Federal Register / Vol. 74, No. 241 / Thursday, December 17, 2009 / Proposed Rules

effective date of the final rule was the
focus of VSC’s petition.
In its petition, VSC asserted that the
effect of the language relating to the
effective date of the new regulation, as
originally published on April 30, 2008,
would ‘‘force manufacturers to start
their MY 2010 no later than with April
30, 2009 production.’’ VSC indicated
that manufacturers need flexibility to
decide when to change over from MY
2009 production to MY 2010
production. VSC suggested detailed
changes to the regulatory language
originally published.
The agency believes that the May 16,
2008 correction notice adequately
addressed the issues raised by VSC. The
corrections make clear that model year
2010 and 2011 vehicles manufactured
on or after October 27, 2008 must
comply with the new rule. The agency
believes the October 27, 2008 effective
date provided sufficient lead time for
manufacturers to plan for the
manufacture of model year 2010
vehicles. It is the agency’s intent that all
model year 2010 vehicles comply with
the new VIN rule.
The May 16, 2008 corrections also
make clear that ‘‘all motor vehicles
identified as model year 2009 or earlier
vehicles by their manufacturer’’ must
comply with the current 49 CFR Part
565, which is included in the final rule
as Subpart C.
Because the May 16, 2008 correction
notice addresses VSC’s concerns, the
agency is denying this petition for
reconsideration.
B. Time Period Identifiers for Other
Types of Vehicles
The April 30, 2008 final rule included
a change in the 17 character VIN system
for passenger cars, multipurpose
passenger vehicles, and trucks with
GVWRs of 10,000 lb (4,536 kg) or less,
that effectively indicates whether the
vehicle is from the first 30 year or
second 30 year period of the VIN
system’s life. In its petition for
reconsideration, the Highway Loss Data
Institute (HLDI), an affiliate of the
Insurance Institute for Highway Safety
(IIHS), asked that changes be made to
the VIN final rule so that the 30 year
period in which motorcycles and
pickup trucks greater than 10,000 lb
GVWR were manufactured can be
identified.
While not submitted as a petition for
reconsideration, NHTSA also received a
comment from Penton Media expressing
a concern similar to HLDI’s but relating
to all vehicles other than passenger cars,
multipurpose passenger vehicles, and
trucks with a GVWR of 4536 kg (10,000
lb) or less, including trucks with a
VerDate Nov<24>2008
15:00 Dec 16, 2009
Jkt 220001
GVWR greater than 4536 kg (10,000 lb),
buses, motorcycles, trailers, and low
speed-vehicles.
For motorcycles, HLDI suggested two
options for allowing one to determine
the 30 year period in which a
motorcycle was manufactured. The first
would require motorcycles to use
prescribed alphabetic characters in
position 9 of the VIN as check digits, as
opposed to the numeric characters now
required for all vehicles including
motorcycles. The second option would
allow motorcycles to use an alphabetic
character not now permitted to be used
in VINs, specifically I, O, or Q, in VIN
positions 4–8 to indicate that the
motorcycle is a model year in the range
2010–39.
With regard to pickups, HLDI cited
four different makes/series that include
versions with GVWRs both above and
below 10,000 lb. HLDI asked that
manufacturers of ‘‘any make/series with
GVWRs both above and below the
10,000 pound threshold follow the new
rules for all vehicles of that make/
series—that is, to use alphabetic
characters in VIN position 7 to indicate
model years 2010–2039 and ensure the
uniqueness of VINs for this group of
vehicles.’’ HLDI said its analysis of the
VINs of the four makes/series of pickups
it cited indicated that alphabetic
characters have not been used in
position 7 of the VINs of these vehicles.
While HLDI and Penton Media have
identified a difference in the way
vehicles under 10,000 lb GVWR and
motorcycles and vehicles over 10,000 lb
GVWR are treated in the final rule, the
agency does not believe that it has a
sufficient basis to change Part 565 per
the petitioner’s request. The issues
raised were not raised in the rulemaking
and are therefore outside the scope of
the rulemaking and cannot be addressed
in response to a petition for
reconsideration. As such, we are
denying HLDI’s petition for
reconsideration.
Our decision-making on the issues
raised by HLDI would benefit from
public comments on the issues. The
agency believes that the changes
suggested by HLDI could have a
substantial impact on data systems that
utilize VINs. Furthermore, it seems
likely that some users of data systems
may not derive any benefit from the
changes they would be forced to make.
The changes to the VIN system HLDI
proposes would likely benefit HLDI’s
research activities, but we are uncertain
as to what adverse effects making these
changes might have on others with data
systems that rely on the VIN. Any
changes of the sort suggested by HLDI
would benefit from notice and comment
PO 00000
Frm 00014
Fmt 4702
Sfmt 4702
66937
rulemaking to assure, among other
things, that these changes would not
have an adverse impact on
manufacturers of the vehicles involved
as well as on the many data systems that
utilize the VIN, such as those
maintained by State motor vehicle
departments, insurance companies, and
others. NHTSA believes that any
proposed change to longstanding
operating principles of the VIN system,
such as allowing the use of the
characters I, O, and Q, must be carefully
and thoroughly reviewed to make sure
that a solution in one context does not
create problems in another. Again,
public comments on the change would
be beneficial.
With respect to HLDI’s concern that
certain makes and models of pickup
trucks have vehicle versions that are
above 10,000 lb GVWR and below
10,000 lb and might therefore use two
different approaches to assigning VINs
to these vehicles, NHTSA believes that
for the vehicles mentioned by HLDI, the
problem, at least for now, does not exist.
NHTSA contacted the manufacturers of
the pickups cited by HLDI. Each
indicated that in the case of the pickup
makes and models cited by HLDI, the
manufacturer applies the VIN character
scheme required of vehicles less than
10,000 lb GVWR to all versions of the
vehicles.
Therefore, for the aforementioned
reasons, we decline to make the changes
suggested by HLDI. We note that we are
continuing efforts to review the VIN
system, so the suggested changes could
be pursued if further revisions to the
VIN system are proposed at a later time.

SUMMARY: We, the U.S. Fish and
Wildlife Service (Service), announce a
12–month finding on a petition to
expand the listing of the Canada lynx
(Lynx canadensis) to include the State
of New Mexico, under the Endangered
Species Act of 1973, as amended (Act).
After a review of the best available
scientific and commercial information,
we find that the petition to change the
boundary of the listing of Canada lynx
is warranted but precluded by higher
priority actions to amend the Lists of
Endangered and Threatened Wildlife
and Plants. We have determined that
Canada lynx are regularly and
frequently crossing the State boundary
between Colorado and New Mexico.
When lynx cross the boundary, their
status under the Act changes, leaving
lynx in New Mexico without Federal
protection. Upon publication of this 12–
month petition finding, we will add
lynx in New Mexico to our candidate
species list with a listing priority
number of 12. We will develop a
proposed rule to amend the listing of
lynx in the lower 48 States as our
priorities allow (see section of
Preclusion and Expeditious Progress).
DATES: This finding was made on
December 17, 2009.
ADDRESSES: This finding is available on
the Internet at https://
www.regulations.gov at Docket Number
[FWS-R6-ES-2008-0122]. Supporting
documentation we used to prepare this
finding is available for public
inspection, by appointment, during
normal business hours at the U.S. Fish
and Wildlife Service, Montana Field
Office, 585 Shepard Way, Helena, MT
59601; telephone (406) 449-5225. Please
submit any new information, materials,
comments, or questions concerning this
finding to the above street address.

SUPPLEMENTARY INFORMATION:
Background
Section 4(b)(3)(B) of the Act (16
U.S.C. 1531 et seq.) requires that, for
any petition containing substantial
scientific or commercial information
indicating that listing the species may
be warranted, we make a finding within
12 months of the date of receipt of the
petition. In this finding, we determine
whether the petitioned action is: (a) Not
VerDate Nov<24>2008
15:00 Dec 16, 2009
Jkt 220001
warranted, (b) warranted, or (c)
warranted, but that immediate proposal
of a regulation implementing the
petitioned action is precluded by other
pending proposals to determine whether
species are threatened or endangered,
and expeditious progress is being made
to add or remove qualified species from
the Federal Lists of Endangered and
Threatened Wildlife and Plants. Section
4(b)(3)(C) of the Act requires that we
treat a petition for which the requested
action is found to be warranted but
precluded as though resubmitted on the
date of such finding, that is, requiring a
subsequent finding to be made within
12 months. We must publish these 12–
month findings in the Federal Register.
Previous Federal Action
In the final listing rule for the Canada
lynx, dated March 24, 2000, the Service
defined a contiguous DPS of the Canada
lynx based on the international
boundary with Canada and State
boundaries (65 FR 16052). The final rule
included all States in the historic and
current range of lynx, along with areas
that lynx dispersed to frequently but
had no history of reproduction or
population maintenance. New Mexico
was not included in the listed area due
to a lack of any historic record of lynx
in the State and lack of sufficient lynx
habitat and prey. The 2000 listing of
lynx contained a discussion of lynx
dispersal behavior and our prediction
that lynx would continue to disperse
outside of currently occupied habitat
and the current listed area. We
determined that these attempted
dispersal events would not constitute an
expansion of lynx range or
recolonization of previously occupied
habitat. Subsequent to publication of the
final rule in 2000, lynx dispersed out of
the Southern Rockies reintroduction
area with relatively high frequency
(Shenk 2007, p. 16) to other States
including New Mexico.
In 2003, we published a clarification
of the 2000 listing rule in which we
determined that lynx were not
endangered throughout a significant
portion of their range (68 FR 40076). We
also determined that lynx in the
contiguous United States exist either as
resident populations or as dispersers,
and that due to their proclivity for
moving long distances, lynx are often
found repeatedly in habitats that cannot
sustain breeding populations. This
repeated dispersal into habitats that
ultimately cannot support the species
(‘‘sink’’ habitats) often leads to
confusion among scientists and the
public about where lynx populations
may be viable. At the time of the
clarification, we considered sink
PO 00000
Frm 00015

Sfmt 4702
habitats (those with lynx habitat
characteristics but without the requisite
habitat scale or prey densities to support
reproducing populations of lynx) to be
within the range of lynx, as a
conservative approach to conservation.
We believed that in sink habitats, there
existed the possibility that lynx could
establish small local or ephemeral
populations, and contribute to the
persistence of the DPS, although there
was admittedly no evidence that this
was the case.
In 2007, we published a Clarification
of Findings for the 2000 listing rule in
which we determined that the
significant portion of the range of lynx
in the contiguous States is the northern
Rocky Mountains and the North
Cascades (72 FR 1186); however, the
listed entity (the 14-State DPS) did not
change. This clarification also
determined that much of the range of
lynx consists of marginal habitat that
cannot and never could support resident
lynx populations, and so is not
biologically significant to the
conservation of the DPS.
On August 8, 2007, we received a
petition from Forest Guardians, Sinapu,
Center for Native Ecosystems, Animal
Protection Institute, Animal Protection
of New Mexico, Carson Forest Watch,
and Sierra Club, Rio Grande Chapter,
requesting that we amend the final
listing rule for the lynx DPS to include
New Mexico as part of the range of the
listed entity. Included in the petition
was supporting information regarding
our interpretation of the Act, our DPS
policy, and inconsistency with the
preamble to the March 2000 listing rule,
as well as scientific information the
petitioners deemed important to the
petitioned action. We acknowledged the
receipt of the petition in a letter to
Matthew K. Bishop, Western
Environmental Law Center, dated
August 24, 2007. In that letter we also
stated that due to staff and budget
limitations we anticipated beginning
work on the finding in Fiscal Year (FY)
2009 and that we would process a
finding on the petition as soon as funds
became available. An evaluation of
emergency listing was conducted. Based
on the population status and alleged
threats described in the petition, we
found no evidence to support
emergency listing in New Mexico at that
time.
On April 17, 2008, we received a
complaint for failure to complete a 90–
day petition finding. A settlement
agreement was finalized, in which we
agreed to submit a 90–day finding by
December 15, 2008. On December 18,
2008, we published a 90–day finding in
which we determined that the
E:\FR\FM\17DEP1.SGM
17DEP1
Federal Register / Vol. 74, No. 241 / Thursday, December 17, 2009 / Proposed Rules
petitioners presented substantial
information indicating that changing the
listing rule to include New Mexico may
be warranted (73 FR 76990). This notice
constitutes the 12–month finding on the
August 8, 2007, petition to amend the
final listing rule for the lynx DPS to
include New Mexico.
We published a final rule designating
critical habitat for lynx in the Federal
Register on November 9, 2006 (71 FR
66007). On July 20, 2007, we announced
that we would review the November 9,
2006, final critical habitat rule after
questions were raised about the integrity
of scientific information used and
whether the decision made was
consistent with the appropriate legal
standards. Based on our review of the
previous final critical habitat
designation, we determined that the
critical habitat designation may not
comport with the best available
scientific and commercial information.
On January 15, 2008, the U.S. District
Court for the District of Columbia issued
an order stating the Service’s deadlines
for a proposed rule for revised critical
habitat by February 15, 2008, and a final
rule for revised critical habitat by
February 15, 2009. Consequently, our
proposed rule was signed on February
13, 2008, and submitted to the Federal
Register. The proposed rule was
subsequently published in the Federal
Register on February 28, 2008 (73 FR
10860), and a final rule was published
in the Federal Register on February 25,
2009 (74 FR 8616).

Species Information
Biology
The biology of the species is
comprehensively covered in the
Previous Federal Actions, including the
final rule listing the species (65 FR
16052), the two clarifications of that
final rule (68 FR 40076; 72 FR 1186) and
the 2009 final critical habitat rule (74 FR
8616).
Here, we provide a short summary of
the relevant species biology. Canada
lynx are medium-sized cats, generally
measuring 30 to 35 inches (75 to 90
centimeters) long and weighing 18 to 23
pounds (8 to 10.5 kilograms) (Quinn and
Parker 1987, Table 1). They have large,
well-furred feet and long legs for
traversing snow; tufts on the ears; and
short, black-tipped tails. Lynx are
specialized predators of snowshoe hare
(Lepus americanus) (McCord and
Cardoza 1982, p. 744; Quinn and Parker
1987, pp. 684-685; Aubry et al. 2000,
pp. 375-378). Lynx are dependent on
snowshoe hare populations for survival,
so lynx habitat suitability is strongly
correlated with snowshoe hare habitat
VerDate Nov<24>2008
15:00 Dec 16, 2009
Jkt 220001
quality. We consider adequate
snowshoe hare densities to be the most
important habitat component for lynx.
Lynx and snowshoe hares are strongly
associated with what is broadly
described as boreal forest (Bittner and
Rongstad 1982, p. 154; McCord and
Cardoza 1982, p. 743; Quinn and Parker
1987, p. 684; Agee 2000, p. 39; Aubry
et al. 2000, pp. 378-382; Hodges 2000a,
pp. 136-140 and 2000b, pp. 183-191;
McKelvey et al. 2000a, pp. 211-232).
The predominant vegetation of boreal
forest is conifer trees, primarily species
of spruce (Picea spp.) and fir (Abies
spp.) (Elliot-Fisk 1988, pp. 34-35, 3742). In the contiguous United States, the
boreal forest types transition to
deciduous temperate forest in the
Northeast and Great Lakes and to
subalpine forest in the west (Agee 2000,
pp. 40-41). Lynx habitat can generally
be described as moist boreal forests that
have cold, snowy winters and a highdensity snowshoe hare prey base (Quinn
and Parker 1987, pp. 684-685; Agee
2000, pp. 39-47; Aubry et al. 2000, pp.
373-375; Buskirk et al. 2000a, pp. 397405; Ruggiero et al. 2000, pp. 445-447).
In mountainous areas, the boreal
forests that lynx use are characterized
by scattered moist forest types with high
hare densities in a matrix of other
habitats (e.g., hardwoods, dry forest,
non-forest) with low hare densities. In
these areas, lynx incorporate the matrix
habitat (non-boreal forest habitat
elements) into their home ranges and
use it for traveling between patches of
boreal forest that support high hare
densities where most foraging occurs. In
areas like the northern and southern
Rockies where high-density hare habitat
is fragmented by other habitat types,
hare density must remain high at the
landscape scale (i.e., averaged over all
habitat types) for lynx to maintain
residency and reproduction.
Snow conditions also determine the
distribution of lynx (Ruggiero et al.
2000, pp. 445-449). Lynx are
morphologically and physiologically
adapted for hunting in deep snow and
surviving in areas that have cold winters
with deep, fluffy snow for extended
periods. These adaptations provide lynx
a competitive advantage over potential
competitors, such as bobcats (Lynx
rufus) or coyotes (Canis latrans)
(McCord and Cardoza 1982, p. 748;
Buskirk et al. 2000b, pp. 86-95;
Ruediger et al. 2000, pp. 1-11; Ruggiero
et al. 2000, pp. 445, 450). Bobcats and
coyotes have a higher foot load (more
weight per surface area of foot), which
causes them to sink into the snow more
than lynx. Therefore, bobcats and
coyotes cannot efficiently hunt in fluffy
or deep snow and are at a competitive
PO 00000
Frm 00016
Fmt 4702
Sfmt 4702
66939
disadvantage to lynx. Long-term snow
conditions presumably limit the winter
distribution of potential lynx
competitors such as bobcats (McCord
and Cardoza 1982, p. 748) or coyotes.
Lynx Habitat Requirements
Because of the patchy and temporal
nature of high-quality snowshoe hare
habitat, lynx populations require large
boreal forest landscapes to ensure that
sufficient high- quality snowshoe hare
habitat is available and to ensure that
lynx may move freely among patches of
suitable habitat and among
subpopulations of lynx. Populations
that are composed of a number of
discrete subpopulations, connected by
dispersal, are called metapopulations
(McKelvey et al. 2000b, p. 25).
Individual lynx maintain large home
ranges (reported as generally ranging
between 12 to 83 square miles (mi2) (31
to 216 square kilometers (km2)) (Koehler
1990, p. 847; Aubry et al. 2000, pp. 382386; Squires and Laurion 2000, pp. 342347; Squires et al. 2004, pp. 13-16,
Table 6; Vashon et al. 2005, pp. 7-11;
Shenk 2009a, pp. 6-7). The size of lynx
home ranges varies depending on
abundance of prey, the animal’s gender
and age, the season, and the density of
lynx populations (Koehler 1990, p. 849;
Poole 1994, pp. 612-616; Slough and
Mowat 1996, pp. 951, 956; Aubry et al.
2000, pp. 382-386; Mowat et al. 2000,
pp. 276-280; Vashon et al. 2005, pp. 910). When densities of snowshoe hares
decline, for example, lynx enlarge their
home ranges to obtain sufficient
amounts of food to survive and
reproduce, or seek new habitats in
which to establish a home range through
dispersal.
In the contiguous United States, the
boreal forest landscape is naturally
patchy and transitional because it is the
southern edge of the distributional range
of boreal forest. This patchiness
generally limits snowshoe hare
populations in the contiguous United
States from achieving densities similar
to those of the expansive northern
boreal forest in Canada (Wolff 1980, pp.
123-128; Buehler and Keith 1982, pp.
24, 28; Koehler 1990, p. 849; Koehler
and Aubry 1994, p. 84). Additionally,
the presence of more snowshoe hare
predators and competitors at southern
latitudes may inhibit the potential for
high-density hare populations (Wolff
1980, p. 128). As a result, lynx generally
occur at relatively low densities in the
contiguous United States compared to
the high lynx densities that occur in the
northern boreal forest of Canada (Aubry
et al. 2000, pp. 375, 393-394) or to the
densities of species such as the bobcat,
which is a habitat and prey generalist.

Federal Register / Vol. 74, No. 241 / Thursday, December 17, 2009 / Proposed Rules
Lynx are highly mobile and often
move long distances (greater than 60
miles (mi) (100 kilometers (km))) during
dispersal attempts (Aubry et al. 2000,
pp. 386-387; Mowat et al. 2000, pp. 290294). Lynx disperse primarily when
snowshoe hare populations decline
(Ward and Krebs 1985, pp. 2821-2823;
O’Donoghue et al. 1997, pp. 156, 159;
Poole 1997, pp. 499-503). Sub-adult
lynx disperse even when prey is
abundant (Poole 1997, pp. 502-503)
because local home ranges with
abundant hares are generally occupied
by established adult lynx and sub-adults
must look elsewhere to establish new
home ranges. Lynx also make
exploratory movements outside their
home ranges (Aubry et al. 2000, p. 386;
Squires et al. 2001, pp. 18-26).
The boreal forest landscape is
naturally dynamic. Forest stands within
the landscape change as they undergo
succession after natural or humancaused disturbances such as fire, insect
epidemics, wind, ice, disease, and forest
management (Elliot-Fisk 1988, pp. 4748; Agee 2000, pp. 47-69). As a result,
lynx habitat within the boreal forest
landscape is typically patchy because
the boreal forest contains stands of
differing ages and conditions, some of
which are suitable as lynx foraging or
denning habitat (or will become suitable
in the future due to forest succession)
and some of which serve as travel routes
for lynx moving between foraging and
denning habitat (McKelvey et al. 2000c,
pp. 427-434; Hoving et al. 2004, pp.
290-292).
Snowshoe hares comprise a majority
of the lynx diet (Nellis et al. 1972, pp.
323-325; Brand et al. 1976, pp. 422-425;
Koehler 1990, p. 848; Apps 2000, pp.
358-359, 363; Aubry et al. 2000, pp.
375-378; Mowat et al. 2000, pp. 267268; von Kienast 2003, pp. 37-38;
Squires et al. 2004, p. 15, Table 8).
When snowshoe hare populations are
low, female lynx produce few or no
kittens that survive to independence
(Nellis et al. 1972, pp. 326-328; Brand
et al. 1976, pp. 420, 427; Brand and
Keith 1979, pp. 837-838, 847; Poole
1994, pp. 612-616; Slough and Mowat
1996, pp. 953-958; O’Donoghue et al.
1997, pp. 158-159; Aubry et al. 2000,
pp. 388-389; Mowat et al. 2000, pp. 285287). Lynx prey opportunistically on
other small mammals and birds,
particularly during lows in snowshoe
hare populations, but alternate prey
species may not sufficiently compensate
for low availability of snowshoe hares,
resulting in reduced reproductive
success and reduced lynx populations
(Brand et al. 1976, pp. 422-425; Brand
and Keith 1979, pp. 833-834; Koehler

Jkt 220001
1990, pp. 848-849; Mowat et al. 2000,
pp. 267-268).
In northern Canada, lynx populations
fluctuate in response to the cycling of
snowshoe hare populations (Hodges
2000a, pp. 118-123; Mowat et al. 2000,
pp. 270-272). Although snowshoe hare
populations in the northern portion of
their range show strong, regular
population cycles, these fluctuations are
generally much less pronounced in the
southern portion of their range in the
contiguous United States (Hodges
2000b, pp. 165-173). In the contiguous
United States, the degree to which
regional local lynx population
fluctuations are influenced by local
snowshoe hare population dynamics is
unclear. However, researchers
anticipated that, because of natural
fluctuations in snowshoe hare
populations, there will be periods when
lynx densities are extremely low.
Because lynx population dynamics,
survival, and reproduction are closely
tied to snowshoe hare availability, lynx
habitat suitability is directly tied to hare
habitat quality. Lynx generally
concentrate their foraging and hunting
activities in habitat patches where
snowshoe hare populations are high
(Koehler et al. 1979, p. 442; Ward and
Krebs 1985, pp. 2821-2823; Murray et
al. 1994, p. 1450; O’Donoghue et al.
1997, pp. 155, 159-160 and 1998, pp.
178-181). Snowshoe hares are most
abundant in forest stands with dense
understories that provide forage, cover
to escape from predators, and protection
during extreme weather (Wolfe et al.
1982, pp. 665-669; Litvaitis et al. 1985,
pp. 869-872; Hodges 2000a, pp. 136-140
and 2000b, pp. 183-195). Generally, hare
densities are higher in regenerating,
earlier successional forest stages
because they have greater understory
structure than mature forests (Buehler
and Keith 1982, p. 24; Wolfe et al. 1982,
pp. 665-669; Koehler 1990, pp. 847-848;
Hodges 2000b, pp. 183-195; Homyack
2003, pp. 63, 141; Griffin 2004, pp. 8488). However, snowshoe hares can be
abundant in mature forests with dense
understories (multi-storied stands)
especially in the Rocky Mountains
(Griffin 2004, pp. 53-54, Squires et al.
2006, p. 15).
Within the boreal forest, lynx den
sites are located where coarse woody
debris, such as downed logs and
windfalls, provides security and thermal
cover for lynx kittens (McCord and
Cardoza 1982, pp. 743-744; Koehler
1990, pp. 847-849; Slough 1999, p. 607;
Squires and Laurion 2000, pp. 346-347;
Squires et al. 2008, p. 1503; Organ
2001). The amount of structure (e.g.,
downed, large, woody debris) appears to
be more important than the age of the

forest stand for lynx denning habitat
(Mowat et al. 2000, pp. 10-11); however,
proximity to forest stands with high
horizontal cover (and presumably high
snowshoe hare density) does contribute
to overall suitability of denning sites
(Squires et al. 2008, p. 1503).
The 14-State Canada Lynx DPS
The Service listed lynx in 2000 within
what we determined to be the
contiguous United States DPS, which
included the known current and
historical range of the lynx (68 FR
40080). In specifying where lynx was
listed, we used State boundaries to
circumscribe the outer limits in which
the DPS was found at the time, using the
best science available. This range
included portions of the States of
Colorado, Idaho, Maine, Minnesota,
Montana, Washington, and Wyoming,
and also areas that could support
dispersers – portions of the above States
along with portions of Michigan, New
Hampshire, New York, Oregon, Utah,
Vermont, and Wisconsin (68 FR 40099).
We did not consider other areas outside
of boreal forest, where dispersing lynx
had only been sporadically documented
in the past, to be within the range of the
lynx, because we deemed these areas to
be currently incapable of supporting
dispersing lynx. These areas included
Connecticut, Indiana, Iowa,
Massachusetts, Nebraska, Nevada, North
Dakota, Ohio, Pennsylvania, South
Dakota, and Virginia (68 FR 40099).
We did not include New Mexico in
this list of States because no lynx
occurred there, and we had no
information to indicate that lynx had
ever been documented there, even
sporadically. Therefore, we determined
that the boundaries delineating the
range of lynx did not include New
Mexico because it was not within the
current or historical range of the species
(68 FR 40083). In addition, no review of
potential habitat in New Mexico was
conducted. We did not consider lynx
recently released into Colorado that
strayed into New Mexico as sufficient
reason to include New Mexico within
the range of lynx because there was no
evidence that habitat in New Mexico
historically supported lynx, or that lynx
moving into New Mexico would support
maintenance of the lynx DPS (68 FR
40083).
In 1998, when the Service proposed to
list the lynx in the United States, no
wild (or reintroduced) lynx were known
to exist in Colorado, which represented
the extreme southern edge of the
species’ range (65 FR 16059). Boreal
forest habitat in Colorado and
southeastern Wyoming, the Southern
Rocky Mountain Region, is isolated
E:\FR\FM\17DEP1.SGM

from boreal forest in Utah and
northwestern Wyoming by intervening
grassland and shrubland habitats, and is
naturally highly fragmented (65 FR
16059).
It was uncertain whether lynx records
from Colorado represented a small selfsustaining lynx population, or whether
historical records represented dispersers
that arrived during high population
cycles of lynx and subsequently died
out. Under the scenario whereby lynx in
Colorado were not a self-sustaining
population, some of the dispersers may
have remained for a period of years if
hare populations were high enough to
support residents and reproduction, but
eventually succumbed to a lack of
consistent, high-quality habitat and food
sources. We believe that this is the most
likely historical scenario in the southern
Rockies based on the small number of
historic lynx records (McKelvey et al.
2000a, pp. 229-231), low snowshoe hare
densities (Andersen et al. 1980, Table 5;
Dolbeer and Clark 1975, p. 539; Hodges
2000b, Table 7.5; Malaney 2003, pp. 65,
87, 90; Zahratka and Shenk 2008, Table
4), and overall low reproductive output
of the reintroduced population (Shenk
2007, pp. 11-13).
In 1999, the Colorado Division of
Wildlife (CDOW) reintroduced 22 wild
lynx from Canada and Alaska into
southwestern Colorado (Shenk 2007, p.
20). By 2003, when we clarified the
listing rule (68 FR 40076, July 3, 2003),
no data indicated that the lynx released
could be supported by the habitat
available in Colorado. In their 2007
Wildlife Research Report, CDOW
continued to conclude that ‘‘what is yet
to be determined is whether current
conditions in Colorado can support the
recruitment necessary to offset annual
mortality in order to sustain the
population’’ (Shenk 2007, p. 18).
Colorado was included in the 14-State
DPS in 2000, because records indicated
that lynx were documented there
historically; however, it was not known
whether the habitat occurred in the
requisite quantity and quality to sustain
lynx populations. Therefore, the 2000
listing represented a conservative
approach, which included areas in the
range of the species when evidence of
long-term persistence was lacking, but
enough evidence existed that it could
not be discounted.
In 2000, when the final listing rule
was published, we were not aware of
any information to indicate that lynx
existed in New Mexico, that it was ever
occupied historically, or that it could
sustain lynx. As a consequence, we did
not include New Mexico in the listing
rule or special rule concerning lynx in
the contiguous 14-State DPS. We now
VerDate Nov<24>2008
15:00 Dec 16, 2009
Jkt 220001
have documentation that lynx
reintroduced in Colorado have
attempted to disperse in many
directions, primarily into New Mexico,
Utah, and Wyoming, but also into eight
other States (Shenk 2007, pp. 6, 9). No
reproduction has been documented in
New Mexico or Utah, but one den was
found in Wyoming (Shenk 2007, p. 15),
and one den was found within 5.6 mi
(9 km) of the Colorado-New Mexico
State boundary (Shenk 2009b, entire).
We also point out that lynx dispersal
away from the reintroduction area in
southern Colorado is what would be
predicted if lynx were reintroduced into
an area that consisted mostly of
unsuitable habitat, and dispersing
animals were searching for habitats with
the requisite prey densities that could
support resident animals. Our review of
the evidence indicates that this habitat
is most likely found north of the
southern Rockies.
We included an analysis in the final
lynx listing rule (68 FR 40081) on
whether lynx were both discrete and
significant in each of the four regions of
the contiguous United States where it
exists (the Northeast, Great Lakes,
Southern Rocky Mountains, and
Northern Rocky Mountains/Cascades).
We determined that none of the regions
individually constitute significantly
unique or unusual ecological settings
and, therefore, did not individually
meet the DPS criteria. Therefore, the
lynx was listed as a single contiguous
United States DPS defined by 14 States.
Lynx in the Southern Rockies
Lynx reintroduction into the southern
Rocky Mountains in southern Colorado
occurred between 1999 and 2006 with a
total of 218 animals released (Shenk
2008, p. 1). Reintroduced lynx were
captured from the wild in Alaska and
Canada. Also in 1999, the CDOW began
a post-release monitoring program that
tracked reintroduced animals (and,
opportunistically, their wild-born
progeny). The purpose of the monitoring
program was to determine whether the
reintroduced population was
reproducing and to collect habitat use
and other ecological data. Prior to
beginning reintroductions, CDOW
reviewed the historic evidence of lynx
occupation and concluded that the
Southern Rockies in Colorado represent
the extreme southern edge of the range
of lynx. At that time, lynx were either
extirpated or at such low densities that
the extant population was no longer
viable (Seidel et al. 1998, p. 4).
Throughout the post-release monitoring
program, CDOW has maintained that the
reintroduction is experimental in nature
and that it remains to be determined
PO 00000
Frm 00018
Fmt 4702
Sfmt 4702
66941
whether the southern Rockies can
support enough lynx reproduction to
offset mortality (Shenk 2007, p. 18)
At the time of the lynx listing in 2000,
the CDOW reintroduction program was
in its beginning stages and without postrelease data or analysis to evaluate its
effectiveness. Consequently, when lynx
were listed, lynx released into Colorado,
prior to and after the listing, received
the full protection of the Act as a
threatened species. At that time, it was
our determination that habitat in
Colorado represented the southernmost
extension of lynx range (65 FR 16052, p.
16059), based on the lack of historic
lynx records in New Mexico. Therefore,
when the line demarcating the range of
lynx (and consequently the regulatory
reach of the final listing rule) was
placed at the border of Colorado and
New Mexico, it was thought that this
boundary placement conservatively
encompassed all of the lynx range in the
southern Rocky Mountains, and that
while lynx may occasionally wander
south of that line, such occurrences
would be rare (68 FR 40076, p. 40077).
Habitat in New Mexico that may
support all or a portion of lynx lifehistory needs is limited to the San Juan
and Sangre de Cristo mountains in the
northern part of the State. Both of these
ranges are contiguous with mountains
in Colorado where reintroduced lynx
are residing and have reproduced. Both
of these mountain ranges have
snowshoe hares (Malaney and Frey
2006, p. 879); however, densities at the
landscape scale (i.e., the scale of a lynx
home range) are low (0.13 hares/ha (0.32
hares/ac) before seasonal recruitment)
and are likely not high enough to
support resident lynx (Malaney 2003,
pp. 65, 87, 90).
Most of the habitat in question is
managed by the Carson and Santa Fe
National Forests of the U.S. Forest
Service (USFS). Approximately 596,000
ac (241,193 ha) of spruce-fir forest types
lie within this area, 440,000 ac of which
are on National Forest system lands
(USFS 2009, pp. 5-6). On the Carson and
Santa Fe National Forests,
approximately 536,400 ac (217,073 ha)
have characteristics of potential lynx
habitat (spruce fir and other cold, wet
conifer forest types), about 45 percent of
which occurs in designated wilderness
(USFS 2009, p. 7). As a reference, in the
reintroduced Colorado lynx population
the average lynx home range size is
108,109 ac (43,750 ha) (calculated from
data in Shenk 2007, p. 11). Other small
patches of isolated spruce-fir and mixed
conifer habitats occur in northern New
Mexico, but due to their small size, they
are not considered to have any value as
lynx habitats (USFS 2009, p. 7). In their
E:\FR\FM\17DEP1.SGM
17DEP1
wwoods2 on DSK1DXX6B1PROD with PROPOSALS_PART 1
66942
Federal Register / Vol. 74, No. 241 / Thursday, December 17, 2009 / Proposed Rules
information submitted for this finding,
the USFS concluded that due to the lack
of historic record, lack of reproduction
in reintroduced lynx, low prey
densities, high densities of competitor
species and relatively low snow levels
for this area, New Mexico is likely to
function as a ‘‘sink’’ habitat for the
reintroduced lynx population in the
southern Rockies meaning that mortality
would exceed recruitment in this area
(USFS 2009, p. 17).
As explained in our 2007 clarification
of the 2000 listing rule (72 FR 1186, p.
1189), the presence of snowshoe hares
at high population densities is a prerequisite for lynx residency in any area.
However, neither the presence of
snowshoe hare populations nor
contiguity with a lynx population are
sufficient to assure that lynx will reside
in an area that lacks a high density of
snowshoe hares at a scale large enough
to support a lynx home range (landscape
scale). Snowshoe hare habitat is of
varying quality, and in the lower-48
States only the highest quality habitat
(i.e., that with the highest snowshoe
hare densities) is capable of supporting
lynx populations and contributing to the
maintenance of the DPS. Since longterm studies of snowshoe hare densities
across the range of the DPS have not
occurred, we believe that historic and
recent data about where lynx have or do
reside and reproduce, provide the best
available scientific data concerning
which areas have the requisite high hare
densities and amount of habitat required
to support lynx.
The best source of lynx presence data
for the historic period is McKelvey et al.
(2000b entire). McKelvey et al. (2000b,
entire) focus on the use of ‘‘verifiable
records’’ as the most appropriate
locality records for lynx. Verifiable
records are those for which there is
verifiable evidence that the animal in
question was a lynx, such as a museum
specimen, a diagnostic photograph, or
an expert that had the animal ‘‘in hand’’
at the time of identification. We believe
that the need for accurate identification
of lynx necessitates that only verifiable
records be used, and we refer readers to
McKelvey et al. (2008, entire) for a
discussion of evidentiary standards.
Others have attempted to determine the
historic range of lynx through the use of
other types of evidence. Frey (2006,
entire) used a combination of habitat
associations, biogeography, and habitat
contiguity with known populations to
infer lynx historic range to areas
without historic records.
While this method may point to areas
that were potentially in the range of the
species, it presumes that we understand
the species’ life-history needs and the
VerDate Nov<24>2008

Jkt 220001
habitat condition well enough to know
if the habitat in question would support
the species. In the case of lynx, we
know that lynx are dependent on highdensity snowshoe hare populations, in
the sense that we know of no lynx
population that occurs in an area
without a high density of hares.
Conversely, we do know of habitats
with low-density hare populations that
have no lynx populations, such as the
Olympic Peninsula in Washington,
southwestern Montana/central Idaho,
and much of Appalachia (Hall 1981, p.
317). We do not know what the
threshold landscape-scale hare density
is that will allow lynx to persist, or
precisely what habitat characteristics
allow persistence of reproducing
populations.
Many depictions of lynx geographic
range simply draw lines around
peripheral occurrence records without
reference to habitat (e.g., Hall 1981).
These depictions are likely to overestimate the extent of lynx range due to
the animal’s tendency to move long
distances across unsuitable habitats
while attempting to disperse. Attempted
dispersal forays also bring lynx into
human-dominated landscapes where
they are disproportionately likely to
experience mortality in a way that leads
to discovery by humans and thus these
animals are disproportionately likely to
become locality records. We believe that
the best available scientific information
to inform determinations about historic
range is verifiable occurrence records
due to their high level of reliability.
Verifiable species records, put in the
context of suitable habitat distribution,
are crucial to determining what the
historic distribution of a species was,
especially when there is some doubt
about the habitat characteristics that are
sufficient to support the species. By
using verifiable occurrence records, we
essentially give lynx a vote in the
process, where scientific uncertainty
does not permit us to determine
precisely where suitable habitat exists.
For these reasons, we believe that lynx
geographic range is best depicted
through a combination of reliable
occurrence records and suitable habitat.
Because lynx have a tendency to move
long distances during unsuccessful
dispersal attempts, the actual range of
the species is much smaller than what
is depicted on range maps that simply
draw lines around peripheral
occurrence records and do not consider
habitat type and quality. For examples
of analyses that use both occurrence
records and suitable habitat to
determine where a species may have
occurred in the past, see McKelvey et al.

(2000b, entire) and Aubry et al. (2007,

In our 2007 clarification of the 2000
listing rule, we further determined that
the northern Rockies and North
Cascades formed a significant portion of
the DPS’ range because this geographic
area and its constituents (e.g., habitat)
was the primary region necessary to
support the long-term existence of the
contiguous U.S. DPS (72 FR 1186, p.
1189). This finding was based on the
remaining portions of the DPS range
being composed of marginal habitat
where lynx presence was tied more
directly to immigration of lynx from
Canada. In that document we
emphasized that, just because habitat is
marginal, it does not mean that lynx can
no longer live there. Instead, marginal
habitat means that such areas cannot
and may never have supported resident
lynx populations (72 FR 1186, p. 1188).
Data collected by CDOW during their
post-release monitoring also are
valuable in determining where lynx may
find snowshoe hare densities that may
(at least occasionally) support
reproduction. Between September 1999
and March 2007, 60 individual lynx (37
females, 23 males) crossed into New
Mexico (Shenk 2007, p. 10). Many of
these lynx passed back into Colorado
after short forays into New Mexico, 14
mortalities occurred, and some lynx
may have resided in New Mexico yearround, although that has not been
documented (Shenk 2007, pp. 10-26).
From September 1999 through March
2007, CDOW found no evidence that
any of the 37 female lynx that have
moved into New Mexico reproduced or
attempted to reproduce (Shenk 2007, p.
15). However, CDOW does not monitor
lynx that leave the State of Colorado as
intensively as it does in Colorado. Based
on the large number of female lynx that
have moved into New Mexico over the
period of the reintroduction program
without evidence of any reproduction,
we cannot conclude that New Mexico
lynx habitat is of high enough quality to
support a resident population. Indeed,
we share CDOW’s concern that the
southern Rockies in their entirety may
not be able to sustain a lynx population.
Lynx suffer proportionally higher
mortality in New Mexico than in other
States (Shenk 2001, p. 14). However,
statistical tests to determine whether
this difference was significantly
different than what might be expected
by chance were not reported. In
addition, lynx mortality due to
deliberate killing (shooting) was higher
as a proportion of all mortalities in
Colorado (53.8 percent) (where all lynx
are protected by the Act) than they were
outside Colorado (46.2 percent) (where
E:\FR\FM\17DEP1.SGM
17DEP1
Federal Register / Vol. 74, No. 241 / Thursday, December 17, 2009 / Proposed Rules
occur due to the lack of protections
under the Act.
We are assigning a listing priority
number (LPN) of 12 to amending the
listing of lynx to include New Mexico
in the listed DPS. We assign an LPN of
1 to 12 (higher number being of lower
priority), depending on the magnitude
of threats (high vs. moderate to low),
immediacy of threats (imminent or
nonimminent), and taxonomic status of
the species (in order of priority:
monotypic genus (a species that is the
sole member of a genus); species; or part
of a species (subspecies, DPS, or
significant portion of the range)). We are
assigning an LPN of 12 based on
nonimminent threats of a low
magnitude to the lynx DPS occurring
from human-caused mortality to lynx
dispersing to New Mexico and the lack
of protection under the Act for these
lynx. Human-caused mortality is a
factor affecting lynx in New Mexico;
however, this impact does not occur at
a level such that it creates a significant
threat to lynx in the contiguous United
States and to the DPS as a whole. The
magnitude of threats to the lynx DPS,
inclusive of those lynx in New Mexico,
is low. The threats occur infrequently
and are nonimminent. Furthermore, as
described above, the amount of suitable
habitat for lynx in New Mexico is
considered negligible relative to the
amount of habitat within the listed
range. Potential impacts to the habitat
have not been documented to threaten
lynx, either in New Mexico or outside
of it. The majority of lynx and its
habitats within the DPS are already
protected by the Act. Because lynx in
the lower 48 States are listed as a DPS,
the appropriate LPN for this level of
magnitude and immediacy of threats is
a 12.
Finding
wwoods2 on DSK1DXX6B1PROD with PROPOSALS_PART 1
lynx have Act protections in some
States but not New Mexico and others)
(Shenk 2007, Table 9). Therefore, the
evidence presented by Shenk does not
indicate that lack of the Act’s
protections in New Mexico is a
significant contributor to lynx mortality.
Rather, lynx mortality is high for lynx
that disperse outside of high-quality
lynx habitat whether they remain under
the protection of the Act or not. This
result is to be expected, because
dispersal outside of quality habitat is
usually only done under stress, such as
inability to find food or displacement by
another lynx. Dispersal outside of lynx
habitat is likely to place lynx in humandominated landscapes such as
agricultural areas, settlements, and
transportation corridors, where lynx
mortalities are more likely to occur.
It is our determination, based on the
historic lack of evidence of lynx
occurrence in New Mexico (McKelvey et
al. 2000a, Table 8.1) and the recent
evidence of lynx dispersal attempts into
northern New Mexico (Shenk 2007, pp.
29-31), that lynx in New Mexico
represent attempted dispersers, rather
than lynx establishing residency in
suitable habitat as defined in our
clarification of findings (68 FR 40076, p.
40077). We also believe that the habitat
in New Mexico is a population ‘‘sink’’,
in that it is unlikely to support lynx
reproduction to the extent that
recruitment will ever be able to offset
population mortality, even absent any
human-caused mortality. However, as
we stated in 2003, at the time of listing
we considered lynx found in population
sinks such as New Mexico to be
dispersers but we included these areas
within the range of lynx (68 FR 40076,
p. 40080).
Emergency Listing
We may list a species effective
immediately under Section 4 of the Act
if there is any emergency posing a
significant risk to the well-being of the
species. Because threats identified to
lynx in New Mexico are determined to
be nonimminent and of low magnitude
for the species in the lower 48 States
(DPS) as a whole, the Secretary has
determined not to exercise his
discretion to invoke the provisions to
immediately put the protections of the
Act in place for the Canada lynx in New
Mexico.
We have carefully assessed the
information in the petition along with
the best scientific and commercial data
available. This 12–month finding
reflects and incorporates information
that we received during the public
comment period or that we obtained
through consultation, literature
research, and field visits.
On the basis of this review, we have
determined that revising the boundaries
of the DPS as identified in the 2000 final
listing rule for Canada lynx to include
New Mexico is warranted. This finding
is based on the fact that the information
that we used to describe the southern
boundary of the DPS at the time of
listing is out of date. Lynx that attempt
to disperse outside of areas that support
populations should be protected from
direct or indirect mortality that may

Importance of Habitat in New Mexico
for the Lynx DPS
The information gathered in the
process of preparing this finding does
not indicate that New Mexico can
support reproducing lynx. We still find
PO 00000
Frm 00020
Fmt 4702
Sfmt 4702

no evidence that New Mexico can
support a lynx population or that
habitat in New Mexico may play a
supporting role in conservation of the
DPS. We believe that the only role that
habitat in New Mexico may play in lynx
conservation is to allow individuals to
survive long enough to move north back
into more suitable habitat. Managing to
increase habitat suitability for lynx in
New Mexico would be counterproductive to this end, because it is
unlikely that habitat in New Mexico can
be made to support lynx, and the
important goal is that lynx return to the
population further north. Therefore, we
do not recommend that habitat in New
Mexico be managed to support
residency and reproduction, as are
habitats further north in Colorado and
the northern Rockies. For example, we
do not think it would be appropriate for
the USFS to implement management
based on the Lynx Conservation
Assessment and Strategy such as that
found in the Southern Rocky Mountain
Lynx Amendment (USFS 2008).
Significant Portion of the Range
Under the Act and our implementing
regulations, a species may warrant
listing if it is threatened or endangered
in a significant portion of its range.
Because this 12–month finding to
amend the listing of the Canada lynx
DPS is warranted but precluded, we do
not need to perform a ‘‘significant
portion of the range’’ analysis for the
species at this time.
Preclusion and Expeditious Progress
Preclusion is a function of the listing
priority of a species in relation to the
resources that are available and
competing demands for those resources.
Thus, in any given FY, multiple factors
dictate whether it will be possible to
undertake work on a proposed listing
regulation or whether promulgation of
such a proposal is warranted but
precluded by higher-priority listing
actions.
The resources available for listing
actions are determined through the
annual Congressional appropriations
process. The appropriation for the
Listing Program is available to support
work involving the following listing
actions: Proposed and final listing rules;
90–day and 12–month findings on
petitions to add species to the Lists of
Endangered and Threatened Wildlife
and Plants (Lists) or to change the status
of a species from threatened to
endangered; annual determinations on
prior ‘‘warranted but precluded’’
petition findings as required under
section 4(b)(3)(C)(i) of the Act; critical
habitat petition findings; proposed and

Federal Register / Vol. 74, No. 241 / Thursday, December 17, 2009 / Proposed Rules
final rules designating critical habitat;
and litigation-related, administrative,
and program-management functions
(including preparing and allocating
budgets, responding to Congressional
and public inquiries, and conducting
public outreach regarding listing and
critical habitat). The work involved in
preparing various listing documents can
be extensive and may include, but is not
limited to: gathering and assessing the
best scientific and commercial data
available and conducting analyses used
as the basis for our decisions; writing
and publishing documents; and
obtaining, reviewing, and evaluating
public and peer review comments on
proposed rules and incorporating
relevant information into final rules.
The number of listing actions that we
can undertake in a given year also is
influenced by the complexity of those
listing actions; that is, more complex
actions generally are more costly. For
example, during the past several years,
the cost (excluding publication costs)
for preparing a 12–month finding,
without a proposed rule, has ranged
from approximately $11,000 for one
species with a restricted range and
involving a relatively uncomplicated
analysis, to $305,000 for another species
that is wide-ranging and involved a
complex analysis.
We cannot spend more than is
appropriated for the Listing Program
without violating the Anti-Deficiency
Act (see 31 U.S.C. § 1341(a)(1)(A)). In
addition, in FY 1998 and for each FY
since then, Congress has placed a
statutory cap on funds that may be
expended for the Listing Program, equal
to the amount expressly appropriated
for that purpose in that FY. This cap
was designed to prevent funds
appropriated for other functions under
the Act (for example, recovery funds for
removing species from the Lists), or for
other Service programs, from being used
for Listing Program actions (see House
Report 105-163, 105th Congress, 1st
Session, July 1, 1997).
Recognizing that designation of
critical habitat for species already listed
would consume most of the overall
Listing Program appropriation, Congress
also put a critical habitat subcap in
place in FY 2002, and has retained it
each subsequent year to ensure that
some funds are available for other work
in the Listing Program: ‘‘The critical
habitat designation subcap will ensure
that some funding is available to
address other listing activities’’ (House
Report No. 107-103, 107th Congress, 1st
Session, June 19, 2001). In FY 2002 and
each year until FY 2006, the Service has
had to use virtually the entire critical
habitat subcap to address court-
VerDate Nov<24>2008
15:00 Dec 16, 2009
Jkt 220001
mandated designations of critical
habitat. Consequently, none of the
critical habitat subcap funds have been
available for other listing activities. In
FY 2007, we were able to use some of
the critical habitat subcap funds to fund
proposed listing determinations for
high-priority candidate species. In FY
2008 and 2009, while we were unable
to use any of the critical habitat subcap
funds to fund proposed listing
determinations, we did use some of this
money to fund the critical habitat
portion of some proposed listing
determinations, so that the proposed
listing determination and proposed
critical habitat designation could be
combined into one rule, thereby being
more efficient in our work. In FY 2010,
we anticipate being able to do the same.
Thus, through the listing cap, the
critical habitat subcap, and the amount
of funds needed to address courtmandated critical habitat designations,
Congress and the courts have in effect
determined the amount of money
available for other listing activities.
Therefore, the funds in the listing cap,
other than those needed to address
court-mandated critical habitat for
already-listed species, set the limits on
our determinations of preclusion and
expeditious progress.
Congress also recognized that the
availability of resources was the key
element in deciding, when making a 12–
month petition finding, whether we
would prepare and issue a listing
proposal or instead make a ‘‘warranted
but precluded’’ finding for a given
species. The Conference Report
accompanying Public Law 97-304,
which established the current statutory
deadlines for listing and the warrantedbut-precluded finding requirements that
are currently contained in the Act, states
(in a discussion on 90–day petition
findings that by its own terms also
covers 12–month findings) that the
deadlines were ‘‘not intended to allow
the Secretary to delay commencing the
rulemaking process for any reason other
than that the existence of pending or
imminent proposals to list species
subject to a greater degree of threat
would make allocation of resources to
such a petition [i.e., for a lower-ranking
species] unwise.’’
In FY 2010, expeditious progress is
that amount of work that can be
achieved with $10,471,000, which is the
amount of money that Congress
appropriated for the Listing Program
(that is, the portion of the Listing
Program funding not related to critical
habitat designations for species that are
already listed). Our process is to make
our determinations of preclusion on a
nationwide basis to ensure that the

Frm 00021
Fmt 4702
Sfmt 4702
species most in need of listing will be
addressed first and also because we
allocate our listing budget on a
nationwide basis. The $10,471,000 will
be used to fund work in the following
categories: compliance with court orders
and court-approved settlement
agreements requiring that petition
findings or listing determinations be
completed by a specific date; section 4
(of the Act) listing actions with absolute
statutory deadlines; essential litigationrelated, administrative, and listing
program-management functions; and
high-priority listing actions for some of
our candidate species. The allocations
for each specific listing action are
identified in the Service’s FY 2009
Allocation Table (part of our
administrative record). For FY 2010,
Congress recently passed an
appropriations bill. We are working on
finalizing our allocation of money for
specific listing actions.
In FY 2007, we had more than 120
species with an LPN of 2, based on our
September 21, 1983, guidance for
assigning an LPN for each candidate
species (48 FR 43098). Using this
guidance, we assign each candidate an
LPN of 1 to 12, depending on the
magnitude of threats (high vs. moderate
to low), immediacy of threats (imminent
or nonimminent), and taxonomic status
of the species (in order of priority:
monotypic genus (a species that is the
sole member of a genus); species; or part
of a species (subspecies, DPS, or
significant portion of the range)). The
lower the listing priority number, the
higher the listing priority (that is, a
species with an LPN of 1 would have
the highest listing priority). Because of
the large number of high-priority
species, we further ranked the candidate
species with an LPN of 2 by using the
following extinction-risk type criteria:
International Union for the
Conservation of Nature and Natural
Resources (IUCN) Red list status/rank,
Heritage rank (provided by
NatureServe), Heritage threat rank
(provided by NatureServe), and species
currently with fewer than 50
individuals, or 4 or fewer populations.
Those species with the highest IUCN
rank (critically endangered), the highest
Heritage rank (G1), the highest Heritage
threat rank (substantial, imminent
threats), and currently with fewer than
50 individuals, or fewer than 4
populations, comprised a group of
approximately 40 candidate species
(‘‘Top 40’’). These 40 candidate species
have had the highest priority to receive
funding to work on a proposed listing
determination. As we work on proposed
and final listing rules for these 40
E:\FR\FM\17DEP1.SGM
17DEP1
Federal Register / Vol. 74, No. 241 / Thursday, December 17, 2009 / Proposed Rules
candidates, we are applying the ranking
criteria to the next group of candidates
with LPNs of 2 and 3 to determine the
next set of highest priority candidate
species. In FY 2008-2009, we funded
work on proposed listing
determinations for 61 candidate species,
most of which have an LPN of 2,
although these have not been published
to date. There are currently 56 candidate
species with an LPN of 2 that nave not
received funding for preparation of
proposed listing rules.
To be more efficient in our listing
process, as we work on proposed rules
for these species in the next several
years, we are preparing multi-species
proposals when appropriate, and these
may include species with lower priority
if they overlap geographically or have
the same threats as a species with an
LPN of 2. In addition, available staff
resources also are a factor in
determining high-priority species
provided with funding. Finally,
proposed rules for reclassification of
threatened species to endangered are
lower priority, since as listed species,
they are already afforded the protection
of the Act and implementing
regulations.
Our decision that a proposed rule to
revise the boundaries of the Canada
lynx DPS under the Act is warranted but
precluded is based on the low
magnitude and non-imminence of
threats to the Canada lynx in the lower
48-contiguous States (i.e., the DPS). As
we have already determined that the
potential threats are of low magnitude
and are not imminent, we conclude that
this action should receive the lowest
listing priority. We consider the priority
for amending the Canada lynx DPS to be
lower than for other candidate species
in need of protection under the Act. As
described in the ‘‘Finding’’ section
above, we have assigned an LPN of 12
to this amendment. In accordance with
guidance we published on September
21, 1983, we assign an LPN to each
candidate species (48 FR 43098). Such
a priority ranking guidance system is
required under section 4(h)(3) of the Act
(16 U.S.C. 1533(h)(3)). Using this
guidance, we assign each candidate an
LPN of 1 to 12, depending on the
magnitude of threats, imminence of
threats, and taxonomic status; the lower
the listing priority number, the higher
the listing priority, i.e., a species with
an LPN of 1 would have the highest
listing priority. We currently have 56
species with an LPN of 2 that have not
received funding yet (see Table 1 of the
November 9, 2009, Notice of Review; 74
FR 57866). For the next 2 years, we have
funded proposed listings for several
66945
species with an LPN of 2. We consider
amending the Canada lynx DPS to be
precluded by these high-priority
candidate species.
As explained above, a determination
that listing is warranted but precluded
also must demonstrate that expeditious
progress is being made to add or remove
qualified species to and from the Lists
of Endangered and Threatened Wildlife
and Plants. (Although we do not discuss
it in detail here, we also are making
expeditious progress in removing
species from the list under the Recovery
Program, which is funded by a separate
line item in the budget of the
Endangered Species Program. As
explained above in our description of
the statutory cap on Listing Program
funds, the Recovery Program funds and
actions supported by them cannot be
considered in determining expeditious
progress made in the Listing Program.)
As with our ‘‘precluded’’ finding,
expeditious progress in adding qualified
species to the Lists is a function of the
resources available and the competing
demands for those funds. Given that
limitation, we find that we made
progress in FY 2009 in the Listing
Program and will continue to make
progress in FY 2010. This progress
included preparing and publishing the
following determinations:

Our expeditious progress also
included work on listing actions that we
funded in FY 2009 but have not yet
completed to date. These actions are
listed below. Actions in the top section
of the table are being conducted under
a deadline set by a court. Actions in the
middle section of the table are being
conducted to meet statutory timelines,
that is, timelines required under the
Act. Actions in the bottom section of the
table are high-priority listing actions.
These actions include work primarily
on species with an LPN of 2, and
selection of these species is partially
based on available staff resources, and
when appropriate, include species with
a lower priority if they overlap
geographically or have the same threats
as the species with the high priority.
Including these species together in the
same proposed rule results in
considerable savings in time and
funding, as compared to preparing
separate proposed rules for each of them
in the future.

Funds for listing actions for these species were provided in previous FYs.
We funded a proposed rule for this subspecies with an LPN of 3 ahead of other species with LPN of 2, because the threats to the species
were so imminent and of a high magnitude that we considered emergency listing if we were unable to fund work on a proposed listing rule in FY
2008.
3 Funds for these high-priority listing actions were provided in FY 2008 and FY 2009.

We have endeavored to make our
listing actions as efficient and timely as
possible, given the requirements of the
relevant laws and regulations, and
constraints relating to workload and
personnel. We are continually
considering ways to streamline
processes or achieve economies of scale,
such as by batching related actions
together. Given our limited budget for
implementing section 4 of the Act, the
actions described above collectively
constitute expeditious progress.
We will revise the boundaries of the
Canada lynx DPS in the contiguous
United States when funding is available
for discretionary listing actions. At such
time that funding becomes available to
develop a proposed rule, we will
develop revised boundaries for the
listed DPS based on the biology of the

species. We will continue to monitor the
status of this DPS as new information
becomes available. This review will
determine if a change in status is
warranted, including the need to make
prompt use of emergency listing
procedures.
We intend any amendment to this
listing to be as accurate as possible.
Therefore, we will continue to accept
additional information and comments
on the status of and threats to this DPS
from all concerned governmental
agencies, the scientific community,

Endangered and Threatened Wildlife and Plants; 12-month Finding
on a Petition To Change the Final Listing of the Distinct Population
Segment of the Canada Lynx To Include New Mexico
AGENCY: Fish and Wildlife Service, Interior.
[[Page 66938]]
ACTION: Notice of 12-month petition finding.
-----------------------------------------------------------------------
SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a
12-month finding on a petition to expand the listing of the Canada lynx
(Lynx canadensis) to include the State of New Mexico, under the
Endangered Species Act of 1973, as amended (Act). After a review of the
best available scientific and commercial information, we find that the
petition to change the boundary of the listing of Canada lynx is
warranted but precluded by higher priority actions to amend the Lists
of Endangered and Threatened Wildlife and Plants. We have determined
that Canada lynx are regularly and frequently crossing the State
boundary between Colorado and New Mexico. When lynx cross the boundary,
their status under the Act changes, leaving lynx in New Mexico without
Federal protection. Upon publication of this 12-month petition finding,
we will add lynx in New Mexico to our candidate species list with a
listing priority number of 12. We will develop a proposed rule to amend
the listing of lynx in the lower 48 States as our priorities allow (see
section of Preclusion and Expeditious Progress).
DATES: This finding was made on December 17, 2009.
ADDRESSES: This finding is available on the Internet at https://www.regulations.gov at Docket Number [FWS-R6-ES-2008-0122]. Supporting
documentation we used to prepare this finding is available for public
inspection, by appointment, during normal business hours at the U.S.

SUPPLEMENTARY INFORMATION:
Background
Section 4(b)(3)(B) of the Act (16 U.S.C. 1531 et seq.) requires
that, for any petition containing substantial scientific or commercial
information indicating that listing the species may be warranted, we
make a finding within 12 months of the date of receipt of the petition.
In this finding, we determine whether the petitioned action is: (a) Not
warranted, (b) warranted, or (c) warranted, but that immediate proposal
of a regulation implementing the petitioned action is precluded by
other pending proposals to determine whether species are threatened or
endangered, and expeditious progress is being made to add or remove
qualified species from the Federal Lists of Endangered and Threatened
Wildlife and Plants. Section 4(b)(3)(C) of the Act requires that we
treat a petition for which the requested action is found to be
warranted but precluded as though resubmitted on the date of such
finding, that is, requiring a subsequent finding to be made within 12
months. We must publish these 12-month findings in the Federal
Register.
Previous Federal Action
In the final listing rule for the Canada lynx, dated March 24,
2000, the Service defined a contiguous DPS of the Canada lynx based on
the international boundary with Canada and State boundaries (65 FR
16052). The final rule included all States in the historic and current
range of lynx, along with areas that lynx dispersed to frequently but
had no history of reproduction or population maintenance. New Mexico
was not included in the listed area due to a lack of any historic
record of lynx in the State and lack of sufficient lynx habitat and
prey. The 2000 listing of lynx contained a discussion of lynx dispersal
behavior and our prediction that lynx would continue to disperse
outside of currently occupied habitat and the current listed area. We
determined that these attempted dispersal events would not constitute
an expansion of lynx range or recolonization of previously occupied
habitat. Subsequent to publication of the final rule in 2000, lynx
dispersed out of the Southern Rockies reintroduction area with
relatively high frequency (Shenk 2007, p. 16) to other States including
New Mexico.
In 2003, we published a clarification of the 2000 listing rule in
which we determined that lynx were not endangered throughout a
significant portion of their range (68 FR 40076). We also determined
that lynx in the contiguous United States exist either as resident
populations or as dispersers, and that due to their proclivity for
moving long distances, lynx are often found repeatedly in habitats that
cannot sustain breeding populations. This repeated dispersal into
habitats that ultimately cannot support the species (``sink'' habitats)
often leads to confusion among scientists and the public about where
lynx populations may be viable. At the time of the clarification, we
considered sink habitats (those with lynx habitat characteristics but
without the requisite habitat scale or prey densities to support
reproducing populations of lynx) to be within the range of lynx, as a
conservative approach to conservation. We believed that in sink
habitats, there existed the possibility that lynx could establish small
local or ephemeral populations, and contribute to the persistence of
the DPS, although there was admittedly no evidence that this was the
case.
In 2007, we published a Clarification of Findings for the 2000
listing rule in which we determined that the significant portion of the
range of lynx in the contiguous States is the northern Rocky Mountains
and the North Cascades (72 FR 1186); however, the listed entity (the
14-State DPS) did not change. This clarification also determined that
much of the range of lynx consists of marginal habitat that cannot and
never could support resident lynx populations, and so is not
biologically significant to the conservation of the DPS.
On August 8, 2007, we received a petition from Forest Guardians,
Sinapu, Center for Native Ecosystems, Animal Protection Institute,
Animal Protection of New Mexico, Carson Forest Watch, and Sierra Club,
Rio Grande Chapter, requesting that we amend the final listing rule for
the lynx DPS to include New Mexico as part of the range of the listed
entity. Included in the petition was supporting information regarding
our interpretation of the Act, our DPS policy, and inconsistency with
the preamble to the March 2000 listing rule, as well as scientific
information the petitioners deemed important to the petitioned action.
We acknowledged the receipt of the petition in a letter to Matthew K.
Bishop, Western Environmental Law Center, dated August 24, 2007. In
that letter we also stated that due to staff and budget limitations we
anticipated beginning work on the finding in Fiscal Year (FY) 2009 and
that we would process a finding on the petition as soon as funds became
available. An evaluation of emergency listing was conducted. Based on
the population status and alleged threats described in the petition, we
found no evidence to support emergency listing in New Mexico at that
time.
On April 17, 2008, we received a complaint for failure to complete
a 90-day petition finding. A settlement agreement was finalized, in
which we agreed to submit a 90-day finding by December 15, 2008. On
December 18, 2008, we published a 90-day finding in which we determined
that the
[[Page 66939]]
petitioners presented substantial information indicating that changing
the listing rule to include New Mexico may be warranted (73 FR 76990).
This notice constitutes the 12-month finding on the August 8, 2007,
petition to amend the final listing rule for the lynx DPS to include
New Mexico.
We published a final rule designating critical habitat for lynx in
the Federal Register on November 9, 2006 (71 FR 66007). On July 20,
2007, we announced that we would review the November 9, 2006, final
critical habitat rule after questions were raised about the integrity
of scientific information used and whether the decision made was
consistent with the appropriate legal standards. Based on our review of
the previous final critical habitat designation, we determined that the
critical habitat designation may not comport with the best available
scientific and commercial information. On January 15, 2008, the U.S.
District Court for the District of Columbia issued an order stating the
Service's deadlines for a proposed rule for revised critical habitat by
February 15, 2008, and a final rule for revised critical habitat by
February 15, 2009. Consequently, our proposed rule was signed on
February 13, 2008, and submitted to the Federal Register. The proposed
rule was subsequently published in the Federal Register on February 28,
2008 (73 FR 10860), and a final rule was published in the Federal
Register on February 25, 2009 (74 FR 8616).
Species Information
Biology
The biology of the species is comprehensively covered in the
Previous Federal Actions, including the final rule listing the species
(65 FR 16052), the two clarifications of that final rule (68 FR 40076;
72 FR 1186) and the 2009 final critical habitat rule (74 FR 8616).
Here, we provide a short summary of the relevant species biology.
Canada lynx are medium-sized cats, generally measuring 30 to 35 inches
(75 to 90 centimeters) long and weighing 18 to 23 pounds (8 to 10.5
kilograms) (Quinn and Parker 1987, Table 1). They have large, well-
furred feet and long legs for traversing snow; tufts on the ears; and
short, black-tipped tails. Lynx are specialized predators of snowshoe
hare (Lepus americanus) (McCord and Cardoza 1982, p. 744; Quinn and
Parker 1987, pp. 684-685; Aubry et al. 2000, pp. 375-378). Lynx are
dependent on snowshoe hare populations for survival, so lynx habitat
suitability is strongly correlated with snowshoe hare habitat quality.
We consider adequate snowshoe hare densities to be the most important
habitat component for lynx.
Lynx and snowshoe hares are strongly associated with what is
broadly described as boreal forest (Bittner and Rongstad 1982, p. 154;
McCord and Cardoza 1982, p. 743; Quinn and Parker 1987, p. 684; Agee
2000, p. 39; Aubry et al. 2000, pp. 378-382; Hodges 2000a, pp. 136-140
and 2000b, pp. 183-191; McKelvey et al. 2000a, pp. 211-232). The
predominant vegetation of boreal forest is conifer trees, primarily
species of spruce (Picea spp.) and fir (Abies spp.) (Elliot-Fisk 1988,
pp. 34-35, 37-42). In the contiguous United States, the boreal forest
types transition to deciduous temperate forest in the Northeast and
Great Lakes and to subalpine forest in the west (Agee 2000, pp. 40-41).
Lynx habitat can generally be described as moist boreal forests that
have cold, snowy winters and a high-density snowshoe hare prey base
(Quinn and Parker 1987, pp. 684-685; Agee 2000, pp. 39-47; Aubry et al.
2000, pp. 373-375; Buskirk et al. 2000a, pp. 397-405; Ruggiero et al.
2000, pp. 445-447).
In mountainous areas, the boreal forests that lynx use are
characterized by scattered moist forest types with high hare densities
in a matrix of other habitats (e.g., hardwoods, dry forest, non-forest)
with low hare densities. In these areas, lynx incorporate the matrix
habitat (non-boreal forest habitat elements) into their home ranges and
use it for traveling between patches of boreal forest that support high
hare densities where most foraging occurs. In areas like the northern
and southern Rockies where high-density hare habitat is fragmented by
other habitat types, hare density must remain high at the landscape
scale (i.e., averaged over all habitat types) for lynx to maintain
residency and reproduction.
Snow conditions also determine the distribution of lynx (Ruggiero
et al. 2000, pp. 445-449). Lynx are morphologically and physiologically
adapted for hunting in deep snow and surviving in areas that have cold
winters with deep, fluffy snow for extended periods. These adaptations
provide lynx a competitive advantage over potential competitors, such
as bobcats (Lynx rufus) or coyotes (Canis latrans) (McCord and Cardoza
1982, p. 748; Buskirk et al. 2000b, pp. 86-95; Ruediger et al. 2000,
pp. 1-11; Ruggiero et al. 2000, pp. 445, 450). Bobcats and coyotes have
a higher foot load (more weight per surface area of foot), which causes
them to sink into the snow more than lynx. Therefore, bobcats and
coyotes cannot efficiently hunt in fluffy or deep snow and are at a
competitive disadvantage to lynx. Long-term snow conditions presumably
limit the winter distribution of potential lynx competitors such as
bobcats (McCord and Cardoza 1982, p. 748) or coyotes.
Lynx Habitat Requirements
Because of the patchy and temporal nature of high-quality snowshoe
hare habitat, lynx populations require large boreal forest landscapes
to ensure that sufficient high- quality snowshoe hare habitat is
available and to ensure that lynx may move freely among patches of
suitable habitat and among subpopulations of lynx. Populations that are
composed of a number of discrete subpopulations, connected by
dispersal, are called metapopulations (McKelvey et al. 2000b, p. 25).
Individual lynx maintain large home ranges (reported as generally
ranging between 12 to 83 square miles (mi\2\) (31 to 216 square
kilometers (km\2\)) (Koehler 1990, p. 847; Aubry et al. 2000, pp. 382-
386; Squires and Laurion 2000, pp. 342-347; Squires et al. 2004, pp.
13-16, Table 6; Vashon et al. 2005, pp. 7-11; Shenk 2009a, pp. 6-7).
The size of lynx home ranges varies depending on abundance of prey, the
animal's gender and age, the season, and the density of lynx
populations (Koehler 1990, p. 849; Poole 1994, pp. 612-616; Slough and
Mowat 1996, pp. 951, 956; Aubry et al. 2000, pp. 382-386; Mowat et al.
2000, pp. 276-280; Vashon et al. 2005, pp. 9-10). When densities of
snowshoe hares decline, for example, lynx enlarge their home ranges to
obtain sufficient amounts of food to survive and reproduce, or seek new
habitats in which to establish a home range through dispersal.
In the contiguous United States, the boreal forest landscape is
naturally patchy and transitional because it is the southern edge of
the distributional range of boreal forest. This patchiness generally
limits snowshoe hare populations in the contiguous United States from
achieving densities similar to those of the expansive northern boreal
forest in Canada (Wolff 1980, pp. 123-128; Buehler and Keith 1982, pp.
24, 28; Koehler 1990, p. 849; Koehler and Aubry 1994, p. 84).
Additionally, the presence of more snowshoe hare predators and
competitors at southern latitudes may inhibit the potential for high-
density hare populations (Wolff 1980, p. 128). As a result, lynx
generally occur at relatively low densities in the contiguous United
States compared to the high lynx densities that occur in the northern
boreal forest of Canada (Aubry et al. 2000, pp. 375, 393-394) or to the
densities of species such as the bobcat, which is a habitat and prey
generalist.
[[Page 66940]]
Lynx are highly mobile and often move long distances (greater than
60 miles (mi) (100 kilometers (km))) during dispersal attempts (Aubry
et al. 2000, pp. 386-387; Mowat et al. 2000, pp. 290-294). Lynx
disperse primarily when snowshoe hare populations decline (Ward and
Krebs 1985, pp. 2821-2823; O'Donoghue et al. 1997, pp. 156, 159; Poole
1997, pp. 499-503). Sub-adult lynx disperse even when prey is abundant
(Poole 1997, pp. 502-503) because local home ranges with abundant hares
are generally occupied by established adult lynx and sub-adults must
look elsewhere to establish new home ranges. Lynx also make exploratory
movements outside their home ranges (Aubry et al. 2000, p. 386; Squires
et al. 2001, pp. 18-26).
The boreal forest landscape is naturally dynamic. Forest stands
within the landscape change as they undergo succession after natural or
human-caused disturbances such as fire, insect epidemics, wind, ice,
disease, and forest management (Elliot-Fisk 1988, pp. 47-48; Agee 2000,
pp. 47-69). As a result, lynx habitat within the boreal forest
landscape is typically patchy because the boreal forest contains stands
of differing ages and conditions, some of which are suitable as lynx
foraging or denning habitat (or will become suitable in the future due
to forest succession) and some of which serve as travel routes for lynx
moving between foraging and denning habitat (McKelvey et al. 2000c, pp.
427-434; Hoving et al. 2004, pp. 290-292).
Snowshoe hares comprise a majority of the lynx diet (Nellis et al.
1972, pp. 323-325; Brand et al. 1976, pp. 422-425; Koehler 1990, p.
848; Apps 2000, pp. 358-359, 363; Aubry et al. 2000, pp. 375-378; Mowat
et al. 2000, pp. 267-268; von Kienast 2003, pp. 37-38; Squires et al.
2004, p. 15, Table 8). When snowshoe hare populations are low, female
lynx produce few or no kittens that survive to independence (Nellis et
al. 1972, pp. 326-328; Brand et al. 1976, pp. 420, 427; Brand and Keith
1979, pp. 837-838, 847; Poole 1994, pp. 612-616; Slough and Mowat 1996,
pp. 953-958; O'Donoghue et al. 1997, pp. 158-159; Aubry et al. 2000,
pp. 388-389; Mowat et al. 2000, pp. 285-287). Lynx prey
opportunistically on other small mammals and birds, particularly during
lows in snowshoe hare populations, but alternate prey species may not
sufficiently compensate for low availability of snowshoe hares,
resulting in reduced reproductive success and reduced lynx populations
(Brand et al. 1976, pp. 422-425; Brand and Keith 1979, pp. 833-834;
Koehler 1990, pp. 848-849; Mowat et al. 2000, pp. 267-268).
In northern Canada, lynx populations fluctuate in response to the
cycling of snowshoe hare populations (Hodges 2000a, pp. 118-123; Mowat
et al. 2000, pp. 270-272). Although snowshoe hare populations in the
northern portion of their range show strong, regular population cycles,
these fluctuations are generally much less pronounced in the southern
portion of their range in the contiguous United States (Hodges 2000b,
pp. 165-173). In the contiguous United States, the degree to which
regional local lynx population fluctuations are influenced by local
snowshoe hare population dynamics is unclear. However, researchers
anticipated that, because of natural fluctuations in snowshoe hare
populations, there will be periods when lynx densities are extremely
low.
Because lynx population dynamics, survival, and reproduction are
closely tied to snowshoe hare availability, lynx habitat suitability is
directly tied to hare habitat quality. Lynx generally concentrate their
foraging and hunting activities in habitat patches where snowshoe hare
populations are high (Koehler et al. 1979, p. 442; Ward and Krebs 1985,
pp. 2821-2823; Murray et al. 1994, p. 1450; O'Donoghue et al. 1997, pp.
155, 159-160 and 1998, pp. 178-181). Snowshoe hares are most abundant
in forest stands with dense understories that provide forage, cover to
escape from predators, and protection during extreme weather (Wolfe et
al. 1982, pp. 665-669; Litvaitis et al. 1985, pp. 869-872; Hodges
2000a, pp. 136-140 and 2000b, pp. 183-195). Generally, hare densities
are higher in regenerating, earlier successional forest stages because
they have greater understory structure than mature forests (Buehler and
Keith 1982, p. 24; Wolfe et al. 1982, pp. 665-669; Koehler 1990, pp.
847-848; Hodges 2000b, pp. 183-195; Homyack 2003, pp. 63, 141; Griffin
2004, pp. 84-88). However, snowshoe hares can be abundant in mature
forests with dense understories (multi-storied stands) especially in
the Rocky Mountains (Griffin 2004, pp. 53-54, Squires et al. 2006, p.
15).
Within the boreal forest, lynx den sites are located where coarse
woody debris, such as downed logs and windfalls, provides security and
thermal cover for lynx kittens (McCord and Cardoza 1982, pp. 743-744;
Koehler 1990, pp. 847-849; Slough 1999, p. 607; Squires and Laurion
2000, pp. 346-347; Squires et al. 2008, p. 1503; Organ 2001). The
amount of structure (e.g., downed, large, woody debris) appears to be
more important than the age of the forest stand for lynx denning
habitat (Mowat et al. 2000, pp. 10-11); however, proximity to forest
stands with high horizontal cover (and presumably high snowshoe hare
density) does contribute to overall suitability of denning sites
(Squires et al. 2008, p. 1503).
The 14-State Canada Lynx DPS
The Service listed lynx in 2000 within what we determined to be the
contiguous United States DPS, which included the known current and
historical range of the lynx (68 FR 40080). In specifying where lynx
was listed, we used State boundaries to circumscribe the outer limits
in which the DPS was found at the time, using the best science
available. This range included portions of the States of Colorado,
Idaho, Maine, Minnesota, Montana, Washington, and Wyoming, and also
areas that could support dispersers - portions of the above States
along with portions of Michigan, New Hampshire, New York, Oregon, Utah,
Vermont, and Wisconsin (68 FR 40099). We did not consider other areas
outside of boreal forest, where dispersing lynx had only been
sporadically documented in the past, to be within the range of the
lynx, because we deemed these areas to be currently incapable of
supporting dispersing lynx. These areas included Connecticut, Indiana,
Iowa, Massachusetts, Nebraska, Nevada, North Dakota, Ohio,
Pennsylvania, South Dakota, and Virginia (68 FR 40099).
We did not include New Mexico in this list of States because no
lynx occurred there, and we had no information to indicate that lynx
had ever been documented there, even sporadically. Therefore, we
determined that the boundaries delineating the range of lynx did not
include New Mexico because it was not within the current or historical
range of the species (68 FR 40083). In addition, no review of potential
habitat in New Mexico was conducted. We did not consider lynx recently
released into Colorado that strayed into New Mexico as sufficient
reason to include New Mexico within the range of lynx because there was
no evidence that habitat in New Mexico historically supported lynx, or
that lynx moving into New Mexico would support maintenance of the lynx
DPS (68 FR 40083).
In 1998, when the Service proposed to list the lynx in the United
States, no wild (or reintroduced) lynx were known to exist in Colorado,
which represented the extreme southern edge of the species' range (65
FR 16059). Boreal forest habitat in Colorado and southeastern Wyoming,
the Southern Rocky Mountain Region, is isolated
[[Page 66941]]
from boreal forest in Utah and northwestern Wyoming by intervening
grassland and shrubland habitats, and is naturally highly fragmented
(65 FR 16059).
It was uncertain whether lynx records from Colorado represented a
small self-sustaining lynx population, or whether historical records
represented dispersers that arrived during high population cycles of
lynx and subsequently died out. Under the scenario whereby lynx in
Colorado were not a self-sustaining population, some of the dispersers
may have remained for a period of years if hare populations were high
enough to support residents and reproduction, but eventually succumbed
to a lack of consistent, high-quality habitat and food sources. We
believe that this is the most likely historical scenario in the
southern Rockies based on the small number of historic lynx records
(McKelvey et al. 2000a, pp. 229-231), low snowshoe hare densities
(Andersen et al. 1980, Table 5; Dolbeer and Clark 1975, p. 539; Hodges
2000b, Table 7.5; Malaney 2003, pp. 65, 87, 90; Zahratka and Shenk
2008, Table 4), and overall low reproductive output of the reintroduced
population (Shenk 2007, pp. 11-13).
In 1999, the Colorado Division of Wildlife (CDOW) reintroduced 22
wild lynx from Canada and Alaska into southwestern Colorado (Shenk
2007, p. 20). By 2003, when we clarified the listing rule (68 FR 40076,
July 3, 2003), no data indicated that the lynx released could be
supported by the habitat available in Colorado. In their 2007 Wildlife
Research Report, CDOW continued to conclude that ``what is yet to be
determined is whether current conditions in Colorado can support the
recruitment necessary to offset annual mortality in order to sustain
the population'' (Shenk 2007, p. 18). Colorado was included in the 14-
State DPS in 2000, because records indicated that lynx were documented
there historically; however, it was not known whether the habitat
occurred in the requisite quantity and quality to sustain lynx
populations. Therefore, the 2000 listing represented a conservative
approach, which included areas in the range of the species when
evidence of long-term persistence was lacking, but enough evidence
existed that it could not be discounted.
In 2000, when the final listing rule was published, we were not
aware of any information to indicate that lynx existed in New Mexico,
that it was ever occupied historically, or that it could sustain lynx.
As a consequence, we did not include New Mexico in the listing rule or
special rule concerning lynx in the contiguous 14-State DPS. We now
have documentation that lynx reintroduced in Colorado have attempted to
disperse in many directions, primarily into New Mexico, Utah, and
Wyoming, but also into eight other States (Shenk 2007, pp. 6, 9). No
reproduction has been documented in New Mexico or Utah, but one den was
found in Wyoming (Shenk 2007, p. 15), and one den was found within 5.6
mi (9 km) of the Colorado-New Mexico State boundary (Shenk 2009b,
entire).
We also point out that lynx dispersal away from the reintroduction
area in southern Colorado is what would be predicted if lynx were
reintroduced into an area that consisted mostly of unsuitable habitat,
and dispersing animals were searching for habitats with the requisite
prey densities that could support resident animals. Our review of the
evidence indicates that this habitat is most likely found north of the
southern Rockies.
We included an analysis in the final lynx listing rule (68 FR
40081) on whether lynx were both discrete and significant in each of
the four regions of the contiguous United States where it exists (the
Northeast, Great Lakes, Southern Rocky Mountains, and Northern Rocky
Mountains/Cascades). We determined that none of the regions
individually constitute significantly unique or unusual ecological
settings and, therefore, did not individually meet the DPS criteria.
Therefore, the lynx was listed as a single contiguous United States DPS
defined by 14 States.
Lynx in the Southern Rockies
Lynx reintroduction into the southern Rocky Mountains in southern
Colorado occurred between 1999 and 2006 with a total of 218 animals
released (Shenk 2008, p. 1). Reintroduced lynx were captured from the
wild in Alaska and Canada. Also in 1999, the CDOW began a post-release
monitoring program that tracked reintroduced animals (and,
opportunistically, their wild-born progeny). The purpose of the
monitoring program was to determine whether the reintroduced population
was reproducing and to collect habitat use and other ecological data.
Prior to beginning reintroductions, CDOW reviewed the historic evidence
of lynx occupation and concluded that the Southern Rockies in Colorado
represent the extreme southern edge of the range of lynx. At that time,
lynx were either extirpated or at such low densities that the extant
population was no longer viable (Seidel et al. 1998, p. 4). Throughout
the post-release monitoring program, CDOW has maintained that the
reintroduction is experimental in nature and that it remains to be
determined whether the southern Rockies can support enough lynx
reproduction to offset mortality (Shenk 2007, p. 18)
At the time of the lynx listing in 2000, the CDOW reintroduction
program was in its beginning stages and without post-release data or
analysis to evaluate its effectiveness. Consequently, when lynx were
listed, lynx released into Colorado, prior to and after the listing,
received the full protection of the Act as a threatened species. At
that time, it was our determination that habitat in Colorado
represented the southernmost extension of lynx range (65 FR 16052, p.
16059), based on the lack of historic lynx records in New Mexico.
Therefore, when the line demarcating the range of lynx (and
consequently the regulatory reach of the final listing rule) was placed
at the border of Colorado and New Mexico, it was thought that this
boundary placement conservatively encompassed all of the lynx range in
the southern Rocky Mountains, and that while lynx may occasionally
wander south of that line, such occurrences would be rare (68 FR 40076,
p. 40077).
Habitat in New Mexico that may support all or a portion of lynx
life-history needs is limited to the San Juan and Sangre de Cristo
mountains in the northern part of the State. Both of these ranges are
contiguous with mountains in Colorado where reintroduced lynx are
residing and have reproduced. Both of these mountain ranges have
snowshoe hares (Malaney and Frey 2006, p. 879); however, densities at
the landscape scale (i.e., the scale of a lynx home range) are low
(0.13 hares/ha (0.32 hares/ac) before seasonal recruitment) and are
likely not high enough to support resident lynx (Malaney 2003, pp. 65,
87, 90).
Most of the habitat in question is managed by the Carson and Santa
Fe National Forests of the U.S. Forest Service (USFS). Approximately
596,000 ac (241,193 ha) of spruce-fir forest types lie within this
area, 440,000 ac of which are on National Forest system lands (USFS
2009, pp. 5-6). On the Carson and Santa Fe National Forests,
approximately 536,400 ac (217,073 ha) have characteristics of potential
lynx habitat (spruce fir and other cold, wet conifer forest types),
about 45 percent of which occurs in designated wilderness (USFS 2009,
p. 7). As a reference, in the reintroduced Colorado lynx population the
average lynx home range size is 108,109 ac (43,750 ha) (calculated from
data in Shenk 2007, p. 11). Other small patches of isolated spruce-fir
and mixed conifer habitats occur in northern New Mexico, but due to
their small size, they are not considered to have any value as lynx
habitats (USFS 2009, p. 7). In their
[[Page 66942]]
information submitted for this finding, the USFS concluded that due to
the lack of historic record, lack of reproduction in reintroduced lynx,
low prey densities, high densities of competitor species and relatively
low snow levels for this area, New Mexico is likely to function as a
``sink'' habitat for the reintroduced lynx population in the southern
Rockies meaning that mortality would exceed recruitment in this area
(USFS 2009, p. 17).
As explained in our 2007 clarification of the 2000 listing rule (72
FR 1186, p. 1189), the presence of snowshoe hares at high population
densities is a pre-requisite for lynx residency in any area. However,
neither the presence of snowshoe hare populations nor contiguity with a
lynx population are sufficient to assure that lynx will reside in an
area that lacks a high density of snowshoe hares at a scale large
enough to support a lynx home range (landscape scale). Snowshoe hare
habitat is of varying quality, and in the lower-48 States only the
highest quality habitat (i.e., that with the highest snowshoe hare
densities) is capable of supporting lynx populations and contributing
to the maintenance of the DPS. Since long-term studies of snowshoe hare
densities across the range of the DPS have not occurred, we believe
that historic and recent data about where lynx have or do reside and
reproduce, provide the best available scientific data concerning which
areas have the requisite high hare densities and amount of habitat
required to support lynx.
The best source of lynx presence data for the historic period is
McKelvey et al. (2000b entire). McKelvey et al. (2000b, entire) focus
on the use of ``verifiable records'' as the most appropriate locality
records for lynx. Verifiable records are those for which there is
verifiable evidence that the animal in question was a lynx, such as a
museum specimen, a diagnostic photograph, or an expert that had the
animal ``in hand'' at the time of identification. We believe that the
need for accurate identification of lynx necessitates that only
verifiable records be used, and we refer readers to McKelvey et al.
(2008, entire) for a discussion of evidentiary standards. Others have
attempted to determine the historic range of lynx through the use of
other types of evidence. Frey (2006, entire) used a combination of
habitat associations, biogeography, and habitat contiguity with known
populations to infer lynx historic range to areas without historic
records.
While this method may point to areas that were potentially in the
range of the species, it presumes that we understand the species' life-
history needs and the habitat condition well enough to know if the
habitat in question would support the species. In the case of lynx, we
know that lynx are dependent on high-density snowshoe hare populations,
in the sense that we know of no lynx population that occurs in an area
without a high density of hares. Conversely, we do know of habitats
with low-density hare populations that have no lynx populations, such
as the Olympic Peninsula in Washington, southwestern Montana/central
Idaho, and much of Appalachia (Hall 1981, p. 317). We do not know what
the threshold landscape-scale hare density is that will allow lynx to
persist, or precisely what habitat characteristics allow persistence of
reproducing populations.
Many depictions of lynx geographic range simply draw lines around
peripheral occurrence records without reference to habitat (e.g., Hall
1981). These depictions are likely to over-estimate the extent of lynx
range due to the animal's tendency to move long distances across
unsuitable habitats while attempting to disperse. Attempted dispersal
forays also bring lynx into human-dominated landscapes where they are
disproportionately likely to experience mortality in a way that leads
to discovery by humans and thus these animals are disproportionately
likely to become locality records. We believe that the best available
scientific information to inform determinations about historic range is
verifiable occurrence records due to their high level of reliability.
Verifiable species records, put in the context of suitable habitat
distribution, are crucial to determining what the historic distribution
of a species was, especially when there is some doubt about the habitat
characteristics that are sufficient to support the species. By using
verifiable occurrence records, we essentially give lynx a vote in the
process, where scientific uncertainty does not permit us to determine
precisely where suitable habitat exists. For these reasons, we believe
that lynx geographic range is best depicted through a combination of
reliable occurrence records and suitable habitat. Because lynx have a
tendency to move long distances during unsuccessful dispersal attempts,
the actual range of the species is much smaller than what is depicted
on range maps that simply draw lines around peripheral occurrence
records and do not consider habitat type and quality. For examples of
analyses that use both occurrence records and suitable habitat to
determine where a species may have occurred in the past, see McKelvey
et al. (2000b, entire) and Aubry et al. (2007, entire).
In our 2007 clarification of the 2000 listing rule, we further
determined that the northern Rockies and North Cascades formed a
significant portion of the DPS' range because this geographic area and
its constituents (e.g., habitat) was the primary region necessary to
support the long-term existence of the contiguous U.S. DPS (72 FR 1186,
p. 1189). This finding was based on the remaining portions of the DPS
range being composed of marginal habitat where lynx presence was tied
more directly to immigration of lynx from Canada. In that document we
emphasized that, just because habitat is marginal, it does not mean
that lynx can no longer live there. Instead, marginal habitat means
that such areas cannot and may never have supported resident lynx
populations (72 FR 1186, p. 1188).
Data collected by CDOW during their post-release monitoring also
are valuable in determining where lynx may find snowshoe hare densities
that may (at least occasionally) support reproduction. Between
September 1999 and March 2007, 60 individual lynx (37 females, 23
males) crossed into New Mexico (Shenk 2007, p. 10). Many of these lynx
passed back into Colorado after short forays into New Mexico, 14
mortalities occurred, and some lynx may have resided in New Mexico
year-round, although that has not been documented (Shenk 2007, pp. 10-
26). From September 1999 through March 2007, CDOW found no evidence
that any of the 37 female lynx that have moved into New Mexico
reproduced or attempted to reproduce (Shenk 2007, p. 15). However, CDOW
does not monitor lynx that leave the State of Colorado as intensively
as it does in Colorado. Based on the large number of female lynx that
have moved into New Mexico over the period of the reintroduction
program without evidence of any reproduction, we cannot conclude that
New Mexico lynx habitat is of high enough quality to support a resident
population. Indeed, we share CDOW's concern that the southern Rockies
in their entirety may not be able to sustain a lynx population.
Lynx suffer proportionally higher mortality in New Mexico than in
other States (Shenk 2001, p. 14). However, statistical tests to
determine whether this difference was significantly different than what
might be expected by chance were not reported. In addition, lynx
mortality due to deliberate killing (shooting) was higher as a
proportion of all mortalities in Colorado (53.8 percent) (where all
lynx are protected by the Act) than they were outside Colorado (46.2
percent) (where
[[Page 66943]]
lynx have Act protections in some States but not New Mexico and others)
(Shenk 2007, Table 9). Therefore, the evidence presented by Shenk does
not indicate that lack of the Act's protections in New Mexico is a
significant contributor to lynx mortality. Rather, lynx mortality is
high for lynx that disperse outside of high-quality lynx habitat
whether they remain under the protection of the Act or not. This result
is to be expected, because dispersal outside of quality habitat is
usually only done under stress, such as inability to find food or
displacement by another lynx. Dispersal outside of lynx habitat is
likely to place lynx in human-dominated landscapes such as agricultural
areas, settlements, and transportation corridors, where lynx
mortalities are more likely to occur.
It is our determination, based on the historic lack of evidence of
lynx occurrence in New Mexico (McKelvey et al. 2000a, Table 8.1) and
the recent evidence of lynx dispersal attempts into northern New Mexico
(Shenk 2007, pp. 29-31), that lynx in New Mexico represent attempted
dispersers, rather than lynx establishing residency in suitable habitat
as defined in our clarification of findings (68 FR 40076, p. 40077). We
also believe that the habitat in New Mexico is a population ``sink'',
in that it is unlikely to support lynx reproduction to the extent that
recruitment will ever be able to offset population mortality, even
absent any human-caused mortality. However, as we stated in 2003, at
the time of listing we considered lynx found in population sinks such
as New Mexico to be dispersers but we included these areas within the
range of lynx (68 FR 40076, p. 40080).
Finding
We have carefully assessed the information in the petition along
with the best scientific and commercial data available. This 12-month
finding reflects and incorporates information that we received during
the public comment period or that we obtained through consultation,
literature research, and field visits.
On the basis of this review, we have determined that revising the
boundaries of the DPS as identified in the 2000 final listing rule for
Canada lynx to include New Mexico is warranted. This finding is based
on the fact that the information that we used to describe the southern
boundary of the DPS at the time of listing is out of date. Lynx that
attempt to disperse outside of areas that support populations should be
protected from direct or indirect mortality that may occur due to the
lack of protections under the Act.
We are assigning a listing priority number (LPN) of 12 to amending
the listing of lynx to include New Mexico in the listed DPS. We assign
an LPN of 1 to 12 (higher number being of lower priority), depending on
the magnitude of threats (high vs. moderate to low), immediacy of
threats (imminent or nonimminent), and taxonomic status of the species
(in order of priority: monotypic genus (a species that is the sole
member of a genus); species; or part of a species (subspecies, DPS, or
significant portion of the range)). We are assigning an LPN of 12 based
on nonimminent threats of a low magnitude to the lynx DPS occurring
from human-caused mortality to lynx dispersing to New Mexico and the
lack of protection under the Act for these lynx. Human-caused mortality
is a factor affecting lynx in New Mexico; however, this impact does not
occur at a level such that it creates a significant threat to lynx in
the contiguous United States and to the DPS as a whole. The magnitude
of threats to the lynx DPS, inclusive of those lynx in New Mexico, is
low. The threats occur infrequently and are nonimminent. Furthermore,
as described above, the amount of suitable habitat for lynx in New
Mexico is considered negligible relative to the amount of habitat
within the listed range. Potential impacts to the habitat have not been
documented to threaten lynx, either in New Mexico or outside of it. The
majority of lynx and its habitats within the DPS are already protected
by the Act. Because lynx in the lower 48 States are listed as a DPS,
the appropriate LPN for this level of magnitude and immediacy of
threats is a 12.
Emergency Listing
We may list a species effective immediately under Section 4 of the
Act if there is any emergency posing a significant risk to the well-
being of the species. Because threats identified to lynx in New Mexico
are determined to be nonimminent and of low magnitude for the species
in the lower 48 States (DPS) as a whole, the Secretary has determined
not to exercise his discretion to invoke the provisions to immediately
put the protections of the Act in place for the Canada lynx in New
Mexico.
Importance of Habitat in New Mexico for the Lynx DPS
The information gathered in the process of preparing this finding
does not indicate that New Mexico can support reproducing lynx. We
still find no evidence that New Mexico can support a lynx population or
that habitat in New Mexico may play a supporting role in conservation
of the DPS. We believe that the only role that habitat in New Mexico
may play in lynx conservation is to allow individuals to survive long
enough to move north back into more suitable habitat. Managing to
increase habitat suitability for lynx in New Mexico would be counter-
productive to this end, because it is unlikely that habitat in New
Mexico can be made to support lynx, and the important goal is that lynx
return to the population further north. Therefore, we do not recommend
that habitat in New Mexico be managed to support residency and
reproduction, as are habitats further north in Colorado and the
northern Rockies. For example, we do not think it would be appropriate
for the USFS to implement management based on the Lynx Conservation
Assessment and Strategy such as that found in the Southern Rocky
Mountain Lynx Amendment (USFS 2008).
Significant Portion of the Range
Under the Act and our implementing regulations, a species may
warrant listing if it is threatened or endangered in a significant
portion of its range. Because this 12-month finding to amend the
listing of the Canada lynx DPS is warranted but precluded, we do not
need to perform a ``significant portion of the range'' analysis for the
species at this time.
Preclusion and Expeditious Progress
Preclusion is a function of the listing priority of a species in
relation to the resources that are available and competing demands for
those resources. Thus, in any given FY, multiple factors dictate
whether it will be possible to undertake work on a proposed listing
regulation or whether promulgation of such a proposal is warranted but
precluded by higher-priority listing actions.
The resources available for listing actions are determined through
the annual Congressional appropriations process. The appropriation for
the Listing Program is available to support work involving the
following listing actions: Proposed and final listing rules; 90-day and
12-month findings on petitions to add species to the Lists of
Endangered and Threatened Wildlife and Plants (Lists) or to change the
status of a species from threatened to endangered; annual
determinations on prior ``warranted but precluded'' petition findings
as required under section 4(b)(3)(C)(i) of the Act; critical habitat
petition findings; proposed and
[[Page 66944]]
final rules designating critical habitat; and litigation-related,
administrative, and program-management functions (including preparing
and allocating budgets, responding to Congressional and public
inquiries, and conducting public outreach regarding listing and
critical habitat). The work involved in preparing various listing
documents can be extensive and may include, but is not limited to:
gathering and assessing the best scientific and commercial data
available and conducting analyses used as the basis for our decisions;
writing and publishing documents; and obtaining, reviewing, and
evaluating public and peer review comments on proposed rules and
incorporating relevant information into final rules. The number of
listing actions that we can undertake in a given year also is
influenced by the complexity of those listing actions; that is, more
complex actions generally are more costly. For example, during the past
several years, the cost (excluding publication costs) for preparing a
12-month finding, without a proposed rule, has ranged from
approximately $11,000 for one species with a restricted range and
involving a relatively uncomplicated analysis, to $305,000 for another
species that is wide-ranging and involved a complex analysis.
We cannot spend more than is appropriated for the Listing Program
without violating the Anti-Deficiency Act (see 31 U.S.C. Sec.
1341(a)(1)(A)). In addition, in FY 1998 and for each FY since then,
Congress has placed a statutory cap on funds that may be expended for
the Listing Program, equal to the amount expressly appropriated for
that purpose in that FY. This cap was designed to prevent funds
appropriated for other functions under the Act (for example, recovery
funds for removing species from the Lists), or for other Service
programs, from being used for Listing Program actions (see House Report
105-163, 105th Congress, 1st Session, July 1, 1997).
Recognizing that designation of critical habitat for species
already listed would consume most of the overall Listing Program
appropriation, Congress also put a critical habitat subcap in place in
FY 2002, and has retained it each subsequent year to ensure that some
funds are available for other work in the Listing Program: ``The
critical habitat designation subcap will ensure that some funding is
available to address other listing activities'' (House Report No. 107-
103, 107th Congress, 1st Session, June 19, 2001). In FY 2002 and each
year until FY 2006, the Service has had to use virtually the entire
critical habitat subcap to address court-mandated designations of
critical habitat. Consequently, none of the critical habitat subcap
funds have been available for other listing activities. In FY 2007, we
were able to use some of the critical habitat subcap funds to fund
proposed listing determinations for high-priority candidate species. In
FY 2008 and 2009, while we were unable to use any of the critical
habitat subcap funds to fund proposed listing determinations, we did
use some of this money to fund the critical habitat portion of some
proposed listing determinations, so that the proposed listing
determination and proposed critical habitat designation could be
combined into one rule, thereby being more efficient in our work. In FY
2010, we anticipate being able to do the same.
Thus, through the listing cap, the critical habitat subcap, and the
amount of funds needed to address court-mandated critical habitat
designations, Congress and the courts have in effect determined the
amount of money available for other listing activities. Therefore, the
funds in the listing cap, other than those needed to address court-
mandated critical habitat for already-listed species, set the limits on
our determinations of preclusion and expeditious progress.
Congress also recognized that the availability of resources was the
key element in deciding, when making a 12-month petition finding,
whether we would prepare and issue a listing proposal or instead make a
``warranted but precluded'' finding for a given species. The Conference
Report accompanying Public Law 97-304, which established the current
statutory deadlines for listing and the warranted-but-precluded finding
requirements that are currently contained in the Act, states (in a
discussion on 90-day petition findings that by its own terms also
covers 12-month findings) that the deadlines were ``not intended to
allow the Secretary to delay commencing the rulemaking process for any
reason other than that the existence of pending or imminent proposals
to list species subject to a greater degree of threat would make
allocation of resources to such a petition [i.e., for a lower-ranking
species] unwise.''
In FY 2010, expeditious progress is that amount of work that can be
achieved with $10,471,000, which is the amount of money that Congress
appropriated for the Listing Program (that is, the portion of the
Listing Program funding not related to critical habitat designations
for species that are already listed). Our process is to make our
determinations of preclusion on a nationwide basis to ensure that the
species most in need of listing will be addressed first and also
because we allocate our listing budget on a nationwide basis. The
$10,471,000 will be used to fund work in the following categories:
compliance with court orders and court-approved settlement agreements
requiring that petition findings or listing determinations be completed
by a specific date; section 4 (of the Act) listing actions with
absolute statutory deadlines; essential litigation-related,
administrative, and listing program-management functions; and high-
priority listing actions for some of our candidate species. The
allocations for each specific listing action are identified in the
Service's FY 2009 Allocation Table (part of our administrative record).
For FY 2010, Congress recently passed an appropriations bill. We are
working on finalizing our allocation of money for specific listing
actions.
In FY 2007, we had more than 120 species with an LPN of 2, based on
our September 21, 1983, guidance for assigning an LPN for each
candidate species (48 FR 43098). Using this guidance, we assign each
candidate an LPN of 1 to 12, depending on the magnitude of threats
(high vs. moderate to low), immediacy of threats (imminent or
nonimminent), and taxonomic status of the species (in order of
priority: monotypic genus (a species that is the sole member of a
genus); species; or part of a species (subspecies, DPS, or significant
portion of the range)). The lower the listing priority number, the
higher the listing priority (that is, a species with an LPN of 1 would
have the highest listing priority). Because of the large number of
high-priority species, we further ranked the candidate species with an
LPN of 2 by using the following extinction-risk type criteria:
International Union for the Conservation of Nature and Natural
Resources (IUCN) Red list status/rank, Heritage rank (provided by
NatureServe), Heritage threat rank (provided by NatureServe), and
species currently with fewer than 50 individuals, or 4 or fewer
populations. Those species with the highest IUCN rank (critically
endangered), the highest Heritage rank (G1), the highest Heritage
threat rank (substantial, imminent threats), and currently with fewer
than 50 individuals, or fewer than 4 populations, comprised a group of
approximately 40 candidate species (``Top 40''). These 40 candidate
species have had the highest priority to receive funding to work on a
proposed listing determination. As we work on proposed and final
listing rules for these 40
[[Page 66945]]
candidates, we are applying the ranking criteria to the next group of
candidates with LPNs of 2 and 3 to determine the next set of highest
priority candidate species. In FY 2008-2009, we funded work on proposed
listing determinations for 61 candidate species, most of which have an
LPN of 2, although these have not been published to date. There are
currently 56 candidate species with an LPN of 2 that nave not received
funding for preparation of proposed listing rules.
To be more efficient in our listing process, as we work on proposed
rules for these species in the next several years, we are preparing
multi-species proposals when appropriate, and these may include species
with lower priority if they overlap geographically or have the same
threats as a species with an LPN of 2. In addition, available staff
resources also are a factor in determining high-priority species
provided with funding. Finally, proposed rules for reclassification of
threatened species to endangered are lower priority, since as listed
species, they are already afforded the protection of the Act and
implementing regulations.
Our decision that a proposed rule to revise the boundaries of the
Canada lynx DPS under the Act is warranted but precluded is based on
the low magnitude and non-imminence of threats to the Canada lynx in
the lower 48-contiguous States (i.e., the DPS). As we have already
determined that the potential threats are of low magnitude and are not
imminent, we conclude that this action should receive the lowest
listing priority. We consider the priority for amending the Canada lynx
DPS to be lower than for other candidate species in need of protection
under the Act. As described in the ``Finding'' section above, we have
assigned an LPN of 12 to this amendment. In accordance with guidance we
published on September 21, 1983, we assign an LPN to each candidate
species (48 FR 43098). Such a priority ranking guidance system is
required under section 4(h)(3) of the Act (16 U.S.C. 1533(h)(3)). Using
this guidance, we assign each candidate an LPN of 1 to 12, depending on
the magnitude of threats, imminence of threats, and taxonomic status;
the lower the listing priority number, the higher the listing priority,
i.e., a species with an LPN of 1 would have the highest listing
priority. We currently have 56 species with an LPN of 2 that have not
received funding yet (see Table 1 of the November 9, 2009, Notice of
Review; 74 FR 57866). For the next 2 years, we have funded proposed
listings for several species with an LPN of 2. We consider amending the
Canada lynx DPS to be precluded by these high-priority candidate
species.
As explained above, a determination that listing is warranted but
precluded also must demonstrate that expeditious progress is being made
to add or remove qualified species to and from the Lists of Endangered
and Threatened Wildlife and Plants. (Although we do not discuss it in
detail here, we also are making expeditious progress in removing
species from the list under the Recovery Program, which is funded by a
separate line item in the budget of the Endangered Species Program. As
explained above in our description of the statutory cap on Listing
Program funds, the Recovery Program funds and actions supported by them
cannot be considered in determining expeditious progress made in the
Listing Program.) As with our ``precluded'' finding, expeditious
progress in adding qualified species to the Lists is a function of the
resources available and the competing demands for those funds. Given
that limitation, we find that we made progress in FY 2009 in the
Listing Program and will continue to make progress in FY 2010. This
progress included preparing and publishing the following
determinations:
