require that such records be kept for any
vehicles. However, buyers of heavy
vehicles are free to insist that
maintenance records be made available
to them at the time of, and as a
condition of, purchase of such vehicles,
just as buyers of automobiles, light
trucks, and other motor vehicles not
exempt from odometer disclosure
ensure that the odometer disclosure
statement is available at the time of
purchase. Removing the odometer
certification exemption would not
alleviate this concern over maintenance
records, and purchasers have sufficient
market power to mandate records before
they purchase the vehicles in question.
In NHTSA’s experience, there has not
been a significant odometer fraud
problem involving heavy trucks or
buses. The agency receives very few
complaints pertaining to these types of
vehicles. Eliminating the exemption for
these vehicles would impose costs on
state and the sellers of such vehicles
that, in the aggregate, are not
insignificant. Moreover, expenditure of
agency resources on a rulemaking to
eliminate this exemption would divert
those resources from the agency’s
regulatory priorities, which involve
measures that may save numerous of
lives on the nation’s highways.
For the foregoing reasons, the petition
is denied.

AGENCY:
SUMMARY: We, the U.S. Fish and
Wildlife Service (Service), announce a
90-day finding on two petitions to
reclassify the Florida scrub-jay
(Aphelocoma coerulescens) from
threatened to endangered under the
Endangered Species Act of 1973, as
amended (Act). We find the petitions do
not provide substantial scientific
information indicating that
reclassification of the Florida scrub-jay
VerDate Aug<31>2005

Jkt 208001
may be warranted. Therefore, we will
not initiate a further status review in
response to these petitions. However,
the public may submit to us any new
information that becomes available
concerning the status of the species or
threats to it at any time.
DATES: The administrative finding
announced in this document was made
on January 25, 2006.
ADDRESSES: Data, comments,
information, or questions concerning
these petitions should be sent to the
Field Supervisor, Jacksonville
Ecological Services Office, 6620
Southpoint Drive South, Suite 310,
Jacksonville, FL 32216; or by electronic
mail (e-mail) to floridascrubjay@fws.gov.
The petition finding, supporting
information, and comments are
available for public inspection, by
appointment, during normal business
hours at the above address.
FOR FURTHER INFORMATION CONTACT:
David L. Hankla, Field Supervisor, at
the above address (telephone 904/232–
2580; facsimile 904/232–2404).
SUPPLEMENTARY INFORMATION:
Background
Section 4(b)(3)(A) of the Act (16
U.S.C. 1531 et seq.) requires that we
make a finding on whether a petition to
list, delist, or reclassify a species
presents substantial information to
indicate that the petitioned action may
be warranted. To the maximum extent
practicable, we are to make this finding
within 90 days of our receipt of the
petition, and publish our notice of this
finding promptly in the Federal
Register.
This finding summarizes information
included in the petitions and
information available to us at the time
of the petition review. Under section
4(b)(3)(A) of the Act and our regulations
in 50 CFR 424.14(b), our review of a 90day finding is limited to a determination
of whether the information in the
petition meets the ‘‘substantial scientific
information’’ threshold. Our standard
for substantial information with regard
to a 90-day petition finding is ‘‘that
amount of information that would lead
a reasonable person to believe that the
measure proposed in the petition may
be warranted’’ (50 CFR 424.14(b)).
We have to satisfy the Act’s
requirement that we use the best
available science to make our decisions.
However, we do not conduct additional
research at this point, nor do we subject
the petition to rigorous critical review.
Rather, at the 90-day finding stage, we
accept the petitioner’s sources and
characterizations of the information, to
the extent that they appear to be based
PO 00000
Frm 00040
Fmt 4702
Sfmt 4702
on accepted scientific principles (such
as citing published and peer reviewed
articles, or studies done in accordance
with valid methodologies), unless we
have specific information to the
contrary. Our finding considers whether
the petition states on its face a
reasonable case for reclassification.
Thus our 90-day finding expresses no
view as to the ultimate issue of whether
the species should be reclassified.
Petitions
On March 13, 2002, we received a
petition, dated March 13, 2002, from
John A. Fritschie on behalf of the
Partnership for a Sustainable Future of
Brevard County, Florida; Indian River
Audubon Society; Friends of the Scrub;
Sierra Club Turtle Coast Group;
Conradina Chapter of the Florida Native
Plant Society; Sea Turtle Preservation
Society; League of Women Voters of the
Space Coast, Inc.; and Barrier Island
Preservation Association, Inc. (hereafter
referred to as the 2002 petition). The
2002 petition requested that the Florida
scrub-jay be reclassified from threatened
to endangered and that critical habitat
be designated with reclassification. The
2002 petition contained supporting
information regarding the species’
taxonomy and ecology, historical and
current distribution, present status, and
potential causes of decline. We
acknowledged the receipt of the 2002
petition in a letter to Mr. Fritschie,
dated April 12, 2002.
On May 1, 2003, we received a
petition, dated April 22, 2003, from
Brett M. Paben, WildLaw Florida Office,
on behalf of Save Our Big Scrub, Inc.
(hereafter referred to as the 2003
petition). The 2003 petition requested
that the Florida scrub-jay be reclassified
from threatened to endangered and that
critical habitat be designated with
reclassification. The 2003 petition
contained supporting information
regarding the species’ taxonomy and
ecology, historical and current
distribution, present status, and
potential causes of decline. We
acknowledged the receipt of the 2003
petition in a letter to Mr. Brett Paben,
dated June 20, 2003.
On March 14, 2004, several of the
petitioners filed a complaint (Save Our
Big Scrub, Inc. v. Norton, Case No.
6:04cv349–Orl–28KRS) (M.D. Fla.)
alleging our failure to make 90-day and
12-month petition findings on
reclassifying the Florida scrub-jay and
to revise the critical habitat designation.
In a stipulated settlement agreement
adopted by the court on December 20,
2004, we agreed to submit one 90-day
finding for both petitions to the Federal
Register by January 15, 2006, and to
E:\FR\FM\25JAP1.SGM

complete, if applicable, a combined 12month finding for both petitions by
January 15, 2007. A decision on whether
or not to designate critical habitat will
be considered if reclassification is
warranted.
On August 1, 2005, the Service
received two supplements to the 2003
petition (dated July 12, 2005 and July
14, 2005), containing additional
information for our consideration in
making a finding on the 2003 petition.
References to the 2003 petition in the
following discussion includes the
supplements.
Species Information
For more information on the Florida
scrub-jay, please refer to the final listing
rule published in the Federal Register
on June 3, 1987 (52 FR 20715), and the
most recent recovery plan for this
species (see the ADDRESSES or FOR
FURTHER INFORMATION CONTACT sections,
above, for information on how to obtain
a hard or electronic copy of the plan).
The Florida scrub-jay is in the order
Passeriformes and the family Corvidae.
It was considered a subspecies (A. c.
coerulescens) for several decades (AOU
1957). It regained recognition as a full
species (Florida scrub-jay, Aphelocoma
coerulescens) from the American
Ornithologists’ Union (AOU 1995)
because of genetic, morphological, and
behavioral differences from the other
members of this group: The western
scrub-jay (A. californica) and the island
scrub-jay (A. insularis). In this notice,
Florida scrub-jays will be referred to as
scrub-jays.
Scrub-jays are about 25 to 30
centimeters (cm) (10 to 12 inches (in))
long and weigh about 77 grams (3
ounces). They are similar in size and
shape to blue jays (Cyanocitta cristata)
but differ significantly in coloration
(Woolfenden and Fitzpatrick 1996a). It
lacks the crest, conspicuous whitetipped wing and tail feathers, black
barring, and bridle of the blue jay. The
scrub-jay’s head, nape, wings, and tail
are pale blue, and its body is pale gray
on its back and belly. Its throat and
upper breast are lightly striped and
bordered by a pale blue-gray ‘‘bib’’
(Woolfenden and Fitzpatrick 1996a).
Scrub-jays forage mostly on or near
the ground, often along the edges of
natural or man-made openings. They
visually search for food while hopping
or running along the ground beneath the
scrub or by jumping from shrub to
shrub. Insects, particularly orthopterans
(such as locusts, crickets, grasshoppers,
beetles) and lepidopteran (butterfly and
moth) larvae, form most of the animal
diet throughout most of the year
(Woolfenden and Fitzpatrick 1984).

Jkt 208001
Small vertebrates are eaten when
encountered, including frogs and toads,
lizards, snakes, rodents, and some
young birds. Acorns are the principal
plant food (Woolfenden and Fitzpatrick
1984; Fitzpatrick et al. 1991).
Scrub-jays have a social structure that
involves cooperative breeding, a trait
that the other North American species of
scrub-jays do not show (Woolfenden
and Fitzpatrick 1984, 1990). Scrub-jays
live in families ranging from two birds
(a single mated pair) to extended
families of eight adults (Woolfenden
and Fitzpatrick 1984) and one to four
juveniles.
Scrub-jay pairs occupy year-round,
multi-purpose territories (Woolfenden
and Fitzpatrick 1978, 1984; Fitzpatrick
et al. 1991). Territory size averages 9 to
10 hectares (ha) (22 to 25 acres (ac))
(Woolfenden and Fitzpatrick 1990;
Fitzpatrick et al. 1991), with a minimum
size of about 5 ha (12 ac) (Woolfenden
and Fitzpatrick 1984; Fitzpatrick et al.
1991). Persistent breeding populations
of scrub-jays exist only where there are
scrub oaks in sufficient quantity and
form to provide an ample winter acorn
supply, cover from predators, and nest
sites during the spring (Woolfenden and
Fitzpatrick 1996b).
The scrub-jay has specific habitat
needs. It is endemic to peninsular
Florida’s ancient dune ecosystems or
scrubs, which occur on well-drained to
excessively well-drained sandy soils
(Laessle 1958, 1968; Myers 1990;
Fitzpatrick et al. unpubl. data). This
community type is adapted to nutrientpoor soils, periodic drought, and
frequent fires (Abrahamson 1984). Xeric
oak scrub on the Lake Wales Ridge is
predominantly made up of four species
of stunted, low-growing oaks: sand live
oak (Quercus geminata), Chapman oak
(Q. chapmanii), myrtle oak (Q.
myrtifolia), and scrub oak (Q. inopina)
(Myers 1990). In optimal habitat for
scrub-jays, these oaks are 1 to 3 m (3 to
10 ft) high, interspersed with 10 to 50
percent unvegetated, sandy openings,
and a sand pine (Pinus clausa) canopy
of less than 20 percent (Woolfenden and
Fitzpatrick 1991). Trees and dense
herbaceous vegetation are rare. Other
vegetation noted along with the oaks
includes saw palmetto (Serenoa repens),
scrub palmetto (Sabal etonia), and such
woody shrubs as Florida rosemary
(Ceratiola ericoides) and rusty lyonia
(Lyonia ferruginea).
Status and Distribution
The Florida scrub-jay was federally
listed as threatened in June 3, 1987,
primarily because of habitat
fragmentation, degradation, and loss (52
FR 20715). A threatened species is one
PO 00000
Frm 00041
Fmt 4702
Sfmt 4702
4093
that is likely to become an endangered
species within the foreseeable future
throughout all or a significant portion of
its range. Scrub habitats associated with
Florida’s barrier islands, mainland
coasts, and Lake Wales Ridge are some
of the most imperiled natural
communities in the United States, with
estimates of habitat loss since preEuropean settlement times ranging from
70 to more than 80 percent (Woolfenden
and Fitzpatrick 1996a; Fitzpatrick et al.
unpubl. data). Historically, oak scrub
occurred as numerous isolated patches
in peninsular Florida. These patches
were concentrated along both the
Atlantic and Gulf coasts and on the
central ridges of the peninsula (Davis
1967). Today, only relict patches of
xeric oak scrub remain. Fitzpatrick et al.
(1994) believed that fire suppression
was just as responsible as habitat loss in
the decline of the scrub-jay, especially
in the northern third of its range. Cox
(1987) noted local extirpations and
major decreases in numbers of scrubjays and attributed them to the clearing
of scrub for housing and citrus groves.
The greatest population decline had
occurred during the early 1980s with an
estimated 25 to 50 percent reduction in
scrub-jay numbers (Fitzpatrick et al.
1994).
A Statewide scrub-jay census was last
conducted in 1992–1993, at which time
there were an estimated 4,000 pairs of
scrub-jays in 31 counties in Florida
(Fitzpatrick et al. 1994). The scrub-jay
was considered extirpated in 10
counties (Alachua, Broward, Clay, Dade,
Duval, Gilchrist, Hernando, Hendry,
Pinellas, and St. Johns), and was
considered functionally extinct in an
additional 5 counties (Flagler, Hardee,
Levy, Orange, and Putnam), where 10 or
fewer pairs remained. Recent
information indicates that there are at
least 12 to 14 breeding pairs of scrubjays located within Levy County, higher
than previously thought (K. Miller,
FWC, in litt. 7/16/04), and there is at
least one breeding pair of scrub-jays
remaining in Clay County (K. Miller,
FWC, in litt. 7/16/04). A scrub-jay has
been documented in St. Johns County as
recently as 2003 (J.B. Miller, FDEP, in
litt. 5/13/03). In 1992–1993, population
numbers in 21 of the counties were
below 30 or fewer breeding pairs
(Fitzpatrick et al. 1994).
Results from a population viability
analysis indicated that a population of
scrub-jays with fewer than 10 breeding
pairs had a 50 percent probability of
extinction over 100 years (Stith 1999).
Populations with at least 100 pairs had
a 2 to 3 percent chance of extinction.
Results from this population viability
analysis indicated that 3 of 21
E:\FR\FM\25JAP1.SGM
25JAP1
4094
Federal Register / Vol. 71, No. 16 / Wednesday, January 25, 2006 / Proposed Rules
metapopulations identified had enough
breeding pairs to have a low extinction
risk and an estimated 99 percent
probability of survival over 100 years
(Stith 1999).
Threats Analysis
Pursuant to section 4 of the Act, we
may determine whether a species,
subspecies, or distinct population
segment of vertebrate taxa is endangered
or threatened because of any of the
following five factors: (A) Present or
threatened destruction, modification, or
curtailment of habitat or range; (B)
overutilization for commercial,
recreational, scientific, or educational
purposes; (C) disease or predation; (D)
inadequacy of existing regulatory
mechanisms; and (E) other natural or
manmade factors affecting its continued
existence. In making this 90-day
finding, we evaluated whether the
scientific information presented and
referenced in the petitions would lead a
reasonable person to believe that the
species may now meet the definition of
endangered (that is, in danger of
extinction throughout all or a significant
portion of its range) instead of
threatened, and thus reclassification
may be warranted. Our evaluation of
these threats, based on information
provided in the petition and available in
our files, is presented below.
cprice-sewell on PROD1PC66 with PROPOSALS
A. Present or Threatened Destruction,
Modification, or Curtailment of the
Species’ Habitat or Range
Information Provided in the Petitions
The 2003 petition stated that,
historically, scrub habitat occurred as
large contiguous patches, some more
than hundreds of miles (Cox 1987).
Today, only relict patches remain. The
2002 petition stated that most of the
remaining populations of scrub-jays are
vulnerable to extinction due to low
population size and the continued loss,
degradation, and fragmentation of scrub
habitat. The 2002 and 2003 petitions
estimate that the historic range of the
scrub-jay has decreased anywhere from
70 to 90 percent, and that these losses
of habitat equate to equal loss of scrubjays. The 2002 petition contained no
references for the estimate provided, but
the 2003 petition referenced Bergen
(1994). The 2003 petition states that
habitat losses are a result of conversion
to citrus and residential development
(Fernald 1989; Fitzpatrick et al. 1991)
due to Florida’s rapidly growing human
population (USCB 1995, 1997, undated;
FHDC undated). The population growth
and resulting urbanization bring
transportation projects, and any increase
in roads, traffic volumes, and speeds
VerDate Aug<31>2005

Jkt 208001
through scrub-jay habitat are significant
concerns for the continued survival of
the scrub-jay (Noss undated; Mumme et
al. 2000).
As an example of habitat loss, the
2002 and 2003 petitions noted the
vulnerability of the central Brevard
County, Florida, population of scrubjays to human population expansion
there. The petitioners stated that the
area provides the necessary link
between the relatively large southern
population and potentially large
northern population of scrub-jays and
that loss of the link will put the core
population at risk of extinction
(Breininger et al. 2001, 2003). As other
examples of habitat loss, the 2003
petition also expressed concern about
the decline in the scrub-jay populations
in and around the Cedar Key State
Reserve in Levy County (Miller et al.
2003) and scrub-jay population declines
in southwest Florida (Service 1999).
Evaluation of Information in the
Petitions
While Cox (1987) did discuss the
historical range of scrub-jays, he did not
make any statements about how scrub
historically was situated within the state
of Florida, as stated in the 2003 petition.
The 2002 petition did not provide
documentation that the remaining
populations of scrub-jays are more
vulnerable to extinction due to a
reduced population size, and the claim
of continued loss, degradation, and
fragmentation of scrub habitat was
provided with no supporting
documentation.
In the 2002 petition, no reference was
given to support estimates of scrub loss,
but the 2003 petition cited Bergen
(1994). However, Bergen (1994) made no
estimates of scrub loss Statewide,
because his work dealt only with
Brevard County, Florida. Within
Brevard County, however, Bergen (1994)
estimated that 68.8 percent of scrub
habitat was lost between 1943 and 1991.
Bergen (1994) does not provide an
estimate of the amount of scrub lost in
Brevard County between 1987 (the year
that the scrub-jay was listed as
threatened) and 1991, the year of the
most recent information utilized in his
review. Other studies report that the
majority of the habitat loss occurred
prior to 1987 and was one of the reasons
the scrub-jay was listed as threatened.
Cox (1987) relayed a 1980 report that
the number of scrub-jays in Brevard
County had declined sharply since
1955. Further, Fitzpatrick et al. (1994)
report that the greatest population
decline had occurred during the early
1980s with an estimated 25 to 50
percent reduction in scrub-jay numbers.
PO 00000
Frm 00042
Fmt 4702
Sfmt 4702
The petition also stated that the scrub
habitat rangewide has been fragmented
by agriculture and commercial and
residential development (Fernald 1989;
Fitzpatrick et al. 1991). No substantial
information was presented by the
petitioner that indicates what
proportion of the scrub loss has
occurred since the time of the scrubjays’ listing, nor has the petitioner
provided justification that as a result of
the land-clearing activity, and
destruction and fragmentation of scrub
habitat, the species is now in danger of
extinction throughout all or a significant
portion of its range.
The 2003 petition cites U.S. Census
Bureau and Florida Housing Data
Clearinghouse figures to support its
claim that the extensive loss of scrub-jay
habitat is a result of Florida’s rapidly
growing human population. These data,
however, do not provide an analysis of
whether or not the new development is
occurring in scrub habitat. Further, the
2003 petition acknowledged that a
growing human population alone is not
proof that scrub habitat has been
destroyed. There has been no
substantial information presented by the
petitioner that the growing human
population of Florida is placing the
scrub-jay in danger of extinction
throughout all or a significant portion of
its range.
Both petitions stated that along with
population growth and urbanization
comes an increase in transportation
projects. Roadsides often provide
attractive habitat for scrub-jays to hunt
insects and cache acorns, and scrub-jay
territories often spread across roads
(meaning that the scrub-jays will
frequently cross the roads). The 2003
petition alleged that the construction of
high-speed roads adjacent to scrub
habitat occupied by scrub-jays has been
shown to impact negatively the scrubjay populations living there (Mumme et
al. 2000). However, Mumme et al.’s
work looked at only a small portion of
one high-speed road, so we are unable
to draw conclusions about the
rangewide effect of this threat and
whether the scrub-jay is threatened with
extinction because of it.
As examples of loss of scrub habitat
and scrub-jay populations since the
species was listed in 1987, the 2002 and
2003 petitions discuss in detail human
impacts to scrub-jay habitat serving as
critical connectors between
metapopulations in central Brevard
County, Florida (Breininger et al. 2001,
2003). However, Breininger et al.’s
(2001, 2003) work only focused on the
non-Federal lands in Brevard and a
small portion of Indian River County.
Regarding the risk of extinction for this
E:\FR\FM\25JAP1.SGM
25JAP1
cprice-sewell on PROD1PC66 with PROPOSALS
Federal Register / Vol. 71, No. 16 / Wednesday, January 25, 2006 / Proposed Rules
portion of the range, Breininger et al.
(2001) acknowledges that their ‘‘ideas
about population dynamics are untested
and insufficient data on edge effects,
density dependence, and
metapopulation dynamics provide
much uncertainty.’’ The 2003 petition
also raised concerns about loss of scrub
habitat and scrub-jays in the area in and
around Cedar Key State Reserve (Miller
et al. 2003) and the scrub-jay population
declines in southwest Florida (FWS
1999). While we acknowledge that some
scrub-jay populations have declined, the
petitioners have not provided
substantial information indicating that
the species is now in danger of
extinction throughout all or a significant
portion of the range.
While a variety of activities that affect
scrub habitat are occurring in Florida
(such as agriculture and development
(Cox 1987; Fernald 1989; Fitzpatrick et
al. 1991; Bergen 1994; Mumme et al.
2000; Breininger et al. 2001, 2003;
Miller et al. 2003)), the petitions do not
provide substantial information that
these activities, either singly or in
combination, may be destroying or
modifying the Florida scrub-jay’s habitat
to the extent that the species is now in
danger of extinction throughout all or a
significant portion of the species’ range.
Also, with some exceptions, the
petitions fail to provide scientific
documentation to demonstrate that the
areas where habitat loss has occurred
are also the areas where scrub-jay
populations occur.
Although the limited amount of scrub
habitat in Florida makes this species
vulnerable to additional habitat loss and
fragmentation, the petitions do not
address what the effects of these
changes have been on scrub-jay
population numbers across the range of
the species since the time the species
was listed. Based on the preceding
discussion, we do not believe that
substantial information has been
presented by the petitioners indicating
that the present or threatened
destruction, modification, or
curtailment of habitat or range may,
either singularly or in combination with
other factors, rise to the level at which
the scrub-jay is now in danger of
extinction throughout all or a significant
portion of its range and should be
reclassified from threatened to
endangered status.
B. Overutilization for Commercial,
Recreational, Scientific, or Educational
Purposes
Information Provided in the Petitions
The petitions cited the original listing
rule (52 FR 20715) as evidence that
VerDate Aug<31>2005
15:04 Jan 24, 2006
Jkt 208001
malicious shooting of the birds by
vandals continues to pose a threat to the
scrub-jay.
Evaluation of Information in the
Petitions
The information presented is not
different from that addressed in the
original listing rule and the petitioners
did not present any information about
how this threat has affected population
viability. Therefore, the petitions did
not present substantial information
indicating that the scrub-jay may now
be in danger of extinction throughout all
or a significant portion of its range as a
result of malicious shooting by vandals.
C. Disease or Predation
Information Provided in the Petitions
The 2003 petition stated that scrub-jay
populations are affected by the
frequency and severity of catastrophic
mortalities (Fitzpatrick et al. unpubl.
data) and that epidemic disease is the
only known catastrophe that affects
scrub-jay populations (Fitzpatrick et al.
1991). Both petitions expressed concern
for the arrival of West Nile virus in
Florida and its potential negative
impacts on scrub-jays, since scrub-jays
are in the same family (Corvidae) as are
blue jays, American crows, fish crows,
and Western scrub-jay; all of these
species have been negatively affected by
West Nile virus (Root 1996; Allison
2001; CDC undated; USGS 2003). In
addition, the 2003 petition expressed
concern for scrub-jays’ vulnerability to
predation from domestic animals,
particularly feral cats (Fitzpatrick et al.
unpubl. data; FWC 2001; ABC undated).
Evaluation of Information in the
Petitions
We acknowledge the vulnerability of
scrub-jays to catastrophic mortalities
(Woolfenden and Fitzpatrick 1984;
Breininger et al. 1999; Stevens and
Hardesty 1999; Fitzpatrick et al. unpubl.
data), especially that resulting from
epidemic disease (Woolfenden and
Fitzpatrick 1984; Fitzpatrick et al. 1991;
Breininger et al. 1999; Stevens and
Hardesty 1999; Breininger et al. 2001,
2003). The arrival of the West Nile virus
in Florida in 2001 (Stark and Kazanis
2001; Wallace 2001; Breininger et al.
2001, 2003) is of particular concern
because of the scrub-jay’s close familial
relationship to other species which have
been negatively impacted by this virus
(CDC undated), even though it has not
been confirmed that scrub-jays have
been affected in Florida (Stark and
Kazanis 2001; Collins et al. 2002, 2003;
Rivers et al. 2004). Local die-offs of
scrub-jays have been reported since the
PO 00000
Frm 00043
Fmt 4702
Sfmt 4702
4095
arrival of West Nile Virus in Florida,
with the causes not yet determined
(Breininger et al. 2001, 2003). The
petitioners have presented no
substantial information that the scrubjay may now be in danger of extinction
throughout all or a significant portion of
its range as a result of the arrival of West
Nile virus in Florida.
Scrub-jays are vulnerable to predation
by feral and domestic cats, as alleged in
the petitions (Fitzpatrick et al. 1991;
Bowman and Averill 1993; Bergen 1994;
Breininger et al. 1995, 2001;
Woolfenden and Fitzpatrick 1996a,
1996b; Breininger 1999; Toland 1999;
Christman 2000). These references,
however, do not discuss the extent of
the threat by feral and domestic cats to
scrub-jays. Woolfenden and Fitzpatrick
(1996b) state that in suburban habitats,
house cats are ‘‘important’’ predators to
young and adult scrub-jays. Fitzpatrick
et al. (1991) suspect that domestic cats
supported by human food offerings
could eliminate a small local population
of scrub-jays, but there has not been any
quantitative work done on this issue to
date. Thus, the petitioner did not
provide substantial information that
such predation has placed the scrub-jay
in danger of extinction throughout all or
a significant portion of its range.
D. Inadequacy of Existing Regulatory
Mechanisms
Information Provided in the Petitions
Service Regulatory Process
Both petitions claim that, because
critical habitat has not been designated
for the scrub-jay, the section 7
consultation process of the Act does not
consider impacts to unoccupied suitable
habitat and the loss of both occupied
and adjacent unoccupied suitable
habitat (Service 2002a cited in the 2002
petition; FEAR 2003 cited in the 2003
petition). The 2003 petition claims that
without the designation of critical
habitat, section 7 consultation with the
U.S. Army Corps of Engineers (USACE)
has proven to be difficult for the
protection of unoccupied habitat of
listed species (Defenders of Wildlife v.
Ballard, 73F. Supp.2d at 1094 (D. Ariz.
1999), concerning pygmy owls; Fund for
Animals v. Rice, 85 F.3d 535 (11th Cir.
1996), concerning Florida panthers).
The 2003 petition, therefore, asks that
critical habitat be designated for the
scrub-jay.
The 2002 petition contends that the
USACE is failing to consider the
cumulative impact of its actions
(Service 2001b). Both petitions express
concern for the Service regulatory
program regarding scrub-jays (Fritschie
2002, Attachment B; Service 2003), with
E:\FR\FM\25JAP1.SGM
25JAP1
4096
Federal Register / Vol. 71, No. 16 / Wednesday, January 25, 2006 / Proposed Rules
cprice-sewell on PROD1PC66 with PROPOSALS
the 2002 petition citing the Plantation
Point biological opinion as an example
(Service 2001b; Fritschie 2002,
Attachment B). The 2003 petition
contends that the location of incidental
take permits issued between 1994 and
2002 demonstrates that a lot of
development activity is occurring in
scrub-jay habitat without the necessary
permits required by the Act (USCB
1995, 1997; Service 2003). The 2002
petition further cites the failure of the
Service to develop a county-wide
approach to deal with scrub-jay
mitigation as evidence of the
inadequacy of existing regulatory
mechanisms in protecting the scrub-jay
(Service 2001a). The 2003 petition
contends that the Service fails to follow
its own mitigation guidance when
consulting under section 7 of the Act
(Service 1999; 2002b) and that the
Service doesn’t hold local counties
responsible for illegal taking of scrubjays (Service 1991a, 1991b, 1992, 1993,
1998; Brevard County 1996; PSF 1998).
The petitioners believe that, as a result,
local governments do not require
Federal permits prior to issuing local
ones (Service 1994a, 1994b), which
could facilitate unauthorized take of
scrub-jays.
The 2003 petition claims that, despite
Federal agencies’ knowledge of the
presence of scrub-jays on lands they
manage, scrub-jay numbers have
continued to decline on those lands
since the species was listed as
threatened (52 FR 20715). In the Ocala
National Forest, for example, the
petitioner states that there has been a 31
percent decrease in scrub-jays since the
estimate made during the period of 1981
to 1983 (U.S. Forest Service (USFS)
2002; Cox 1987). One reason
hypothesized by the petitioner for the
decline is that naturally-occurring fires
are suppressed at Ocala National Forest
(outside of congressionally designated
wilderness areas) and by the State of
Florida (USFS 1999; F.S. section
590.01).
In addition, both petitions contend
that the scrub-jay recovery plan needs to
be revised and implemented because it
is out-of-date.
State Regulatory Process
The 2003 petition contends that
Florida law does not protect scrub-jays
from habitat destruction, which is the
major cause of the species’ decline in
Florida (F.A.C. 68A–27.004(1)(a); 52 FR
20717). In addition, the 2003 petition
claims that in 1999, the Florida Fish and
Wildlife Conservation Commission
(FWC) adopted a new process for
classifying species as endangered,
threatened, or species of special concern
VerDate Aug<31>2005
15:04 Jan 24, 2006
Jkt 208001
(IUCN 1994); therefore, it is
questionable whether the scrub-jay still
classifies as a threatened species under
the Florida statute. The International
Union for Conservation of Nature and
Natural Resources (IUCN) classifies the
scrub-jay as ‘‘vulnerable’’ (IUCN 2002),
which would be the equivalent of a
‘‘species of special concern’’ for the
purposes of the FWC classification,
meaning that the scrub-jay would
receive less protection if the status is
subsequently adopted by FWC. Such a
designation would allow catastrophic
losses to the scrub-jay population before
it could be classified as threatened by
the FWC.
Evaluation of Information in the
Petitions
Service Regulatory Process
Under the section 7 consultation
process, Federal agencies are required to
consult with us when their actions may
affect a listed species. Therefore,
impacts to unoccupied habitat may not
be considered unless the unoccupied
habitat has been designated as critical
habitat for the species under
consultation. The petitions, therefore,
present a factual statement about the
Act. The 2002 petition cites a letter from
the Service, in which we acknowledge
that there are many areas with
potentially suitable scrub habitat that
have become overgrown due to fire
suppression. Most of these sites are
unoccupied by scrub-jays due to the
unsuitable condition of the site’s
habitat, and therefore, the consultation
requirement is not triggered. The 2003
petition cites court cases that do not
relate specifically to the scrub-jay. The
petitions do not provide substantial
information showing a clear link
between the section 7 process and their
assertion that the species should be
reclassified. We do, however, address
the petitions’ claims regarding threats of
habitat destruction and fragmentation
under Factor A. We also note that
designation of unoccupied areas as
critical habitat would not impose any
requirement that land owners or land
managers not suppress fires or conduct
prescribed burns on that land.
The Service and the USACE have
permitted numerous developments in
central Brevard County and other
portions of the species’ range, as
claimed by the petitioners. These
permits are processed in accordance
with applicable laws, regulations, and
agency policies. The 2002 petition cited
a project for Plantation Point (Service
2002b; Fritschie 2002, Attachment B) as
evidence that development in central
Brevard County that may affect scrub-
PO 00000
Frm 00044
Fmt 4702
Sfmt 4702
jays continues to occur. The court
determined that the biological opinion
for this project followed the provisions
of the Act (U.S. District Court 2002).
Further, the claim raised by the 2002
petition is not different from that
addressed in the 1987 final rule listing
the species, because section 7 of the Act
has not been radically changed since
that time. As for the evidence cited by
the 2003 petition (Service 2003), that 28
incidental take permits had been issued
by the Service for projects involving
scrub-jay habitat between 1994 and
2002 and that additional applications
have been received and processed to
date, this information is factual.
However, cumulative impacts of these
actions are addressed as part of
compliance with the National
Environmental Policy Act (42 U.S.C.
4371 et seq.) and in the individual intraService section 7 consultations
conducted on the actions. The petitions
do not provide substantial information
showing a link between these regulatory
actions and their assertion that the
scrub-jay should be reclassified to
endangered. We do, however, address
the petitions’ claims regarding threats of
habitat destruction and fragmentation
under Factor A.
The Service has a rangewide approach
to scrub-jay mitigation for development
activity, which has been revised most
recently in 2004 (Service 2004). The
2003 petition claims that we fail to
follow our own mitigation guidance for
impacts to scrub-jays, as shown in the
outcome of the Plantation Point project
(Service 1999, 2002b). The mitigation
guidelines referenced (Service 1999) are
written for incidental take permit
actions under section 10(a)(1)(B) of the
Act, which requires that impacts be
avoided, minimized, and mitigated to
the maximum extent practicable. The
project used as an example to
demonstrate our failure to follow the
guidelines, however, was not processed
under the provisions of section 10, but
rather section 7. Under section 7, the
action agency is required only to
minimize impacts; the measures
outlined in the mitigation guidance are
utilized for section 7 subject to the
‘‘ultimate determination of acceptability
by the action agency’’ (Service 2002b,
2004). The petitioners have not
presented substantial information that
indicates that as a result of this
mitigation guidance, the scrub-jay is
now in danger of extinction throughout
all or a significant portion of its range.
All counties in which scrub-jays are
present, as well as many of the local
municipalities, have been advised of
their responsibilities under the Act.
Even though Brevard County did not
E:\FR\FM\25JAP1.SGM
25JAP1
Federal Register / Vol. 71, No. 16 / Wednesday, January 25, 2006 / Proposed Rules
adopt a regional HCP, numerous
individual permit applications have
been reviewed by the Service. The
petition does not provide substantial
information to support their claim that
take is occurring as a result of local
governments that are not requiring
Federal permits. Further, the petition
does not identify a clear link between
the claim and the need to reclassify the
species to endangered status.
The 2003 petition cites the Ocala
National Forest as an example of the
inadequacies of regulatory programs,
citing a 31 percent drop in the number
of scrub-jays from the early 1980s to the
early 2000s. (Cox 1987; USFS 2002). We
contend, however, that the survey
methodologies cited in these two
studies were different from one another
and cannot be compared to demonstrate
a drop in scrub-jay numbers. Further, no
substantial information was presented
by the petitioner that population
declines on Federal lands in Florida are
placing the scrub-jay in danger of
extinction throughout all or a significant
portion of its range.
Finally, both the 2002 and 2003
petitions contend that the scrub-jay
recovery plan is in need of revision.
Recovery plans are not regulatory
documents; therefore, this claim is not
relevant to this factor. Further, the
petitions do not provide substantial
information that as a result of the lack
of revision to the scrub-jay recovery
plan, the scrub-jay is now in danger of
extinction throughout all or a significant
portion of its range. We note, however,
that the recovery plan is being revised.
State Regulatory Process
cprice-sewell on PROD1PC66 with PROPOSALS
The 2003 petition’s contention that
Florida law does not protect scrub-jays
from habitat destruction is not different
from that addressed in the 1987 final
rule. In addition, while the information
that a new process has been adopted by
FWC for classifying species as
endangered, threatened, or species of
special concern is factual, according to
the most recent list of imperiled species
for the State of Florida (FWC 2004), the
scrub-jay is still listed as threatened.
The petition provides no substantial
information that indicates as a result of
the existing State laws, the scrub-jay is
now in danger of extinction throughout
all or a significant portion of its range.
E. Other Natural or Manmade Factors
Affecting the Species Continued
Existence
Information Provided in the Petitions
Both the 2002 and 2003 petitions
claim that the fire regime in scrub
habitat has been altered, which has
VerDate Aug<31>2005
15:04 Jan 24, 2006
Jkt 208001
negatively affected scrub-jays (TNC
2001). Scrub-jay habitat, if not
continuously managed, can quickly
become population sinks for scrub-jays,
creating difficulties for land managers
and negatively impacting scrub-jays
(Breininger and Carter 2003; Breininger
and Oddy 2004). Throughout the
northern portion of the species’ range,
the petitioners attribute population
declines of scrub-jays to scrub
fragmentation and degradation, due
primarily to widespread fire
suppression (Cox et al. 1994). In
addition, the 2003 petition claims that
a previous model for the scrub-jay (Root
1998) may have been too optimistic,
because the possibility that certain
kinds of impacts of environmental noise
(such as loud sounds) on scrub-jays was
ignored (Heino and Sabadell 2003).
Evaluation of Information in the
Petitions
We share opinions provided in both
the 2002 and 2003 petitions regarding
the negative effects to scrub-jays from
fire suppression (Breininger and Carter
2003; Breininger and Oddy 2004).
However, fire suppression was
considered a threat to the scrub-jay
when the species was first listed as
threatened in 1987 (52 FR 20715). The
petitions provided no substantial
information that indicates as a result of
fire suppression, the scrub-jay is now in
danger of extinction throughout all or a
significant portion of its range.
The work presented by Heino and
Sabadell (2003) indicates that ignoring
the effects of environmental noise on
scrub-jays in population viability
analysis can result in serious biases to
a model. However, the petitioner did
not provide substantial information that
by not considering environmental noise,
the scrub-jay is now in danger of
extinction throughout all or a significant
portion of its range.
Finding
We have reviewed the petitions and
literature cited in the petitions, and we
have evaluated that information in
relation to other pertinent literature.
After this review and evaluation, we
find the petitions do not present
substantial scientific information to
indicate that reclassification of the
Florida scrub-jay from threatened to
endangered may be warranted at this
time. Although we will not be
commencing a status review in response
to these petitions, we will continue to
monitor the species’ population status
and trends, potential threats, and
ongoing management actions that might
be important with regard to the

conservation of the scrub-jay across its

We encourage interested parties to
continue to gather data that will assist
with the conservation of the species. If
you wish to provide information

Reclassify the Florida Scrub-Jay From Threatened to Endangered
AGENCY: Fish and Wildlife Service, Interior.
ACTION: Notice of 90-day petition finding.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a
90-day finding on two petitions to reclassify the Florida scrub-jay
(Aphelocoma coerulescens) from threatened to endangered under the
Endangered Species Act of 1973, as amended (Act). We find the petitions
do not provide substantial scientific information indicating that
reclassification of the Florida scrub-jay may be warranted. Therefore,
we will not initiate a further status review in response to these
petitions. However, the public may submit to us any new information
that becomes available concerning the status of the species or threats
to it at any time.
DATES: The administrative finding announced in this document was made
on January 25, 2006.
ADDRESSES: Data, comments, information, or questions concerning these
petitions should be sent to the Field Supervisor, Jacksonville
Ecological Services Office, 6620 Southpoint Drive South, Suite 310,
Jacksonville, FL 32216; or by electronic mail (e-mail) to
floridascrubjay@fws.gov. The petition finding, supporting information,
and comments are available for public inspection, by appointment,
during normal business hours at the above address.
FOR FURTHER INFORMATION CONTACT: David L. Hankla, Field Supervisor, at
the above address (telephone 904/232-2580; facsimile 904/232-2404).
SUPPLEMENTARY INFORMATION:
Background
Section 4(b)(3)(A) of the Act (16 U.S.C. 1531 et seq.) requires
that we make a finding on whether a petition to list, delist, or
reclassify a species presents substantial information to indicate that
the petitioned action may be warranted. To the maximum extent
practicable, we are to make this finding within 90 days of our receipt
of the petition, and publish our notice of this finding promptly in the
Federal Register.
This finding summarizes information included in the petitions and
information available to us at the time of the petition review. Under
section 4(b)(3)(A) of the Act and our regulations in 50 CFR 424.14(b),
our review of a 90-day finding is limited to a determination of whether
the information in the petition meets the ``substantial scientific
information'' threshold. Our standard for substantial information with
regard to a 90-day petition finding is ``that amount of information
that would lead a reasonable person to believe that the measure
proposed in the petition may be warranted'' (50 CFR 424.14(b)).
We have to satisfy the Act's requirement that we use the best
available science to make our decisions. However, we do not conduct
additional research at this point, nor do we subject the petition to
rigorous critical review. Rather, at the 90-day finding stage, we
accept the petitioner's sources and characterizations of the
information, to the extent that they appear to be based on accepted
scientific principles (such as citing published and peer reviewed
articles, or studies done in accordance with valid methodologies),
unless we have specific information to the contrary. Our finding
considers whether the petition states on its face a reasonable case for
reclassification. Thus our 90-day finding expresses no view as to the
ultimate issue of whether the species should be reclassified.
Petitions
On March 13, 2002, we received a petition, dated March 13, 2002,
from John A. Fritschie on behalf of the Partnership for a Sustainable
Future of Brevard County, Florida; Indian River Audubon Society;
Friends of the Scrub; Sierra Club Turtle Coast Group; Conradina Chapter
of the Florida Native Plant Society; Sea Turtle Preservation Society;
League of Women Voters of the Space Coast, Inc.; and Barrier Island
Preservation Association, Inc. (hereafter referred to as the 2002
petition). The 2002 petition requested that the Florida scrub-jay be
reclassified from threatened to endangered and that critical habitat be
designated with reclassification. The 2002 petition contained
supporting information regarding the species' taxonomy and ecology,
historical and current distribution, present status, and potential
causes of decline. We acknowledged the receipt of the 2002 petition in
a letter to Mr. Fritschie, dated April 12, 2002.
On May 1, 2003, we received a petition, dated April 22, 2003, from
Brett M. Paben, WildLaw Florida Office, on behalf of Save Our Big
Scrub, Inc. (hereafter referred to as the 2003 petition). The 2003
petition requested that the Florida scrub-jay be reclassified from
threatened to endangered and that critical habitat be designated with
reclassification. The 2003 petition contained supporting information
regarding the species' taxonomy and ecology, historical and current
distribution, present status, and potential causes of decline. We
acknowledged the receipt of the 2003 petition in a letter to Mr. Brett
Paben, dated June 20, 2003.
On March 14, 2004, several of the petitioners filed a complaint
(Save Our Big Scrub, Inc. v. Norton, Case No. 6:04cv349-Orl-28KRS)
(M.D. Fla.) alleging our failure to make 90-day and 12-month petition
findings on reclassifying the Florida scrub-jay and to revise the
critical habitat designation. In a stipulated settlement agreement
adopted by the court on December 20, 2004, we agreed to submit one 90-
day finding for both petitions to the Federal Register by January 15,
2006, and to
[[Page 4093]]
complete, if applicable, a combined 12-month finding for both petitions
by January 15, 2007. A decision on whether or not to designate critical
habitat will be considered if reclassification is warranted.
On August 1, 2005, the Service received two supplements to the 2003
petition (dated July 12, 2005 and July 14, 2005), containing additional
information for our consideration in making a finding on the 2003
petition. References to the 2003 petition in the following discussion
includes the supplements.
Species Information
For more information on the Florida scrub-jay, please refer to the
final listing rule published in the Federal Register on June 3, 1987
(52 FR 20715), and the most recent recovery plan for this species (see
the ADDRESSES or FOR FURTHER INFORMATION CONTACT sections, above, for
information on how to obtain a hard or electronic copy of the plan).
The Florida scrub-jay is in the order Passeriformes and the family
Corvidae. It was considered a subspecies (A. c. coerulescens) for
several decades (AOU 1957). It regained recognition as a full species
(Florida scrub-jay, Aphelocoma coerulescens) from the American
Ornithologists' Union (AOU 1995) because of genetic, morphological, and
behavioral differences from the other members of this group: The
western scrub-jay (A. californica) and the island scrub-jay (A.
insularis). In this notice, Florida scrub-jays will be referred to as
scrub-jays.
Scrub-jays are about 25 to 30 centimeters (cm) (10 to 12 inches
(in)) long and weigh about 77 grams (3 ounces). They are similar in
size and shape to blue jays (Cyanocitta cristata) but differ
significantly in coloration (Woolfenden and Fitzpatrick 1996a). It
lacks the crest, conspicuous white-tipped wing and tail feathers, black
barring, and bridle of the blue jay. The scrub-jay's head, nape, wings,
and tail are pale blue, and its body is pale gray on its back and
belly. Its throat and upper breast are lightly striped and bordered by
a pale blue-gray ``bib'' (Woolfenden and Fitzpatrick 1996a).
Scrub-jays forage mostly on or near the ground, often along the
edges of natural or man-made openings. They visually search for food
while hopping or running along the ground beneath the scrub or by
jumping from shrub to shrub. Insects, particularly orthopterans (such
as locusts, crickets, grasshoppers, beetles) and lepidopteran
(butterfly and moth) larvae, form most of the animal diet throughout
most of the year (Woolfenden and Fitzpatrick 1984). Small vertebrates
are eaten when encountered, including frogs and toads, lizards, snakes,
rodents, and some young birds. Acorns are the principal plant food
(Woolfenden and Fitzpatrick 1984; Fitzpatrick et al. 1991).
Scrub-jays have a social structure that involves cooperative
breeding, a trait that the other North American species of scrub-jays
do not show (Woolfenden and Fitzpatrick 1984, 1990). Scrub-jays live in
families ranging from two birds (a single mated pair) to extended
families of eight adults (Woolfenden and Fitzpatrick 1984) and one to
four juveniles.
Scrub-jay pairs occupy year-round, multi-purpose territories
(Woolfenden and Fitzpatrick 1978, 1984; Fitzpatrick et al. 1991).
Territory size averages 9 to 10 hectares (ha) (22 to 25 acres (ac))
(Woolfenden and Fitzpatrick 1990; Fitzpatrick et al. 1991), with a
minimum size of about 5 ha (12 ac) (Woolfenden and Fitzpatrick 1984;
Fitzpatrick et al. 1991). Persistent breeding populations of scrub-jays
exist only where there are scrub oaks in sufficient quantity and form
to provide an ample winter acorn supply, cover from predators, and nest
sites during the spring (Woolfenden and Fitzpatrick 1996b).
The scrub-jay has specific habitat needs. It is endemic to
peninsular Florida's ancient dune ecosystems or scrubs, which occur on
well-drained to excessively well-drained sandy soils (Laessle 1958,
1968; Myers 1990; Fitzpatrick et al. unpubl. data). This community type
is adapted to nutrient-poor soils, periodic drought, and frequent fires
(Abrahamson 1984). Xeric oak scrub on the Lake Wales Ridge is
predominantly made up of four species of stunted, low-growing oaks:
sand live oak (Quercus geminata), Chapman oak (Q. chapmanii), myrtle
oak (Q. myrtifolia), and scrub oak (Q. inopina) (Myers 1990). In
optimal habitat for scrub-jays, these oaks are 1 to 3 m (3 to 10 ft)
high, interspersed with 10 to 50 percent unvegetated, sandy openings,
and a sand pine (Pinus clausa) canopy of less than 20 percent
(Woolfenden and Fitzpatrick 1991). Trees and dense herbaceous
vegetation are rare. Other vegetation noted along with the oaks
includes saw palmetto (Serenoa repens), scrub palmetto (Sabal etonia),
and such woody shrubs as Florida rosemary (Ceratiola ericoides) and
rusty lyonia (Lyonia ferruginea).
Status and Distribution
The Florida scrub-jay was federally listed as threatened in June 3,
1987, primarily because of habitat fragmentation, degradation, and loss
(52 FR 20715). A threatened species is one that is likely to become an
endangered species within the foreseeable future throughout all or a
significant portion of its range. Scrub habitats associated with
Florida's barrier islands, mainland coasts, and Lake Wales Ridge are
some of the most imperiled natural communities in the United States,
with estimates of habitat loss since pre-European settlement times
ranging from 70 to more than 80 percent (Woolfenden and Fitzpatrick
1996a; Fitzpatrick et al. unpubl. data). Historically, oak scrub
occurred as numerous isolated patches in peninsular Florida. These
patches were concentrated along both the Atlantic and Gulf coasts and
on the central ridges of the peninsula (Davis 1967). Today, only relict
patches of xeric oak scrub remain. Fitzpatrick et al. (1994) believed
that fire suppression was just as responsible as habitat loss in the
decline of the scrub-jay, especially in the northern third of its
range. Cox (1987) noted local extirpations and major decreases in
numbers of scrub-jays and attributed them to the clearing of scrub for
housing and citrus groves. The greatest population decline had occurred
during the early 1980s with an estimated 25 to 50 percent reduction in
scrub-jay numbers (Fitzpatrick et al. 1994).
A Statewide scrub-jay census was last conducted in 1992-1993, at
which time there were an estimated 4,000 pairs of scrub-jays in 31
counties in Florida (Fitzpatrick et al. 1994). The scrub-jay was
considered extirpated in 10 counties (Alachua, Broward, Clay, Dade,
Duval, Gilchrist, Hernando, Hendry, Pinellas, and St. Johns), and was
considered functionally extinct in an additional 5 counties (Flagler,
Hardee, Levy, Orange, and Putnam), where 10 or fewer pairs remained.
Recent information indicates that there are at least 12 to 14 breeding
pairs of scrub-jays located within Levy County, higher than previously
thought (K. Miller, FWC, in litt. 7/16/04), and there is at least one
breeding pair of scrub-jays remaining in Clay County (K. Miller, FWC,
in litt. 7/16/04). A scrub-jay has been documented in St. Johns County
as recently as 2003 (J.B. Miller, FDEP, in litt. 5/13/03). In 1992-
1993, population numbers in 21 of the counties were below 30 or fewer
breeding pairs (Fitzpatrick et al. 1994).
Results from a population viability analysis indicated that a
population of scrub-jays with fewer than 10 breeding pairs had a 50
percent probability of extinction over 100 years (Stith 1999).
Populations with at least 100 pairs had a 2 to 3 percent chance of
extinction. Results from this population viability analysis indicated
that 3 of 21
[[Page 4094]]
metapopulations identified had enough breeding pairs to have a low
extinction risk and an estimated 99 percent probability of survival
over 100 years (Stith 1999).
Threats Analysis
Pursuant to section 4 of the Act, we may determine whether a
species, subspecies, or distinct population segment of vertebrate taxa
is endangered or threatened because of any of the following five
factors: (A) Present or threatened destruction, modification, or
curtailment of habitat or range; (B) overutilization for commercial,
recreational, scientific, or educational purposes; (C) disease or
predation; (D) inadequacy of existing regulatory mechanisms; and (E)
other natural or manmade factors affecting its continued existence. In
making this 90-day finding, we evaluated whether the scientific
information presented and referenced in the petitions would lead a
reasonable person to believe that the species may now meet the
definition of endangered (that is, in danger of extinction throughout
all or a significant portion of its range) instead of threatened, and
thus reclassification may be warranted. Our evaluation of these
threats, based on information provided in the petition and available in
our files, is presented below.
A. Present or Threatened Destruction, Modification, or Curtailment of
the Species' Habitat or Range
Information Provided in the Petitions
The 2003 petition stated that, historically, scrub habitat occurred
as large contiguous patches, some more than hundreds of miles (Cox
1987). Today, only relict patches remain. The 2002 petition stated that
most of the remaining populations of scrub-jays are vulnerable to
extinction due to low population size and the continued loss,
degradation, and fragmentation of scrub habitat. The 2002 and 2003
petitions estimate that the historic range of the scrub-jay has
decreased anywhere from 70 to 90 percent, and that these losses of
habitat equate to equal loss of scrub-jays. The 2002 petition contained
no references for the estimate provided, but the 2003 petition
referenced Bergen (1994). The 2003 petition states that habitat losses
are a result of conversion to citrus and residential development
(Fernald 1989; Fitzpatrick et al. 1991) due to Florida's rapidly
growing human population (USCB 1995, 1997, undated; FHDC undated). The
population growth and resulting urbanization bring transportation
projects, and any increase in roads, traffic volumes, and speeds
through scrub-jay habitat are significant concerns for the continued
survival of the scrub-jay (Noss undated; Mumme et al. 2000).
As an example of habitat loss, the 2002 and 2003 petitions noted
the vulnerability of the central Brevard County, Florida, population of
scrub-jays to human population expansion there. The petitioners stated
that the area provides the necessary link between the relatively large
southern population and potentially large northern population of scrub-
jays and that loss of the link will put the core population at risk of
extinction (Breininger et al. 2001, 2003). As other examples of habitat
loss, the 2003 petition also expressed concern about the decline in the
scrub-jay populations in and around the Cedar Key State Reserve in Levy
County (Miller et al. 2003) and scrub-jay population declines in
southwest Florida (Service 1999).
Evaluation of Information in the Petitions
While Cox (1987) did discuss the historical range of scrub-jays, he
did not make any statements about how scrub historically was situated
within the state of Florida, as stated in the 2003 petition. The 2002
petition did not provide documentation that the remaining populations
of scrub-jays are more vulnerable to extinction due to a reduced
population size, and the claim of continued loss, degradation, and
fragmentation of scrub habitat was provided with no supporting
documentation.
In the 2002 petition, no reference was given to support estimates
of scrub loss, but the 2003 petition cited Bergen (1994). However,
Bergen (1994) made no estimates of scrub loss Statewide, because his
work dealt only with Brevard County, Florida. Within Brevard County,
however, Bergen (1994) estimated that 68.8 percent of scrub habitat was
lost between 1943 and 1991. Bergen (1994) does not provide an estimate
of the amount of scrub lost in Brevard County between 1987 (the year
that the scrub-jay was listed as threatened) and 1991, the year of the
most recent information utilized in his review. Other studies report
that the majority of the habitat loss occurred prior to 1987 and was
one of the reasons the scrub-jay was listed as threatened. Cox (1987)
relayed a 1980 report that the number of scrub-jays in Brevard County
had declined sharply since 1955. Further, Fitzpatrick et al. (1994)
report that the greatest population decline had occurred during the
early 1980s with an estimated 25 to 50 percent reduction in scrub-jay
numbers. The petition also stated that the scrub habitat rangewide has
been fragmented by agriculture and commercial and residential
development (Fernald 1989; Fitzpatrick et al. 1991). No substantial
information was presented by the petitioner that indicates what
proportion of the scrub loss has occurred since the time of the scrub-
jays' listing, nor has the petitioner provided justification that as a
result of the land-clearing activity, and destruction and fragmentation
of scrub habitat, the species is now in danger of extinction throughout
all or a significant portion of its range.
The 2003 petition cites U.S. Census Bureau and Florida Housing Data
Clearinghouse figures to support its claim that the extensive loss of
scrub-jay habitat is a result of Florida's rapidly growing human
population. These data, however, do not provide an analysis of whether
or not the new development is occurring in scrub habitat. Further, the
2003 petition acknowledged that a growing human population alone is not
proof that scrub habitat has been destroyed. There has been no
substantial information presented by the petitioner that the growing
human population of Florida is placing the scrub-jay in danger of
extinction throughout all or a significant portion of its range.
Both petitions stated that along with population growth and
urbanization comes an increase in transportation projects. Roadsides
often provide attractive habitat for scrub-jays to hunt insects and
cache acorns, and scrub-jay territories often spread across roads
(meaning that the scrub-jays will frequently cross the roads). The 2003
petition alleged that the construction of high-speed roads adjacent to
scrub habitat occupied by scrub-jays has been shown to impact
negatively the scrub-jay populations living there (Mumme et al. 2000).
However, Mumme et al.'s work looked at only a small portion of one
high-speed road, so we are unable to draw conclusions about the
rangewide effect of this threat and whether the scrub-jay is threatened
with extinction because of it.
As examples of loss of scrub habitat and scrub-jay populations
since the species was listed in 1987, the 2002 and 2003 petitions
discuss in detail human impacts to scrub-jay habitat serving as
critical connectors between metapopulations in central Brevard County,
Florida (Breininger et al. 2001, 2003). However, Breininger et al.'s
(2001, 2003) work only focused on the non-Federal lands in Brevard and
a small portion of Indian River County. Regarding the risk of
extinction for this
[[Page 4095]]
portion of the range, Breininger et al. (2001) acknowledges that their
``ideas about population dynamics are untested and insufficient data on
edge effects, density dependence, and metapopulation dynamics provide
much uncertainty.'' The 2003 petition also raised concerns about loss
of scrub habitat and scrub-jays in the area in and around Cedar Key
State Reserve (Miller et al. 2003) and the scrub-jay population
declines in southwest Florida (FWS 1999). While we acknowledge that
some scrub-jay populations have declined, the petitioners have not
provided substantial information indicating that the species is now in
danger of extinction throughout all or a significant portion of the
range.
While a variety of activities that affect scrub habitat are
occurring in Florida (such as agriculture and development (Cox 1987;
Fernald 1989; Fitzpatrick et al. 1991; Bergen 1994; Mumme et al. 2000;
Breininger et al. 2001, 2003; Miller et al. 2003)), the petitions do
not provide substantial information that these activities, either
singly or in combination, may be destroying or modifying the Florida
scrub-jay's habitat to the extent that the species is now in danger of
extinction throughout all or a significant portion of the species'
range. Also, with some exceptions, the petitions fail to provide
scientific documentation to demonstrate that the areas where habitat
loss has occurred are also the areas where scrub-jay populations occur.
Although the limited amount of scrub habitat in Florida makes this
species vulnerable to additional habitat loss and fragmentation, the
petitions do not address what the effects of these changes have been on
scrub-jay population numbers across the range of the species since the
time the species was listed. Based on the preceding discussion, we do
not believe that substantial information has been presented by the
petitioners indicating that the present or threatened destruction,
modification, or curtailment of habitat or range may, either singularly
or in combination with other factors, rise to the level at which the
scrub-jay is now in danger of extinction throughout all or a
significant portion of its range and should be reclassified from
threatened to endangered status.
B. Overutilization for Commercial, Recreational, Scientific, or
Educational Purposes
Information Provided in the Petitions
The petitions cited the original listing rule (52 FR 20715) as
evidence that malicious shooting of the birds by vandals continues to
pose a threat to the scrub-jay.
Evaluation of Information in the Petitions
The information presented is not different from that addressed in
the original listing rule and the petitioners did not present any
information about how this threat has affected population viability.
Therefore, the petitions did not present substantial information
indicating that the scrub-jay may now be in danger of extinction
throughout all or a significant portion of its range as a result of
malicious shooting by vandals.
C. Disease or Predation
Information Provided in the Petitions
The 2003 petition stated that scrub-jay populations are affected by
the frequency and severity of catastrophic mortalities (Fitzpatrick et
al. unpubl. data) and that epidemic disease is the only known
catastrophe that affects scrub-jay populations (Fitzpatrick et al.
1991). Both petitions expressed concern for the arrival of West Nile
virus in Florida and its potential negative impacts on scrub-jays,
since scrub-jays are in the same family (Corvidae) as are blue jays,
American crows, fish crows, and Western scrub-jay; all of these species
have been negatively affected by West Nile virus (Root 1996; Allison
2001; CDC undated; USGS 2003). In addition, the 2003 petition expressed
concern for scrub-jays' vulnerability to predation from domestic
animals, particularly feral cats (Fitzpatrick et al. unpubl. data; FWC
2001; ABC undated).
Evaluation of Information in the Petitions
We acknowledge the vulnerability of scrub-jays to catastrophic
mortalities (Woolfenden and Fitzpatrick 1984; Breininger et al. 1999;
Stevens and Hardesty 1999; Fitzpatrick et al. unpubl. data), especially
that resulting from epidemic disease (Woolfenden and Fitzpatrick 1984;
Fitzpatrick et al. 1991; Breininger et al. 1999; Stevens and Hardesty
1999; Breininger et al. 2001, 2003). The arrival of the West Nile virus
in Florida in 2001 (Stark and Kazanis 2001; Wallace 2001; Breininger et
al. 2001, 2003) is of particular concern because of the scrub-jay's
close familial relationship to other species which have been negatively
impacted by this virus (CDC undated), even though it has not been
confirmed that scrub-jays have been affected in Florida (Stark and
Kazanis 2001; Collins et al. 2002, 2003; Rivers et al. 2004). Local
die-offs of scrub-jays have been reported since the arrival of West
Nile Virus in Florida, with the causes not yet determined (Breininger
et al. 2001, 2003). The petitioners have presented no substantial
information that the scrub-jay may now be in danger of extinction
throughout all or a significant portion of its range as a result of the
arrival of West Nile virus in Florida.
Scrub-jays are vulnerable to predation by feral and domestic cats,
as alleged in the petitions (Fitzpatrick et al. 1991; Bowman and
Averill 1993; Bergen 1994; Breininger et al. 1995, 2001; Woolfenden and
Fitzpatrick 1996a, 1996b; Breininger 1999; Toland 1999; Christman
2000). These references, however, do not discuss the extent of the
threat by feral and domestic cats to scrub-jays. Woolfenden and
Fitzpatrick (1996b) state that in suburban habitats, house cats are
``important'' predators to young and adult scrub-jays. Fitzpatrick et
al. (1991) suspect that domestic cats supported by human food offerings
could eliminate a small local population of scrub-jays, but there has
not been any quantitative work done on this issue to date. Thus, the
petitioner did not provide substantial information that such predation
has placed the scrub-jay in danger of extinction throughout all or a
significant portion of its range.
D. Inadequacy of Existing Regulatory Mechanisms
Information Provided in the Petitions
Service Regulatory Process
Both petitions claim that, because critical habitat has not been
designated for the scrub-jay, the section 7 consultation process of the
Act does not consider impacts to unoccupied suitable habitat and the
loss of both occupied and adjacent unoccupied suitable habitat (Service
2002a cited in the 2002 petition; FEAR 2003 cited in the 2003
petition). The 2003 petition claims that without the designation of
critical habitat, section 7 consultation with the U.S. Army Corps of
Engineers (USACE) has proven to be difficult for the protection of
unoccupied habitat of listed species (Defenders of Wildlife v. Ballard,
73F. Supp.2d at 1094 (D. Ariz. 1999), concerning pygmy owls; Fund for
Animals v. Rice, 85 F.3d 535 (11th Cir. 1996), concerning Florida
panthers). The 2003 petition, therefore, asks that critical habitat be
designated for the scrub-jay.
The 2002 petition contends that the USACE is failing to consider
the cumulative impact of its actions (Service 2001b). Both petitions
express concern for the Service regulatory program regarding scrub-jays
(Fritschie 2002, Attachment B; Service 2003), with
[[Page 4096]]
the 2002 petition citing the Plantation Point biological opinion as an
example (Service 2001b; Fritschie 2002, Attachment B). The 2003
petition contends that the location of incidental take permits issued
between 1994 and 2002 demonstrates that a lot of development activity
is occurring in scrub-jay habitat without the necessary permits
required by the Act (USCB 1995, 1997; Service 2003). The 2002 petition
further cites the failure of the Service to develop a county-wide
approach to deal with scrub-jay mitigation as evidence of the
inadequacy of existing regulatory mechanisms in protecting the scrub-
jay (Service 2001a). The 2003 petition contends that the Service fails
to follow its own mitigation guidance when consulting under section 7
of the Act (Service 1999; 2002b) and that the Service doesn't hold
local counties responsible for illegal taking of scrub-jays (Service
1991a, 1991b, 1992, 1993, 1998; Brevard County 1996; PSF 1998). The
petitioners believe that, as a result, local governments do not require
Federal permits prior to issuing local ones (Service 1994a, 1994b),
which could facilitate unauthorized take of scrub-jays.
The 2003 petition claims that, despite Federal agencies' knowledge
of the presence of scrub-jays on lands they manage, scrub-jay numbers
have continued to decline on those lands since the species was listed
as threatened (52 FR 20715). In the Ocala National Forest, for example,
the petitioner states that there has been a 31 percent decrease in
scrub-jays since the estimate made during the period of 1981 to 1983
(U.S. Forest Service (USFS) 2002; Cox 1987). One reason hypothesized by
the petitioner for the decline is that naturally-occurring fires are
suppressed at Ocala National Forest (outside of congressionally
designated wilderness areas) and by the State of Florida (USFS 1999;
F.S. section 590.01).
In addition, both petitions contend that the scrub-jay recovery
plan needs to be revised and implemented because it is out-of-date.
State Regulatory Process
The 2003 petition contends that Florida law does not protect scrub-
jays from habitat destruction, which is the major cause of the species'
decline in Florida (F.A.C. 68A-27.004(1)(a); 52 FR 20717). In addition,
the 2003 petition claims that in 1999, the Florida Fish and Wildlife
Conservation Commission (FWC) adopted a new process for classifying
species as endangered, threatened, or species of special concern (IUCN
1994); therefore, it is questionable whether the scrub-jay still
classifies as a threatened species under the Florida statute. The
International Union for Conservation of Nature and Natural Resources
(IUCN) classifies the scrub-jay as ``vulnerable'' (IUCN 2002), which
would be the equivalent of a ``species of special concern'' for the
purposes of the FWC classification, meaning that the scrub-jay would
receive less protection if the status is subsequently adopted by FWC.
Such a designation would allow catastrophic losses to the scrub-jay
population before it could be classified as threatened by the FWC.
Evaluation of Information in the Petitions
Service Regulatory Process
Under the section 7 consultation process, Federal agencies are
required to consult with us when their actions may affect a listed
species. Therefore, impacts to unoccupied habitat may not be considered
unless the unoccupied habitat has been designated as critical habitat
for the species under consultation. The petitions, therefore, present a
factual statement about the Act. The 2002 petition cites a letter from
the Service, in which we acknowledge that there are many areas with
potentially suitable scrub habitat that have become overgrown due to
fire suppression. Most of these sites are unoccupied by scrub-jays due
to the unsuitable condition of the site's habitat, and therefore, the
consultation requirement is not triggered. The 2003 petition cites
court cases that do not relate specifically to the scrub-jay. The
petitions do not provide substantial information showing a clear link
between the section 7 process and their assertion that the species
should be reclassified. We do, however, address the petitions' claims
regarding threats of habitat destruction and fragmentation under Factor
A. We also note that designation of unoccupied areas as critical
habitat would not impose any requirement that land owners or land
managers not suppress fires or conduct prescribed burns on that land.
The Service and the USACE have permitted numerous developments in
central Brevard County and other portions of the species' range, as
claimed by the petitioners. These permits are processed in accordance
with applicable laws, regulations, and agency policies. The 2002
petition cited a project for Plantation Point (Service 2002b; Fritschie
2002, Attachment B) as evidence that development in central Brevard
County that may affect scrub-jays continues to occur. The court
determined that the biological opinion for this project followed the
provisions of the Act (U.S. District Court 2002). Further, the claim
raised by the 2002 petition is not different from that addressed in the
1987 final rule listing the species, because section 7 of the Act has
not been radically changed since that time. As for the evidence cited
by the 2003 petition (Service 2003), that 28 incidental take permits
had been issued by the Service for projects involving scrub-jay habitat
between 1994 and 2002 and that additional applications have been
received and processed to date, this information is factual. However,
cumulative impacts of these actions are addressed as part of compliance
with the National Environmental Policy Act (42 U.S.C. 4371 et seq.) and
in the individual intra-Service section 7 consultations conducted on
the actions. The petitions do not provide substantial information
showing a link between these regulatory actions and their assertion
that the scrub-jay should be reclassified to endangered. We do,
however, address the petitions' claims regarding threats of habitat
destruction and fragmentation under Factor A.
The Service has a rangewide approach to scrub-jay mitigation for
development activity, which has been revised most recently in 2004
(Service 2004). The 2003 petition claims that we fail to follow our own
mitigation guidance for impacts to scrub-jays, as shown in the outcome
of the Plantation Point project (Service 1999, 2002b). The mitigation
guidelines referenced (Service 1999) are written for incidental take
permit actions under section 10(a)(1)(B) of the Act, which requires
that impacts be avoided, minimized, and mitigated to the maximum extent
practicable. The project used as an example to demonstrate our failure
to follow the guidelines, however, was not processed under the
provisions of section 10, but rather section 7. Under section 7, the
action agency is required only to minimize impacts; the measures
outlined in the mitigation guidance are utilized for section 7 subject
to the ``ultimate determination of acceptability by the action agency''
(Service 2002b, 2004). The petitioners have not presented substantial
information that indicates that as a result of this mitigation
guidance, the scrub-jay is now in danger of extinction throughout all
or a significant portion of its range.
All counties in which scrub-jays are present, as well as many of
the local municipalities, have been advised of their responsibilities
under the Act. Even though Brevard County did not
[[Page 4097]]
adopt a regional HCP, numerous individual permit applications have been
reviewed by the Service. The petition does not provide substantial
information to support their claim that take is occurring as a result
of local governments that are not requiring Federal permits. Further,
the petition does not identify a clear link between the claim and the
need to reclassify the species to endangered status.
The 2003 petition cites the Ocala National Forest as an example of
the inadequacies of regulatory programs, citing a 31 percent drop in
the number of scrub-jays from the early 1980s to the early 2000s. (Cox
1987; USFS 2002). We contend, however, that the survey methodologies
cited in these two studies were different from one another and cannot
be compared to demonstrate a drop in scrub-jay numbers. Further, no
substantial information was presented by the petitioner that population
declines on Federal lands in Florida are placing the scrub-jay in
danger of extinction throughout all or a significant portion of its
range.
Finally, both the 2002 and 2003 petitions contend that the scrub-
jay recovery plan is in need of revision. Recovery plans are not
regulatory documents; therefore, this claim is not relevant to this
factor. Further, the petitions do not provide substantial information
that as a result of the lack of revision to the scrub-jay recovery
plan, the scrub-jay is now in danger of extinction throughout all or a
significant portion of its range. We note, however, that the recovery
plan is being revised.
State Regulatory Process
The 2003 petition's contention that Florida law does not protect
scrub-jays from habitat destruction is not different from that
addressed in the 1987 final rule. In addition, while the information
that a new process has been adopted by FWC for classifying species as
endangered, threatened, or species of special concern is factual,
according to the most recent list of imperiled species for the State of
Florida (FWC 2004), the scrub-jay is still listed as threatened. The
petition provides no substantial information that indicates as a result
of the existing State laws, the scrub-jay is now in danger of
extinction throughout all or a significant portion of its range.
E. Other Natural or Manmade Factors Affecting the Species Continued
Existence
Information Provided in the Petitions
Both the 2002 and 2003 petitions claim that the fire regime in
scrub habitat has been altered, which has negatively affected scrub-
jays (TNC 2001). Scrub-jay habitat, if not continuously managed, can
quickly become population sinks for scrub-jays, creating difficulties
for land managers and negatively impacting scrub-jays (Breininger and
Carter 2003; Breininger and Oddy 2004). Throughout the northern portion
of the species' range, the petitioners attribute population declines of
scrub-jays to scrub fragmentation and degradation, due primarily to
widespread fire suppression (Cox et al. 1994). In addition, the 2003
petition claims that a previous model for the scrub-jay (Root 1998) may
have been too optimistic, because the possibility that certain kinds of
impacts of environmental noise (such as loud sounds) on scrub-jays was
ignored (Heino and Sabadell 2003).
Evaluation of Information in the Petitions
We share opinions provided in both the 2002 and 2003 petitions
regarding the negative effects to scrub-jays from fire suppression
(Breininger and Carter 2003; Breininger and Oddy 2004). However, fire
suppression was considered a threat to the scrub-jay when the species
was first listed as threatened in 1987 (52 FR 20715). The petitions
provided no substantial information that indicates as a result of fire
suppression, the scrub-jay is now in danger of extinction throughout
all or a significant portion of its range.
The work presented by Heino and Sabadell (2003) indicates that
ignoring the effects of environmental noise on scrub-jays in population
viability analysis can result in serious biases to a model. However,
the petitioner did not provide substantial information that by not
considering environmental noise, the scrub-jay is now in danger of
extinction throughout all or a significant portion of its range.
Finding
We have reviewed the petitions and literature cited in the
petitions, and we have evaluated that information in relation to other
pertinent literature. After this review and evaluation, we find the
petitions do not present substantial scientific information to indicate
that reclassification of the Florida scrub-jay from threatened to
endangered may be warranted at this time. Although we will not be
commencing a status review in response to these petitions, we will
continue to monitor the species' population status and trends,
potential threats, and ongoing management actions that might be
important with regard to the conservation of the scrub-jay across its
range.
We encourage interested parties to continue to gather data that
will assist with the conservation of the species. If you wish to
provide information regarding scrub-jays, you may submit your
information or materials to the Field Supervisor, Jacksonville Fish and
Wildlife Office (see ADDRESSES section).
