Endangered Species Law & Policy

As we have previously reported, on December 6, the Biden Administration released the Fall 2023 Unified Agenda of Regulatory and Deregulatory Actions (Unified Agenda), which lists the regulatory and deregulatory actions that federal administrative agencies—including the U.S. Fish and Wildlife Service (Service)—plan to take in the coming year. According to the Unified Agenda, the western United States can expect a number of proposed and final rules to list species as threatened or endangered under the Endangered Species Act (ESA) and to designate critical habitat ...

On February 23, the U.S. Fish and Wildlife Service (Service) issued a proposed rule to list two distinct population segments (DPSs) of the California spotted owl (Strix occidentalis) as endangered and threatened species under the Endangered Species Act (ESA). The two DPSs are the Coastal-Southern California DPS, which the Service proposes to list as endangered, and the Sierra Nevada DPS, which the Service proposes to list as threatened with a rule issued under section 4(d) of the ESA (4(d) rule). The proposed rule also serves as the Service’s 12-month finding on a petition to list ...

On October 25, 2022, the Center for Biological Diversity (CBD) sued the U.S. Fish and Wildlife Service (Service) over the agency’s failure to timely finalize a proposed rule to list the lesser prairie-chicken (Tympanuchus pallidicinctus) (LEPC). CBD seeks an order from the court declaring the Service is in violation of the Endangered Species Act (ESA) by failing to timely list the LEPC and requiring the Service to publish one or more final rules by a date certain.

On June 1, 2021, and in response to a 2016 petition to list the LEPC, the Service proposed to list two distinct population ...

On February 8, 2022, the U.S. Fish and Wildlife Service (Service) published findings on several petitions to list species under the Endangered Species Act (ESA), some of which have been highly anticipated.

Pursuant to an August 2020 settlement agreement between the Service, WildEarth Guardians, and Western Watersheds Project, the Service published a 12-month finding on a petition to list the Sonoran desert tortoise (Gopherus morafkai). The tortoise is patchily distributed across 68,600 square miles in the Sonoran Desert ecoregion of Arizona and Sonora, Mexico. In its 12-month ...

On October 25, the U.S. Fish and Wildlife Service (Service) published a proposed rule to designate critical habitat for the coastal distinct population segment (DPS) of Pacific marten (Martes caurina), also known as coastal marten, under the federal Endangered Species Act (ESA).  In the proposed rule, the Service identifies a total of approximately 1,413,305 acres of land in northwestern California and southwestern Oregon to designate as critical habitat for the coastal marten. 

Listed as a threatened species in October 2020, the coastal marten is a medium-sized carnivore in the ...

On Monday, June 18, 2018, the U.S. Fish and Wildlife Service (FWS) announced that it has initiated five year status reviews for fifty species in California, Nevada, and the Klamath Basin of Oregon, pursuant to the Endangered Species Act (ESA).  Included among the species whose ESA listing status is being reviewed are 19 animal species, four of which are currently listed as threatened, while the remaining 14 are currently listed as endangered.  Additionally, the FWS is reviewing thirty-one plant species.

As part of its review, FWS will be accepting new information pertinent to the ...

On February 6, 2018, the National Marine Fisheries Service (NMFS) announced an extension of the public comment period for the 5-year review of the endangered Western Distinct Population Segment (DPS) of the Steller sea Lion (Eumetopias jubatus).  The Western DPS includes Steller sea lions that reside in the central and western Gulf of Alaska, Aleutian Islands, as well as those that inhabit coastal waters in Asia.  According to the Federal Register notice, the extension of the comment period to April 6, 2018 was issued in response to a request for additional time.  In addition ...

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 ...

Earlier this month, the U.S. Fish & Wildlife Service (Service) announced (pdf) the availability of its recovery plan (pdf) for the threatened southwest Alaska Distinct Population Segment of the northern sea otter (Enhydra lutris kenyoni).  The recovery plan describes the status of the otter, its history, and a number of actions the Service believes will allow for the delisting of the otter.  With respect to the otter's declining status, the recovery plan states that "[t]he only identified threat factor that is judged to have a high importance to recovery is predation[,]" and ...
