Previous Federal Action
On January 9, 1975, as directed by the
Act, the Secretary for the Smithsonian
Institution submitted a report to
Congress on potential endangered and
threatened plant species of the United
States (Smithsonian 1975, entire). The
report identified more than 3,000 plant
species as potentially either endangered
or threatened, including Festuca
ligulata (Guadalupe fescue). On July 1,
1975, we published in the Federal
Register (40 FR 27824) our notification
that we considered this report to be a
petition to list the identified plants as
either endangered or threatened under
the Act. The 1975 notice solicited
information from Federal and State
agencies, and the public, on the status
of the species.
On December 15, 1980, we published
a comprehensive notice of review of
native plants (45 FR 82480) that
included Guadalupe fescue as a
Category 2 candidate species. Category 2
candidates were taxa for which
information then in the possession of
the Service indicated that proposing to
list as endangered or threatened species
was possibly appropriate, but for which
sufficient data on biological
vulnerability and threats were not then
available to support proposed rules. We
VerDate Sep<11>2014
15:27 Sep 08, 2016
Jkt 238001
retained the Category 2 status for
Guadalupe fescue in updated notices of
review of vascular plant taxa on
September 27, 1985 (50 FR 39526), and
February 21, 1990 (55 FR 6184). In a
notice of review published on
September 30, 1993 (58 FR 51144), we
revised the status of Guadalupe fescue
to a Category 1 candidate, meaning that
the Service had on file sufficient
information on biological vulnerability
and threat(s) to support a proposal to
list it as an endangered or threatened
species, but that a proposed rule had not
yet been issued because this action was
precluded at that time by other listing
activities. The candidate notice of
review published on February 28, 1996
(61 FR 7596), eliminated categories
within candidate species, and
Guadalupe fescue was included as a
candidate with a listing priority number
of 8. The listing priority number was
revised to 11 on October 25, 1999 (64 FR
57534), based on the commitment of Big
Bend National Park to manage habitat
for the species through a candidate
conservation agreement (CCA). On May
4, 2004 (69 FR 24876), we indicated that
Guadalupe fescue remained a candidate
following a re-submitted petition. We
have retained the candidate status for
Guadalupe fescue, with a listing priority
number of 11, in all subsequent notices
of review (70 FR 24870, May 11, 2005;
71 FR 53756, September 12, 2006; 72 FR

Elsewhere in this issue of the Federal
Register, we propose to designate
critical habitat for Guadalupe fescue
under the Act.
Background
Staff of the Austin Ecological Services
Field Office developed the SSA Report
for Guadalupe fescue, which is an
evaluation of the best available
scientific and commercial data on the
status of the species, including the past,
present, and future threats to this
species and the effect of conservation
measures. The SSA Report and other
materials related to this proposal are
available online at https://

The SSA Report (Service 2016) is
based on a thorough review of the
natural history, habitats, ecology,
populations, and range of Guadalupe
fescue. The SSA Report analyzes
individual, population, and species
requirements; factors affecting the
species’ survival; and current conditions
to assess the species’ current and future
viability in terms of resiliency,
redundancy, and representation. We
define viability as the ability of a
species to maintain populations over a
defined period of time.
Resiliency refers to the population
size necessary to endure stochastic
environmental variation (Shaffer and
Stein 2000, pp. 308–310). Resilient
populations are better able to recover
from losses caused by random variation,
such as fluctuations in recruitment
(demographic stochasticity), variations
in rainfall (environmental stochasticity),
or changes in the frequency of wildfires.
Redundancy refers to the number and
geographic distribution of populations
or sites necessary to endure catastrophic
events (Shaffer and Stein 2000, pp. 308–
310). As defined here, catastrophic
events are rare occurrences, usually of
finite duration, that cause severe
impacts to one or more populations.
Examples of catastrophic events include
tropical storms, floods, prolonged
drought, and unusually intense wildfire.
Species that have multiple resilient
populations distributed over a larger
landscape are more likely to survive
catastrophic events, since not all
populations would be affected.
Representation refers to the genetic
diversity, both within and among
populations, necessary to conserve longterm adaptive capability (Shaffer and
Stein 2000, pp. 307–308). Species with
greater genetic diversity are more able to
adapt to environmental changes and to
colonize new sites.
Summary of Biological Status and
Threats
Guadalupe fescue is a short-lived
perennial grass species found only in a
few high mountains of the Chihuahuan
Desert, west of the Pecos River in Texas
and in the State of Coahuila, Mexico.
These ‘‘sky island’’ habitats are coniferoak woodlands above 1,800 meters (m)
(5,905 feet (ft)) elevation. The species
has been reported in only six sites. It
was first collected in 1931, in the
Guadalupe Mountains, Culberson
County, Texas, and in the Chisos
Mountains, Brewster County, Texas;
these sites are now within Guadalupe
Mountains National Park and Big Bend
National Park, respectively. Guadalupe
fescue was documented near Fraile,
southern Coahuila, in 1941; in the Sierra

la Madera, central Coahuila, in 1977;
and at two sites in the Maderas del
Carmen Mountains of northern Coahuila
in 1973 and 2003. The last three sites
are now within protected natural areas
(‘‘areas naturales protegidas’’ (ANP))
designated by the Mexican federal
government.
In the United States, known
populations of Guadalupe fescue have
experienced significant declines.
Guadalupe fescue was last observed in
the Guadalupe Mountains in 1952; this
population is presumed extirpated.
Researchers from Texas Parks and
Wildlife Department and Big Bend
National Park have quantitatively
monitored plots within the Chisos
Mountains population over a 22-year
period. Our analysis of these data
indicates that the population within the
plots (about 25 to 50 percent of the total
population) has decreased significantly
over time, from a high of 125 and 127
individuals in 1993 and 1994, to 47
individuals in 2013 and 2014. Little
information is available for the known
populations in Mexico. Valdes-Reyna
(2009, pp. 13, 15) confirmed that one
population in the Maderas del Carmen
mountains is extant. This population
had several hundred individuals in
2003 (Big Bend National Park and
Service 2008), and is protected within
ANP Maderas del Carmen. The status of
the other three Coahuilan populations
remains unknown.
To estimate the amount and
distribution of potential Guadalupe
fescue habitat, we created maps of
conifer-oak forests in the Chihuahuan
Desert at elevations greater than 1,800
m. Since larger habitat areas may be
more suitable, we restricted this model
to areas greater than 200 hectares (ha)
(494 acres (ac)). This model reveals that
northern Mexico has 283 areas of
potential habitat totaling 537,998 ha
(over 1.3 million ac), compared to 20
such areas totaling 27,881 ha (68,894 ac)
in Texas. Thus, about 95 percent of the
potential habitat is in Mexico. However,
we do not have information confirming
that any of these areas actually contain
Guadalupe fescue.
Monitoring suggests that the Chisos
Mountains population has decreased in
size; however the data indicate that
survival rates within this monitored
population have increased. These
inverse trends may be explained by a
recruitment rate (establishment of new
individuals) that is too low to sustain
the population. We do not know why
the recruitment rate at the Chisos
population is low. We have no
information about the species’ genetic
viability, within-population and withinspecies genetic differentiation,

chromosome number, or breeding
system. However, since grasses are
wind-pollinated, small, widely-scattered
populations produce few if any seeds
from out-crossing (pollination by
unrelated individuals). Many perennial
grasses, including some Festuca species,
are obligate out-crossers. If Guadalupe
fescue is an obligate out-crosser, the
sparse Chisos population would
produce few seeds; if it is not an
obligate out-crosser, it is probably
highly inbred and may suffer from
inbreeding depression. Although the
minimum viable population (MVP) size
has not yet been calculated for
Guadalupe fescue, we can estimate its
MVP by comparison to species with
similar life histories (i.e., surrogates) for
which MVPs have been calculated,
using the following guideline adapted
from Pavlik (1996, p. 137). Through this
comparison, we estimate that
populations of Guadalupe fescue should
have at least 500 to 1,000 individuals for
long-term population viability (SSA
Report, pp. 17–18).
One factor potentially negatively
affecting the existing population in the
Chisos Mountains is the loss of regular
wildfires. Periodic wildfire and leaf
litter reduction may be necessary for
long-term survival of Guadalupe fescue
populations, although this has not been
investigated. Historically, wildfires
occurred in the vicinity of the Chisos
population at least 10 times between
1770 and 1940 (Moir and Meents 1981,
p. 7; Moir 1982, pp. 90–98; Poole 1989,
p. 8; Camp et al. 2006, pp. 3–6, 14–23,
59–61). However, the last major fire
there was more than 70 years ago, due
to fire suppression within the National
Park. The long absence of fire and the
resulting accumulation of fuels also
increase the risk of more intense
wildfire, which could result in the loss
of the remaining Guadalupe fescue
population in the United States.
Other factors that may affect the
continued survival of Guadalupe fescue
include the genetic and demographic
consequences of small population sizes
and isolation of its known populations;
livestock grazing; trail runoff;
competition from invasive species;
effects of climate change, such as higher
temperatures and changes in the amount
and seasonal pattern of rainfall; and
fungal infection of seeds. Big Bend
National Park has minimized the
potential threat of trampling from
humans and pack animals by restricting
visitors and trail maintenance crews to
established trails and through visitor
outreach.
The Service, Big Bend National Park,
and Guadalupe Mountains National
Park established CCAs for the
PO 00000
Frm 00034
Fmt 4702
Sfmt 4702
Guadalupe fescue in 1998 and 2008.
The objectives of these 10-year
agreements include monitoring and
surveys, seed and live plant banking,
fire and invasive species management,
trail management, staff and visitor
education, establishment of an advisory
team of species experts, and cooperation
with Mexican agencies and researchers
to conserve the known populations of
Guadalupe fescue and search for new
ones. Research objectives include
investigations of fire ecology, habitat
management, genetic structure,
reproductive biology, and
reintroduction.
Based on the best available
information, we know of only two
extant populations of Guadalupe fescue.
The Chisos Mountains population is far
smaller than our estimated MVP level,
and despite protection, appropriate
management, and periodic monitoring
by the National Park Service, it has
declined between 1993 and 2014. The
other extant population, at ANP
Maderas del Carmen in northern
Coahuila, Mexico, may have exceeded
our estimated MVP level as recently as
2003, and the site is managed for natural
resources conservation. Unfortunately,
we possess very little information about
the current status of the species at
Maderas del Carmen and throughout
Mexico. Our analysis revealed that a
large amount of potential habitat exists
in northern Mexico. Thus, it is possible
that other undiscovered populations of
Guadalupe fescue exist in northern
Mexico, and that the overall status of
the species is more secure than we now
know. Nonetheless, the Service has to
make a determination based on the best
available scientific data, which
currently confirm only one extant
population in Mexico.
Determination
Standard for Review
Section 4 of the Act, and its
implementing regulations at 50 CFR part
424, set forth the procedures for adding
species to the Federal Lists of
Endangered and Threatened Wildlife
and Plants. Under section 4(b)(1)(a) of
the Act, the Secretary is to make
endangered or threatened
determinations required by section
4(a)(1) solely on the basis of the best
scientific and commercial data available
to her after conducting a review of the
status of the species and after taking
into account conservation efforts by
States or foreign nations. The standards
for determining whether a species is
endangered or threatened are provided
in section 3 of the Act. An endangered
species is any species that is ‘‘in danger
E:\FR\FM\09SEP1.SGM
09SEP1
Federal Register / Vol. 81, No. 175 / Friday, September 9, 2016 / Proposed Rules
ehiers on DSK5VPTVN1PROD with PROPOSALS
of extinction throughout all or a
significant portion of its range.’’ A
threatened species is any species that is
‘‘likely to become an endangered
species within the foreseeable future
throughout all or a significant portion of
its range.’’ Per section 4(a)(1) of the Act,
in reviewing the status of the species to
determine if it meets the definition of
endangered or of threatened, we
determine whether any species is an
endangered species or a threatened
species because of 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. Our determination must also
consider certain conservation measures
for the species.
The fundamental question before the
Service is whether the species warrants
protection as endangered or threatened
under the Act. To make this
determination, we evaluated the
projections of extinction risk, described
in terms of the condition of current and
future populations and their
distribution (taking into account the risk
factors and their effects on those
populations). For any species, as
population condition declines and
distribution shrinks, the species’
extinction risk increases and overall
viability declines.
Summary of Analysis
We documented in our SSA Report
that only two extant populations of
Guadalupe fescue are currently known.
The only extant population in the
United States, in the Chisos Mountains
at Big Bend National Park, has declined
in abundance since 1993. Only 47
individuals were observed there in
2014, which is far less than an estimated
MVP size of 500 to 1,000 individuals
based on species with similar life
histories. The other extant population,
in the ANP Maderas del Carmen in
Coahuila, had several hundred
individuals in 2003, and was confirmed
extant in 2009 with no population
estimate. Three other historically known
populations in remote areas of Coahuila,
Mexico, have not been monitored in at
least 39 years, and their statuses remain
unknown.
We find that several factors reduce the
viability of Guadalupe fescue,
including: Changes in the wildfire cycle
and vegetation structure of its habitats,
trampling from humans and pack
animals, trail runoff, and competition
VerDate Sep<11>2014
15:27 Sep 08, 2016
Jkt 238001
from invasive species (Factor A); grazing
by livestock and feral animals of
Guadalupe fescue plants (Factor C); and
the genetic and demographic
consequences of small population sizes,
isolation of its known populations, and
potential impacts of climate changes,
such as higher temperatures and
changes in the amount and seasonal
pattern of rainfall (Factor E). Although
trampling, trail runoff, invasive species,
and grazing are likely to be ameliorated
by ongoing and future conservation
efforts on Federal lands in the United
States, the effects of small population
size, geographic isolation, and climate
change are all rangewide threats and
expected to continue into the
foreseeable future. There is limited
information available regarding the
known populations of Guadalupe fescue
in Mexico; however, most of the above
factors are likely to be widespread and
ongoing threats throughout the potential
habitats in Mexico (Service 2016).
The Act defines an endangered
species as any species that is ‘‘in danger
of extinction throughout all or a
significant portion of its range’’ and a
threatened species as any species ‘‘that
is likely to become endangered
throughout all or a significant portion of
its range within the foreseeable future.’’
We find that Guadalupe fescue is
currently in danger of extinction
throughout all of its range, and therefore
warrants a determination that it is an
endangered species. There are only two
known extant populations of Guadalupe
fescue, one each in Texas and in
Coahuila, Mexico. We have no recent
observations of three additional
populations reported from Mexico, and
their statuses are unknown. A second
population reported from the United
States has not been seen in more than
60 years, despite extensive surveys, and
is presumed extirpated. Based on
monitoring conducted in 2013 and
2014, the Chisos Mountains population
in the United States is estimated to have
in the range of about 100 and 200
individuals, well below the estimated
MVP of 500 to 1,000 individuals, and
the monitored population has declined
from 127 individuals in 1993, to 47
individuals in 2014 (Service 2016,
Appendix B). Therefore, this population
is considered to have low resiliency.
The Maderas del Carmen population in
Mexico may have held the estimated
MVP as recently as 2003, but the current
population status is unknown, and thus
the population is considered to have
limited resilience (Service 2016). With
only two known populations, both with
limited resiliency, the species has
extremely low redundancy and
PO 00000
Frm 00035
Fmt 4702
Sfmt 4702
62453
representation. However, if there are
additional extant populations in
Mexico, we would expect the
redundancy and representation of the
species would be greater. Based on the
best available information, therefore, the
species’ overall risk of extinction is such
that we find it meets the definition of an
endangered species. Therefore, on the
basis of the best available scientific and
commercial information, we propose
listing the Guadalupe fescue as an
endangered species in accordance with
sections 3(6) and 4(a)(1) of the Act. We
find that a threatened species status is
not appropriate for Guadalupe fescue
because of the immediacy of threats
facing the species with only two known
populations, one of which is declining
in abundance.
Under the Act and our implementing
regulations, a species may warrant
listing if it is endangered or threatened
throughout all or a significant portion of
its range. We have determined that
Guadalupe fescue is endangered
throughout all of its range, so an
evaluation of any ‘‘significant’’ portion
of the range is unnecessary. See the
Final Policy on Interpretation of the
Phrase ‘‘Significant Portion of Its
Range’’ in the Endangered Species Act’s
Definitions of ‘‘Endangered Species’’
and ‘‘Threatened Species’’ (79 FR
37578; July 1, 2014).
Available Conservation Measures
Conservation measures provided to
species listed as endangered or
threatened species under the Act
include recognition, recovery actions,
requirements for Federal protection, and
prohibitions against certain practices.
Recognition through listing results in
public awareness, as well as
conservation by Federal, State, Tribal,
and local agencies; private
organizations; and individuals. The Act
encourages cooperation with the States
and other countries, and calls for
recovery actions to be carried out for
listed species. The protection required
by Federal agencies and the prohibitions
against certain activities are discussed,
in part, below.
The primary purpose of the Act is the
conservation of endangered and
threatened species and the ecosystems
upon which they depend. The ultimate
goal of such conservation efforts is the
recovery of these listed species, so that
they no longer need the protective
measures of the Act. Subsection 4(f) of
the Act calls for the Service to develop
and implement recovery plans for the
conservation of endangered and
threatened species. The recovery
planning process involves the
identification of actions that are

ehiers on DSK5VPTVN1PROD with PROPOSALS
62454
Federal Register / Vol. 81, No. 175 / Friday, September 9, 2016 / Proposed Rules
necessary to halt or reverse the species’
decline by addressing the threats to its
survival and recovery. The goal of this
process is to restore listed species to a
point where they are secure, selfsustaining, and functioning components
of their ecosystems.
Recovery planning includes the
development of a recovery outline
shortly after a species is listed and
preparation of a draft and final recovery
plan. The recovery outline guides the
immediate implementation of urgent
recovery actions and describes the
process to be used to develop a recovery
plan. Revisions of the plan may be done
to address continuing or new threats to
the species, as new substantive
information becomes available. The
recovery plan also identifies recovery
criteria for review of when a species
may be ready for downlisting or
delisting, and methods for monitoring
recovery progress. Recovery plans also
establish a framework for agencies to
coordinate their recovery efforts and
provide estimates of the cost of
implementing recovery tasks. Recovery
teams (composed of species experts,
Federal and State agencies,
nongovernmental organizations, and
stakeholders) are often established to
develop recovery plans. Should the
Guadalupe fescue be listed as an
endangered or a threatened species in a
final rule, the completed recovery
outline, draft recovery plan, and the
final recovery plan will be available on
our Web site (https://www.fws.gov/
endangered), or from our Austin
Ecological Services Field Office (see FOR
FURTHER INFORMATION CONTACT).
Implementation of recovery actions
generally requires the participation of a
broad range of partners, including other
Federal agencies, States, Tribes,
nongovernmental organizations,
businesses, and private landowners.
Examples of recovery actions include
habitat restoration (e.g., restoration of
native vegetation), research, captive
propagation and reintroduction, and
outreach and education. The recovery of
many listed species cannot be
accomplished solely on Federal lands
because their range may occur primarily
or solely on non-Federal lands. To
achieve recovery of these species
requires cooperative conservation efforts
on private, State, and Tribal lands. If
this species is listed, funding for
recovery actions could be available from
a variety of sources, including Federal
budgets, State programs, and cost share
grants for non-Federal landowners, the
academic community, and
nongovernmental organizations. In
addition, pursuant to section 6 of the
Act, the State of Texas would be eligible
VerDate Sep<11>2014

Jkt 238001
for Federal funds to implement
management actions that promote the
protection or recovery of Guadalupe
fescue. Information on our grant
programs that are available to aid
species recovery can be found at: https://
www.fws.gov/grants.
Although Guadalupe fescue is only
proposed for listing under the Act at
this time, please let us know if you are
interested in participating in recovery
efforts for this species. Additionally, we
invite you to submit any new
information on this species whenever it
becomes available and any information
you may have for recovery planning
purposes (see FOR FURTHER INFORMATION
CONTACT).
Section 7(a) of the Act requires
Federal agencies to evaluate their
actions with respect to any species that
is proposed or listed as an endangered
or threatened species and with respect
to its critical habitat, if any is
designated. Regulations implementing
this interagency cooperation provision
of the Act are codified at 50 CFR part
402. Section 7(a)(4) of the Act requires
Federal agencies to confer with the
Service on any action that is likely to
jeopardize the continued existence of a
species proposed for listing or result in
destruction or adverse modification of
proposed critical habitat. If a species is
listed subsequently, section 7(a)(2) of
the Act requires Federal agencies to
ensure that activities they authorize,
fund, or carry out are not likely to
jeopardize the continued existence of
the species or destroy or adversely
modify its critical habitat. If a Federal
action may affect a listed species or its
critical habitat, the responsible Federal
agency must enter into consultation
with the Service.
Federal agency actions within the
species’ habitat that may require
conference or consultation or both as
described in the preceding paragraph
are limited to the land management
activities by the National Park Service
within Big Bend National Park.
With respect to endangered plants,
prohibitions outlined at 50 CFR 17.61
make it illegal for any person subject to
the jurisdiction of the United States to
import or export, transport in interstate
or foreign commerce in the course of a
commercial activity, sell or offer for sale
in interstate or foreign commerce, or to
remove and reduce to possession any
such plant species from areas under
Federal jurisdiction. In addition, for
endangered plants, the Act prohibits
malicious damage or destruction of any
such species on any area under Federal
jurisdiction, and the removal, cutting,
digging up, or damaging or destroying of
any such species on any other area in
PO 00000
Frm 00036
Fmt 4702
Sfmt 4702
knowing violation of any State law or
regulation, or in the course of any
violation of a State criminal trespass
law. Exceptions to these prohibitions
are outlined in 50 CFR 17.62.
We may issue permits to carry out
otherwise prohibited activities
involving endangered plants under
certain circumstances. Regulations
governing permits are codified at 50
CFR 17.62. With regard to endangered
plants, the Service may issue a permit
authorizing any activity otherwise
prohibited by 50 CFR 17.61 for scientific
purposes or for enhancing the
propagation or survival of endangered
plants.
It is our policy, as published in the
Federal Register on July 1, 1994 (59 FR
34272), to identify to the maximum
extent practicable at the time a species
is listed, those activities that would or
would not constitute a violation of
section 9 of the Act. The intent of this
policy is to increase public awareness of
the effect of a proposed listing on
proposed and ongoing activities within
the range of the species proposed for
listing. Based on the best available
information, the following actions are
unlikely to result in a violation of
section 9, if these activities are carried
out in accordance with existing
regulations and permit requirements;
this list is not comprehensive:
(1) Normal agricultural and
silvicultural practices conducted on
privately owned lands, including
herbicide and pesticide use, which are
carried out in accordance with any
existing regulations, permit and label
requirements, and best management
practices;
(2) Recreation and management at
National Parks that is conducted in
accordance with existing National Park
Service regulations and policies; and
(3) Normal residential landscape
activities.
Based on the best available
information, the following activities
may potentially result in a violation of
section 9 of the Act; this list is not
comprehensive:
(1) Unauthorized damage or collection
of Guadalupe fescue from lands under
Federal jurisdiction;
(2) Destruction or degradation of the
species’ habitat on lands under Federal
jurisdiction, including the intentional
introduction of nonnative organisms
that compete with, consume, or harm
Guadalupe fescue;
(3) Livestock grazing on lands under
Federal jurisdiction; and
(4) Pesticide applications on lands
under Federal jurisdiction in violation
of label restrictions.

Required Determinations
Clarity of the Rule
We are required by Executive Orders
12866 and 12988 and by the
Presidential Memorandum of June 1,
1998, to write all rules in plain
language. This means that each rule we
publish must:
(1) Be logically organized;
(2) Use the active voice to address
readers directly;
(3) Use clear language rather than
jargon;
(4) Be divided into short sections and
sentences; and
(5) Use lists and tables wherever
possible.
If you feel that we have not met these
requirements, send us comments by one
of the methods listed in ADDRESSES. To
better help us revise the rule, your
comments should be as specific as
possible. For example, you should tell
us the numbers of the sections or
paragraphs that are unclearly written,
Scientific name
which sections or sentences are too
long, the sections where you feel lists or
tables would be useful, etc.
National Environmental Policy Act (42
U.S.C. 4321 et seq.)
We have determined that
environmental assessments and
environmental impact statements, as
defined under the authority of the
National Environmental Policy Act
(NEPA; 42 U.S.C. 4321 et seq.), need not
be prepared in connection with listing
a species as an endangered or
threatened species under the
Endangered Species Act. We published
a notice outlining our reasons for this
determination in the Federal Register
on October 25, 1983 (48 FR 49244).

Proposed rule.
We, the U.S. Fish and
Wildlife Service (Service), propose to
designate critical habitat for Festuca
ligulata (Guadalupe fescue) under the
Endangered Species Act of 1973, as
amended (Act). In total, approximately
7,815 acres (3,163 hectares) in Brewster
County, Texas, located entirely in Big
Bend National Park, fall within the
boundaries of the proposed critical
habitat designation. If we finalize this
rule as proposed, it would extend the
Act’s protections to this species’ critical
habitat. We also announce the
availability of a draft economic analysis
(DEA) of the proposed designation of
critical habitat for Guadalupe fescue.

Public Hearing
Section 4(b)(5) of the Act provides for one or more public hearings
on this proposal, if requested. Requests must be received by the date
specified above in DATES. Such requests must be sent to the address
shown in FOR FURTHER INFORMATION CONTACT. We will schedule public
hearings on this proposal, if any are requested, and announce the
dates, times, and places of those hearings, as well as how to obtain
reasonable accommodations, in the Federal Register and local newspapers
at least 15 days before the hearing.
Peer Review
In accordance with our joint policy on peer review published in the
Federal Register on July 1, 1994 (59 FR 34270), we are seeking the
expert opinions of three appropriate and independent specialists
regarding this proposed rule. The purpose of peer review is to ensure
that our listing determination is based on scientifically sound data,
assumptions, and analyses. The peer reviewers have expertise in the
natural history, habitats, distribution, and ecology of Guadalupe
fescue. The peer reviewers are currently reviewing the Species Status
Assessment (SSA Report) for Guadalupe fescue, which will inform our
determination.
Previous Federal Action
On January 9, 1975, as directed by the Act, the Secretary for the
Smithsonian Institution submitted a report to Congress on potential
endangered and threatened plant species of the United States
(Smithsonian 1975, entire). The report identified more than 3,000 plant
species as potentially either endangered or threatened, including
Festuca ligulata (Guadalupe fescue). On July 1, 1975, we published in
the Federal Register (40 FR 27824) our notification that we considered
this report to be a petition to list the identified plants as either
endangered or threatened under the Act. The 1975 notice solicited
information from Federal and State agencies, and the public, on the
status of the species.
On December 15, 1980, we published a comprehensive notice of review
of native plants (45 FR 82480) that included Guadalupe fescue as a
Category 2 candidate species. Category 2 candidates were taxa for which
information then in the possession of the Service indicated that
proposing to list as endangered or threatened species was possibly
appropriate, but for which sufficient data on biological vulnerability
and threats were not then available to support proposed rules. We
retained the Category 2 status for Guadalupe fescue in updated notices
of review of vascular plant taxa on September 27, 1985 (50 FR 39526),
and February 21, 1990 (55 FR 6184). In a notice of review published on
September 30, 1993 (58 FR 51144), we revised the status of Guadalupe
fescue to a Category 1 candidate, meaning that the Service had on file
sufficient information on biological vulnerability and threat(s) to
support a proposal to list it as an endangered or threatened species,
but that a proposed rule had not yet been issued because this action
was precluded at that time by other listing activities. The candidate
notice of review published on February 28, 1996 (61 FR 7596),
eliminated categories within candidate species, and Guadalupe fescue
was included as a candidate with a listing priority number of 8. The
listing priority number was revised to 11 on October 25, 1999 (64 FR
57534), based on the commitment of Big Bend National Park to manage
habitat for the species through a candidate conservation agreement
(CCA). On May 4, 2004 (69 FR 24876), we indicated that Guadalupe fescue
remained a candidate following a re-submitted petition. We have
retained the candidate status for Guadalupe fescue, with a listing
priority number of 11, in all subsequent notices of review (70 FR
24870, May 11, 2005; 71 FR 53756, September 12, 2006; 72 FR 69034,
December 6, 2007; 73 FR 75176, December 10, 2008; 74 FR 57804, November
9, 2009; 75 FR 69222, November 10, 2010; 76 FR 66370, October 26, 2011;
77 FR 69994, November 21, 2012; 78 FR 70104, November 22, 2013; 79 FR
72450, December 5, 2014; 80 FR 80584, December 24, 2015).
Elsewhere in this issue of the Federal Register, we propose to
designate critical habitat for Guadalupe fescue under the Act.
Background
Staff of the Austin Ecological Services Field Office developed the
SSA Report for Guadalupe fescue, which is an evaluation of the best
available scientific and commercial data on the status of the species,
including the past, present, and future threats to this species and the
effect of conservation measures. The SSA Report and other materials
related to this proposal are available online at https://www.regulations.gov, under Docket No. FWS-R2-ES-2016-0099, and on the
Southwest Region Ecological Services Web site at: https://www.fws.gov/southwest/es/AustinTexas/ESA_Our_species.html.
The SSA Report (Service 2016) is based on a thorough review of the
natural history, habitats, ecology, populations, and range of Guadalupe
fescue. The SSA Report analyzes individual, population, and species
requirements; factors affecting the species' survival; and current
conditions to assess the species' current and future viability in terms
of resiliency, redundancy, and representation. We define viability as
the ability of a species to maintain populations over a defined period
of time.
Resiliency refers to the population size necessary to endure
stochastic environmental variation (Shaffer and Stein 2000, pp. 308-
310). Resilient populations are better able to recover from losses
caused by random variation, such as fluctuations in recruitment
(demographic stochasticity), variations in rainfall (environmental
stochasticity), or changes in the frequency of wildfires.
Redundancy refers to the number and geographic distribution of
populations or sites necessary to endure catastrophic events (Shaffer
and Stein 2000, pp. 308-310). As defined here, catastrophic events are
rare occurrences, usually of finite duration, that cause severe impacts
to one or more populations. Examples of catastrophic events include
tropical storms, floods, prolonged drought, and unusually intense
wildfire. Species that have multiple resilient populations distributed
over a larger landscape are more likely to survive catastrophic events,
since not all populations would be affected.
Representation refers to the genetic diversity, both within and
among populations, necessary to conserve long-term adaptive capability
(Shaffer and Stein 2000, pp. 307-308). Species with greater genetic
diversity are more able to adapt to environmental changes and to
colonize new sites.
Summary of Biological Status and Threats
Guadalupe fescue is a short-lived perennial grass species found
only in a few high mountains of the Chihuahuan Desert, west of the
Pecos River in Texas and in the State of Coahuila, Mexico. These ``sky
island'' habitats are conifer-oak woodlands above 1,800 meters (m)
(5,905 feet (ft)) elevation. The species has been reported in only six
sites. It was first collected in 1931, in the Guadalupe Mountains,
Culberson County, Texas, and in the Chisos Mountains, Brewster County,
Texas; these sites are now within Guadalupe Mountains National Park and
Big Bend National Park, respectively. Guadalupe fescue was documented
near Fraile, southern Coahuila, in 1941; in the Sierra
[[Page 62452]]
la Madera, central Coahuila, in 1977; and at two sites in the Maderas
del Carmen Mountains of northern Coahuila in 1973 and 2003. The last
three sites are now within protected natural areas (``areas naturales
protegidas'' (ANP)) designated by the Mexican federal government.
In the United States, known populations of Guadalupe fescue have
experienced significant declines. Guadalupe fescue was last observed in
the Guadalupe Mountains in 1952; this population is presumed
extirpated. Researchers from Texas Parks and Wildlife Department and
Big Bend National Park have quantitatively monitored plots within the
Chisos Mountains population over a 22-year period. Our analysis of
these data indicates that the population within the plots (about 25 to
50 percent of the total population) has decreased significantly over
time, from a high of 125 and 127 individuals in 1993 and 1994, to 47
individuals in 2013 and 2014. Little information is available for the
known populations in Mexico. Valdes-Reyna (2009, pp. 13, 15) confirmed
that one population in the Maderas del Carmen mountains is extant. This
population had several hundred individuals in 2003 (Big Bend National
Park and Service 2008), and is protected within ANP Maderas del Carmen.
The status of the other three Coahuilan populations remains unknown.
To estimate the amount and distribution of potential Guadalupe
fescue habitat, we created maps of conifer-oak forests in the
Chihuahuan Desert at elevations greater than 1,800 m. Since larger
habitat areas may be more suitable, we restricted this model to areas
greater than 200 hectares (ha) (494 acres (ac)). This model reveals
that northern Mexico has 283 areas of potential habitat totaling
537,998 ha (over 1.3 million ac), compared to 20 such areas totaling
27,881 ha (68,894 ac) in Texas. Thus, about 95 percent of the potential
habitat is in Mexico. However, we do not have information confirming
that any of these areas actually contain Guadalupe fescue.
Monitoring suggests that the Chisos Mountains population has
decreased in size; however the data indicate that survival rates within
this monitored population have increased. These inverse trends may be
explained by a recruitment rate (establishment of new individuals) that
is too low to sustain the population. We do not know why the
recruitment rate at the Chisos population is low. We have no
information about the species' genetic viability, within-population and
within-species genetic differentiation, chromosome number, or breeding
system. However, since grasses are wind-pollinated, small, widely-
scattered populations produce few if any seeds from out-crossing
(pollination by unrelated individuals). Many perennial grasses,
including some Festuca species, are obligate out-crossers. If Guadalupe
fescue is an obligate out-crosser, the sparse Chisos population would
produce few seeds; if it is not an obligate out-crosser, it is probably
highly inbred and may suffer from inbreeding depression. Although the
minimum viable population (MVP) size has not yet been calculated for
Guadalupe fescue, we can estimate its MVP by comparison to species with
similar life histories (i.e., surrogates) for which MVPs have been
calculated, using the following guideline adapted from Pavlik (1996, p.
137). Through this comparison, we estimate that populations of
Guadalupe fescue should have at least 500 to 1,000 individuals for
long-term population viability (SSA Report, pp. 17-18).
One factor potentially negatively affecting the existing population
in the Chisos Mountains is the loss of regular wildfires. Periodic
wildfire and leaf litter reduction may be necessary for long-term
survival of Guadalupe fescue populations, although this has not been
investigated. Historically, wildfires occurred in the vicinity of the
Chisos population at least 10 times between 1770 and 1940 (Moir and
Meents 1981, p. 7; Moir 1982, pp. 90-98; Poole 1989, p. 8; Camp et al.
2006, pp. 3-6, 14-23, 59-61). However, the last major fire there was
more than 70 years ago, due to fire suppression within the National
Park. The long absence of fire and the resulting accumulation of fuels
also increase the risk of more intense wildfire, which could result in
the loss of the remaining Guadalupe fescue population in the United
States.
Other factors that may affect the continued survival of Guadalupe
fescue include the genetic and demographic consequences of small
population sizes and isolation of its known populations; livestock
grazing; trail runoff; competition from invasive species; effects of
climate change, such as higher temperatures and changes in the amount
and seasonal pattern of rainfall; and fungal infection of seeds. Big
Bend National Park has minimized the potential threat of trampling from
humans and pack animals by restricting visitors and trail maintenance
crews to established trails and through visitor outreach.
The Service, Big Bend National Park, and Guadalupe Mountains
National Park established CCAs for the Guadalupe fescue in 1998 and
2008. The objectives of these 10-year agreements include monitoring and
surveys, seed and live plant banking, fire and invasive species
management, trail management, staff and visitor education,
establishment of an advisory team of species experts, and cooperation
with Mexican agencies and researchers to conserve the known populations
of Guadalupe fescue and search for new ones. Research objectives
include investigations of fire ecology, habitat management, genetic
structure, reproductive biology, and reintroduction.
Based on the best available information, we know of only two extant
populations of Guadalupe fescue. The Chisos Mountains population is far
smaller than our estimated MVP level, and despite protection,
appropriate management, and periodic monitoring by the National Park
Service, it has declined between 1993 and 2014. The other extant
population, at ANP Maderas del Carmen in northern Coahuila, Mexico, may
have exceeded our estimated MVP level as recently as 2003, and the site
is managed for natural resources conservation. Unfortunately, we
possess very little information about the current status of the species
at Maderas del Carmen and throughout Mexico. Our analysis revealed that
a large amount of potential habitat exists in northern Mexico. Thus, it
is possible that other undiscovered populations of Guadalupe fescue
exist in northern Mexico, and that the overall status of the species is
more secure than we now know. Nonetheless, the Service has to make a
determination based on the best available scientific data, which
currently confirm only one extant population in Mexico.
Determination
Standard for Review
Section 4 of the Act, and its implementing regulations at 50 CFR
part 424, set forth the procedures for adding species to the Federal
Lists of Endangered and Threatened Wildlife and Plants. Under section
4(b)(1)(a) of the Act, the Secretary is to make endangered or
threatened determinations required by section 4(a)(1) solely on the
basis of the best scientific and commercial data available to her after
conducting a review of the status of the species and after taking into
account conservation efforts by States or foreign nations. The
standards for determining whether a species is endangered or threatened
are provided in section 3 of the Act. An endangered species is any
species that is ``in danger
[[Page 62453]]
of extinction throughout all or a significant portion of its range.'' A
threatened species is any species that is ``likely to become an
endangered species within the foreseeable future throughout all or a
significant portion of its range.'' Per section 4(a)(1) of the Act, in
reviewing the status of the species to determine if it meets the
definition of endangered or of threatened, we determine whether any
species is an endangered species or a threatened species because of 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. Our determination must also
consider certain conservation measures for the species.
The fundamental question before the Service is whether the species
warrants protection as endangered or threatened under the Act. To make
this determination, we evaluated the projections of extinction risk,
described in terms of the condition of current and future populations
and their distribution (taking into account the risk factors and their
effects on those populations). For any species, as population condition
declines and distribution shrinks, the species' extinction risk
increases and overall viability declines.
Summary of Analysis
We documented in our SSA Report that only two extant populations of
Guadalupe fescue are currently known. The only extant population in the
United States, in the Chisos Mountains at Big Bend National Park, has
declined in abundance since 1993. Only 47 individuals were observed
there in 2014, which is far less than an estimated MVP size of 500 to
1,000 individuals based on species with similar life histories. The
other extant population, in the ANP Maderas del Carmen in Coahuila, had
several hundred individuals in 2003, and was confirmed extant in 2009
with no population estimate. Three other historically known populations
in remote areas of Coahuila, Mexico, have not been monitored in at
least 39 years, and their statuses remain unknown.
We find that several factors reduce the viability of Guadalupe
fescue, including: Changes in the wildfire cycle and vegetation
structure of its habitats, trampling from humans and pack animals,
trail runoff, and competition from invasive species (Factor A); grazing
by livestock and feral animals of Guadalupe fescue plants (Factor C);
and the genetic and demographic consequences of small population sizes,
isolation of its known populations, and potential impacts of climate
changes, such as higher temperatures and changes in the amount and
seasonal pattern of rainfall (Factor E). Although trampling, trail
runoff, invasive species, and grazing are likely to be ameliorated by
ongoing and future conservation efforts on Federal lands in the United
States, the effects of small population size, geographic isolation, and
climate change are all rangewide threats and expected to continue into
the foreseeable future. There is limited information available
regarding the known populations of Guadalupe fescue in Mexico; however,
most of the above factors are likely to be widespread and ongoing
threats throughout the potential habitats in Mexico (Service 2016).
The Act defines an endangered species as any species that is ``in
danger of extinction throughout all or a significant portion of its
range'' and a threatened species as any species ``that is likely to
become endangered throughout all or a significant portion of its range
within the foreseeable future.'' We find that Guadalupe fescue is
currently in danger of extinction throughout all of its range, and
therefore warrants a determination that it is an endangered species.
There are only two known extant populations of Guadalupe fescue, one
each in Texas and in Coahuila, Mexico. We have no recent observations
of three additional populations reported from Mexico, and their
statuses are unknown. A second population reported from the United
States has not been seen in more than 60 years, despite extensive
surveys, and is presumed extirpated. Based on monitoring conducted in
2013 and 2014, the Chisos Mountains population in the United States is
estimated to have in the range of about 100 and 200 individuals, well
below the estimated MVP of 500 to 1,000 individuals, and the monitored
population has declined from 127 individuals in 1993, to 47 individuals
in 2014 (Service 2016, Appendix B). Therefore, this population is
considered to have low resiliency. The Maderas del Carmen population in
Mexico may have held the estimated MVP as recently as 2003, but the
current population status is unknown, and thus the population is
considered to have limited resilience (Service 2016). With only two
known populations, both with limited resiliency, the species has
extremely low redundancy and representation. However, if there are
additional extant populations in Mexico, we would expect the redundancy
and representation of the species would be greater. Based on the best
available information, therefore, the species' overall risk of
extinction is such that we find it meets the definition of an
endangered species. Therefore, on the basis of the best available
scientific and commercial information, we propose listing the Guadalupe
fescue as an endangered species in accordance with sections 3(6) and
4(a)(1) of the Act. We find that a threatened species status is not
appropriate for Guadalupe fescue because of the immediacy of threats
facing the species with only two known populations, one of which is
declining in abundance.
Under the Act and our implementing regulations, a species may
warrant listing if it is endangered or threatened throughout all or a
significant portion of its range. We have determined that Guadalupe
fescue is endangered throughout all of its range, so an evaluation of
any ``significant'' portion of the range is unnecessary. See the Final
Policy on Interpretation of the Phrase ``Significant Portion of Its
Range'' in the Endangered Species Act's Definitions of ``Endangered
Species'' and ``Threatened Species'' (79 FR 37578; July 1, 2014).
Available Conservation Measures
Conservation measures provided to species listed as endangered or
threatened species under the Act include recognition, recovery actions,
requirements for Federal protection, and prohibitions against certain
practices. Recognition through listing results in public awareness, as
well as conservation by Federal, State, Tribal, and local agencies;
private organizations; and individuals. The Act encourages cooperation
with the States and other countries, and calls for recovery actions to
be carried out for listed species. The protection required by Federal
agencies and the prohibitions against certain activities are discussed,
in part, below.
The primary purpose of the Act is the conservation of endangered
and threatened species and the ecosystems upon which they depend. The
ultimate goal of such conservation efforts is the recovery of these
listed species, so that they no longer need the protective measures of
the Act. Subsection 4(f) of the Act calls for the Service to develop
and implement recovery plans for the conservation of endangered and
threatened species. The recovery planning process involves the
identification of actions that are
[[Page 62454]]
necessary to halt or reverse the species' decline by addressing the
threats to its survival and recovery. The goal of this process is to
restore listed species to a point where they are secure, self-
sustaining, and functioning components of their ecosystems.
Recovery planning includes the development of a recovery outline
shortly after a species is listed and preparation of a draft and final
recovery plan. The recovery outline guides the immediate implementation
of urgent recovery actions and describes the process to be used to
develop a recovery plan. Revisions of the plan may be done to address
continuing or new threats to the species, as new substantive
information becomes available. The recovery plan also identifies
recovery criteria for review of when a species may be ready for
downlisting or delisting, and methods for monitoring recovery progress.
Recovery plans also establish a framework for agencies to coordinate
their recovery efforts and provide estimates of the cost of
implementing recovery tasks. Recovery teams (composed of species
experts, Federal and State agencies, nongovernmental organizations, and
stakeholders) are often established to develop recovery plans. Should
the Guadalupe fescue be listed as an endangered or a threatened species
in a final rule, the completed recovery outline, draft recovery plan,
and the final recovery plan will be available on our Web site (https://www.fws.gov/endangered), or from our Austin Ecological Services Field
Office (see FOR FURTHER INFORMATION CONTACT).
Implementation of recovery actions generally requires the
participation of a broad range of partners, including other Federal
agencies, States, Tribes, nongovernmental organizations, businesses,
and private landowners. Examples of recovery actions include habitat
restoration (e.g., restoration of native vegetation), research, captive
propagation and reintroduction, and outreach and education. The
recovery of many listed species cannot be accomplished solely on
Federal lands because their range may occur primarily or solely on non-
Federal lands. To achieve recovery of these species requires
cooperative conservation efforts on private, State, and Tribal lands.
If this species is listed, funding for recovery actions could be
available from a variety of sources, including Federal budgets, State
programs, and cost share grants for non-Federal landowners, the
academic community, and nongovernmental organizations. In addition,
pursuant to section 6 of the Act, the State of Texas would be eligible
for Federal funds to implement management actions that promote the
protection or recovery of Guadalupe fescue. Information on our grant
programs that are available to aid species recovery can be found at:
https://www.fws.gov/grants.
Although Guadalupe fescue is only proposed for listing under the
Act at this time, please let us know if you are interested in
participating in recovery efforts for this species. Additionally, we
invite you to submit any new information on this species whenever it
becomes available and any information you may have for recovery
planning purposes (see FOR FURTHER INFORMATION CONTACT).
Section 7(a) of the Act requires Federal agencies to evaluate their
actions with respect to any species that is proposed or listed as an
endangered or threatened species and with respect to its critical
habitat, if any is designated. Regulations implementing this
interagency cooperation provision of the Act are codified at 50 CFR
part 402. Section 7(a)(4) of the Act requires Federal agencies to
confer with the Service on any action that is likely to jeopardize the
continued existence of a species proposed for listing or result in
destruction or adverse modification of proposed critical habitat. If a
species is listed subsequently, section 7(a)(2) of the Act requires
Federal agencies to ensure that activities they authorize, fund, or
carry out are not likely to jeopardize the continued existence of the
species or destroy or adversely modify its critical habitat. If a
Federal action may affect a listed species or its critical habitat, the
responsible Federal agency must enter into consultation with the
Service.
Federal agency actions within the species' habitat that may require
conference or consultation or both as described in the preceding
paragraph are limited to the land management activities by the National
Park Service within Big Bend National Park.
With respect to endangered plants, prohibitions outlined at 50 CFR
17.61 make it illegal for any person subject to the jurisdiction of the
United States to import or export, transport in interstate or foreign
commerce in the course of a commercial activity, sell or offer for sale
in interstate or foreign commerce, or to remove and reduce to
possession any such plant species from areas under Federal
jurisdiction. In addition, for endangered plants, the Act prohibits
malicious damage or destruction of any such species on any area under
Federal jurisdiction, and the removal, cutting, digging up, or damaging
or destroying of any such species on any other area in knowing
violation of any State law or regulation, or in the course of any
violation of a State criminal trespass law. Exceptions to these
prohibitions are outlined in 50 CFR 17.62.
We may issue permits to carry out otherwise prohibited activities
involving endangered plants under certain circumstances. Regulations
governing permits are codified at 50 CFR 17.62. With regard to
endangered plants, the Service may issue a permit authorizing any
activity otherwise prohibited by 50 CFR 17.61 for scientific purposes
or for enhancing the propagation or survival of endangered plants.
It is our policy, as published in the Federal Register on July 1,
1994 (59 FR 34272), to identify to the maximum extent practicable at
the time a species is listed, those activities that would or would not
constitute a violation of section 9 of the Act. The intent of this
policy is to increase public awareness of the effect of a proposed
listing on proposed and ongoing activities within the range of the
species proposed for listing. Based on the best available information,
the following actions are unlikely to result in a violation of section
9, if these activities are carried out in accordance with existing
regulations and permit requirements; this list is not comprehensive:
(1) Normal agricultural and silvicultural practices conducted on
privately owned lands, including herbicide and pesticide use, which are
carried out in accordance with any existing regulations, permit and
label requirements, and best management practices;
(2) Recreation and management at National Parks that is conducted
in accordance with existing National Park Service regulations and
policies; and
(3) Normal residential landscape activities.
Based on the best available information, the following activities
may potentially result in a violation of section 9 of the Act; this
list is not comprehensive:
(1) Unauthorized damage or collection of Guadalupe fescue from
lands under Federal jurisdiction;
(2) Destruction or degradation of the species' habitat on lands
under Federal jurisdiction, including the intentional introduction of
nonnative organisms that compete with, consume, or harm Guadalupe
fescue;
(3) Livestock grazing on lands under Federal jurisdiction; and
(4) Pesticide applications on lands under Federal jurisdiction in
violation of label restrictions.
[[Page 62455]]
Questions regarding whether specific activities would constitute a
violation of section 9 of the Act should be directed to the Austin
Ecological Services Field Office (see FOR FURTHER INFORMATION CONTACT).
Required Determinations
Clarity of the Rule
We are required by Executive Orders 12866 and 12988 and by the
Presidential Memorandum of June 1, 1998, to write all rules in plain
language. This means that each rule we publish must:
(1) Be logically organized;
(2) Use the active voice to address readers directly;
(3) Use clear language rather than jargon;
(4) Be divided into short sections and sentences; and
(5) Use lists and tables wherever possible.
If you feel that we have not met these requirements, send us comments
by one of the methods listed in ADDRESSES. To better help us revise the
rule, your comments should be as specific as possible. For example, you
should tell us the numbers of the sections or paragraphs that are
unclearly written, which sections or sentences are too long, the
sections where you feel lists or tables would be useful, etc.
National Environmental Policy Act (42 U.S.C. 4321 et seq.)
We have determined that environmental assessments and environmental
impact statements, as defined under the authority of the National
Environmental Policy Act (NEPA; 42 U.S.C. 4321 et seq.), need not be
prepared in connection with listing a species as an endangered or
threatened species under the Endangered Species Act. We published a
notice outlining our reasons for this determination in the Federal
Register on October 25, 1983 (48 FR 49244).
