004, p. 36). During a study in the late 1990s, macaws fitted with
radio transmitters demonstrated that macaws migrate seasonally based on
food availability, and were found to travel between 40 and 58 km (25 to
36 mi) while in search of food (Chosset et al. 2004, p. 35).
Diet
The great green macaw has been observed feeding on fruits of 37
tree species (Berg et al. 2007, p. 2; Chassot et al. 2006, p. 35).
While it is closely associated with the almendro tree, its diet varies
based on location. In Ecuador, it was observed feeding on the following
tree species: Cordia eriostigma (totumbo), Cynometra sp. (cocobolo),
Ficus trigunata (matapalo), Ficus sp. (higuer[oacute]n), Psidium
acutangulum (Guayaba de monte), Chrysophyllum caimito (caimito), and
Vitex gigantea (tillo blanco or pechiche) (Berg et al. 2007, p. 2;
Waugh 1995, p. 7). In other parts of its range, it has also been
observed feeding on Cavanillesia platanifolia (NCN), Cecropia litoralis
(pumpwood or trumpet tree), Centrolobium ochroxylum (amarillo de
guayaquil), Cochlospermum vitifolium (buttercup tree), Lecythis ampla
(sapucaia), Leucaena trichodes (NCN), Odroma pyramidalis (NCN),
Pseudobombax guayasen (NCN), Pseudobombax millei (beldaco), Rafia
species (believed to be palms), Sloanea spp., Symphonia globulifera
(NCN), and Terminalia valverdeae (guarapo) (Berg et al. 2007, p. 6).
One preferred plant species, Cynometra bauhiniifolia (NCN), produced
more food than nine other species (Berg et al. 2007, p. 1). In another
study, two of the most important sources of food for the great green
macaw, in addition to the almendro tree, were found to be Sacoglottis
trichogyna (titor, rosita, or manteco) and Vochysia ferruginea (NCN)
(Herrero-Fernandez 2006, p. 9; Chassot et al. 2006, p. 35). S.
trichogyna fruits were observed to be its preferred food when D.
panamensis was scarce or unavailable in Costa Rica (Chassot et al.
2004, p. 34).
Almendro Trees
The great green macaw is closely associated with almendro trees
(Dipteryx panamensis) for feeding and nesting in the majority of its
range (Chun 2008, p. iv; Chosset et al. 2004, p. 34). Because the great
green macaw is highly dependent on the almendro tree, we are describing
almendro tree habitat, its life history, and factors that affect its
habitat. The almendro tree (also known as the tropical almond or
mountain almond tree) is a member of the pea family (Fabaceae;
Papilionoideae) and bears compact, single-seeded drupes. The seeds are
encased in a thick woody endocarp that has been observed to persist on
the forest floor for up to 2 years (Hanson 2006, p. 68). This tree
species is only located in southern Nicaragua, Costa Rica, Panama, and
Colombia, where it grows primarily in the lowlands of the Atlantic
plains. They require an annual rainfall of 3 to 5 m (approximately 10
to 16 ft) (Schmidt 2009, p. 14) for optimal growth. A 2008 study
reported that nearly 90 percent of all great green macaw nests
identified in northern Costa Rica are located within hollowed cavities
of large almendro trees (Chun 2008, p. 109). Additionally, almendro
trees were found to provide 80 to 90 percent of both the macaw's food
and nesting needs. Great green macaw pairs tend to select nesting trees
that are surrounded by relatively dense stands of reproducing almendro
trees (Chun 2008). Almendro tree fruit sustains the adults, chicks,
nestlings, and fledglings over the course of the breeding and
development season, which coincides with the peak production of
almendro fruit (November through March).
Likely pollinators of the almendro tree are bees within the genera
Bombus, Centris, Melipona, Trigona, and Epicharis (Thiele 2002 in
Hanson 2006, p. 3; Flores 1992, pp. 1-22; Perry et al. 1980, p. 310).
These trees are referred to as ``emergent'' because they are the
tallest trees in the forest. Almendro trees can grow to over 46 m (150
ft) and reach a diameter of 1.5 m (4.92 ft). Three hundred-year-old
trees have been documented, but research suggests that the almendro
tree has a maximum potential age of 654 years (Fichtler et al. 2003 in
Schmidt 2009, p. 15).
Wood from the almendro tree is heavy, commercially valuable, and
yields the highest prices on local markets (Rodriguez and Chaves 2008,
p. 5). It is used for furniture, floorings, bridges, railroad ties,
boats, marine construction, handicrafts, veneers, industrial machinery,
sporting equipment, springboards, and agricultural tool handles
(Schmidt 2009, p. 16). Almendro outsells every other tree species on
the Costa Rican timber market (Grethel and Norman 2009 in Schmidt 2009,
p. 77; Rodriguez and Chaves 2008, p. 5). It was listed in Appendix III
of CITES by Costa Rica in 2003 and by Nicaragua in 2007 (https://www.cites.org). A species is unilaterally listed in Appendix III by a
country in the native range of that species, at the request of that
country. Article II, paragraph 3, of CITES states that ``Appendix III
shall include all species which any Party identifies as being
[[Page 60002]]
subject to regulation within its jurisdiction for the purpose of
preventing or restricting exploitation, and as needing the cooperation
of other parties in the control of trade.'' For the export of specimens
of an Appendix-III species from a country that has listed the species,
the Management Authority in that country of export needs to determine
that the specimens were not obtained in contravention of that country's
laws. In addition to CITES protections, a recent decision by the fourth
Chamber of Costa Rica's Supreme Court in 2008 required the Ministry of
Environment and Energy (MINAE, or Ministerio de Ambiente y Energia) to
abstain from the use, exploitation, or extraction of almendro trees
(Chun 2008, p. 113).
Recent research found that this tree species is much more
restricted to lowland habitat than previously described; it is
predicted to occur between 45 and 125 m (147 to 410 ft) in elevation,
in part based on its soil requirements (Schmidt 2009, p. iv; Chun 2008,
p. 109). The almendro tree is best adapted to areas with high levels of
rainfall and acidic clay soils with good drainage below elevations of
500 m (1,640 ft) such as the Atlantic lowlands of Costa Rica (Schmidt
2009, p. iv). Almendro trees require at least 2,000 millimeters (mm)
(79 inches) of rainfall per year for optimal growth (Schmidt 2009, p.
69).
Great green macaw breeding pairs are believed to require a home
range of 550 ha (1,359 ac) (Chun 2008, p. 105). Because the great green
macaw requires such a large range, and is strongly associated with
almendro trees, range countries such as Nicaragua and Costa Rica have
developed conservation plans for the almendro tree. Almendro trees
commonly occur at a density of less than one adult tree per hectare
(Hanson et al. 2008 in Schmidt 2009, p. 14; Hanson et al. 2006, p. 49).
The highest density recorded was 4 trees per hectare (Chaverri and
L[oacute]pez 1998). In one area of Costa Rica that was surveyed for
almendro trees, of 140,178 ha (56,728 ac) surveyed, 20 percent
exhibited densities of 0.50 almendro trees per hectare or more, and 50
percent had densities of 0.20 trees per ha or more (Chun 2008, p. 103).
Due to their important role in the ecosystem, particularly with
respect to the great green macaw, conservation efforts have focused on
the almendro tree. These trees not only provide habitat to many
wildlife species such as the great green macaw, but they also play a
significant role in the ecosystem. One conservation strategy for the
great green macaw is to protect 30,159 ha (74,493 acres) of primary,
secondary, and mangrove forest that remains in this species' nesting
habitat. Another conservation strategy has been to establish almendro
tree plantations. Due to its open crown structure, almendro has a
relatively translucent canopy that produces only moderate shade, which
allows for the production of shade canopy crops such as pineapple and
cacao (Schmidt 2009, p. 19). These almendro plantations are being
researched for several reasons, particularly due to the almendro tree's
ability to resist decay, its ability to capture carbon dioxide, and its
role in the ecosystem (Schmidt 2009, p. 11). Additionally, almendro
trees have been identified as the most promising species for long-term
carbon sink reforestation projects in Costa Rica (Redondo-Brenes 2007,
p. 253; Redondo-Brenes and Montagnini 2006, p. 168).
In Ecuador, the great green macaw is not dependant on almendro
trees, although it still inhabits humid lowland areas (Juniper and Parr
1998, p. 424). In this habitat, the great green macaw prefers Lecythis
ampla (salero) in the Esmeraldas rainforest, Cynometra bauhiniaefolia
(cocobolo) as a primary food source, and pigio (Cavanillesia
platanifolia) as a nest tree (Chassot et al 2007, p. 1; Berg et al
2007, pp. 1-3).
Conservation Status
There are various protections in place for the great green macaw at
the international, national, and local levels. At the international
level, this species is listed as endangered on the IUCN Red List due to
continuous loss of habitat, hunting, and poaching of this species for
the pet trade (BLI 2013). IUCN's Red List classifies species as
endangered (extinction probability of 20 percent within 20 years) or
critically endangered (extinction probability of 50 percent within 10
years) based on several criteria, including limited or declining ranges
or populations. However, the status under IUCN conveys no actual
protections. This species is listed in Appendix I of CITES. Appendix I
includes species threatened with extinction that are or may be affected
by international trade, and are generally prohibited from commercial
trade. Refer to the discussion above for the military macaw for
additional information about CITES. The great green macaw's
conservation status in each country is discussed below and in more
detail under Factor D.
Colombia
The great green macaw is listed as Vulnerable on Colombia's Red
List (Renjifo et al. 2002, p. 524). It has protected status in Los
Kat[iacute]os National Park, Utr[iacute]a National Park, Paramillo
National Park, and Farallones de Cali National Natural Park (Rodriguez
et al. 2002, pp. 120-121). The largest population of the great green
macaw is believed to exist in the Dari[eacute]n Endemic Bird Area (EBA)
023, which encompasses southern Panam[aacute] and northwestern
Colombia. However, there are no reliable population estimates for this
area (Botero-Delgadillo and P[aacute]ez 2011, p. 91; Jahn in litt.
2004). Colombia developed a National Action Plan for the Conservation
of Threatened Parrots (Plan Nacional de Acci[oacute]n para la
Conservaci[oacute]n de los Loros Amenazados), which was in effect until
2007. The ProAves Foundation, an NGO in Colombia, has been active in
parrot conservation since 2005. Other than NGO involvement, it is
unclear what proactive, effective protections are in place for this
species.
Costa Rica
The great green macaw is considered to be endangered in Costa Rica
(Monge et al. 2010, p. 22; Herrero 2006, p. 6; Executive Order No.
26435-MINAE). Several intense conservation initiatives are underway for
this species in Costa Rica. In 2001, a committee was formed to
investigate a corridor for the conservation of this species' habitat.
As a result, the San Juan-La Selva Biological Corridor was formed to
connect the Indio Ma[iacute]z Biological Reserve in southeastern
Nicaragua with the Central Volcanic Cordillera Range in Costa Rica.
This links Costa Rica's La Selva Biological Station in the north to the
Barra del Colorado Wildlife Reserve and National Park and Protective
Zone of Tortuguero on Costa Rica's Caribbean coast. In addition, the
conservation team lobbied for the establishment of the Maquenque
National Wildlife Refuge to protect the macaw's breeding habitat
(Hardman 2011, p. 10; Chun 2008, p. 98). This corridor makes up a part
of the larger MesoAmerican Biological Corridor, which has been proposed
to connect protected habitat from the Yucatan Region in southern Mexico
and Belize to the Dari[eacute]n National Park in Panama (https://www.greatgreenmacaw.org/BiologicalCorridor.htm, accessed October 25,
2011).
The San Juan-La Selva binational corridor links existing protected
wild areas. There is also an extended part to the northwest that
includes the El Castillo area. The goal of this initiative is to
provide linkages to 29 protected areas involving 1,311,182 ha
(3,240,001 ac) (Chassot et al. 2006, p. 85). Because macaws are known
to move hundreds of
[[Page 60003]]
kilometers (Chosset and Arias 2010, p. 5), these linkages should allow
this species better access to different habitats so that it is able to
meet its nutritional and nesting requirements. In addition to
containing key conservation sites for the great green macaw, the
corridor connects the vast expanse that includes Punta Gorda Natural
Reserve, Cerro Silva Natural Reserve, and Fortaleza Inmaculada
Concepci[oacute]n de Mar[iacute]a Historic Monument (Chassot et al.
2006, p. 85). The corridor also provides connections among unprotected
forest patches in Costa Rica in addition to providing connections to
protected areas. Many of these areas may not be pristine habitat; some
areas are either inhabited by humans or used by local communities to
extract resources. However, there are conservation awareness programs
in place throughout the corridor, and the great green macaw is being
intensely managed and monitored in the San Juan-La Selva Biological
Corridor.
Ecuador
This species is categorized as critically endangered in Ecuador
(Monge et al. 2009, p. 256), primarily due to deforestation and hunting
pressures. In Ecuador, the only potentially population is believed to
exist in the Cerro Blanco Protected Forest, which is 6,070 ha (15,000
ac) in size. The Guayaquil subspecies of the great green macaw (Ara a.
guyaquilensis) is thought to be in imminent danger of extinction (Berg
2007, p. 1). In 2008, the National Preservation Strategy for the Great
Green Macaw in Ecuador was described at the Great Green Macaw
Population Viability Assessment and Habitat Conservation Workshop held
in Costa Rica; however, funding is still lacking for many of the
initiatives in Ecuador that have been prescribed as necessary for the
conservation of this species.
Honduras
The great green macaw is categorized as endangered in Honduras
(List of Wildlife Species of Special Concern, Resolution No. Gg-003-98
APVS). In 1990, the Government of Honduras prohibited the capture and
sale of wildlife, including the great green macaw in Honduras.
Currently, this species exists in the Rio Pl[aacute]tano Biosphere
Reserve (which consists of 800,000 ha or 1,976,843 ac). The official
designation of the Biosphere as a reserve is to protect and conserve
biodiversity; however, this designation has not halted deforestation
within the protected area (UNESCO 2011, p. 1; ParksWatch 2011; Wade
2007, p. 65). Additionally, as of 2009, there were 23 areas in Honduras
identified as Important Bird Areas (IBAs) (Devenish et al. 2009, p. 1)
that may provide additional protections to this species in part by
serving as ecotourism sites that can increase conservation efforts in
the areas. For additional information on IBAs, see the discussion above
for the military macaw.
Nicaragua
Nicaragua follows the IUCN categorization of endangered for this
species (Castellon 2008, pp. 13, 19; Lezama-L[oacute]pez 2006, p. 90).
The great green macaw exists in the Indio-Ma[iacute]z Biological
Reserve, which has had protected status since 1990, although threats to
the species still exist in this Reserve (Herrera 2004, pp. 5-6).
Nicaragua is also participating in the bi-national conservation
strategy for this species (Monge et al. 2009, pp. 11, 16).
Panama
There is little information available regarding the status of this
species in Panama (Monge et al. 2009, p. 67); however, Panama follows
the IUCN categorization for this species (Devenish et al. 2009, p.
294). The great green macaw is believed to be in Dari[eacute]n National
Park (Monge et al. 2009, p. 68). Panama's wildlife law of 1995, Law No.
24, establishes the standards for wildlife conservation.
NGO Involvement
There are many nongovernmental organization (NGO), private, and
government efforts to protect this species, although not all of the
projects and NGOs are identified in this document. NGOs have conducted
collaborative efforts, such as training workshops, that are community-
focused and aimed at the conservation of the habitat. In Nicaragua,
Fundaci[oacute]n Cocibolca is active in this species' conservation.
This NGO first signed an agreement with Nicaragua's Natural Resources
Ministry (MARENA) in 1996, at which time the conservation group was the
first NGO to have been granted responsibility to manage a national
protected area in Nicaragua (https://www.marena.gob.ni; accessed
November 9, 2011; https://www.planeta.com, accessed November 9, 2011).
The Nicaraguan conservation organization, Fundaci[oacute]n del Rio,
works in the buffer zone of the Indio-Ma[iacute]z Biological Reserve,
which borders the San Juan River (Villate 2008, p. 39). In 1999,
Fundaci[oacute]n del Rio began an environmental education program in
this buffer zone to promote awareness of the great green macaw and its
habitat. In another area, as a result of conservation efforts, the
local government of El Castillo declared this species the official
municipal bird, and the city established sanctions to those intending
to harm this species (Chassot et al. 2008, p. 23).
Since 2001, Fundaci[oacute]n del R[iacute]o and the Tropical
Science Center in Costa Rica have coordinated a binational campaign
focused on promoting the awareness of the ecology of the great green
macaw in the lowlands of the San Juan River area (Chassot et al. 2009,
p. 9). Between 2002 and 2005, at least 11 workshops on great green
macaw biology and preservation were held within communities of the
buffer zone of Indio-Maiz Biological Reserve in Costa Rica (Chassot et
al. 2006, p. 86). Some examples of projects initiated by NGOs include
installation of nest boxes to increase nest availability and community
heritage festivals that are focused on the great green macaw. Some NGOs
are providing training to local communities to monitor populations, and
some researchers are studying this species via satellite transmitters
to determine the species' home range and specific habitat used (Chosset
et al. 2004, p. 35). In Costa Rica and Nicaragua, 20 communities are
participating in monitoring and protection activities of the great
green macaw (Chosset and Arias 2010, p. 3). The primary objectives of
the campaign have been to improve awareness by conducting workshops on
the importance, threats, and conservation of the great green macaw and
its habitat; to strengthen natural resources management by
environmental authorities of both Nicaragua and Costa Rica, focusing on
the local and international biological corridors; and to organize joint
activities (Chassot et al. 2006, p. 83).
In Colombia, the NGO ProAves has made great progress in forming
partnerships at the local, regional, and international levels to carry
out bird conservation initiatives (Chassot et al. 2008, p. 23; Quevado-
Gill et al. 2006, p. 18). Additionally, reforestation efforts have
occurred (Monge et al. 2009, p. 263). These efforts have focused
primarily within the reserves of the Colombian Civil Society
Association Network (Quevado-Gill et al. 2006, p. 17). Conservation
efforts and these workshops have been important because they have
trained the community in sustainable development by linking local
agricultural activities to the protection of natural resources
(Quevado-Gill et al. 2006, p. 17).
Three NGOs are active in the conservation of this species in
Ecuador: Pro-Forest Foundation in Guayas
[[Page 60004]]
Province, Fundaci[oacute]n Natura, and the Jocotoco Foundation at the
Rio Canande Reserve in Esmeraldas Province. The Pro-Forest Foundation
(Fundaci[oacute]n ProBosque) was created in 1992, through a decree of
the Ecuadorian Ministry of Agriculture. Its mission is to protect areas
with an emphasis in reforestation, agroforestry, investigation,
environmental education, and ecotourism programs, all in order to
support the conservation of biodiversity.
In Panama, the Asociaci[oacute]n Nacional para la
Conservaci[oacute]n de la Naturaleza (ANCON) began conservation work in
1991. The project has jointly worked on conservation efforts with
Panama's Instituto Nacional de Recursos Naturales Renovables
(INRENARE). ANCON has worked on training park rangers, marking and
patrolling paths and park boundaries, acquiring property around parks
and tree nurseries, and improving agricultural techniques (TNC 2011, p.
2).
Additionally, members from several NGOs participated in the great
green macaw conservation workshop held in 2008. The purpose of the
workshop was to bring together experts, to determine the priorities for
the conservation of the species, and to develop a plan for its
conservation (Monge et al. 2009, entire). We acknowledge the
substantial effort under way by various NGOs in the range countries of
this species to protect it and its habitat. Despite many efforts in
place, the populations of the great green macaw continue to face many
threats to its habitat.
Evaluation of Threat Factors
Introduction
Section 4 of the ESA (16 U.S.C. 1533) and implementing regulations
(50 CFR 424) set forth procedures for adding species to, removing
species from, or reclassifying species on the Federal List of
Endangered and Threatened Wildlife and Plants. Under section 4(a)(1) of
the ESA, a species may be determined to be endangered or threatened
based on any of the following five factors:
A. The present or threatened destruction, modification, or
curtailment of its habitat or range;
B. Overutilization for commercial, recreational, scientific, or
educational purposes;
C. Disease or predation;
D. The inadequacy of existing regulatory mechanisms; and
E. Other natural or manmade factors affecting its continued
existence.
In making this finding, information pertaining to the great green
macaw in relation to the five factors in section 4(a)(1) of the ESA is
discussed below. In considering what factors might constitute threats
to a species, we must look beyond the exposure of the species to a
particular factor to evaluate whether the species may respond to that
factor in a way that causes actual impacts to the species. If there is
exposure to a factor and the species responds negatively, the factor
may be a threat, and, during the status review, we attempt to determine
how significant a threat it is. The identification of factors that
could impact a species negatively may not be sufficient to compel a
finding that the species warrants listing. The information must include
evidence sufficient to suggest that these factors, singly or in
combination, are operative threats that act on the species to the point
that the species may meet the definition of endangered or threatened
under the ESA.
This rule focuses primarily on where this species has been
documented, which is generally in parks and other areas with protected
status and the peripheral zones. In some cases, we will evaluate the
factor by country. In other cases, we may evaluate the factor by a
broader region or context, for example, if we do not have adequate
information specific to a particular country about this species. This
is because often threats are the same or very similar throughout the
species' range.
A. The Present or Threatened Destruction, Modification, or Curtailment
of Its Habitat or Range
Throughout the range of this species, the factors impacting the
great green macaw are generally very similar. The main factors
affecting this species are habitat loss and degradation, and poaching
(McGinley et al. 2009, p. 11; Berg et al. 2007; Chassot et al. 2006;
Quevado-Gill et al. 2006, p. 16; Guedes 2004, p. 280). Both Central and
South America continue to experience high levels of deforestation (FAO
2010, p. xvi). Habitat loss is primarily due to conversion of the
species' habitat (generally forests) to agriculture and other forms
that are not optimal for this species (Chosset and Arias 2010, p. 3;
Monge et al. 2009, entire).
Almendro habitat, this species' primary food and nesting source,
has declined significantly (Schmidt 2009, p. 16), particularly since
the 1980s. Almendro and other tree species used by the great green
macaw have been selectively cut down and removed from this species'
habitat. Selective logging is the practice of removing one or two
generally large, mature trees and leaving the rest. Throughout the
range of the great green macaw, its habitat has declined primarily due
to competition for resources and human encroachment (Guedes 2004, p.
279; Rodr[iacute]guez-Mahecha and Hern[aacute]ndez-Camacho 2002;
Chassot and Monge 2002 in Rothman 2008, p. 509). Its habitat has
continuously been clear-cut and converted to agriculture or human
establishments, which is discussed in more detail below.
Logging
Tree species used by macaws tend to be large, mature trees with
large nesting cavities. The practice of selective logging often targets
old, large trees that macaws depend upon for nesting. In selective
logging, the most valuable trees from a forest are commercially
extracted (Asner et al. 2005, p. 480; Johns 1988, p. 31), and the
forest is left to regenerate naturally or with some management until
being subsequently logged again. Johns (1988, p. 31), looking at a West
Malaysian dipterocarp forest, found that mechanized selective logging
in tropical rainforests, which usually removes a small percentage of
timber trees, causes severe incidental damage. He found that the
extraction of 3.3 percent of trees destroyed 50.9 percent of the
forest. Selective logging can cause widespread collateral damage to
remaining trees, subcanopy vegetation, and soil, and the practice
impacts hydrological processes, erosion, fire, carbon storage, and
plant and animal species (Chomitz et al. 2007, pp. 117, 119; Asner et
al. 2005, p. 480). Forests that were selectively logged 15 years prior
became an open forest with skeletons of incidentally killed trees,
serious gulley erosion, and vegetation on waterlogged sites that had
been compacted by heavy vehicles (Edwards 1993, p. 9). Additionally,
the availability of food sources for frugivores (fruit-eaters, such as
the great green macaw) is reduced because the trees that contain
nutritional sources are no longer there.
Selective logging is particularly devastating to the almendro tree,
which is slow growing and may take centuries to reach sufficient size
to harbor cavities (Schmidt 2009, p. 15), and which great green macaws
need for both food and shelter. The almendro tree's wood is of great
commercial value due to its strength and durability for flooring,
roofing, and irrigation systems (Madriz-Vargas 2004, p. 8). Concern for
this tree species was significant enough that the species was listed as
CITES Appendix III by both Costa Rica and Nicaragua. Listing species in
Appendix III enhances conservation measures enacted for the species by
regulating international trade in the species. In general, shipments
containing CITES-
[[Page 60005]]
listed species receive greater scrutiny from border officials in both
the exporting and importing countries. The elimination of almendro
trees is possibly the most severe threat for the species in its range
countries with the exception of Ecuador, where the decrease in
availability of other tree species used by the great green macaw is a
concern.
Although the nest cavities that the macaws prefer (deep and dry)
may take 10 to 20 years to form, the nests themselves can last for
several decades (Chun 2008, p. 101). Even in undisturbed forests,
suitable tree cavities are usually limited. As a result, each loss of a
nest site can represent the loss of potentially many future chicks that
could have been raised in each tree cavity.
Agriculture
Habitat degradation, particularly due to conversion of forest
habitat to agriculture or plantations, is a major factor affecting
great green macaws. The clearing of forests and buffer zones for the
development of plantations for bananas, oil palms, cacao, coffee,
soybeans, and rice destroys great green macaw nesting sites and exposes
chicks to poaching for the pet trade (Botero et al. 2011, p. 92; Monge
et al. 2009, pp. 26, 29, 43, 54; Waugh 1995, p. 2). By 2005, the
world's tropical forest biomes had decreased to less than 50 percent
tree cover (Donald et al. 2010, p. 26), in part due to the above
activities. Tropical forest fragmentation due to these activities
continues to be a concern. A discussion of habitat loss and degradation
for each country follows.
Colombia
Very little information is available about the great green macaw's
status in Colombia (Botero-Delgadillo and P[aacute]ez 2011, pp. 86, 90;
Monge et al. 2009; Jahn in litt. 2004). A large population is believed
to exist in Los Kat[iacute]os National Park, which borders the swampy
and sparsely populated Dari[eacute]n region in Panama; however, there
are no recent reported observations of the species in this area.
Population surveys need to be conducted (Botero-Delgadillo et al. 2011,
pp. 88, 90; Monge et al. 2009). At least 40 percent of the great green
macaw's original distribution area in northwestern Colombia was
deforested by 1997 (Etter 1998 in Jahn in litt. 2004). Threats to this
species in Colombia have been identified as: Agriculture (particularly
illegal coca cultivation), agroindustrial farms, large forest plantings
of exotic trees, wood extraction, development of infrastructure, and
hunting, capturing, and harvesting of this species (Botero-Delgadillo
and P[aacute]ez 2011, pp. 91-92). Threats specific to Los Kat[iacute]os
National Park are illegal deforestation and hunting (UNEP-WCMC 2009, p.
1). In 2009, the threats in this park were so severe that the park was
added to UNESCO's List of World Heritage Sites in Danger (https://whc.unesco.org/en/list/711, accessed January 17, 2012).
Deforestation
Colombia has experienced extensive deforestation in the last half
of the 20th century as a result of habitat conversion for human
settlements, road building, agriculture, and timber extraction (FAO
2010, p. 233; Armenteras et al. 2006, p. 354). A 23-year study,
conducted from 1973 to 1996, found that these activities reduced the
amount of primary forest cover in Colombia by approximately 3,605 ha
(8,908 ac) annually, representing a nearly one-third total loss of
primary forest habitat (Vi[ntilde]a et al. 2004, pp. 123-124). More
than 70 percent of rural land of Colombia located in former forestlands
is now devoted to cattle grazing (Etter and McAlpine 2007, pp. 89-92).
Beginning in the 1980s, habitat loss increased dramatically as a result
of influxes of people settling in formerly pristine areas (Perz et al.
2005, pp. 26-28; Vi[ntilde]a et al. 2004, p. 124). More recent studies
indicate that the rate of habitat destruction is accelerating (FAO
2010, p. xvi). Between the years 1990 and 2005, Colombia lost
approximately 52,800 ha (130,471 ac) of primary forest annually (Butler
2006a, pp. 1-3).
Primary forest habitats such as those used by the great green macaw
throughout Colombia have undergone extensive deforestation. Vi[ntilde]a
et al. (2004, pp. 123-124) used satellite imagery to analyze
deforestation rates and patterns along the Colombian-Ecuadorian border
(in the Departments of Putumayo and Sucumbios, respectively) and found
that between 1973 and 1996, a total of 829 km\2\ (320 mi\2\) of
tropical forests within the study area were converted to other uses.
This corresponds to a nearly one-third total loss of primary forest
habitat, or a nearly 2 percent mean annual rate of deforestation within
the study area. Habitat loss and degradation, including conversion of
this species' habitat to other forms of use such as agriculture,
plantations, or harvesting of this species' plant food sources,
continue to occur and affect the quality of this species' habitat.
In addition to the direct detrimental effect of habitat loss, there
are several indirect effects of habitat disturbance and fragmentation,
such as road building (Brooks and Strahl 2000, p. 10). Roads increase
human access into habitat, facilitating further exploitation, erosion,
and habitat destruction (Chomitz et al. 2007, p. 88; Hunter 1996, pp.
158-159). Research has documented that road building and other
infrastructure developments in areas that were previously remote
forested areas have increased accessibility and facilitated further
habitat destruction and human settlement (Etter et al. 2006, p. 1;
[Aacute]lvarez 2005, p. 2,042; C[aacute]rdenas and Rodr[iacute]guez-
Becerra 2004, pp. 125-130; Vi[ntilde]a et al. 2004, pp. 118-119; Hunter
1996, pp. 158-159). A study conducted on the effects of habitat
fragmentation on Andean birds within western Colombia determined that
31 percent of the historical bird populations in western Colombia had
become extinct or locally extirpated by 1990, primarily as a result of
habitat fragmentation from deforestation and human encroachment (Kattan
and [Aacute]lvarez-Lopez 1996, p. 5; Kattan et al. 1994, p. 141).
Greater exposure of soil to direct sunlight leads to factors such as
drier soils and also creates a different growing environment. For
example, the creation of roads changes the habitat by altering the
distance of nesting and feeding habitat to the forest ``edge,''
increasing the amount of light exposure, and creating stress on
(breeding) individuals in part due to noise and visual stimuli
(Ben[iacute]tez-L[oacute]pez et al. 2010, p. 1,308).
Coca Cultivation
Ongoing coca cultivation has had a significant impact on forest
cover in Colombia (Armenteras et al. 2006, p. 355; Fjelds[aring] et al.
2005, p. 205; Page 2003, p. 2; [Aacute]lvarez 2002, pp. 1,088-1,093).
Colombia is one of the leading producers of coca, the plant species
that provides the main ingredient of cocaine. Between 1998 and 2002,
cultivation of illicit crops increased by 21 percent each year, with a
parallel increase in deforestation of formerly pristine areas of
approximately 60 percent ([Aacute]lvarez 2002, pp. 1,088-1,093). Much
of Colombia's coca is grown by farmers because it generates more income
than any other crop (Butler 2006, pp. 1-2). Illegal drug crops are
cultivated within the great green macaw's range (BLI 2014b, p. 4).
Large-scale coca production has moved into the extensive rainforests of
the Choc[oacute] state, which is considered to be a biodiversity
hotspot in northwest Colombia and in the range of the great green
macaw.
A 1990 United Nations study estimated that coca growers can make
about $4,000 U.S. dollars per hectare (Tammen 1991, p. 12 in Page 2003,
pp.
[[Page 60006]]
15-16). A farmer can only earn about $600 per hectare growing an
alternative crop such as coffee, which is the most often cited
potential substitute crop for coca (Page 2003, pp. 15-16). Page (2003,
pp. 15-16) notes that production of coffee and tea requires 3 to 4
years from planting to first harvest and then can only be harvested
once per year, while coca can be harvested 8 months after it is planted
and can be harvested every 90 days thereafter. The coca bushes
themselves do not require much care and can be cultivated on plots of
land that are much smaller than those required for crops other than
coca (Tammen 1991, p. 6 in Page 2003, p. 16). Unfortunately, not only
do coca crops displace native habitat and species assemblages that are
important for the great green macaw, but they also deplete the soil of
nutrients, which hampers regeneration following abandonment of fields
(Van Schoik and Schulberg 1993, p. 21).
Drug eradication efforts in Colombia have further degraded and
destroyed primary forest habitat by using nonspecific aerial herbicides
to destroy illegal crops (BLI 2007d, p. 3; [Aacute]lvarez 2005, p.
2,042; C[aacute]rdenas and Rodr[iacute]guez Becerra 2004, p. 355;
Oldham and Massey 2002, pp. 9-12). For example, in 2006, eradication
efforts were undertaken on over 2,130 km\2\ (822 mi\2\) of land, which
included spraying of 1,720 km\2\ (664 mi\2\) and manual eradication on
the remaining land. These eradication efforts occurred over an area 2.7
times greater than the net cultivation area (UNODC et al. 2007, p. 8).
Herbicide spraying has introduced harmful chemicals into great green
macaw habitat and has led to further destruction of the habitat by
forcing growers to move to new, previously untouched forested areas
([Aacute]lvarez 2007, pp. 133-143; BLI 2007d, p. 3; [Aacute]lvarez
2005, p. 2042; C[aacute]rdenas and Becerra 2004, p. 355; Oldham and
Massey 2002, pp. 9-12; [Aacute]lvarez 2002, pp. 1,088-1,093).
The ecological impacts of coca production are significant. Farmers
clear forest to plant coca seedlings. Not only does each hectare of
crop production result in the clearing of roughly 1.6 ha (4 ac) of
forest, this practice also results in secondary effects such as the
pollution of land and local waterways with the chemicals used to
process coca leaves, including kerosene, sulfuric acid, acetone, and
carbide (Butler 2006, pp. 1-2).
Costa Rica
Most of the research on this species has been conducted in Costa
Rica, where a very small population of this species remains. Despite
Costa Rica's progress in conservation of this species, the historical
breeding area for this species in Costa Rica has been reduced by 90
percent (Villate et al. 2008, p. 19; Chosset et al. 2004, p. 38). In
2004, approximately 30 reproductive pairs remained in the wild in Costa
Rica (Madriz-Vargas 2004, p. 4). Up until the 1960s, Costa Rica's human
population was growing by approximately 4 percent annually (World Bank
2011, unpaginated; Chun 2008, p. 6). Logging in the 1960s and 1970s
decimated this species' habitat (Hardman 2011, p. 8). In the 1980s, the
area near Puerto Viejo de Sarapiqui experienced severe deforestation
and conversion to banana and pineapple plantations. By 1996, 52,000 ha
(128,495 ac) of lowland forest had been converted to banana plantations
(Brewster 2009, p. 8). The loss of forested area in the north has
primarily been due to the production of livestock, forestry products,
sugar cane, and (in more recent years) pineapple (Villate et al. 2008,
p. 15).
In the mid-1980s, policies changed from granting incentives for
livestock and cattle ranching to reforestation for forest management.
However, these incentives led initially to the clearing of forests for
conversion to exotic species plantations. As a result, forestry in
Costa Rica (and Panama) has been dominated by the use of exotic species
such as Tectona grandis (teak) or Gmelina arborea (melina) (Schmidt
2009, p. 10). This trend changed in 1986 with the Forestry Act 7472. In
the 1990s, the government began to create incentives for small farm
owners to establish and maintain native tree species plantations
(Piotto et al. 2003, p. 427). By 1992, a project was implemented to
improve the use of forested areas; however, it estimated that by this
time only 5 percent of original forest area remained intact (Chassot et
al. 2001 in Villate et al. 2008, p. 15). Reforestation projects began
initially through an agreement between Costa Rica and Germany. The
program was implemented by the Agribusiness Association and Forestry
Producers (APAIFO) and the Cooperation for Forestry Development San
Carlos (CODEFORSA).
In Costa Rica's border zone with Nicaragua, Landsat TM satellite
images from 1987, 1998, and 2005 showed a fragmented landscape with
remnants of natural ecosystems, which has implications for the
conservation of this species. The images identified several classes of
cover and land use (natural forest, secondary forest, water,
agriculture and pasture, banana and pineapple plantations, and bare
ground) (Chassot et al. 2009, pp. 8-9). These researchers noted that
the annual rate of deforestation was 0.88 percent for the 1987-1998
period, and 0.73 percent for the 1998-2005 period, taking into
consideration recovery of secondary forest. The researchers also noted
that, in the area studied, deforestation rates were higher than
national averages for the same time span (Chassot et al. 2009, p. 9).
In the 1990s, plans to form the San Juan-La Selva Biological
Corridor began in response to the significant decrease in habitat
available to the great green macaw and its decline in population
numbers. In 1993 and 1994, about 1,000 km\2\ (386 mi\2\) were
identified as important nesting areas for this species in Costa Rica.
In 2002, the San Juan-La Selva Biological Corridor, an area of 60,000
hectares (148,263 ac), was established to protect the nesting sites and
migration flyway of the great green macaw in Costa Rica, up to the
Nicaragua border (Guedes 2004, p. 280). Although this corridor is in
place, recent reports indicate that habitat degradation and other
factors continue to affect the great green macaw (Monge et al. 2009, p.
121).
Costa Rica was the only country in Central America that had a
positive overall increase in forest area during the period 2000-2005
(FAO 2010, p. 19; FAO 2007). Intense efforts are under way in Costa
Rica to conserve and recover this species, in part by addressing
habitat degradation. In some areas, the commercial use of the almendro
tree is now being replaced by synthetic material due to conservation
efforts focused on the great green macaw. In some areas, landowners are
being paid to protect and ``adopt'' almendro trees, and several
ecotourism projects have developed using these trees and the macaws as
part of the ecotourism attraction. As of 2009, 12 nesting trees had
protection agreements (Brewster 2009, p. 10). Still, habitat
degradation continues to impact the great green macaw (Villate et al.
2008, p. 14), and even trees that are designated as protected are
either cut down or targeted for poaching (Chun 2008). Logging still
occurs in the remnant forests of both the northern zone of Costa Rica
and southeast Nicaragua (Chassot and Arias 2011, p. 1; Monge et al.
2009, pp. 128-129). Logging, while it may be illegal, has also been
documented in the buffer zone of the Indio-Ma[iacute]z Biological
Reserve (Monge et al. 2006, p. 10). The buffer zone is within the
breeding range of the great green macaw and likely affects the species'
viability. Additionally, both primary and regrowth forest in the San
Juan-La Selva Biological Corridor
[[Page 60007]]
continue to be threatened by timber extraction and agricultural
expansion (Chassot and Arias 2011, p. 1; Monge et al. 2009, pp. 128-
129).
Mining
Gold mining may also affect conservation efforts for the great
green macaw in Costa Rica. In 2001, the Ministerio del Medio Ambiente y
Energ[iacute]a (MINAE) granted a mining concession (Resolution R-578-
2001-MINAE) in San Carlos to clear nearly 202 ha (500 ac) of old-growth
rainforest for a project (Villate 2009, p. 57; https://www.infinito.co.cr and https://www.nacla.org, both accessed November 15,
2011). The Crucitas mining project is located in the Northwest Corridor
of San Juan-La Selva, a few miles from the San Juan River (which
separates Costa Rica from Nicaragua). The Crucitas area is part of a
major zone for bird conservation initiatives, partly implemented by
BLI, that includes both the Water and Peace Biosphere Reserve and the
San Juan-La Selva Biological Corridor (Chassot et al. 2009, p. 9),
including the El Castillo extension. It is reported that 72 percent of
the area that had been proposed for implementation of the project is
forested and contains almendro tree (and consequently great green
macaw) habitat. The company proposed to clearcut the area in order to
establish the open pit mine.
In adjacent Nicaragua, the area of influence of the mining project
is also part of the buffer zone of the two reserves: San Juan River
Biosphere Reserve and the Indio-Ma[iacute]z Biological Reserve. These
areas contain features of endemism and species compositions that are
unique (Sistema Nacional de [Aacute]reas de Conservaci[oacute]n (SINAC)
2007 in Villate et al. 2008, p. 58). Although Crucitas is not part of
the current nesting area of the great green macaw, it is only about 10
km (3 mi) southeast of the historical distribution of the species. The
mining activities are likely to affect the current population of the
great green macaw by impacting its habitat as well as ongoing
conservation efforts. The project lies within a geographical area that
is of critical importance to the conservation of this species.
Additionally, the removal of more primary forest cover would further
reduce the ability to maintain connectivity along the San Juan-La Selva
Biological Corridor, which continues to be subjected to fragmentation
(Villate 2008, p. 58). As of November 2010, a court ruled that the
open-pit gold mine was improperly permitted (https://centralamericadata.biz/en/article/home/Crucitas_Mining_Concession_Cancellation_Confirmed, accessed January 12,
2012). However, prior to the court ruling, 121 ha (300 ac) of primary
forest had already been cleared (https://www.santuariolapas.com/profile_003.html, accessed December 14, 2011). The ultimate impacts and
outcome of the mining project are unclear; however, the species is and
will continue to be impacted by pressures for resources that affect its
habitat.
Ecuador
Although the population of great green macaw is reported to be
stable and slowly increasing in the Cerro Blanco Protected Forest, it
is an extremely small population (Monge et al. 2009, p. 256). There are
likely fewer than 100 individuals remaining in Ecuador. In this part of
its range, three tree species are noted as crucial for the survival of
the species: Lecythis ampla (salero) and Cynometra bauhiniaefolia
(cocobolo) as primary food sources, and Cavanillesia platanifolia
(pigio) as a nest tree (Horstman 2011 pers. comm. 2011). Logging,
poaching, and illegal land settlements continue to occur in the great
green macaw's range and are threats to the population in Ecuador,
particularly in the Cerro Blanco Protected Forest (https://www.worldlandtrust-us.org, unpaginated; World Wildlife Fund 2011, p. 5;
Horstman 2011, p. 12). Between 1960 and 1980, the human population in
Ecuador grew from 4 to 10.2 million, which resulted in more than 90
percent of Pacific lowland and foothill forest below 900 m (2,953 ft)
being converted to agriculture (Dodson and Gentry 1991, p. 279). Much
of the species' habitat was converted to plantations of bananas, oil
palms, cacao, coffee, soybeans, and rice (ELAW 2005, p. 1; Dodson and
Gentry 1991, p. 279).
In 2002, the Government of Ecuador authorized the conversion of
50,000 ha (123,553 ac) of tropical forest in the Choco region of
western Ecuador into oil palm plantations (ELAW 2005, pp. 1-2). As of
2005, 374 ha (924 ac) of native forests were being cut daily (Horstman
2005, p. 8). Clearing forests for this monoculture crop has threatened
thousands of endemic species and introduced dangerous pesticides to
local ecosystems (Alb[aacute]n and C[aacute]rdenas 2007, p. 43). For
example, in Esmeraldas Province, pesticides are used intensively in a
36,000-ha (88,958-ac) area of oil palm plantations (ELAW 2005, pp. 1-
2). Local villages cite problems from the pesticides and effluents from
the processing plants.
The Food and Agriculture Organization of the United Nations (FAO)
reported in 2010 that, in Ecuador, ``planted forests are predominantly
composed of introduced species,'' such as rubber plantations and other
nonnative species (FAO 2010, p. 93), which do not provide appropriate
habitat and nutritional needs for the great green macaw. Despite these
activities, due to the efforts of the ProForest Foundation--the NGO in
charge of the reserve--the population in the Cerro Blanco forest
preserve is reported to be stable (Horstman 2011, p. 17). The Cerro
Blanco forest preserve is a small area that is being managed
particularly for this species. It is jointly owned by the ProForest
Foundation and a cement company, Holcim, as mitigation for its nearby
limestone quarries. Reserve managers are converting former cattle
pasture to native tree farms, which they use to help restore dry
tropical forest in other locations, including a corridor to nearby
patches of forested areas (Horstman 2009 pers. comm.). Despite the
conservation efforts in place, logging, poaching, and illegal land
settlement continue to affect the population in the Cerro Blanco
Protected Forest (Horstman 2011, p. 17; Fundacion Pro-Bosque, undated,
p. 3). A conservation strategy for this species recommends that a ban
be instituted on the cutting and commercialization of the three tree
species described above that were noted as crucial for the great green
macaw's survival (Monge et al. 2009, pp. 256-258). However,
deforestation, encroachment, and habitat degradation activities such as
these continue (Horstman 2011, p. 17).
Another threat to the macaw's population in this reserve is the
rapid expansion of the city of Guayaquil. Squatter settlements develop
on the city's outskirts and encroach the forest (Fundacion ProBosque
undated, p. 3). Illegal settlements are a problem, and squatter
communities have attempted to take over property within Cerro Blanco.
The local NGO conducts educational awareness programs to mitigate these
activities. An example of awareness campaign activities is educating
the local communities about the effect on their water supply when they
destroy forested areas (Horstman pers. comm. in Hardman 2011, p. 13).
However, pressures to this species' habitat continue to impact the
species.
Honduras
In Honduras, threats have included illegal trafficking of this
species and deforestation due to agriculture, cattle grazing, and
logging (Devenish et al. 2009, p. 256). The threat of deforestation is
particularly important because a
[[Page 60008]]
recent study found that 87 percent of Honduras is only suitable for
forest (Larios and Coronado 2006, p. 13) due to its generally
mountainous terrain. There is very little information available on the
status of this species in Honduras, particularly scientific literature
(Monge et al. 2009, p. 122). Only six papers on avian diversity and
avian population surveys in Honduran forests were published between
1968 and 2004 (Anderson et al. 2004, p. 456). However, we do know that
the threats in Honduras are similar to those in other countries within
the range of this species (McCann et al. 2003, pp. 321-322), and the
most significant threat is deforestation. In 2008, the Departamento de
[Aacute]reas Protegidas y de Vida Silvestre (DAPVS) in Honduras
estimated that 80,000 ha (197,684 ac) of natural areas were being
destroyed annually (DAPVS 2008 in Devenish et al., 2009 p. 256).
The great green macaw is believed to exist in the R[iacute]o
Pl[aacute]tano Biosphere Reserve within the watershed of the
Pl[aacute]tano River (Monge et al. 2009, p. 8). The area is also known
as the ``Mosquitia Hondure[ntilde]a,'' which is 500,000 ha (1,235,527
ac) in size. The reserve serves as protection to the 100-km (62-mi)
long Pl[aacute]tano River watershed in addition to protecting parts of
the Paulaya, Guampu, and Sicre rivers (Devenish 2009, p. 256). Several
indigenous tribes such as the Miskito, Tawahka, Pech, Gar[iacute]funas,
and ``Mestizos'' use this area for their traditional livelihoods.
Although this reserve was designated as a World Heritage Site,
pressures to the reserve area for its resources continue (TNC 2011,
unpaginated). In 2011, the R[iacute]o Pl[aacute]tano Biosphere Reserve
was added to the list of World Heritage Sites in danger due to
encroachment (UNEP-WCMC 2011, p. 1).
In the R[iacute]o Pl[aacute]tano Biosphere Reserve of Honduras, the
unregulated extraction of timber and mass production of bananas has
caused an alarming decline of great green macaw populations (Devenish
et al. 2009, p. 256). The deforestation in Honduras is occurring as a
result of an increase in the human population, which requires clearing
areas for home development as well as wood products (Devenish et al.
2009, p. 256). The annual human population growth rate as of 2011 was
estimated to be 1.09 percent (U.S. Department of State 2011,
unpaginated). Palacios and Brus Laguna, towns on the coast
approximately 5 km (3.1 mi) from the park on either side of the
reserve, are likely contributing to the pressures such as agriculture
and logging that are occurring illegally in the reserve.
Nicaragua
In Nicaragua, great green macaws face reductions in populations due
to illegal extraction of timber and agricultural expansion (McGinley et
al. 2009, pp. 13, 33, 35; Jeffrey 2001, pp. 1-5). Overall, there is a
lack of information about the status of the great green macaw
population and its habitat in Nicaragua (Monge et al. 2010; Monge et
al. 2009, pp. 52-53). However, a population of the great green macaw is
known to occur in the Indio-Ma[iacute]z Biological Reserve, located in
Nicaragua just across the San Juan River at the northeastern border of
Costa Rica (Monge et al. 2009, p. 51), where suitable habitat for this
species remains. This reserve, which is believed to be one of the few
strongholds for the great green macaw, is nearly 264,000 ha (652,358
ac) in size. It is likely that the Indio-Ma[iacute]z Biological Reserve
contains extensive forest areas with high densities of almendro trees
(Chun 2008, p. 94) and, therefore, is critical to this species'
survival. Chun suggests that many areas in Nicaragua may exceed the
minimum great green macaw nesting requirement of 0.20 trees per hectare
within the breeding territory. Although the Indio-Ma[iacute]z
Biological Reserve is considered one of Nicaragua's best preserved
forested areas and has limited access, its buffer zone has recently
been under assault from activities such as loggers in search of lumber
and illegal farming of Elaeis guineensis (African palm) trees for
biofuel (Chosset and Arias 2010, p. 3; Ravnborg et al. 2006, p. 2). As
resources become scarcer in the buffer zones, illegal activities push
farther into the lesser disturbed and lesser accessible areas. Despite
the existence of this protected area, deforestation continues to occur.
Deforestation is one of the major threats to biodiversity in this
region; one steadily increasing form is the conversion of forest into
agricultural or pastural lands (Chassot et al. 2006, p. 84). In
Nicaragua, between 1990 and 2005, 1.35 million ha (3.34 million ac) of
forested areas were converted to agriculture or were deforested due to
other reasons such as logging (FAO 2010, p. 232; FAO 2007). Much of
Nicaragua has protected status. In 2005, approximately 36 percent of
Nicaragua's forested area was designated as protected or in some form
of conservation status (FAO 2007). Additionally, in 2007, there were 72
protected areas in Nicaragua's National System of Protected Areas
(Castellon 2008, p. 19). However, 88 percent of Nicaragua's area
designated as forest is privately owned (FAO 2010, p. 238) and,
therefore, is not protected. Additionally, much of the logging that
occurs is illegal and is not monitored (Pellegrini 2011, p. 21;
Richards et al. 2003, p. 283).
As an example, the Bosawas Reserve is one of the areas believed to
contain great green macaws as well as suitable habitat for a viable
population. It was designated a reserve in 1979, in response to the
advance of the agricultural frontier (Cu[eacute]llar and Kandel 2005,
p. 9). However, during the 1980s, the area was not managed; it was the
battleground for the armed conflict between the Sandinistas and the
Contras (Cu[eacute]llar and Susan Kandel 2005, p. 9). In October 1991,
Bosawas was declared a National Natural Resource Reserve through
Executive Decree No. 44-91. Despite its designation as a protected
area, encroachment and habitat degradation still occur (McCann et al.
2003, p. 322). In Bosawas, indigenous tribal communities have rights to
use the forests under the Autonomy Statute of 1987 (Cu[eacute]llar and
Kandel 2005, p. 11). As of 1998, the indigenous population was
approximately 9,200 in or near the Bosawas reserve (Stocks et al. 2007,
p. 1,497). In 2005, the Nicaraguan Government granted land titles to 86
indigenous Miskitu and Mayangna groups in Bosawas and contiguous
indigenous areas (Stocks et al. 2007, p. 497). Generally, these
indigenous communities manage the forests well and want to maintain
their traditional way of life. However, ``mestizo'' communities were
encouraged to settle in the area that is now the reserve's buffer zone
during the period when lands were being converted to plantations. Both
the mestizo and indigenous communities depend on access to land to
ensure their livelihoods. However, the mestizo communities convert
primary forest to agricultural or livestock uses (Cu[eacute]llar and
Kandel 2005, p. 13), while the indigenous communities have less impact
on the ecosystem. Land rights disputes are common in these areas, and
land use rights are often unclear. The Government of Nicaragua is
attempting to manage these issues (Pellegrini 2011, p. 21), but
conflict and practices that degrade the great green macaw's habitat
persist both in the Bosawas Reserve and in other areas within the range
of the species.
One of the factors contributing to deforestation in this area is a
high rate of poverty (Pacheco et al. 2011, p. 4). Nicaragua is the
poorest country in Central America (CIA World Factbook 2014). In part,
due to the high rate of poverty, the great green macaw continues to
face threats to its habitat.
[[Page 60009]]
Communities living within the range of the great green macaw practice
unsustainable activities, such as conversion of habitat to agriculture
or logging, which contribute to deforestation of the species' remaining
habitat in Nicaragua (McGinley 2009, p. 36; Castellon 2008, pp. 21, 30;
Richards et al. 2003, p. 282). Much of the Indio-Ma[iacute]z Biological
Reserve is described as being intact and unlogged (Chun 2008, p. 116).
Despite this, some loggers cross the border into Nicaragua to harvest
the almendro tree (Schmidt 2009, p. 16; Chassot et al. 2006, p. 84).
Anecdotal reports indicate that Costa Rican loggers pay Nicaraguan
farmers about $15 for each almendro tree, bring the logs to Costa Rica,
and sell them for about $1,450 in Costa Rica (Arias 2002, p. 4).
Because incomes in the Bosawas region of Nicaragua were found to
average under $800 per family per year (Stocks et al. 2007, p. 1,498),
the almendro trees are quite valuable. Consequently, a binational
biological corridor between Nicaragua and Costa Rica was proposed in an
attempt to prevent the extinction of the almendro tree (Chassot et al.
2006, p. 84). Although this corridor exists and efforts are in place
(refer to discussion under Factor D, below) to mitigate border issues
(Hernandez et al., undated, pp. 1-14) in this region, habitat
degradation continues.
Panama
In Panama, this species is believed to primarily exist in the
Dari[eacute]n region, which borders northern Colombia (Angeher 2004, in
litt.). Deforestation was estimated to exceed 30 percent of the
species' original range in Panama (Angehr 2004, in litt.). Although
there is limited information available on the threats affecting great
green macaw populations in Panama, deforestation is known to occur
within this species' range (Monge et al. 2009, p. 68; Angehr 2004, in
litt.). Conflict regarding land rights of indigenous communities has
become one of the most critical issues in the Dari[eacute]n region. The
most significant threats to tropical forests in Panama overall include
road construction and road improvement, especially in the Dari[eacute]n
region, and agricultural expansion, particularly in the Dari[eacute]n
and Bocas del Toro regions, which results in increased access to
forests (Parker et al. 2004, p. V-2). Roads have been found to be one
of the leading causes of global biodiversity loss (Ben[iacute]tez-
L[oacute]pez et al. 2010, p. 1,307). The construction of the Pan-
American Highway and other roads are affecting the Dari[eacute]n forest
area (TNC 2011, p. 1). When roads are constructed, they increase access
to previously inaccessible areas. This leads to more pressures on the
forested areas, such as conversion to agriculture, competition for
resources (such as the extraction of plant species that may be consumed
by the great green macaw), and more logging.
A 2006 report indicated that the advance of the agricultural
frontier and ``spontaneous colonization'' occurring at a rate of 50,000
to 80,000 ha (123,500 to 197,700 ac) per year is rapidly shrinking
Panama's forests and protected areas (McMahon et al. 2006, p. 8). Prior
to its formal designation in 1990, La Amistad National Park, which
spans the border between Costa Rica and Panama, experienced impacts
from cattle ranching, timber extraction, burning, and illegal
settlements (UNEP-WCMC 2011, p. 7). Trails, human encroachment, roads,
grazing, and hunting continue in this area and affect this species'
habitat (TNC 2012, unpaginated; UNEP-WCMC 2011, p. 7). Soil and water
resources have been depleted due to traditional agricultural practices
and inadequate conservation measures. Indigenous production systems,
with their low-intensity land use, long rotation periods, and plentiful
forests for hunting and gathering, are increasingly becoming
unsustainable due to economic pressures. These indigenous production
systems are being replaced by farming systems that emphasize
monoculture without rotation, which leads to depleted soils and
encourages greater expansion of the agricultural frontier. These
threats are exacerbated by rural poverty that drives populations in
search of areas with high levels of globally significant biodiversity
(Pacheco et al. 2011, pp. 4, 18). As a result of competition for
resources, many farmers and indigenous people have emigrated to the
Dari[eacute]n and Bocas del Toro provinces, where the great green macaw
is believed to exist in larger numbers than in other parts of the
species' range. Unsustainable land practices, the lack of capacity by
both public and private stakeholders to encourage sustainable land use,
infrastructure development, and the lack of management plans further
exacerbate the degradation of this species' habitat.
Dari[eacute]n forests are under pressure from the expanding
agricultural frontier and related colonization (TNC 2011, p. 1; McMahon
2006, p. 8). The region's human population is growing at a rate of
about 5 percent a year. Loss of forest cover is often linked to
agricultural expansion, which often follows new or improved roads, and
which results in increased access to forests. Slash-and-burn
agriculture has resulted in huge tracts of deforested land. Other
factors that affect the stability of great green macaw populations
include the National Authority for the Environment's (ANAM) inability
to fund programs for protected areas and buffer zones, and the
extraction of other minerals and building materials, whether legal or
illegal (Angehr et al. 2009, p. 291). Logging and mining is legally
restricted in the area; however, logging still occurs outside the
Dari[eacute]n reserve, and the practice encroaches on remaining forest
cover in the buffer zone. Problems in or adjacent to protected areas
include illegal clearing for development, agriculture, and cattle
grazing; road construction; and extraction of minerals or construction
materials (Devenish et al. 2009b, p. 291).
The presence of gold mines in the Dari[eacute]n Region,
particularly the Cerro Pirre area, was also indicated to be a threat to
the species. Significant mining activities in this area were conducted
prior to the 18th century. The clearing of forests to create roads for
mining facilitates the transport of materials and personnel in and out
of the mining zones (Robbins et al. 1985, pp. 200, 202). Roads
exacerbate deforestation practices such as logging and conversion to
agriculture or other land uses, as well as colonization. This area is
now an ecotourism site; as of 1985, there is now second-growth forest
recovery from the gold mines that had been abandoned during the 18th
century. It does not appear that mining in this area still occurs, and,
therefore, mining is not currently impacting the species.
Summary of Factor A
The global population of great green macaws is decreasing due to
the loss of much of the older forested areas, thus reducing high-
quality habitat for this species, and relegating it to relatively small
and isolated patches throughout its range; however, suitable habitat
remains in some protected areas in Central and South America. Habitat
degradation poses a significant threat throughout the range of the
great green macaw, which is especially vulnerable to the effects of
isolation and fragmentation because it tends to mate for life, it has a
small clutch size and specialized habitat requirements, and its
populations are small and decreasing.
The great green macaw is naturally associated with unfragmented,
mature, forested landscapes, and is considered a habitat specialist
that selects areas of contiguous mature forest in Central America and
parts of northern South America (Monge et al. 2009; Madriz-Vargas 2004,
p. 7). This species requires
[[Page 60010]]
large areas for its feeding requirements and is not well adapted to
fragmented landscapes. Deforestation results in fragmented forests with
high ratios of edge to forested area, and the original biodiversity
upon which this species depends is lost. Greater exposure of soil to
direct sunlight leads to factors such as drier soils and also creates
an altered growing environment. Because there are fewer remaining
older, complex forest stands providing adequate habitat for breeding,
feeding, and nesting, great green macaw populations are in decline. The
great green macaw is threatened by the impacts of both past and current
habitat loss, including ongoing habitat modification that results in
poor quality and insufficient forest habitats, habitat fragmentation,
and isolation of small populations. The ability of the great green
macaw to repopulate an isolated patch of suitable habitat following
decline or extirpation is particularly unlikely due to the species'
large home range requirements, and this is exacerbated by its small
overall population size and the large distances between the remaining
primary forest fragments. Despite the existence of the binational
corridor in Nicaragua and Costa Rica and a multitude of conservation
efforts, we find that the present or threatened destruction,
modification, or curtailment of habitat is a threat to the great green
macaw now and in the future.
B. Overutilization for Commercial, Recreational, Scientific, or
Educational Purposes
Because this species has an extremely small and fragmented
population, poaching, while apparently uncommon, remains a concern
(Botero-Delgadillo and P[aacute]ez 2011, p. 13; Monge et al. 2009, pp.
26, 40, 106). Removal of this species from the wild has a significant
detrimental effect to this species because this species tends to mate
for life and only produces 1 or 2 eggs annually. The species has been
heavily poached in the wild historically and is still trafficked for
the pet trade in Honduras and Nicaragua (Anderson 2004, p. 453; https://www.lafeberconservationwildlife.com/?p=1714, accessed December 14,
2011). Although there are no known current reports of poaching in all
parts of its range, poaching was raised as a concern at the 2008
workshop held in Costa Rica on this species (Monge et al. 2009,
various). After regulatory mechanisms such as CITES and the WBCA were
put into place, particularly since 1992 when the WBCA went into effect,
much of the legal trade in the great green macaw declined (see
discussion of military macaw for more information about WBCA) (UNEP-
WCMC CITES trade database, accessed September 6, 2011). The great green
macaw was listed in CITES Appendix II, effective June 6, 1981, and was
transferred to Appendix I, effective August 1, 1985. Most of the
international trade in great green macaw specimens consists of live
birds.
Data obtained from the United Nations Environment Programme-World
Conservation Monitoring Center (UNEP-WCMC) CITES Trade Database show
that, during the 4 years the great green macaw was listed in Appendix
II, 26 live great green macaws (and an additional eight feathers) were
reported to UNEP-WCMC as (gross) exports. In analyzing the data, it
appears that several records may be overcounts due to slight
differences in the manner in which the importing and exporting
countries reported their trade. It is likely that the actual number of
live great green macaws in international trade during this period was
22. All of the live birds were reported with the source ``unknown.''
Exports from range countries included six live birds from Panama and
five live birds from Nicaragua (UNEP-WCMC 2011).
During the more than 28 years following the transfer of the species
to Appendix I (August 1985 through December 2013, the last year for
which complete data were available at the time the following numbers
were compiled), the UNEP-WCMC database shows 920 live birds in
international trade. However, because it is some over-counts likely
occurred in the database due to slight differences in the manner in
which the importing and exporting countries reported their trade, it is
likely that the actual number of live great green macaws in
international trade during this period was 831 (U.S. CITES Management
Authority 2015). Of these, 776 were reported to be captive-bred or
captive-born, 5 were reported as wild, and 15 were reported as ``pre-
Convention.'' The source of the remaining live birds is unknown.
Exports of live birds from range countries included 17 from Costa Rica,
10 from Ecuador, 12 from Nicaragua, and 6 from Panama. Note also that
some of these birds may be personal pets that are counted more than
once.
Historically, the pressure to remove this species from the wild for
the pet trade has contributed significantly to the decline in
population numbers for this species. Poaching continues to occur in
this species' range, particularly in Nicaragua (Castellon 2008, pp. 20,
25; Kennedy 2007, pp. 1-2; BLI 2007, p. 1). The majority of information
available for Central America regarding poaching and the sale of parrot
species were focused in Nicaragua (Herrera-Scott 2004, pp. 1-2). A
study published in 2004 assessed the origin and local sale and export
of parrots and parakeets in Nicaragua (Herrera-Scott 2004, pp. 1-2),
and focused on the buffer zone of the Indio-Ma[iacute]z Biological
Reserve, a critical area for the great green macaw. The study followed
the marketing chain from rural areas to the capital city. Most of the
wildlife trade was found to occur in Managua. As of 2000, poaching was
still occurring in the buffer zone of the Indio-Ma[iacute]z Biological
Reserve (Herrera-Scott 2004, p. 6). An estimated 7,205 parrots were
sold during that year (Herrera-Scott 2004, p. 1). The legal export of
wildlife species from Nicaragua in general decreased significantly
between 2002 and 2006 (McGinley 2009, p. 16). Despite the decrease in
legal trade, in 2007, a number of parrot species could be still found
for sale along roads to tourists (Kennedy 2007, pp. 1-2; BLI 2007, p.
1). Nicaragua is the poorest country in Central America and the second
poorest in the Hemisphere, and has widespread underemployment and
poverty (CIA World Factbook 2011, unpaginated; FAO 2011, p. 1).
Approximately 17 percent of its population lives in extreme poverty
(Castellon 2008, p. 21). Many of Nicaragua's citizens live in rural
areas where they usually earn a living from agriculture and fishing,
and the sale of a parrot can significantly increase their earnings. As
mentioned above under the Factor A discussion, incomes in the Bosawas
region of Nicaragua were found to average under $800 per family per
year as of 2007 (Stocks et al. 2007, p. 1,498). The great green macaw
was found for sale at an average of $200 to $400 U.S. dollars (USD)
(Fundacion Cocibolca in BLI 2007, p. 1). For perspective, in the United
States, captive-bred specimens can sell for up to $2,500 USD (Basile
2009, p. 6). The high commercial value, especially in relation to the
average family income, indicates that it is still worthwhile to poach
and sell this species. Due to the extreme poverty in Central America,
particularly in Nicaragua, and due to the high commercial value of
great green macaws, poaching continues to be a significant concern for
this species.
Poaching can be intertwined with habitat destruction (Factor A).
Some poachers still cut down trees to obtain nestlings (Hardman 2011,
p. 13; Chun 2008, p. 105). This practice of cutting down trees to
remove nestlings is particularly devastating to small populations
reliant upon certain types
[[Page 60011]]
and sizes of nesting trees. Not only are poachers removing vital
members of the population, they are destroying a nest site that may
have taken a breeding pair several years to find and cultivate. One
study looked at 51 nest sites that had been identified between 1994 and
2003 (Chun 2008, p. 105). The study evaluated potential habitat by
examining the presence and density of almendro trees by aerial survey.
It examined portions of two protected areas--the San Juan-La Selva
Biological Corridor and the Maquenque National Wildlife Refuge (Chun
2008, p. 117). Of 51 nest sites, 10 trees had been cut by the end of
the survey period. In some cases, the nests had been deliberately cut
even after the tree had received protection status and had been
distinguished as a nesting tree with a plaque. Nest destruction has
also been reported in Ecuador (Bergman 2009, pp. 6-8), where it is
estimated to have an extremely small population. Another study
confirmed the presence of nest destruction, although this was a
different parrot species, and found an average of 21 nests was
destroyed per poaching trip (Gonzalez 2003, p. 443).
Poaching for the pet bird trade can destroy pair bonds, remove
potentially reproductive adults from the breeding pool, and have a
significant effect on small populations (Kramer and Drake 2010, pp.
511, 513). This is in part because this species mates for life, is
long-lived, and has low reproductive rates. These traits make them
particularly sensitive to the effects of poaching (Lee 2010, p. 3;
Thiollay 2005, p. 1121; Wright et al. 2001, p. 711). In some areas in
Costa Rica, there were no recent reports of nest poaching due to
conservation efforts (Villate et al. 2008, p. 23). However, despite
conservation efforts in place, the conservation workshop for Ara
ambiguus held in 2008 indicated that poaching of this species is still
a concern throughout its range (Monge et al. 2009, pp. 18, 26, 29, 40).
Summary of Factor B
Conservation efforts by various entities working to ensure the
long-term conservation of the great green macaw may result in its
population slowly increasing (Monge et al. 2010, pp. 12-13). However,
overall, the best available information indicates that the population
is still declining (Botero-Delgadillo and P[aacute]ez 2011, p. 91;
Monge et al. 2009). The species still faces threats such as habitat
loss and poaching. Often, there is a lag time after factors have acted
on a species (i.e., poaching and habitat loss) before the effect is
evident (Sodhi et al. 2004, p. 325). Even though the great green macaw
is listed as an Appendix-I species under CITES and commercial
international trade is now significantly reduced, there is still
concern about the illegal capture of this species in the wild. This
species is desirable as a pet, and its native habitat is in
impoverished countries, where the sale of an individual bird can
significantly increase an individual's income. Despite regulatory
mechanisms in place, poaching is lucrative and still occurs.
Additionally, because each population of great green macaws is small,
with possibly between 10 to 500 individuals (Monge et al. 2010, pp. 21,
22), poaching is likely to have a significant effect on the species.
The populations are distributed widely throughout the range of the
species (see Figure 3) and are highly fragmented, and the amount of
interaction between populations is unknown but likely infrequent. Based
on the best available information, we find that overutilization,
particularly due to poaching, is a threat to the great green macaw
throughout its range now and in the future.
C. Disease or Predation
We have no evidence of significant adverse impacts to wild
populations of great green macaws due to disease. Diseases are a normal
occurrence within wild populations. They do not occur to an extent that
they are a threat to this species, particularly because the populations
are widely dispersed, which provides an element of resiliency to the
overall population. We conclude, based on the best available scientific
and commercial information, that disease is not a threat to the great
green macaw now or in the future.
In addition, we have no information indicating that predation
threatens the great green macaw. This is the second largest New World
macaw, and the best available information does not indicate that
predation is a factor that negatively affects this species. While
predators undoubtedly have some effect on fluctuations in great green
macaw numbers, there is no evidence to suggest that predation has
caused or will cause long-term declines in the great green macaw
population. Therefore, we have determined that this factor does not
pose a threat to the great green macaw, now or in the future.
D. The Inadequacy of Existing Regulatory Mechanisms
Regulatory mechanisms affecting this species that we evaluated
could potentially fall under categories such as wildlife management,
parks management, or forestry management. We primarily evaluated these
regulatory mechanisms in terms of nationally protected parks because
this is where this species generally occurs. A summary of the status of
forest policies, regulatory mechanisms, and laws in the range countries
of the great green macaw is below. The most authoritative source for
assessing the state of forests is the United Nations Food and
Agriculture Organization's Forest Resources Assessment (FAO) (Chomitz
et al. 2007, p. 42). FAO's 2010 study found that each range country for
this species has a national forest law, policy, or program in place,
and Table 1 indicates the year it was last evaluated. However, the
study found that few forest policies at the subnational level (such as
jurisdictions equivalent to states in the United States) exist in these
countries.

[[Page 60012]]
In 2007, FAO noted that many countries (in the range of the great
green macaw) had enacted new forest laws or policies within the past 15
years, or had taken steps to strengthen their existing legislation or
policies. Among countries that had enacted new forest legislation were
Costa Rica, Honduras, Nicaragua, Panama, Colombia, and Ecuador (FAO
2007, p. 43). Despite the existence of these laws and policies, the
populations of the great green macaw are still negatively affected by
habitat loss, encroachment, and, to a lesser extent, poaching.
Parks and Habitat Management
Throughout this species' range, we found that many of the threats
that occur to this species are the same or similar. Threats generally
consist of various forms of habitat loss or degradation (see Factor A
discussion, above). Each range country for this species has protections
in place, but for reasons such as limited budgets and limited
enforcement capabilities, the laws and protections are generally not
able to adequately protect the species. Our analysis of regulatory
mechanisms is discussed essentially on a country-by-country basis,
beginning with Colombia, and is summarized at the end.
Colombia
Colombia has enacted numerous laws to protect species and their
habitats. This species exists predominantly in areas that are
protected, and Colombia has several laws that pertain to protected
areas. Some of these laws include:
Natural Resources and Decree Law number 2811/74.
Decree 1974/89: Regulation of Article 310 of Decree 2811,
1974, on integrated management districts of natural renewable
resources.
Law number 99/93: Creates the Ministry of the Environments and
the National Environmental System.
Law number 165/94: Biological Diversity Treaty.
Decree 1791/96: Establishment of the Forest Use Regime.
A list of legislation that applies to protected areas in Colombia is
available at https://www.humboldt.org.co/ingles/en-politica.htm and at
https://www.regulations.gov in Docket No. FWS-R9-ES-2011-0101. A
discussion of Colombia's regulatory mechanisms with respect to the
great green macaw follows.
The great green macaw is listed as vulnerable on Colombia's Red
List (Renjifo et al. 2002, p. 524). Resolution No. 584 of 2002 provides
a list of Colombian wildlife and flora that are considered
``threatened.'' Colombia defines threatened as those species whose
natural populations are at risk of extinction if their habitat, range,
or the ecosystems that support them have been affected by either
natural causes or human actions. Threatened species are further
categorized as critically endangered, endangered, or vulnerable.
Colombia defines a critically endangered species as one that faces a
very high probability of extinction in the wild in the immediate
future, based on a drastic reduction of its natural populations and a
severe deterioration of its range. An endangered species is one that
has a high probability of extinction in the wild in the near future,
based on a declining trend of its natural populations and a
deterioration of its range. A vulnerable species is one that is
described as not in imminent danger of extinction in the near future,
but it could be if natural population trends continue downward and
deterioration of its range continues (EcoLex 2002, p. 10).
Colombian Law No. 99 of 1993 created the Ministry of the
Environment and Renewable Natural Resources and the National
Environmental System (SINA). SINA sets out the principles governing
environmental policy in Colombia, and provides that the country's
biodiversity is protected and used primarily in a sustainable manner
(Humboldt Biological Resources Research Institute 2011, unpaginated;
EcoLex 1993, p. 2). SINA is a set of activities, resources, programs,
and institutions that allow the implementation of environmental
principles. Consistent with the Constitution of 1991, this management
system was intended to be decentralized. However, an environmental
assessment study conducted for the World Bank in 2006 found that
Colombia's current decentralized system is inadequate as implemented
(Blackman et al. 2006, p. 15). Although Law 99 assigns the role of
leading and coordinating environmental management in Colombia to the
Ministry of Environment (Ministerio del Medio Ambiente, MMA),
Colombia's Autonomous Regional Corporations (CARs) have the role of
implementing environmental laws (Blackman et al. 2006, pp. 39-40, 42).
CARs have responsibility for both management of natural resources and
economic development (Ministry of Environment et al. 2002).
In 2006, an analysis of the effectiveness of Colombia's CARs was
conducted for the World Bank. In Blackman et al. 2006's analysis, they
reported that many individuals both inside and outside the government
felt there was a lack of effectiveness of SINA. For example, Colombia's
efforts to eradicate the coca trade has not been effective at reducing
the amount of coca being cultivated (Page 2003, p. 2; also see The
present or threatened destruction, modification, or curtailment of its
habitat or range). In addition to not adequately addressing the coca
cultivation, which destroys the great green macaw's habitat, aerial
fumigations of the coca crop have destroyed banana fields and polluted
the environment (Page 2003, p. 2). The effectiveness of these regional
management groups varied; the study found that the effectiveness was
correlated with the CARs' age, geographic size, and level of poverty
(Blackman et al. 2006, p. 16). Due to the decentralized structure, CARs
were found to be ineffective at environmental management in Colombia
(Blackman et al. 2006, p. 14).
This species' habitat occurs to some extent in areas designated as
protected by SINA, including five national parks (Rodr[iacute]guez-
Mahecha 2002a). Two parks are particularly significant: Kat[iacute]os
National Park and Utr[iacute]a National Park. Although this species
likely exists in at least these two parks (Botero-Delgadillo and
P[aacute]ez 2011, p. 92), no protective measures have been actually
implemented to curb human impacts on the species' habitat by the
indigenous and farming residents within these protected parks (Botero-
Delgadillo and P[aacute]ez 2011, p. 92). Cultivation of plants for
cocaine production is known to occur within the boundaries of
Kat[iacute]os National Park. The cultivation of illegal crops
(particularly coca) poses additional threats to the environment beyond
the destruction of montane forests (Balslev 1993, p. 3). Coca crop
production destroys the soil quality by causing the soil to become more
acidic, depletes the soil nutrients, and ultimately impedes the
regrowth of secondary forests in abandoned fields (Van Schoik and
Schulberg 1993, p. 21; also see The present or threatened destruction,
modification, or curtailment of its habitat or range discussion,
above). As of 2007, Colombia was the leading coca producer (United
Nations Office of Drugs and Crime (UNODC) et al. 2007, p. 7). Since
2003, cocaine coca cultivation has remained stable at about 800 km\2\
(309 mi\2\) of land under cultivation (UNODC et al. 2007, p. 8). This
activity continues to degrade and destroy great green macaw's habitat.
With respect to Utr[iacute]a National Park, little to no information is
known about the status of the species in
[[Page 60013]]
this area (Botero-Delgadillo and P[aacute]ez 2011, p. 91). Although it
is extremely remote, human communities reside within and around the
park, and continue to use the resources within the park.
Despite Colombia's numerous laws and regulatory mechanisms to
administer and manage wildlife and their habitats, the great green
macaw continues to face many threats to its habitat. There is little
information available about the species (Botero-Delgadillo and
P[aacute]ez 2011, p. 90), and the most recent information indicates
that no conservation action has been proposed for this species (Botero-
Delgadillo and P[aacute]ez 2011, p. 88). On-the-ground enforcement of
existing wildlife protection and forestry laws, and oversight of the
local jurisdictions implementing and regulating activities, are
ineffective at mitigating the primary threats to the great green macaw.
As discussed under The present or threatened destruction, modification,
or curtailment of its habitat or range (above), habitat destruction,
degradation, and fragmentation continue throughout the existing range
of the great green macaw. Therefore, we find that the existing
regulatory mechanisms currently in place are inadequate to mitigate the
primary threats of habitat destruction to the great green macaw in
Columbia.
Costa Rica
In Costa Rica, there are more than 30 laws related to the
environment (Peterson 2010, p. 1). A list of the environmental laws in
Costa Rica is available at: https://www.costaricalaw.com/costa-rica-environmental-laws.html. As deforestation is the most significant
factor affecting the great green macaw, some laws applicable to the
conservation of the great green macaw are:
Law No. 2790 Wildlife Conservation Law (``Ley De
Conservaci[oacute]n De La Fauna Silvestre,'' July 1961).
Law No. 7317 Wildlife Conservation Law (``Ley De
Conservaci[oacute]n De La Vida Silvestre,'' December 1992).
Law 7554 Law of the Environment (``Ley Org[aacute]nica del
Ambiente,'' October 1995).
Law No. 7575 Forestry Law (``Ley Forestal,'' February 1996).
Law 7788 Biodiversity Law (In 1998, the National System of
Conservation Areas (SINAC) was created through this law (Canet-Desanti
2007 in Villate et al. 2008, p. 24).
In the early 1990s, Costa Rica had one of the highest deforestation
rates in Latin America (Butler 2012, p. 3). Forest cover in Costa Rica
steadily decreased from 85 percent in 1940, to around 35 percent today,
according to the FAO's State of the World's Forests (Butler 2012,
unpaginated; FAO 2010, pp. 227, 259; FAO 2007). Historically, clearing
for agriculture, particularly for coffee and bananas, in addition to
cattle pastures was the main reason for Costa Rica's rainforest
destruction. During the 1970s and early 1980s, vast expanses of
rainforest had been burned and converted to cattle pastures. Today,
although deforestation rates of natural forest have dropped
considerably, Costa Rica's remaining forests still experience illegal
timber harvesting (in protected areas) and conversion to agriculture
(in unprotected zones) (Butler 2012, unpaginated; Monge et al. 2009, p.
121; FAO 2007). Despite its abundance of conservation legislation,
Costa Rica has undergone significant periods of deforestation (Butler
2012, unpaginated; FAO 2007, p. 38), which have had a severe effect on
the great green macaw.
Almendro Tree Protection
In Costa Rica and Nicaragua, the great green macaw is highly
dependent on the almendro tree. This tree species is now protected by
law in Costa Rica; cutting any almendro tree over 120 cm (47.2 in) or
less than 70 cm (27.6 in) in diameter is prohibited (Rainforest
Biodiversity Group 2008, p. 1). The remaining Costa Rican populations
of almendro trees are concentrated in the northeastern corner of the
country from the San Juan River south to Braulio Carrillo National Park
(Hanson 2006, p. 3). Although little forest remains undisturbed in this
region, many almendro trees were left standing in fragments or
pastures, partly due to the extremely dense nature of the tree's wood
and the difficulty in cutting down these trees.
As a result of the great green macaw's dependence on almendro
trees, conservation efforts for the great green macaw have focused on
this tree species. A decree was enacted in 2001 to limit extraction of
the almendro tree. Harvest was temporarily suspended until a study
could be conducted to evaluate the status of this primary food and
nesting source in relation to the great green macaw (Chosset et al.
2002, p. 6). According to Costa Rican legislation (Decree No 25167-
MINAE), the removal or logging of almendro trees had been illegal in
the area between the San Carlos and Sarapiqui Rivers (Madriz-Vargas
2004, p. 9). The objective of the restrictions placed on extraction of
almendro trees was to increase the number of nesting sites for the
great green macaw and to prevent the tree from becoming extinct;
however, forest clearings continued to occur at an alarming rate due to
the lack of resources to protect biological reserves (Madriz-Vargas
2004, p. 8). For example, researchers reported in 2003 that, of the 60
great green macaw nests identified since the great green macaw
conservation project was initiated in 1994, 10 had been cut down by
forest engineers working in forest management plans (Monge and Chassot
2003, p. 4). In 2008, Costa Rica's Supreme Court stated that MINAE must
abstain from the continuation or initiation of the use, exploitation,
or extraction of the almendro tree (Chun 2008, p. 113). In Costa Rica,
fines for those who cut down almendro trees have been proposed as a
measure, although penalties reportedly have not been instituted
(Botero-Delgadillo and P[aacute]ez 2011, p. 92).
Great Green Macaw Conservation
In the two core areas where the great green macaw exists in Costa
Rica, conservation activities are under way, and the breeding
populations are being closely monitored. Quebrada Grande is a
community-operated, 119-ha (294-ac) reserve in the center of great
green macaw habitat. Additionally, the National Green Macaw Commission
was formed in 1996 to protect and manage this species' habitat. This
commission was formed in response to the severe decline of the great
green macaw population, and included 13 government agencies, NGOs, and
the Sarapiqu[iacute] Natural Resources Commission (CRENASA). This
conservation effort was formalized by Executive Order No. 7815-MINAE of
1999. The group served as an advisory body to MINAE regarding
environmental issues in the northern zone of Costa Rica that affect the
great green macaw (Chassot and Monge 2008 in Villate et al. 2008, p.
22). Conservation efforts are still in progress; in 2008, a workshop
was held to bring together species experts and government officials to
identify priorities and goals in order to conserve the species (Monge
et al. 2009, entire).
Additionally, a corridor was created in 2001, with the goal of
maintaining connectivity and biodiversity between protected areas in
southeastern Nicaragua, the Protected Conservation Area Arenal Huetar
North (ACAHN), and Conservation Area of the Central Volcanic Cordillera
(ACCVC) in Costa Rica. The primary purpose was to promote the creation
of protected wilderness and encourage habitat protection necessary to
preserve and
[[Page 60014]]
increase the great green macaw population (Villate et al. 2008, p. 24).
In 2005, the Maquenque National Wildlife Refuge (MNWR) was
established primarily to protect breeding habitat for the great green
macaw. Approximately 43,700 ha (107,985 ac) of land identified as
potential great green macaw breeding habitat lies within the boundaries
of MNWR (Chun 2008, p. 113). This region was targeted because it
contains several large nesting trees used by great green macaw breeding
pairs. MNWR protects foraging habitat that may be critical during the
great green macaw's breeding season. MNWR is within the larger San Juan
La Selva (SJLS) Biological Corridor, and its goal is specifically to
connect protected areas in southern Nicaragua to those in central Costa
Rica (Chun 2008, p. 98). However, even in this refuge, habitat
degradation continues to occur. A RAMSAR (the Convention on wetlands)
report on this refuge (which is a RAMSAR site), indicated that the main
threats there are agricultural and forestry activities, which are most
prevalent near the Colpach[iacute] and Manat[iacute] lagoons (RAMSAR
2012, p. 1).
In summary, as of 2002, less than 10 percent of the great green
macaw's original range was estimated to exist in Costa Rica (Chosset et
al. 2002, p. 6). The great green macaw greatly depends on the almendro
tree as its primary food and nesting resource. However, due to Costa
Rica's complex deforestation history, the great green macaw remains
imperiled primarily due to habitat fragmentation, degradation, and
habitat loss. In 2004, a maximum of 35 pairs were estimated to be
breeding in northern Costa Rica (Chosset et al. 2004, p. 32), and the
population in this country appears to have increased since a
conservation program and regulatory mechanisms have been in place.
Costa Rica's population was estimated to be approximately 300 birds in
2010 (Chassot 2010 pers. comm. in Hardman 2011, p. 11; Monge et al.
2010, pp. 13, 22). Despite the apparent increase in the population in
Costa Rica, the population is extremely small and has experienced
significant decline in available habitat over the past 60 years.
Habitat Degradation
In addition to the historical loss of habitat, the species
continues to face threats such as habitat degradation. This species
requires a complex suite of plant species over the course of a year for
its nutritional needs. Pressures to its habitat such as logging,
encroachment, habitat degradation, and likely other factors continue
within this species' range. Despite conservation efforts in place, such
as conservation awareness programs, research, and monitoring, the
population has declined significantly over time and is still only
estimated to be approximately 300 individuals. Because this species
mates for life and has a small clutch size, the loss of any one
individual can have a significant effect on the population. Costa Rica
has implemented many environmental laws in conjunction with
conservation efforts to protect species, particularly the great green
macaw and its habitat. The situation of this species is still
precarious, and any of the threats acting on the species, such as
habitat loss and degradation, poaching, or other unknown factors, could
have a significant effect on the population in Costa Rica because it is
so small, and because of its life-history characteristics. The existing
regulatory mechanisms, as implemented, are insufficient in Costa Rica
to adequately ameliorate the current threats to this species.
Ecuador
As of 2006, the Ecuadorian Government recognized 31 various legal
categories of protected lands (e.g., national parks, biological
reserves, geobotanical reserves, bird reserves, wildlife reserves,
etc.). The amount of protected land (both forested and non-forested) in
Ecuador as of 2006 was approximately 4.67 million ha (11.5 million ac)
(ITTO 2006, p. 228). However, only 38 percent of these lands had
appropriate conservation measures in place to be considered protected
areas according to international standards (i.e., areas that are
managed for scientific study or wilderness protection, for ecosystem
protection and recreation, for conservation of specific natural
features, or for conservation through management intervention) (ITTO
2009, p. 1). Moreover, only 11 percent had management plans, and less
than 1 percent (13,000 ha or 32,125 ac) had implemented those
management plans (ITTO 2006, p. 228).
In 2004, the Ecuadorian Minister of the Environment signed a
ministerial decree forming the National Strategy for the In-Situ
Conservation of the Guayaquil Macaw (Ara a. guayaquilensis) into law
(ProForest 2005, p. 3). The strategy included the following components
to be implemented within 10 years. Aspects of this conservation plan,
which focuses on the Cerro Blanco Protected Forest, a stronghold for
great green macaw, include:
Applied investigation for the conservation of the species;
Management of the conservation areas where the presence of
the Guayaquil macaw has been confirmed, incorporating new areas that
are critical for conservation of the species, and providing connecting
corridors between the areas;
Reforestation with appropriate tree species in its
habitat;
Incentives and sustainable alternatives for communities
and private property owners within its range; and
Conservation of the Guayaquil macaw.
Despite the existence of this strategy, the great green macaw still
faces significant threats in Ecuador (Horstman 2011, p. 12). There are
likely fewer than 100 individuals of this subspecies remaining in
Ecuador. Ecuador recognizes that threats exist to its natural heritage,
not only to this species, but to all of its wildlife. In 2008, Ecuador
approved Article 71 of its Constitution, which states, ``Nature has a
right to integrally respect its existence as well as the maintenance
and regeneration of its vital cycles, structures, functions and
evolutionary processes.'' Article 73 also mandates, ``measures of
precaution and restriction for all activities that could lead to the
extinction of species, the destruction of ecosystems, or the permanent
alteration of natural habitats.''
Ecuador has made significant strides in conservation. Ecuador's
Article 103 of Book IV on Biodiversity decreed that: ``It is
prohibited, on any day or time of the year, to hunt species, whether
birds or mammals, that constitute wildlife and that are listed in
Appendix 1 of the present Record that are qualified as threatened or
endangered. Hunting is likewise prohibited in certain areas or zones
while the bans are in effect'' (Monge et al. 2009, p. 256; Unified Text
of the Secondary Legislation of the Ministry of the Environment).
Despite the recent advances made in conservation efforts, Ecuador has
gone through periods of devastating habitat loss and degradation, which
affected the great green macaw's habitat such that it only remains in
two fragmented and small areas. It is unclear how sustainable the
remaining habitat is, particularly because this species has specialized
feeding requirements and requires a large range to provide its
nutritional needs.
The National Strategy for the In-Situ Conservation of the Guayaquil
Macaw was revised in 2009. As a result, the first national census of
great green macaw was conducted in Ecuador in late 2010 (Horstman 2011,
pp. 16-17). The Cerro Blanco Protected Area has been managed by the
Pro-Forest Foundation, an NGO, for approximately 20 years (Horstman
2011, unpaginated).
[[Page 60015]]
Horstman indicated that, at the Cerro Blanco Reserve, the resident
population of approximately 15 macaws travels widely outside of the
6,475-ha (16,000-ac) reserve (https://blogs.discovery.com/animal_news/2009/11/help-for-ecuadors-great-green-macaws.html, accessed October 28,
2011). Horstman, who has worked in this area since the early 1990s,
indicated the need to establish a conservation corridor between Cerro
Blanco and adjacent patches of suitable forest, and most are less than
40.5 ha (100 ac) in size. During the past 20 years, at least 2,000 ha
(4,942 ac) have been reforested (Monge et al. 2009, p. 9). Although
reforestation projects have occurred, encroachment is still occurring
(Horstman 2011, p. 12). Despite conservation efforts and regulatory
mechanisms in place, there is still limited funding available for
conservation efforts. Encroachment and other forms of habitat
degradation continue to occur within its habitat (see Factor A
discussion, above). Therefore, we find that the regulatory mechanisms
are inadequate to ameliorate the loss and degradation of great green
macaw habitat in Ecuador.
Honduras
The National Conservation and Forestry Institute (ICF) (formerly
the Protected Areas and Wildlife Department, established in 1991) is
responsible for regulating natural resources and management of
protected areas. The National Protected Areas System includes 17
national parks created between 1980 and 2007. As of 2009, there were 79
protected areas (Triana and Arce 2012, p. 1). In 1991, the Protected
Areas and Wildlife Department (which is now the National Conservation
and Forestry Institute (ICF)) was designated to manage natural
resources and protected areas (Devenish et al. 2009, p. 257; Decree no.
74-91, 1991). Prior to 1991, wildlife was managed by the Honduran
Department of Wildlife and Ecology (RENARE).
Decree 98-2007, the Forest Law of Honduras, repealed Decree 163-93
of 1993, which contained the Law on Incentives for Forestation,
Reforestation, and Forest Protection. The Forest Law sets forth the
purposes of the law, and regulates the use of forestry areas, the
rational and sustainable management of forestry resources, protected
areas, and wildlife. The law contains definitions and created a series
of administrative agencies charged with the implementation of forestry
regulations, including the National Forestry Consultative Council. This
law also formed the National Forestry Research System and the National
Institute for Forestry Conservation and Development (211 provisions;
pp. 1-17).
Before the 2007 Forest Law was approved, at least 38 laws governed
the sector, creating a confusing policy framework. The situation is
further complicated because, in many cases, forest tenure (ownership,
tenancy, and other arrangements for the use of forests) is unclear.
Although most forest is officially state-owned (FAO 2007), states have
little practical authority over forest management, and individuals
exercise de facto ownership. Corruption is a barrier to legal logging
because it facilitates illegal operations and creates obstacles to
legal ones (Pellegrini 2011, p. 18; Rodas et al. 2005, p. 53). Bribes
are extorted from certified community forestry operations, and,
reportedly, without bribes, transport of legal wood becomes impossible
(Pellegrini 2011, p. 18; Rodas et al., 2005, p. 53).
The new 2007 Forest Law was supported by environmental groups, but
its implementation was delayed. The law included the abolition of the
Honduran Forest Development Corporation (COHDEFOR) (which received
unanimous support), more resources for enforcement, and harsher
penalties against those who commit forest-related crimes. Previously,
the director of COHDEFOR and other political leaders were owners or
employees of logging companies, an apparent conflict of interest
(Pellegrini 2011, p. 20). Also at that time, the army was involved in
enforcement. Out of the resources that were spent for the forestry
sector, the military absorbed 70 percent without producing any evidence
that enforcement had improved (Pellegrini 2011, p. 20).
Currently in Honduras, the great green macaw is believed to exist
in eastern Honduras in suitable habitat distributed from Olancho to the
R[iacute]o Pl[aacute]tano Biological Reserve, the Tawahka Biological
Reserve, and Patuca National Park (Monge et al. 2009, p. 39). Its range
encompasses both unprotected and protected areas; however, timber
exploitation occurs even in areas designated as protected. This
practice has created conflicts in protected areas such as the
R[iacute]o Pl[aacute]tano Biosphere Reserve, an area that is considered
critical for its conservation (Lopez and Jim[eacute]nez 2007, p. 26).
Demand for mahogany, which has been one of the most extracted species
in the area (Lopez and Jim[eacute]nez 2007, p. 26), has also put
pressure on this species' habitat. Selective logging creates openings
in forest canopies and changes the ecosystem dynamics and composition
of plant species. Income from logging is higher than that earned for
crops and cattle, making logging far more lucrative for locals.
However, after areas are logged, they become more accessible and are
then often converted to uses such as crops and cattle grazing.
Indigenous communities have rights to use many protected areas.
Article 107 of the Honduran Constitution protects the land rights of
indigenous people. It is the duty of the government to create measures
to protect the rights and interests of indigenous communities in the
country, especially with respect to the land and forests where they are
settled (Article 346). As an example of land use by Honduran indigenous
communities, between 15 and 40 percent of the total value of
consumption for two indigenous Tawahka communities was found to be
derived directly from the forest (Godoy et al. 2002, p. 404). Struggle
over land rights is a difficult issue for indigenous communities in
Honduras. Logging and mining are some of the biggest threats not only
to the great green macaw, but also to the indigenous communities.
Indigenous cultures generally have a low impact on the forests (Stocks
et al. 2007, pp. 1,502-1,503). Because indigenous communities want
their lands protected for their traditional way of life, NGOs are
working with these communities to protect reserves in Honduras, which
should ultimately benefit the great green macaw.
In 1996, the R[iacute]o Pl[aacute]tano Biosphere Reserve was placed
on the ``World Heritage Site in Danger'' list, but it was removed from
the list in 2007, due to a significant improvement in conservation
efforts by NGOs. Several NGOs are working in this area including the
Mosquitia Paquisa (MOPAWI) and the Rio Pl[aacute]tano Biosphere Project
(UNEP-WCMC 2011, p. 5). However, investigations in 2010 and 2011
indicate that there are still problems within the reserve (UNESCO 2011,
pp. 1-3). UNESCO, as recently as 2011, conducted a survey in the
R[iacute]o Pl[aacute]tano Reserve and found illegal activity within the
core zone (UNESCO 2011, pp. 1-3). Clearing of land for cattle grazing
and illegal fishing and hunting along the river is ongoing. The area is
protected by policy by the Department of Protected Areas and Wildlife,
State Forestry Administration in Honduras. The reserve management plan,
implemented in 2000, included zoning and specific plans for
conservation issues. One of the goals of the reserve's conservation
plan is to integrate local inhabitants with their environment in part
via sustainable agricultural practices. This practice has been found to
be a good tool in forest conservation (Pellegrini 2011, pp. 3-8). The
reserve
[[Page 60016]]
plan established buffer zones, cultural zones, and nucleus zones.
Indigenous communities living in the reserve and buffer zone are
allowed to use the resources within the reserve. The integration of
indigenous populations plays a large part in the success of the
conservation plan, both inside the reserve and outside the reserve in
the buffer and peripheral zones (Pellegrini 2011, p. 3; Stocks et al.
2007, pp. 1502-1503). This reserve also receives some funding from the
World Wildlife Fund and other private organizations that assist in the
management of the reserve. However, there are currently no park guards
or any official entity actively patrolling or guarding the reserve to
enforce restrictions.
There is a complex history concerning the balance of land rights of
indigenous communities and preservation of habitat for species such as
the great green macaw. In Honduras, there is a gap between forestry
policy objectives and the state of forestry. The policy frameworks
exist to manage timber extraction, but tools are not implemented
(Pellegrini 2011, p. 1). COHDEFOR had been responsible for forestry
development and enforcement of laws. The Honduran Government began to
decentralize COHDEFOR beginning in 1985 (Butler 2012, unpaginated) due
to its ineffectiveness. As of 2001, the management of Honduran forests
was administered by the Administraci[oacute]n Forestal del Estado (AFE,
Government Forestry Administration), Corporaci[oacute]n
Hondure[ntilde]a de Desarrollo Forestal (COHEFOR Honduran Forestry
Development Corporation) (Moreno and Marineros 2001, p. 2). Land use
planning occurs at the national level; however, identifying the best
use of areas has not been implemented (Pellegrini 2011, p. 17). In
addition, estimates of illegal logging are approximately 80 percent of
the total volume extracted for broadleaf and 50 percent for coniferous
species (Richards et al. 2003, p. 1).
Honduras is making progress in managing its forested resources. In
2010, Honduras implemented Agreement number 011-2010 (Ecolex 2011), the
Forestry Reinvestment Fund and Plantation Development, and its goal is
to recover areas of degraded or denuded forests. In 2010, Honduras also
put into place Decision No. 31/10, the General Regulation of Forestry
Law, Protected Areas and Wildlife (Ecolex 2011). This covers the
administration and management of forest resources, protected areas, and
wildlife. Despite the progress made in Honduras with respect to laws
and regulatory mechanisms that affect the great green macaw and other
wildlife, the species continues to face habitat loss and degradation in
Honduras.
Nicaragua
Nicaragua's General Environmental and Natural Resources Law No.
217, issued in 1996, is considered the legal framework that defines the
standards and mechanisms in regard to the use, conservation,
protection, and restoration of the environment and natural resources in
a sustainable manner. It recognizes the sustainable development
concept. By 2004, Nicaragua had enacted 10 environmental laws and was a
member of regional and international environmental agreements (Moreno
2004, p. 9). As of 2004, Nicaragua was moving towards the consolidation
of a National System of Protected Areas (SINAP) in order to preserve
the country's biological wealth (Moreno 2004, p. 9). SINAP consists of
National Protected Areas, Municipal Ecological Parks, and Private
Wildlife Reserves of ``ecological and social relevance at the local,
national, and international level, defined in conformance with the law,
and designated according to management categories that permit
compliance with national policies and objectives of conservation''
(McGinley 2009, p. 19; Protected Areas Regulations: Article 3).
However, the overall protection and administration of SINAP is hindered
by an inability to administer its financial and human resources
(McGinley 2009, p. 20). Of the 72 national protected areas, only 23 had
approved management plans in 2008, another 19 were in some phase of the
approval process, and 30 protected areas had no management plan at all
(McGinley 2009, p. 20). Despite protections in place, enforcement has
been lacking in protected areas, and poverty continues to be a huge
concern in Nicaragua (FAO 2011, pp. 1-2; McGinley et al. 2009, p. 16).
Three assessments of the effectiveness of Nicaragua's laws and
regulations with respect to wildlife and forestry laws were recently
conducted (Pellegrini 2011; McGinley et al. 2009; Castell[oacute]n et
al. 2008). The first explored the relationship between forest
management and poverty (Pellegrini 2011). The research published in
2009 evaluated Nicaragua's Tropical Forests and Biological Diversity
(McGinley et al. 2009, entire). The other report evaluated the
effectiveness of Nicaragua's wildlife trade policies
(Castell[oacute]n.et al. 2008, entire). In Nicaragua, the organization
responsible for regulation and control of the forestry sector is the
National Forest Institute (INAFOR), which is under the Ministry of
Agriculture, Livestock and Forestry (MAGFOR). The other relevant
ministry is the Nicaraguan Ministry of Environment and National
Resources (MARENA), which supports conservation awareness programs for
this species. In early 2003, MARENA created the Municipal Environmental
Unit in order to decentralize environmental functions. Although a good
legal framework exists in Nicaragua to protect its natural resources,
there are still on-the-ground problems that affect this species. For
example, in the Indio-Ma[iacute]z Biological Reserve, one of the
strongholds for this species, each forest guard in the control posts
along the border of the reserve is responsible for monitoring a stretch
of 8 km (5 mi) of the border and an area of 70 km\2\ (27 mi\2\) (Rocha
2012, pp. 3-6; Ravnborg et al. 2006, p. 6). There are communication and
perception problems that are prevalent within the reserve that
perpetuate the inability to adequately manage the resources within the
reserve. These resources are used both legally and illegally by Costa
Ricans who cross the San Juan River and the local communities who live
in Nicaragua (Rocha 2012, pp. 3-6).
In 2008, the Government of Nicaragua published a report on the
status of its wildlife laws and mechanisms (Castellon et al. 2008,
entire). It reported the following findings (p. 9):
Nicaragua's current laws are inadequate to protect and
sustain domestic and international trade in CITES species. They are
unfocused and lack provisions on habitat degradation and biological
productivity.
Nicaragua does not have a written wildlife trade policy or
laws to underpin sustainable species management in domestic and
international trade. The regulatory instruments pertaining to
sustainable management of wildlife trade are relevant and coherent and
provide a basis for the formulation of such a policy.
The nonregulatory instruments for measuring the commercial
sustainability of wildlife trade are rarely used. The most important of
them are: monitoring, research, education, and information.
Study of wildlife harvesting shows that the income from
trade in harvested species goes principally to external actors, with
little or no benefit to rural communities or populations.
The 2008 study also reported that the Government of Nicaragua was
unable to find a single case in which the application of its laws led
to actual fines or penalties for harvesting or trading banned species
(McGinley 2009, p. 22). It found that nonregulatory instruments
[[Page 60017]]
such as monitoring, research, education, and information are poorly
used in the oversight of commercial wildlife trade in Nicaragua
(McGinley 2009, p. 22). Despite these findings, a review undertaken by
the CITES Secretariat found that the legislation of Nicaragua has been
determined to be sufficient to properly implement the CITES Treaty (see
discussion below). The country has made an effort to protect its
resources and is attempting to address the management of its natural
resources.
In addition, specific, targeted conservation measures are
occurring. An NGO in Nicaragua, with the support of MARENA, is
promoting conservation of this species. They have initiated a campaign
to educate communities in part by posting messages on buses on three
highly traveled public routes in Managua. For example, one message
describes why buying endangered species as pets is not a good idea;
rather, they should remain in the wild. Additionally, in 2003,
Nicaragua and Costa Rica participated in the First Mesoamerican
Congress for Protected Areas. Senior representatives of both countries
discussed ways to explore the framework of connectivity between
protected areas (Villate et al. 2008, p. 52). As a result, several
active conservation measures for the great green macaw in Nicaragua are
under way, such as the development of connected habitat corridors, and
the great green macaw conservation workshop was held in 2008. In
Nicaragua's Indio-Ma[iacute]z Biological Reserve, training measures for
monitoring the great green macaw have been implemented. For example,
technicians associated with Fundacion del Rio have been trained in
great green macaw research (Chassot et al. 2006, p. 86). The species'
population is estimated to be only 871 individuals in Nicaragua and
Costa Rica combined (Monge et al. 2010, p. 21), and pressures continue
to occur to the species and its habitat. Despite regulatory mechanisms
in place and the existence of many strategies in Nicaragua to combat
threats to the species such as deforestation, habitat loss, and
poaching for the wildlife trade, these activities continue.
The impoverished rely strongly on forest products (Pellegrini 2011,
pp. 21-22). In an attempt to reduce poverty and at the same time
conserve forested areas, analyses addressing poverty reduction were
conducted prior to 2002. Strategies, described as Poverty Reduction
Strategy Papers (PRSPs), recommended approving a forestry law by 2002
(which actually was approved at the end of 2003) and addressing
deforestation as a source of ecological vulnerability. As part of its
poverty reduction strategy, Nicaragua developed a National Development
Plan (Government of Nicaragua 2005 in Pellegrini 2011, pp. 21-22), the
goal of which was to strengthen the whole forestry production chain.
However, the plan was reported not to have been effectively implemented
(Pellegrini 2011, p. 22). The main policy instruments that set the
framework for forestry were the Forest Law and the logging ban. The
Forest Law establishes the system of forest management (Pellegrini
2011, pp. 21-22). The law includes incentives for sustainable
practices; however, Pellegrini noted that it is virtually impossible to
take advantage of the law's provisions without support by external
organizations such as NGOs (Pellegrini 2011, p. 22; TNC 2007, pp. 3-7).
Nicaragua is focusing efforts on the restoration and protection of
forested areas, and its goal was to reduce the deforestation rate from
70,000 ha (172,974 ac) to 20,000 ha (49,421 ac) per year by 2010
(McGinley 2009, p. 28). Recently, the Associated Foresters of Nicaragua
(FORESTAN), in cooperation with a local NGO, the Instituto de
Investigaciones y Gesti[oacute]n Social (INGES), began an initiative to
increase forest cover. Their goal is to incorporate conservation and
production areas over 5,000 ha (12,355 ac), and more effectively use
commercially valuable tree species while at the same time creating
permanent jobs (INGES-FORESTAN 2005 in Sinreich 2009, p. 63). In 2006,
a logging ban was put in place. The ban prohibited extraction of six
species of wood and any logging operation in protected areas or within
15 km (9 mi) of all national borders, and it put the army in charge of
enforcement (Government of Nicaragua 2006 in Pellegrini 2011, p. 23).
However, deforestation rates may have increased even after the ban's
approval (Guzm[aacute]n 2007, pp. 1-2). Although Nicaragua attempts to
manage its natural resources, it has a large challenge due to the
pressures for its forest resources in combination with extreme poverty
(FAO 2011, p. 1; McGinley et al. 2009, p. 11). Despite these efforts,
pressure on the great green macaw's habitat continues.
Panama
In Panama, the great green macaw's stronghold is believed to be in
Dari[eacute]n National Park, which borders Colombia (Monge et al. 2009,
p. 68; Angehr in litt. 1996 in Snyder et al. 2000, pp. 121-123; Ridgley
1982). The Dari[eacute]n region encompasses nearly 809,371 ha (2
million ac) of protected areas, including Dari[eacute]n National Park
and Biosphere Reserve, Punta Pati[ntilde]o Natural Reserve, Brage
Biological Corridor, and two reserves for indigenous communities (TNC
2011, p. 1). Panama's National System of Protected Areas (SINAP) is
managed by the National Environmental Authority (ANAM) and consists of
66 areas, totaling 2.5 million ha (6.18 million ac) (Devenish et al.
2009b, pp. 1-2). Of these, 19 have management plans, and 36 have been
through a process of strategic planning (ANAM 2006, unpaginated).
ANAM was established in 1998, through the General Environmental Law
of Panama (Law 41). ANAM is the primary government institution for
forest and biodiversity conservation and management. ANAM plans,
coordinates, regulates, and promotes policies and actions to use,
conserve, and develop renewable resources of the country. Its mission
statement is to guarantee a healthy environment through the promotion
of rational use of natural resources, the organization of environmental
management, and the transformation of Panamanian culture to improve the
quality of life (Virviescas et al. 1998, p. 2). Law 41 also provides
the framework for SINAP. Environmental protection in Panama falls under
the jurisdiction of three government agencies, the Institute for
Renewable Natural Resources, the Ministry of Agricultural Development,
and the Ministry of Health. There are 17 management categories of
protected areas that were established through INRENARE's Resolution 09-
94. A later law, the Forest Law of 2004, established protections for
three types of forest, which covers 36 percent of the country.
There are political and economic pressures to develop many areas
(Devenish et al. 2009b, p. 291). Deforestation, in addition to the lack
of management, and lease periods for these concessions of 2 to 5 years,
have left only an estimated 250,000 to 350,000 ha (617,763 to 864,868
ac) of production forests in Panama (Gutierrez 2001a in Parker et al.
2004, p. I-10). Additionally, many protected areas in Panama lack
adequate staff and resources to patrol the areas or enforce regulations
(Devenish et al. 2009b, p. 291). In 1986, Panama initiated a national
forest strategy (Plan de Acci[oacute]n Forestal de Panama or PAFPAN)
supported by FAO; however the plan reportedly did not directly tackle
the causes of deforestation. Between 1980 and 1990, concessions for
77,800 ha (192,248 ac) of production forests were awarded to 23
companies, for periods ranging from 2 to 5 years (Parker et al. 2004,
p. II-4). In 1994, a new forestry law was approved, which
[[Page 60018]]
institutionalized forest management. Now, concessions exist only in the
Dari[eacute]n Province (Parker et al. 2004, p. II-4). Between 1992 and
2000, the Dari[eacute]n Province was one of Panama's provinces that
experienced the greatest declines (11.5 percent) in forest cover
(Parker et al. 2004, p. 32). However, there are activities in place to
combat these pressures. For example, a training program exists to
increase capacity in issues such as planning, geographic information
systems, sustainable tourism, trail construction and management for
park staff, community groups, and other stakeholders in the protected
area system.
Dari[eacute]n National Park
Dari[eacute]n National Park extends along about 80 percent of the
Panama-Colombia border and includes part of the Pacific coast. The area
has been under protection since 1972, with the establishment of Alto
Dari[eacute]n Protection Forest. It was declared a national park in
1980. The park is zoned as a strictly protected core zone of over
83,000 ha (205,097 ac). Another zone consists of 180,000 ha (444,789
ac) and contains indigenous Indian populations that have maintained
their traditional way of life and culture. Approximately 8,000 ha
(19,768 ac) is designated for tourism and environmental education, and
the last zone is described as an ``inspection zone'' which is 40-km
(25-mi) wide, and spans the Panama-Colombia border. The Dari[eacute]n
forests are threatened from logging, agriculture expansion, burning,
and hunting and gathering (TNC 2011, pp. 1-2; Monge et al. 2009, p.
68). Other threats to forest in the region include the development of
projects such as dams and highways (Parker et al. 2004, pp. II-7-II-8).
Since 1986, the Asociaci[oacute]n Nacional para la Conservacion de
la Naturaleza (ANCON) has been actively involved in conservation of the
park in conjunction with INRENARE, the World Wildlife Fund, and other
conservation entities. In 1995, a biodiversity conservation project was
initiated. The project's goal was to involve local communities in
conservation and sustainable use activities, and was funded by the
United Nations Environment Programme (UNEP) and the Global Environment
Facility. The Nature Conservancy (TNC) is also active in conservation
efforts in this area through its Parks in Peril program (TNC 2011, pp.
1-2).
Panama has also initiated reforestation efforts. For example,
beginning in the 1960s, Panama began to plant Pinus caribaea (pine
species) in degraded areas of the Cordillera of the central region.
Additionally, in 1992, a law was passed to provide incentives for the
establishment of plantations; however, these were mainly exotic species
(Parker et al. 2004, p. III-6). Panama is now implementing
reforestation and timber production projects that focus on native
species. This initiative is known as the ``Native Species Reforestation
Project'' (Proyecto de Reforestaci[oacute]n con Especies Nativas;
PRORENA) (Schmidt 2009, p. 10). Forestry managers have realized that,
in some cases, native species are better adapted and perform better
than introduced species. Since 2001, the joint Native Species
Reforestation Project between the Smithsonian Tropical Research
Institute and the Yale School of Forestry has conducted ongoing
research on trees native to Panama. The almendro tree, which is vital
to the great green macaw's habitat, has been the subject of research
projects in Panama because of its high commercial value (Schmidt 2009,
p. 17). Despite efforts to reduce deforestation activities, management
problems remain. A study conducted in 2004 suggested that the Forestry
Department needs increased autonomy, funding, and staff, and a more
appropriate mandate (Parker et al. 2004, pp. 10-11). The study
suggested that strengthening the Parks and Wildlife Service through
increased staffing and resources would enable them to protect and
manage protected areas (Parker et al. 2004, pp. 10-11).
In summary, Panama has a suite of environmental laws in place, and
conservation measures are being implemented by the government in
collaboration with some NGOs. However, there is very little information
available about the great green macaw in Panama (Monge et al. 2009, p.
68), and the information indicates that this species continues to face
pressures to its habitat. Despite Panama's participation in
conservation initiatives and Panama's regulatory mechanisms in place,
there are still significant pressures for resources in the great green
macaw's habitat.
International Wildlife Trade (CITES)
The CITES Treaty requires Parties to have adequate legislation in
place for its implementation. A complete discussion on CITES is found
under Factor D for the military macaw. Within the recent past (since
2000), 261 live great green macaws were reported to have been imported
by CITES reporting countries, and none of these live specimens were
reported as wild origin (UNEP-WCMC CITES Trade Database, accessed
December 8, 2011). Under CITES Resolution Conference 8.4 (Rev. CoP15),
and related decisions of the Conference of the Parties, the National
Legislation Project evaluates whether Parties have adequate domestic
legislation to successfully implement the Treaty (CITES 2011a). In
reviewing a country's national legislation, the CITES Secretariat
evaluates factors such as whether or not a Party:
Has domestic laws that prohibit trade contrary to the
requirements of the Convention;
Has penalty provisions in place for illegal trade, and has
designated the responsible Scientific and Management Authorities; and
Provides for seizure of specimens that are illegally
traded or possessed.
The CITES Secretariat determined that the legislations of Colombia,
Costa Rica, Honduras, Nicaragua, and Panama are sufficient to properly
implement the Treaty (https://www.cites.org, SC58 Doc. 18 Annex 1, p.
1). These governments were determined to be in Category 1, which means
they meet all the requirements to implement CITES. Ecuador was
determined to be in Category 2, with a draft plan, but not enacted
(https://www.cites.org, SC59 Document 11, Annex p. 1, accessed December
16, 2011). This means the CITES Secretariat determined that the
legislation of Ecuador meets some, but not all, of the requirements for
implementing CITES. Based on the limited amount of reported
international trade for this species, particularly in wild-caught
specimens, the range countries, including Ecuador, have effectively
controlled legal international trade of this species. Therefore, we
find CITES is an adequate regulatory mechanism.
Summary of Factor D
In the range countries for this species, we recognize that
conservation activities are occurring, and each country has enacted
laws with the intent of protecting its species and habitat. For
example, in 2002, the San Juan--La Selva Biological Corridor, an area
of 60,000 ha (148,263 ac), was implemented to protect the nesting
places and migration flyway of the great green macaw in Costa Rica, as
far as the Nicaragua border, where very little is known about the
species. However, most of the suitable habitat is restricted to
protected areas in clustered locations. Oliveira et al. (2007) found
that forests in conservation units were four times better at protecting
against deforestation than unprotected areas (Oliveira et al. 2007, p.
1,235). Despite regulatory mechanisms established by this species'
range countries and despite the species' existence in areas designated
as protected, this species has experienced
[[Page 60019]]
threats such that its populations are now so small that any pressure
has a more significant effect. Parks, without management, are often
insufficient to adequately protect the species.
The information available with respect to the species' population
numbers is extremely limited in its range countries, and the
populations of this species in these countries all likely range from a
few individuals to a few hundred individuals (Botero-Delgadillo and
P[aacute]ez 2011, p. 91; Monge et al. 2010, p. 22; Monge et al. 2009,
p. 256). The populations are all in relatively disconnected areas. Its
suitable habitat has been severely constricted due to deforestation. In
all of the range countries, there is clear evidence of threats to this
species due to activities such as habitat destruction and degradation,
and poaching, and there is decreased viability due to small population
sizes, despite the laws and regulatory mechanisms in place. Given that
the species' habitat continues to be fragmented and degraded, it is
unlikely that any conservation measures are adequately mitigating the
factors currently acting on the species.
Based on the best available information, despite protections in
place by the respective governments, we find that the existing
regulatory mechanisms are either inadequate or inadequately enforced to
protect the species or to mitigate ongoing habitat loss and
degradation, poaching, and severe population declines. Habitat
conservation measures within these range countries do not appear to be
sufficient to adequately mitigate future habitat losses. This is due to
a suite of factors, such as high rates of poverty in the range of the
great green macaw and subsequent pressures for resources, and
conflicting management goals (such as economic development and
protection of its resources) of its range countries. Therefore, we find
that the existing regulatory mechanisms are inadequate to mitigate the
current threats to the continued existence of the great green macaw
throughout its range.
E. Other Natural or Manmade Factors Affecting Its Continued Existence
Small Population Size and Stochastic Events
There have been few quantitative studies of great green macaw
populations (Botero-Delgadillo and P[aacute]ez 2011, p. 91; Monge et
al. 2010, p. 12; Monge et al. 2009.). In 2009, the combined estimate
for Costa Rica and Nicaragua was 871 individuals (Monge et al. 2010, p.
21), and the estimate for Ecuador was fewer than 100 (Horstman 2011, p.
17). There are no current population estimates for Panama, Honduras,
and Colombia, but the global population is believed to be fewer than
3,700 individuals (Monge et al. 2009, pp. 68, 79, 213). Small,
declining populations can be especially vulnerable to environmental
disturbances such as habitat loss (Harris and Pimm 2008, pp. 163-164;
O'Grady 2004, pp. 513-514; Brooks et al. 1999, pp. 1,146-1,147). In
Costa Rica, the great green macaw has been eliminated from
approximately 90 percent of its former range, and one estimate
indicated that there were only 275 birds remaining in 2010 (Chassot
2010 pers. comm. in Hardman 2011, p. 11). Isolated populations are more
likely to decline than those that are not isolated (Davies et al. 2000,
p. 1,456), as evidenced by the Ecuadorian population. Additionally, the
great green macaw's restricted range, combined with its small
population size and low prospect for dispersal (Chosset et al. 2004, p.
32), makes the species particularly vulnerable to the threat of any
adverse natural (e.g., genetic, demographic, or stochastic) and manmade
(e.g., habitat alteration and destruction) events that could destroy
individuals and their habitats.
The government of Costa Rica, in cooperation with Zoo Ave Wildlife
Conservation Park, located in Garita de Alajuela, has participated in a
captive bird breeding program (Herrero 2006, pp. 2-3) since 1994. Some
of the birds produced have been released in protected areas. However,
captive breeding is a controversial issue, mainly due to the
reintroduction of individuals. One of the concerns is that the
reintroduced birds introduce infectious diseases (which may be in
dormant phase for a period of time) into the wild (Brightsmith et al.
2006 in Herrero 2006, pp. 2-3).
There are multiple features of this species' biology and life
history that affect its ability to respond to habitat loss and
alteration, as well as to stochastic environmental events. Due to its
current restricted distribution and habitat requirements, stochastic
events could further isolate individuals. An example of a stochastic
event impacting the species occurred in 2010, and the death of several
nestlings was recorded (Chosset and Arias 2010, p. 15). One nestling
fell out of a tree, and, in another case, a branch fell on a nestling
while it was actually in the nest and it died (Chosset and Arias 2010,
p. 15). Losses such as these can have a significant effect on the
population. Additionally, limited available suitable habitat makes it
difficult for the species to recolonize isolated habitat patches, which
presently exist in a highly fragmented state. This, in combination with
the species' nutritional needs, results in the species requiring large
home ranges.
Border Conflict
One of the difficulties in the conservation of this species that
may not be readily apparent is border conflict. For example, at the
border of Nicaragua and Costa Rica, despite cooperation efforts;
conflict continues (U.S. Department of State 2012, unpaginated; Berrios
2004, entire). The Nicaraguan-Costa Rican border is one of the most
conflict-heavy frontiers in Central America (Lopez and Jimenez 2007, p.
21). Migration issues, navigation rights in border rivers, border
delineation, and cultural differences all affect these countries'
relations (Lopez and Jimenez 2007, p. 21). Additionally, this area has
historically experienced exploitation of its natural resources. Since
the beginning of last century, foreign companies have engaged in
logging, rubber extraction, and mining (Lopez and Jimenez 2007, pp. 24-
25). After these resources were depleted and these activities were no
longer profitable, some companies left, leaving behind harmful
environmental impacts (Lopez and Jimenez 2007, pp. 24-25). These
activities have resulted in polluted rivers, high levels of
sedimentation in coastal lagoons, and deforested areas (Lopez and
Jimenez 2007, pp. 24-25). These activities all subsequently affect the
habitat of the great green macaw.
Deforestation in Nicaragua has a complex history. After a civil war
throughout the 1980s, land tenure policies inadvertently encouraged
farming techniques that led to deforestation, soil erosion, and general
land degradation (Sinreich 2009, p. 11). Later, during the 1990s,
COHDEFOR opened up timber extraction opportunities to local community
organizations, mainly cooperatives, to help mitigate the economic
situation for local people. Licenses allowed the use of fallen wood and
timber extraction for sale at local markets. However, a study conducted
between 1998 and 2000 found that local groups had extracted an enormous
amount of timber and there was no monitoring (Col[iacute]ndres and
Rub[iacute] 2002). Although the government offered support to
communities in its border regions during the period of 1994-1999,
tensions continue to affect the Bosawas region of Nicaragua, one of the
areas believed to contain a great green macaw population (Lopez and
Jim[eacute]nez 2007, p. 26). Land rights disputes continue to
[[Page 60020]]
occur in Bosawas, and land use rights are often unclear. Although the
Government of Nicaragua is attempting to manage these issues
(Pellegrini 2011, p. 21), conflict and practices that degrade the great
green macaw's habitat persist both in the Bosawas Reserve and the
Indio-Ma[iacute]z Biological Reserve.
Climate Change
Our analysis under the ESA includes consideration of ongoing and
projected changes in climate (see discussion under the military macaw).
The 2008 workshop in Costa Rica addressed environmental disasters in
the evaluation and assessment of the great green macaw, although
climate change was not specifically addressed. Researchers describe
environmental disasters as events that occur infrequently but that can
drastically affect reproduction or survival. Monge et al. reported that
in Costa Rica, the number of active nests in 2000 was well below the
average of other years. The researchers linked this with the strong El
Ni[ntilde]o event that occurred during 1997-1998 (Monge et al. 2009, p.
149). The researchers stated that in the last 50 years there were two
major El Ni[ntilde]o events, and, therefore, one would expect that in
100 years there would be four events of this nature, which could
subsequently reduce reproduction by 30 percent (Monge et al. 2009, p.
149). However, this correlation between the low number of active nests
and the El Ni[ntilde]o event is not strongly supported, nor do we have
supporting evidence that this is directly related to climate change. We
are not aware of any information that indicates that climate change
threatens the continued existence of the great green macaw.
Summary of Factor E
A species may be affected by more than one threat. Impacts
typically operate synergistically, and are particularly evident when
small populations of a species are decreasing. Initial effects of one
threat factor can exacerbate the effects of other threat factors
(Laurance and Useche 2009, p. 1,432; Gilpin and Soul[eacute] 1986, pp.
25-26). Further fragmentation of populations can decrease the fitness
and reproductive potential of the species, which can exacerbate other
threats. Lack of a sufficient number of individuals in a local area or
a decline in their individual or collective fitness may cause a decline
in the population size, even with suitable habitat patches. Within the
preceding review of the five factors, we have identified multiple
threats that have interrelated impacts on this species. Thus, the
species' productivity may be reduced because of any of these threats,
either singularly or in combination. These threats occur at a
sufficient scale such that they are affecting the status of the species
now and in the future.
This species' current range is highly restricted and severely
fragmented. Each breeding pair requires a large home range to meet its
nutritional requirements; it is a large macaw, and its sources of food
are becoming scarcer and farther apart, which requires more energy
consumption to locate. The susceptibility to extirpation of limited-
range species can occur for a variety of reasons, such as when a
species' remaining population is already too small or its distribution
too fragmented such that it may no longer be demographically or
genetically viable. The species' small and declining population size,
reproductive and life-history traits, and highly restricted and
severely fragmented range together increase the species' vulnerability
to any other stressors. Based on the above evaluation, we conclude that
the effects of isolation and its small, declining population size,
combined with the threats of continued fragmentation and isolation of
suitable forest habitats, pose a threat to the great green macaw.
Finding and Status Determination for the Great Green Macaw
Although precise quantitative estimates are not available, the best
available information suggests that populations of great green macaws
have substantially declined, and this species likely persists at
greatly reduced numbers relative to its historical abundance. The
factors that threaten the survival of the great green macaw are: (A)
Habitat destruction, fragmentation, and degradation; (B)
Overutilization via poaching; (D) inadequacy of regulatory mechanisms
to reduce the threats to the species; and (E) small population size and
isolation of remaining populations.
The direct loss of habitat through widespread deforestation and
conversion of primary forests to human settlement and agricultural uses
has led to the fragmentation of habitat throughout the range of the
great green macaw and isolation of the remaining populations. The
species has been locally extirpated in many areas and has experienced a
significant reduction of suitable habitat. The current suitable habitat
in Costa Rica is now less than 10 percent of its original suitable
habitat (Chosset et al. 2004, p. 38). This species exists generally in
small and fragmented populations, and in many cases, the population is
so small that intense monitoring and management of the population is
under way. The San Juan-La Selva Biological Corridor was established to
connect forest patches and join 20 protected areas (Chosset and Arias
2010, p. 5) specifically to preserve habitat for this species.
We have very little information about the species in many parts of
its range (Botero-Delgadillo and P[aacute]ez 2011, p. 91; Monge et al.
2009, p. 68). In 2008, experts from this species' range countries
attended a conference to evaluate the viability of its populations and
its habitat (Monge et al. 2009, entire). In general, they concluded
that populations are viable but they still face threats. The workshop
also addressed goals for the conservation of the species; in some parts
of its range, conservation efforts are intensive. Based on our review
of the best available scientific and commercial information pertaining
to the five factors, the threats to the species are generally
consistent throughout its range. In many of the range countries, its
populations are very small, and specific information about the status
of the species is not available in all countries. However, habitat loss
and degradation is prevalent throughout this species' range; its
suitable habitat has severely contracted, and habitat loss is likely to
continue into the future due to pressures for resources. Poaching is
known to occur within many parts, if not all parts, of its range.
Despite conservation awareness programs, poverty is prevalent within
the range of the species, and the species is quite valuable
commercially, so poaching continues to occur. We do not find that the
effects of current threats acting on the species are being ameliorated
by regulatory mechanisms. Therefore, we find that listing the great
green macaw as endangered is warranted throughout its range, and we
propose to list the great green macaw as endangered under the ESA.
Available Conservation Measures
Conservation measures provided to species listed as endangered or
threatened under the ESA include recognition, requirements for Federal
protection, and prohibitions against certain practices. Recognition
through listing results in public awareness, and encourages and results
in conservation actions by Federal and State governments, private
agencies and interest groups, and individuals.
The ESA and its implementing regulations set forth a series of
general prohibitions and exceptions that apply to all endangered and
threatened wildlife. These prohibitions, at 50 CFR 17.21 and 17.31, in
part, make it illegal for any person subject to the jurisdiction
[[Page 60021]]
of the United States to ``take'' (includes harass, harm, pursue, hunt,
shoot, wound, kill, trap, capture, or to attempt any of these) within
the United States or upon the high seas; import or export; deliver,
receive, carry, transport, or ship in interstate commerce in the course
of commercial activity; or sell or offer for sale in interstate or
foreign commerce any endangered wildlife species. It also is illegal to
possess, sell, deliver, carry, transport, or ship any such wildlife
that has been taken in violation of the ESA. Certain exceptions apply
to agents of the Service and State conservation agencies.
Permits may be issued to carry out otherwise prohibited activities
involving endangered and threatened wildlife species under certain
circumstances. Regulations governing permits for endangered species are
codified at 50 CFR 17.22. With regard to endangered wildlife, a permit
may be issued for the following purposes: For scientific purposes, to
enhance the propagation or survival of the species, and for incidental
take in connection with otherwise lawful activities. For threatened
species, a permit may be issued for the same activities, as well as
zoological exhibition, education, and special purposes consistent with
the ESA.
National Environmental Policy Act (NEPA)
We have determined that environmental assessments and environmental
impact statements, as defined under the authority of the National
Environmental Policy Act of 1969 (42 U.S.C. 4321 et seq.), need not be
prepared in connection with regulations adopted under section 4(a) of
the ESA. We published a notice outlining our reasons for this
determination in the Federal Register on October 25, 1983 (48 FR
49244).
