[Docket No. FWS-R5-ES-2012-0054; 4500030113]

Endangered and Threatened Wildlife and Plants; 90-Day Finding on
a Petition to List the Heller Cave Springtail as Endangered or
Threatened

AGENCY: Fish and Wildlife Service, Interior.

ACTION: Notice of petition finding and initiation of status review.

-----------------------------------------------------------------------

SUMMARY: We, the U.S. Fish and Wildlife Service (Service), announce a
90-day finding on a petition to list the Heller Cave springtail as
endangered or threatened under the Endangered Species Act of 1973, as
amended (Act) and to designate critical habitat. Based on our review,
we find that the petition presents substantial scientific or commercial
information indicating that listing this species may be warranted.
Therefore, with the publication of this notice, we are initiating a
review of the status of the species to determine if listing the Heller
Cave springtail is warranted. To ensure that this status review is
comprehensive, we are requesting scientific and commercial data and
other information regarding this species. Based on the status review,
we will issue a 12-month finding on the petition, which will address
whether the petitioned action is warranted, as provided in section
4(b)(3)(B) of the Act.

DATES: We request that we receive information on or before January 14,
2013. The deadline for submitting an electronic comment using the
Federal eRulemaking Portal (see ADDRESSES section below) is 11:59 p.m.
Eastern Time on this date. After January 14, 2013, you must submit
information directly to the Division of Policy and Directives
Management (see ADDRESSES section below). Please note that we might not
be able to address or incorporate information that we receive after the
above requested date.

SUPPLEMENTARY INFORMATION:

Request for Information

When we make a finding that a petition presents substantial
information indicating that listing a species may be warranted, we are
required to promptly initiate review of the status of the species
(status review). For the status review to be complete and based on the
best available scientific and commercial information, we request
information on the Heller Cave springtail (Typhlogastrura helleri) from
governmental agencies, Native American tribes, the scientific
community, industry, and any other interested parties. We seek
information on:
(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 survey data and
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) Information related to the operation and status of the small,
large, or both, non-coal mining project(s) and permit(s) associated
with the ``Carlim Quarry'' or ``Catherine Properties-Heller Mine'' in
Catherine Township, Blair County, Pennsylvania. The owner or operator
of this project may be known as Gulf Trading and Transport, Catherine
Corporation, or General Trade Corporation.
If, after the status review, we determine that listing the Heller
Cave springtail is warranted, we will propose critical habitat (see
definition in section 3(5)(A) of the Act) under section 4 of the Act,
to the maximum extent prudent and determinable at the time we propose
to list the species. Therefore, we also request data and information
on:
(1) What may constitute ``physical or biological features essential
to the conservation of the species,'' within the geographical range
currently occupied by the species;
(2) Where these features are currently found;
(3) Whether any of these features may require special management
considerations or protection;
(4) Specific areas outside the geographical area occupied by the
species that are ``essential for the conservation of the species;'' and
(5) What, if any, critical habitat you think we should propose for
designation if the species is proposed for listing, and why such
habitat meets the requirements of section 4 of the Act.
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.
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. 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 information concerning this status review by
one of the methods listed in the ADDRESSES section. If you submit
information via http://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 personal identifying information from
public review. However, we cannot guarantee that we will be able to do
so. We will post all hardcopy submissions on http://www.regulations.gov.
Information and supporting documentation that we received and used
in preparing this finding is available for you to review at http://www.regulations.gov, or by appointment, during normal business hours,
at the U.S. Fish and Wildlife Service, Northeast Regional Office (see
FOR FURTHER INFORMATION CONTACT).

Background

Section 4(b)(3)(A) of the Act requires that we make a finding on
whether a petition to list, delist, or reclassify a species presents
substantial scientific or commercial information indicating that the
petitioned action may be warranted. We are to base this finding on
information provided in the petition, supporting information submitted
with the petition, and information otherwise available in our files at
the time of the petition's receipt. To the maximum extent practicable,
we are to make this finding within 90 days of our receipt of the
petition and publish our notice of the finding promptly in the Federal
Register.
Our standard for substantial scientific or commercial information
within the Code of Federal Regulations (CFR) with regard to a 90-day
petition finding is ``that amount of information that would lead a
reasonable person to believe that the measure proposed in the petition
may be warranted'' (50 CFR 424.14(b)). If we find that substantial
scientific or commercial information was presented, we are required to
promptly initiate a species status review, which we subsequently
summarize in our 12-month finding.

Petition History

On October 13, 2011, we received a petition dated October 13, 2011,
from Mollie Matteson (petitioner), on behalf of the Center for
Biological Diversity (CBD) and the Juniata Valley Audubon Society
(JVAS), requesting that the Heller Cave springtail be listed as
endangered and that critical habitat be designated under the Act
(Petition). The petition clearly identified itself as such and included
the requisite identification information for the petitioners, required
at 50 CFR 424.14(a). In a January 8, 2012, letter to the petitioner, we
responded that we had received the petition sent to the Secretary of
the Interior and that we would contact the petitioner when we completed
review of the petition. On January 11, 2012, the petitioner sent
additional information to supplement the October 13, 2011 petition.
This finding addresses the supplemented petition.

Previous Federal Actions

There are no previous Federal actions on the Heller Cave
springtail.

Species Information

The Heller Cave springtail is a small, wingless, cave-dwelling
arthropod in the Family Hypogastruridae and Order Collembola. All
Collembola have the common name of ``springtail'' because of their
furcula, or ``jumping apparatus''

[[Page 67786]]

located underneath and at the end of the abdomen (Christiansen 1992, p.
3). The Heller Cave springtail type specimen (individual used to
formally describe the species) is 1.4 millimeters (mm) (0.06 inches
(in)) long, but other specimens have ranged up to 2.1 mm (0.08 in) in
length (Christiansen and Wang 2006, p. 89). The Heller Cave springtail
is tan with five to six black eye spots on each side of its head and
three thoracic (chest) segments (Christiansen and Wang 2006, pp. 92-
94). A more detailed species' description can be found in Christiansen
and Wang (2006, pp. 92-94).
The petitioner, citing the scientist who first described the
species, asserts that the Heller Cave springtail is endemic to Heller
Cave in Huntingdon County, Pennsylvania (Petition, p. 5; Christiansen
and Wang 2006, p. 93). The type locality (location where the type
specimen was collected), Heller Cave 5, is one of nine caves
in a cave complex (Petition, p. 7) spanning the Blair-Huntingdon County
line. The type specimen was collected within the cave on a pool surface
(Christiansen and Wang 2006, p. 94). However, information in our files
suggests that it may not be reasonable to automatically assume the
species is solely endemic to Heller Cave. Discussion between Joseph
Reznik, a springtail expert from the Carnegie Museum of Natural
History, and Betsy Leppo, an invertebrate zoologist with the
Pennsylvania Natural Heritage Program (PNHP), indicates that there is
uncertainty about previous assumptions regarding the species' aquatic
nature and cave endemism (Leppo 2010, pp. 1-2). In an electronic mail
message to PNHP staff, the springtail expert stated ``Many species of
springtails that have been attributed to being cave endemics have been
classified being endemic based on physical characteristics (i.e., loss
of pigment, eyes, etc.), but many soil species also have these
characteristics,'' and suggested that Heller Cave springtail surveys be
conducted in the scree and talus environments outside of Heller Cave
(Leppo 2010, p. 2). We are unaware of whether PNHP or Pennsylvania Game
Commission (PGC) conducted further surveys for Heller Cave springtail
outside of the species' type locality.
We have no information about the Heller Cave springtail's habitat
outside of the type locality, diet, reproduction, or population size.
Inferring information from other springtails may not be fully reliable,
as some of these characteristics within the Collembola Order vary
widely. For example, Christiansen (1992, p. 2) states Collembola
``occur almost everywhere from the tops of the tallest trees to the
deepest soil strata where life occurs. They are in fact found
everywhere life of any sort is found except the open ocean or below
surface in bodies of freshwater.'' As for diet, some species eat plant
material, others eat micro-organisms, and some exhibit cannibalistic
traits and eat their own eggs (Christiansen 1992, p. 4; Bellenger et
al. 1996, pp. 2-3). In general, Collembola exhibit sexual
differentiation (male and female individuals), and reproduction occurs
through the deposition and reception of spermatophores (sperm packets);
eggs are laid; and molting occurs during growth (Christiansen 1992, pp.
4-5). Christiansen and Wang (2006, p. 93) did collect both male and
female individuals in Heller Cave 5. None of the readily
available information sources indicate what a typical population size
for Collembola species may be, and no typical population size is
available specifically for the Heller Cave springtail.
The species was formerly described by Christiansen and Wang (2006,
entire). We do not have any information in our files that indicates
controversy with the species' taxonomy; therefore, at this time we are
recognizing the Heller Cave springtail as a valid species.

Evaluation of Information for This Finding

Section 4 of the Act (16 U.S.C. 1533) and its implementing
regulations at 50 CFR 424 set forth the procedures for adding a species
to, or removing a species from, the Federal Lists of Endangered and
Threatened Wildlife and Plants. A species may be determined to be an
endangered or threatened species due to one or more of the five factors
described in section 4(a)(1) of the Act:
(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.
In considering what factors might constitute threats, we must look
beyond the mere exposure of the species to the factor to determine
whether the species responds to the factor in a way that causes actual
impacts to the species. If there is exposure to a factor, but no
response, or only a positive response, that factor is not a threat. If
there is exposure and the species responds negatively, the factor may
be a threat and we then attempt to determine how significant a threat
it is. If the threat is significant, it may drive or contribute to the
risk of extinction of the species such that the species may warrant
listing as endangered or threatened as those terms are defined by the
Act. This does not necessarily require empirical proof of a threat. The
combination of exposure and some corroborating evidence of how the
species is likely impacted could suffice. The mere identification of
factors that could impact a species negatively may not be sufficient to
compel a finding that listing may be warranted. The information shall
contain evidence sufficient to suggest that these factors may be
operative threats that act on the species to the point that the species
may meet the definition of threatened or endangered under the Act.
In making this 90-day finding, we evaluated whether information
regarding threats to the Heller Cave springtail, as presented in the
petition and other information available in our files is substantial,
thereby indicating that the petitioned action may be warranted. Our
evaluation of this information is presented below.
A. The Present or Threatened Destruction, Modification, or Curtailment
of Its Habitat or Range
Information Provided in the Petition
The petitioner states that a proposed limestone quarry in Blair
County, Pennsylvania, would significantly modify or destroy the Heller
Caves complex, the only known location of the Heller Cave springtail
(Petition, p. 10). The petitioner states that in June 2010, ``* * * the
Pennsylvania Department of Environmental Protection [DEP], Bureau of
Mining and Reclamation, issued a small non-coal mining permit to
Catherine Properties, LLC, for a project at and around the Heller Caves
site. This permit allows logging, road building, and removal of up to
10,000 tons per year of rock and other surface materials (Pennsylvania
DEP 2010a)'' (Petition, p. 10). The petitioner also states that ``even
if a quarry does not completely obliterate a cave, it can cause
significant harm to cave habitat in several ways,'' including
structural damage; changes in temperature, humidity, water quality, and
water quantity; and trampling of flora and fauna, littering, and
introduction of foreign substances through increased human access
(Petition, pp. 12-14). The petitioner asserts that these impacts are
particularly problematic for cave

[[Page 67787]]

obligate species like the Heller Cave springtail (Petition, p. 12).
Evaluation of Information Provided in the Petition and Available in
Service Files
The petitioner's assertion that the limestone quarry (i.e., mine)
proposed for operation in Blair County, Pennsylvania, near the Heller
Caves complex will remove a significant amount of rock, is corroborated
by readily available information within the Service's files (Secor
2006a, entire; Secor 2006b, entire; Service 2006, entire; Service 2009,
entire; Stormer 2009, entire; U.S. Department of Agriculture (USDA)
2010, entire; Stormer 2010a, entire; Stormer 2010b, entire). The amount
of total acreage of the proposed site varies from 5 to 187 acres (2 to
76 hectares (ha)), and the acreage and potential location of
disturbance varies from 5 to 7.4 acres (2 to 3 ha) inside or outside of
the Heller Caves core area, depending upon the source of the
information (Secor 2006a, p. 1; PADEP 2009, p. 1; Service 2009, p. 1;
Stormer 2009, p. 1; USDA 2010, pp. 1, 4; Stormer 2010a, p. 1; Stormer
2010b, p. 1; Turner 2010, p. 1; Petition, p. 11). We do not have
readily available copies of the permit request from Gulf Trading and
Transport (sometimes alternatively known as Catherine Properties or
General Trade Corporation) including the scope of, and specific
activities associated with, a small or large non-coal mining operation,
the approved permit from PADEP, or PGC's comments on the proposed
permit to be able to state the actual recorded site and disturbance
acreages.
We have limited information on the project's proposed impacts to
the area. We only have project information regarding the potential
size, county location, and land clearing (e.g., forestry) activities
provided to us when we conducted three separate project analyses for
potential impacts to the federally listed northeastern bulrush (Scirpus
ancistrochaetus) (Service 2006, p. 2) and the Indiana bat (Myotis
sodalis) (Service 2006, pp. 1-2; Service 2009, p. 1; Service 2010, pp.
1-2). Indiana bats are not found in the Heller Caves complex (Western
Pennsylvania Conservancy (WPC) 2006, entire; Turner 2010, p. 1). The
Service has jurisdiction over federally listed species, so our review
and analyses were conducted within that jurisdictional constraint. We
did not have information about, or recommendations for, either the
eastern small-footed bat or the Heller Cave springtail during the 2006,
2009, and 2010 project reviews.
Because we do not have readily available, project-specific
information about the proposed Heller Cave mine project beyond the
potential project size, county location, and impacts to Indiana bat
habitat from forestry clearing we used in the 2006, 2009, and 2010
reviews, we cannot assess the accuracy of the petitioner's mining
operation project details (Petition, pp. 10-12). If the petitioner's
information is correct about blasting activities being a part of the
small (or large) non-coal mining permit (Petition, p. 11), the
potential effects of the blasting activity may impact the Heller Cave
springtail. The Heller Caves complex is identified in a Blair County
planning document as core habitat for eastern small-footed bat (Myotis
leibii) winter hibernation (Western Pennsylvania Conservancy (WPC)
2006, p. 46). The Heller Cave springtail co-occurs in the Heller Cave
5 with the eastern small-footed bat. The Blair County planning
document states ``Blasting or other activities that disrupt bedrock
within the core areas may damage the structure of the cave, potentially
making it unsuitable for the bats,'' and recommends ``blasting and
other activities that will affect the bedrock should be avoided within
this [core habit] area so as not to damage the cave in use as a
hibernation site (WPC 2006, p. 47). Because the Heller Cave springtail
co-occurs with the eastern small-footed bat, the potential negative
impacts of blasting activities at or around the Heller Cave complex
previously documented for the eastern small-footed bat may also have
potential negative impacts to the Heller Cave springtail, particularly
if the blasting activity causes damage to the structure of Heller Cave
5 such that the cave collapses or facilitates changes in
temperature, humidity, water quality, or water quantity. Therefore, we
conclude that information in the petition and readily available in our
files indicates that quarrying activities may be a threat to the Heller
Cave springtail and its habitat.
Summary of Factor A--In summary, information in the petition and
readily available in our files indicates that the present or threatened
destruction, modification, or curtailment of its habitat or range
through impacts associated with limestone quarry operations may be a
threat to the Heller Cave springtail.
B. Overutilization for Commercial, Recreational, Scientific, or
Educational Purposes
Information Provided in the Petition
The petitioner did not provide any information on overutilization
of the Heller Cave springtail.
Evaluation of Information Provided in the Petition and Available in
Service Files
We have no information in our files to suggest overutilization may
be a threat to the Heller Cave springtail.
Summary of Factor B--In summary, information in the petition and
readily available in our files does not indicate that overutilization
for commercial, recreational, scientific or educational purposes may be
a threat to the Heller Cave springtail. However, whether this factor is
a threat to the species will be further investigated during our 12-
month status review.
C. Disease or Predation
Information Provided in the Petition
The petitioner did not provide any information on disease or
predation of the Heller Cave springtail.
Evaluation of Information Provided in the Petition and Available in
Service Files
We have no information in our files to suggest disease or predation
may be a threat to the Heller Cave springtail.
Summary of Factor C--In summary, information in the petition and
readily available in our files does not indicate that disease or
predation may be a threat to the Heller Cave springtail. However,
whether this factor is a threat to the species will be further
investigated during our 12-month status review.
D. The Inadequacy of Existing Regulatory Mechanisms
Information Provided in the Petition
The petitioner makes three separate inadequacy of existing
regulatory mechanism assertions. First, the petitioner asserts that the
Heller Cave springtail has no protective status at the local, State, or
Federal level and, therefore, current regulatory mechanisms are
inadequate to protect it (Petition, p. 14). The petitioner further
states that even if the Heller Cave springtail was State-listed or a
species of concern, those protective statuses would likely provide
inadequate protection. This assertion is based on the petitioner's
assessment that the PADEP issued the small, non-coal mining permit
despite the documented presence of the eastern small-footed bat,

[[Page 67788]]

a State-designated threatened species, in Heller Cave (Petition, p.
15). Second, the petitioner asserts that recognition of the Heller
Caves complex as a ``Biological Diversity Area'' and ``Important Bird
Area'' is insufficient to regulate protection of the species (Petition,
p. 15). Third, the petitioner asserts that the State's current
environmental review and permitting process failed to protect the
Heller Cave springtail (Petition, p. 16).
Evaluation of Information Provided in the Petition and Available in
Service Files
The petitioner's first assertion is that the Heller Cave springtail
is not a protected species under current regulatory mechanisms at the
local, State, and Federal level, and therefore, those mechanisms are
inadequate to protect the species (Petition, p. 14). The petitioner
states that since there is a lack of regulatory recognition for the
species ``no deliberate program for its conservation can or has been
instituted'' (Petition, p. 15).
The petitioner's second assertion is that recognition of the Heller
Caves complex as a ``Biological Diversity Area'' and ``Important Bird
Area'' is insufficient to regulate protection of the Heller Cave
springtail (Petition, p. 15). A Biological Diversity Area (BDA) is
defined as ``An area containing plants or animals of special concern at
State or Federal levels, exemplary natural communities, or exceptional
native diversity. BDAs include both the immediate habitat and
surrounding lands important in the support of these special elements''
(WPC 2006, p. 6). The BDAs are used in conservation planning to
``identify core areas that delineate essential habitat that cannot
absorb significant levels of activity without substantial impact to the
elements of concern'' (WPC 2006, p. 6). An Important Bird Area (IBA) is
defined as ``a site that is part of a global network of places
recognized for their outstanding value to bird conservation'' with
application for conservation planning to maintain the areas for
valuable bird habitat (WPC 2006, p. 6). The Heller Caves complex site
is ranked as a BDA of high significance because it provides a ``winter
hibernation site for bat colonies, including the state and global-
concern species eastern small-footed myotis'' (WPC 2006, p. xi). The
BDA and IBA designations are nonregulatory community planning tools.
The petitioner concedes that ``designation as a BDA confers no
regulatory protection'' (Petition, p. 15).
Third, the petitioner asserts that the State's current
environmental review and permitting process failed to protect the
Heller Cave springtail or its habitat (Petition, p. 16). The proposed
Heller Cave limestone mine project overlaps the Heller Caves BDA. The
Heller Caves BDA contains the eastern small-footed bat and the Heller
Cave springtail (Petition, p. 16; WPA 2006, p. 46). The eastern small-
footed bat is a State-listed species and falls under the PGC's
jurisdiction. The Heller Cave springtail is neither a federally or
State-listed invertebrate nor a State species of concern (Shellenberger
2010, p. 1; Leppo 2010, p. 1). Information in our files at the time of
the petition's receipt indicates uncertainty as to whether the Heller
Cave springtail is a true aquatic invertebrate and, therefore, falls
under the PA Fish and Boat Commission's jurisdiction, or whether it is
a terrestrial invertebrate and therefore falls under PNHP's
jurisdiction (Leppo 2010, p. 1). The Service is unaware of which State
agencies the PADEP contacted to review the mine project for impacts to
the Heller Cave springtail.
The PGC was contacted to review the project for possible impacts to
the eastern small-footed bat (Petition, p. 11; Shellenberger 2010, p.
1). According to the Petition (p. 15), the PGC recommended a ``Total
Avoidance Area'' around Heller Cave because the proposed quarrying
project is likely to disturb or destroy winter and summer bat habitat.
The petitioner did not provide PGC's comments on the mining project to
the Service as part of the Petition's references, and those comments
are not readily available to the Service. We have no readily available
information to confirm the Petition's assertion that the existing
environmental review and mine permitting processes may be inadequate to
protect the Heller Cave springtail or its habitat, through the
surrogacy of the eastern small-footed bat. Based on review of the
Petition's information, we conclude that the Petition indicates that
the existing permit processes may be inadequate to protect the Heller
Cave springtail.
Summary of Factor D--In summary, information in the petition and
readily available in our files indicates that inadequate regulatory
mechanisms for (1) Factor A--the present or threatened destruction,
modification, or curtailment of the species' habitat caused by the
proposed limestone quarry or its mining operations; and (2) Factor E
(see below)--other natural or manmade factors affecting its continued
existence caused by mortality from the proposed limestone quarry's rock
removal and blasting operations may be a threat to the Heller Cave
springtail.
E. Other Natural or Manmade Factors Affecting Its Continued Existence
Information Provided in the Petition
The petitioner states that three anthropogenic factors are threats
to the Heller Cave springtail: (1) Direct mortality as a result of rock
removal and blasting, (2) cave vandalism and direct human-caused
mortality, and (3) climate change (Petition, pp. 16-17).
Evaluation of Information Provided in the Petition and Available in
Service Files
The petitioner first asserts, with no supporting information, that
the Heller Cave springtail is threatened from ``direct take'' (i.e.,
mortality) as a result of the proposed limestone quarry's rock removal
and blasting operations (Petition, p. 16). Information in our files
suggests that some of the proposed quarry activities may occur outside
of the Heller Cave core area (Stormer, 2010a, p. 1; Turner, 2010, p. 1;
Shellenberger 2010, p. 1). However, our information does not state how
much of the quarry operations or what type (i.e., blasting vs. land
clearing) of quarry operations may occur outside of the Heller Cave
core area. If blasting and rock removal activities take place within
the Heller Cave core area, including Heller Cave 5--the type
locality for the Heller Cave springtail and hibernacula site of the
eastern small-footed bat--those activities as described in the petition
may impact the Heller Cave springtail (Petition, pp. 10-14). Blasting
and rock removal activities may destabilize the cave site (WPC 2006,
pp. 46). If the cave destabilizes to the point that collapsing material
falls on the locations where the Heller Cave springtail specimens were
collected, then direct mortality may occur. We conclude that direct
mortality could occur from rock removal and blasting if those
activities occur within or very near the Heller Caves complex.
The petitioner further asserts that the Heller Cave springtail is
threatened by cave vandalism and intentional human-caused mortality.
The petitioner does not provide information to support this assertion,
merely stating that ``it is possible that one or more attempts could be
made to obliterate this unique species'' prior to protection under the
Act (Petition, p. 17). We do not have any information in our files to
indicate that this intentional harm may be a specific threat to the
Heller Cave springtail. We are not aware of specific vandalism
instances for eastern small-footed bat hibernacula in Pennsylvania or
for the Heller Caves complex. Therefore, it is unlikely that the cave
site itself may be

[[Page 67789]]

subjected to vandalism. However, we will fully investigate whether
intentional cave disturbance or vandalism is a threat to the Heller
Cave springtail and its habitat in our 12-month status review.
The petitioner lastly asserts that ``climate change may be
affecting the Heller Cave springtail at this time, or it may in the
future'' (Petition, p. 17). The petitioner cites three documents in
this section, only one of which can be assessed for accuracy. Of the
other two, the Natural Resource Council 2006 citation does not relate
to the information for which it is used as a citation. The Toomey and
Nolan 2005 citation is not included in the petitioner's list of
literature cited and consequently could not be quickly searched for or
located. The petitioner did not include copies of the references. The
petitioner's third citation is a Service (2011, p. 1) blog post about
climate change and its impacts on Indiana bat conservation efforts,
which includes a bat biologist quoted as saying ``Surface temperature
is directly related to cave temperature, so climate change will
inevitably affect the suitability of hibernacula'' (Petition, p. 17).
We have general information in our files indicating that climate
change is occurring. The Fourth Assessment Report: Climate Change 2007,
prepared by the Intergovernmental Panel on Climate Change (IPCC),
presents credible science on global climate change. The IPCC concludes
that warming of the climate system is unequivocal, as evidenced by
observations of increasing global average air and ocean temperatures,
widespread melting of snow and ice, and rising global average sea level
(IPCC 2007, p. 2). The warming trend is expected to continue as a
result of a projected increase of global greenhouse gas emissions by 25
to 90 percent from 2000 to 2030, which would be greater than the change
observed during the 20th century (IPCC 2007, p. 7). Although there is
some uncertainty regarding the mechanics of climate change and how much
temperatures will change, the projected global average surface increase
is estimated to range from 1.1 [deg]C to 6.4 [deg]C (2.0[emsp14][deg]F
and 11.5 [deg]F) in 2090 to 2099 over the temperatures observed during
the 19-year period of 1980 to 1999 (IPCC 2007, p. 8).
We do not have any readily available information as of the
petition's receipt that further refines the IPCC's (2007, entire)
conclusions at regional or local scales to allow us to assess whether,
or to what extent, the Heller Cave springtail may be impacted by
climate change. The petitioner acknowledges that how regional climate
change may impact the Heller Cave springtail is unknown (Petition, p.
17) but suggests the Heller Cave springtail ``would be highly
vulnerable to climate-related shifts in its physical environment''
because it is an ``extremely range-limited cave obligate'' species. As
discussed above in the Species Information section, information in our
files raises uncertainty as to whether the Heller Cave springtail may
occur only within Heller Cave, and by extension whether the species is
a cave obligate (Leppo 2010, p. 2). Because of the high levels of
uncertainty in regional or local scale climate change impacts and the
uncertainty of the Heller Cave springtail's cave endemism, we cannot
reasonably state that climate change may be a threat to the species.
However, we will fully investigate the potential effects of climate
change on the Heller Cave springtail in our 12-month status review.
Summary of Factor E--In summary, information in the petition and
readily available in our files indicates that direct take as a result
of the proposed limestone quarry's rock removal and blasting operations
may be a threat to the Heller Cave springtail, but does not indicate
that intentional take from cave disturbance and vandalism or from
climate change may be a threat to the species.

Finding

On the basis of our determination under section 4(b)(3)(A) of the
Act, we determine that the petition presents substantial scientific or
commercial information indicating that listing the Heller Cave
springtail throughout its entire range may be warranted. This finding
is based on information provided under factors A, D, and E. We
determine that the information provided under factors B and C is not
substantial.
Because we have found that the petition presents substantial
information indicating that listing the Heller Cave springtail may be
warranted, we are initiating a status review to determine whether
listing the Heller Cave springtail under the Act is warranted.
