SUPPLEMENTARY INFORMATION: Within 12 months after receiving any petition to revise the Federal Lists of Endangered and Threatened Wildlife and Plants, we are required to make a finding whether or not the petitioned action is warranted (‘‘12-month finding’’), unless we determined that the petition did not contain substantial scientific or commercial information indicating that the petitioned action may be warranted (section 4(b)(3)(B) of the Act (16 U.S.C. 1531 et seq.)). We must make a finding that the petitioned action is: (1) Not warranted; (2) warranted; or (3) warranted but precluded. ‘‘Warranted but precluded’’ means that (a) the petitioned action is warranted, but the immediate proposal 14:39 Dec 05, 2017 Docket No. Contact information Blackfin sucker ................................

However, we ask the public to submit to us at any time any new information that becomes available concerning the stressors to any of the species listed above or their habitats. DATES: The findings in this document were made on December 6, 2017. ADDRESSES: Detailed descriptions of the basis for each of these findings are available on the Internet at https:// www.regulations.gov under the following docket numbers: Jkt 244001 of a regulation implementing the petitioned action is precluded by other pending proposals to determine whether species are endangered or threatened species, and (b) expeditious progress is being made to add qualified species to the Federal Lists of Endangered and Threatened Wildlife and Plants (Lists) and to remove from the Lists species for which the protections of the Act are no longer necessary. Section 4(b)(3)(C) of the Act requires that we treat a petition for which the requested action is found to be warranted but precluded as though resubmitted on the date of such finding, that is, requiring that a subsequent finding be made within 12 months of that date. We must publish these 12month findings in the Federal Register. Summary of Information Pertaining to the Five Factors Section 4 of the Act (16 U.S.C. 1533) and the implementing regulations at PO 00000 Frm 00011 Fmt 4702 Sfmt 4702 part 424 of title 50 of the Code of Federal Regulations (50 CFR part 424) set forth procedures for adding species to, removing species from, or reclassifying species on the Federal Lists of Endangered and Threatened Wildlife and Plants. The Act defines ‘‘endangered species’’ as any species that is in danger of extinction throughout all or a significant portion of its range (16 U.S.C. 1532(6)), and ‘‘threatened species’’ as any species that is likely to become an endangered species within the foreseeable future throughout all or a significant portion of its range (16 U.S.C. 1532(20)). Under section 4(a)(1) of the Act, a species may be determined to be an endangered species or a threatened species because of any of the following five factors: (A) The present or threatened destruction, modification, or curtailment of its habitat or range; E:\FR\FM\06DEP1.SGM 06DEP1 jstallworth on DSKBBY8HB2PROD with PROPOSALS Federal Register / Vol. 82, No. 233 / Wednesday, December 6, 2017 / Proposed Rules (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 summarize below the information on which we based our evaluation of the five factors provided in section 4(a)(1) of the Act to determine whether the blackfin sucker, Mohave shoulderband snail, white-tailed prairie dog, and Woodville Karst cave crayfish meet the definition of ‘‘endangered species’’ or ‘‘threatened species.’’ The supporting information upon which the finding for each species is based is documented in a species assessment form that contains more-detailed biological information, a thorough analysis of the listing factors, and an explanation of why we determined that these species do not meet the definition of an endangered species or threatened species. These forms can be found at https:// www.regulations.gov under the appropriate docket number (see ADDRESSES, above). In considering what stressors under the Act’s five factors might indicate that the species may meet the definition of a threatened species or an endangered species, we must look beyond the mere exposure of the species to the stressor to determine whether the species responds to the stressor in a way that causes actual impacts to the species. If there is exposure to a stressor, but no response, or only a positive response, that stressor does not cause a species to meet the definition of a threatened species or an endangered species. If there is exposure and the species responds negatively, the stressor may be significant. In that case, we determine whether that stressor drives or contributes to the risk of extinction of the species such that the species warrants listing as an endangered or threatened species as those terms are defined by the Act. This does not necessarily require empirical proof of impacts to a species. The combination of exposure and some corroborating evidence of how the species is likely affected could suffice. The mere identification of stressors that could affect a species negatively is not sufficient to compel a finding that listing is appropriate; similarly, the mere identification of stressors that do not affect a listed species negatively is insufficient to compel a finding that delisting is appropriate. For a species to be listed or remain listed, we require evidence that these stressors are operative threats to the species and its habitat, either singly or in combination, VerDate Sep<11>2014 14:39 Dec 05, 2017 Jkt 244001 to the point that the species meets the definition of an endangered or a threatened species under the Act. In making these 12-month findings, we considered and thoroughly evaluated the best scientific and commercial information available regarding the past, present, and future stressors and threats. We reviewed the petitions, information available in our files, and other available published and unpublished information. These evaluations may include information from recognized experts; Federal, State, and tribal governments; academic institutions; foreign governments; private entities; and other members of the public. The species assessment forms for the blackfin sucker, Mohave shoulderband snail, white-tailed prairie dog, and Woodville Karst cave crayfish provide the basis for these findings and can be found on the Internet at https:// www.regulations.gov under the appropriate docket number (see ADDRESSES, above). The following are informational summaries for each of the findings in this document. Blackfin Sucker (Thoburnia atripinnis) Previous Federal Actions On April 20, 2010, we received a petition from the Center for Biological Diversity (Center), Alabama Rivers Alliance, Clinch Coalition, Dogwood Alliance, Gulf Restoration Network, Tennessee Forests Council, and West Virginia Highlands Conservancy requesting that the blackfin sucker be listed as an endangered or threatened species under the Act. On September 27, 2011, we published a 90-day finding in the Federal Register (76 FR 59836) concluding that the petition presented substantial information indicating that listing the blackfin sucker may be warranted. This document constitutes the 12-month finding on the April 20, 2010, petition to list the blackfin sucker. Summary of Finding The blackfin sucker is a fish that is relatively small (140 mm (5.5 in.) in length) in comparison to other members of its family, Catostomidae, collectively known as suckers. The species is endemic to the upper Barren River System in north-central Tennessee and south-central Kentucky, primarily upstream of Barren River Dam, with historical records known from only two stream systems downstream of the dam. Blackfin suckers inhabit clear headwater streams and are most frequently encountered in deeper sections of pools and runs. The species PO 00000 Frm 00012 Fmt 4702 Sfmt 4702 57563 is typically observed near bedrock ledges, slabrock boulders, rootwads, and undercut banks. During the March and April spawning period, males are associated with swift riffles and females occupy pools where they are found occasionally under flat rocks at the edges of riffles. We evaluated all relevant stressors under the five factors, including any regulatory mechanisms and conservation measures addressing these stressors. The primary stressors include effects of agriculture, sedimentation, stream modification, impoundments, and climate change. Despite impacts from these stressors, we find that the species has maintained the whole of its historical range and the number of occupied streams has increased. Considering that impacts from these stressors are expected to decrease or remain stable, and that the species exhibits redundancy, representation, and resiliency, we find that these stressors do not, alone or in combination, rise to a level that causes this species to meet the definition of a threatened species or an endangered species. Therefore, we find that listing the blackfin sucker as threatened or endangered is not warranted. A detailed discussion of the basis for this finding can be found in the blackfin sucker species assessment form and other supporting documents (see ADDRESSES, above). Mohave Shoulderband Snail (Helminthoglypta (Coyote) greggi) Previous Federal Actions On January 31, 2014, we received a petition from the Center requesting that the Mohave shoulderband snail be listed as an endangered or threatened species under the Act. We published a substantial 90-day finding in the Federal Register (80 FR 19259) on April 10, 2015. Subsequently, we entered into a stipulated settlement agreement with the Center that required us to submit a 12-month finding to the Federal Register by November 30, 2017. This document constitutes the 12-month finding on the January 31, 2014, petition to list the Mohave shoulderband snail. Summary of Finding The Mohave shoulderband snail is a small (0.48 to 0.58 in (12.3 to 14.6 mm) in length), brown desert snail. The species inhabits rock outcrops and talus slopes found on volcanic formations in the western region of the Mojave Desert at Middle Butte, Standard Hill, and Soledad Mountain. The species is dependent on local precipitation and subsequent increases E:\FR\FM\06DEP1.SGM 06DEP1 57564 Federal Register / Vol. 82, No. 233 / Wednesday, December 6, 2017 / Proposed Rules in humidity within rock outcrop habitats. Although water represents the primary limiting resource in desert environments, other climatic and physical factors—such as temperature, topography, and food availability, or a combination of these factors—can influence the ecology of desert snails. Because of the hot, arid conditions in the Mojave Desert, the snail is active primarily during the brief winter season and enters a state of dormancy below ground during the remainder of the year. It emerges during and following periods of rainfall in search of food resources or for mating and egg-laying activities. We evaluated all relevant stressors under the five factors, including any regulatory mechanisms and conservation measures addressing these stressors. The primary stressors include effects of habitat degradation from hard rock mining. We find that, while mining activities will likely result in some loss of suitable habitat, this loss will not lead to a significant decrease in the resources needed to meet the species’ physical and ecological needs across the species’ range. Furthermore, recent presence/ absence surveys have resulted in additional observations of the species throughout its range. In all, we find that mining and other potential stressors, alone or in combination, do not rise to a level that causes this species to meet the definition of a threatened species or an endangered species. Therefore, we find that listing the Mohave shoulderband snail as threatened or endangered is not warranted. A detailed discussion of the basis for this finding can be found in the Mohave shoulderband snail species assessment form and other supporting documents (see ADDRESSES, above). jstallworth on DSKBBY8HB2PROD with PROPOSALS White-Tailed Prairie Dog (Cynomys leucurus) Previous Federal Actions On July 15, 2002, we received a petition to list the white-tailed prairie dog as threatened or endangered. We published a not-substantial 90-day finding in the Federal Register (69 FR 64889) on November 9, 2004. On February 22, 2008, after we received notice of a lawsuit challenging the notsubstantial finding, we entered into a stipulated settlement agreement with the Center for Native Ecosystems and three other entities, to submit to the Federal Register a 12-month finding on the petition to list the white-tailed prairie dog. On June 1, 2010, we completed our status review and determined that the white-tailed prairie dog did not warrant listing (75 FR VerDate Sep<11>2014 14:39 Dec 05, 2017 Jkt 244001 30338). A September 9, 2014, court order remanded the 12-month notwarranted finding back to us for reconsideration (Rocky Mountain Wild v. U.S. Fish and Wildlife Service 2014, case 9:13–cv–00042–DWM). This finding constitutes our remanded 12month finding on the petition to list the white-tailed prairie dog, and addresses all issues raised in the court’s order. Summary of Finding The white-tailed prairie dog inhabits parts of Wyoming, Utah, Montana, and Colorado, and is one of five prairie dog species in western North America. The range of the white-tailed prairie dog has not changed appreciably since historical times, but historical poisoning campaigns, the introduction of plague, and habitat loss significantly reduced the abundance of white-tailed prairie dogs throughout its range. The white-tailed prairie dog generally inhabits drier landscapes with shrub land vegetation, such as the high desert scrub community of Utah and sagebrush steppe of western Wyoming. It prefers areas with lower vegetation heights to facilitate predator surveillance, but it also may use dense brush adjacent to grassier areas to avoid predators. The white-tailed prairie dog digs its burrows, which require deep, welldrained soils. We evaluated all relevant stressors under the five factors, including any regulatory mechanisms and conservation measures addressing these stressors. The primary stressors include effects of agricultural activities, shooting, poisoning, overgrazing, invasive weeds, wildfire, urbanization, energy development, drought, and plague. We found that white-tailed prairie dog populations are in moderate to high overall condition, with population trends stable or exhibiting some declines from stochastic events followed by recovery. In addition, white-tailed prairie dogs have multiple resilient populations, and exhibit adaptive capacity. Therefore, we find that these stressors do not, alone or in combination, rise to a level that causes this species to meet the definition of a threatened species or an endangered species. Therefore, we find that listing the white-tailed prairie dog as threatened or endangered is not warranted. A detailed discussion of the basis for this finding can be found in the white-tailed prairie dog species assessment form and other supporting documents (see ADDRESSES, above). PO 00000 Frm 00013 Fmt 4702 Sfmt 4702 Woodville Karst Cave Crayfish (Procambarus orcinus) Previous Federal Actions On April 20, 2010, we received a petition from the Center requesting that the Woodville Karst cave crayfish be listed as an endangered or threatened species under the Act. On September 27, 2011, we published a 90-day finding in the Federal Register (76 FR 59836) concluding that the petition presented substantial information indicating that listing the Woodville Karst cave crayfish may be warranted. This document constitutes the 12-month finding on the April 20, 2010, petition to list the Woodville Karst cave crayfish. Summary of Finding The Woodville Karst cave crayfish is a subterranean species of crayfish endemic to several freshwater springs and sink caves within the panhandle of Florida. The adults are approximately 25 mm (1 in) in length and have a semitransparent cuticle revealing pinkish orange tissue underneath. The species is known from 18 aquatic cave sites, all of which are within an area of approximately 100 square miles. It lives in shallow water at the mouth of sink holes to depths of 91 m (300 ft) and appears to require a flowing, freshwater, subterranean environment. However, specific water-quality requirements for the species are unknown. We evaluated all relevant stressors under the five factors, including any regulatory mechanisms and conservation measures addressing these stressors. The primary stressors include effects of land-use activities and direct alterations of waterways, water withdrawal, sea-level rise, and overutilization. These stressors do not, alone or in combination, rise to a level that causes this species to meet the definition of a threatened species or an endangered species. Additionally, despite the potential for groundwater decline over time, populations are likely to remain resilient and be minimally affected since the species lives at significant spring depths and can move among springs and sinks in the underground system. Therefore, we find that listing the Woodville Karst cave crayfish as threatened or endangered is not warranted. A detailed discussion of the basis for this finding can be found in the Woodville Karst cave crayfish species assessment form and other supporting documents (see ADDRESSES, above).

SUPPLEMENTARY INFORMATION: Background On September 20, 2017, NMFS received a petition from Blue Water Fishermen’s Association to identify the Northwest Atlantic leatherback turtle as a DPS and list it as threatened under the ESA. The species is currently listed as endangered throughout its range under the ESA (35 FR 8491, June 2, 1970). Copies of the petitions are available upon request (see ADDRESSES). ESA Statutory, Regulatory, and Policy Provisions and Evaluation Framework Section 4(b)(3)(A) of the ESA of 1973, as amended (16 U.S.C. 1531 et seq.), requires, to the maximum extent practicable, that within 90 days of receipt of a petition to list a species as threatened or endangered, the Secretary of Commerce make a finding on whether that petition presents substantial scientific or commercial information indicating that the petitioned action may be warranted, and to promptly publish such finding in the Federal Register (16 U.S.C. 1533(b)(3)(A)). When it is found that substantial scientific or commercial information in a petition indicates the petitioned action may be warranted (a ‘‘positive 90-day finding’’), we are required to promptly commence a review of the status of the species concerned during which we will conduct a comprehensive review of the best available scientific and commercial information. In such cases, we conclude the review with a finding as to whether, in fact, the petitioned action is warranted within 12 months of receipt of the petition. Because the finding at the 12-month stage is based on a more thorough review of the available information, as compared to the narrow scope of review at the 90-day stage, a ‘‘may be warranted’’ finding does not prejudge the outcome of the status review. Under the ESA, a listing determination may address a species, which is defined to also include subspecies and, for any vertebrate species, any DPS that interbreeds when mature (16 U.S.C. 1532(16)). A joint NMFS-U.S. Fish and Wildlife Service (USFWS) policy clarifies the agencies’ interpretation of the phrase ‘‘distinct population segment’’ for the purposes of listing, delisting, and reclassifying a species under the ESA (i.e., ‘‘DPS Policy;’’ 61 FR 4722, February 7, 1996). A species, subspecies, or DPS is ‘‘endangered’’ if it is in danger of extinction throughout all or a significant portion of its range, and ‘‘threatened’’ if E:\FR\FM\06DEP1.SGM 06DEP1

SUPPLEMENTARY INFORMATION:

Background

    Within 12 months after receiving any petition to revise the Federal 
Lists of Endangered and Threatened Wildlife and Plants, we are required 
to make a finding whether or not the petitioned action is warranted 
(``12-month finding''), unless we determined that the petition did not 
contain substantial scientific or commercial information indicating 
that the petitioned action may be warranted (section 4(b)(3)(B) of the 
Act (16 U.S.C. 1531 et seq.)). We must make a finding that the 
petitioned action is: (1) Not warranted; (2) warranted; or (3) 
warranted but precluded. ``Warranted but precluded'' means that (a) the 
petitioned action is warranted, but the immediate proposal of a 
regulation implementing the petitioned action is precluded by other 
pending proposals to determine whether species are endangered or 
threatened species, and (b) expeditious progress is being made to add 
qualified species to the Federal Lists of Endangered and Threatened 
Wildlife and Plants (Lists) and to remove from the Lists species for 
which the protections of the Act are no longer necessary. Section 
4(b)(3)(C) of the Act requires that we treat a petition for which the 
requested action is found to be warranted but precluded as though 
resubmitted on the date of such finding, that is, requiring that a 
subsequent finding be made within 12 months of that date. We must 
publish these 12-month findings in the Federal Register.

Summary of Information Pertaining to the Five Factors

    Section 4 of the Act (16 U.S.C. 1533) and the implementing 
regulations at part 424 of title 50 of the Code of Federal Regulations 
(50 CFR part 424) set forth procedures for adding species to, removing 
species from, or reclassifying species on the Federal Lists of 
Endangered and Threatened Wildlife and Plants. The Act defines 
``endangered species'' as any species that is in danger of extinction 
throughout all or a significant portion of its range (16 U.S.C. 
1532(6)), and ``threatened species'' as any species that is likely to 
become an endangered species within the foreseeable future throughout 
all or a significant portion of its range (16 U.S.C. 1532(20)). Under 
section 4(a)(1) of the Act, a species may be determined to be an 
endangered species or a threatened species because of any of the 
following five factors:
    (A) The present or threatened destruction, modification, or 
curtailment of its habitat or range;

[[Page 57563]]

    (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 summarize below the information on which we based our evaluation 
of the five factors provided in section 4(a)(1) of the Act to determine 
whether the blackfin sucker, Mohave shoulderband snail, white-tailed 
prairie dog, and Woodville Karst cave crayfish meet the definition of 
``endangered species'' or ``threatened species.'' The supporting 
information upon which the finding for each species is based is 
documented in a species assessment form that contains more-detailed 
biological information, a thorough analysis of the listing factors, and 
an explanation of why we determined that these species do not meet the 
definition of an endangered species or threatened species. These forms 
can be found at https://www.regulations.gov under the appropriate docket 
number (see ADDRESSES, above).
    In considering what stressors under the Act's five factors might 
indicate that the species may meet the definition of a threatened 
species or an endangered species, we must look beyond the mere exposure 
of the species to the stressor to determine whether the species 
responds to the stressor in a way that causes actual impacts to the 
species. If there is exposure to a stressor, but no response, or only a 
positive response, that stressor does not cause a species to meet the 
definition of a threatened species or an endangered species. If there 
is exposure and the species responds negatively, the stressor may be 
significant. In that case, we determine whether that stressor drives or 
contributes to the risk of extinction of the species such that the 
species warrants listing as an endangered or threatened species as 
those terms are defined by the Act. This does not necessarily require 
empirical proof of impacts to a species. The combination of exposure 
and some corroborating evidence of how the species is likely affected 
could suffice. The mere identification of stressors that could affect a 
species negatively is not sufficient to compel a finding that listing 
is appropriate; similarly, the mere identification of stressors that do 
not affect a listed species negatively is insufficient to compel a 
finding that delisting is appropriate. For a species to be listed or 
remain listed, we require evidence that these stressors are operative 
threats to the species and its habitat, either singly or in 
combination, to the point that the species meets the definition of an 
endangered or a threatened species under the Act.
    In making these 12-month findings, we considered and thoroughly 
evaluated the best scientific and commercial information available 
regarding the past, present, and future stressors and threats. We 
reviewed the petitions, information available in our files, and other 
available published and unpublished information. These evaluations may 
include information from recognized experts; Federal, State, and tribal 
governments; academic institutions; foreign governments; private 
entities; and other members of the public.
    The species assessment forms for the blackfin sucker, Mohave 
shoulderband snail, white-tailed prairie dog, and Woodville Karst cave 
crayfish provide the basis for these findings and can be found on the 
Internet at https://www.regulations.gov under the appropriate docket 
number (see ADDRESSES, above). The following are informational 
summaries for each of the findings in this document.

Blackfin Sucker (Thoburnia atripinnis)

Previous Federal Actions

    On April 20, 2010, we received a petition from the Center for 
Biological Diversity (Center), Alabama Rivers Alliance, Clinch 
Coalition, Dogwood Alliance, Gulf Restoration Network, Tennessee 
Forests Council, and West Virginia Highlands Conservancy requesting 
that the blackfin sucker be listed as an endangered or threatened 
species under the Act. On September 27, 2011, we published a 90-day 
finding in the Federal Register (76 FR 59836) concluding that the 
petition presented substantial information indicating that listing the 
blackfin sucker may be warranted. This document constitutes the 12-
month finding on the April 20, 2010, petition to list the blackfin 
sucker.

Summary of Finding

    The blackfin sucker is a fish that is relatively small (140 mm (5.5 
in.) in length) in comparison to other members of its family, 
Catostomidae, collectively known as suckers. The species is endemic to 
the upper Barren River System in north-central Tennessee and south-
central Kentucky, primarily upstream of Barren River Dam, with 
historical records known from only two stream systems downstream of the 
dam.
    Blackfin suckers inhabit clear headwater streams and are most 
frequently encountered in deeper sections of pools and runs. The 
species is typically observed near bedrock ledges, slabrock boulders, 
rootwads, and undercut banks. During the March and April spawning 
period, males are associated with swift riffles and females occupy 
pools where they are found occasionally under flat rocks at the edges 
of riffles.
    We evaluated all relevant stressors under the five factors, 
including any regulatory mechanisms and conservation measures 
addressing these stressors. The primary stressors include effects of 
agriculture, sedimentation, stream modification, impoundments, and 
climate change. Despite impacts from these stressors, we find that the 
species has maintained the whole of its historical range and the number 
of occupied streams has increased. Considering that impacts from these 
stressors are expected to decrease or remain stable, and that the 
species exhibits redundancy, representation, and resiliency, we find 
that these stressors do not, alone or in combination, rise to a level 
that causes this species to meet the definition of a threatened species 
or an endangered species. Therefore, we find that listing the blackfin 
sucker as threatened or endangered is not warranted. A detailed 
discussion of the basis for this finding can be found in the blackfin 
sucker species assessment form and other supporting documents (see 
ADDRESSES, above).

Mohave Shoulderband Snail (Helminthoglypta (Coyote) greggi)

Previous Federal Actions

    On January 31, 2014, we received a petition from the Center 
requesting that the Mohave shoulderband snail be listed as an 
endangered or threatened species under the Act. We published a 
substantial 90-day finding in the Federal Register (80 FR 19259) on 
April 10, 2015. Subsequently, we entered into a stipulated settlement 
agreement with the Center that required us to submit a 12-month finding 
to the Federal Register by November 30, 2017. This document constitutes 
the 12-month finding on the January 31, 2014, petition to list the 
Mohave shoulderband snail.

Summary of Finding

    The Mohave shoulderband snail is a small (0.48 to 0.58 in (12.3 to 
14.6 mm) in length), brown desert snail. The species inhabits rock 
outcrops and talus slopes found on volcanic formations in the western 
region of the Mojave Desert at Middle Butte, Standard Hill, and Soledad 
Mountain.
    The species is dependent on local precipitation and subsequent 
increases

[[Page 57564]]

in humidity within rock outcrop habitats. Although water represents the 
primary limiting resource in desert environments, other climatic and 
physical factors--such as temperature, topography, and food 
availability, or a combination of these factors--can influence the 
ecology of desert snails. Because of the hot, arid conditions in the 
Mojave Desert, the snail is active primarily during the brief winter 
season and enters a state of dormancy below ground during the remainder 
of the year. It emerges during and following periods of rainfall in 
search of food resources or for mating and egg-laying activities.
    We evaluated all relevant stressors under the five factors, 
including any regulatory mechanisms and conservation measures 
addressing these stressors. The primary stressors include effects of 
habitat degradation from hard rock mining. We find that, while mining 
activities will likely result in some loss of suitable habitat, this 
loss will not lead to a significant decrease in the resources needed to 
meet the species' physical and ecological needs across the species' 
range. Furthermore, recent presence/absence surveys have resulted in 
additional observations of the species throughout its range. In all, we 
find that mining and other potential stressors, alone or in 
combination, do not rise to a level that causes this species to meet 
the definition of a threatened species or an endangered species. 
Therefore, we find that listing the Mohave shoulderband snail as 
threatened or endangered is not warranted. A detailed discussion of the 
basis for this finding can be found in the Mohave shoulderband snail 
species assessment form and other supporting documents (see ADDRESSES, 
above).

White-Tailed Prairie Dog (Cynomys leucurus)

Previous Federal Actions

    On July 15, 2002, we received a petition to list the white-tailed 
prairie dog as threatened or endangered. We published a not-substantial 
90-day finding in the Federal Register (69 FR 64889) on November 9, 
2004. On February 22, 2008, after we received notice of a lawsuit 
challenging the not-substantial finding, we entered into a stipulated 
settlement agreement with the Center for Native Ecosystems and three 
other entities, to submit to the Federal Register a 12-month finding on 
the petition to list the white-tailed prairie dog. On June 1, 2010, we 
completed our status review and determined that the white-tailed 
prairie dog did not warrant listing (75 FR 30338). A September 9, 2014, 
court order remanded the 12-month not-warranted finding back to us for 
reconsideration (Rocky Mountain Wild v. U.S. Fish and Wildlife Service 
2014, case 9:13-cv-00042-DWM). This finding constitutes our remanded 
12-month finding on the petition to list the white-tailed prairie dog, 
and addresses all issues raised in the court's order.

Summary of Finding

    The white-tailed prairie dog inhabits parts of Wyoming, Utah, 
Montana, and Colorado, and is one of five prairie dog species in 
western North America. The range of the white-tailed prairie dog has 
not changed appreciably since historical times, but historical 
poisoning campaigns, the introduction of plague, and habitat loss 
significantly reduced the abundance of white-tailed prairie dogs 
throughout its range.
    The white-tailed prairie dog generally inhabits drier landscapes 
with shrub land vegetation, such as the high desert scrub community of 
Utah and sagebrush steppe of western Wyoming. It prefers areas with 
lower vegetation heights to facilitate predator surveillance, but it 
also may use dense brush adjacent to grassier areas to avoid predators. 
The white-tailed prairie dog digs its burrows, which require deep, 
well-drained soils.
    We evaluated all relevant stressors under the five factors, 
including any regulatory mechanisms and conservation measures 
addressing these stressors. The primary stressors include effects of 
agricultural activities, shooting, poisoning, overgrazing, invasive 
weeds, wildfire, urbanization, energy development, drought, and plague. 
We found that white-tailed prairie dog populations are in moderate to 
high overall condition, with population trends stable or exhibiting 
some declines from stochastic events followed by recovery. In addition, 
white-tailed prairie dogs have multiple resilient populations, and 
exhibit adaptive capacity. Therefore, we find that these stressors do 
not, alone or in combination, rise to a level that causes this species 
to meet the definition of a threatened species or an endangered 
species. Therefore, we find that listing the white-tailed prairie dog 
as threatened or endangered is not warranted. A detailed discussion of 
the basis for this finding can be found in the white-tailed prairie dog 
species assessment form and other supporting documents (see ADDRESSES, 
above).

Woodville Karst Cave Crayfish (Procambarus orcinus)

Previous Federal Actions

    On April 20, 2010, we received a petition from the Center 
requesting that the Woodville Karst cave crayfish be listed as an 
endangered or threatened species under the Act. On September 27, 2011, 
we published a 90-day finding in the Federal Register (76 FR 59836) 
concluding that the petition presented substantial information 
indicating that listing the Woodville Karst cave crayfish may be 
warranted. This document constitutes the 12-month finding on the April 
20, 2010, petition to list the Woodville Karst cave crayfish.

Summary of Finding

    The Woodville Karst cave crayfish is a subterranean species of 
crayfish endemic to several freshwater springs and sink caves within 
the panhandle of Florida. The adults are approximately 25 mm (1 in) in 
length and have a semitransparent cuticle revealing pinkish orange 
tissue underneath.
    The species is known from 18 aquatic cave sites, all of which are 
within an area of approximately 100 square miles. It lives in shallow 
water at the mouth of sink holes to depths of 91 m (300 ft) and appears 
to require a flowing, freshwater, subterranean environment. However, 
specific water-quality requirements for the species are unknown.
    We evaluated all relevant stressors under the five factors, 
including any regulatory mechanisms and conservation measures 
addressing these stressors. The primary stressors include effects of 
land-use activities and direct alterations of waterways, water 
withdrawal, sea-level rise, and overutilization. These stressors do 
not, alone or in combination, rise to a level that causes this species 
to meet the definition of a threatened species or an endangered 
species. Additionally, despite the potential for groundwater decline 
over time, populations are likely to remain resilient and be minimally 
affected since the species lives at significant spring depths and can 
move among springs and sinks in the underground system. Therefore, we 
find that listing the Woodville Karst cave crayfish as threatened or 
endangered is not warranted. A detailed discussion of the basis for 
this finding can be found in the Woodville Karst cave crayfish species 
assessment form and other supporting documents (see ADDRESSES, above).
