SUPPLEMENTARY INFORMATION: This
document consists of: (1) A proposed
rule to list the Coral Pink Sand Dunes
(CPSD) tiger beetle as threatened; and
(2) a proposed critical habitat
designation for the CPSD tiger beetle.
Executive Summary
Why we need to publish a rule. Under
the Act, if a species is determined to be
an endangered or threatened species
throughout all or a significant portion of
its range, we are required to promptly
publish a proposed rule in the Federal
Register and make a determination on
our proposal within one year. Critical
habitat shall be designated, to the
maximum extent prudent and
determinable, for any species
determined to be an endangered or
threatened species under the Act.
Listing a species as an endangered or
threatened species and designations and
revisions of critical habitat can only be
completed in a rule making process.
What This Rule Will Do
• We are proposing to list the CPSD
tiger beetle as a threatened species.
• We also are proposing to designate
921 hectares (2,276 acres) of the Coral
Pink Sand Dunes (CPSD) Geologic
Feature in Kane County as critical
habitat.
The basis for our action. Under the
Act, we can determine that a species is
an endangered or threatened species
based on any of five factors: (A) The
present or threatened destruction,
modification, or curtailment of its
habitat or range; (B) Overutilization for
commercial, recreational, scientific, or
educational purposes; (C) Disease or
predation; (D) The inadequacy of
existing regulatory mechanisms; or (E)
PO 00000
Frm 00002
Fmt 4701
Sfmt 4702
Other natural or manmade factors
affecting its continued existence.
We propose to list the CPSD tiger
beetle as a threatened species because of
the following threats:
• Habitat loss and degradation caused
by off-road vehicle use.
• Small population effects, such as
vulnerability to random chance events.
• Other natural or manmade factors,
including climate change and drought.
• Cumulative interaction of
individual factors such as off-road
vehicle use, climate change, and
drought.
We have also determined that existing
regulatory mechanisms are not
adequately addressing the threats to the
species.
Under the Act, any species that is
determined to be a threatened or
endangered species shall, to the
maximum extent prudent and
determinable, have habitat designated
that is considered to be critical habitat.
Section 4(b)(2) of the Endangered
Species Act states that the Secretary
shall designate critical habitat on the
basis of the best available scientific data
after taking into consideration the
economic impact, national security
impact, and any other relevant impact of
specifying any particular area as critical
habitat.
We propose to designate a 921-hectare
(2,276-acre) area as critical habitat for
the CPSD tiger beetle. The critical
habitat area we propose in this rule
constitutes our current best assessment
of the specific areas that meet the
definition of critical habitat for the
CPSD tiger beetle.
We are preparing an economic
analysis of the proposed designation of
critical habitat. In order to consider
economic impacts, we are preparing an
analysis of the potential economic
impacts of the proposed critical habitat
designations. We will use the
information from the draft economic
analysis to inform the development of
the final designation of critical habitat
for this species.
We are preparing an environmental
assessment of the proposed designation
of critical habitat. Based on a relevant
court decision in the Tenth Circuit, we
shall evaluate the potential
environmental impacts of a designation
of critical habitat for any species whose
range overlaps the geographic area
governed by the Federal Tenth Circuit
Court under the National Environmental
Policy Act (NEPA). We will use the
results of the draft environmental
assessment to inform the development
of our final designation of critical
habitat.

We will seek peer review. We are
seeking the expert opinions of
appropriate and independent specialists
regarding this proposed rule to ensure
that our decisions are based on
scientifically sound data, assumptions,
and analysis. We have invited these
peer reviewers to comment during the
proposed rule’s public comment period.
We will consider all comments and
information received during the
comment period in our preparation of
the final determinations. Accordingly,
the final decisions may differ from this
proposal.
Information Requested
We intend that any final action
resulting from this proposed rule will be
based on the best scientific and
commercial data available and be as
accurate and as effective as possible.
Therefore, we request comments or
information from the public, other
concerned governmental agencies,
Native American Tribes, the scientific
community, industry, or any other
interested parties concerning this
proposed rule. We particularly seek
comments concerning:
(1) The species’ biology, range, and
population trends, including:
(a) Habitat requirements for feeding,
breeding, and sheltering;
(b) Genetics and taxonomy;
(c) Historical and current range
including distribution patterns;
(d) Historical and current population
levels, and current and projected trends;
and
(e) Past and ongoing conservation
measures for the species, its habitat or
both.
(2) The factors that are the basis for
making a listing determination for a
species under section 4(a) of the Act (16
U.S.C. 1531 et seq.), which are:
(a) The present or threatened
destruction, modification, or
curtailment of its habitat or range;
(b) Overutilization for commercial,
recreational, scientific, or educational
purposes;
(c) Disease or predation;
(d) The inadequacy of existing
regulatory mechanisms; or
(e) Other natural or manmade factors
affecting its continued existence.
(3) Biological, commercial, or other
relevant data concerning any threats (or
lack thereof) to this species and existing
regulations that may be addressing those
threats.
(4) Additional information concerning
the historical and current status, range,
distribution, and population size of this
species, including the locations of any
additional populations of this species.
(5) The reasons why we should or
should not designate specific areas as
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
‘‘critical habitat’’ under section 4 of the
Act (16 U.S.C. 1531 et seq.) including
whether the degree of threats would be
expected to increase due to the
designation, and whether that increase
in threat outweighs the benefit of
designation such that the designation of
critical habitat may not be prudent.
(6) Specific information on our
proposed critical habitat designation:
(a) The amount and distribution of
CPSD tiger beetle habitat;
(b) What may constitute ‘‘physical or
biological features essential to the
conservation of the species,’’ within the
geographical range currently occupied
by the species;
(c) Where these features are currently
found;
(d) Whether any of these features may
require special management
considerations or protection;
(e) What areas, that were occupied at
the time of listing (or are currently
occupied) and that contain features
essential to the conservation of the
species, should be included in the
designation and why;
(f) What areas not occupied at the
time of listing are essential for the
conservation of the species and why.
(7) Land use designations and current
or planned activities in the areas
occupied by the species or proposed to
be designated as critical habitat, and
possible impacts of these activities on
this species and proposed critical
habitat.
(8) Information on the projected and
reasonably likely impacts of climate
change on the CPSD tiger beetle and
proposed critical habitat.
(9) Any foreseeable economic,
national security, or other relevant
impacts that may result from
designating any area that may be
included in the final designation. We
are particularly interested in any
impacts on small entities, and the
benefits of including or excluding areas
from the proposed designation that are
subject to these impacts.
(10) Whether our approach to
designating critical habitat could be
improved or modified in any way to
provide for greater public participation
and understanding, or to assist us in
accommodating public concerns and
comments.
(11) The likelihood of adverse social
reactions to the designation of critical
habitat and how the consequences of
such reactions, if likely to occur, would
relate to the conservation and regulatory
benefits of the proposed critical habitat
designation.

Previous Federal Actions
In 1984, we published our
Invertebrate Notice of Review
classifying the CPSD tiger beetle as a
Category 2 species (49 FR 21664, May
22, 1984). Category 2 status included
those taxa for which information in the
Service’s possession indicated that a
proposed rule was possibly appropriate,
but for which sufficient data on
biological vulnerability and threats were
not available to support a proposed
listing rule. In 1994, the Southern Utah
Wilderness Alliance petitioned us to list
the CPSD tiger beetle as an endangered
species and to designate critical habitat.
In our 90-day petition finding (59 FR
47293, September 15, 1994), we
indicated the petition presented
substantial information in support of
listing, and later that year we changed
the CPSD tiger beetle’s status from
Category 2 to Category 1 (59 FR 58982,
November 15, 1994). Category 1 status
E:\FR\FM\02OCP3.SGM
02OCP3
60210
Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
included those taxa for which the
Service had sufficient information on
biological vulnerability and threats to
support proposals to list them as
endangered or threatened species. On
December 5, 1996 (61 FR 64481), we
published our decision to discontinue
candidate categories and to restrict
candidate status to those taxa for which
we have sufficient information to
support issuance of a proposed rule. As
a result, the CPSD tiger beetle remained
a candidate species (62 FR 49398,
September 19, 1997).
In 1997, the Service, Bureau of Land
Management (BLM), Utah Department of
Natural Resources (UDNR), and Kane
County signed a Candidate Conservation
Agreement (CCA) and formed a
conservation committee with the dual
goals of protecting CPSD tiger beetle
habitat and balancing the needs of this
rare species with off-road vehicle (ORV)
use in the area (Conservation Committee
1997, pp. 4–5). These agencies renewed
the CCA in 2009 (Conservation
Committee 2009, entire). Coordination
under the CCA resulted in the
establishment of two Conservation
Areas that protect the CPSD tiger beetle
from ORV use—Conservation Areas A
and B (see Habitat and Factor A for
more information on the Conservation
Areas).
In our 2010 Candidate Notice of
Review, we identified the CPSD tiger
beetle as a species for which listing as
an endangered or threatened species
was warranted (with a listing priority
number of 2) but precluded by our work
on higher priority listing actions (75 FR
69222, November 10, 2010). In the 2011
Candidate Notice of Review, we
announced that we were not updating
our assessment for this species, because
we received funding to develop this
proposed listing rule (76 FR 66370,
October 26, 2011).

Background
Taxonomy and Species Description
The CPSD tiger beetle is a member of
the family Cicindelidae and genus
Cicindela. There are 109 species of tiger
beetles in the genus Cicindela in the
United States and Canada (Pearson et al.
2006, p. 4). The CPSD tiger beetle occurs
only at the CPSD geologic feature in
southern Utah and is separated from its
closest related subspecies, C. theatina,
by over 600 kilometers (km) (378 miles
(mi)) (Rumpp 1961, p. 182). It shares the
typical characteristics of other members
of the maritima group (a group of
closely related species of sand dune
tiger beetles) and is most similar in
morphology to other subspecies of
Cicindela limbata (no common name). It
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
was originally described as C. limbata
albissima (Rumpp 1961, p. 181).
However, more recent genetic analysis
revealed that the CPSD tiger beetle is
different from all other members in the
maritima group; consequently, we now
consider it a distinct species, CPSD tiger
beetle (Morgan et al. 2000, p. 1111).
This is the accepted taxonomic
classification (Pearson et al. 2006, p.
77).
CPSD tiger beetle adults are 11 to 15
millimeters (0.4 to 0.6 inches (in)) in
size and have striking coloration. The
large wing cases (known as elytra) are
predominantly white except for a thin
reddish band that runs down the length
of the center. Much of the body and legs
are covered in white hairs. The upper
thorax (middle region) has a metallic
sheen, and the eyes are particularly
large (Pearson et al. 2006, p. 77).
Habitat
Tiger beetle species occur in many
different habitats, including riparian
habitats, beaches, dunes, woodlands,
grasslands, and other open areas
(Pearson et al. 2006, p. 177). Most tiger
beetle species are habitat-specific and
consequently are useful as indicators of
habitat quality (Knisley and Hill 1992,
p. 140). The CPSD tiger beetle, like its
close relatives from the Great Sand
Dunes of Colorado (Cicindela theatina)
and the St. Anthony Dunes of Idaho (C.
arenicola), is restricted to sand dune
habitat.
The species’ current range extends
along the CPSD geologic feature. The
CPSD is a geologic feature named for the
deep pink color of its sand dunes (Ford
et al. 2010, p. 380). The CPSD are
located 5 km (3.1 mi) north of the UtahArizona state line and 43 km (27 mi)
west of Kanab, Utah (see Figure 1 below
in Population Distribution). The CPSD
are about 13 km (8 mi) long, averaging
1.1 km (0.7 mi) in width, and 1,416 ha
(3,500 ac) in surface area.
The CPSD consist of a series of high,
mostly barren, dry dune ridges
separated by lower, moister, and more
vegetated interdunal swales (low places
between sand dune crests) (Romey and
Knisley 2002, p. 170). Wind action,
primarily blowing from south to north,
created and continues to shape the
CPSD, utilizing sand from nearby
eroding Navajo sandstone (Doelling et
al. 1989, p. 3). Wind velocity decreases
as it moves across the sand dunes (from
south to north), resulting in a dynamic
and less vegetated south CPSD area that
transitions to a less dynamic, more
heavily vegetated, higher elevation
northern CPSD area (Ford et al. 2010,
pp. 387–392).
PO 00000
Frm 00004
Fmt 4701
Sfmt 4702
The CPSD are in a semiarid climatic
zone (Ford et al. 2010, p. 381). The
nearest weather station, in Kanab, has a
mean annual temperature of 12.4
°Celsius (°C) (54.4 °Fahrenheit (°F)) and
mean annual precipitation of 33.8
centimeters (cm) (13.3 in) (Ford et al.
2010, p. 381). The northern 607 ha
(1,500 ac) of CPSD is Federal land
managed by the BLM. The southern 809
ha (2,000 ac) of the CPSD is within
Utah’s CPSD State Park.
Adult CPSD tiger beetles use most of
the dune areas from the swales to the
upper dune slopes. Larval CPSD tiger
beetles are more restricted to vegetated
swale areas (Knisley and Hill 2001, p.
386), where the vegetation supports the
larval prey base of flies, ants, and other
prey (Conservation Team 2009, p. 14).
Larval CPSD tiger beetle habitat is
typically dominated by the leguminous
plants Sophora stenophylla (silvery
sophora) and Psoralidium lanceolatum
(dune scurfpea), and several grasses,
including Sporobolus cryptandrus (sand
dropseed) and Achnatherum
hymenoides (Indian ricegrass). Larvae
also are closely associated with a
federally threatened plant species,
Asclepius welshii (Welsh’s milkvetch)
(Knisley and Hill 2001, p. 385) for
which the entire CPSD area is
designated critical habitat (52 FR 41435,
October 28, 1987).
Rainfall and associated soil moisture
is a critical factor for CPSD tiger beetles
(Knisley and Juliano 1988, entire) and is
likely the most important natural
environmental factor affecting
population dynamics of the species.
Rainfall and the associated increase in
soil moisture have a positive effect on
CPSD tiger beetle oviposition (egg
depositing) and survivorship (Knisley
and Hill 2001, p. 391). The areas in the
dune field with the highest level of soil
moisture and where soil moisture is
closer to the surface contain the highest
densities of CPSD tiger beetle larvae
(Knisley and Gowan 2011, p. 22),
indicating that both proximity to
moisture and overall soil moisture are
important to the CPSD tiger beetle’s life
cycle. Experimental supplemental
watering has resulted in significantly
more adults and larvae, more
oviposition events, increased larval
survival, and faster larval development
compared to unwatered control plots
(Knisley and Gowan 2011, pp. 18–22).
Population Distribution
The CPSD tiger beetle (Cincindela
albissima) occurs sporadically
throughout the CPSD geologic feature,
but only consistently exists in two
populations—central and northern—
which are separated by 4.8 km (3 mi)
E:\FR\FM\02OCP3.SGM

(Figure 1; Knisley 2012, pers. comm.).
The two populations occupy a total area
approximately 202 ha (500 ac) in size
(Morgan et al. 2000, p. 1109).
The central population is the largest
and is self-sustaining, but at relatively
low numbers (see Population Size and
Dynamics, below). The northern
population is not considered selfsustaining and comprises only a small
number of adults and larvae (Knisley
2001, p. 9). The northern population
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
likely persists because of adults
dispersing from the central population
(Knisley and Gowan 2011, p. 9).
Low densities of adult CPSD tiger
beetles also occur in the dune area
between the central and northern
populations (Figure 1; Hill and Knisley
1993, p. 9; Knisley 2012, pers. comm.),
and suitable swale habitat likely exists
in this area. This area has not been
extensively surveyed in the past 20
years, and observations of the species in
PO 00000
Frm 00005
Fmt 4701

60211
this area are from opportunistic and
inconsistent surveys. Because the
northern population likely is dependent
upon adults dispersing from the central
population (Knisley and Gowan 2011, p.
9), the 4.8-km (3-mi) long area of dune
between the two populations is likely an
important dispersal corridor for the
species (see Adult Dispersal below).

As previously mentioned (see

interagency CCA established
Conservation Areas A and B to protect
the CPSD tiger beetles from ORV use
(see Factor A, The Present or

Conservation Areas generally overlap
the central and northern populations of
CPSD tiger beetles (see Figure 1).
However, the central population does
not occupy the entirety of Conservation
Area A, and also extends outside of it.

information for the northern population,
so for purposes of this rule, we will
assume that the northern population,
during most years, occupies some swale
habitat in an area that overlaps
Conservation Area B entirely.
Conservation Area A is 84 ha (207 ac)
in size, and Conservation Area B is 150

ha (370 ac) in size (Knisley and Gowan
2011, pp. 7, 9).
We do not have comprehensive
analysis or occupancy modeling that
predicts the habitat preferences of the
CPSD tiger beetle. However, a
preliminary habitat assessment
indicated that the beetle exists where
there is abundant prey and larvae, large
swale areas capable of supporting the
appropriate vegetation, swale sediment
characteristics appropriate for
vegetation and larval burrows, dune
migration characteristics that permit
vegetation to develop and persist within
dune swales, proper sediment supply,
and a proper wind regime (Fenster et al.
2012, pp. 2–4). The presence of CPSD
tiger beetles in the northern and eastern
portions of Conservation Area A, to the
east and outside of Conservation Area A
(despite the lack of protection from ORV
traffic), and in limited swales in
Conservation Area B, indicate that many
or all of these habitat conditions occur
in these areas. See the Factor A section,
and other subsections in Background for
more information on CPSD tiger beetle
preferred habitat characteristics.
The same preliminary habitat
assessment indicated that CPSD tiger
beetles do not exist where there is a lack
of prey, small swale areas incapable of
supporting the appropriate vegetation,
swale sediment characteristics not
conducive for vegetation nor suitable for
larval burrows, dune migration
characteristics that do not permit
vegetation to develop and persist within
dune swales, low sediment supply, and
wind velocities that are too high or too
low to maintain proper dune form and
vegetation densities (Fenster et al. 2012,
pp. 4–5). The general absence of CPSD
tiger beetles in the south-central and
southeastern portions of Conservation
Area A and the general area south of
Conservation Area A, indicate that
many of these habitat conditions occur
in these areas. See the Factor A section,
and other subsections in Background for
more information on CPSD tiger beetle
preferred habitat characteristics.
Life History
Similar to other tiger beetles, the
CPSD tiger beetle goes through several
developmental stages. These include an
egg, three larval stages (known as
‘‘instars,’’ with each instar separated by
molting), pupa, and adult (Knisley and
Shultz 1997, p. 13). First instar larvae
appear in late spring after hatching from
eggs that were oviposited in sand the
previous late summer or fall (Hill and
Knisley 1997, p. 2). The first instar
larvae dig small vertical burrows from
the sand surface down 6 to 9 cm (2.4 to
3.5 in.) into the sand substrate
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
(Conservation Committee 2009, p. 14).
After several weeks of feeding at the
surface, the first instar larva plugs its
burrow opening, sheds its skin (molts),
and becomes a larger second instar larva
(Conservation Committee 1997, p. 2).
The second instar stage lasts several
months (again emerging from its burrow
and feeding at the surface for a brief
period) before developing into a third
instar, with most reaching this stage by
mid- to late summer (Conservation
Committee 1997, p. 2). Larvae continue
as second or third instars into fall, and
then hibernate in burrows during the
winter (Conservation Committee 1997,
p. 3). The third instar stage can take 9
months to over a year to reach full
development (Conservation Committee
1997, p. 3). After the third instar is fully
developed, the CPSD tiger beetle plugs
its burrow opening and transforms into
a pupa (Pearson and Vogler 2001, p. 34).
During the pupal period (stage between
third instar and adult emergence), the
beetle undergoes a metamorphosis
where many of the adult physical
structures develop (i.e., wings and flight
muscles) (Pearson and Vogler 2001, p.
34). Adults emerge soon after this
metamorphosis. The CPSD tiger beetle
completes its entire life cycle from egg
to adult reproduction to death within 2
or 3 years (Hill and Knisley 1997, p. 3).
Adult Behavior and Ecology
Adults are active on sunny days along
the dunes and swale edges. The majority
of recently metamorphosed adult CPSD
tiger beetles emerge from their burrows
in late March to early April, reach peak
abundance by May, begin declining in
June, and die by August (Knisley and
Hill 2001, p. 387). A small proportion of
a second adult cohort emerges in early
September and remains active into
October before digging overwintering
burrows (Knisley and Hill 2001, pp.
387–388).
Adult tiger beetles are active
predators, attacking and eating prey
with their large and powerful mandibles
(mouthparts). They can run or fly
rapidly over the sand surface to capture
or scavenge for prey arthropods. Adults
feed primarily on ants, flies, and other
small arthropods (Knisley and Hill
1993, p. 13).
CPSD tiger beetle behavior and
distribution, like other tiger beetles, is
largely determined by their
thermoregulation needs. Adult tiger
beetles dedicate up to 56 percent of
their daily activity towards behavior
that controls their internal body
temperature (Pearson and Vogler 2001,
p. 135). These behaviors include
basking (positioning the body to
maximize exposure to solar radiation);
PO 00000
Frm 00007
Fmt 4701
Sfmt 4702

seeking out wet, cool substrate or shade;
and burrowing (Pearson and Vogler
2001, p. 136). Tiger beetles with low
body temperatures are sluggish; tiger
beetles require a high body temperature
for maximal predatory activity (Pearson
and Vogler 2001, p. 131). Thus, the
numbers of adult CPSD tiger beetles
observed on rainy or cool, cloudy days
are very low (Knisley and Hill 2001, p.
388). Tiger beetles maintain body
temperatures near their lethal limits of
47 to 49 °C (116 to 120 °F) (Pearson and
Vogler 2001, p. 131), so heat refuge is
important (Shutlz and Hadley 1987, p.
363). During peak spring and fall
activity, when it is sunny, adult CPSD
tiger beetles are usually active early (9
a.m.–2 p.m.) and again in late afternoon
(4 p.m.–7 p.m.) (Knisley and Hill 1993,
pp. 13–14). They dig and reside in
burrows to avoid unfavorable weather
conditions such as hot mid-afternoons
or cool or rainy daytime conditions
(Knisley and Hill 1993, p. 14). Shade
provided by vegetative cover is
important for CPSD tiger beetle
thermoregulation during warm periods
(Knisley 2012, pers. comm.).
Adult Dispersal
Dispersal is the movement of
individuals from one habitat area to
another. The ability to disperse is often
important to tiger beetle species because
many species inhabit areas such as sand
dunes or riverbanks that are prone to
disturbance and physical change
(Pearson and Vogler 2001, pp. 130–142)
(see Factor E (Sand Dune Movement)
below). We do not have information on
the dispersal habits of the CPSD tiger
beetle, so we evaluated information for
surrogate species that occupy unstable
habitats similar to those of the CPSD
geologic formation. The Maricopa tiger
beetle, Cicindela oregona maricopa, is
an example of a species that persists in
an unstable environment because of
dispersal. The Maricopa tiger beetle
inhabits moist sandy habitat on the
banks of small streams and creeks
(Pearson and Vogler 2001, p. 141). Flash
flooding periodically scours away this
sandy habitat and most of the existing
population (Pearson and Vogler 2001, p.
141). These floods redistribute the
scoured sand elsewhere, and surviving
adult tiger beetles quickly disperse and
colonize the newly available habitat
(Pearson and Vogler 2001, p. 141).
Similarly for the CPSD tiger beetle, the
CPSD geologic formation is continually
changing as winds redistribute the
sands, both creating and destroying
swale habitat and dispersal habitat
within and between Conservation Areas
A and B (see Factor E Sand Dune
Movement below).

Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
Often, tiger beetle populations depend
upon dispersal among separated
populations for the survival of
individual populations and the species
(Knisley et al. 2005, p. 557). The
extirpation of at least one population of
the Northeastern Beach tiger beetle,
Cicindela dorsalis dorsalis, (federally
listed as a threatened species) is
partially attributed to the lack of nearby
populations and associated dispersal
habitats (Knisley et al. 2005, p. 557).
Similarly, in CPSD the northern
population of the CPSD tiger beetle
likely persists because of dispersal from
the central population, across the CPSD
(Knisley and Gowan 2011, p. 9). In like
fashion, the resilience of the central
population would be greatly increased if
the northern population became selfsustaining and could contribute to the
central population by dispersing across
the CPSD.

Larval Behavior and Ecology
Larval CPSD tiger beetles are ambush
predators that wait at their burrow
mouth to capture small arthropod prey
when it passes nearby. The daily period
of activity is highly variable and
influenced by temperature, moisture
levels, and season (Knisley and Hill
2001, p. 388; Knisley and Gowan 2008,
p. 20). Larvae can be active much of the
day during cool or cloudy spring and
fall days, except during high wind
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
periods (Conservation Committee 2009,
p. 14). Maximal activity occurs in early
mornings before the soil becomes dry
and warm from the sun and again in late
afternoon and evening after the soil has
cooled (Conservation Committee 2009,
p. 14).
Adult females determine the larval
microhabitat by their selection of an
oviposition site (Knisley and Gowan
2011, p. 6). Recently hatched larvae
construct burrows in the sand at the site
of oviposition and subsequently pass
through three larval stages before
pupating and then emerging to the adult
form (Conservation Committee 2009, p.
14). Most larvae occur within the swale
bottoms and up the lower slopes of the
dunes, particularly where the soil or
subsoil is moist most of the time (Hill
and Knisley 1996, p. 11; Knisley and
Gowan 2011, p. 22). The swale
vegetation supports the larval prey base
of ants, flies, and other prey
(Conservation Committee 2009, p. 14).
Larvae most often remain in the same
burrow throughout their development
and only rarely move outside of their
burrow to dig a new burrow in a more
favorable location (Knisley and Hill
1996, p. 11).
Population Size and Dynamics
Substantial year-to-year population
variation is typical of many desert
arthropods that are greatly affected by
PO 00000
Frm 00008
Fmt 4701
Sfmt 4725
climatic factors such as rainfall (Knisley
and Hill 2001, p. 391). Adult abundance
in any year is a result of many
interacting factors that affect
recruitment of the cohort oviposited 2 or
3 years previous (because of a 2- or 3year life cycle), and also the
survivorship of the developmental
stages of that year’s cohort (Knisley
2001, p. 10).
The central and northern populations
were monitored for the last 20 and 14
years (respectively) to yield a yearly
adult CPSD tiger beetle population size
estimate (monitoring did not take place
outside of these populations) (Figure 2).
The adult population size estimate is
based solely on data collected from the
central population from 1992 to 1997,
and after 1997 the adult population size
estimate is based on both populations.
Population numbers fluctuated greatly
over this time, ranging from a low of 558
in 2005 to a high of 2,944 in 2002
(Figure 2). The total adult population
size estimate in 2011 was 1,116 (Knisley
and Gowan 2011, p. 7). Population
monitoring results indicate a low, yet
stable to increasing population size
since 2003 that contrasts with highly
variable population estimates in
previous periods (Knisley and Gowan
2011, pp. 7–8; Figure 2); however, the
overall trend since 1992 suggests that
the population is in decline.

Population Viability Analysis
Population viability analysis (PVA) is
a way to predict the population
dynamics of a species under various
management alternatives (Brook et al.
2000, p. 385). PVAs generate future
predictions for a given species based
upon past and present population,
environmental data, and selected
management alternatives. Two PVAs are
available for the CPSD tiger beetle using
the same methods, one from 1998 using
adult population counts from 1992
through 1998, and the other from 2008
using adult counts from 1999 through
2008 (Knisley and Gowan 2009, pp. 17–
18).
Both PVAs only consider adult beetles
from the Conservation Area A
population because Conservation Area B
population numbers are extremely low
and the population is not considered
self-sustaining (Knisley 2001, p. 9). The
PVA authors caution that the CPSD tiger
beetle PVA should only be used in a
comparative way, to evaluate the
effectiveness of different management
options (Knisley 2012, pers. comm.).
They add that the PVA predictions may
not be quantitatively reliable for
predicting the absolute extinction
probability of the species (Knisley 2012,
pers. comm.). For these reasons, we do
not base our status determination for
this rulemaking on the PVA and instead
use the PVA to evaluate existing threats
and potential conservation measures.
The PVA models do not directly
account for current or future threats and
are entirely based on four demographic
variables:
1. Starting population size;
2. Population growth rate (increase in
population size year-to-year);
3. Stochasticity (variation in yearly
population growth rate); and
4. Carrying capacity (number of
beetles that the habitat can sustain).
The results of the two PVAs were
generally similar in that growth rate and
stochasticity tend to control extinction
probability. The most recent PVA
indicated a 32 percent chance of
extinction and an 87 percent chance
that the species would decline to 50
individuals within the next 100 years
(Knisley and Gowan 2009, p. 17). The
first PVA was based on only 7 years of
data and predicted extremely variable
extinction probabilities (2 percent to 96
percent in 100 years); however, the data
were based on very rough estimates of
population growth rates (Knisley and
Gowan 1999, pp. 5–6). Increases or
decreases in carrying capacity would
have only a modest effect on the risk of
extinction, whereas decreasing
stochasticity or increasing population

15:28 Oct 01, 2012
Jkt 229001
growth rate would greatly reduce the
chance of extinction (Knisley and
Gowan 2009, p. 18). The authors of the
PVA study recommended two
management actions to reduce the
extinction probability. Their first
recommendation was to expand both
Conservation Areas to include several
important swales that are believed to
have suitable habitat, but are being
impacted by heavy ORV use, thus
preventing successful colonization and
recruitment of CPSD tiger beetles
(Knisley and Gowan 2009, p. 23).
Expanding the size of both Conservation
Areas would likely increase the
population growth rate because the
protections would improve overall
habitat quality and lead to greater
reproductive success (e.g., Klok and de
Roos 1998, pp. 205–206). Their second
suggestion was to translocate beetles
and establish a self-sustaining
population in Conservation Area B
(Knisley and Gowan 2009, p. 23),
although this would likely require
improvements (e.g., vegetation removal
or watering during key development
stages) to the existing habitat (Knisley
2012, pers. comm.). The establishment
of a self-sustaining population in
Conservation Area B, or elsewhere in
the CPSD, would change the dynamics
of the PVA model by introducing the
possibility that a second self-sustaining
population could ‘‘rescue’’ or recolonize
the central population (and vice versa)
in the event that one of them were
extirpated.
Summary of Factors Affecting the
Species
Section 4 of the Act (16 U.S.C. 1533),
and its implementing regulations at 50
CFR part 424, set forth the procedures
for adding species to the Federal Lists
of Endangered and Threatened Wildlife
and Plants. Under section 4(a)(1) of the
Act, we may list a species based on any
of the following five factors: (A) The
present or threatened destruction,
modification, or curtailment of its
habitat or range; (B) overutilization for
commercial, recreational, scientific, or
educational purposes; (C) disease or
predation; (D) the inadequacy of
existing regulatory mechanisms; and (E)
other natural or manmade factors
affecting its continued existence. Listing
actions may be warranted based on any
of the above threat factors, singly or in
combination. Each of these factors is
discussed below.
Factor A. The Present or Threatened
Destruction, Modification, or
Curtailment of Its Habitat or Range
Loss of habitat is the leading cause of
species extinction (Pimm and Raven
PO 00000
Frm 00009
Fmt 4701
Sfmt 4702
60215
2000, p. 843). Insects are highly
vulnerable to extinction through habitat
loss (McKinney 1997, pp. 501–507).
ORV use significantly impacts the CPSD
tiger beetle’s habitat, range, and the
beetle itself by directly killing beetles,
damaging vegetation that supports prey
items, directly killing prey items, and
reducing soil moisture.
Nationwide, ORV use has drastically
reduced or extirpated several tiger
beetle populations. For example, ORV
use and pedestrian traffic extirpated the
Northeastern Beach tiger beetle,
Cicindela dorsalis dorsalis, in several
localities (Knisley 2011, p. 45).
Similarly, within several years of the
Assateague Island National Seashore
(Maryland, USA) opening for ORV use,
the White Beach tiger beetle, C. d.
media, was extirpated from all but those
areas where ORVs were restricted
(Knisley and Hill 1992, pp. 138–139).
Additionally, ORV use is responsible for
eliminating tiger beetle populations in
coastal southern California (Hairynecked tiger beetle, C. hirticollis
gravida), Oregon and Washington
(Siuslaw hairy-necked tiger beetle, C. h.
siuslawensis), and Idaho (St. Anthony
Dune tiger beetle, C. arenicola) (Knisley
2011, p. 45).
As previously described (see Previous
Federal Actions, Population
Distribution, and Figure 1), in 1997, the
Service, BLM, Utah State Parks and
Recreation, and Kane County developed
and signed a CCA and formed a
conservation committee to protect the
CPSD tiger beetle within an ORV-use
area (Conservation Committee 1997).
The CCA established Conservation
Areas A and B (see Figure 1 in
Population Distribution above) to
protect CPSD tiger beetle habitat from
ORV use: Conservation Area A—84 ha
(207 ac) are closed to ORV use within
the CPSD State Park; and Conservation
Area B—150 ha (370 ac) are closed to
ORV use on BLM land.
Because we do not have survey
information to determine the extent of
occupied swale habitat in the northern
population (see Population Distribution)
and because the entirety of the northern
population occurs within Conservation
Area B (protected from ORV use), the
below analysis is specific to the central
population and Conservation Area A.
Conservation Area A protects 48 percent
of the swale habitat occupied by the
CPSD tiger beetle in the central
population, as well as 73 to 88 percent
of CPSD tiger beetle adults and the vast
majority of larvae from ORV activities.
ORV use still occurs in 52 percent of
occupied CPSD tiger beetle swale
habitat in the central population (Figure

Available information shows the
effects of ORV use on current
population numbers. For example,
swales adjacent to but outside of

Conservation Area A are similar in all
apparent environmental conditions to
swales within Conservation Area A with
the exception of ORV impacts. However,

impacted occupied swales is
consistently lower than adjacent
protected occupied swales, potentially
because of ORV impacts (Figure 3).

For example, one swale with ORV use
had population counts of 60 or more
CPSD tiger beetles in most years
(Knisley and Gowan 2011, p. 11). Utah
State Park staff, at the recommendation
of the conservation committee,
protected this swale from ORV use in
2010 (Knisley and Gowan 2011, p. 11).
The year following removal of ORV use,
the tiger beetle density on this swale
more than doubled to 150 beetles,
which also is the highest number
recorded for the swale (Knisley and
Gowan 2011, p. 11). This action
provides an example of how the
conservation committee has used
adaptive management to benefit the
CPSD tiger beetle and demonstrates a
rapid population response to removed
ORV disturbance.
ORVs run over and thereby kill and
injure CPSD tiger beetles (Knisley and
Hill 1993, p. 14; Knisley and Gowan
2008, p. 23). The likelihood of being
injured or killed increases if adult CPSD
tiger beetle are run over on wet or
compact substrates (e.g., moist swales)
as compared to soft sands (e.g., dune
faces) (Knisley and Hill 2001, p. 390).
The likelihood of being hit by ORVs also
increases based on the level of ORV use.
For example, the numbers of adult
CPSD tiger beetles found injured or
killed by ORVs increases substantially
during periods of heavy use, such as
during the Memorial Day holiday (Table
1; Knisley and Hill 2001, p. 390). We
have no information quantifying the
direct injury or mortality that ORVs
cause to eggs or larval CPSD tiger beetle
because these stages are underground
and not easily monitored.

We do not have specific data
regarding the level of impact ORVs have
on CPSD tiger beetles in the unprotected
area between Conservation Areas A and
B. It is likely that many of the beetles
run over by ORVs in the dispersal
corridor will be injured or killed. Thus,
the ability of adults to disperse between
the central population and the northern
population is likely negatively impacted
by ORVs. The result of these ORV
impacts is that the habitat between the
central and northern populations does
not provide a sufficient dispersal
corridor for beetles to the northern
population. Current levels of dispersal
are likely not adequate for the northern
population to be self-sustaining (see
Population Viability Analysis). Thus,
BLM protection of only Conservation
Area B, and the absence of protection in
the dispersal corridor, results in the
continued threat of ORV use to the
CPSD tiger beetle.
Food limitation has a significant
impact on tiger beetle growth, survival,
and fecundity, especially for desert
species. Adult CPSD tiger beetles are, in
some years, extremely food limited and
exhibit reduced fecundity (Knisley and
Gowan 2008, p. 19). Food limitation is
at least partly caused by ORV use. ORVs
reduce CPSD tiger beetle prey density
and prey species diversity in CPSD
(Knisley and Gowan 2006, p. 19). Ants,
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
a primary prey item, occur in much
lower densities in areas frequented by
ORVs than in areas with no ORV traffic
(Knisley and Gowan 2008, p. 23). In
addition, low ORV use areas in CPSD
have a higher diversity of prey species
and higher numbers of prey items than
high ORV use areas (Knisley and Hill
2001, p. 389).
Prey availability significantly affects
the number of larvae produced by adult
tiger beetles (Pearson and Knisley 1995,
p. 165) and the survival of larval tiger
beetles (Knisley and Juliano 1988, p.
1990). Low prey densities can result in
prolonged development and decreased
survivorship in larval tiger beetles and
reduced size in adults, which lowers
fecundity in females (Pearson and
Knisley 1985, p. 165; Knisley and
Juliano 1988, p. 1990). Also, low prey
densities require larval and adult tiger
beetles to spend more time searching for
food. For larval tiger beetles, this means
more time near burrow entrances
searching for prey, resulting in
increased susceptibility to parasitism
and predators (Pearson and Knisley
1985, p. 166). Similarly, adults that
spend more time out of their burrows
searching for food have an increased
susceptibility to predation.
ORV use degrades larval habitat by
reducing soil moisture. ORV use can
reduce soil moisture by churning up
PO 00000
Frm 00011
Fmt 4701
Sfmt 4702
soils and exposing the moisture that is
locked between soil particles (beneath
the surface) to greater evaporative
pressure (Shultz 1988, p. 28; Knisley
and Gowan 2008, p. 10). It also reduces
soil moisture by increasing soil
compaction (Adams et al. 1982, p. 167).
Compaction reduces water infiltration
and reduces moisture retention in soils
(Belnap 1995, p. 39).
As we discussed earlier (see Habitat),
soil moisture is essential to the CPSD
tiger beetle’s life history. Extreme drying
or desiccation kills tiger beetles (Knisley
and Juliano 1998, p. 1990). In a dry
environment, such as the CPSD geologic
feature, organisms are constantly
struggling to acquire and maintain
enough water to survive. Water is
limiting to tiger beetles in CPSD, and
this is evidenced by the fact that
experimental water supplementation
increased larval CPSD tiger beetle
survival by 10 percent (Knisley and
Gowan 2008 p. 20). CPSD areas
protected from ORV use have
significantly higher soil moistures and
higher numbers of CPSD tiger beetles
than adjacent ORV use areas (Knisley
and Gowan 2008, pp. 10–11).
Overall, ORV use reduces available
habitat and the CPSD tiger beetle
population size. This results in a
population that is at risk of
endangerment in the face of minor

wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
Summary of Factor A
ORV use is a threat to the CPSD tiger
beetle through direct mortality and
injury, and by reducing prey base and
soil moisture. ORV use substantially
reduces habitat qualities essential to the
CPSD tiger beetle’s life cycle (e.g., soil
moisture and prey availability) (Knisley
and Hill 2001, p. 389; Knisley and
Gowan 2008, pp. 10–11). Reduction in
habitat quality reduces reproductive
success and the tiger beetle population
growth rate (e.g., Klok and de Roos
1998, pp. 205–206). We acknowledge
the very important protections of
Conservation Areas A and B from ORV
use. However, despite these
conservation efforts, 52 percent of
occupied swale habitat, which occurs
outside of the Conservation Areas, is
currently unprotected (Figure 3, Knisley
and Gowan 2009, p. 8) and the
degradation of habitat (both occupied
and potential) by ORV use reduces the
ability of the population to expand or
disperse in areas outside of the
Conservation Areas and thereby reduces
the population’s carrying capacity. As
the PVA demonstrates (see Population
Viability Analysis above), reductions in
growth rate and carrying capacity (albeit
a moderate effect on PVA compared to
growth rate) increase the probability of
extinction for this species. Based on
current ORV use and CPSD tiger beetle
population levels, there is a 32 percent
probability that the species will go
extinct in the next 100 years, and the
PVA does not consider future threats
(see Population Viability Analysis
above). As we will discuss in Factor E,
environmental effects from climate
change and drought conditions will
likely exacerbate reductions in soil
moisture associated with ORV use, thus
increasing the extinction risk even
further. The best scientific and
commercial information available
indicates that the destruction,
modification, or curtailment of the
CPSD tiger beetle’s habitat or range due
to ORV use is a threat to the species
now and in the future.
Factor B. Overutilization for
Commercial, Recreational, Scientific, or
Educational Purposes
Tiger beetles are one of the most
sought-after groups of insects by
amateur collectors because of the
unique metallic colors and patterns
present in the various species and
subspecies, as well as their fascinating
habits (Pearson et al. 2006, pp. 3–5).
Interest in the genus Cicindela is
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
reflected in the scientific journal
entitled ‘‘Cicindela,’’ which is
published quarterly (since 1969) and is
exclusively devoted to the genus. In
certain circumstances, collection of
these insects can add valuable
information regarding biogeography,
taxonomy, and life history of the
species. However, some collection is
purely recreational and adds little to no
value to the scientific understanding or
conservation of tiger beetles.
Collection of adult CPSD tiger beetles,
before they mate and lay their eggs, may
result in reduced population size of
subsequent generations. The magnitude
of recreational collection cannot be
accurately determined for the CPSD
tiger beetle, but it is likely that some
number of adults were taken in the past.
However, CPSD State Park and BLM
personnel now enforce restrictions on
recreational collecting of CPSD tiger
beetles, and consequently, collection
levels are low (Conservation Committee
2009, p. 17). Although scientific
collection is not restricted by any formal
permitting process, only one researcher
has collected CPSD tiger beetles in
approximately the last 14 years. Over
this time period, approximately 70
adults were collected (Knisley 2012,
pers. comm.). The adults were collected
in late May after they had mated and
oviposited eggs (Knisley 2012, pers.
comm.).
Summary of Factor B
CPSD tiger beetles are not overutilized
for commercial, recreational, scientific,
or educational purposes. A limited
number of CPSD tiger beetles are likely
collected from wild populations for
recreational purposes; however, CPSD
State Park and BLM personnel enforce
restrictions on recreational collecting.
Collection of CPSD tiger beetles for
scientific investigation purposes occurs
on occasion, but the level of collection
is very small. The best scientific and
commercial information available
indicates that overutilization for
commercial, recreational, scientific, or
educational purposes is not a threat to
the CPSD tiger beetle now nor will be
in the future.
Factor C. Disease or Predation
We know of no diseases that are a
threat to the CPSD tiger beetle. Natural
mortality through predation and
parasitism accounts for some individual
loss of adult and larval CPSD tiger
beetles (Knisley and Hill 1994, p. 16).
Known predators of adult tiger beetles
include birds, shrews (Soricidae),
raccoons (Procyon lotor), lizards
(Lacertilia), toads (Bufonidae), ants
(Formicidae), robber flies (Asilidae), and
PO 00000
Frm 00012
Fmt 4701
Sfmt 4702
dragonflies (Anisoptera) (Knisley and
Shultz 1997, pp. 57–59). Despite a
documented level of natural predation
of CPSD tiger beetles, effects to the
species are low and not likely to limit
the CPSD tiger beetle population
(Conservation Committee 2009, p. 17).
Known tiger beetle parasites include
ant-like wasps of the family Typhiidae,
especially the genera Mathoca, Karlissa,
and Pterombrus, and flies of the genus
Anthrax (Knisley and Shultz 1997, pp.
53–57). Parasites predominantly target
larval tiger beetles (Pearson and Vogler
2001, pp. 170–171). There are two
known natural parasites of larval CPSD
tiger beetles. Bee flies (Bombyliidae) are
known to flick their eggs into beetle
burrows (Knisley and Hill 1995, p. 14).
When these eggs hatch, the larval
parasite feeds on beetle bodily fluids,
often resulting in death of the tiger
beetle larvae. Wasps of the genus
Methoca also can parasitize CPSD tiger
beetle larvae (Knisley and Hill 1995, p.
14). These wasps deposit their larvae in
the burrows of larval tiger beetles. The
wasp larvae then consume the tiger
beetle larvae. Despite documented
parasitism to larval CPSD tiger beetle,
effects to the species are low and not
likely to limit the CPSD tiger beetle
population (Conservation Committee
1997, p. 7).
Summary of Factor C
We have found no information that
indicates that disease is a threat to the
CPSD tiger beetle. There is some
information documenting mortality of
CPSD tiger beetles by natural predators
and parasites; however, not to a level
that significantly affects the species.
Thus, we have no information that
disease, parasites, or predation is a
threat to the species now or is likely to
become so in the future.
Factor D. The Inadequacy of Existing
Regulatory Mechanisms
The Act requires us to examine the
inadequacy of existing regulatory
mechanisms with respect to extant
threats that place CPSD tiger beetle in
danger of becoming either an
endangered or threatened species.
Regulatory mechanisms affecting the
species fall into three general categories:
(1) Land management; (2) State
mechanisms; and (3) Federal
mechanisms.
Land Management
The CPSD geologic feature is
approximately 1,416 ha (3,500 ac). The
southern 809 ha (2,000 ac) of the CPSD
is within the CPSD State Park and is
categorized as public land with a
recreational emphasis (Conservation
E:\FR\FM\02OCP3.SGM
02OCP3
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
Committee 2009, p. 17). The State Park’s
mission, as described in the most recent
general management plan (Franklin et
al. 2005, p. 3), is ‘‘to provide visitors
[* * *] recreation experiences while
preserving and interpreting the park’s
natural, scenic, and recreation
resources.’’ The northern 607 ha (1,500
ac) is Federal land managed by the
BLM’s Kanab Field Office (BLM 2000, p.
14). The northern area is partly within
the Moquith Mountain Wilderness
Study Area (WSA). Public education for
both areas includes signage, brochures,
and interpretive programs.
As stated previously (see Factor A),
the UDNR (which oversees the Utah
Division of State Parks and Recreation),
the BLM, the Service, and Kane County
developed and signed a CCA in 1997
(Conservation Committee 1997), and
renewed the agreement in 2009
(Conservation Committee 2009, entire).
The CCA recommends conservation
objectives and actions designed to
protect and conserve the CPSD tiger
beetle. Although the CCA is not a
regulatory mechanism in and of itself,
the agencies have implemented
specified conservation actions,
including the protection of Conservation
Areas A and B that are regulatory
mechanisms. These mechanisms are
Utah Administrative Code R651–633
and the BLM’s Kanab RMP. The degree
to which the CCA has ameliorated the
threats is discussed below.
Protection for the tiger beetle in
Conservation Area A is enforced
according to the CPSD State Park’s
special closure (Conservation
Committee 1997, p. 13) and Utah’s
Administrative Code (R 651–633).
Conservation Area A protects some of
the central population of CPSD tiger
beetle. Of the 809-ha (2,000-ac) State
Park, 84 ha (207 ac) (10 percent) are
closed to ORV use to provide protection
for CPSD tiger beetle habitat.
Conservation Area A prohibits the use
of ORVs in 48 percent of the species’
known occupied swale habitat in the
central population, thereby protecting
73 to 88 percent of CPSD tiger beetle
adults and the vast majority of larvae
(Figure 3, adapted from Knisley and
Gowan 2009, p. 8).
Conservation Area B provides
protection to all of the northern
population’s habitat as we have defined
its boundary (see Figure 1), realizing
that we do not have good survey
information in this area. In this area,
150 ha (370 ac) is closed to ORV use to
protect a small population of CPSD tiger
beetle. Approximately 445 ha (1,100 ac)
is available for ORV use outside of the
Conservation Area B on BLM lands, but
with the stipulation that ORVs stay on
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
open dunes and maintain a 3-m (10-ft)
buffer around vegetation. Enforcement
is minimal and primarily relies on
voluntary compliance (Conservation
Committee 1997, p. 13). We have no
record of enforcement effort or success
of the closures at either Conservation
Area A or B.
Despite the designation and
management of the Conservation Areas,
at least 52 percent of known occupied
swale habitat in the central population
adjacent to Conservation Area A is open
to ORV use, and an unknown amount of
habitat could be affected in the northern
population (Knisley and Gowan 2009, p.
8). As previously described, unprotected
but occupied swales have lower CPSD
tiger beetle densities than nearby
protected swales that are occupied (see
Figure 3).
In addition to the lack of any
protection for about 52 percent of
occupied swale habitat that is outside of
Conservation Area A, there is no
protection from ORV use for the CPSD
tiger beetle in the dispersal corridor
between Conservation Areas A and B.
As explained above (see Adult
Dispersal), this area is important for
dispersal of tiger beetles from
Conservation Area A to Conservation
Area B and likely is necessary to
maintain the northern CPSD tiger beetle
population in Conservation Area B.
We acknowledge the very important
protections of Conservation Areas A and
B from ORV use. However, outside of
the two Conservation Areas, at least 52
percent of occupied swale habitat is
currently unprotected and the
degradation of habitat (both occupied
and potential) by ORV use reduces the
ability of the CPSD tiger beetle
population to expand in areas outside of
protected Conservation Areas and
reduces the population’s carrying
capacity. The dispersal habitat between
Conservation Areas A and B is managed
by the Utah Division of State Parks and
Recreation and the BLM, and used
largely for OHV recreation; no
regulatory mechanisms protect the
CPSD tiger beetle in this area.
At current levels of regulatory
protection, CPSD tiger beetle habitat is
small and isolated in the two
Conservation Areas, and the population
size is extremely small, making the
species more susceptible to other threats
such as climate change and drought,
demographic and environmental
stochasticity, and catastrophic events
(see Factor E. Climate Change and
Drought and Small Population Effects).
As explained previously (see the
Background: Population Distribution),
the central population of CPSD tiger
beetle only occupies a portion of
PO 00000
Frm 00013
Fmt 4701
Sfmt 4702
60219
Conservation Area A, and based on
population and habitat sampling results
to date, we believe it is not likely that
the species will expand to other areas in
Conservation Area A due to insufficient
habitat conditions. Instead we believe
that Conservation Area A should be
expanded (using regulatory
mechanisms) to protect occupied habitat
that is already being used by the species
but currently is at levels that are
artificially low due to the effects of
ORVs (see Population Viability Analysis
and Factor A).
In addition, the population at
Conservation Area B should be managed
such that it becomes self-sustaining (see
Population Viability Analysis and
Factor A). However, at this point in time
it is unclear from a regulatory
perspective what will be necessary to
achieve this. It is possible that by
expanding Conservation Area A, the
central population will increase such
that it will be sufficient to provide
adequate numbers of dispersers to
bolster the population at Conservation
Area B, thus making it self-sustaining.
There may need to be additional
regulatory measures put in place to
protect the dispersal corridor between
Conservation Areas A and B to allow for
a safe and sufficient level of CPSD tiger
beetle dispersal between the two areas.
State Mechanisms
Utah’s Administrative Code (R 651–
633) prohibits motorized vehicle use in
designated nonmotorized sand dune
areas of CPSD State Park. Conservation
Area A is a designated nonmotorized
sand dune area, and thus the State Code
protects tiger beetle habitat in this area.
CPSD State Park’s dual purpose mission
statement of providing recreational
experiences while preserving natural
resources (Franklin et al. 2005, p. 3) has
assisted with the conservation of CPSD
tiger beetle to some extent because the
State Park has closed areas
(Conservation Area A) to ORV use to
protect CPSD tiger beetle. However, the
State Park also promotes recreational
use; in this case, extensive ORV use is
still permitted across the majority of the
State Park, which is ultimately
detrimental to maintaining a selfsustaining population of CPSD tiger
beetles in the central area in the future
(see Factor A for an analysis of ORV
impacts).
Federal Mechanisms
As mentioned previously,
Conservation Area B and the northern
population are on BLM-administered
land. The Federal Land Policy and
Management Act of 1976 (FLPMA) (43
U.S.C. 1701 et seq.) is the primary
E:\FR\FM\02OCP3.SGM
02OCP3
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
60220
Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
Federal law governing most land uses
on BLM-administered lands. Section
102(a)(8) of FLPMA specifically
recognizes wildlife and fish resources as
being among the uses for which these
lands are to be managed. Regulations
pursuant to FLPMA and the Mineral
Leasing Act (30 U.S.C. 181 et seq.) that
address wildlife habitat protection on
BLM-administered land include 43 CFR
3162.3–1 and 43 CFR 3162.5–1; 43 CFR
4120 et seq.; and 43 CFR 4180 et seq.
The BLM manages the CPSD tiger
beetle as a ‘‘sensitive species,’’ and as
stated above, BLM manages a 150-ha
(370-ac) Conservation Area for the
species. The management guidance
afforded sensitive species under BLM
Manual 6840—Special Status Species
Management (BLM 2008, entire) states
that ‘‘Bureau sensitive species will be
managed consistent with species and
habitat management objectives in land
use and implementation plans to
promote their conservation and to
minimize the likelihood and need for
listing under the ESA’’ (BLM 2008, p.
05V). The BLM Manual 6840 further
requires that Resource Management
Plans (RMPs) should address sensitive
species, and that implementation
‘‘should consider all site-specific
methods and procedures needed to
bring species and their habitats to the
condition under which management
under the Bureau sensitive species
policies would no longer be necessary’’
(BLM 2008, p. 2A1). As a designated
sensitive species under BLM Manual
6840, CPSD tiger beetle conservation
must be addressed in the development
and implementation of RMPs on BLM
lands.
The RMPs are the basis for all actions
and authorizations involving BLMadministered lands and resources. They
establish allowable resource uses,
resource condition goals and objectives
to be attained, program constraints and
general management practices needed to
attain the goals and objectives, general
implementation sequences, and
intervals and standards for monitoring
and evaluating the plan to determine its
effectiveness and the need for
amendment or revision (43 CFR 1601 et
seq.).
The RMPs provide a framework and
programmatic guidance for activity
plans, which are site-specific plans
written to implement decisions made in
an RMP. Activity plan decisions
normally require additional planning
and National Environmental Policy Act
(NEPA) analysis (see below). If an RMP
contains specific direction regarding
sensitive species habitat, conservation,
or management, it represents an
enforceable regulatory mechanism to
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
ensure that the species and its habitats
are considered during permitting and
other decision-making regarding BLM
lands.
The 2008 Kanab RMP establishes
guidance and objectives for the
management of the northern portion of
CPSD (BLM 2008, entire). In the RMP,
the BLM commits to ‘‘implement
conservation actions identified in the
Conservation Agreement and Strategy
for the Coral Pink Sand Dunes tiger
beetle, including maintaining the
established 370-acre conservation area’’
(BLM 2008, p. 32). In addition to
maintaining Conservation Area B, the
BLM has funded and continues to fund
CPSD tiger beetle monitoring and
research activities. While these BLMimplemented conservation actions (as
outlined in the RMP) have benefitted
the CPSD tiger beetle, remaining threats
(such as climate change and drought,
demographic and environmental
stochasticity, and catastrophic events
(see Factor E. Climate Change and
Drought and Small Population Effects)
and ORVs (see Population Viability
Analysis and Factor A)) continue to
negatively affect the species.
BLM manual 6840 establishes
management policy and direction for
BLM’s involvement in the CCA and its
membership on the Conservation
Committee (Conservation Committee
2009, p. 7). Conservation Area B was
established on BLM lands as part of the
CCA and was a result of adult and larval
CPSD tiger beetle discovered in this area
during a 1996 monitoring effort (Knisley
and Hill 1997, p. 11; Conservation
Committee 1997, entire). BLM land
management practices are intended to
avoid negative effects whenever
possible, while also providing for
multiple-use mandates; therefore,
maintaining or enhancing CPSD tiger
beetle habitat is considered in
conjunction with other agency
priorities.
The BLM protects the entirety of the
northern CPSD tiger beetle population
in Conservation Area B; however, this
population is not self-sustaining (see
Population Distribution). As we discuss
previously, the northern population
likely persists because of dispersal from
the central population (see Adult
Dispersal). However, current levels of
dispersal are likely not adequate for the
northern population to be selfsustaining (see Population Viability
Analysis). The habitat between the
central and northern populations
(between Conservation Areas A and B)
is managed by the BLM and Utah
Division of State Parks and Recreation
and is not protected from ORV use (see
Figure 2). The ORV use in this
PO 00000
Frm 00014
Fmt 4701
Sfmt 4702
unprotected zone results in habitat
degradation and loss of beetles that are
injured or killed by ORVs. The result of
these ORV impacts is that the habitat
between the central and northern
populations does not provide a
sufficient dispersal corridor for beetles
to the northern population (see Factor A
for effects of ORVs in CPSD tiger beetle
habitat). Thus, BLM protection of only
Conservation Area B, and the absence of
protection in the dispersal corridor,
results in the continued threat of ORV
use to the CPSD tiger beetle (see Factor
A).
On December 15, 2009, the
Environmental Protection Agency (EPA)
published in the Federal Register (74
FR 66496) a rule titled, ‘‘Endangerment
and Cause or Contribute Findings for
Greenhouse Gases Under Section 202(a)
of the Clean Air Act.’’ In this rule, the
EPA Administrator found that the
current and projected concentrations of
the six long-lived and directly emitted
greenhouse gases (GHGs)—carbon
dioxide, methane, nitrous oxide,
hydrofluorocarbons, perfluorocarbons,
and sulfur hexafluoride—in the
atmosphere threaten the public health
and welfare of current and future
generations; and that the combined
emissions of these GHGs from new
motor vehicles and new motor vehicle
engines contribute to the GHG pollution
that threatens public health and welfare
(74 FR 66496). In effect, the EPA has
concluded that the GHGs linked to
climate change are pollutants, whose
emissions can now be subject to the
Clean Air Act (42 U.S.C. 7401 et seq.)
(see 74 FR 66496). However, specific
regulations to limit GHG emissions were
only proposed in 2010 and, therefore,
cannot be considered an existing
regulatory mechanism. At present, we
have no basis to conclude that
implementation of the Clean Air Act in
the future (40 years, based on global
climate projections) will substantially
reduce the current rate of global climate
change through regulation of GHG
emissions.
A Federal statute that may provide
protection to CPSD tiger beetle and its
habitat is the NEPA. As explained
previously, Federal land management
agencies, such as the BLM, have
legislation that specifies how their lands
are managed for sensitive species. The
NEPA provides authority for the Service
to assume a cooperating agency role for
Federal projects undergoing evaluation
for significant impacts to the human
environment. This includes
participating in updates to RMPs. As a
cooperating agency, we have the
opportunity to provide
recommendations to the action agency
E:\FR\FM\02OCP3.SGM
02OCP3
Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
to avoid impacts or enhance
conservation for CPSD tiger beetle and
its habitat where it occurs on Federal
land. For projects where we are not a
cooperating agency, we often review
proposed actions and provide
recommendations to minimize and
mitigate impacts to fish and wildlife
resources. However, acceptance of our
NEPA recommendations is not required
and is at the discretion of the action
agency.
Summary of Factor D
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
State and federally managed lands in
Conservation Areas A and B provide
some protection to the CPSD tiger
beetle. The northern portion of CPSD is
Federal land managed by the BLM and
the southern portion of the CPSD is
within the CPSD State Park. These land
management agencies provide
protection to the CPSD tiger beetle
through the establishment and
regulation of the ORV restricted
Conservation Areas A and B. Utah’s
Administrative Code (R 651–633)
prohibits motorized vehicle use in
designated nonmotorized sand dune
areas of CPSD State Park (Conservation
Area A) and the BLM protects
Conservation Area B. However, as
discussed under Factor A, ORV use is
the primary threat to the beetle, and this
threat is not being addressed with any
existing regulatory mechanisms in the
area between Conservation Areas A and
B (managed by BLM and Utah Division
of State Parks and Recreation) and to the
east of Conservation Area A (managed
by CPSD State Park). As a result, the
habitat quality is negatively affected,
and tiger beetles that disperse outside of
the two Conservation Areas can be
injured or killed by ORVs.
The Clean Air Act gives the EPA
authority to limit GHGs linked to
climate change; however, our analysis
concludes that current regulation of
these gases is not adequate to reduce the
current rate of global climate change.
As evidenced by the discussion
above, the species is not adequately
protected by existing regulatory
mechanisms.
Factor E. Other Natural or Manmade
Factors Affecting Its Continued
Existence
Natural and manmade factors
affecting the CPSD tiger beetle include:
(1) Sand dune movement; (2) Climate
change and drought; (3) Small
population effects; and (4) Cumulative
effects of all threats that may impact the
species.
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
Sand Dune Movement
Movement of the swales due to sand
dune movement naturally occurs in this
system as wind action continues to
shape the dunes. Major dune ridgelines
moved close to 22 m (72 ft) (Knisley and
Gowan 2005, p. 4) between 2001 and
2002, and most ridgelines moved over
45 m (150 ft) between 2002 and 2010
(Knisley and Gowan 2011, p. 25). Dune
movement can result in a change in
suitable habitat conditions (Knisley and
Gowan 2008, pp. 21–22). For example,
dune movement simultaneously buries
and uncovers trees in CPSD (Gregory
1950, p. 188). Similarly, we know that
dune movement is burying some
previously occupied swale habitat
(Knisley and Gowan 2008, pp. 21–22). It
is likely that dune movement is
uncovering potential habitat as well;
however, comprehensive surveys to
determine this have not been conducted
(Knisley 2012, pers. comm.). Wind
action created and continues to shape
the current CPSD (Ford et al. 2010, p.
387), and we have no evidence to
suggest that the rate of dune movement
is increasing. Because CPSD tiger beetle
presumably evolved in this
environment, it is likely that the species
is adapted to the continual movement of
dunes. We have no evidence
demonstrating that dune movement is a
threat to the species now or is likely to
become so in the future; however,
additional study of dune movement is
recommended.
Climate Change and Drought
Our analyses under the Act include
consideration of environmental changes
resulting from ongoing and projected
changes in climate. The terms ‘‘climate’’
and ‘‘climate change’’ are defined by the
Intergovernmental Panel on Climate
Change (IPCC). ‘‘Climate’’ refers to the
mean and variability of different types
of weather conditions over time, with 30
years being a typical period for such
measurements, although shorter or
longer periods also may be used (IPCC
2007a, p. 78). The term ‘‘climate
change’’ thus refers to a change in the
mean or variability of one or more
measures of climate (e.g., temperature or
precipitation) that persists for an
extended period, typically decades or
longer, whether the change is due to
natural variability, human activity, or
both (IPCC 2007a, p. 78).
Scientific measurements spanning
several decades demonstrate that
changes in climate are occurring, and
that the rate of change has been faster
since the 1950s. Based on extensive
analyses of global average surface air
temperature, the most widely used
PO 00000
Frm 00015
Fmt 4701
Sfmt 4702
60221
measure of change, the IPCC concluded
that warming of the global climate
system over the past several decades is
‘‘unequivocal’’ (IPCC 2007a, p. 2). In
other words, the IPCC concluded that
there is no question that the world’s
climate system is warming.
Examples of other changes include
substantial increases in precipitation in
some regions of the world and decreases
in other regions (for these and
additional examples, see IPCC 2007a, p.
30; Solomon et al. 2007, pp. 35–54, 82–
85). Various environmental changes
(e.g., shifts in the ranges of plant and
animal species, increasing ground
instability in permafrost regions,
conditions more favorable to the spread
of invasive species and of some
diseases, changes in amount and timing
of water availability) are occurring in
association with changes in climate (see
IPCC 2007a, pp. 2–4, 30–33; and Global
Climate Change Impacts in the United
States 2009, pp. 27, 79–88).
Results of scientific analyses
presented by the IPCC show that most
of the observed increase in global
average temperature since the mid-20th
century cannot be explained by natural
variability in climate and is ‘‘very
likely’’ (defined by the IPCC as 90
percent or higher probability) due to the
observed increase in GHG
concentrations in the atmosphere as a
result of human activities, particularly
carbon dioxide emissions from fossil
fuel use (IPCC 2007a, pp. 5–6 and
figures SPM.3 and SPM.4; Solomon et
al. 2007, pp. 21–35). Further
confirmation of the role of GHGs comes
from analyses by Huber and Knutti
(2011, p. 4), who concluded it is
extremely likely that approximately 75
percent of global warming since 1950
has been caused by human activities.
Scientists use a variety of climate
models, which include consideration of
natural processes and variability, as
well as various scenarios of potential
levels and timing of GHG emissions, to
evaluate the causes of changes already
observed and to project future changes
in temperature and other climate
conditions (e.g., Meehl et al. 2007,
entire; Ganguly et al. 2009, pp. 11555,
15558; Prinn et al. 2011, pp. 527, 529).
All combinations of models and
emissions scenarios yield very similar
projections of average global warming
until about 2030. Although projections
of the magnitude and rate of warming
differ after about 2030, the overall
trajectory of all the projections is one of
increased global warming through the
end of this century, even for projections
based on scenarios that assume that
GHG emissions will stabilize or decline.
Thus, there is strong scientific support

Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
for projections that warming will
continue through the 21st century, and
that the magnitude and rate of change
will be influenced substantially by the
extent of GHG emissions (IPCC 2007a,
pp. 44–45; Meehl et al. 2007, pp. 760–
764; Ganguly et al. 2009, pp. 15555–
15558; Prinn et al. 2011, pp. 527, 529).
In addition to basing their projections
on scientific analyses, the IPCC reports
projections using a framework for
treatment of uncertainties (e.g., they
define ‘‘very likely’’ to mean greater
than 90 percent probability, and
‘‘likely’’ to mean greater than 66 percent
probability; see Solomon et al. 2007, pp.
22–23). Some of the IPCC’s key
projections of global climate and its
related effects include: (1) It is virtually
certain there will be warmer and more
frequent hot days and nights over most
of the earth’s land areas; (2) it is very
likely there will be increased frequency
of warm spells and heat waves over
most land areas; (3) it is very likely that
the frequency of heavy precipitation
events, or the proportion of total rainfall
from heavy falls, will increase over most
areas; and (4) it is likely the area
affected by droughts will increase, that
intense tropical cyclone activity will
increase, and that there will be
increased incidence of extreme high sea
level (IPCC 2007b, p. 8, Table SPM.2).
More recently, the IPCC published
additional information that provides
further insight into observed changes
since 1950, as well as projections of
extreme climate events at global and
broad regional scales for the middle and
end of this century (IPCC 2011, entire).
Various changes in climate may have
direct or indirect effects on species.
These may be positive, neutral, or
negative, and they may change over
time, depending on the species and
other relevant considerations, such as
interactions of climate with other
variables such as habitat fragmentation
(for examples, see Franco et al. 2006;
IPCC 2007, pp. 8–14, 18–19; Forister et
al. 2010; Galbraith et al. 2010; Chen et
al. 2011). In addition to considering
individual species, scientists are
evaluating possible climate changerelated impacts to, and responses of,
ecological systems, habitat conditions,
and groups of species; these studies
include acknowledgement of
uncertainty (e.g., Deutsch et al. 2008;
Berg et al. 2009; Euskirchen et al. 2009;
McKechnie and Wolf 2009; Sinervo et
al. 2010; Beaumont et al. 2011;
McKelvey et al. 2011; Rogers and
Schindler 2011).
Many analyses involve elements that
are common to climate change
vulnerability assessments. In relation to
climate change, vulnerability refers to
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
the degree to which a species (or
system) is susceptible to, and unable to
cope with, adverse effects of climate
change, including climate variability
and extremes. Vulnerability is a
function of the type, magnitude, and
rate of climate change and variation to
which a species is exposed, its
sensitivity, and its adaptive capacity
(IPCC 2007a, p. 89; see also Glick et al.
2011, pp. 19–22). There is no single
method for conducting such analyses
that applies to all situations (Glick et al.
2011, p. 3). We use our expert judgment
and appropriate analytical approaches
to weigh relevant information, including
uncertainty, in our consideration of
various aspects of climate change.
As is the case with all stressors that
we assess, even if we conclude that a
species is currently affected or is likely
to be affected in a negative way by one
or more climate-related impacts, it does
not necessarily follow that the species
meets the definition of an ‘‘endangered
species’’ or a ‘‘threatened species’’
under the Act. If a species is listed as
an endangered or threatened species,
knowledge regarding its vulnerability to,
and known or anticipated impacts from,
climate-associated changes in
environmental conditions can be used
to help devise appropriate strategies for
its recovery.
The IPCC predicts that the resiliency
of many ecosystems is likely to be
exceeded this century by an
unprecedented combination of climate
change, associated disturbances (e.g.,
flooding, drought, wildfire, and insects),
and other global drivers (IPCC 2007, pp.
31–33). With medium confidence, IPCC
predicts that approximately 20 to 30
percent of plant and animal species
assessed by the IPCC so far are likely to
be at an increased risk of extinction if
increases in global average temperature
exceed 1.5 to 2.5 °C (3 to 5 °F) (IPCC
2007, p. 48).
Regional projections indicate the
Southwest, including southern Utah,
may experience the greatest temperature
increase of any area in the lower 48
States (IPCC 2007, p. 30). Drought
probability is predicted to increase in
the Southwest (Karl et al. 2009, pp. 129–
134), with summers warming more than
winters, and annual temperature
increasing approximately 2.2 °C (4 °F)
by 2050 (Ray et al. 2008, p. 29).
Additionally, the number of days over
32 °C (90 °F) could double by the end
of the century (Karl et al. 2009, p. 34).
Projections also show declines in
snowpack across the West, with the
most dramatic declines at lower
elevations (below 2,500 m (8,200 ft))
(Ray et al. 2008, p. 29). A 10 to 30
percent decrease in precipitation in

mid-latitude western North America is
projected by the year 2050, based on an
ensemble of 12 climate models (Milly et
al. 2005, p. 1). Overall, future
projections for the Southwest include
increased temperatures; more intense
and longer-lasting heat waves; and
increased probability of drought
exacerbated by higher temperatures,
heavier downpours, increased flooding,
and increased erosion (Karl et al. 2009,
pp. 129–134).
Utah is projected to warm more than
the average for the entire globe
(Governor’s Blue Ribbon Advisory
Council on Climate Change (GBRAC)
2008, p. 14). The expected
consequences of this warming are fewer
frost days, longer growing seasons, and
more heat waves (GBRAC 2008, p. 14).
For Utah, the projected increase in
annual mean temperature by year 2100
is about 4.5 °C (8 °F) (GBRAC 2008, p.
14). Because of increased temperature,
Utah soils are expected to dry more
rapidly (GBRAC 2008, p. 20); this is
likely to result in reduced soil moisture
levels in CPSD tiger beetle habitat.
Utah is projected to have more
frequent heavy precipitation events,
separated by longer dry spells as a result
of climate change (GBRAC 2008, p. 15).
Drought is a localized dry spell. Drought
conditions are a threat to the CPSD tiger
beetle, as rainfall indirectly controls
population size and the changing
dynamics of the species (Knisley and
Gowan 2009, p. 8).
Previous drought-like conditions have
resulted in drastic CPSD tiger beetle
population declines. For example, low
rainfall amounts from 2001 to 2003
resulted in reduced adult numbers in
2004 and 2005 (Knisley and Gowan
2008, p. 8). Conversely, high adult
numbers in 1996 and 2002 followed
several years of higher than average
rainfall (Knisley and Gowan 2008, p. 8).
These observed population responses to
rainfall are most likely caused by
reductions and increases in prey and
soil moisture. Prey is more abundant
during wet years, and this reduces the
effects of starvation, decreases
development time, and increases
fecundity (Knisley and Hill 2001, p.
391). Soil moisture seems to have the
greatest effect on oviposition and larval
survival. As stated in Factor A, water is
limiting to tiger beetles in CPSD, and
this is evidenced by the fact that in one
experiment water supplementation
increased larval CPSD tiger beetle
survival by 10 percent (Knisley and
Gowan 2006, p. 7).
In summary, the limited geographic
range of CPSD tiger beetle to highelevation sand dunes and swales within
the CPSD geologic feature limits the

1981, p. 131; Lande 1993, p. 912). CPSD
tiger beetle is vulnerable to extinction
due to: (1) Demographic stochasticity
due to its small population size; (2)
environmental stochasticity due to
continued small perturbations caused
by ongoing modification and
curtailment of its habitat and range from
ORV use; and (3) the chance of random
catastrophe such as an extended
drought.
Small populations also can be
vulnerable due to a lack of genetic
diversity (Shaffer 1981, p. 132). We have

diversity of CPSD tiger beetle. A

ability of the species to adapt by shifting
its range in response to changing
climatic conditions. CPSD tiger beetle
survival and reproduction, as described
above, are highly dependent upon soil
moisture, which in turn is dependent
upon climatic conditions (precipitation
and temperature). Climate change is
predicted to increase temperatures and
increase the likelihood and duration of
drought conditions in Utah. Both of
these effects will reduce soil moisture in
CPSD and impact CPSD tiger beetle, and
for this reason, we conclude that
environmental changes resulting from
climate change, including drought, will
be a threat to this species in the future.

effects of climate change result in
increased temperatures which dry soils
more quickly. ORV use can reduce soil
moisture by churning up soils and
exposing the moisture that is locked up
between soil particles, and it can also
compact soil, which reduces water
infiltration and reduces moisture
retention in soils. Cumulatively,
reduced precipitation and increased
evaporation (caused by the droughtrelated effects of climate change), and
soil compaction and soil exposure
(caused by ORV use) will further dry
soils that are already moisture limited.
This drying could result in a further
shrinking of available CPSD tiger beetle
habitat and thus decrease population
size, because less habitat will be
suitable for larval tiger beetles and
because drying of habitat reduces prey
abundance. For these reasons, we find
that ORV use and drought-related effects
of climate change are a threat to the
species both independently (presently
in the case of ORV use) and
cumulatively in the future.
Summary of Factor E
Wind action created and continues to
shape the CPSD (Ford et al. 2010, p.
387). Sand dune movement naturally
occurs in this system as wind action
continues to shape the dunes. Dune
movement can result in a change in
suitable habitat conditions (Knisley and
Gowan 2008, pp. 21–22); however, it is
likely that dune movement is
uncovering potential habitat as well as
covering previously occupied habitat
(e.g., Gregory 1950, p. 188). CPSD tiger
beetle evolved in a dynamic dunedominated system, and we have no
evidence to suggest that the rate of dune
movement is increasing or decreasing.
Thus, we have no information
indicating that dune movement is a
threat to this species, now or is likely to
become so in the future.
Utah is predicted to have increased
temperatures and more frequent heavy
precipitation events, separated by longer
dry spells, as a result of climate change
(GBRAC 2008, p. 15). Utah soils are
expected to dry more rapidly as a result
of increased temperatures (GBRAC
2008, p. 20). Drought duration and
intensity in CPSD will likely increase in
the future, magnifying the soil moisture
reductions expected from temperature
increases alone. Precipitation and soil
moisture levels currently limit the CPSD
tiger beetle population in CPSD (Knisley
and Gowan 2006, p. 7), and reductions
in soil moisture associated with climate
change and drought will further reduce
the CPSD tiger beetle population size.
Based on the analysis in Factor E, we
find environmental changes resulting
E:\FR\FM\02OCP3.SGM
02OCP3
60224
Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
from climate change and drought, will
become threats to the CPSD tiger beetle
in the future.
The restricted range of the species
does not constitute a threat in itself.
However, the species’ small population
size makes the species more vulnerable
to extinction due to demographic
stochasticity, environmental
stochasticity, and random ecatastrophe,
when combined with the specific
threats of ORV use, drought, and climate
change. Therefore, we consider its small
population size to be a threat to the
species when combined with other
stressors and threats.
Threats can work in concert with one
another to cumulatively create
conditions that will impact CPSD tiger
beetle beyond the scope of each
individual threat. Climate change,
drought, and ORV use all act upon
CPSD tiger beetle through a similar
mechanism: The drying of soils. As we
discussed, soil moisture is a critical
factor for desert tiger beetles (Knisley
and Juliano 1988, entire) and water and
soil moisture are both currently limiting
CPSD tiger beetle (Knisley and Gowan
2006, p. 7). Reduced precipitation,
increased evaporation, soil compaction,
and soil exposure act cumulatively on
CPSD tiger beetle and its habitat. For
these reasons, we find ORV use,
environmental changes resulting from
climate change, and drought are threats
to the species both independently
(presently in the case of ORV use) and
cumulatively. The best scientific and
commercial information available
indicates that other natural or manmade
factors affecting its continued existence
are a threat the CPSD tiger beetle, now
and are likely to continue to be so in the
future.
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
Determination
We have carefully assessed the best
scientific and commercial information
available regarding the past, present,
and future threats to CPSD tiger beetle.
The Act defines an endangered species
as any species that is ‘‘in danger of
extinction throughout all or a significant
portion of its range’’ and a threatened
species as any species ‘‘that is likely to
become endangered throughout all or a
significant portion of its range within
the foreseeable future.’’ Under the Act
and our implementing regulations, a
species may warrant listing if it is in
danger of extinction or likely to become
so throughout all or a significant portion
of its range. CPSD tiger beetle is highly
restricted in its range, threats occur
throughout its range, and are not
restricted to any particular significant
portion of that range. Accordingly, our
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
assessment and determination applies to
the species throughout its entire range.
CPSD tiger beetle has one of the
smallest geographical ranges of any
known insect (Romey and Knisley 2002,
p. 170). It is restricted to the CPSD
geologic feature and occupies only 202
ha (500 ac) (Morgan et al. 2000, p. 1109).
Within CPSD, CPSD tiger beetle occur
sporadically throughout the dunes, but
only consistently exist in two
populations that are separated by 4.8 km
(3 mi). The northern population is not
self-sustaining (Knisley 2001, p. 9) and
likely persists because of periodic
dispersal from the central population.
Extremely low numbers and a highly
restricted geographic range make CPSD
tiger beetle particularly susceptible to
becoming in danger of extinction due to
existing threats and threats in the
foreseeable future.
ORV use and small population effects,
in combination with other stressors, are
threats to the species (see Factors A, D,
and E). These factors pose immediate
threats to the species because they are
ongoing. ORV use, small population
effects, climate change and drought, and
the cumulative impacts of ORV use and
climate change and drought will
threaten the species in the foreseeable
future (see Factors A, D, and E).
Despite ongoing threats, the adult
CPSD tiger beetle population size has
shown a stable or slightly increasing
trend since 2003, but overall trend since
1992 suggests that the population is in
decline.
Recreational ORV use has reduced the
amount of habitat available to CPSD
tiger beetle and in this way suppresses
the species population size. However, as
the past 9 years of population data
suggest, it is unlikely that the threat of
ORV use will cause imminent extinction
for the species. It is more likely that,
absent the protections of the Act, ORV
use will continue to suppress the CPSD
tiger beetle population size, and future
drought conditions associated with
climate change would act cumulatively
with ORV use upon an extremely small
population, causing endangerment.
Because endangerment in this case is
‘‘in the foreseeable future’’ and the
species is currently (over about the last
5 years) experiencing a stable or
increasing population trend, we do not
consider CPSD tiger beetle to be
presently on the brink of extinction, but
likely to become so in the future
(Capone 2012, entire).
Therefore, on the basis of the best
available scientific and commercial
information, we propose listing CPSD
tiger beetle as a threatened species in
accordance with sections 3(6) and
4(a)(1) of the Act. Because threats are
PO 00000
Frm 00018

distributed across the limited range of
the species, we have determined that
the CPSD tiger beetle is a threatened
species throughout all of its range.
Available Conservation Measures
Conservation measures provided to
species listed as endangered or
threatened under the Act include
recognition, recovery actions,
requirements for Federal protection, and
prohibitions against certain practices.
Listing results in public awareness and
conservation by Federal, State, Tribal,
and local agencies, private
organizations, and individuals. The Act
encourages cooperation with the States
and requires that recovery actions be
carried out for all listed species. The
protection required by Federal agencies
and the prohibitions against certain
activities are discussed, in part, below.
The primary purpose of the Act is the
conservation of endangered and
threatened species and the ecosystems
upon which they depend. The ultimate
goal of such conservation efforts is the
recovery of these listed species, so that
they no longer need the protective
measures of the Act. Subsection 4(f) of
the Act requires the Service to develop
and implement recovery plans for the
conservation of endangered and
threatened species. The recovery
planning process involves the
identification of actions that are
necessary to halt or reverse the species’
decline by addressing the threats to its
survival and recovery. The goal of this
process is to restore listed species to a
point where they are secure, selfsustaining, and functioning components
of their ecosystems.
Recovery planning includes the
development of a recovery outline
shortly after a species is listed,
preparation of a draft and final recovery
plan, and revisions to the plan as
significant new information becomes
available. The recovery outline guides
the immediate implementation of urgent
recovery actions and describes the
process to be used to develop a recovery
plan. The recovery plan identifies sitespecific management actions that will
achieve recovery of the species,
measurable criteria that determine when
a species may be downlisted or delisted,
and methods for monitoring recovery
progress. Recovery plans also establish
a framework for agencies to coordinate
their recovery efforts and provide
estimates of the cost of implementing
recovery tasks. Recovery teams
(comprising species experts, Federal
and State agencies, nongovernmental
organizations, and stakeholders) are
often established to develop recovery
plans. When completed, the recovery

our Web site (https://www.fws.gov/
endangered), or from our Utah Field
Office (see FOR FURTHER INFORMATION
CONTACT).
Implementation of recovery actions
generally requires the participation of a
broad range of partners, including other
Federal agencies, States, Tribes,
nongovernmental organizations,
businesses, and private landowners.
Examples of recovery actions include
habitat restoration (e.g., restoration of
native vegetation), research, captive
propagation and reintroduction, and
outreach and education. The recovery of
many listed species cannot be
accomplished solely on Federal lands
because their range may occur primarily
or solely on non-Federal lands. To
achieve recovery of these species
requires cooperative conservation efforts
on private, State, and Tribal lands.
If this species is listed, funding for
recovery actions will be available from
a variety of sources, including Federal
budgets, State programs, and cost share
grants for non-Federal landowners, the
academic community, and
nongovernmental organizations. In
addition, pursuant to section 6 of the
Act, the State of Utah would be eligible
for Federal funds to implement
management actions that promote the
protection and recovery of CPSD tiger
beetle. Information on our grant
programs that are available to aid
species recovery can be found at:
https://www.fws.gov/grants.
Although CPSD tiger beetle is only
proposed for listing under the Act at
this time, please let us know if you are
interested in participating in recovery
efforts for this species. Additionally, we
invite you to submit any new
information on this species whenever it
becomes available and any information
you may have for recovery planning
purposes (see FOR FURTHER INFORMATION
CONTACT).
Section 7(a) of the Act requires
Federal agencies to evaluate their
actions with respect to any species that
is proposed or listed as endangered or
threatened and with respect to its
critical habitat, if any is designated.
Regulations implementing this
interagency cooperation provision of the
Act are codified at 50 CFR part 402.
Section 7(a)(4) of the Act requires
Federal agencies to confer with the
Service on any action that is likely to
jeopardize the continued existence of a
species proposed for listing or result in
destruction or adverse modification of
proposed critical habitat. If a species is
listed subsequently, section 7(a)(2) of
the Act requires Federal agencies to
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
ensure that activities they authorize,
fund, or carry out are not likely to
jeopardize the continued existence of
the species or destroy or adversely
modify its critical habitat. If a Federal
action may affect a listed species or its
critical habitat, the responsible Federal
agency must enter into formal
consultation with the Service.
Federal agency actions within the
species’ habitat that may require
conference or consultation or both as
described in the preceding paragraph
include management and any other
landscape altering activities on Federal
lands administered by the BLM;
construction and management of gas
pipeline and power line rights-of-way
by the Federal Energy Regulatory
Commission; and construction and
maintenance of roads or highways by
the Federal Highway Administration.
We may issue permits to carry out
otherwise prohibited activities
involving endangered and threatened
wildlife species under certain
circumstances. Regulations governing
permits are codified at 50 CFR 17.32 for
threatened species. With regard to
endangered wildlife, a permit must be
issued for the following purposes: For
scientific purposes, to enhance the
propagation or survival of the species,
and for incidental take in connection
with otherwise lawful activities.
Questions regarding whether specific
activities would constitute a violation of
section 9 of the Act should be directed
to the U.S. Fish and Wildlife Service,
Utah Field Office (see FOR FURTHER
INFORMATION CONTACT). Requests for

listed animals and general inquiries
regarding prohibitions and permits may

Conservation, as defined under
section 3 of the Act, means to use all
methods and procedures that are
necessary to bring an endangered or
threatened species to the point at which
the measures provided pursuant to the
Act are no longer necessary. Such
methods and procedures include, but
are not limited to, all activities
associated with scientific resources
management such as research, census,
law enforcement, habitat acquisition
and maintenance, propagation, live
trapping, and transplantation, and, in
the extraordinary case where population
pressures within a given ecosystem
cannot be otherwise relieved, may
include regulated taking.
Critical habitat receives protection
under section 7 of the Act through the
requirement that Federal agencies
ensure, in consultation with the Service,
that any action they authorize, fund, or
carry out is not likely to result in the
destruction or adverse modification of
critical habitat. The designation of
critical habitat does not affect land
ownership or establish a refuge,
wilderness, reserve, preserve, or other
conservation area. Such designation
does not allow the government or public
to access private lands. Such
designation does not require
implementation of restoration, recovery,
or enhancement measures by nonFederal landowners. Where a landowner
seeks or requests Federal agency
funding or authorization for an action
that may affect a listed species or
critical habitat, the consultation
requirements of section 7(a)(2) would
apply, but even in the event of a
destruction or adverse modification
finding, the obligation of the Federal
action agency and the landowner is not
to restore or recover the species, but to
implement reasonable and prudent
alternatives to avoid destruction or
adverse modification of critical habitat.
Under the first prong of the Act’s
definition of critical habitat, areas
within the geographical area occupied
by the species at the time it was listed
are included in a critical habitat
designation if they contain physical or
biological features (1) which are
essential to the conservation of the
species and (2) which may require
special management considerations or
protection. For these areas, critical
habitat designations identify, to the
extent known using the best scientific
and commercial data available, those
physical or biological features that are
essential to the conservation of the

species (such as space, food, cover, and
protected habitat). In identifying those
physical and biological features within
an area, we focus on the Primary
Constituent Elements (PCEs), such as
roost sites, nesting grounds, seasonal
wetlands, water quality, tide, and soil
type, that are essential to the
conservation of the species.
Under the second prong of the Act’s
definition of critical habitat, we can
designate critical habitat in areas
outside the geographical area occupied
by the species at the time it is listed,
upon a determination that such areas
are essential for the conservation of the
species. For example, an area currently
occupied by the species but that was not
occupied at the time of listing may be
essential to the conservation of the
species and may be included in the
critical habitat designation. We
designate critical habitat in areas
outside the geographical area occupied
by a species only when a designation
limited to its range would be inadequate
to ensure the conservation of the
species.
Section 4 of the Act requires that we
designate critical habitat on the basis of
the best scientific data available.
Further, our Policy on Information
Standards under the Act (published in
the Federal Register on July 1, 1994 (59
FR 34271)), the Information Quality Act
(section 515 of the Treasury and General
Government Appropriations Act for
Fiscal Year 2001 (Pub. L. 106–554; H.R.
5658)), and our associated Information
Quality Guidelines, provide criteria,
establish procedures, and provide
guidance to ensure that our decisions
are based on the best scientific data
available. They require our biologists, to
the extent consistent with the Act and
with the use of the best scientific data
available, to use primary and original
sources of information as the basis for
recommendations to designate critical
habitat.
When we are determining which areas
should be designated as critical habitat,
our primary source of information is
generally the information developed
during the listing process for the
species. Additional information sources
may include the recovery plan for the
species, articles in peer-reviewed
journals, conservation plans developed
by States and counties, scientific status
surveys and studies, biological
assessments, other unpublished
materials, or experts’ opinions or
personal knowledge.
Habitat is dynamic, and species may
move from one area to another over
time. We recognize that critical habitat
designated at a particular point in time
may not include all of the habitat areas
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
that we may later determine are
necessary for the recovery of the
species. For these reasons, a critical
habitat designation does not signal that
habitat outside the designated area is
unimportant or may not be needed for
recovery of the species. Areas that are
important to the conservation of the
species, both inside and outside the
critical habitat designation, will
continue to be subject to: (1)
Conservation actions implemented
under section 7(a)(1) of the Act, (2)
regulatory protections afforded by the
requirement in section 7(a)(2) of the Act
for Federal agencies to ensure their
actions are not likely to jeopardize the
continued existence of any endangered
or threatened species, and (3) the
prohibitions of section 9 of the Act if
actions occurring in these areas may
affect the species. Federally funded or
permitted projects affecting listed
species outside their designated critical
habitat areas may still result in jeopardy
findings in some cases. These
protections and conservation tools will
continue to contribute to recovery of
this species. Similarly, critical habitat
designations made on the basis of the
best available information at the time of
designation will not control the
direction and substance of future
recovery plans, Habitat Conservation
Plans (HCPs), or other species
conservation planning efforts if new
information available at the time of
these planning efforts calls for a
different outcome.
Physical or Biological Features
In accordance with section 3(5)(A)(i)
and 4(b)(1)(A) of the Act and regulations
at 50 CFR 424.12, in determining which
areas within the geographical area
occupied by the species at the time of
listing to designate as critical habitat,
we consider the physical or biological
features essential to the conservation of
the species and which may require
special management considerations or
protection. These include, but are not
limited to:
(1) Space for individual and
population growth and for normal
behavior;
(2) Food, water, air, light, minerals, or
other nutritional or physiological
requirements;
(3) Cover or shelter;
(4) Sites for breeding, reproduction, or
rearing (or development) of offspring;
and
(5) Habitats that are protected from
disturbance or are representative of the
historical, geographical, and ecological
distributions of a species.
We derive the specific physical or
biological features required for CPSD
PO 00000
Frm 00020
Fmt 4701
Sfmt 4702
tiger beetle from studies of this species’
habitat, ecology, and life history as
described below. We have determined
that CPSD tiger beetle requires the
following physical or biological
features:
Space for Individual and Population
Growth
Dune System—CPSD consists of a
series of high, mostly barren, dry dune
ridges separated by lower, moister, and
more vegetated interdunal swales
(Romey and Knisley 2002, p. 170). The
CPSD tiger beetle requires
interconnected dune and swale habitats
for thermoregulation, foraging,
reproduction, and larval development.
Adult CPSD tiger beetles use most of the
dune area from the swales (low place
between sand dunes) to the upper dune
slope for foraging and thermoregulation.
Larval CPSD tiger beetles are more
restricted to moist, vegetated swale
areas (Knisley and Hill 2001, p. 386).
Therefore, based on the information
above we identify sand dunes and
swales within the CPSD geologic feature
as an essential physical or biological
feature for this species.
Climate—The CPSD tiger beetle
occurs only at the CPSD geologic feature
in southern Utah. CPSD elevation ranges
from a low of 1,710 m (5,620 ft) to a
high of 2,090 m (6,850 ft) (Ford et al.
2010, p. 381). The nearest weather
station, in Kanab, Utah, has a mean
annual temperature of 12.4 °C (54.4 °F)
and mean annual precipitation of 33.8
cm (13.3 inches) with winter-summer
precipitation peaks and spring-autumn
drought (Ford et al. 2010, p. 381). These
climatic conditions are influenced, in
part, by elevation. Rainfall and the
associated increase in soil moisture
have a positive effect on CPSD tiger
beetle oviposition and survivorship
(Knisley and Hill 2001, p. 391) and the
areas in the dune field with the highest
soil moisture contain the highest
densities of larvae (Knisley and Gowan
2011, p. 22). Because the CPSD tiger
beetle has evolved in these climatic
conditions and because precipitation
and moisture are important to survival,
we identify suitable precipitation
regimes, a dry spring and fall, and
winter and summer precipitation as
essential physical or biological features
for this species.
Food, Water, Air, Light, Minerals, or
Other Nutritional or Physiological
Requirements
Food—CPSD tiger beetle are predatory
insects. Adults are active, visual hunters
that use their large mandibles to capture
and eat small arthropods. Adults
primarily forage on dune faces and
E:\FR\FM\02OCP3.SGM
02OCP3
Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
swale edges (Hill and Knisley 1996, p.
9). Adults are food limited in some
years, which results in reduced
fecundity (Knisley and Gowan 2008, p.
19). Larvae are sedentary predators that
live in permanent burrows in the
ground and use large mandibles to
capture small arthropods that pass near
their burrow. CPSD tiger beetle feed
primarily on ants, flies, and other small
arthropods (Knisley and Hill 1993, p.
13).
In summary, CPSD tiger beetle is food
limited in some years. Both adults and
larvae use their large mandibles to
capture arthropods. Their primary prey
are ants, flies, and other small
arthropods. Therefore, based on the
information above, we identify an
abundant and diverse arthropod prey
base to be an essential physical or
biological feature for this species.
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
Cover or Shelter
Adult Burrows—Adult CPSD tiger
beetle use cover or shelter to help
maintain internal body temperatures
(thermoregulation). During peak spring
and fall activity, when it is sunny,
adults are usually active early (9 a.m.–
2 p.m.) and again in late afternoon (4
p.m.–7 p.m.) (Knisley and Hill 1993,
pp.13–14). They dig and reside in the
sand in burrows to avoid unfavorable
weather conditions such as hot midafternoons or daytime conditions that
are cool or rainy (Knisley and Hill 1993,
p. 14). Shade provided by vegetative
cover also is important for
thermoregulation during warmer
periods (Knisley 2012, pers. comm.).
Therefore, based on the information
above, we identify sand dunes and
vegetation as an essential physical or
biological feature for this species.
Sites for Breeding, Reproduction, or
Rearing (or Development) of Offspring
Larval Beds—Adult females
determine the larval microhabitat by
their selection of an oviposition site
(Knisley and Gowan 2011, p. 6). Newly
hatched larvae construct burrows in
sand soils at the site of oviposition and
subsequently pass through three larval
stages (each stage is called an ‘‘instar’’)
before pupating and then emerging to
the adult form. Larvae remain in the
same burrow throughout their
development and only rarely move
outside of their burrow to dig a new
burrow in a more favorable location
(Knisley and Hill 1996, p. 11).
Most larvae occur within the swale
bottoms and up the lower slopes of the
dunes, particularly where the soil or
subsoil is moist most of the time
(Knisley and Hill 1996, p. 11; Knisley
and Gowan 2011, p. 22). Larvae
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
primarily inhabit areas with 3 to 25
percent soil moisture (Romney and
Knisley 2002, p. 172). Soil moisture is
critical to larval CPSD tiger beetle
survival. Drying or desiccation can kill
tiger beetles (Knisley and Juliano 1998,
p. 1990), and almost no larvae survive
below 3 percent soil moisture (Romen
and Knisley 2002, p. 172). Water tends
to be so limiting in CPSD that water
supplementation increases larval CPSD
tiger beetle survival by 10 percent
(Knisley and Gowan 2006, p. 7). We are
not aware of an upper limit, in terms of
soil moisture, where increases in soil
moisture are detrimental to larval CPSD
tiger beetle survival.
Larvae are most common in swales
with a relatively high total percent
vegetation cover (means of 23 to 57
percent) (Knisley and Hill 2001, p. 389).
The swale vegetation supports the prey
base of ants, flies, and other prey upon
which larvae depend. Low or no
vegetation results in a reduced prey
base. Vegetative cover above 57 percent
tends to stabilize sediments too much
and may prevent adults from
ovipositing (Knisley 2012, pers. comm.).
In summary, adult ovipositing
determines the habitats used by larval
CPSD tiger beetle. Soil moisture and
prey availability are essential for larval
growth and survival. Vegetation
supports the prey base; however, too
much vegetation cover can make habitat
unsuitable for ovipositing. Therefore,
based on the information above, we
identify swale habitat, soil moisture, an
abundant and diverse prey base, and 23
to 57 percent vegetation cover as the
essential physical or biological features
for this species.
Primary Constituent Elements for CPSD
Tiger Beetle
Under the Act and its implementing
regulations, we are required to identify
the physical or biological features
essential to the conservation of CPSD
tiger beetle in areas occupied at the time
of listing, focusing on the features’
PCEs. We consider PCEs to be the
elements of physical or biological
features that are all needed to provide
for a species’ life-history processes and
are essential to the conservation of the
species.
Based on our current knowledge of
the physical or biological features and
habitat characteristics required to
sustain the species’ life-history
processes, we determine that the PCEs
specific to CPSD tiger beetle are:
Dynamic sand dunes and swales within
the Coral Pink Sand Dunes geologic
feature that have:
Æ Elevations from 1,710 to 2,090 m;
PO 00000
Frm 00021
Fmt 4701
Sfmt 4702
60227
Æ Appropriate levels of moisture and
compaction to allow for burrowing
(greater than 3 percent); and
Æ Vegetative cover of 23–57% that
allows for ovipositing, adult
thermoregulation, and abundant prey.
With this proposed designation of
critical habitat, we intend to identify the
physical or biological features essential
to the conservation of the species,
through the identification of PCEs
sufficient to support the life-history
processes of the species. All units and
subunits proposed for designation as
critical habitat are currently occupied
by CPSD tiger beetle and contain the
PCEs sufficient to support the lifehistory needs of the species.
Special Management Considerations or
Protection
When designating critical habitat, we
assess whether the specific areas within
the geographical area occupied by the
species at the time of listing contain
features which are essential to the
conservation of the species and which
may require special management
considerations or protection. A detailed
discussion of threats to CPSD tiger
beetle and its habitat can be found in
the Summary of Factors Affecting the
Species section.
The primary threats impacting the
physical and biological features
essential to the conservation of CPSD
tiger beetle that may require special
management considerations or
protection within the proposed critical
habitat include, but are not limited to,
ORV use, drought, and climate change,
and the cumulative effects of all of these
threats.
The features essential to the
conservation of this species (sand
dunes, moist and vegetated swales, and
prey species) may require special
management considerations or
protection to reduce threats. Extremely
low numbers and a highly restricted
geographic range make CPSD tiger
beetle particularly susceptible to
extinction in the foreseeable future.
Special management considerations or
protections are required within critical
habitat areas to address threats.
Management activities that could
ameliorate threats include (but are not
limited to): The establishment of a
second self-sustaining population;
regulations and/or agreements that
balance conservation with ORV use in
areas that would affect the species; the
designation of additional protected
areas with specific provisions and
protections for the species; and the
elimination or avoidance of activities
that alter the soil moisture, vegetation
community, or prey base in swale

habitat. These management activities
would protect the PCEs for the species
by preventing the loss of habitat and
individuals, protecting dune and swale
habitat, and managing for appropriate
levels and types of disturbance.
Criteria Used To Identify Critical
Habitat
As required by section 4(b)(1)(A) of
the Act, we use the best scientific and
commercial data available to designate
critical habitat. We review available
information pertaining to the habitat
requirements of the species. In
accordance with the Act and its
implementing regulation at 50 CFR
424.12(e), we consider whether
designating additional areas—outside
those currently occupied as well as
those occupied at the time of listing—
are necessary to ensure the conservation
of the species. We are proposing to
designate critical habitat concurrent
with listing in areas within the
geographical area occupied by the
species.
We are proposing to designate all
currently occupied habitat as critical
habitat—any degradation of existing
occupied habitat would further increase
CPSD tiger beetle’s susceptibility to
extinction. CPSD tiger beetle primarily
occurs in two populations that are
separated by 4.8 km (3 mi) of dunes. We
include the 4.8-km (3-mi) dune segment
that separates the two populations
because dispersal is likely important for
the long term-survival of the species
(see Habitat, above), and this central
dune segment is used by dispersing
adults. Comprehensive surveys have not
been conducted in this area for 20 years,
and we have no information to confirm
the present occurrence of larval CPSD
tiger beetles and swale habitat.
We delineated the critical habitat unit
boundaries for CPSD tiger beetle using
the following steps:
(1) In determining what areas were
occupied by CPSD tiger beetle, we used
data collected by Dr. Barry Knisley (Hill
and Knisley 1993 pp. 7–10; Knisley and
Hill 1994 pp. 5–10; Knisley and Gowan
2005, pp. 7–8; Knisley and Gowan 2011
p. 29) to map the central and northern
populations of CPSD tiger beetle using
ArcMap 9.3.1.
(2) We delineated proposed critical
habitat areas by creating polygons
around each population. Because of the
narrowness of the actual CPSD area (less
than 1.6 km (1 mi)) and the shifting and
movement of habitat within the CPSD
system, we included the entire width of
the CPSD area surrounding each
population.
(3) We then included a dispersal
corridor, the dune area between the
central and northern populations. We
delineated the dispersal corridor as the
entirety of the dune area between the
central and northern populations
because the entirety of the dune area
could be used by dispersing adults.
When determining proposed critical
habitat boundaries, we made every
effort to avoid including developed
areas such as lands covered by
buildings, pavement, and other
structures because such lands lack
physical or biological features for CPSD
tiger beetle. The scale of the maps we
prepared under the parameters for
publication within the Code of Federal
Regulations may not reflect the
exclusion of such developed lands. Any
such lands inadvertently left inside
critical habitat boundaries shown on the
maps of this proposed rule have been
excluded by text in the proposed rule
and are not proposed for designation as
critical habitat. Therefore, if the critical
habitat is finalized as proposed, a
Federal action involving these lands
would not trigger section 7 consultation
with respect to critical habitat and the
requirement of no adverse modification
unless the specific action would affect
the physical or biological features in the
adjacent critical habitat.
We are proposing for designation of
critical habitat lands that we have
determined are occupied at the time of
listing and contain sufficient elements
of physical or biological features to
support life-history processes essential
for the conservation of the CPSD tiger
beetle.
One unit is proposed for designation
based on sufficient elements of physical
or biological features being present to
support CPSD tiger beetle life-history
processes. This unit contains all of the
identified elements of physical or
biological features and supports
multiple life-history processes.
Proposed Critical Habitat Designation
We are proposing one unit as critical
habitat for CPSD tiger beetle. The
critical habitat area we describe below
constitutes our current best assessment
of the area that meets the definition of
critical habitat for CPSD tiger beetle.
The unit will be occupied at the time of
any listing and is currently occupied.
The approximate area of the proposed
critical habitat unit is shown in Table 2.

We present brief descriptions of the
unit, and reasons why it meets the
definition of critical habitat for CPSD
tiger beetle, below.
CPSD Unit
The Unit consists of 921 ha (2,276 ac)
of dune habitat and is located entirely
within the CPSD geologic feature (see
Proposed Regulation Promulgation,
below). The southern 310 ha (767 acres)
are located within CPSD State Park. The
VerDate Mar<15>2010

Jkt 229001
northern 610 ha (1,508 ac) are located
on BLM land.
CPSD State Park is categorized as
public land with a recreational
emphasis. The State Park encompasses
the southern 809 ha (2,000 ac) of the
CPSD geologic feature. The habitat
consists of a series of high, mostly
barren, dry dune ridges separated by
lower, moister, and more vegetated
interdunal swales (Romey and Knisley
2002, p. 170). The proposed unit

overlaps an existing 84 ha (207 ac) of
State Park nonmotorized area
(Conservation Area A). The remaining
227 ha (560 ac) of the State Park are
open to ORV use.
The BLM Kanab Resource Area
manages the northern 610 ha (1,508 ac)
of the CPSD geologic feature (BLM 2000,
p. 14). The BLM portion of the proposed
Unit is characterized by dunes and
swales that contain dense pockets of
vegetation. In general, dunes and swales

02OCP3
Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
in this unit are more stable and more
highly vegetated than those in the State
Park (Ford et al. 2010, pp. 387–392).
The proposed unit overlaps an existing
150 ha (370 ac) of BLM nonmotorized
area (Conservation Area B). The
remaining 460 ha (1,138 ac) of BLM
land are open to ORV use.
This unit currently has all the
physical and biological features
essential to the conservation of the
species. This unit requires special
management considerations or
protections from the threats of ORV use,
drought, and climate change. It is
located within the appropriate elevation
range, and it contains numerous moist
and vegetated swales near dunes. Adult
and larval CPSD tiger beetle have
occurred throughout the proposed State
Park owned portion of the Unit
continuously for the past 20 years
(Knisley and Gowan 2011, p. 8), and
small numbers of adult and larval CPSD
tiger beetles occupy the northern extent
within the BLM Conservation Area B
habitat (Knisley and Gowan 2011, p. 9).
The central portion of the proposed unit
between Conservation Areas A and B
may contain suitable swale habitat and
larval beetles; however, comprehensive
surveys have not been conducted in the
past 20 years, and we have no
information to confirm the present
occurrence of larval CPSD tiger beetles.
However, the central portion of the
proposed unit is used by dispersing
adult beetles, and likely serves as a link
between the two known populations.
Areas Outside Proposed Critical Habitat
As stated previously, we recognize
that critical habitat designated at a
particular point in time may not include
all of the habitat areas that we may later
determine are necessary for the recovery
of the species. For these reasons, a
critical habitat designation does not
signal that habitat outside the
designated area is unimportant or may
not be needed for recovery of the
species.
Only areas within the historical
distribution of CPSD tiger beetle were
considered for proposed critical habitat
because areas outside of the historical
distribution do not contain the requisite
PCEs for the species. For this reason, we
did not consider unoccupied areas
outside of the CPSD geologic feature.
We did consider the 227 ha (560 ac)
of sand dunes within CPSD State Park
that exist south of our proposed critical
habitat unit (see Figure 4 below).
However, we have no information
suggesting that this dune area was
historical habitat, or is now suitable
habitat for CPSD tiger beetle. Unlike the
areas included within the proposed
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
critical habitat unit, this southern area
has no record of CPSD tiger beetle larval
presence nor is there record of regular
adult occurrence. As we described
previously (see Habitat), wind action in
the dunes primarily blows from south to
north, and wind velocity decreases as it
moves across the sand dunes (from
south to north). This results in a
dynamic and less vegetated south Dune
area that transitions to a less dynamic
and more heavily vegetated and higher
northern Dune area (Ford et al. 2010,
pp. 387–392). The dynamic southern
area has less vegetation cover (Ford et
al. 2010, pp. 387–392) and the high
wind energy likely reduces soil
moisture levels (e.g., Lortie and
Cushman 2007, pp. 478–479). We
believe the lack of PCEs (vegetative
cover and appropriate soil moisture)
make the south Dune area unsuitable as
critical habitat (see Factor A for a
discussion of the importance of soil
moisture and vegetation).
Effects of Critical Habitat Designation
Section 7 Consultation
Section 7(a)(2) of the Act requires
Federal agencies, including the Service,
to ensure that any action they fund,
authorize, or carry out is not likely to
jeopardize the continued existence of
any endangered species or threatened
species or result in the destruction or
adverse modification of designated
critical habitat of such species. In
addition, section 7(a)(4) of the Act
requires Federal agencies to confer with
the Service on any agency action that is
likely to jeopardize the continued
existence of any species proposed to be
listed under the Act or result in the
destruction or adverse modification of
proposed critical habitat.
Decisions by the 5th and 9th Circuit
Courts of Appeals have invalidated our
regulatory definition of ‘‘destruction or
adverse modification’’ (50 CFR 402.02)
(see Gifford Pinchot Task Force v. U.S.
Fish and Wildlife Service, 378 F.3d 1059
(9th Cir. 2004) and Sierra Club v. U.S.
Fish and Wildlife Service et al., 245 F.3d
434, 442 (5th Cir. 2001)), and we do not
rely on this regulatory definition when
analyzing whether an action is likely to
destroy or adversely modify critical
habitat. Under the statutory provisions
of the Act, we determine destruction or
adverse modification on the basis of
whether, with implementation of the
proposed Federal action, the affected
critical habitat would continue to serve
its intended conservation role for the
species.
If a Federal action may affect a listed
species or its critical habitat, the
responsible Federal agency (action
PO 00000
Frm 00023
Fmt 4701
Sfmt 4702
60229
agency) must enter into consultation
with us. Examples of actions that are
subject to the section 7 consultation
process are actions on State, Tribal,
local, or private lands that require a
Federal permit (such as a permit from
the U.S. Army Corps of Engineers under
section 404 of the Clean Water Act (33
U.S.C. 1251 et seq.) or a permit from the
Service under section 10 of the Act) or
that involve some other Federal action
(such as funding from the Federal
Highway Administration, Federal
Aviation Administration, or the Federal
Emergency Management Agency).
Federal actions not affecting listed
species or critical habitat, and actions
on State, Tribal, local, or private lands
that are not federally funded or
authorized, do not require section 7
consultation.
As a result of section 7 consultation,
we document compliance with the
requirements of section 7(a)(2) through
our issuance of:
(1) A concurrence letter for Federal
actions that may affect, but are not
likely to adversely affect, listed species
or critical habitat; or
(2) A biological opinion for Federal
actions that may affect, or are likely to
adversely affect, listed species or critical
habitat.
When we issue a biological opinion
concluding that a project is likely to
jeopardize the continued existence of a
listed species and/or destroy or
adversely modify critical habitat, we
provide reasonable and prudent
alternatives to the project, if any are
identifiable, that would avoid the
likelihood of jeopardy and/or
destruction or adverse modification of
critical habitat. We define ‘‘reasonable
and prudent alternatives’’ (at 50 CFR
402.02) as alternative actions identified
during consultation that:
(1) Can be implemented in a manner
consistent with the intended purpose of
the action;
(2) Can be implemented consistent
with the scope of the Federal agency’s
legal authority and jurisdiction;
(3) Are economically and
technologically feasible; and
(4) Would, in the Director’s opinion,
avoid the likelihood of jeopardizing the
continued existence of the listed species
and/or avoid the likelihood of
destroying or adversely modifying
critical habitat.
Reasonable and prudent alternatives
can vary from slight project
modifications to extensive redesign or
relocation of the project. Costs
associated with implementing a
reasonable and prudent alternative are
similarly variable.

Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
Regulations at 50 CFR 402.16 require
Federal agencies to reinitiate
consultation on previously reviewed
actions in instances where we have
listed a new species or subsequently
designated critical habitat that may be
affected and the Federal agency has
retained discretionary involvement or
control over the action (or the agency’s
discretionary involvement or control is
authorized by law). Consequently,
Federal agencies sometimes may need to
request reinitiation of consultation with
us on actions for which formal
consultation has been completed, if
those actions with discretionary
involvement or control may affect
subsequently listed species or
designated critical habitat.
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
Application of the ‘‘Adverse
Modification’’ Standard
The key factor related to the adverse
modification determination is whether,
with implementation of the proposed
Federal action, the affected critical
habitat would continue to serve its
intended conservation role for the
species. Activities that may destroy or
adversely modify critical habitat are
those that alter the physical or
biological features to an extent that
appreciably reduces the conservation
value of critical habitat for CPSD tiger
beetle. As discussed above, the role of
critical habitat is to support life-history
needs of the species and provide for the
conservation of the species.
Section 4(b)(8) of the Act requires us
to briefly evaluate and describe, in any
proposed or final regulation that
designates critical habitat, activities
involving a Federal action that may
destroy or adversely modify such
habitat, or that may be affected by such
designation.
Activities that may affect critical
habitat, when carried out, funded, or
authorized by a Federal agency, should
result in consultation for the CPSD tiger
beetle. These activities include, but are
not limited to:
(1) Actions that would reduce soil
moisture or vegetative cover in swale
habitats. Such activities could include,
but are not limited to, continued or
increased vehicular access or pedestrian
traffic in or adjacent to occupied
habitats. These activities could reduce
soil moisture by churning up soils and
exposing the moisture that is locked up
between soil particles (beneath the
surface) to greater evaporative pressure
(Shultz 1988, p. 28) and by increasing
soil compaction (Adams et al. 1982, p.
167). These activities also could reduce
vegetative cover by trampling and
subsequently injuring or killing plants.
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
Reduced soil moisture may lead to
death of some CPSD tiger beetle larvae,
as soil moisture is the most important
factor determining larval tiger beetle
survival (Knisley and Juliano 1988,
entire). Reduced vegetative cover
adversely impacts CPSD tiger beetle
ovipositioning, adult thermoregulation,
and prey base. Low prey densities can
result in prolonged development and
decreased survivorship in larval tiger
beetles and reduced size in adults,
which lowers fecundity in females
(Pearson and Knisley 1985, p. 165;
Knisley and Juliano 1988, p. 1990).
(2) Actions that would significantly
affect dune morphology or dynamics.
Such activities could include road or
campground construction within or
adjacent to the dunes. CPSD is a
dynamic system where wind action
continues to shape the dunes and
redistribute sediment. Any significant
alteration to dune morphology or
dynamics may alter the arrangement
and amount of swale and dune habitat
available to CPSD tiger beetle.
Exemptions
Application of Section 4(a)(3) of the Act
The Sikes Act Improvement Act of
1997 (Sikes Act) (16 U.S.C. 670a)
required each military installation that
includes land and water suitable for the
conservation and management of
natural resources to complete an
integrated natural resources
management plan (INRMP) by
November 17, 2001. An INRMP
integrates implementation of the
military mission of the installation with
stewardship of the natural resources
found on the base. Each INRMP
includes:
(1) An assessment of the ecological
needs on the installation, including the
need to provide for the conservation of
listed species;
(2) A statement of goals and priorities;
(3) A detailed description of
management actions to be implemented
to provide for these ecological needs;
and
(4) A monitoring and adaptive
management plan.
Among other things, each INRMP
must, to the extent appropriate and
applicable, provide for fish and wildlife
management; fish and wildlife habitat
enhancement or modification; wetland
protection, enhancement, and
restoration where necessary to support
fish and wildlife; and enforcement of
applicable natural resource laws.
The National Defense Authorization
Act for Fiscal Year 2004 (Pub. L. 108–
136) amended the Act to limit areas
eligible for designation as critical
PO 00000
Frm 00024
Fmt 4701
Sfmt 4702
habitat. Specifically, section 4(a)(3)(B)(i)
of the Act (16 U.S.C. 1533(a)(3)(B)(i))
now provides: ‘‘The Secretary shall not
designate as critical habitat any lands or
other geographical areas owned or
controlled by the Department of
Defense, or designated for its use, that
are subject to an integrated natural
resources management plan prepared
under section 101 of the Sikes Act (16
U.S.C. 670a), if the Secretary determines
in writing that such plan provides a
benefit to the species for which critical
habitat is proposed for designation.’’
There are no Department of Defense
lands within the proposed critical
habitat designation. Thus, we are not
proposing any exemptions based on
section 4(a)(3)(B)(i).
Exclusions
Application of Section 4(b)(2) of the Act
Section 4(b)(2) of the Act states that
the Secretary shall designate and make
revisions to critical habitat on the basis
of the best available scientific data after
taking into consideration the economic
impact, national security impact, and
any other relevant impact of specifying
any particular area as critical habitat.
The Secretary may exclude an area from
critical habitat if he determines that the
benefits of such exclusion outweigh the
benefits of specifying such area as part
of the critical habitat, unless he
determines, based on the best scientific
data available, that the failure to
designate such area as critical habitat
will result in the extinction of the
species. In making that determination,
the statute on its face, as well as the
legislative history, are clear that the
Secretary has broad discretion regarding
which factor(s) to use and how much
weight to give to any factor.
Under section 4(b)(2) of the Act, we
may exclude an area from designated
critical habitat based on economic
impacts, impacts on national security,
or any other relevant impacts. In
considering whether to exclude a
particular area from the designation, we
identify the benefits of including the
area in the designation, identify the
benefits of excluding the area from the
designation, and evaluate whether the
benefits of exclusion outweigh the
benefits of inclusion. If the analysis
indicates that the benefits of exclusion
outweigh the benefits of inclusion, the
Secretary may exercise his discretion to
exclude the area only if such exclusion
would not result in the extinction of the
species.
Exclusions Based on Economic Impacts
Under section 4(b)(2) of the Act, we
consider the economic impacts of
E:\FR\FM\02OCP3.SGM
02OCP3
Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
specifying any particular area as critical
habitat. In order to consider economic
impacts, we are preparing an analysis of
the economic impacts of the proposed
critical habitat designation and related
factors.
Upon completion, copies of the draft
economic analysis will be available for
downloading from the Internet at
https://www.regulations.gov, or by
contacting the Utah Fish and Wildlife
Office directly (see FOR FURTHER
INFORMATION CONTACT section). During
the development of a final designation,
we will consider economic impacts,
public comments, and other new
information. Areas may be excluded
from the final critical habitat
designation under section 4(b)(2) of the
Act and our implementing regulations at
50 CFR 424.19.
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
Exclusions Based on National Security
Impacts
Under section 4(b)(2) of the Act, we
consider whether there are lands owned
or managed by the Department of
Defense where a national security
impact might exist.
In preparing this proposal, we have
determined that the lands within the
proposed designation of critical habitat
for CPSD tiger beetle are not owned or
managed by the Department of Defense,
and, therefore, we anticipate no impact
on national security. Consequently, the
Secretary does not propose to exercise
his discretion to exclude any areas from
the final designation based on impacts
on national security.
Exclusions Based on Other Relevant
Impacts
Under section 4(b)(2) of the Act, we
consider any other relevant impacts, in
addition to economic impacts and
impacts on national security. We
consider a number of factors, including
whether the landowners have developed
any HCPs or other management plans
for the area, or whether there are
conservation partnerships that would be
encouraged by designation of, or
exclusion from, critical habitat. In
addition, we look at any Tribal issues,
and consider the government-togovernment relationship of the United
States with Tribal entities. We also
consider any social impacts that might
occur because of the designation.
In preparing this proposal, we have
determined that there are currently no
HCPs for CPSD tiger beetle, and the
proposed designation does not include
any Tribal lands or trust resources. We
anticipate no impact on Tribal lands,
partnerships, or HCPs from this
proposed critical habitat designation. As
we described previously, a CCA exists
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
for CPSD tiger beetle (see Factor A and
D). However, we determined in Factor A
and D that this agreement is not
adequately reducing threats to the
species. Accordingly, the Secretary does
not propose to exercise his discretion to
exclude any areas from the final
designation based on other relevant
impacts.
Peer Review
In accordance with our joint policy on
peer review published in the Federal
Register on July 1, 1994 (59 FR 34270),
we will seek the expert opinions of at
least three appropriate and independent
specialists regarding this proposed rule.
The purpose of peer review is to ensure
that our listing and critical habitat
designation is based on scientifically
sound data, assumptions, and analyses.
We have invited these peer reviewers to
comment during this public comment
period on this proposed rule to list the
species as threatened and the
designation of critical habitat.
We will consider all comments and
information received during this
comment period on this proposed rule
during our preparation of a final
determination. Accordingly, the final
decision may differ from this proposal.
Public Hearings
Section 4(b)(5) of the Act provides for
one or more public hearings on this
proposal, if requested. Requests must be
received within 45 days after the date of
publication of this proposed rule in the
Federal Register. Such requests must be
sent to the address shown in FOR
FURTHER INFORMATION CONTACT. We will
schedule public hearings on this
proposal, if any are requested, and
announce the dates, times, and places of
those hearings, as well as how to obtain
reasonable accommodations, in the
Federal Register and local newspapers
at least 15 days before the hearing.
Required Determinations
Regulatory Planning and Review—
Executive Orders 12866 and 13563
Executive Order 12866 provides that
the Office of Information and Regulatory
Affairs (OIRA) in the Office of
Management and Budget will review all
significant rules. The Office of
Information and Regulatory Affairs has
determined that this rule is not
significant.
Executive Order 13563 reaffirms the
principles of E.O. 12866 while calling
for improvements in the nation’s
regulatory system to promote
predictability, to reduce uncertainty,
and to use the best, most innovative,
and least burdensome tools for
PO 00000
Frm 00025
Fmt 4701
Sfmt 4702
60231
achieving regulatory ends. The
executive order directs agencies to
consider regulatory approaches that
reduce burdens and maintain flexibility
and freedom of choice for the public
where these approaches are relevant,
feasible, and consistent with regulatory
objectives. E.O. 13563 emphasizes
further that regulations must be based
on the best available science and that
the rulemaking process must allow for
public participation and an open
exchange of ideas. We have developed
this rule in a manner consistent with
these requirements.
Regulatory Flexibility Act (5 U.S.C. 601
et seq.)
Under the Regulatory Flexibility Act
(RFA) (5 U.S.C. 601 et seq.) as amended
by the Small Business Regulatory
Enforcement Fairness Act (SBREFA) of
1996 (5 U.S.C. 801 et seq.), whenever an
agency must publish a notice of
rulemaking for any proposed or final
rule, it must prepare and make available
for public comment a regulatory
flexibility analysis that describes the
effects of the rule on small entities
(small businesses, small organizations,
and small government jurisdictions).
However, no regulatory flexibility
analysis is required if the head of the
agency certifies the rule will not have a
significant economic impact on a
substantial number of small entities.
The SBREFA amended the RFA to
require Federal agencies to provide a
certification statement of the factual
basis for certifying that the rule will not
have a significant economic impact on
a substantial number of small entities.
At this time, we lack the available
economic information necessary to
provide an adequate factual basis for the
required RFA finding. Therefore, we
defer the RFA finding until completion
of the draft economic analysis. This
draft economic analysis will provide the
required factual basis for the RFA
finding. Upon completion of the draft
economic analysis, we will announce
availability of the draft economic
analysis of the proposed designation in
the Federal Register and reopen the
public comment period for the proposed
designation. We will include with this
announcement, as appropriate, an initial
regulatory flexibility analysis or a
certification that the rule will not have
a significant economic impact on a
substantial number of small entities
accompanied by the factual basis for
that determination.
Land use sectors that could be
affected by this proposed rule include:
BLM land managers, CPSD State Park
land managers, and ORV users that may

be or are utilizing the proposed critical
habitat unit.
We have concluded that deferring the
RFA finding until completion of the
draft economic analysis is necessary to
meet the purposes and requirements of
the RFA. Deferring the RFA finding in
this manner will ensure that we make a
sufficiently informed determination
based on adequate economic
information and provide the necessary
opportunity for public comment.

Energy Supply, Distribution, or Use—
Executive Order 13211
Executive Order 13211 (Actions
Concerning Regulations That
Significantly Affect Energy Supply,
Distribution, or Use) requires agencies
to prepare Statements of Energy Effects
when undertaking certain actions. We
do not expect the designation of this
proposed critical habitat to significantly
affect energy supplies, distribution, or
use as there is no energy supply or
distribution infrastructure near the
proposed critical habitat. Therefore, this
action is not a significant energy action,
and no Statement of Energy Effects is
required. However, we will further
evaluate this issue as we conduct our
economic analysis, and review and
revise this assessment as warranted.
Unfunded Mandates Reform Act (2
U.S.C. 1501 et seq.)
In accordance with the Unfunded
Mandates Reform Act (2 U.S.C. 1501 et
seq.), we make the following findings:
(1) This rule will not produce a
Federal mandate. In general, a Federal
mandate is a provision in legislation,
statute, or regulation that would impose
an enforceable duty upon State, local, or
Tribal governments, or the private
sector, and includes both ‘‘Federal
intergovernmental mandates’’ and
‘‘Federal private sector mandates.’’
These terms are defined in 2 U.S.C.
658(5)–(7). ‘‘Federal intergovernmental
mandate’’ includes a regulation that
‘‘would impose an enforceable duty
upon State, local, or tribal governments’’
with two exceptions. It excludes ‘‘a
condition of Federal assistance.’’ It also
excludes ‘‘a duty arising from
participation in a voluntary Federal
program,’’ unless the regulation ‘‘relates
to a then-existing Federal program
under which $500,000,000 or more is
provided annually to State, local, and
tribal governments under entitlement
authority,’’ if the provision would
‘‘increase the stringency of conditions of
assistance’’ or ‘‘place caps upon, or
otherwise decrease, the Federal
Government’s responsibility to provide
funding,’’ and the State, local, or Tribal
governments ‘‘lack authority’’ to adjust
VerDate Mar<15>2010
15:28 Oct 01, 2012
Jkt 229001
accordingly. At the time of enactment,
these entitlement programs were:
Medicaid; Aid to Families with
Dependent Children work programs;
Child Nutrition; Food Stamps; Social
Services Block Grants; Vocational
Rehabilitation State Grants; Foster Care,
Adoption Assistance, and Independent
Living; Family Support Welfare
Services; and Child Support
Enforcement. ‘‘Federal private sector
mandate’’ includes a regulation that
‘‘would impose an enforceable duty
upon the private sector, except (i) a
condition of Federal assistance or (ii) a
duty arising from participation in a
voluntary Federal program.’’
The designation of critical habitat
does not impose a legally binding duty
on non-Federal Government entities or
private parties. Under the Act, the only
regulatory effect is that Federal agencies
must ensure that their actions do not
destroy or adversely modify critical
habitat under section 7. While nonFederal entities that receive Federal
funding, assistance, or permits, or that
otherwise require approval or
authorization from a Federal agency for
an action, may be indirectly impacted
by the designation of critical habitat, the
legally binding duty to avoid
destruction or adverse modification of
critical habitat rests squarely on the
Federal agency. Furthermore, to the
extent that non-Federal entities are
indirectly impacted because they
receive Federal assistance or participate
in a voluntary Federal aid program, the
Unfunded Mandates Reform Act would
not apply, nor would critical habitat
shift the costs of the large entitlement
programs listed above onto State
governments.
(2) We do not believe that this rule
will significantly or uniquely affect
small governments because the lands
being proposed for critical habitat
designation are owned by the State of
Utah, and the BLM. None of these
government entities fit the definition of
‘‘small governmental jurisdiction.’’
Therefore, a Small Government Agency
Plan is not required. However, we will
further evaluate this issue as we
conduct our economic analysis, and
review and revise this assessment as
warranted.
Takings—Executive Order 12630
In accordance with Executive Order
12630 (Government Actions and
Interference with Constitutionally
Protected Private Property Rights), we
have analyzed the potential takings
implications of designating critical
habitat for CPSD tiger beetle in a takings
implications assessment. Critical habitat
designation does not affect landowner
PO 00000
Frm 00026
Fmt 4701
Sfmt 4702
actions that do not require Federal
funding or permits, nor does it preclude
development of habitat conservation
programs or issuance of incidental take
permits to permit actions that do require
Federal funding or permits to go
forward. The takings implications
assessment concludes that this
designation of critical habitat for CPSD
tiger beetle does not pose significant
takings implications for lands within or
affected by the designation.
Federalism—Executive Order 13132
In accordance with Executive Order
13132 (Federalism), this proposed rule
does not have significant Federalism
effects. A Federalism assessment is not
required. In keeping with Department of
the Interior and Department of
Commerce policy, we requested
information from, and coordinated
development of this proposed critical
habitat designation with, appropriate
State resource agencies in Utah. The
designation of critical habitat in areas
currently occupied by CPSD tiger beetle
may impose nominal additional
regulatory restrictions to those currently
in place and, therefore, may have little
incremental impact on State and local
governments and their activities. The
designation may have some benefit to
these governments because the areas
that contain the physical or biological
features essential to the conservation of
the species are more clearly defined,
and the elements of the features of the
habitat necessary to the conservation of
the species are specifically identified.
This information does not alter where
and what federally sponsored activities
may occur. However, it may assist local
governments in long-range planning
(rather than having them wait for caseby-case section 7 consultations to
occur).
Where State and local governments
require approval or authorization from a
Federal agency for actions that may
affect critical habitat, consultation
under section 7(a)(2) would be required.
While non-Federal entities that receive
Federal funding, assistance, or permits,
or that otherwise require approval or
authorization from a Federal agency for
an action, may be indirectly impacted
by the designation of critical habitat, the
legally binding duty to avoid
destruction or adverse modification of
critical habitat rests squarely on the
Federal agency.
Civil Justice Reform—Executive Order
12988
In accordance with Executive Order
12988 (Civil Justice Reform), the Office
of the Solicitor has determined that the
rule does not unduly burden the judicial
E:\FR\FM\02OCP3.SGM
02OCP3
Federal Register / Vol. 77, No. 191 / Tuesday, October 2, 2012 / Proposed Rules
system and that it meets the
requirements of sections 3(a) and 3(b)(2)
of the Order. We have proposed
designating critical habitat in
accordance with the provisions of the
Act. This proposed rule uses standard
property descriptions and identifies the
elements of physical or biological
features essential to the conservation of
the CPSD tiger beetle within the
designated areas to assist the public in
understanding the habitat needs of the
species.
Paperwork Reduction Act of 1995 (44
U.S.C. 3501 et seq.)
This rule does not contain any new
collections of information that require
approval by OMB under the Paperwork
Reduction Act of 1995 (44 U.S.C. 3501
et seq.). This rule will not impose
recordkeeping or reporting requirements
on State or local governments,
individuals, businesses, or
organizations. An agency may not
conduct or sponsor, and a person is not
required to respond to, a collection of
information unless it displays a
currently valid OMB control number.
National Environmental Policy Act (42
U.S.C. 4321 et seq.)
wreier-aviles on DSK5TPTVN1PROD with PROPOSALS3
It is our position that, outside the
jurisdiction of the U.S. Court of Appeals
for the Tenth Circuit, we do not need to
prepare environmental analyses
pursuant to the NEPA (42 U.S.C. 4321
et seq.) in connection with designating
critical habitat under the Act. We
published a notice outlining our reasons
for this determination in the Federal
Register on October 25, 1983 (48 FR
49244). This position was upheld by the
U.S. Court of Appeals for the Ninth
Circuit (Douglas County v. Babbitt, 48
F.3d 1495 (9th Cir. 1995), cert. denied
516 U.S. 1042 (1996)).
However, when the range of the
species includes States within the Tenth
Circuit, such as that of CPSD tiger
beetle, under the Tenth Circuit ruling in
Catron County Board of Commissioners
v. U.S. Fish and Wildlife Service, 75
F.3d 1429 (10th Cir. 1996), we will

environmental assessment for this
proposal when it is finished.
Government-to-Government
Relationship With Tribes
In accordance with the President’s
memorandum of April 29, 1994
(Government-to-Government Relations
with Native American Tribal
Governments; 59 FR 22951), Executive
Order 13175 (Consultation and
Coordination With Indian Tribal
Governments), and the Department of
the Interior’s manual at 512 DM 2, we
readily acknowledge our responsibility
to communicate meaningfully with
recognized Federal Tribes on a
government-to-government basis. In
accordance with Secretarial Order 3206
of June 5, 1997 (American Indian Tribal
Rights, Federal-Tribal Trust
Responsibilities, and the Act), we
readily acknowledge our responsibilities
to work directly with Tribes in
developing programs for healthy
ecosystems, to acknowledge that Tribal
lands are not subject to the same
controls as Federal public lands, to
remain sensitive to Indian culture, and
to make information available to Tribes.
We determined that there are no
Tribal lands that were occupied by
CPSD tiger beetle at the time of listing
that contain the features essential for
conservation of the species, and no
Tribal lands unoccupied by the CPSD
tiger beetle that are essential for the
conservation of the species. Therefore,
we are not proposing to designate
critical habitat for CPSD tiger beetle on
Tribal lands.
Clarity of the Rule
We are required by Executive Orders
12866 and 12988 and by the
Presidential Memorandum of June 1,
1998, to write all rules in plain
language. This means that each rule we
publish must:
(1) Be logically organized;
(2) Use the active voice to address
readers directly;
(3) Use clear language rather than
jargon;
(4) Be divided into short sections and
sentences; and

(5) Use lists and tables wherever
possible.
If you feel that we have not met these
requirements, send us comments by one
of the methods listed in the ADDRESSES
section. To better help us revise the
rule, your comments should be as
specific as possible. For example, you
should tell us the numbers of the

SUPPLEMENTARY INFORMATION: This document consists of: (1) A proposed
rule to list the Coral Pink Sand Dunes (CPSD) tiger beetle as
threatened; and (2) a proposed critical habitat designation for the
CPSD tiger beetle.
Executive Summary
Why we need to publish a rule. Under the Act, if a species is
determined to be an endangered or threatened species throughout all or
a significant portion of its range, we are required to promptly publish
a proposed rule in the Federal Register and make a determination on our
proposal within one year. Critical habitat shall be designated, to the
maximum extent prudent and determinable, for any species determined to
be an endangered or threatened species under the Act. Listing a species
as an endangered or threatened species and designations and revisions
of critical habitat can only be completed in a rule making process.
What This Rule Will Do
We are proposing to list the CPSD tiger beetle as a
threatened species.
We also are proposing to designate 921 hectares (2,276
acres) of the Coral Pink Sand Dunes (CPSD) Geologic Feature in Kane
County as critical habitat.
The basis for our action. Under the Act, we can determine that a
species is an endangered or threatened species based on any of five
factors: (A) The present or threatened destruction, modification, or
curtailment of its habitat or range; (B) Overutilization for
commercial, recreational, scientific, or educational purposes; (C)
Disease or predation; (D) The inadequacy of existing regulatory
mechanisms; or (E) Other natural or manmade factors affecting its
continued existence.
We propose to list the CPSD tiger beetle as a threatened species
because of the following threats:
Habitat loss and degradation caused by off-road vehicle
use.
Small population effects, such as vulnerability to random
chance events.
Other natural or manmade factors, including climate change
and drought.
Cumulative interaction of individual factors such as off-
road vehicle use, climate change, and drought.
We have also determined that existing regulatory mechanisms are not
adequately addressing the threats to the species.
Under the Act, any species that is determined to be a threatened or
endangered species shall, to the maximum extent prudent and
determinable, have habitat designated that is considered to be critical
habitat. Section 4(b)(2) of the Endangered Species Act states that the
Secretary shall designate critical habitat on the basis of the best
available scientific data after taking into consideration the economic
impact, national security impact, and any other relevant impact of
specifying any particular area as critical habitat.
We propose to designate a 921-hectare (2,276-acre) area as critical
habitat for the CPSD tiger beetle. The critical habitat area we propose
in this rule constitutes our current best assessment of the specific
areas that meet the definition of critical habitat for the CPSD tiger
beetle.
We are preparing an economic analysis of the proposed designation
of critical habitat. In order to consider economic impacts, we are
preparing an analysis of the potential economic impacts of the proposed
critical habitat designations. We will use the information from the
draft economic analysis to inform the development of the final
designation of critical habitat for this species.
We are preparing an environmental assessment of the proposed
designation of critical habitat. Based on a relevant court decision in
the Tenth Circuit, we shall evaluate the potential environmental
impacts of a designation of critical habitat for any species whose
range overlaps the geographic area governed by the Federal Tenth
Circuit Court under the National Environmental Policy Act (NEPA). We
will use the results of the draft environmental assessment to inform
the development of our final designation of critical habitat.
[[Page 60209]]
We will seek peer review. We are seeking the expert opinions of
appropriate and independent specialists regarding this proposed rule to
ensure that our decisions are based on scientifically sound data,
assumptions, and analysis. We have invited these peer reviewers to
comment during the proposed rule's public comment period. We will
consider all comments and information received during the comment
period in our preparation of the final determinations. Accordingly, the
final decisions may differ from this proposal.
Information Requested
We intend that any final action resulting from this proposed rule
will be based on the best scientific and commercial data available and
be as accurate and as effective as possible. Therefore, we request
comments or information from the public, other concerned governmental
agencies, Native American Tribes, the scientific community, industry,
or any other interested parties concerning this proposed rule. We
particularly seek comments concerning:
(1) The species' biology, range, and population trends, including:
(a) Habitat requirements for feeding, breeding, and sheltering;
(b) Genetics and taxonomy;
(c) Historical and current range including distribution patterns;
(d) Historical and current population levels, and current and
projected trends; and
(e) Past and ongoing conservation measures for the species, its
habitat or both.
(2) The factors that are the basis for making a listing
determination for a species under section 4(a) of the Act (16 U.S.C.
1531 et seq.), which are:
(a) The present or threatened destruction, modification, or
curtailment of its habitat or range;
(b) Overutilization for commercial, recreational, scientific, or
educational purposes;
(c) Disease or predation;
(d) The inadequacy of existing regulatory mechanisms; or
(e) Other natural or manmade factors affecting its continued
existence.
(3) Biological, commercial, or other relevant data concerning any
threats (or lack thereof) to this species and existing regulations that
may be addressing those threats.
(4) Additional information concerning the historical and current
status, range, distribution, and population size of this species,
including the locations of any additional populations of this species.
(5) The reasons why we should or should not designate specific
areas as ``critical habitat'' under section 4 of the Act (16 U.S.C.
1531 et seq.) including whether the degree of threats would be expected
to increase due to the designation, and whether that increase in threat
outweighs the benefit of designation such that the designation of
critical habitat may not be prudent.
(6) Specific information on our proposed critical habitat
designation:
(a) The amount and distribution of CPSD tiger beetle habitat;
(b) What may constitute ``physical or biological features essential
to the conservation of the species,'' within the geographical range
currently occupied by the species;
(c) Where these features are currently found;
(d) Whether any of these features may require special management
considerations or protection;
(e) What areas, that were occupied at the time of listing (or are
currently occupied) and that contain features essential to the
conservation of the species, should be included in the designation and
why;
(f) What areas not occupied at the time of listing are essential
for the conservation of the species and why.
(7) Land use designations and current or planned activities in the
areas occupied by the species or proposed to be designated as critical
habitat, and possible impacts of these activities on this species and
proposed critical habitat.
(8) Information on the projected and reasonably likely impacts of
climate change on the CPSD tiger beetle and proposed critical habitat.
(9) Any foreseeable economic, national security, or other relevant
impacts that may result from designating any area that may be included
in the final designation. We are particularly interested in any impacts
on small entities, and the benefits of including or excluding areas
from the proposed designation that are subject to these impacts.
(10) Whether our approach to designating critical habitat could be
improved or modified in any way to provide for greater public
participation and understanding, or to assist us in accommodating
public concerns and comments.
(11) The likelihood of adverse social reactions to the designation
of critical habitat and how the consequences of such reactions, if
likely to occur, would relate to the conservation and regulatory
benefits of the proposed critical habitat designation.
Please include sufficient information with your submission (such as
scientific journal articles or other publications) to allow us to
verify any scientific or commercial information you include.
Please note that submissions merely stating support for or
opposition to the action under consideration without providing
supporting information, although noted, will not be considered in
making a determination, as section 4(b)(1)(A) of the Act directs that
determinations as to whether any species is an endangered or threatened
species must be made ``solely on the basis of the best scientific and
commercial data available.''
You may submit your comments and materials concerning this proposed
rule by one of the methods listed in the ADDRESSES section.
If you submit information via https://www.regulations.gov, your
entire submission--including any personal identifying information--will
be posted on the Web site. If your submission is made via a hardcopy
that includes personal identifying information, you may request at the
top of your document that we withhold this information from public
review. However, we cannot guarantee that we will be able to do so. We
will post all hardcopy submissions on https://www.regulations.gov.
Please include sufficient information with your comments to allow us to
verify any scientific or commercial information you include.
Comments and materials we receive, as well as supporting
documentation we used in preparing this proposed rule, will be
available for public inspection on https://www.regulations.gov, or by
appointment, during normal business hours, at the U.S. Fish and
Wildlife Service, Utah Field Office (see FOR FURTHER INFORMATION
CONTACT).
Previous Federal Actions
In 1984, we published our Invertebrate Notice of Review classifying
the CPSD tiger beetle as a Category 2 species (49 FR 21664, May 22,
1984). Category 2 status included those taxa for which information in
the Service's possession indicated that a proposed rule was possibly
appropriate, but for which sufficient data on biological vulnerability
and threats were not available to support a proposed listing rule. In
1994, the Southern Utah Wilderness Alliance petitioned us to list the
CPSD tiger beetle as an endangered species and to designate critical
habitat. In our 90-day petition finding (59 FR 47293, September 15,
1994), we indicated the petition presented substantial information in
support of listing, and later that year we changed the CPSD tiger
beetle's status from Category 2 to Category 1 (59 FR 58982, November
15, 1994). Category 1 status
[[Page 60210]]
included those taxa for which the Service had sufficient information on
biological vulnerability and threats to support proposals to list them
as endangered or threatened species. On December 5, 1996 (61 FR 64481),
we published our decision to discontinue candidate categories and to
restrict candidate status to those taxa for which we have sufficient
information to support issuance of a proposed rule. As a result, the
CPSD tiger beetle remained a candidate species (62 FR 49398, September
19, 1997).
In 1997, the Service, Bureau of Land Management (BLM), Utah
Department of Natural Resources (UDNR), and Kane County signed a
Candidate Conservation Agreement (CCA) and formed a conservation
committee with the dual goals of protecting CPSD tiger beetle habitat
and balancing the needs of this rare species with off-road vehicle
(ORV) use in the area (Conservation Committee 1997, pp. 4-5). These
agencies renewed the CCA in 2009 (Conservation Committee 2009, entire).
Coordination under the CCA resulted in the establishment of two
Conservation Areas that protect the CPSD tiger beetle from ORV use--
Conservation Areas A and B (see Habitat and Factor A for more
information on the Conservation Areas).
In our 2010 Candidate Notice of Review, we identified the CPSD
tiger beetle as a species for which listing as an endangered or
threatened species was warranted (with a listing priority number of 2)
but precluded by our work on higher priority listing actions (75 FR
69222, November 10, 2010). In the 2011 Candidate Notice of Review, we
announced that we were not updating our assessment for this species,
because we received funding to develop this proposed listing rule (76
FR 66370, October 26, 2011).
Background
Taxonomy and Species Description
The CPSD tiger beetle is a member of the family Cicindelidae and
genus Cicindela. There are 109 species of tiger beetles in the genus
Cicindela in the United States and Canada (Pearson et al. 2006, p. 4).
The CPSD tiger beetle occurs only at the CPSD geologic feature in
southern Utah and is separated from its closest related subspecies, C.
theatina, by over 600 kilometers (km) (378 miles (mi)) (Rumpp 1961, p.
182). It shares the typical characteristics of other members of the
maritima group (a group of closely related species of sand dune tiger
beetles) and is most similar in morphology to other subspecies of
Cicindela limbata (no common name). It was originally described as C.
limbata albissima (Rumpp 1961, p. 181). However, more recent genetic
analysis revealed that the CPSD tiger beetle is different from all
other members in the maritima group; consequently, we now consider it a
distinct species, CPSD tiger beetle (Morgan et al. 2000, p. 1111). This
is the accepted taxonomic classification (Pearson et al. 2006, p. 77).
CPSD tiger beetle adults are 11 to 15 millimeters (0.4 to 0.6
inches (in)) in size and have striking coloration. The large wing cases
(known as elytra) are predominantly white except for a thin reddish
band that runs down the length of the center. Much of the body and legs
are covered in white hairs. The upper thorax (middle region) has a
metallic sheen, and the eyes are particularly large (Pearson et al.
2006, p. 77).
Habitat
Tiger beetle species occur in many different habitats, including
riparian habitats, beaches, dunes, woodlands, grasslands, and other
open areas (Pearson et al. 2006, p. 177). Most tiger beetle species are
habitat-specific and consequently are useful as indicators of habitat
quality (Knisley and Hill 1992, p. 140). The CPSD tiger beetle, like
its close relatives from the Great Sand Dunes of Colorado (Cicindela
theatina) and the St. Anthony Dunes of Idaho (C. arenicola), is
restricted to sand dune habitat.
The species' current range extends along the CPSD geologic feature.
The CPSD is a geologic feature named for the deep pink color of its
sand dunes (Ford et al. 2010, p. 380). The CPSD are located 5 km (3.1
mi) north of the Utah-Arizona state line and 43 km (27 mi) west of
Kanab, Utah (see Figure 1 below in Population Distribution). The CPSD
are about 13 km (8 mi) long, averaging 1.1 km (0.7 mi) in width, and
1,416 ha (3,500 ac) in surface area.
The CPSD consist of a series of high, mostly barren, dry dune
ridges separated by lower, moister, and more vegetated interdunal
swales (low places between sand dune crests) (Romey and Knisley 2002,
p. 170). Wind action, primarily blowing from south to north, created
and continues to shape the CPSD, utilizing sand from nearby eroding
Navajo sandstone (Doelling et al. 1989, p. 3). Wind velocity decreases
as it moves across the sand dunes (from south to north), resulting in a
dynamic and less vegetated south CPSD area that transitions to a less
dynamic, more heavily vegetated, higher elevation northern CPSD area
(Ford et al. 2010, pp. 387-392).
The CPSD are in a semiarid climatic zone (Ford et al. 2010, p.
381). The nearest weather station, in Kanab, has a mean annual
temperature of 12.4 [deg]Celsius ([deg]C) (54.4[emsp14][deg]Fahrenheit
([deg]F)) and mean annual precipitation of 33.8 centimeters (cm) (13.3
in) (Ford et al. 2010, p. 381). The northern 607 ha (1,500 ac) of CPSD
is Federal land managed by the BLM. The southern 809 ha (2,000 ac) of
the CPSD is within Utah's CPSD State Park.
Adult CPSD tiger beetles use most of the dune areas from the swales
to the upper dune slopes. Larval CPSD tiger beetles are more restricted
to vegetated swale areas (Knisley and Hill 2001, p. 386), where the
vegetation supports the larval prey base of flies, ants, and other prey
(Conservation Team 2009, p. 14). Larval CPSD tiger beetle habitat is
typically dominated by the leguminous plants Sophora stenophylla
(silvery sophora) and Psoralidium lanceolatum (dune scurfpea), and
several grasses, including Sporobolus cryptandrus (sand dropseed) and
Achnatherum hymenoides (Indian ricegrass). Larvae also are closely
associated with a federally threatened plant species, Asclepius welshii
(Welsh's milkvetch) (Knisley and Hill 2001, p. 385) for which the
entire CPSD area is designated critical habitat (52 FR 41435, October
28, 1987).
Rainfall and associated soil moisture is a critical factor for CPSD
tiger beetles (Knisley and Juliano 1988, entire) and is likely the most
important natural environmental factor affecting population dynamics of
the species. Rainfall and the associated increase in soil moisture have
a positive effect on CPSD tiger beetle oviposition (egg depositing) and
survivorship (Knisley and Hill 2001, p. 391). The areas in the dune
field with the highest level of soil moisture and where soil moisture
is closer to the surface contain the highest densities of CPSD tiger
beetle larvae (Knisley and Gowan 2011, p. 22), indicating that both
proximity to moisture and overall soil moisture are important to the
CPSD tiger beetle's life cycle. Experimental supplemental watering has
resulted in significantly more adults and larvae, more oviposition
events, increased larval survival, and faster larval development
compared to unwatered control plots (Knisley and Gowan 2011, pp. 18-
22).
Population Distribution
The CPSD tiger beetle (Cincindela albissima) occurs sporadically
throughout the CPSD geologic feature, but only consistently exists in
two populations--central and northern--which are separated by 4.8 km (3
mi)
[[Page 60211]]
(Figure 1; Knisley 2012, pers. comm.). The two populations occupy a
total area approximately 202 ha (500 ac) in size (Morgan et al. 2000,
p. 1109).
The central population is the largest and is self-sustaining, but
at relatively low numbers (see Population Size and Dynamics, below).
The northern population is not considered self-sustaining and comprises
only a small number of adults and larvae (Knisley 2001, p. 9). The
northern population likely persists because of adults dispersing from
the central population (Knisley and Gowan 2011, p. 9).
Low densities of adult CPSD tiger beetles also occur in the dune
area between the central and northern populations (Figure 1; Hill and
Knisley 1993, p. 9; Knisley 2012, pers. comm.), and suitable swale
habitat likely exists in this area. This area has not been extensively
surveyed in the past 20 years, and observations of the species in this
area are from opportunistic and inconsistent surveys. Because the
northern population likely is dependent upon adults dispersing from the
central population (Knisley and Gowan 2011, p. 9), the 4.8-km (3-mi)
long area of dune between the two populations is likely an important
dispersal corridor for the species (see Adult Dispersal below).
BILLING CODE P
[[Page 60212]]
[GRAPHIC] [TIFF OMITTED] TP02OC12.003
BILLING CODE C
As previously mentioned (see Previous Federal Actions), an
interagency CCA established Conservation Areas A and B to protect the
CPSD tiger beetles from ORV use (see Factor A, The Present or
Threatened Destruction, Modification, or Curtailment of its Habitat or
Range for more information). These Conservation Areas generally overlap
the central and northern populations of CPSD tiger beetles (see Figure
1). However, the central population does not occupy the entirety of
Conservation Area A, and also extends outside of it. We do not have
occupied swale information for the northern population, so for purposes
of this rule, we will assume that the northern population, during most
years, occupies some swale habitat in an area that overlaps
Conservation Area B entirely. Conservation Area A is 84 ha (207 ac) in
size, and Conservation Area B is 150
[[Page 60213]]
ha (370 ac) in size (Knisley and Gowan 2011, pp. 7, 9).
We do not have comprehensive analysis or occupancy modeling that
predicts the habitat preferences of the CPSD tiger beetle. However, a
preliminary habitat assessment indicated that the beetle exists where
there is abundant prey and larvae, large swale areas capable of
supporting the appropriate vegetation, swale sediment characteristics
appropriate for vegetation and larval burrows, dune migration
characteristics that permit vegetation to develop and persist within
dune swales, proper sediment supply, and a proper wind regime (Fenster
et al. 2012, pp. 2-4). The presence of CPSD tiger beetles in the
northern and eastern portions of Conservation Area A, to the east and
outside of Conservation Area A (despite the lack of protection from ORV
traffic), and in limited swales in Conservation Area B, indicate that
many or all of these habitat conditions occur in these areas. See the
Factor A section, and other subsections in Background for more
information on CPSD tiger beetle preferred habitat characteristics.
The same preliminary habitat assessment indicated that CPSD tiger
beetles do not exist where there is a lack of prey, small swale areas
incapable of supporting the appropriate vegetation, swale sediment
characteristics not conducive for vegetation nor suitable for larval
burrows, dune migration characteristics that do not permit vegetation
to develop and persist within dune swales, low sediment supply, and
wind velocities that are too high or too low to maintain proper dune
form and vegetation densities (Fenster et al. 2012, pp. 4-5). The
general absence of CPSD tiger beetles in the south-central and
southeastern portions of Conservation Area A and the general area south
of Conservation Area A, indicate that many of these habitat conditions
occur in these areas. See the Factor A section, and other subsections
in Background for more information on CPSD tiger beetle preferred
habitat characteristics.
Life History
Similar to other tiger beetles, the CPSD tiger beetle goes through
several developmental stages. These include an egg, three larval stages
(known as ``instars,'' with each instar separated by molting), pupa,
and adult (Knisley and Shultz 1997, p. 13). First instar larvae appear
in late spring after hatching from eggs that were oviposited in sand
the previous late summer or fall (Hill and Knisley 1997, p. 2). The
first instar larvae dig small vertical burrows from the sand surface
down 6 to 9 cm (2.4 to 3.5 in.) into the sand substrate (Conservation
Committee 2009, p. 14). After several weeks of feeding at the surface,
the first instar larva plugs its burrow opening, sheds its skin
(molts), and becomes a larger second instar larva (Conservation
Committee 1997, p. 2). The second instar stage lasts several months
(again emerging from its burrow and feeding at the surface for a brief
period) before developing into a third instar, with most reaching this
stage by mid- to late summer (Conservation Committee 1997, p. 2).
Larvae continue as second or third instars into fall, and then
hibernate in burrows during the winter (Conservation Committee 1997, p.
3). The third instar stage can take 9 months to over a year to reach
full development (Conservation Committee 1997, p. 3). After the third
instar is fully developed, the CPSD tiger beetle plugs its burrow
opening and transforms into a pupa (Pearson and Vogler 2001, p. 34).
During the pupal period (stage between third instar and adult
emergence), the beetle undergoes a metamorphosis where many of the
adult physical structures develop (i.e., wings and flight muscles)
(Pearson and Vogler 2001, p. 34). Adults emerge soon after this
metamorphosis. The CPSD tiger beetle completes its entire life cycle
from egg to adult reproduction to death within 2 or 3 years (Hill and
Knisley 1997, p. 3).
Adult Behavior and Ecology
Adults are active on sunny days along the dunes and swale edges.
The majority of recently metamorphosed adult CPSD tiger beetles emerge
from their burrows in late March to early April, reach peak abundance
by May, begin declining in June, and die by August (Knisley and Hill
2001, p. 387). A small proportion of a second adult cohort emerges in
early September and remains active into October before digging
overwintering burrows (Knisley and Hill 2001, pp. 387-388).
Adult tiger beetles are active predators, attacking and eating prey
with their large and powerful mandibles (mouthparts). They can run or
fly rapidly over the sand surface to capture or scavenge for prey
arthropods. Adults feed primarily on ants, flies, and other small
arthropods (Knisley and Hill 1993, p. 13).
CPSD tiger beetle behavior and distribution, like other tiger
beetles, is largely determined by their thermoregulation needs. Adult
tiger beetles dedicate up to 56 percent of their daily activity towards
behavior that controls their internal body temperature (Pearson and
Vogler 2001, p. 135). These behaviors include basking (positioning the
body to maximize exposure to solar radiation); seeking out wet, cool
substrate or shade; and burrowing (Pearson and Vogler 2001, p. 136).
Tiger beetles with low body temperatures are sluggish; tiger beetles
require a high body temperature for maximal predatory activity (Pearson
and Vogler 2001, p. 131). Thus, the numbers of adult CPSD tiger beetles
observed on rainy or cool, cloudy days are very low (Knisley and Hill
2001, p. 388). Tiger beetles maintain body temperatures near their
lethal limits of 47 to 49 [deg]C (116 to 120 [deg]F) (Pearson and
Vogler 2001, p. 131), so heat refuge is important (Shutlz and Hadley
1987, p. 363). During peak spring and fall activity, when it is sunny,
adult CPSD tiger beetles are usually active early (9 a.m.-2 p.m.) and
again in late afternoon (4 p.m.-7 p.m.) (Knisley and Hill 1993, pp. 13-
14). They dig and reside in burrows to avoid unfavorable weather
conditions such as hot mid-afternoons or cool or rainy daytime
conditions (Knisley and Hill 1993, p. 14). Shade provided by vegetative
cover is important for CPSD tiger beetle thermoregulation during warm
periods (Knisley 2012, pers. comm.).
Adult Dispersal
Dispersal is the movement of individuals from one habitat area to
another. The ability to disperse is often important to tiger beetle
species because many species inhabit areas such as sand dunes or
riverbanks that are prone to disturbance and physical change (Pearson
and Vogler 2001, pp. 130-142) (see Factor E (Sand Dune Movement)
below). We do not have information on the dispersal habits of the CPSD
tiger beetle, so we evaluated information for surrogate species that
occupy unstable habitats similar to those of the CPSD geologic
formation. The Maricopa tiger beetle, Cicindela oregona maricopa, is an
example of a species that persists in an unstable environment because
of dispersal. The Maricopa tiger beetle inhabits moist sandy habitat on
the banks of small streams and creeks (Pearson and Vogler 2001, p.
141). Flash flooding periodically scours away this sandy habitat and
most of the existing population (Pearson and Vogler 2001, p. 141).
These floods redistribute the scoured sand elsewhere, and surviving
adult tiger beetles quickly disperse and colonize the newly available
habitat (Pearson and Vogler 2001, p. 141). Similarly for the CPSD tiger
beetle, the CPSD geologic formation is continually changing as winds
redistribute the sands, both creating and destroying swale habitat and
dispersal habitat within and between Conservation Areas A and B (see
Factor E Sand Dune Movement below).
[[Page 60214]]
Often, tiger beetle populations depend upon dispersal among
separated populations for the survival of individual populations and
the species (Knisley et al. 2005, p. 557). The extirpation of at least
one population of the Northeastern Beach tiger beetle, Cicindela
dorsalis dorsalis, (federally listed as a threatened species) is
partially attributed to the lack of nearby populations and associated
dispersal habitats (Knisley et al. 2005, p. 557). Similarly, in CPSD
the northern population of the CPSD tiger beetle likely persists
because of dispersal from the central population, across the CPSD
(Knisley and Gowan 2011, p. 9). In like fashion, the resilience of the
central population would be greatly increased if the northern
population became self-sustaining and could contribute to the central
population by dispersing across the CPSD.
Larval Behavior and Ecology
Larval CPSD tiger beetles are ambush predators that wait at their
burrow mouth to capture small arthropod prey when it passes nearby. The
daily period of activity is highly variable and influenced by
temperature, moisture levels, and season (Knisley and Hill 2001, p.
388; Knisley and Gowan 2008, p. 20). Larvae can be active much of the
day during cool or cloudy spring and fall days, except during high wind
periods (Conservation Committee 2009, p. 14). Maximal activity occurs
in early mornings before the soil becomes dry and warm from the sun and
again in late afternoon and evening after the soil has cooled
(Conservation Committee 2009, p. 14).
Adult females determine the larval microhabitat by their selection
of an oviposition site (Knisley and Gowan 2011, p. 6). Recently hatched
larvae construct burrows in the sand at the site of oviposition and
subsequently pass through three larval stages before pupating and then
emerging to the adult form (Conservation Committee 2009, p. 14). Most
larvae occur within the swale bottoms and up the lower slopes of the
dunes, particularly where the soil or subsoil is moist most of the time
(Hill and Knisley 1996, p. 11; Knisley and Gowan 2011, p. 22). The
swale vegetation supports the larval prey base of ants, flies, and
other prey (Conservation Committee 2009, p. 14). Larvae most often
remain in the same burrow throughout their development and only rarely
move outside of their burrow to dig a new burrow in a more favorable
location (Knisley and Hill 1996, p. 11).
Population Size and Dynamics
Substantial year-to-year population variation is typical of many
desert arthropods that are greatly affected by climatic factors such as
rainfall (Knisley and Hill 2001, p. 391). Adult abundance in any year
is a result of many interacting factors that affect recruitment of the
cohort oviposited 2 or 3 years previous (because of a 2- or 3-year life
cycle), and also the survivorship of the developmental stages of that
year's cohort (Knisley 2001, p. 10).
The central and northern populations were monitored for the last 20
and 14 years (respectively) to yield a yearly adult CPSD tiger beetle
population size estimate (monitoring did not take place outside of
these populations) (Figure 2). The adult population size estimate is
based solely on data collected from the central population from 1992 to
1997, and after 1997 the adult population size estimate is based on
both populations. Population numbers fluctuated greatly over this time,
ranging from a low of 558 in 2005 to a high of 2,944 in 2002 (Figure
2). The total adult population size estimate in 2011 was 1,116 (Knisley
and Gowan 2011, p. 7). Population monitoring results indicate a low,
yet stable to increasing population size since 2003 that contrasts with
highly variable population estimates in previous periods (Knisley and
Gowan 2011, pp. 7-8; Figure 2); however, the overall trend since 1992
suggests that the population is in decline.

Population Viability Analysis
Population viability analysis (PVA) is a way to predict the
population dynamics of a species under various management alternatives
(Brook et al. 2000, p. 385). PVAs generate future predictions for a
given species based upon past and present population, environmental
data, and selected management alternatives. Two PVAs are available for
the CPSD tiger beetle using the same methods, one from 1998 using adult
population counts from 1992 through 1998, and the other from 2008 using
adult counts from 1999 through 2008 (Knisley and Gowan 2009, pp. 17-
18).
Both PVAs only consider adult beetles from the Conservation Area A
population because Conservation Area B population numbers are extremely
low and the population is not considered self-sustaining (Knisley 2001,
p. 9). The PVA authors caution that the CPSD tiger beetle PVA should
only be used in a comparative way, to evaluate the effectiveness of
different management options (Knisley 2012, pers. comm.). They add that
the PVA predictions may not be quantitatively reliable for predicting
the absolute extinction probability of the species (Knisley 2012, pers.
comm.). For these reasons, we do not base our status determination for
this rulemaking on the PVA and instead use the PVA to evaluate existing
threats and potential conservation measures.
The PVA models do not directly account for current or future
threats and are entirely based on four demographic variables:
1. Starting population size;
2. Population growth rate (increase in population size year-to-
year);
3. Stochasticity (variation in yearly population growth rate); and
4. Carrying capacity (number of beetles that the habitat can
sustain).
The results of the two PVAs were generally similar in that growth
rate and stochasticity tend to control extinction probability. The most
recent PVA indicated a 32 percent chance of extinction and an 87
percent chance that the species would decline to 50 individuals within
the next 100 years (Knisley and Gowan 2009, p. 17). The first PVA was
based on only 7 years of data and predicted extremely variable
extinction probabilities (2 percent to 96 percent in 100 years);
however, the data were based on very rough estimates of population
growth rates (Knisley and Gowan 1999, pp. 5-6). Increases or decreases
in carrying capacity would have only a modest effect on the risk of
extinction, whereas decreasing stochasticity or increasing population
growth rate would greatly reduce the chance of extinction (Knisley and
Gowan 2009, p. 18). The authors of the PVA study recommended two
management actions to reduce the extinction probability. Their first
recommendation was to expand both Conservation Areas to include several
important swales that are believed to have suitable habitat, but are
being impacted by heavy ORV use, thus preventing successful
colonization and recruitment of CPSD tiger beetles (Knisley and Gowan
2009, p. 23). Expanding the size of both Conservation Areas would
likely increase the population growth rate because the protections
would improve overall habitat quality and lead to greater reproductive
success (e.g., Klok and de Roos 1998, pp. 205-206). Their second
suggestion was to translocate beetles and establish a self-sustaining
population in Conservation Area B (Knisley and Gowan 2009, p. 23),
although this would likely require improvements (e.g., vegetation
removal or watering during key development stages) to the existing
habitat (Knisley 2012, pers. comm.). The establishment of a self-
sustaining population in Conservation Area B, or elsewhere in the CPSD,
would change the dynamics of the PVA model by introducing the
possibility that a second self-sustaining population could ``rescue''
or recolonize the central population (and vice versa) in the event that
one of them were extirpated.
Summary of Factors Affecting the Species
Section 4 of the Act (16 U.S.C. 1533), and its implementing
regulations at 50 CFR part 424, set forth the procedures for adding
species to the Federal Lists of Endangered and Threatened Wildlife and
Plants. Under section 4(a)(1) of the Act, we may list a species based
on any of the following five factors: (A) The present or threatened
destruction, modification, or curtailment of its habitat or range; (B)
overutilization for commercial, recreational, scientific, or
educational purposes; (C) disease or predation; (D) the inadequacy of
existing regulatory mechanisms; and (E) other natural or manmade
factors affecting its continued existence. Listing actions may be
warranted based on any of the above threat factors, singly or in
combination. Each of these factors is discussed below.
Factor A. The Present or Threatened Destruction, Modification, or
Curtailment of Its Habitat or Range
Loss of habitat is the leading cause of species extinction (Pimm
and Raven 2000, p. 843). Insects are highly vulnerable to extinction
through habitat loss (McKinney 1997, pp. 501-507). ORV use
significantly impacts the CPSD tiger beetle's habitat, range, and the
beetle itself by directly killing beetles, damaging vegetation that
supports prey items, directly killing prey items, and reducing soil
moisture.
Nationwide, ORV use has drastically reduced or extirpated several
tiger beetle populations. For example, ORV use and pedestrian traffic
extirpated the Northeastern Beach tiger beetle, Cicindela dorsalis
dorsalis, in several localities (Knisley 2011, p. 45). Similarly,
within several years of the Assateague Island National Seashore
(Maryland, USA) opening for ORV use, the White Beach tiger beetle, C.
d. media, was extirpated from all but those areas where ORVs were
restricted (Knisley and Hill 1992, pp. 138-139). Additionally, ORV use
is responsible for eliminating tiger beetle populations in coastal
southern California (Hairy-necked tiger beetle, C. hirticollis
gravida), Oregon and Washington (Siuslaw hairy-necked tiger beetle, C.
h. siuslawensis), and Idaho (St. Anthony Dune tiger beetle, C.
arenicola) (Knisley 2011, p. 45).
As previously described (see Previous Federal Actions, Population
Distribution, and Figure 1), in 1997, the Service, BLM, Utah State
Parks and Recreation, and Kane County developed and signed a CCA and
formed a conservation committee to protect the CPSD tiger beetle within
an ORV-use area (Conservation Committee 1997). The CCA established
Conservation Areas A and B (see Figure 1 in Population Distribution
above) to protect CPSD tiger beetle habitat from ORV use: Conservation
Area A--84 ha (207 ac) are closed to ORV use within the CPSD State
Park; and Conservation Area B--150 ha (370 ac) are closed to ORV use on
BLM land.
Because we do not have survey information to determine the extent
of occupied swale habitat in the northern population (see Population
Distribution) and because the entirety of the northern population
occurs within Conservation Area B (protected from ORV use), the below
analysis is specific to the central population and Conservation Area A.
Conservation Area A protects 48 percent of the swale habitat occupied
by the CPSD tiger beetle in the central population, as well as 73 to 88
percent of CPSD tiger beetle adults and the vast majority of larvae
from ORV activities. ORV use still occurs in 52 percent of occupied
CPSD tiger beetle swale habitat in the central population (Figure
[[Page 60216]]
3, adapted from Knisley and Gowan 2009, p. 8).
Available information shows the effects of ORV use on current
population numbers. For example, swales adjacent to but outside of
Conservation Area A are similar in all apparent environmental
conditions to swales within Conservation Area A with the exception of
ORV impacts. However, CPSD tiger beetle abundance in ORV-impacted
occupied swales is consistently lower than adjacent protected occupied
swales, potentially because of ORV impacts (Figure 3).

[[Page 60217]]
BILLING CODE C
For example, one swale with ORV use had population counts of 60 or
more CPSD tiger beetles in most years (Knisley and Gowan 2011, p. 11).
Utah State Park staff, at the recommendation of the conservation
committee, protected this swale from ORV use in 2010 (Knisley and Gowan
2011, p. 11). The year following removal of ORV use, the tiger beetle
density on this swale more than doubled to 150 beetles, which also is
the highest number recorded for the swale (Knisley and Gowan 2011, p.
11). This action provides an example of how the conservation committee
has used adaptive management to benefit the CPSD tiger beetle and
demonstrates a rapid population response to removed ORV disturbance.
ORVs run over and thereby kill and injure CPSD tiger beetles
(Knisley and Hill 1993, p. 14; Knisley and Gowan 2008, p. 23). The
likelihood of being injured or killed increases if adult CPSD tiger
beetle are run over on wet or compact substrates (e.g., moist swales)
as compared to soft sands (e.g., dune faces) (Knisley and Hill 2001, p.
390). The likelihood of being hit by ORVs also increases based on the
level of ORV use. For example, the numbers of adult CPSD tiger beetles
found injured or killed by ORVs increases substantially during periods
of heavy use, such as during the Memorial Day holiday (Table 1; Knisley
and Hill 2001, p. 390). We have no information quantifying the direct
injury or mortality that ORVs cause to eggs or larval CPSD tiger beetle
because these stages are underground and not easily monitored.
TABLE 1--A comparison of the number of adult Coral Pink Sand Dunes tiger beetles found injured or killed (by off-
road vehicles) before and after a high ORV use holiday weekend (Memorial Day) from 1993 to 1998 (no survey
conducted in 1995) (Knisley and Hill 2001, p. 390).

(\1\) No data.
We do not have specific data regarding the level of impact ORVs
have on CPSD tiger beetles in the unprotected area between Conservation
Areas A and B. It is likely that many of the beetles run over by ORVs
in the dispersal corridor will be injured or killed. Thus, the ability
of adults to disperse between the central population and the northern
population is likely negatively impacted by ORVs. The result of these
ORV impacts is that the habitat between the central and northern
populations does not provide a sufficient dispersal corridor for
beetles to the northern population. Current levels of dispersal are
likely not adequate for the northern population to be self-sustaining
(see Population Viability Analysis). Thus, BLM protection of only
Conservation Area B, and the absence of protection in the dispersal
corridor, results in the continued threat of ORV use to the CPSD tiger
beetle.
Food limitation has a significant impact on tiger beetle growth,
survival, and fecundity, especially for desert species. Adult CPSD
tiger beetles are, in some years, extremely food limited and exhibit
reduced fecundity (Knisley and Gowan 2008, p. 19). Food limitation is
at least partly caused by ORV use. ORVs reduce CPSD tiger beetle prey
density and prey species diversity in CPSD (Knisley and Gowan 2006, p.
19). Ants, a primary prey item, occur in much lower densities in areas
frequented by ORVs than in areas with no ORV traffic (Knisley and Gowan
2008, p. 23). In addition, low ORV use areas in CPSD have a higher
diversity of prey species and higher numbers of prey items than high
ORV use areas (Knisley and Hill 2001, p. 389).
Prey availability significantly affects the number of larvae
produced by adult tiger beetles (Pearson and Knisley 1995, p. 165) and
the survival of larval tiger beetles (Knisley and Juliano 1988, p.
1990). Low prey densities can result in prolonged development and
decreased survivorship in larval tiger beetles and reduced size in
adults, which lowers fecundity in females (Pearson and Knisley 1985, p.
165; Knisley and Juliano 1988, p. 1990). Also, low prey densities
require larval and adult tiger beetles to spend more time searching for
food. For larval tiger beetles, this means more time near burrow
entrances searching for prey, resulting in increased susceptibility to
parasitism and predators (Pearson and Knisley 1985, p. 166). Similarly,
adults that spend more time out of their burrows searching for food
have an increased susceptibility to predation.
ORV use degrades larval habitat by reducing soil moisture. ORV use
can reduce soil moisture by churning up soils and exposing the moisture
that is locked between soil particles (beneath the surface) to greater
evaporative pressure (Shultz 1988, p. 28; Knisley and Gowan 2008, p.
10). It also reduces soil moisture by increasing soil compaction (Adams
et al. 1982, p. 167). Compaction reduces water infiltration and reduces
moisture retention in soils (Belnap 1995, p. 39).
As we discussed earlier (see Habitat), soil moisture is essential
to the CPSD tiger beetle's life history. Extreme drying or desiccation
kills tiger beetles (Knisley and Juliano 1998, p. 1990). In a dry
environment, such as the CPSD geologic feature, organisms are
constantly struggling to acquire and maintain enough water to survive.
Water is limiting to tiger beetles in CPSD, and this is evidenced by
the fact that experimental water supplementation increased larval CPSD
tiger beetle survival by 10 percent (Knisley and Gowan 2008 p. 20).
CPSD areas protected from ORV use have significantly higher soil
moistures and higher numbers of CPSD tiger beetles than adjacent ORV
use areas (Knisley and Gowan 2008, pp. 10-11).
Overall, ORV use reduces available habitat and the CPSD tiger
beetle population size. This results in a population that is at risk of
endangerment in the face of minor
[[Page 60218]]
stochastic events and minor environmental perturbations (see Factor E.
Small Population Effects).
Summary of Factor A
ORV use is a threat to the CPSD tiger beetle through direct
mortality and injury, and by reducing prey base and soil moisture. ORV
use substantially reduces habitat qualities essential to the CPSD tiger
beetle's life cycle (e.g., soil moisture and prey availability)
(Knisley and Hill 2001, p. 389; Knisley and Gowan 2008, pp. 10-11).
Reduction in habitat quality reduces reproductive success and the tiger
beetle population growth rate (e.g., Klok and de Roos 1998, pp. 205-
206). We acknowledge the very important protections of Conservation
Areas A and B from ORV use. However, despite these conservation
efforts, 52 percent of occupied swale habitat, which occurs outside of
the Conservation Areas, is currently unprotected (Figure 3, Knisley and
Gowan 2009, p. 8) and the degradation of habitat (both occupied and
potential) by ORV use reduces the ability of the population to expand
or disperse in areas outside of the Conservation Areas and thereby
reduces the population's carrying capacity. As the PVA demonstrates
(see Population Viability Analysis above), reductions in growth rate
and carrying capacity (albeit a moderate effect on PVA compared to
growth rate) increase the probability of extinction for this species.
Based on current ORV use and CPSD tiger beetle population levels, there
is a 32 percent probability that the species will go extinct in the
next 100 years, and the PVA does not consider future threats (see
Population Viability Analysis above). As we will discuss in Factor E,
environmental effects from climate change and drought conditions will
likely exacerbate reductions in soil moisture associated with ORV use,
thus increasing the extinction risk even further. The best scientific
and commercial information available indicates that the destruction,
modification, or curtailment of the CPSD tiger beetle's habitat or
range due to ORV use is a threat to the species now and in the future.
Factor B. Overutilization for Commercial, Recreational, Scientific, or
Educational Purposes
Tiger beetles are one of the most sought-after groups of insects by
amateur collectors because of the unique metallic colors and patterns
present in the various species and subspecies, as well as their
fascinating habits (Pearson et al. 2006, pp. 3-5). Interest in the
genus Cicindela is reflected in the scientific journal entitled
``Cicindela,'' which is published quarterly (since 1969) and is
exclusively devoted to the genus. In certain circumstances, collection
of these insects can add valuable information regarding biogeography,
taxonomy, and life history of the species. However, some collection is
purely recreational and adds little to no value to the scientific
understanding or conservation of tiger beetles.
Collection of adult CPSD tiger beetles, before they mate and lay
their eggs, may result in reduced population size of subsequent
generations. The magnitude of recreational collection cannot be
accurately determined for the CPSD tiger beetle, but it is likely that
some number of adults were taken in the past. However, CPSD State Park
and BLM personnel now enforce restrictions on recreational collecting
of CPSD tiger beetles, and consequently, collection levels are low
(Conservation Committee 2009, p. 17). Although scientific collection is
not restricted by any formal permitting process, only one researcher
has collected CPSD tiger beetles in approximately the last 14 years.
Over this time period, approximately 70 adults were collected (Knisley
2012, pers. comm.). The adults were collected in late May after they
had mated and oviposited eggs (Knisley 2012, pers. comm.).
Summary of Factor B
CPSD tiger beetles are not overutilized for commercial,
recreational, scientific, or educational purposes. A limited number of
CPSD tiger beetles are likely collected from wild populations for
recreational purposes; however, CPSD State Park and BLM personnel
enforce restrictions on recreational collecting. Collection of CPSD
tiger beetles for scientific investigation purposes occurs on occasion,
but the level of collection is very small. The best scientific and
commercial information available indicates that overutilization for
commercial, recreational, scientific, or educational purposes is not a
threat to the CPSD tiger beetle now nor will be in the future.
Factor C. Disease or Predation
We know of no diseases that are a threat to the CPSD tiger beetle.
Natural mortality through predation and parasitism accounts for some
individual loss of adult and larval CPSD tiger beetles (Knisley and
Hill 1994, p. 16). Known predators of adult tiger beetles include
birds, shrews (Soricidae), raccoons (Procyon lotor), lizards
(Lacertilia), toads (Bufonidae), ants (Formicidae), robber flies
(Asilidae), and dragonflies (Anisoptera) (Knisley and Shultz 1997, pp.
57-59). Despite a documented level of natural predation of CPSD tiger
beetles, effects to the species are low and not likely to limit the
CPSD tiger beetle population (Conservation Committee 2009, p. 17).
Known tiger beetle parasites include ant-like wasps of the family
Typhiidae, especially the genera Mathoca, Karlissa, and Pterombrus, and
flies of the genus Anthrax (Knisley and Shultz 1997, pp. 53-57).
Parasites predominantly target larval tiger beetles (Pearson and Vogler
2001, pp. 170-171). There are two known natural parasites of larval
CPSD tiger beetles. Bee flies (Bombyliidae) are known to flick their
eggs into beetle burrows (Knisley and Hill 1995, p. 14). When these
eggs hatch, the larval parasite feeds on beetle bodily fluids, often
resulting in death of the tiger beetle larvae. Wasps of the genus
Methoca also can parasitize CPSD tiger beetle larvae (Knisley and Hill
1995, p. 14). These wasps deposit their larvae in the burrows of larval
tiger beetles. The wasp larvae then consume the tiger beetle larvae.
Despite documented parasitism to larval CPSD tiger beetle, effects to
the species are low and not likely to limit the CPSD tiger beetle
population (Conservation Committee 1997, p. 7).
Summary of Factor C
We have found no information that indicates that disease is a
threat to the CPSD tiger beetle. There is some information documenting
mortality of CPSD tiger beetles by natural predators and parasites;
however, not to a level that significantly affects the species. Thus,
we have no information that disease, parasites, or predation is a
threat to the species now or is likely to become so in the future.
Factor D. The Inadequacy of Existing Regulatory Mechanisms
The Act requires us to examine the inadequacy of existing
regulatory mechanisms with respect to extant threats that place CPSD
tiger beetle in danger of becoming either an endangered or threatened
species. Regulatory mechanisms affecting the species fall into three
general categories: (1) Land management; (2) State mechanisms; and (3)
Federal mechanisms.
Land Management
The CPSD geologic feature is approximately 1,416 ha (3,500 ac). The
southern 809 ha (2,000 ac) of the CPSD is within the CPSD State Park
and is categorized as public land with a recreational emphasis
(Conservation
[[Page 60219]]
Committee 2009, p. 17). The State Park's mission, as described in the
most recent general management plan (Franklin et al. 2005, p. 3), is
``to provide visitors [* * *] recreation experiences while preserving
and interpreting the park's natural, scenic, and recreation
resources.'' The northern 607 ha (1,500 ac) is Federal land managed by
the BLM's Kanab Field Office (BLM 2000, p. 14). The northern area is
partly within the Moquith Mountain Wilderness Study Area (WSA). Public
education for both areas includes signage, brochures, and interpretive
programs.
As stated previously (see Factor A), the UDNR (which oversees the
Utah Division of State Parks and Recreation), the BLM, the Service, and
Kane County developed and signed a CCA in 1997 (Conservation Committee
1997), and renewed the agreement in 2009 (Conservation Committee 2009,
entire). The CCA recommends conservation objectives and actions
designed to protect and conserve the CPSD tiger beetle. Although the
CCA is not a regulatory mechanism in and of itself, the agencies have
implemented specified conservation actions, including the protection of
Conservation Areas A and B that are regulatory mechanisms. These
mechanisms are Utah Administrative Code R651-633 and the BLM's Kanab
RMP. The degree to which the CCA has ameliorated the threats is
discussed below.
Protection for the tiger beetle in Conservation Area A is enforced
according to the CPSD State Park's special closure (Conservation
Committee 1997, p. 13) and Utah's Administrative Code (R 651-633).
Conservation Area A protects some of the central population of CPSD
tiger beetle. Of the 809-ha (2,000-ac) State Park, 84 ha (207 ac) (10
percent) are closed to ORV use to provide protection for CPSD tiger
beetle habitat. Conservation Area A prohibits the use of ORVs in 48
percent of the species' known occupied swale habitat in the central
population, thereby protecting 73 to 88 percent of CPSD tiger beetle
adults and the vast majority of larvae (Figure 3, adapted from Knisley
and Gowan 2009, p. 8).
Conservation Area B provides protection to all of the northern
population's habitat as we have defined its boundary (see Figure 1),
realizing that we do not have good survey information in this area. In
this area, 150 ha (370 ac) is closed to ORV use to protect a small
population of CPSD tiger beetle. Approximately 445 ha (1,100 ac) is
available for ORV use outside of the Conservation Area B on BLM lands,
but with the stipulation that ORVs stay on open dunes and maintain a 3-
m (10-ft) buffer around vegetation. Enforcement is minimal and
primarily relies on voluntary compliance (Conservation Committee 1997,
p. 13). We have no record of enforcement effort or success of the
closures at either Conservation Area A or B.
Despite the designation and management of the Conservation Areas,
at least 52 percent of known occupied swale habitat in the central
population adjacent to Conservation Area A is open to ORV use, and an
unknown amount of habitat could be affected in the northern population
(Knisley and Gowan 2009, p. 8). As previously described, unprotected
but occupied swales have lower CPSD tiger beetle densities than nearby
protected swales that are occupied (see Figure 3).
In addition to the lack of any protection for about 52 percent of
occupied swale habitat that is outside of Conservation Area A, there is
no protection from ORV use for the CPSD tiger beetle in the dispersal
corridor between Conservation Areas A and B. As explained above (see
Adult Dispersal), this area is important for dispersal of tiger beetles
from Conservation Area A to Conservation Area B and likely is necessary
to maintain the northern CPSD tiger beetle population in Conservation
Area B.
We acknowledge the very important protections of Conservation Areas
A and B from ORV use. However, outside of the two Conservation Areas,
at least 52 percent of occupied swale habitat is currently unprotected
and the degradation of habitat (both occupied and potential) by ORV use
reduces the ability of the CPSD tiger beetle population to expand in
areas outside of protected Conservation Areas and reduces the
population's carrying capacity. The dispersal habitat between
Conservation Areas A and B is managed by the Utah Division of State
Parks and Recreation and the BLM, and used largely for OHV recreation;
no regulatory mechanisms protect the CPSD tiger beetle in this area.
At current levels of regulatory protection, CPSD tiger beetle
habitat is small and isolated in the two Conservation Areas, and the
population size is extremely small, making the species more susceptible
to other threats such as climate change and drought, demographic and
environmental stochasticity, and catastrophic events (see Factor E.
Climate Change and Drought and Small Population Effects). As explained
previously (see the Background: Population Distribution), the central
population of CPSD tiger beetle only occupies a portion of Conservation
Area A, and based on population and habitat sampling results to date,
we believe it is not likely that the species will expand to other areas
in Conservation Area A due to insufficient habitat conditions. Instead
we believe that Conservation Area A should be expanded (using
regulatory mechanisms) to protect occupied habitat that is already
being used by the species but currently is at levels that are
artificially low due to the effects of ORVs (see Population Viability
Analysis and Factor A).
In addition, the population at Conservation Area B should be
managed such that it becomes self-sustaining (see Population Viability
Analysis and Factor A). However, at this point in time it is unclear
from a regulatory perspective what will be necessary to achieve this.
It is possible that by expanding Conservation Area A, the central
population will increase such that it will be sufficient to provide
adequate numbers of dispersers to bolster the population at
Conservation Area B, thus making it self-sustaining. There may need to
be additional regulatory measures put in place to protect the dispersal
corridor between Conservation Areas A and B to allow for a safe and
sufficient level of CPSD tiger beetle dispersal between the two areas.
State Mechanisms
Utah's Administrative Code (R 651-633) prohibits motorized vehicle
use in designated nonmotorized sand dune areas of CPSD State Park.
Conservation Area A is a designated nonmotorized sand dune area, and
thus the State Code protects tiger beetle habitat in this area. CPSD
State Park's dual purpose mission statement of providing recreational
experiences while preserving natural resources (Franklin et al. 2005,
p. 3) has assisted with the conservation of CPSD tiger beetle to some
extent because the State Park has closed areas (Conservation Area A) to
ORV use to protect CPSD tiger beetle. However, the State Park also
promotes recreational use; in this case, extensive ORV use is still
permitted across the majority of the State Park, which is ultimately
detrimental to maintaining a self-sustaining population of CPSD tiger
beetles in the central area in the future (see Factor A for an analysis
of ORV impacts).
Federal Mechanisms
As mentioned previously, Conservation Area B and the northern
population are on BLM-administered land. The Federal Land Policy and
Management Act of 1976 (FLPMA) (43 U.S.C. 1701 et seq.) is the primary
[[Page 60220]]
Federal law governing most land uses on BLM-administered lands. Section
102(a)(8) of FLPMA specifically recognizes wildlife and fish resources
as being among the uses for which these lands are to be managed.
Regulations pursuant to FLPMA and the Mineral Leasing Act (30 U.S.C.
181 et seq.) that address wildlife habitat protection on BLM-
administered land include 43 CFR 3162.3-1 and 43 CFR 3162.5-1; 43 CFR
4120 et seq.; and 43 CFR 4180 et seq.
The BLM manages the CPSD tiger beetle as a ``sensitive species,''
and as stated above, BLM manages a 150-ha (370-ac) Conservation Area
for the species. The management guidance afforded sensitive species
under BLM Manual 6840--Special Status Species Management (BLM 2008,
entire) states that ``Bureau sensitive species will be managed
consistent with species and habitat management objectives in land use
and implementation plans to promote their conservation and to minimize
the likelihood and need for listing under the ESA'' (BLM 2008, p. 05V).
The BLM Manual 6840 further requires that Resource Management Plans
(RMPs) should address sensitive species, and that implementation
``should consider all site-specific methods and procedures needed to
bring species and their habitats to the condition under which
management under the Bureau sensitive species policies would no longer
be necessary'' (BLM 2008, p. 2A1). As a designated sensitive species
under BLM Manual 6840, CPSD tiger beetle conservation must be addressed
in the development and implementation of RMPs on BLM lands.
The RMPs are the basis for all actions and authorizations involving
BLM-administered lands and resources. They establish allowable resource
uses, resource condition goals and objectives to be attained, program
constraints and general management practices needed to attain the goals
and objectives, general implementation sequences, and intervals and
standards for monitoring and evaluating the plan to determine its
effectiveness and the need for amendment or revision (43 CFR 1601 et
seq.).
The RMPs provide a framework and programmatic guidance for activity
plans, which are site-specific plans written to implement decisions
made in an RMP. Activity plan decisions normally require additional
planning and National Environmental Policy Act (NEPA) analysis (see
below). If an RMP contains specific direction regarding sensitive
species habitat, conservation, or management, it represents an
enforceable regulatory mechanism to ensure that the species and its
habitats are considered during permitting and other decision-making
regarding BLM lands.
The 2008 Kanab RMP establishes guidance and objectives for the
management of the northern portion of CPSD (BLM 2008, entire). In the
RMP, the BLM commits to ``implement conservation actions identified in
the Conservation Agreement and Strategy for the Coral Pink Sand Dunes
tiger beetle, including maintaining the established 370-acre
conservation area'' (BLM 2008, p. 32). In addition to maintaining
Conservation Area B, the BLM has funded and continues to fund CPSD
tiger beetle monitoring and research activities. While these BLM-
implemented conservation actions (as outlined in the RMP) have
benefitted the CPSD tiger beetle, remaining threats (such as climate
change and drought, demographic and environmental stochasticity, and
catastrophic events (see Factor E. Climate Change and Drought and Small
Population Effects) and ORVs (see Population Viability Analysis and
Factor A)) continue to negatively affect the species.
BLM manual 6840 establishes management policy and direction for
BLM's involvement in the CCA and its membership on the Conservation
Committee (Conservation Committee 2009, p. 7). Conservation Area B was
established on BLM lands as part of the CCA and was a result of adult
and larval CPSD tiger beetle discovered in this area during a 1996
monitoring effort (Knisley and Hill 1997, p. 11; Conservation Committee
1997, entire). BLM land management practices are intended to avoid
negative effects whenever possible, while also providing for multiple-
use mandates; therefore, maintaining or enhancing CPSD tiger beetle
habitat is considered in conjunction with other agency priorities.
The BLM protects the entirety of the northern CPSD tiger beetle
population in Conservation Area B; however, this population is not
self-sustaining (see Population Distribution). As we discuss
previously, the northern population likely persists because of
dispersal from the central population (see Adult Dispersal). However,
current levels of dispersal are likely not adequate for the northern
population to be self-sustaining (see Population Viability Analysis).
The habitat between the central and northern populations (between
Conservation Areas A and B) is managed by the BLM and Utah Division of
State Parks and Recreation and is not protected from ORV use (see
Figure 2). The ORV use in this unprotected zone results in habitat
degradation and loss of beetles that are injured or killed by ORVs. The
result of these ORV impacts is that the habitat between the central and
northern populations does not provide a sufficient dispersal corridor
for beetles to the northern population (see Factor A for effects of
ORVs in CPSD tiger beetle habitat). Thus, BLM protection of only
Conservation Area B, and the absence of protection in the dispersal
corridor, results in the continued threat of ORV use to the CPSD tiger
beetle (see Factor A).
On December 15, 2009, the Environmental Protection Agency (EPA)
published in the Federal Register (74 FR 66496) a rule titled,
``Endangerment and Cause or Contribute Findings for Greenhouse Gases
Under Section 202(a) of the Clean Air Act.'' In this rule, the EPA
Administrator found that the current and projected concentrations of
the six long-lived and directly emitted greenhouse gases (GHGs)--carbon
dioxide, methane, nitrous oxide, hydrofluorocarbons, perfluorocarbons,
and sulfur hexafluoride--in the atmosphere threaten the public health
and welfare of current and future generations; and that the combined
emissions of these GHGs from new motor vehicles and new motor vehicle
engines contribute to the GHG pollution that threatens public health
and welfare (74 FR 66496). In effect, the EPA has concluded that the
GHGs linked to climate change are pollutants, whose emissions can now
be subject to the Clean Air Act (42 U.S.C. 7401 et seq.) (see 74 FR
66496). However, specific regulations to limit GHG emissions were only
proposed in 2010 and, therefore, cannot be considered an existing
regulatory mechanism. At present, we have no basis to conclude that
implementation of the Clean Air Act in the future (40 years, based on
global climate projections) will substantially reduce the current rate
of global climate change through regulation of GHG emissions.
A Federal statute that may provide protection to CPSD tiger beetle
and its habitat is the NEPA. As explained previously, Federal land
management agencies, such as the BLM, have legislation that specifies
how their lands are managed for sensitive species. The NEPA provides
authority for the Service to assume a cooperating agency role for
Federal projects undergoing evaluation for significant impacts to the
human environment. This includes participating in updates to RMPs. As a
cooperating agency, we have the opportunity to provide recommendations
to the action agency
[[Page 60221]]
to avoid impacts or enhance conservation for CPSD tiger beetle and its
habitat where it occurs on Federal land. For projects where we are not
a cooperating agency, we often review proposed actions and provide
recommendations to minimize and mitigate impacts to fish and wildlife
resources. However, acceptance of our NEPA recommendations is not
required and is at the discretion of the action agency.
Summary of Factor D
State and federally managed lands in Conservation Areas A and B
provide some protection to the CPSD tiger beetle. The northern portion
of CPSD is Federal land managed by the BLM and the southern portion of
the CPSD is within the CPSD State Park. These land management agencies
provide protection to the CPSD tiger beetle through the establishment
and regulation of the ORV restricted Conservation Areas A and B. Utah's
Administrative Code (R 651-633) prohibits motorized vehicle use in
designated nonmotorized sand dune areas of CPSD State Park
(Conservation Area A) and the BLM protects Conservation Area B.
However, as discussed under Factor A, ORV use is the primary threat to
the beetle, and this threat is not being addressed with any existing
regulatory mechanisms in the area between Conservation Areas A and B
(managed by BLM and Utah Division of State Parks and Recreation) and to
the east of Conservation Area A (managed by CPSD State Park). As a
result, the habitat quality is negatively affected, and tiger beetles
that disperse outside of the two Conservation Areas can be injured or
killed by ORVs.
The Clean Air Act gives the EPA authority to limit GHGs linked to
climate change; however, our analysis concludes that current regulation
of these gases is not adequate to reduce the current rate of global
climate change.
As evidenced by the discussion above, the species is not adequately
protected by existing regulatory mechanisms.
Factor E. Other Natural or Manmade Factors Affecting Its Continued
Existence
Natural and manmade factors affecting the CPSD tiger beetle
include: (1) Sand dune movement; (2) Climate change and drought; (3)
Small population effects; and (4) Cumulative effects of all threats
that may impact the species.
Sand Dune Movement
Movement of the swales due to sand dune movement naturally occurs
in this system as wind action continues to shape the dunes. Major dune
ridgelines moved close to 22 m (72 ft) (Knisley and Gowan 2005, p. 4)
between 2001 and 2002, and most ridgelines moved over 45 m (150 ft)
between 2002 and 2010 (Knisley and Gowan 2011, p. 25). Dune movement
can result in a change in suitable habitat conditions (Knisley and
Gowan 2008, pp. 21-22). For example, dune movement simultaneously
buries and uncovers trees in CPSD (Gregory 1950, p. 188). Similarly, we
know that dune movement is burying some previously occupied swale
habitat (Knisley and Gowan 2008, pp. 21-22). It is likely that dune
movement is uncovering potential habitat as well; however,
comprehensive surveys to determine this have not been conducted
(Knisley 2012, pers. comm.). Wind action created and continues to shape
the current CPSD (Ford et al. 2010, p. 387), and we have no evidence to
suggest that the rate of dune movement is increasing. Because CPSD
tiger beetle presumably evolved in this environment, it is likely that
the species is adapted to the continual movement of dunes. We have no
evidence demonstrating that dune movement is a threat to the species
now or is likely to become so in the future; however, additional study
of dune movement is recommended.
Climate Change and Drought
Our analyses under the Act include consideration of environmental
changes resulting from ongoing and projected changes in climate. The
terms ``climate'' and ``climate change'' are defined by the
Intergovernmental Panel on Climate Change (IPCC). ``Climate'' refers to
the mean and variability of different types of weather conditions over
time, with 30 years being a typical period for such measurements,
although shorter or longer periods also may be used (IPCC 2007a, p.
78). The term ``climate change'' thus refers to a change in the mean or
variability of one or more measures of climate (e.g., temperature or
precipitation) that persists for an extended period, typically decades
or longer, whether the change is due to natural variability, human
activity, or both (IPCC 2007a, p. 78).
Scientific measurements spanning several decades demonstrate that
changes in climate are occurring, and that the rate of change has been
faster since the 1950s. Based on extensive analyses of global average
surface air temperature, the most widely used measure of change, the
IPCC concluded that warming of the global climate system over the past
several decades is ``unequivocal'' (IPCC 2007a, p. 2). In other words,
the IPCC concluded that there is no question that the world's climate
system is warming.
Examples of other changes include substantial increases in
precipitation in some regions of the world and decreases in other
regions (for these and additional examples, see IPCC 2007a, p. 30;
Solomon et al. 2007, pp. 35-54, 82-85). Various environmental changes
(e.g., shifts in the ranges of plant and animal species, increasing
ground instability in permafrost regions, conditions more favorable to
the spread of invasive species and of some diseases, changes in amount
and timing of water availability) are occurring in association with
changes in climate (see IPCC 2007a, pp. 2-4, 30-33; and Global Climate
Change Impacts in the United States 2009, pp. 27, 79-88).
Results of scientific analyses presented by the IPCC show that most
of the observed increase in global average temperature since the mid-
20th century cannot be explained by natural variability in climate and
is ``very likely'' (defined by the IPCC as 90 percent or higher
probability) due to the observed increase in GHG concentrations in the
atmosphere as a result of human activities, particularly carbon dioxide
emissions from fossil fuel use (IPCC 2007a, pp. 5-6 and figures SPM.3
and SPM.4; Solomon et al. 2007, pp. 21-35). Further confirmation of the
role of GHGs comes from analyses by Huber and Knutti (2011, p. 4), who
concluded it is extremely likely that approximately 75 percent of
global warming since 1950 has been caused by human activities.
Scientists use a variety of climate models, which include
consideration of natural processes and variability, as well as various
scenarios of potential levels and timing of GHG emissions, to evaluate
the causes of changes already observed and to project future changes in
temperature and other climate conditions (e.g., Meehl et al. 2007,
entire; Ganguly et al. 2009, pp. 11555, 15558; Prinn et al. 2011, pp.
527, 529). All combinations of models and emissions scenarios yield
very similar projections of average global warming until about 2030.
Although projections of the magnitude and rate of warming differ after
about 2030, the overall trajectory of all the projections is one of
increased global warming through the end of this century, even for
projections based on scenarios that assume that GHG emissions will
stabilize or decline. Thus, there is strong scientific support
[[Page 60222]]
for projections that warming will continue through the 21st century,
and that the magnitude and rate of change will be influenced
substantially by the extent of GHG emissions (IPCC 2007a, pp. 44-45;
Meehl et al. 2007, pp. 760-764; Ganguly et al. 2009, pp. 15555-15558;
Prinn et al. 2011, pp. 527, 529).
In addition to basing their projections on scientific analyses, the
IPCC reports projections using a framework for treatment of
uncertainties (e.g., they define ``very likely'' to mean greater than
90 percent probability, and ``likely'' to mean greater than 66 percent
probability; see Solomon et al. 2007, pp. 22-23). Some of the IPCC's
key projections of global climate and its related effects include: (1)
It is virtually certain there will be warmer and more frequent hot days
and nights over most of the earth's land areas; (2) it is very likely
there will be increased frequency of warm spells and heat waves over
most land areas; (3) it is very likely that the frequency of heavy
precipitation events, or the proportion of total rainfall from heavy
falls, will increase over most areas; and (4) it is likely the area
affected by droughts will increase, that intense tropical cyclone
activity will increase, and that there will be increased incidence of
extreme high sea level (IPCC 2007b, p. 8, Table SPM.2). More recently,
the IPCC published additional information that provides further insight
into observed changes since 1950, as well as projections of extreme
climate events at global and broad regional scales for the middle and
end of this century (IPCC 2011, entire).
Various changes in climate may have direct or indirect effects on
species. These may be positive, neutral, or negative, and they may
change over time, depending on the species and other relevant
considerations, such as interactions of climate with other variables
such as habitat fragmentation (for examples, see Franco et al. 2006;
IPCC 2007, pp. 8-14, 18-19; Forister et al. 2010; Galbraith et al.
2010; Chen et al. 2011). In addition to considering individual species,
scientists are evaluating possible climate change-related impacts to,
and responses of, ecological systems, habitat conditions, and groups of
species; these studies include acknowledgement of uncertainty (e.g.,
Deutsch et al. 2008; Berg et al. 2009; Euskirchen et al. 2009;
McKechnie and Wolf 2009; Sinervo et al. 2010; Beaumont et al. 2011;
McKelvey et al. 2011; Rogers and Schindler 2011).
Many analyses involve elements that are common to climate change
vulnerability assessments. In relation to climate change, vulnerability
refers to the degree to which a species (or system) is susceptible to,
and unable to cope with, adverse effects of climate change, including
climate variability and extremes. Vulnerability is a function of the
type, magnitude, and rate of climate change and variation to which a
species is exposed, its sensitivity, and its adaptive capacity (IPCC
2007a, p. 89; see also Glick et al. 2011, pp. 19-22). There is no
single method for conducting such analyses that applies to all
situations (Glick et al. 2011, p. 3). We use our expert judgment and
appropriate analytical approaches to weigh relevant information,
including uncertainty, in our consideration of various aspects of
climate change.
As is the case with all stressors that we assess, even if we
conclude that a species is currently affected or is likely to be
affected in a negative way by one or more climate-related impacts, it
does not necessarily follow that the species meets the definition of an
``endangered species'' or a ``threatened species'' under the Act. If a
species is listed as an endangered or threatened species, knowledge
regarding its vulnerability to, and known or anticipated impacts from,
climate-associated changes in environmental conditions can be used to
help devise appropriate strategies for its recovery.
The IPCC predicts that the resiliency of many ecosystems is likely
to be exceeded this century by an unprecedented combination of climate
change, associated disturbances (e.g., flooding, drought, wildfire, and
insects), and other global drivers (IPCC 2007, pp. 31-33). With medium
confidence, IPCC predicts that approximately 20 to 30 percent of plant
and animal species assessed by the IPCC so far are likely to be at an
increased risk of extinction if increases in global average temperature
exceed 1.5 to 2.5 [deg]C (3 to 5 [deg]F) (IPCC 2007, p. 48).
Regional projections indicate the Southwest, including southern
Utah, may experience the greatest temperature increase of any area in
the lower 48 States (IPCC 2007, p. 30). Drought probability is
predicted to increase in the Southwest (Karl et al. 2009, pp. 129-134),
with summers warming more than winters, and annual temperature
increasing approximately 2.2 [deg]C (4[emsp14][deg]F) by 2050 (Ray et
al. 2008, p. 29). Additionally, the number of days over 32 [deg]C
(90[emsp14][deg]F) could double by the end of the century (Karl et al.
2009, p. 34). Projections also show declines in snowpack across the
West, with the most dramatic declines at lower elevations (below 2,500
m (8,200 ft)) (Ray et al. 2008, p. 29). A 10 to 30 percent decrease in
precipitation in mid-latitude western North America is projected by the
year 2050, based on an ensemble of 12 climate models (Milly et al.
2005, p. 1). Overall, future projections for the Southwest include
increased temperatures; more intense and longer-lasting heat waves; and
increased probability of drought exacerbated by higher temperatures,
heavier downpours, increased flooding, and increased erosion (Karl et
al. 2009, pp. 129-134).
Utah is projected to warm more than the average for the entire
globe (Governor's Blue Ribbon Advisory Council on Climate Change
(GBRAC) 2008, p. 14). The expected consequences of this warming are
fewer frost days, longer growing seasons, and more heat waves (GBRAC
2008, p. 14). For Utah, the projected increase in annual mean
temperature by year 2100 is about 4.5 [deg]C (8[emsp14][deg]F) (GBRAC
2008, p. 14). Because of increased temperature, Utah soils are expected
to dry more rapidly (GBRAC 2008, p. 20); this is likely to result in
reduced soil moisture levels in CPSD tiger beetle habitat.
Utah is projected to have more frequent heavy precipitation events,
separated by longer dry spells as a result of climate change (GBRAC
2008, p. 15). Drought is a localized dry spell. Drought conditions are
a threat to the CPSD tiger beetle, as rainfall indirectly controls
population size and the changing dynamics of the species (Knisley and
Gowan 2009, p. 8).
Previous drought-like conditions have resulted in drastic CPSD
tiger beetle population declines. For example, low rainfall amounts
from 2001 to 2003 resulted in reduced adult numbers in 2004 and 2005
(Knisley and Gowan 2008, p. 8). Conversely, high adult numbers in 1996
and 2002 followed several years of higher than average rainfall
(Knisley and Gowan 2008, p. 8). These observed population responses to
rainfall are most likely caused by reductions and increases in prey and
soil moisture. Prey is more abundant during wet years, and this reduces
the effects of starvation, decreases development time, and increases
fecundity (Knisley and Hill 2001, p. 391). Soil moisture seems to have
the greatest effect on oviposition and larval survival. As stated in
Factor A, water is limiting to tiger beetles in CPSD, and this is
evidenced by the fact that in one experiment water supplementation
increased larval CPSD tiger beetle survival by 10 percent (Knisley and
Gowan 2006, p. 7).
In summary, the limited geographic range of CPSD tiger beetle to
high-elevation sand dunes and swales within the CPSD geologic feature
limits the
[[Page 60223]]
ability of the species to adapt by shifting its range in response to
changing climatic conditions. CPSD tiger beetle survival and
reproduction, as described above, are highly dependent upon soil
moisture, which in turn is dependent upon climatic conditions
(precipitation and temperature). Climate change is predicted to
increase temperatures and increase the likelihood and duration of
drought conditions in Utah. Both of these effects will reduce soil
moisture in CPSD and impact CPSD tiger beetle, and for this reason, we
conclude that environmental changes resulting from climate change,
including drought, will be a threat to this species in the future.
Small Population Effects
Under this factor we consider the small population size of CPSD
tiger beetle has one of the smallest geographical ranges of any known
insect (Romey and Knisley 2002, p. 170). It is restricted to the CPSD
and occupies only 202 ha (500 ac) (Morgan et al. 2000, p. 1109).
A species may be considered rare because of a limited geographical
range, specialized habitat, or small population size (Primack 1998, p.
176). In the absence of information identifying threats to a species
and linking those threats to the rarity of a species, we do not
consider rarity alone to be a threat. A species that has always been
rare, yet continues to survive, could be well equipped to continue to
exist into the future. Many naturally rare species have persisted for
long periods within small geographic areas, and many naturally rare
species exhibit traits that allow them to persist despite their small
population sizes. Consequently, the fact that a species is rare does
not necessarily indicate that it may be in danger of extinction.
CPSD tiger beetle has a very limited occupied range and a very
small population size (558 adults in 2005 to a high of 2,944 adults in
2002). It has several characteristics typical of species vulnerable to
extinction including: (1) A very narrow geographic range; (2) only one
known self-sustaining population; and (3) a small population size.
Extinction may be caused by demographic stochasticity due to chance
realizations of individual probabilities of death and reproduction,
particularly in small populations (Shaffer 1981, p. 131; Lande 1993,
pp. 911-912). Environmental stochasticity can result in extinction
through a series of small or moderate perturbations that affect birth
and death rates within a population (Shaffer 1981, p. 131; Lande 1993,
p. 912). Lastly, extinction can be caused by random catastrophes
(Shaffer 1981, p. 131; Lande 1993, p. 912). CPSD tiger beetle is
vulnerable to extinction due to: (1) Demographic stochasticity due to
its small population size; (2) environmental stochasticity due to
continued small perturbations caused by ongoing modification and
curtailment of its habitat and range from ORV use; and (3) the chance
of random catastrophe such as an extended drought.
Small populations also can be vulnerable due to a lack of genetic
diversity (Shaffer 1981, p. 132). We have no information regarding
genetic diversity of CPSD tiger beetle. A minimum viable population
(MVP) will vary depending on the species. An MVP of 1,000 may be
adequate for species of normal genetic variability, and an MVP of
10,000 should permit long-term persistence and continued genetic
diversity (Thomas 1990, p. 325). These estimates should be increased by
at least 1 order of magnitude (to 10,000 and 100,000) for insects,
because they usually have greater population variability (Thomas 1990,
p. 326). Based upon available information, CPSD tiger beetle likely
does not meet these minimum population criteria for maintaining genetic
diversity because the estimated population size ranges from 558 to
2,944 individuals.
We do not believe that small population size on its own would be a
threat to CPSD tiger beetle. However, the species' small population
size makes it more vulnerable to extinction due to demographic
stochasticity, environmental stochasticity, and random catastrophe when
combined with the specific threats of ORV use, drought and climate
change. Thus, we consider small population size a threat to the
species, now and is likely to become so in the future, as is discussed
in more detail below.
Cumulative Impacts
Some of the threats discussed in Factors A through E can work in
concert with one another to cumulatively create conditions that will
impact CPSD tiger beetle beyond the scope of each individual threat.
ORV use and the drought-related effects of climate change can reduce
soil moisture. Rainfall and associated soil moisture is a critical
factor for desert tiger beetles (Knisley and Juliano 1988, entire) and
is likely the most important natural factor affecting population
dynamics of CPSD tiger beetle. Currently, water availability limits the
tiger beetle population in the CPSD (Knisley and Gowan 2006, p. 7).
As explained in previous sections (see Factor A), reduced
precipitation reduces soil moisture directly, and drought and effects
of climate change result in increased temperatures which dry soils more
quickly. ORV use can reduce soil moisture by churning up soils and
exposing the moisture that is locked up between soil particles, and it
can also compact soil, which reduces water infiltration and reduces
moisture retention in soils. Cumulatively, reduced precipitation and
increased evaporation (caused by the drought-related effects of climate
change), and soil compaction and soil exposure (caused by ORV use) will
further dry soils that are already moisture limited. This drying could
result in a further shrinking of available CPSD tiger beetle habitat
and thus decrease population size, because less habitat will be
suitable for larval tiger beetles and because drying of habitat reduces
prey abundance. For these reasons, we find that ORV use and drought-
related effects of climate change are a threat to the species both
independently (presently in the case of ORV use) and cumulatively in
the future.
Summary of Factor E
Wind action created and continues to shape the CPSD (Ford et al.
2010, p. 387). Sand dune movement naturally occurs in this system as
wind action continues to shape the dunes. Dune movement can result in a
change in suitable habitat conditions (Knisley and Gowan 2008, pp. 21-
22); however, it is likely that dune movement is uncovering potential
habitat as well as covering previously occupied habitat (e.g., Gregory
1950, p. 188). CPSD tiger beetle evolved in a dynamic dune-dominated
system, and we have no evidence to suggest that the rate of dune
movement is increasing or decreasing. Thus, we have no information
indicating that dune movement is a threat to this species, now or is
likely to become so in the future.
Utah is predicted to have increased temperatures and more frequent
heavy precipitation events, separated by longer dry spells, as a result
of climate change (GBRAC 2008, p. 15). Utah soils are expected to dry
more rapidly as a result of increased temperatures (GBRAC 2008, p. 20).
Drought duration and intensity in CPSD will likely increase in the
future, magnifying the soil moisture reductions expected from
temperature increases alone. Precipitation and soil moisture levels
currently limit the CPSD tiger beetle population in CPSD (Knisley and
Gowan 2006, p. 7), and reductions in soil moisture associated with
climate change and drought will further reduce the CPSD tiger beetle
population size. Based on the analysis in Factor E, we find
environmental changes resulting
[[Page 60224]]
from climate change and drought, will become threats to the CPSD tiger
beetle in the future.
The restricted range of the species does not constitute a threat in
itself. However, the species' small population size makes the species
more vulnerable to extinction due to demographic stochasticity,
environmental stochasticity, and random ecatastrophe, when combined
with the specific threats of ORV use, drought, and climate change.
Therefore, we consider its small population size to be a threat to the
species when combined with other stressors and threats.
Threats can work in concert with one another to cumulatively create
conditions that will impact CPSD tiger beetle beyond the scope of each
individual threat. Climate change, drought, and ORV use all act upon
CPSD tiger beetle through a similar mechanism: The drying of soils. As
we discussed, soil moisture is a critical factor for desert tiger
beetles (Knisley and Juliano 1988, entire) and water and soil moisture
are both currently limiting CPSD tiger beetle (Knisley and Gowan 2006,
p. 7). Reduced precipitation, increased evaporation, soil compaction,
and soil exposure act cumulatively on CPSD tiger beetle and its
habitat. For these reasons, we find ORV use, environmental changes
resulting from climate change, and drought are threats to the species
both independently (presently in the case of ORV use) and cumulatively.
The best scientific and commercial information available indicates that
other natural or manmade factors affecting its continued existence are
a threat the CPSD tiger beetle, now and are likely to continue to be so
in the future.
Determination
We have carefully assessed the best scientific and commercial
information available regarding the past, present, and future threats
to CPSD tiger beetle. The Act defines an endangered species as any
species that is ``in danger of extinction throughout all or a
significant portion of its range'' and a threatened species as any
species ``that is likely to become endangered throughout all or a
significant portion of its range within the foreseeable future.'' Under
the Act and our implementing regulations, a species may warrant listing
if it is in danger of extinction or likely to become so throughout all
or a significant portion of its range. CPSD tiger beetle is highly
restricted in its range, threats occur throughout its range, and are
not restricted to any particular significant portion of that range.
Accordingly, our assessment and determination applies to the species
throughout its entire range.
CPSD tiger beetle has one of the smallest geographical ranges of
any known insect (Romey and Knisley 2002, p. 170). It is restricted to
the CPSD geologic feature and occupies only 202 ha (500 ac) (Morgan et
al. 2000, p. 1109). Within CPSD, CPSD tiger beetle occur sporadically
throughout the dunes, but only consistently exist in two populations
that are separated by 4.8 km (3 mi). The northern population is not
self-sustaining (Knisley 2001, p. 9) and likely persists because of
periodic dispersal from the central population. Extremely low numbers
and a highly restricted geographic range make CPSD tiger beetle
particularly susceptible to becoming in danger of extinction due to
existing threats and threats in the foreseeable future.
ORV use and small population effects, in combination with other
stressors, are threats to the species (see Factors A, D, and E). These
factors pose immediate threats to the species because they are ongoing.
ORV use, small population effects, climate change and drought, and the
cumulative impacts of ORV use and climate change and drought will
threaten the species in the foreseeable future (see Factors A, D, and
E).
Despite ongoing threats, the adult CPSD tiger beetle population
size has shown a stable or slightly increasing trend since 2003, but
overall trend since 1992 suggests that the population is in decline.
Recreational ORV use has reduced the amount of habitat available to
CPSD tiger beetle and in this way suppresses the species population
size. However, as the past 9 years of population data suggest, it is
unlikely that the threat of ORV use will cause imminent extinction for
the species. It is more likely that, absent the protections of the Act,
ORV use will continue to suppress the CPSD tiger beetle population
size, and future drought conditions associated with climate change
would act cumulatively with ORV use upon an extremely small population,
causing endangerment. Because endangerment in this case is ``in the
foreseeable future'' and the species is currently (over about the last
5 years) experiencing a stable or increasing population trend, we do
not consider CPSD tiger beetle to be presently on the brink of
extinction, but likely to become so in the future (Capone 2012,
entire).
Therefore, on the basis of the best available scientific and
commercial information, we propose listing CPSD tiger beetle as a
threatened species in accordance with sections 3(6) and 4(a)(1) of the
Act. Because threats are distributed across the limited range of the
species, we have determined that the CPSD tiger beetle is a threatened
species throughout all of its range.
Available Conservation Measures
Conservation measures provided to species listed as endangered or
threatened under the Act include recognition, recovery actions,
requirements for Federal protection, and prohibitions against certain
practices. Listing results in public awareness and conservation by
Federal, State, Tribal, and local agencies, private organizations, and
individuals. The Act encourages cooperation with the States and
requires that recovery actions be carried out for all listed species.
The protection required by Federal agencies and the prohibitions
against certain activities are discussed, in part, below.
The primary purpose of the Act is the conservation of endangered
and threatened species and the ecosystems upon which they depend. The
ultimate goal of such conservation efforts is the recovery of these
listed species, so that they no longer need the protective measures of
the Act. Subsection 4(f) of the Act requires the Service to develop and
implement recovery plans for the conservation of endangered and
threatened species. The recovery planning process involves the
identification of actions that are necessary to halt or reverse the
species' decline by addressing the threats to its survival and
recovery. The goal of this process is to restore listed species to a
point where they are secure, self-sustaining, and functioning
components of their ecosystems.
Recovery planning includes the development of a recovery outline
shortly after a species is listed, preparation of a draft and final
recovery plan, and revisions to the plan as significant new information
becomes available. The recovery outline guides the immediate
implementation of urgent recovery actions and describes the process to
be used to develop a recovery plan. The recovery plan identifies site-
specific management actions that will achieve recovery of the species,
measurable criteria that determine when a species may be downlisted or
delisted, and methods for monitoring recovery progress. Recovery plans
also establish a framework for agencies to coordinate their recovery
efforts and provide estimates of the cost of implementing recovery
tasks. Recovery teams (comprising species experts, Federal and State
agencies, nongovernmental organizations, and stakeholders) are often
established to develop recovery plans. When completed, the recovery
[[Page 60225]]
outline, draft recovery plan, and the final recovery plan will be
available on our Web site (https://www.fws.gov/endangered), or from our
Utah Field Office (see FOR FURTHER INFORMATION CONTACT).
Implementation of recovery actions generally requires the
participation of a broad range of partners, including other Federal
agencies, States, Tribes, nongovernmental organizations, businesses,
and private landowners. Examples of recovery actions include habitat
restoration (e.g., restoration of native vegetation), research, captive
propagation and reintroduction, and outreach and education. The
recovery of many listed species cannot be accomplished solely on
Federal lands because their range may occur primarily or solely on non-
Federal lands. To achieve recovery of these species requires
cooperative conservation efforts on private, State, and Tribal lands.
If this species is listed, funding for recovery actions will be
available from a variety of sources, including Federal budgets, State
programs, and cost share grants for non-Federal landowners, the
academic community, and nongovernmental organizations. In addition,
pursuant to section 6 of the Act, the State of Utah would be eligible
for Federal funds to implement management actions that promote the
protection and recovery of CPSD tiger beetle. Information on our grant
programs that are available to aid species recovery can be found at:
https://www.fws.gov/grants.
Although CPSD tiger beetle is only proposed for listing under the
Act at this time, please let us know if you are interested in
participating in recovery efforts for this species. Additionally, we
invite you to submit any new information on this species whenever it
becomes available and any information you may have for recovery
planning purposes (see FOR FURTHER INFORMATION CONTACT).
Section 7(a) of the Act requires Federal agencies to evaluate their
actions with respect to any species that is proposed or listed as
endangered or threatened and with respect to its critical habitat, if
any is designated. Regulations implementing this interagency
cooperation provision of the Act are codified at 50 CFR part 402.
Section 7(a)(4) of the Act requires Federal agencies to confer with the
Service on any action that is likely to jeopardize the continued
existence of a species proposed for listing or result in destruction or
adverse modification of proposed critical habitat. If a species is
listed subsequently, section 7(a)(2) of the Act requires Federal
agencies to ensure that activities they authorize, fund, or carry out
are not likely to jeopardize the continued existence of the species or
destroy or adversely modify its critical habitat. If a Federal action
may affect a listed species or its critical habitat, the responsible
Federal agency must enter into formal consultation with the Service.
Federal agency actions within the species' habitat that may require
conference or consultation or both as described in the preceding
paragraph include management and any other landscape altering
activities on Federal lands administered by the BLM; construction and
management of gas pipeline and power line rights-of-way by the Federal
Energy Regulatory Commission; and construction and maintenance of roads
or highways by the Federal Highway Administration.
We may issue permits to carry out otherwise prohibited activities
involving endangered and threatened wildlife species under certain
circumstances. Regulations governing permits are codified at 50 CFR
17.32 for threatened species. With regard to endangered wildlife, a
permit must be issued for the following purposes: For scientific
purposes, to enhance the propagation or survival of the species, and
for incidental take in connection with otherwise lawful activities.
Questions regarding whether specific activities would constitute a
violation of section 9 of the Act should be directed to the U.S. Fish
and Wildlife Service, Utah Field Office (see FOR FURTHER INFORMATION
CONTACT). Requests for copies of the regulations concerning listed
animals and general inquiries regarding prohibitions and permits may be
addressed to the U.S. Fish and Wildlife Service, Endangered Species
Permits, 134 Union Boulevard, Suite 650, Lakewood, CO 80228; Telephone

Proposed Critical Habitat Designation for the Coral Pink Sand Dunes
Tiger Beetle
Background
Critical habitat is defined in section 3 of the Act as:
(1) The specific areas within the geographical area occupied by the
species, at the time it is listed in accordance with the Act, on which
are found those physical or biological features:
(a) Essential to the conservation of the species, and
(b) Which may require special management considerations or
protection; and
(2) Specific areas outside the geographical area occupied by the
species at the time it is listed, upon a determination that such areas
are essential for the conservation of the species.
Conservation, as defined under section 3 of the Act, means to use
all methods and procedures that are necessary to bring an endangered or
threatened species to the point at which the measures provided pursuant
to the Act are no longer necessary. Such methods and procedures
include, but are not limited to, all activities associated with
scientific resources management such as research, census, law
enforcement, habitat acquisition and maintenance, propagation, live
trapping, and transplantation, and, in the extraordinary case where
population pressures within a given ecosystem cannot be otherwise
relieved, may include regulated taking.
Critical habitat receives protection under section 7 of the Act
through the requirement that Federal agencies ensure, in consultation
with the Service, that any action they authorize, fund, or carry out is
not likely to result in the destruction or adverse modification of
critical habitat. The designation of critical habitat does not affect
land ownership or establish a refuge, wilderness, reserve, preserve, or
other conservation area. Such designation does not allow the government
or public to access private lands. Such designation does not require
implementation of restoration, recovery, or enhancement measures by
non-Federal landowners. Where a landowner seeks or requests Federal
agency funding or authorization for an action that may affect a listed
species or critical habitat, the consultation requirements of section
7(a)(2) would apply, but even in the event of a destruction or adverse
modification finding, the obligation of the Federal action agency and
the landowner is not to restore or recover the species, but to
implement reasonable and prudent alternatives to avoid destruction or
adverse modification of critical habitat.
Under the first prong of the Act's definition of critical habitat,
areas within the geographical area occupied by the species at the time
it was listed are included in a critical habitat designation if they
contain physical or biological features (1) which are essential to the
conservation of the species and (2) which may require special
management considerations or protection. For these areas, critical
habitat designations identify, to the extent known using the best
scientific and commercial data available, those physical or biological
features that are essential to the conservation of the
[[Page 60226]]
species (such as space, food, cover, and protected habitat). In
identifying those physical and biological features within an area, we
focus on the Primary Constituent Elements (PCEs), such as roost sites,
nesting grounds, seasonal wetlands, water quality, tide, and soil type,
that are essential to the conservation of the species.
Under the second prong of the Act's definition of critical habitat,
we can designate critical habitat in areas outside the geographical
area occupied by the species at the time it is listed, upon a
determination that such areas are essential for the conservation of the
species. For example, an area currently occupied by the species but
that was not occupied at the time of listing may be essential to the
conservation of the species and may be included in the critical habitat
designation. We designate critical habitat in areas outside the
geographical area occupied by a species only when a designation limited
to its range would be inadequate to ensure the conservation of the
species.
Section 4 of the Act requires that we designate critical habitat on
the basis of the best scientific data available. Further, our Policy on
Information Standards under the Act (published in the Federal Register
on July 1, 1994 (59 FR 34271)), the Information Quality Act (section
515 of the Treasury and General Government Appropriations Act for
Fiscal Year 2001 (Pub. L. 106-554; H.R. 5658)), and our associated
Information Quality Guidelines, provide criteria, establish procedures,
and provide guidance to ensure that our decisions are based on the best
scientific data available. They require our biologists, to the extent
consistent with the Act and with the use of the best scientific data
available, to use primary and original sources of information as the
basis for recommendations to designate critical habitat.
When we are determining which areas should be designated as
critical habitat, our primary source of information is generally the
information developed during the listing process for the species.
Additional information sources may include the recovery plan for the
species, articles in peer-reviewed journals, conservation plans
developed by States and counties, scientific status surveys and
studies, biological assessments, other unpublished materials, or
experts' opinions or personal knowledge.
Habitat is dynamic, and species may move from one area to another
over time. We recognize that critical habitat designated at a
particular point in time may not include all of the habitat areas that
we may later determine are necessary for the recovery of the species.
For these reasons, a critical habitat designation does not signal that
habitat outside the designated area is unimportant or may not be needed
for recovery of the species. Areas that are important to the
conservation of the species, both inside and outside the critical
habitat designation, will continue to be subject to: (1) Conservation
actions implemented under section 7(a)(1) of the Act, (2) regulatory
protections afforded by the requirement in section 7(a)(2) of the Act
for Federal agencies to ensure their actions are not likely to
jeopardize the continued existence of any endangered or threatened
species, and (3) the prohibitions of section 9 of the Act if actions
occurring in these areas may affect the species. Federally funded or
permitted projects affecting listed species outside their designated
critical habitat areas may still result in jeopardy findings in some
cases. These protections and conservation tools will continue to
contribute to recovery of this species. Similarly, critical habitat
designations made on the basis of the best available information at the
time of designation will not control the direction and substance of
future recovery plans, Habitat Conservation Plans (HCPs), or other
species conservation planning efforts if new information available at
the time of these planning efforts calls for a different outcome.
Physical or Biological Features
In accordance with section 3(5)(A)(i) and 4(b)(1)(A) of the Act and
regulations at 50 CFR 424.12, in determining which areas within the
geographical area occupied by the species at the time of listing to
designate as critical habitat, we consider the physical or biological
features essential to the conservation of the species and which may
require special management considerations or protection. These include,
but are not limited to:
(1) Space for individual and population growth and for normal
behavior;
(2) Food, water, air, light, minerals, or other nutritional or
physiological requirements;
(3) Cover or shelter;
(4) Sites for breeding, reproduction, or rearing (or development)
of offspring; and
(5) Habitats that are protected from disturbance or are
representative of the historical, geographical, and ecological
distributions of a species.
We derive the specific physical or biological features required for
CPSD tiger beetle from studies of this species' habitat, ecology, and
life history as described below. We have determined that CPSD tiger
beetle requires the following physical or biological features:
Space for Individual and Population Growth
Dune System--CPSD consists of a series of high, mostly barren, dry
dune ridges separated by lower, moister, and more vegetated interdunal
swales (Romey and Knisley 2002, p. 170). The CPSD tiger beetle requires
interconnected dune and swale habitats for thermoregulation, foraging,
reproduction, and larval development. Adult CPSD tiger beetles use most
of the dune area from the swales (low place between sand dunes) to the
upper dune slope for foraging and thermoregulation. Larval CPSD tiger
beetles are more restricted to moist, vegetated swale areas (Knisley
and Hill 2001, p. 386). Therefore, based on the information above we
identify sand dunes and swales within the CPSD geologic feature as an
essential physical or biological feature for this species.
Climate--The CPSD tiger beetle occurs only at the CPSD geologic
feature in southern Utah. CPSD elevation ranges from a low of 1,710 m
(5,620 ft) to a high of 2,090 m (6,850 ft) (Ford et al. 2010, p. 381).
The nearest weather station, in Kanab, Utah, has a mean annual
temperature of 12.4 [deg]C (54.4 [deg]F) and mean annual precipitation
of 33.8 cm (13.3 inches) with winter-summer precipitation peaks and
spring-autumn drought (Ford et al. 2010, p. 381). These climatic
conditions are influenced, in part, by elevation. Rainfall and the
associated increase in soil moisture have a positive effect on CPSD
tiger beetle oviposition and survivorship (Knisley and Hill 2001, p.
391) and the areas in the dune field with the highest soil moisture
contain the highest densities of larvae (Knisley and Gowan 2011, p.
22). Because the CPSD tiger beetle has evolved in these climatic
conditions and because precipitation and moisture are important to
survival, we identify suitable precipitation regimes, a dry spring and
fall, and winter and summer precipitation as essential physical or
biological features for this species.
Food, Water, Air, Light, Minerals, or Other Nutritional or
Physiological Requirements
Food--CPSD tiger beetle are predatory insects. Adults are active,
visual hunters that use their large mandibles to capture and eat small
arthropods. Adults primarily forage on dune faces and
[[Page 60227]]
swale edges (Hill and Knisley 1996, p. 9). Adults are food limited in
some years, which results in reduced fecundity (Knisley and Gowan 2008,
p. 19). Larvae are sedentary predators that live in permanent burrows
in the ground and use large mandibles to capture small arthropods that
pass near their burrow. CPSD tiger beetle feed primarily on ants,
flies, and other small arthropods (Knisley and Hill 1993, p. 13).
In summary, CPSD tiger beetle is food limited in some years. Both
adults and larvae use their large mandibles to capture arthropods.
Their primary prey are ants, flies, and other small arthropods.
Therefore, based on the information above, we identify an abundant and
diverse arthropod prey base to be an essential physical or biological
feature for this species.
Cover or Shelter
Adult Burrows--Adult CPSD tiger beetle use cover or shelter to help
maintain internal body temperatures (thermoregulation). During peak
spring and fall activity, when it is sunny, adults are usually active
early (9 a.m.-2 p.m.) and again in late afternoon (4 p.m.-7 p.m.)
(Knisley and Hill 1993, pp.13-14). They dig and reside in the sand in
burrows to avoid unfavorable weather conditions such as hot mid-
afternoons or daytime conditions that are cool or rainy (Knisley and
Hill 1993, p. 14). Shade provided by vegetative cover also is important
for thermoregulation during warmer periods (Knisley 2012, pers. comm.).
Therefore, based on the information above, we identify sand dunes and
vegetation as an essential physical or biological feature for this
species.
Sites for Breeding, Reproduction, or Rearing (or Development) of
Offspring
Larval Beds--Adult females determine the larval microhabitat by
their selection of an oviposition site (Knisley and Gowan 2011, p. 6).
Newly hatched larvae construct burrows in sand soils at the site of
oviposition and subsequently pass through three larval stages (each
stage is called an ``instar'') before pupating and then emerging to the
adult form. Larvae remain in the same burrow throughout their
development and only rarely move outside of their burrow to dig a new
burrow in a more favorable location (Knisley and Hill 1996, p. 11).
Most larvae occur within the swale bottoms and up the lower slopes
of the dunes, particularly where the soil or subsoil is moist most of
the time (Knisley and Hill 1996, p. 11; Knisley and Gowan 2011, p. 22).
Larvae primarily inhabit areas with 3 to 25 percent soil moisture
(Romney and Knisley 2002, p. 172). Soil moisture is critical to larval
CPSD tiger beetle survival. Drying or desiccation can kill tiger
beetles (Knisley and Juliano 1998, p. 1990), and almost no larvae
survive below 3 percent soil moisture (Romen and Knisley 2002, p. 172).
Water tends to be so limiting in CPSD that water supplementation
increases larval CPSD tiger beetle survival by 10 percent (Knisley and
Gowan 2006, p. 7). We are not aware of an upper limit, in terms of soil
moisture, where increases in soil moisture are detrimental to larval
CPSD tiger beetle survival.
Larvae are most common in swales with a relatively high total
percent vegetation cover (means of 23 to 57 percent) (Knisley and Hill
2001, p. 389). The swale vegetation supports the prey base of ants,
flies, and other prey upon which larvae depend. Low or no vegetation
results in a reduced prey base. Vegetative cover above 57 percent tends
to stabilize sediments too much and may prevent adults from ovipositing
(Knisley 2012, pers. comm.).
In summary, adult ovipositing determines the habitats used by
larval CPSD tiger beetle. Soil moisture and prey availability are
essential for larval growth and survival. Vegetation supports the prey
base; however, too much vegetation cover can make habitat unsuitable
for ovipositing. Therefore, based on the information above, we identify
swale habitat, soil moisture, an abundant and diverse prey base, and 23
to 57 percent vegetation cover as the essential physical or biological
features for this species.
Primary Constituent Elements for CPSD Tiger Beetle
Under the Act and its implementing regulations, we are required to
identify the physical or biological features essential to the
conservation of CPSD tiger beetle in areas occupied at the time of
listing, focusing on the features' PCEs. We consider PCEs to be the
elements of physical or biological features that are all needed to
provide for a species' life-history processes and are essential to the
conservation of the species.
Based on our current knowledge of the physical or biological
features and habitat characteristics required to sustain the species'
life-history processes, we determine that the PCEs specific to CPSD
tiger beetle are: Dynamic sand dunes and swales within the Coral Pink
Sand Dunes geologic feature that have:
[cir] Elevations from 1,710 to 2,090 m;
[cir] Appropriate levels of moisture and compaction to allow for
burrowing (greater than 3 percent); and
[cir] Vegetative cover of 23-57% that allows for ovipositing, adult
thermoregulation, and abundant prey.
With this proposed designation of critical habitat, we intend to
identify the physical or biological features essential to the
conservation of the species, through the identification of PCEs
sufficient to support the life-history processes of the species. All
units and subunits proposed for designation as critical habitat are
currently occupied by CPSD tiger beetle and contain the PCEs sufficient
to support the life-history needs of the species.
Special Management Considerations or Protection
When designating critical habitat, we assess whether the specific
areas within the geographical area occupied by the species at the time
of listing contain features which are essential to the conservation of
the species and which may require special management considerations or
protection. A detailed discussion of threats to CPSD tiger beetle and
its habitat can be found in the Summary of Factors Affecting the
Species section.
The primary threats impacting the physical and biological features
essential to the conservation of CPSD tiger beetle that may require
special management considerations or protection within the proposed
critical habitat include, but are not limited to, ORV use, drought, and
climate change, and the cumulative effects of all of these threats.
The features essential to the conservation of this species (sand
dunes, moist and vegetated swales, and prey species) may require
special management considerations or protection to reduce threats.
Extremely low numbers and a highly restricted geographic range make
CPSD tiger beetle particularly susceptible to extinction in the
foreseeable future. Special management considerations or protections
are required within critical habitat areas to address threats.
Management activities that could ameliorate threats include (but are
not limited to): The establishment of a second self-sustaining
population; regulations and/or agreements that balance conservation
with ORV use in areas that would affect the species; the designation of
additional protected areas with specific provisions and protections for
the species; and the elimination or avoidance of activities that alter
the soil moisture, vegetation community, or prey base in swale
[[Page 60228]]
habitat. These management activities would protect the PCEs for the
species by preventing the loss of habitat and individuals, protecting
dune and swale habitat, and managing for appropriate levels and types
of disturbance.
Criteria Used To Identify Critical Habitat
As required by section 4(b)(1)(A) of the Act, we use the best
scientific and commercial data available to designate critical habitat.
We review available information pertaining to the habitat requirements
of the species. In accordance with the Act and its implementing
regulation at 50 CFR 424.12(e), we consider whether designating
additional areas--outside those currently occupied as well as those
occupied at the time of listing--are necessary to ensure the
conservation of the species. We are proposing to designate critical
habitat concurrent with listing in areas within the geographical area
occupied by the species.
We are proposing to designate all currently occupied habitat as
critical habitat--any degradation of existing occupied habitat would
further increase CPSD tiger beetle's susceptibility to extinction. CPSD
tiger beetle primarily occurs in two populations that are separated by
4.8 km (3 mi) of dunes. We include the 4.8-km (3-mi) dune segment that
separates the two populations because dispersal is likely important for
the long term-survival of the species (see Habitat, above), and this
central dune segment is used by dispersing adults. Comprehensive
surveys have not been conducted in this area for 20 years, and we have
no information to confirm the present occurrence of larval CPSD tiger
beetles and swale habitat.
We delineated the critical habitat unit boundaries for CPSD tiger
beetle using the following steps:
(1) In determining what areas were occupied by CPSD tiger beetle,
we used data collected by Dr. Barry Knisley (Hill and Knisley 1993 pp.
7-10; Knisley and Hill 1994 pp. 5-10; Knisley and Gowan 2005, pp. 7-8;
Knisley and Gowan 2011 p. 29) to map the central and northern
populations of CPSD tiger beetle using ArcMap 9.3.1.
(2) We delineated proposed critical habitat areas by creating
polygons around each population. Because of the narrowness of the
actual CPSD area (less than 1.6 km (1 mi)) and the shifting and
movement of habitat within the CPSD system, we included the entire
width of the CPSD area surrounding each population.
(3) We then included a dispersal corridor, the dune area between
the central and northern populations. We delineated the dispersal
corridor as the entirety of the dune area between the central and
northern populations because the entirety of the dune area could be
used by dispersing adults.
When determining proposed critical habitat boundaries, we made
every effort to avoid including developed areas such as lands covered
by buildings, pavement, and other structures because such lands lack
physical or biological features for CPSD tiger beetle. The scale of the
maps we prepared under the parameters for publication within the Code
of Federal Regulations may not reflect the exclusion of such developed
lands. Any such lands inadvertently left inside critical habitat
boundaries shown on the maps of this proposed rule have been excluded
by text in the proposed rule and are not proposed for designation as
critical habitat. Therefore, if the critical habitat is finalized as
proposed, a Federal action involving these lands would not trigger
section 7 consultation with respect to critical habitat and the
requirement of no adverse modification unless the specific action would
affect the physical or biological features in the adjacent critical
habitat.
We are proposing for designation of critical habitat lands that we
have determined are occupied at the time of listing and contain
sufficient elements of physical or biological features to support life-
history processes essential for the conservation of the CPSD tiger
beetle.
One unit is proposed for designation based on sufficient elements
of physical or biological features being present to support CPSD tiger
beetle life-history processes. This unit contains all of the identified
elements of physical or biological features and supports multiple life-
history processes.
Proposed Critical Habitat Designation
We are proposing one unit as critical habitat for CPSD tiger
beetle. The critical habitat area we describe below constitutes our
current best assessment of the area that meets the definition of
critical habitat for CPSD tiger beetle. The unit will be occupied at
the time of any listing and is currently occupied. The approximate area
of the proposed critical habitat unit is shown in Table 2.

boundaries]

------------------------------------------------------------------------
Note: Area sizes may not sum due to rounding.
We present brief descriptions of the unit, and reasons why it meets
the definition of critical habitat for CPSD tiger beetle, below.
CPSD Unit
The Unit consists of 921 ha (2,276 ac) of dune habitat and is
located entirely within the CPSD geologic feature (see Proposed
Regulation Promulgation, below). The southern 310 ha (767 acres) are
located within CPSD State Park. The northern 610 ha (1,508 ac) are
located on BLM land.
CPSD State Park is categorized as public land with a recreational
emphasis. The State Park encompasses the southern 809 ha (2,000 ac) of
the CPSD geologic feature. The habitat consists of a series of high,
mostly barren, dry dune ridges separated by lower, moister, and more
vegetated interdunal swales (Romey and Knisley 2002, p. 170). The
proposed unit overlaps an existing 84 ha (207 ac) of State Park
nonmotorized area (Conservation Area A). The remaining 227 ha (560 ac)
of the State Park are open to ORV use.
The BLM Kanab Resource Area manages the northern 610 ha (1,508 ac)
of the CPSD geologic feature (BLM 2000, p. 14). The BLM portion of the
proposed Unit is characterized by dunes and swales that contain dense
pockets of vegetation. In general, dunes and swales
[[Page 60229]]
in this unit are more stable and more highly vegetated than those in
the State Park (Ford et al. 2010, pp. 387-392). The proposed unit
overlaps an existing 150 ha (370 ac) of BLM nonmotorized area
(Conservation Area B). The remaining 460 ha (1,138 ac) of BLM land are
open to ORV use.
This unit currently has all the physical and biological features
essential to the conservation of the species. This unit requires
special management considerations or protections from the threats of
ORV use, drought, and climate change. It is located within the
appropriate elevation range, and it contains numerous moist and
vegetated swales near dunes. Adult and larval CPSD tiger beetle have
occurred throughout the proposed State Park owned portion of the Unit
continuously for the past 20 years (Knisley and Gowan 2011, p. 8), and
small numbers of adult and larval CPSD tiger beetles occupy the
northern extent within the BLM Conservation Area B habitat (Knisley and
Gowan 2011, p. 9). The central portion of the proposed unit between
Conservation Areas A and B may contain suitable swale habitat and
larval beetles; however, comprehensive surveys have not been conducted
in the past 20 years, and we have no information to confirm the present
occurrence of larval CPSD tiger beetles. However, the central portion
of the proposed unit is used by dispersing adult beetles, and likely
serves as a link between the two known populations.
Areas Outside Proposed Critical Habitat
As stated previously, we recognize that critical habitat designated
at a particular point in time may not include all of the habitat areas
that we may later determine are necessary for the recovery of the
species. For these reasons, a critical habitat designation does not
signal that habitat outside the designated area is unimportant or may
not be needed for recovery of the species.
Only areas within the historical distribution of CPSD tiger beetle
were considered for proposed critical habitat because areas outside of
the historical distribution do not contain the requisite PCEs for the
species. For this reason, we did not consider unoccupied areas outside
of the CPSD geologic feature.
We did consider the 227 ha (560 ac) of sand dunes within CPSD State
Park that exist south of our proposed critical habitat unit (see Figure
4 below). However, we have no information suggesting that this dune
area was historical habitat, or is now suitable habitat for CPSD tiger
beetle. Unlike the areas included within the proposed critical habitat
unit, this southern area has no record of CPSD tiger beetle larval
presence nor is there record of regular adult occurrence. As we
described previously (see Habitat), wind action in the dunes primarily
blows from south to north, and wind velocity decreases as it moves
across the sand dunes (from south to north). This results in a dynamic
and less vegetated south Dune area that transitions to a less dynamic
and more heavily vegetated and higher northern Dune area (Ford et al.
2010, pp. 387-392). The dynamic southern area has less vegetation cover
(Ford et al. 2010, pp. 387-392) and the high wind energy likely reduces
soil moisture levels (e.g., Lortie and Cushman 2007, pp. 478-479). We
believe the lack of PCEs (vegetative cover and appropriate soil
moisture) make the south Dune area unsuitable as critical habitat (see
Factor A for a discussion of the importance of soil moisture and
vegetation).
Effects of Critical Habitat Designation
Section 7 Consultation
Section 7(a)(2) of the Act requires Federal agencies, including the
Service, to ensure that any action they fund, authorize, or carry out
is not likely to jeopardize the continued existence of any endangered
species or threatened species or result in the destruction or adverse
modification of designated critical habitat of such species. In
addition, section 7(a)(4) of the Act requires Federal agencies to
confer with the Service on any agency action that is likely to
jeopardize the continued existence of any species proposed to be listed
under the Act or result in the destruction or adverse modification of
proposed critical habitat.
Decisions by the 5th and 9th Circuit Courts of Appeals have
invalidated our regulatory definition of ``destruction or adverse
modification'' (50 CFR 402.02) (see Gifford Pinchot Task Force v. U.S.
Fish and Wildlife Service, 378 F.3d 1059 (9th Cir. 2004) and Sierra
Club v. U.S. Fish and Wildlife Service et al., 245 F.3d 434, 442 (5th
Cir. 2001)), and we do not rely on this regulatory definition when
analyzing whether an action is likely to destroy or adversely modify
critical habitat. Under the statutory provisions of the Act, we
determine destruction or adverse modification on the basis of whether,
with implementation of the proposed Federal action, the affected
critical habitat would continue to serve its intended conservation role
for the species.
If a Federal action may affect a listed species or its critical
habitat, the responsible Federal agency (action agency) must enter into
consultation with us. Examples of actions that are subject to the
section 7 consultation process are actions on State, Tribal, local, or
private lands that require a Federal permit (such as a permit from the
U.S. Army Corps of Engineers under section 404 of the Clean Water Act
(33 U.S.C. 1251 et seq.) or a permit from the Service under section 10
of the Act) or that involve some other Federal action (such as funding
from the Federal Highway Administration, Federal Aviation
Administration, or the Federal Emergency Management Agency). Federal
actions not affecting listed species or critical habitat, and actions
on State, Tribal, local, or private lands that are not federally funded
or authorized, do not require section 7 consultation.
As a result of section 7 consultation, we document compliance with
the requirements of section 7(a)(2) through our issuance of:
(1) A concurrence letter for Federal actions that may affect, but
are not likely to adversely affect, listed species or critical habitat;
or
(2) A biological opinion for Federal actions that may affect, or
are likely to adversely affect, listed species or critical habitat.
When we issue a biological opinion concluding that a project is
likely to jeopardize the continued existence of a listed species and/or
destroy or adversely modify critical habitat, we provide reasonable and
prudent alternatives to the project, if any are identifiable, that
would avoid the likelihood of jeopardy and/or destruction or adverse
modification of critical habitat. We define ``reasonable and prudent
alternatives'' (at 50 CFR 402.02) as alternative actions identified
during consultation that:
(1) Can be implemented in a manner consistent with the intended
purpose of the action;
(2) Can be implemented consistent with the scope of the Federal
agency's legal authority and jurisdiction;
(3) Are economically and technologically feasible; and
(4) Would, in the Director's opinion, avoid the likelihood of
jeopardizing the continued existence of the listed species and/or avoid
the likelihood of destroying or adversely modifying critical habitat.
Reasonable and prudent alternatives can vary from slight project
modifications to extensive redesign or relocation of the project. Costs
associated with implementing a reasonable and prudent alternative are
similarly variable.
[[Page 60230]]
Regulations at 50 CFR 402.16 require Federal agencies to reinitiate
consultation on previously reviewed actions in instances where we have
listed a new species or subsequently designated critical habitat that
may be affected and the Federal agency has retained discretionary
involvement or control over the action (or the agency's discretionary
involvement or control is authorized by law). Consequently, Federal
agencies sometimes may need to request reinitiation of consultation
with us on actions for which formal consultation has been completed, if
those actions with discretionary involvement or control may affect
subsequently listed species or designated critical habitat.
Application of the ``Adverse Modification'' Standard
The key factor related to the adverse modification determination is
whether, with implementation of the proposed Federal action, the
affected critical habitat would continue to serve its intended
conservation role for the species. Activities that may destroy or
adversely modify critical habitat are those that alter the physical or
biological features to an extent that appreciably reduces the
conservation value of critical habitat for CPSD tiger beetle. As
discussed above, the role of critical habitat is to support life-
history needs of the species and provide for the conservation of the
species.
Section 4(b)(8) of the Act requires us to briefly evaluate and
describe, in any proposed or final regulation that designates critical
habitat, activities involving a Federal action that may destroy or
adversely modify such habitat, or that may be affected by such
designation.
Activities that may affect critical habitat, when carried out,
funded, or authorized by a Federal agency, should result in
consultation for the CPSD tiger beetle. These activities include, but
are not limited to:
(1) Actions that would reduce soil moisture or vegetative cover in
swale habitats. Such activities could include, but are not limited to,
continued or increased vehicular access or pedestrian traffic in or
adjacent to occupied habitats. These activities could reduce soil
moisture by churning up soils and exposing the moisture that is locked
up between soil particles (beneath the surface) to greater evaporative
pressure (Shultz 1988, p. 28) and by increasing soil compaction (Adams
et al. 1982, p. 167). These activities also could reduce vegetative
cover by trampling and subsequently injuring or killing plants.
Reduced soil moisture may lead to death of some CPSD tiger beetle
larvae, as soil moisture is the most important factor determining
larval tiger beetle survival (Knisley and Juliano 1988, entire).
Reduced vegetative cover adversely impacts CPSD tiger beetle
ovipositioning, adult thermoregulation, and prey base. Low prey
densities can result in prolonged development and decreased
survivorship in larval tiger beetles and reduced size in adults, which
lowers fecundity in females (Pearson and Knisley 1985, p. 165; Knisley
and Juliano 1988, p. 1990).
(2) Actions that would significantly affect dune morphology or
dynamics. Such activities could include road or campground construction
within or adjacent to the dunes. CPSD is a dynamic system where wind
action continues to shape the dunes and redistribute sediment. Any
significant alteration to dune morphology or dynamics may alter the
arrangement and amount of swale and dune habitat available to CPSD
tiger beetle.
Exemptions
Application of Section 4(a)(3) of the Act
The Sikes Act Improvement Act of 1997 (Sikes Act) (16 U.S.C. 670a)
required each military installation that includes land and water
suitable for the conservation and management of natural resources to
complete an integrated natural resources management plan (INRMP) by
November 17, 2001. An INRMP integrates implementation of the military
mission of the installation with stewardship of the natural resources
found on the base. Each INRMP includes:
(1) An assessment of the ecological needs on the installation,
including the need to provide for the conservation of listed species;
(2) A statement of goals and priorities;
(3) A detailed description of management actions to be implemented
to provide for these ecological needs; and
(4) A monitoring and adaptive management plan.
Among other things, each INRMP must, to the extent appropriate and
applicable, provide for fish and wildlife management; fish and wildlife
habitat enhancement or modification; wetland protection, enhancement,
and restoration where necessary to support fish and wildlife; and
enforcement of applicable natural resource laws.
The National Defense Authorization Act for Fiscal Year 2004 (Pub.
L. 108-136) amended the Act to limit areas eligible for designation as
critical habitat. Specifically, section 4(a)(3)(B)(i) of the Act (16
U.S.C. 1533(a)(3)(B)(i)) now provides: ``The Secretary shall not
designate as critical habitat any lands or other geographical areas
owned or controlled by the Department of Defense, or designated for its
use, that are subject to an integrated natural resources management
plan prepared under section 101 of the Sikes Act (16 U.S.C. 670a), if
the Secretary determines in writing that such plan provides a benefit
to the species for which critical habitat is proposed for
designation.''
There are no Department of Defense lands within the proposed
critical habitat designation. Thus, we are not proposing any exemptions
based on section 4(a)(3)(B)(i).
Exclusions
Application of Section 4(b)(2) of the Act
Section 4(b)(2) of the Act states that the Secretary shall
designate and make revisions to critical habitat on the basis of the
best available scientific data after taking into consideration the
economic impact, national security impact, and any other relevant
impact of specifying any particular area as critical habitat. The
Secretary may exclude an area from critical habitat if he determines
that the benefits of such exclusion outweigh the benefits of specifying
such area as part of the critical habitat, unless he determines, based
on the best scientific data available, that the failure to designate
such area as critical habitat will result in the extinction of the
species. In making that determination, the statute on its face, as well
as the legislative history, are clear that the Secretary has broad
discretion regarding which factor(s) to use and how much weight to give
to any factor.
Under section 4(b)(2) of the Act, we may exclude an area from
designated critical habitat based on economic impacts, impacts on
national security, or any other relevant impacts. In considering
whether to exclude a particular area from the designation, we identify
the benefits of including the area in the designation, identify the
benefits of excluding the area from the designation, and evaluate
whether the benefits of exclusion outweigh the benefits of inclusion.
If the analysis indicates that the benefits of exclusion outweigh the
benefits of inclusion, the Secretary may exercise his discretion to
exclude the area only if such exclusion would not result in the
extinction of the species.
Exclusions Based on Economic Impacts
Under section 4(b)(2) of the Act, we consider the economic impacts
of
[[Page 60231]]
specifying any particular area as critical habitat. In order to
consider economic impacts, we are preparing an analysis of the economic
impacts of the proposed critical habitat designation and related
factors.
Upon completion, copies of the draft economic analysis will be
available for downloading from the Internet at https://www.regulations.gov, or by contacting the Utah Fish and Wildlife Office
directly (see FOR FURTHER INFORMATION CONTACT section). During the
development of a final designation, we will consider economic impacts,
public comments, and other new information. Areas may be excluded from
the final critical habitat designation under section 4(b)(2) of the Act
and our implementing regulations at 50 CFR 424.19.
Exclusions Based on National Security Impacts
Under section 4(b)(2) of the Act, we consider whether there are
lands owned or managed by the Department of Defense where a national
security impact might exist.
In preparing this proposal, we have determined that the lands
within the proposed designation of critical habitat for CPSD tiger
beetle are not owned or managed by the Department of Defense, and,
therefore, we anticipate no impact on national security. Consequently,
the Secretary does not propose to exercise his discretion to exclude
any areas from the final designation based on impacts on national
security.
Exclusions Based on Other Relevant Impacts
Under section 4(b)(2) of the Act, we consider any other relevant
impacts, in addition to economic impacts and impacts on national
security. We consider a number of factors, including whether the
landowners have developed any HCPs or other management plans for the
area, or whether there are conservation partnerships that would be
encouraged by designation of, or exclusion from, critical habitat. In
addition, we look at any Tribal issues, and consider the government-to-
government relationship of the United States with Tribal entities. We
also consider any social impacts that might occur because of the
designation.
In preparing this proposal, we have determined that there are
currently no HCPs for CPSD tiger beetle, and the proposed designation
does not include any Tribal lands or trust resources. We anticipate no
impact on Tribal lands, partnerships, or HCPs from this proposed
critical habitat designation. As we described previously, a CCA exists
for CPSD tiger beetle (see Factor A and D). However, we determined in
Factor A and D that this agreement is not adequately reducing threats
to the species. Accordingly, the Secretary does not propose to exercise
his discretion to exclude any areas from the final designation based on
other relevant impacts.
Peer Review
In accordance with our joint policy on peer review published in the
Federal Register on July 1, 1994 (59 FR 34270), we will seek the expert
opinions of at least three appropriate and independent specialists
regarding this proposed rule. The purpose of peer review is to ensure
that our listing and critical habitat designation is based on
scientifically sound data, assumptions, and analyses. We have invited
these peer reviewers to comment during this public comment period on
this proposed rule to list the species as threatened and the
designation of critical habitat.
We will consider all comments and information received during this
comment period on this proposed rule during our preparation of a final
determination. Accordingly, the final decision may differ from this
proposal.
Public Hearings
Section 4(b)(5) of the Act provides for one or more public hearings
on this proposal, if requested. Requests must be received within 45
days after the date of publication of this proposed rule in the Federal
Register. Such requests must be sent to the address shown in FOR
FURTHER INFORMATION CONTACT. We will schedule public hearings on this
proposal, if any are requested, and announce the dates, times, and
places of those hearings, as well as how to obtain reasonable
accommodations, in the Federal Register and local newspapers at least
15 days before the hearing.
Required Determinations
Regulatory Planning and Review--Executive Orders 12866 and 13563
Executive Order 12866 provides that the Office of Information and
Regulatory Affairs (OIRA) in the Office of Management and Budget will
review all significant rules. The Office of Information and Regulatory
Affairs has determined that this rule is not significant.
Executive Order 13563 reaffirms the principles of E.O. 12866 while
calling for improvements in the nation's regulatory system to promote
predictability, to reduce uncertainty, and to use the best, most
innovative, and least burdensome tools for achieving regulatory ends.
The executive order directs agencies to consider regulatory approaches
that reduce burdens and maintain flexibility and freedom of choice for
the public where these approaches are relevant, feasible, and
consistent with regulatory objectives. E.O. 13563 emphasizes further
that regulations must be based on the best available science and that
the rulemaking process must allow for public participation and an open
exchange of ideas. We have developed this rule in a manner consistent
with these requirements.
Regulatory Flexibility Act (5 U.S.C. 601 et seq.)
Under the Regulatory Flexibility Act (RFA) (5 U.S.C. 601 et seq.)
as amended by the Small Business Regulatory Enforcement Fairness Act
(SBREFA) of 1996 (5 U.S.C. 801 et seq.), whenever an agency must
publish a notice of rulemaking for any proposed or final rule, it must
prepare and make available for public comment a regulatory flexibility
analysis that describes the effects of the rule on small entities
(small businesses, small organizations, and small government
jurisdictions). However, no regulatory flexibility analysis is required
if the head of the agency certifies the rule will not have a
significant economic impact on a substantial number of small entities.
The SBREFA amended the RFA to require Federal agencies to provide a
certification statement of the factual basis for certifying that the
rule will not have a significant economic impact on a substantial
number of small entities.
At this time, we lack the available economic information necessary
to provide an adequate factual basis for the required RFA finding.
Therefore, we defer the RFA finding until completion of the draft
economic analysis. This draft economic analysis will provide the
required factual basis for the RFA finding. Upon completion of the
draft economic analysis, we will announce availability of the draft
economic analysis of the proposed designation in the Federal Register
and reopen the public comment period for the proposed designation. We
will include with this announcement, as appropriate, an initial
regulatory flexibility analysis or a certification that the rule will
not have a significant economic impact on a substantial number of small
entities accompanied by the factual basis for that determination.
Land use sectors that could be affected by this proposed rule
include: BLM land managers, CPSD State Park land managers, and ORV
users that may
[[Page 60232]]
be or are utilizing the proposed critical habitat unit.
We have concluded that deferring the RFA finding until completion
of the draft economic analysis is necessary to meet the purposes and
requirements of the RFA. Deferring the RFA finding in this manner will
ensure that we make a sufficiently informed determination based on
adequate economic information and provide the necessary opportunity for
public comment.
Energy Supply, Distribution, or Use--Executive Order 13211
Executive Order 13211 (Actions Concerning Regulations That
Significantly Affect Energy Supply, Distribution, or Use) requires
agencies to prepare Statements of Energy Effects when undertaking
certain actions. We do not expect the designation of this proposed
critical habitat to significantly affect energy supplies, distribution,
or use as there is no energy supply or distribution infrastructure near
the proposed critical habitat. Therefore, this action is not a
significant energy action, and no Statement of Energy Effects is
required. However, we will further evaluate this issue as we conduct
our economic analysis, and review and revise this assessment as
warranted.
Unfunded Mandates Reform Act (2 U.S.C. 1501 et seq.)
In accordance with the Unfunded Mandates Reform Act (2 U.S.C. 1501
et seq.), we make the following findings:
(1) This rule will not produce a Federal mandate. In general, a
Federal mandate is a provision in legislation, statute, or regulation
that would impose an enforceable duty upon State, local, or Tribal
governments, or the private sector, and includes both ``Federal
intergovernmental mandates'' and ``Federal private sector mandates.''
These terms are defined in 2 U.S.C. 658(5)-(7). ``Federal
intergovernmental mandate'' includes a regulation that ``would impose
an enforceable duty upon State, local, or tribal governments'' with two
exceptions. It excludes ``a condition of Federal assistance.'' It also
excludes ``a duty arising from participation in a voluntary Federal
program,'' unless the regulation ``relates to a then-existing Federal
program under which $500,000,000 or more is provided annually to State,
local, and tribal governments under entitlement authority,'' if the
provision would ``increase the stringency of conditions of assistance''
or ``place caps upon, or otherwise decrease, the Federal Government's
responsibility to provide funding,'' and the State, local, or Tribal
governments ``lack authority'' to adjust accordingly. At the time of
enactment, these entitlement programs were: Medicaid; Aid to Families
with Dependent Children work programs; Child Nutrition; Food Stamps;
Social Services Block Grants; Vocational Rehabilitation State Grants;
Foster Care, Adoption Assistance, and Independent Living; Family
Support Welfare Services; and Child Support Enforcement. ``Federal
private sector mandate'' includes a regulation that ``would impose an
enforceable duty upon the private sector, except (i) a condition of
Federal assistance or (ii) a duty arising from participation in a
voluntary Federal program.''
The designation of critical habitat does not impose a legally
binding duty on non-Federal Government entities or private parties.
Under the Act, the only regulatory effect is that Federal agencies must
ensure that their actions do not destroy or adversely modify critical
habitat under section 7. While non-Federal entities that receive
Federal funding, assistance, or permits, or that otherwise require
approval or authorization from a Federal agency for an action, may be
indirectly impacted by the designation of critical habitat, the legally
binding duty to avoid destruction or adverse modification of critical
habitat rests squarely on the Federal agency. Furthermore, to the
extent that non-Federal entities are indirectly impacted because they
receive Federal assistance or participate in a voluntary Federal aid
program, the Unfunded Mandates Reform Act would not apply, nor would
critical habitat shift the costs of the large entitlement programs
listed above onto State governments.
(2) We do not believe that this rule will significantly or uniquely
affect small governments because the lands being proposed for critical
habitat designation are owned by the State of Utah, and the BLM. None
of these government entities fit the definition of ``small governmental
jurisdiction.'' Therefore, a Small Government Agency Plan is not
required. However, we will further evaluate this issue as we conduct
our economic analysis, and review and revise this assessment as
warranted.
Takings--Executive Order 12630
In accordance with Executive Order 12630 (Government Actions and
Interference with Constitutionally Protected Private Property Rights),
we have analyzed the potential takings implications of designating
critical habitat for CPSD tiger beetle in a takings implications
assessment. Critical habitat designation does not affect landowner
actions that do not require Federal funding or permits, nor does it
preclude development of habitat conservation programs or issuance of
incidental take permits to permit actions that do require Federal
funding or permits to go forward. The takings implications assessment
concludes that this designation of critical habitat for CPSD tiger
beetle does not pose significant takings implications for lands within
or affected by the designation.
Federalism--Executive Order 13132
In accordance with Executive Order 13132 (Federalism), this
proposed rule does not have significant Federalism effects. A
Federalism assessment is not required. In keeping with Department of
the Interior and Department of Commerce policy, we requested
information from, and coordinated development of this proposed critical
habitat designation with, appropriate State resource agencies in Utah.
The designation of critical habitat in areas currently occupied by CPSD
tiger beetle may impose nominal additional regulatory restrictions to
those currently in place and, therefore, may have little incremental
impact on State and local governments and their activities. The
designation may have some benefit to these governments because the
areas that contain the physical or biological features essential to the
conservation of the species are more clearly defined, and the elements
of the features of the habitat necessary to the conservation of the
species are specifically identified. This information does not alter
where and what federally sponsored activities may occur. However, it
may assist local governments in long-range planning (rather than having
them wait for case-by-case section 7 consultations to occur).
Where State and local governments require approval or authorization
from a Federal agency for actions that may affect critical habitat,
consultation under section 7(a)(2) would be required. While non-Federal
entities that receive Federal funding, assistance, or permits, or that
otherwise require approval or authorization from a Federal agency for
an action, may be indirectly impacted by the designation of critical
habitat, the legally binding duty to avoid destruction or adverse
modification of critical habitat rests squarely on the Federal agency.
Civil Justice Reform--Executive Order 12988
In accordance with Executive Order 12988 (Civil Justice Reform),
the Office of the Solicitor has determined that the rule does not
unduly burden the judicial
[[Page 60233]]
system and that it meets the requirements of sections 3(a) and 3(b)(2)
of the Order. We have proposed designating critical habitat in
accordance with the provisions of the Act. This proposed rule uses
standard property descriptions and identifies the elements of physical
or biological features essential to the conservation of the CPSD tiger
beetle within the designated areas to assist the public in
understanding the habitat needs of the species.
Paperwork Reduction Act of 1995 (44 U.S.C. 3501 et seq.)
This rule does not contain any new collections of information that
require approval by OMB under the Paperwork Reduction Act of 1995 (44
U.S.C. 3501 et seq.). This rule will not impose recordkeeping or
reporting requirements on State or local governments, individuals,
businesses, or organizations. An agency may not conduct or sponsor, and
a person is not required to respond to, a collection of information
unless it displays a currently valid OMB control number.
National Environmental Policy Act (42 U.S.C. 4321 et seq.)
It is our position that, outside the jurisdiction of the U.S. Court
of Appeals for the Tenth Circuit, we do not need to prepare
environmental analyses pursuant to the NEPA (42 U.S.C. 4321 et seq.) in
connection with designating critical habitat under the Act. We
published a notice outlining our reasons for this determination in the
Federal Register on October 25, 1983 (48 FR 49244). This position was
upheld by the U.S. Court of Appeals for the Ninth Circuit (Douglas
County v. Babbitt, 48 F.3d 1495 (9th Cir. 1995), cert. denied 516 U.S.
1042 (1996)).
However, when the range of the species includes States within the
Tenth Circuit, such as that of CPSD tiger beetle, under the Tenth
Circuit ruling in Catron County Board of Commissioners v. U.S. Fish and
Wildlife Service, 75 F.3d 1429 (10th Cir. 1996), we will undertake a
NEPA analysis for critical habitat designation and notify the public of
the availability of the draft environmental assessment for this
proposal when it is finished.
Government-to-Government Relationship With Tribes
In accordance with the President's memorandum of April 29, 1994
(Government-to-Government Relations with Native American Tribal
Governments; 59 FR 22951), Executive Order 13175 (Consultation and
Coordination With Indian Tribal Governments), and the Department of the
Interior's manual at 512 DM 2, we readily acknowledge our
responsibility to communicate meaningfully with recognized Federal
Tribes on a government-to-government basis. In accordance with
Secretarial Order 3206 of June 5, 1997 (American Indian Tribal Rights,
Federal-Tribal Trust Responsibilities, and the Act), we readily
acknowledge our responsibilities to work directly with Tribes in
developing programs for healthy ecosystems, to acknowledge that Tribal
lands are not subject to the same controls as Federal public lands, to
remain sensitive to Indian culture, and to make information available
to Tribes.
We determined that there are no Tribal lands that were occupied by
CPSD tiger beetle at the time of listing that contain the features
essential for conservation of the species, and no Tribal lands
unoccupied by the CPSD tiger beetle that are essential for the
conservation of the species. Therefore, we are not proposing to
designate critical habitat for CPSD tiger beetle on Tribal lands.
Clarity of the Rule
We are required by Executive Orders 12866 and 12988 and by the
Presidential Memorandum of June 1, 1998, to write all rules in plain
language. This means that each rule we publish must:
(1) Be logically organized;
(2) Use the active voice to address readers directly;
(3) Use clear language rather than jargon;
(4) Be divided into short sections and sentences; and
(5) Use lists and tables wherever possible.
If you feel that we have not met these requirements, send us
comments by one of the methods listed in the ADDRESSES section. To
better help us revise the rule, your comments should be as specific as
possible. For example, you should tell us the numbers of the sections
or paragraphs that are unclearly written, which sections or sentences
are too long, the sections where you feel lists or tables would be
useful, etc.

Coral Pink Sand Dunes Tiger Beetle (Cicindela albissima)
(1) A single critical habitat unit is depicted for Kane County,
Utah on the map below.
(2) Within this area, the primary constituent elements of the
physical or biological features essential to the conservation of the
Coral Pink Sand Dunes tiger beetle consist of:
(i) Dynamic sand dunes and swales within the Coral Pink Sand Dunes
geologic feature that have:
(A) Elevations from 1,710 to 2,090 m;
(B) Appropriate levels of moisture and compaction to allow for
burrowing (greater than 3 percent); and
(C) Vegetative cover of 23-57 percent that allows for ovipositing,
adult thermoregulation, and abundant prey.
(3) Critical habitat does not include manmade structures (such as
buildings, aqueducts, runways, roads, and other paved areas) and the
land on which they are located existing within the legal boundaries on
the effective date of this rule.
(4) Critical habitat map unit. Data layers defining the map unit
were created on a base of both satellite imagery (NAIP 2009) as well as
USGS geospatial quadrangle maps and were mapped using NAD 83 Universal
Transverse Mercator (UTM), zone 13N coordinates. Location information
came from a wide array of sources. The maps in this entry, as modified
by any accompanying regulatory text, establish the boundaries of the
critical habitat designation. The coordinates or plot points or both on
which the map is based are available to the public at the Service's
internet site, https://www.fws.gov/utahfieldoffice/, at https://www.regulations.gov in Docket No. FWS-R6-ES-2012-0053 and at the field
office responsible for the designation. You may obtain field office
location information by contacting one of the Service regional offices,
the addresses of which are listed at 50 CFR 2.2.
