Endangered Species Law & Policy

At its February 2018 meeting, the California Fish and Game Commission (Commission) received the one-year status review report on a petition to list tricolored blackbird (Agelaius tricolor) as a threatened or endangered species from the Department of Fish and Wildlife (Department).  In the status report the Department recommends listing the species as threatened under the California Endangered Species Act.  Because the species is so widely distributed and abundant, listing could have major impacts on building, farming, and public infrastructure activities and projects across ...

On January 30, 2018, the National Marine Fisheries Service (NMFS) issued a final rule listing the oceanic whitetip shark (Carcharinus lonigmanus) as a threatened species under the Endangered Species Act (ESA).  This final listing rule is the culmination of NMFS’ analysis following the 2015 petition filed by Defenders of Wildlife seeking to either list the species range-wide or, alternatively, to list two distinct populations (DPSs) of the oceanic whitetip shark.  In the final rule, NMFS notes that the shark is a globally-distributed species that has not undergone any range ...

As 2018 approaches, the U.S. Fish and Wildlife Service (Service) made a few announcements that will likely impact the list of threatened and endangered species.  In these last 11 days of 2017, the Service announced 90-day findings on petitions to list or reclassify five species, and 12-month findings on petitions to list or de-list two species under the ESA.

• On December 20, 2017, the Service announced 90-day findings on petitions for five separate species. The Service found that the petitioned actions for each of the five species may be warranted, based on the information presented in ...

In the Fall 2017 publication of the Unified Agenda of the Office of Information and Regulatory Affairs, the Department of the Interior announced its intent to revise the U.S. Fish and Wildlife Service’s regulations governing interagency cooperation and exceptions to the conservation of endangered and threatened species of fish, wildlife, and plants. In a separate announcement in the same publication, the Department of the Interior stated that it intends to revise regulations governing the listing of endangered and threatened species and the designation of critical ...

Long ago, the framers of the Constitution decided to separate the federal government's powers into three branches, with each branch acting as a check on the other.  Broadly speaking, the legislative branch writes the law, the judicial branch decides what the law means, and the executive branch decides how to enforce the law.  Sometimes, however, the powers can overlap among the branches.

For example, besides writing the laws, the legislative branch also approves the budgets for the various federal agencies.  And if a particular agency budget does not include funds for ...

On October 17, 2017, the California Fish and Game Commission (Commission) published notice of its preliminary positive finding on a petition to list the Cascades frog (Rana cascadae) as threatened or endangered under the California Endangered Species Act (CESA).  The Cascades frog inhabits a variety of habitats—including large lakes, ponds, wet meadows and streams—at mid-to-high elevations from the Klamath-Trinity region, along the Cascades Range axis in the vicinity of Mt. Shasta, southward to the headwater tributaries of the Feather River.  The California populations ...

On Thursday, October 5, 2017, the U.S. Fish & Wildlife Service (Service) announced 12-month not warranted findings on petitions to list 25 species as endangered or threatened under the Endangered Species Act (ESA).  It is likely that the Service’s not warranted findings represent the Trump administration’s departure from the previous administration’s  90-day determinations wherein the Service found that the petitions contain substantial information that listing may be warranted.  For over half of the 25 species, the not warranted findings satisfy the terms of various ...

On September 20, 2017, the U.S. Fish and Wildlife Service (USFWS) listed three separate species under the Endangered Species Act ("ESA").  USFWS listed the Sonoyta mud turtle (Kinosternon sonoriense) as endangered, and the 'I'iwi (Drepanis coccinea) and pearl darter (Percina aurora) as threatened species under the ESA.  Despite listing all three species, the USFWS deferred designating critical habitat for the three species.  The three listing decisions, all of which were compelled by settlements that the USFWS entered into during the Obama administration, are summarized below.

On January 11, 2017, the U.S. Fish and Wildlife Service (Service) published a final rule listing the rusty patched bumble bee (Bombus affinis) as endangered under the Endangered Species Act (ESA).  The rusty patched bumble bee’s historic range encompassed areas of 28 states and the District of Columbia (Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Pennsylvania, Rhode Island, South Carolina, South Dakota ...

The Candidate Notice of Review is an annual appraisal by the U.S. Fish and Wildlife Service (Service) of plants and animals that are candidates for Endangered Species Act protection.  A "candidate" species is a species for which there is sufficient information to support a proposal for listing as an endangered or threatened species under the Endangered Species Act, but the formal listing determination is delayed because of higher priority listing actions for other species.  The Candidate Notice of Review, among other things, "summarizes the status and threats ...

On October 5, 2016, the U.S. Fish and Wildlife Service (Service) listed a beetle species as endangered, a fish species as threatened, and designated critical habitat for the fish species pursuant to the Endangered Species Act (ESA).

The Service listed the Miami tiger beetle (Cicindelidia floridana), which occurs in Miami-Dade County, Florida, as endangered under the ESA.  According to the Service, the decline in the species is due to the impact of habitat loss, degradation, and fragmentation, the inadequacy of existing regulatory protections, and the beetle’s relatively ...

On August 25, 2016, the California Fish and Game Commission (Commission) voted unanimously to list the northern spotted owl (Strix occidentalis caurina) as a threatened species under the California Endangered Species Act.  The owl is already listed as a threatened species under the Federal Endangered Species Act.  The Commission's action increased protections for the species by allowing for state and citizen enforcement actions through the California Department of Fish and Wildlife and the state courts.

In California, the northern spotted owl’s range extends south along ...

On August 10, 2016, the U.S. Fish and Wildlife Service (USFWS) issued a proposed rule to list the Texas hornshell (Popenaias popeii), a freshwater mussel, as an endangered species under the Endangered Species Act (ESA).  The species has been on the candidate species list for over a decade, and the proposed rule meets a listing determination deadline established by a 2011 multidistrict settlement agreement.  In the proposed rule, USFWS determined that the species is in danger of extinction due to habitat loss from loss of water flow, decreased water quality, increased accumulation of ...

On June 2, 2016, the U.S. Fish and Wildlife Service (Service) issued a 90-day finding that listing populations of the Northwestern moose (Alces alces andersoni) under the Endangered Species Act (ESA) may be warranted.  The Service’s 90-day finding is in response to a petition filed in July 2015 by the Center for Biological Diversity and Honor the Earth, which asked that the moose be listed as a threatened or endangered distinct population segment (DPS).

The U.S. population of Northwestern moose inhabits the upper peninsula of Michigan, Minnesota, North Dakota and Wisconsin.  In ...

After filing an appeal with the U.S. Court of Appeals for the Fifth Circuit less than two weeks prior, on May 10, 2016, the U.S. Fish and Wildlife Service (Service) filed an unopposed motion to voluntarily dismiss its appeal of the district court decision that vacated the listing of the lesser prairie-chicken (Tympanuchus pallidicinctus) as threatened under the Endangered Species Act (ESA).  The U.S. District Court for the Western District of Texas, Midland Division, identified a number of errors in the Service’s evaluation of the species under the criteria laid out in the ...

On April 21, 2016, the U.S. Fish and Wildlife Service and National Marine Fisheries Service (collectively, Service) announced revisions to their proposed modifications  to  the Endangered Species Act (ESA) petition process. 81 Fed. Reg. 23,448 (Apr. 21, 2016) (pdf).  In May 2015, the Service announced proposed changes to the petition process for listing a species or seeking to change the listing status of a species under the ESA. 80 Fed. Reg. 29,286 (May 21, 2015) (pdf).  The Service’s proposed rule originally required petitions to list species to address only one species, contain ...

On April 4, 2016, the U.S. District Court for the District of Montana vacated the U.S. Fish and Wildlife Service’s (Service) August 13, 2014 withdrawal of its proposed rule to list the distinct population segment of the North American wolverine (Withdrawal).  The Withdrawal signaled a complete departure from the Service’s February 2013 proposed rule to list the wolverine as a threatened species under the Endangered Species Act (ESA).  The court’s decision is the newest chapter in what has been a contentious and storied path to a listing decision for the North American ...

On March 15, 2016, in Alaska Oil & Gas Association v. National Marine Fisheries Service, case number 4:14-cv-00029-RRB, the U.S. District Court for the District of Alaska vacated a final regulation promulgated by the National Marine Fisheries Service ("NMFS") listing the Arctic subspecies of ringed seal (Phoca hispida hispida, Phoca hispida ochotensis, and Phoca hispida botanica) as threatened and the Ladoga subspecies of ringed seal (Phoca hispida ladogensis) as endangered under the Endangered Species Act ("ESA").  The State of Alaska, North Slope Borough and the Alaska Oil ...

On February 29, 2016, the U.S. District Court for the Western District of Texas rejected the U.S. Fish and Wildlife Service's (Service) request to reinstate federal Endangered Species Act (ESA) protections for the lesser prairie chicken (Tympanuchus pallidicinctus).  Permian Basin Petrol. Ass 'n v. Dep 't of the Interior, No. 7:14-CV-50 (W.D. Tex. Feb. 29, 2016.).  In September 2015, the court ruled on a challenge brought by the Permian Basin Petroleum Association and four New Mexico counties and vacated the final rule listing the lesser prairie chicken as threatened under the ESA.  ...

In a notice published on January 15, 2016, the U.S. Fish and Wildlife Service (Service) announced a draft methodology for prioritizing species status reviews and 12-month findings on petitions for listing species under the Endangered Species Act (ESA).  81 Fed. Reg. 2,229 (Jan. 15, 2016).  The Service currently has over 500 unresolved species status reviews and associated 12-month findings on petitions for listing, and intends to use the changes to its methods to set priorities on how and when those unresolved petitions will be addressed.  The Service’s draft methodology will not ...

On December 24, 2015, the U.S. Fish and Wildlife Service (Service) released its annual Candidate Notice of Review (CNOR) summarizing the status of species that qualify as candidates for listing under the Endangered Species Act (ESA).  The 2015 CNOR identifies all species designated as candidates and explains the changes to the candidate list from the 2014 CNOR.  The Service assigns each candidate species a listing priority number (LPN) indicating the magnitude of the threat to a species’ continued existence (with one being the highest priority, and twelve being the lowest ...

On December 10, 2015, the California Fish and Game Commission (Commission) voted to advance the tricolored blackbird (Agelaius tricolor) as a candidate species for listing under the California Endangered Species Act (CESA).  The species is now subject to the same legal protections as endangered or threatened species under CESA.

As we previously reported, on June 11, 2015, the Commission voted not to make the tricolored blackbird a candidate for listing under CESA.  The species had been listed on an emergency basis in December 2014 but, as a result of the Commission’s inaction in ...

On October 27, 2015, the U.S. Fish and Wildlife Service (Service) issued a memorandum to the Service Regional Directors announcing new guidance to streamline findings on petitions to list species under the Endangered Species Act (ESA).  The stated purpose of the guidance is to streamline petition findings while ensuring [the Service] conducts an adequate review of petitions.   The memorandum clarifies that this guidance is interim guidance until the Service’s amendments to its petition listing rules are final.  Once finalized, the guidance will supersede previous guidance ...

During the last week of its fiscal year, the U.S. Fish and Wildlife Service (Service) made several findings under section 4 of the Endangered Species Act (ESA) to meet its obligations under the 2011 listing settlement workplan.  Below is a brief summary of these findings.

On September 29, 2015, the Service published a proposed rule to list four plant species from South Florida (specifically Miami-Dade and Monroe counties).  These include the Big Pine partridge pea (Chamaecrista lineata var. keyensis), the wedge spurge (Chamaesyce deltoidea ssp. Serpyllum) the sand flax (Linum ...

On September 22, 2015, Secretary of the Interior Sally Jewell announced that the greater sage-grouse (Centrocercus urophasianus) does not warrant protection under the Endangered Species Act (ESA).  The Department of the Interior is calling the greater sage-grouse strategy the largest land conservation effort in U.S. history and a 21^st-century approach to conservation.  In reaching its not warranted finding, the U.S. Fish and Wildlife Service (Service) relied upon the collective conservation efforts of the Bureau of Land Management (BLM), U.S. Forest Service (USFS), State ...

On August 6, 2015, the California Fish and Game Commission (Commission) voted to list the southern Sierra Nevada evolutionarily significant unit of the fisher (Pekania pennati) as a threatened species under the California Endangered Species Act, but determined not to list the northern California evolutionarily significant unit.  In doing so, the Commission followed the recommendation of the California Department of Fish and Wildlife (Department).

According to the Department’s status review, [n]ative populations of fishers currently occur in Canada, the western United ...

On July 1, 2015, the U.S. Fish and Wildlife Service (Service) published notice of its 90-day findings on petitions to list 31 species under the Endangered Species Act (ESA).  Of these 31 species, all of which occur in the United States, the Service made positive 90-day findings on 21 petitions.  A positive finding on a listing petition prompts a 12-month review of each species by the Service to determine whether listing is warranted.  Of the remaining ten petitions, the Service concluded that nine petitions failed to provide substantial information demonstrating that listing action may be warranted.  Most species addressed in the findings originated from a 53-species mega-petition filed by the Center for Biological Diversity (CBD) in July 2012.  If the Service finalizes its May 21, 2015 proposed rule to revise the regulations for species listing petitions, multi-species petitions such as the one filed by CBD will no longer be accepted by the Service.

Perhaps most notably, the Service’s publication included a denial of the petition to reclassify or downlist the gray wolf (Canis lupis) from its current status as endangered to threatened.  Twenty-two petitioners (including the Humane Society of the United States, CBD, and the Sault Sainte Marie Tribe of Chippewa Indians) signed the 2015 petition requesting reclassification of the gray wolf (excluding the Mexican wolf subspecies (Canis lupus baileyi) throughout the conterminous United States).  The Service first concluded that the petition failed to provide substantial information indicating that the population proposed for reclassification may qualify as a distinct population segment.  The Service acknowledged that this finding alone was enough to deny the petition for reclassification, but stated that the status of the gray wolf has been a source of significant controversy over the past few years, and due to the controversy, also concluded that the petition did not provide substantial information indicating that the gray wolf at large would qualify as threatened rather than endangered.

Today, in response to a petition to list (pdf) filed by the Center for Biological Diversity (CBD) in October 2014, the California Fish and Game Commission (Commission) determined not to make the tricolored blackbird (agelaius tricolor) a candidate for listing under the California Endangered Species Act (CESA).  As we reported, the Commission previously — in December 2014 — decided to list the species on an emergency basis principally on the basis of the petition and without the benefit of input from the California Department of Fish and Wildlife and interested parties.  The ...

On May 29, 2015, the U.S. Bureau of Land Management (BLM),  in cooperation with the U.S. Forest Service, released Final Environmental Impact Statements for proposed amendments to existing Resource Management Plans (RMPs) for lands in ten western states.  The RMP amendments would establish conservation measures for the greater sage grouse (Centrocercus urophasianus) for approximately 50 million acres of federally-managed lands in California, Colorado, Idaho, Montana, Nevada, North Dakota, Oregon, South Dakota, Utah and Wyoming. The proposed RMP amendments are intended to ...

On April 27, 2015, the Chairman of the House Armed Services Committee, released the text (pdf) of the National Defense Authorization Act (Act), including language that would ban the U.S. Fish and Wildlife Service (Service) from issuing its listing decision for the greater sage-grouse (Centrocercus urophasianus) under the Endangered Species Act (ESA) through September 30, 2025.  The Act would also limit the application of federal conservation plans for the species.

As we previously reported, the greater sage-grouse is a candidate species under the ESA.  In 2010, the Service ...

After a relatively quiet start to the year, the National Marine Fisheries Service (NMFS) and U.S. Fish & Wildlife Service (FWS)  have issued findings and rules regarding the proposed listings of four separate species under the Endangered Species Act (ESA) over the last two days.  NMFS issued a 90-day finding on a petition to list the Gulf of Mexico population of Bryde's whale (Balaenoptera edeni) on April 6, 2015.  FWS issued a 12-month finding on a petition to list the Humboldt marten (Martes caurina humboldtensis) and proposed to list two species of crayfish - the Big Sandy crayfish ...

On February 10, 2015, the National Marine Fisheries Service and the National Oceanic Atmospheric Administration ("Services") issued a final rule (pdf) to include captive killer whales in the Southern Resident killer whale distinct population segment (DPS) of killer whales (Orcinus orca). The DPS has been listed as endangered under the federal Endangered Species Act (ESA) since 2005, but the listing excluded whales held in captivity. In January 2013, People for the Ethical Treatment of Animals petitioned the Services to remove the exclusion and extend the protections of ...

Today, in response to a petition to list (pdf) filed by the Center for Biological Diversity (CBD) in October 2014, the California Fish and Game Commission (Commission) extended protection to the tricolored blackbird (agelaius tricolor) on an emergency basis under the California Endangered Species Act.  The Commission previously -- in 2005 -- denied a petition from CBD to list the species.

While the tricolored blackbird is endemic to California, it is distributed through much of the State.  Census data on the species has been collected periodically over the past 20 years.  The ...

On November 12, 2014, the U.S. Fish & Wildlife Service (Service) listed as threatened and designated over 1.4 million acres of critical habitat for Gunnison sage-grouse (Centrocercus minimus), the smaller cousin of the greater sage-grouse (Centrocercus urophasianus).  The Gunnison sage-grouse’s (Gunnison) current range is limited to southwestern Colorado and southeastern Utah.

The regulations came as a blow to the State of Colorado, landowners, and others who have devoted considerable resources to the conservation of the Gunnison Basin population’s sagebrush ...

On October 6, the U.S. Fish and Wildlife Service (Service) issued a news release (pdf) announcing its proposal to list the West Coast Distinct Population Segment (West Coast DPS) of fisher (Pekanian pennanti) as threatened under the Federal Endangered Species Act (ESA), in part due to significant threats from illegal marijuana farming. 

The fisher belongs to a family of mammals that includes weasels and otters, and grows to about the size of a large house cat.  The Federal Register notice (pdf) regarding the proposed listing, which was published yesterday, states that the ...

The U.S. Fish and Wildlife Service (Service) has published (pdf) a proposed rule to list 21 species as endangered and 2 species as threatened under the Endangered Species Act (ESA). Of the 21 species the Service proposes to list as endangered, twelve are plant species and nine are animal species. The two proposed threatened species are animal species.

All 23 species are found in the U.S. Territory of Guam and the U.S. Commonwealth of the Northern Mariana Islands. According to the proposed rule, the species are experiencing population level impacts as a result of habitat loss and ...

Last Friday, the U.S. Fish and Wildlife Service (Service) published its final rule listing the western yellow-billed cuckoo (Coccyzus americanus) as threatened under the Endangered Species Act (ESA). The species is an insect-eating bird found in riparian woodland habitat. The final rule lists loss of riparian habitat as the primary threat to the species and notes that conversion to agriculture, dam construction, river flow management, and overgrazing have all contributed to loss of the species’ habitat over the last several decades. The species has been listed in twelve ...

On September 30, 2014, the U.S. District Court for the District of Columbia upheld (PDF) the U.S. Fish and Wildlife Service’s (Service) decision to withdraw (PDF) its proposal to list the dunes sagebrush lizard as an endangered species.  The Service found that threats to the lizard and its habitat have been reduced such that the species no longer meets the statutory definition of an endangered (or threatened) species.  

The dunes sagebrush lizard’s (Sceloporus arenicolus) range spans approximately 745,000 acres across southeastern New Mexico and western Texas in shinnery oak ...

The U.S. Fish and Wildlife Service (Service) has declined to list two Nevada plants under the Endangered Species Act (ESA). On Wednesday, the Service published its 12-month findings on a petition to list the Churchill Narrows buckwheat (Eriogonum diatomaceum) and the Las Vegas buckwheat (Eriogonum corymbosum var. nilesii).

Section 4(a)(1) of the ESA lists five factors that the Service must examine when deciding whether to list a species as threatened or endangered: (1) the present or threatened destruction, modification, or curtailment of its habitat or range; (2 ...

On September 12, 2014, the U.S. Fish and Wildlife Service (Service) published notice of its final rule listing the Georgia rockcress (Arabis georgiana) as a threatened plant species under the Endangered Species Act.  On the same day, the Service published notice of its final rule designating 732 acres within Georgia and Alabama as critical habitat for the species.  Designated critical habitat for the Georgia rockcress includes riparian and river bluff habitat within Gordon, Floyd, Harris, Muscogee and Clay Counties in Georgia and Bibb, Dallas, Elmore, Monroe, Sumter, and ...

 On Friday, the U.S. Fish and Wildlife Service (Service) issued a final rule (pdf) revising the critical habitat designation for the contiguous United States distinct population segment (DPS) of the Canada lynx (Lynx canadensis) and revising the boundary of the Canada lynx DPS. The revised critical habitat designation consists of approximately 38,954 square miles of critical habitat in five units in Idaho, Maine, Minnesota, Montana, Washington, and Wyoming.

The Service’s final rule also rescinds the existing State-boundary-based definition of the Canada lynx DPS and ...

Last Thursday, the U.S. Fish and Wildlife Service (Service) issued a final rule listing two plants as endangered under the Endangered Species Act (ESA). The two species, Florida brickell-bush (Brickellia mosieri) and Carter’s small-flowered flax (Linum carteri carteri), are both native to Miami-Dade County, Florida. According to the Service, the species’ habitat has suffered degradation as a result of inadequate fire management, nonnative plant species, and human activities. The brickell-bush is known to be present in just 17 sites, while Carter’s small-flowered ...

In a 90-day finding (pdf) published this morning in the Federal Register, the National Marine Fisheries Service (NMFS) found that the listing of the orange clownfish (Amphiprion percula) "may be warranted" under the Endangered Species Act.  This finding was based in large part on the threat from "bleaching and subsequent loss of anemone habitat resulting from ocean warming" to three species of anemone that host the orange clownfish.  NMFS is now conducting a full status review of the species, and it has solicited scientific and commercial information pertaining to the ...

On August 20, 2014, the U.S. Fish and Wildlife Service (Service) declined to list (pdf) the Upper Missouri River Distinct Population Segment of the Arctic Grayling (Thymallus arcticus) as threatened or endangered under the Endangered Species Act.

According to the Service, ongoing conservation efforts initiated by private landowners and federal and state officials have worked to improve conditions for the species. These voluntary programs, including irrigation flow reductions and fish ladders, have improved habitat quality for the trout. The Service estimates that these ...

 The U.S. Fish and Wildlife Service (Service) announced today that it is withdrawing its proposal to list the North American wolverine (Gulo gulo luscus) as threatened under the Endangered Species Act (ESA). The decision to withdraw the listing proposal followed the consensus recommendation of the Service’s three Regional Directors for the regions encompassing the wolverine’s known range in the contiguous United States – the Mountain Prairie, Pacific Northwest, and Pacific Southwest regions.

As we previously reported, the Regional Director of the Service’s Mountain ...

On August 4, 2014, the U.S. Fish and Wildlife Service (Service) announced its decision to list two small Texas minnows -- the sharpnose shiner (Notropis oxyrhynchus) and smalleye shiner (N. buccula) -- as endangered under the Endangered Species Act (ESA).  The two Texas minnows, which have been candidates species since 2002, measure less than 2 inches and have a life span of less than three years.  According to the announcement issued by the Service, the "two primary  factors affecting the status of the shiners are river fragmentation and alterations of the natural stream flow regime ...

Today, the U.S. Fish and Wildlife Service (Service) issued a final rule (pdf) protecting three flowers under the Endangered Species Act (ESA). The three flowers -- the Short's bladderpod (Physaria globosa), fleshy-fruit gladecress (Leavenworthia crassa), and whorled sunflower (Helianthus verticillatus) -- are found in Alabama, Georgia, Indiana, Kentucky, and Tennessee.

According to the Service, whorled sunflowers are primarily threatened by industrial forestry and pine plantations. The flowers grow to be six feet tall and live in moist, prairie-like areas, woodlands ...

A Regional Director for the U.S. Fish and Wildlife Service (Service) has directed federal biologists to withdraw their proposed rule to list the wolverine (Gulo gulo luscus) as threatened under the Endangered Species Act. As we reported here, the Service proposed listing the wolverine in February 2013, citing habitat loss due to climate change as the primary threat to the species. Officials in Wyoming, Idaho, and Montana objected to the proposed listing, arguing climate change conclusions are premature. In response to these objections, the Service asked a panel of nine biologists ...

Today, the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service issued their final interpretation of the phrase "significant portion of its range" for the purposes of applying the Endangered Species Act (ESA).  This phrase plays a key role in the listing and delisting of species, as it appears in the ESA's definition of "endangered species" and "threatened species."  Specifically, under the ESA, an "endangered species" is defined as "any species which is in danger of extinction throughout all or a significant portion of its ...

The U.S. Fish and Wildlife Service (Service) issued a final rule (pdf) listing the New Mexico meadow jumping mouse (Zapus hudsonius luteus) as endangered under the Endangered Species Act.

The jumping mouse is a small mammal that hibernates eight or nine months out of the year, which is longer than most mammals. In the three or four months it is active, the jumping mouse must breed, birth, raise its young, and store up sufficient fat reserves to survive the next hibernation period. In addition, the jumping mouse has a limited lifespan of three years or less, and produces only one small ...
