We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to delist the wood bison ( Bison bison athabascae ) under the Endangered Species Act of 1973, as amended (Act). Based on our review, we find that the petition does not present substantial information indicating that delisting the wood bison subspecies may be warranted. Therefore, we are not initiating a status review in response to this petition. However, we ask the public to submit to us any new information that becomes available concerning the status of, or threats to, the wood bison or its habitat at any time.

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to list the Oregon Cascades-California population and Black Hills population of the black-backed woodpecker ( Picoides arcticus ) under the Endangered Species Act of 1973, as amended (Act), as subspecies or distinct population segments (DPSs) that are endangered or threatened, and to designate critical habitat concurrent with listing. Based on our review, we find that the petition presents substantial scientific or commercial information indicating that listing the Oregon Cascades-California and Black Hills populations of the black-backed woodpecker as subspecies or DPSs may be warranted. Therefore, with the publication of this notice, we are notifying the public that, when funds become available, we will be initiating a review of the status of the two populations to determine if listing either or both the Oregon Cascades-California population and the Black Hills population as either subspecies or DPSs is warranted. To ensure that this status review is comprehensive, we are requesting scientific and commercial data and other information regarding these two populations. 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.

We, the U.S. Fish and Wildlife Service (Service), announce the reopening of the comment period on our October 11, 2012 (77 FR 61938), proposal to list Taylor's checkerspot butterfly as endangered and streaked horned lark as threatened and to designate critical habitat, and on our December 11, 2012 (77 FR 73770), proposal to list four subspecies of Mazama pocket gopher (Olympia, Tenino, Yelm, and Roy Prairie) and to designate critical habitat, under the Endangered Species Act of 1973, as amended (Act). We also announce the availability of a draft economic analysis (DEA) of the proposed critical habitat designations and an amended required determinations section of the proposed designations. The draft economic analysis addresses the potential economic impacts of critical habitat designation for all six subspecies (collectively, the “prairie species”) under consideration in these rulemakings. In addition, we are providing information that we inadvertently omitted from the preamble to the October 11, 2012, proposed rule (77 FR 61938) to list Taylor's checkerspot butterfly as endangered and streaked horned lark as threatened and to designate critical habitat. We are reopening the comment periods to allow all interested parties an opportunity to comment simultaneously on the proposed rules, the associated DEA, and our amended required determinations. Comments previously submitted on these proposed rulemakings do not need to be resubmitted, as they will be fully considered in preparation of the final rules. We also announce a public hearing and three public information workshops on our proposed rules and associated documents.

We are reopening the comment period to allow all interested parties an opportunity to comment simultaneously on the proposed rule, the associated DEA, and the amended required determinations section. Comments previously submitted on this rulemaking do not need to be resubmitted, as they will be fully considered in preparation of the final rule. We also announce a public hearing and public information meeting on our proposed rule and associated documents.

We, the U.S. Fish and Wildlife Service (Service), in cooperation with the State of Alaska, propose to establish a nonessential experimental population of wood bison in central Alaska, in accordance with section 10(j) of the Endangered Species Act of 1973, as amended. This proposal, if made final, would also establish provisions under which wood bison in Alaska would be managed. We are seeking comments on this proposal and on our draft environmental assessment, prepared pursuant to the National Environmental Policy Act of 1969, as amended, which analyzes the potential environmental impacts associated with the proposed reintroduction.

We, the U.S. Fish and Wildlife Service (Service), propose to list the blue-throated macaw ( Ara glaucogularis ) as endangered under the Endangered Species Act of 1973, as amended (Act). This species is endemic to a small area in Bolivia, and there are estimated to be fewer than 150 individuals remaining in the wild. Its population continues to decrease despite intense conservation efforts. The primary threat to the species is lack of reproductive success (loss of nestlings) due to nest failure, which primarily is caused by competition for nest sites and predation by larger avian species, in addition to diminished availability of suitable habitat. We seek information from the public on the proposed listing for this species.

We, the U.S. Fish and Wildlife Service (Service), propose to list as endangered the Honduran emerald hummingbird ( Amazilia luciae ) under the Endangered Species Act of 1973, as amended (Act). This species is endemic to a small area in Honduras, and the population is estimated to be less than 1,000 and decreasing. Its suitable habitat has decreased in the past 100 years and continues to diminish. This document also serves as the completion of the status review (also known as the 12-month finding). We seek information from the public on the proposed listing for this species.

We, the U.S. Fish and Wildlife Service (Service or USFWS), propose to reclassify the continental United States (U.S.) breeding population of wood stork from endangered to threatened under the Endangered Species Act of 1973, as amended (Act). We find that the best available scientific and commercial data indicate that the endangered designation no longer correctly reflects the current status of the continental U.S. breeding population of the wood stork due to a substantial improvement in the species' overall status. This proposed rule also constitutes our 12-month finding on the petition to reclassify the species.

We, the U.S. Fish and Wildlife Service (Service), announce a 90-day finding on a petition to list the African lion ( Panthera leo leo ) as endangered under the Endangered Species Act of 1973, as amended (Act). Based on our review, we find that the petition presents substantial scientific or commercial information indicating that listing this subspecies may be warranted. Therefore, with the publication of this notice, we are initiating a review of the status of the subspecies to determine if listing the African lion is warranted. To ensure that this status review is comprehensive, we are requesting scientific and commercial data and other information regarding this subspecies. 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.

We, the U.S. Fish and Wildlife Service (Service), under the authority of the Endangered Species Act of 1973, as amended (Act), announce the initiation of a status review of the Preble's meadow jumping mouse ( Zapus hudsonius preblei ) (Preble's) throughout its range. We conduct status reviews to determine whether a species should be listed as endangered or threatened under the Act. Following this status review, we will issue a 12-month finding on two petitions to delist Preble's. Because a status review also is required for the 5-year review of listed species under section 4(c)(2)(A) of the Act, we are electing to prepare these reviews simultaneously. At the conclusion of these simultaneous reviews, we will issue the 12-month finding on the petitions, as provided in section 4(b)(3)(B) of the Act, and make the requisite determination under section 4(c)(2)(B) of the Act based on the results of the 5-year review. Through this notice, we encourage all interested parties to provide us information regarding the Preble's. We also announce the availability of new information relevant to our consideration of the status of the Preble's.

In this Candidate Notice of Review (CNOR), we, the U.S. Fish and Wildlife Service (Service), present an updated list of plant and animal species native to the United States that we regard as candidates for or have proposed for addition to the Lists of Endangered and Threatened Wildlife and Plants under the Endangered Species Act of 1973, as amended. Identification of candidate species can assist environmental planning efforts by providing advance notice of potential listings, allowing landowners and resource managers to alleviate threats and thereby possibly remove the need to list species as endangered or threatened. Even if we subsequently list a candidate species, the early notice provided here could result in more options for species management and recovery by prompting candidate conservation measures to alleviate threats to the species. The CNOR summarizes the status and threats that we evaluated in order to determine that species qualify as candidates and to assign a listing priority number (LPN) to each species or to determine that species should be removed from candidate status. Additional material that we relied on is available in the Species Assessment and Listing Priority Assignment Forms (species assessment forms) for each candidate species. Overall, this CNOR recognizes two new candidates, changes the LPN for nine candidates, and removes three species from candidate status. Combined with other decisions for individual species that were published separately from this CNOR in the past year, the current number of species that are candidates for listing is 192. This document also includes our findings on resubmitted petitions and describes our progress in revising the Lists of Endangered and Threatened Wildlife and Plants (Lists) during the period October 1, 2011, through September 30, 2012. We request additional status information that may be available for the 192 candidate species identified in this CNOR.

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.

We, the U.S. Fish and Wildlife Service (Service), announce the availability of our final Supplemental Environmental Impact Statement on the Translocation of Southern Sea Otters (final SEIS). The final SEIS evaluates options for continuing, revising, or terminating the southern sea otter translocation program, which was initiated in 1987. The purpose of the program was to achieve a primary recovery action for the southern sea otter: to create an established population at San Nicolas Island sufficient to repopulate other areas of the range should a catastrophic event affect the mainland population. The document describes the proposed action and alternatives under consideration and discloses the direct, indirect, and cumulative environmental effects of each of the alternatives.

We, the U.S. Fish and Wildlife Service (Service), propose to revise designation of critical habitat for the Comal Springs dryopid beetle ( Stygoparnus comalensis ), Comal Springs riffle beetle ( Heterelmis comalensis ), and Peck's cave amphipod ( Stygobromus pecki ), under the Endangered Species Act of 1973, as amended (Act). In total, approximately 169 acres (68 hectares) are being proposed for revised critical habitat. The proposed revision of critical habitat is located in Comal and Hays Counties, Texas.

We, the U.S. Fish and Wildlife Service (Service), propose to list 15 species on the Hawaiian island of Hawaii as endangered species under the Endangered Species Act of 1973, as amended (Act), and to designate critical habitat for 1 of these species. For the remaining 14 species that we are proposing to list in this rule, we find that critical habitat is not determinable at this time. We also propose to designate critical habitat for two plant species that were listed as endangered species in 1986 and 1994. The proposed critical habitat designation totals 18,766 acres (ac) (7,597 hectares (ha)), and includes both occupied and unoccupied habitat. Approximately 55 percent of the area being proposed as critical habitat is already designated as critical habitat for 42 plants and the Blackburn's sphinx moth ( Manduca blackburni ). In addition, we propose a taxonomic change for one endangered plant species.

We, the U.S. Fish and Wildlife Service, determine endangered species status for the Alabama pearlshell ( Margaritifera marrianae ), round ebonyshell ( Fusconaia rotulata ), southern kidneyshell ( Ptychobranchus jonesi ), and Choctaw bean ( Villosa choctawensis ), and threatened species status for the tapered pigtoe ( Fusconaia burkei ), narrow pigtoe ( Fusconaia escambia ), southern sandshell ( Hamiota australis ), and fuzzy pigtoe ( Pleurobema strodeanum ), under the Endangered Species Act of 1973, as amended (Act); and designate critical habitat for the eight mussel species. The effect of this regulation is to conserve these eight mussel species and their habitat under the Act.

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on two petitions to list the Mexican gray wolf ( Canis lupus baileyi ) (Mexican wolf) as an endangered subspecies or Distinct Population Segment (DPS) and designate critical habitat under the Endangered Species Act of 1973, as amended (Act). Although not listed as a subspecies or DPS, the Mexican wolf is currently listed as endangered within the broader 1978 gray wolf listing, as revised, which listed the gray wolf in the lower 48 States and Mexico. Therefore, because all individuals that comprise the petitioned entity already receive the protections of the Act, we find that the petitioned action is not warranted at this time. However, we continue to review the appropriate conservation status of all gray wolves that comprise the 1978 gray wolf listing, as revised, and we may revise the current listing based on the outcome of that review.

We, the U.S. Fish and Wildlife Service (Service), announce a 12-month finding on a petition to list as an endangered or threatened species Erigeron lemmonii (Lemmon fleabane). After a review of the best available scientific information we find that listing the Lemmon fleabane as an endangered or threatened species is no longer warranted, and therefore we are removing this species from the candidate list. We propose to list Echinomastus erectocentrus var. acunensis (acuña cactus) and Pediocactus peeblesianus var. fickeiseniae (Fickeisen plains cactus) as an endangered species, and we propose to designate critical habitat for both cactus species under the Endangered Species Act of 1973, as amended (Act). If finalized, the effect of these regulations would be to add acuña cactus and Fickeisen plains cactus to the List of Endangered and Threatened Plants and to designate critical habitat for these species.
