Endangered Species Law & Policy

On October 3, 2023, the U.S. Fish and Wildlife Service (Service) published two proposed rules to list three species—the northwestern pond turtle (Actinemys marmorata), the southwestern pond turtle (Actinemys pallida), and the short-tailed snake (Lampropeltis extenuata)—as threatened under the Endangered Species Act (ESA). The proposed listings also include proposed 4(d) rules for each species. However, according to the Federal Register notices, the Service concluded that designating critical habitat for each of the three species is not currently determinable, and ...

On Tuesday, September 26, President Biden vetoed two Republican-sponsored joint resolutions, S.J. Res. 9 and S.J. Res. 24, seeking to undo Endangered Species Act (ESA) protections for the lesser prairie-chicken (LEPC) (Tympanuchus pallidicinctus) and northern long-eared bat (NLEB) (Myotis septentrionalis) that became effective in January 2023.

S.J. Res. 9 would have undone the U.S. Fish and Wildlife Service’s (Service) final rule listing the Northern distinct population segment (DPS) of the LEPC as threatened with a section 4(d) rule and the Southern DPS as endangered ...

On August 29, 2023, the U.S. Fish and Wildlife Service (Service) published a final rule listing two distinct population segments (DPS)—the North Feather and Central Coast DPSs—of the foothill yellow-legged frog (Rana boylii) (Frog) as threatened (Threatened DPSs) and two additional DPSs of the Frog—the South Sierra and South Coast DPSs—as endangered (Endangered DPSs) under the Endangered Species Act (ESA). In the preamble to the final rule, the Service indicated that designating critical habitat for all four DPSs of the Frog is not determinable at this time due to a lack ...

On August 11, 2023, the U.S. Fish and Wildlife Service (Service) published a proposed rule to delist the Apache trout (Oncorhynchus apache) under the Endangered Species Act (ESA) due to the species’ recovery.  The Apache trout, the state fish of Arizona, is a species of freshwater fish that is found primarily in the mountain region of southeast Arizona.  This species was initially listed as an endangered species under the ESA in 1967.  Then, in 1975, the Service downlisted the species to threatened status.  The ESA defines a threatened species as one that is “likely to become ...

On July 25, 2023, the U.S. Fish and Wildlife Service (Service) published a proposed rule to list two mussel species, the Salina mucket (Potamilus metnecktayi) and Mexican fawnsfoot (Truncilla cognata), as endangered under the Endangered Species Act (ESA). The Service also proposed to designate critical habitat for these species under the ESA. The proposed critical habitat for the Salina mucket would amount to approximately 200 river miles in the Texan counties of Brewester, Terrell, and Val Verde, and the proposed critical habitat for the Mexican fawnsfoot would amount to ...

On July 20, 2023, the U.S. Fish and Wildlife Service (Service) issued a final rule listing the cactus ferruginous pygmy-owl (Glaucidium brasilianum cactorum) (“Owl”) as a threatened subspecies with a 4(d) rule under the Endangered Species Act (ESA). The 4(d) rule prohibits the same activities prohibited for endangered species, but allows exemptions for certain education and outreach activities permitted under a Migratory Bird Treaty Act permit, surveying and monitoring in Arizona under a state scientific activity permit, and habitat restoration and enhancement ...

On June 22, 2023, the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS) (collectively, the Services), issued three sets of proposed revisions to their Endangered Species Act (ESA) regulations addressing: (1) interagency consultations under ESA section 7; (2) the procedures and criteria for listing, reclassifying, delisting, and designating critical habitat for species under ESA section 4; and (3) reinstatement of USFWS’s blanket ESA section 4(d) rule which, prior to its repeal in 2019, extended the take prohibitions of ESA section 9 to all ...

On May 15, 2023, the U.S. Fish and Wildlife Service (Service) issued two mitigation policies: one titled “Mitigation Policy” and another titled “Endangered Species Act Compensatory Mitigation Policy.” The Mitigation Policy provides a framework to inform Service mitigation procedure and policy, while the Endangered Species Act (ESA) Compensatory Mitigation Policy provides guidance on implementation of the ESA through compensatory mitigation mechanisms. The Service states that both policies are intended as guidelines for Service personnel to follow when ...

On May 17, 2023, the U.S. Court of Appeals for the Ninth Circuit (Ninth Circuit) issued its decision in Center for Biological Diversity v. U.S. Fish and Wildlife Service (Case No. 20-15654), a case in which a mining company challenged the U.S. Fish and Wildlife Service’s (Service) designation of certain areas in southern Arizona as critical habitat for the jaguar (Panthera onca) under the Endangered Species Act (ESA). The Ninth Circuit upheld the district court’s ruling that the Service improperly designated the challenged area as occupied critical habitat. With respect to the ...

The critical habitat designation consists of almost entirely public land, with the exception of approximately 63 acres of privately owned land (however ...

On April 3, the U.S. Fish and Wildlife Service (Service) rejected a petition filed by a group of environmental organizations under section 4(e) of the Endangered Species Act (ESA) to list the coyote (Canis latrans) as an endangered species due to its similarity of appearance to the endangered Mexican wolf (C. lupus baileyi). Section 4(e) of the ESA gives the Service the ability to list a species on the basis that its “similarity of appearance” to an endangered or threatened species imperils the protected species’ survival and recovery.

In the petition, the environmental ...

Last week, the U.S. District Court for the District of Columbia issued a ruling allowing the Center for Biological Diversity (CBD) to continue pursuing its large Endangered Species Act (ESA) lawsuit against the U.S. Fish and Wildlife Service (Service) and the Department of the Interior.

The underlying lawsuit, filed in 2019, alleges that the Service violated the ESA by failing to timely publish 12-month findings on nearly 200 listing petitions, final listing determinations for six species, and designations of critical habitat for four species.  In response, the Service filed a ...

On March 9, the U.S. Fish and Wildlife Service (Service) issued its 12-month finding that listing Joshua trees (Yucca brevifolia and Y. jaegeriana) as endangered or threatened species under the Endangered Species Act (ESA) is not warranted. The 12-month finding was made to comply with a September 20, 2021 court-ordered remand of the Service’s previous “not warranted” finding in August 2019.

In September 2015, WildEarth Guardians submitted a petition to list the Joshua trees as threatened and, if applicable, designate critical habitat for the species. The Service issued ...

On February 28, 2023, I published a post on the Center for California Water Resources Policy and Management’s DeltaCurrents blog discussing Species Status Assessments (SSAs) as a tool to facilitate implementation of the federal Endangered Species Act (ESA). The U.S. Fish and Wildlife Service (Service) describes the SSA framework as “an analytical approach developed . . . to deliver foundational science for informing all [ESA] decisions.” The Service has explained it intends SSAs to provide “focused, repeatable, and rigorous scientific assessment” that results in ...

On February 6, the U.S. District Court for the Northern District of California sided with the Bureau of Reclamation (Reclamation) and plaintiffs Institute for Fisheries Resources, Pacific Coast Federation of Fishermen’s Associations, and the Yurok Tribe, in holding that an order governing Reclamation’s operation of Upper Klamath Lake (UKL) from the Oregon Water Resources Department (OWRD) is preempted by the Endangered Species Act (ESA). The order, issued in the midst of a recent drought to meet the needs of irrigators, mandated Reclamation to “immediately preclude or ...

On February 9, 2023, the U.S. Fish and Wildlife Service (Service) published proposed revisions to its regulations governing incidental take and enhancement of survival permitting under Endangered Species Act (ESA) section 10.

If finalized, the regulations would do away with the distinction between candidate conservation agreements with assurances and safe harbor agreements, clarify that incidental take permits no longer need to have a federally listed species as the “lead” species, codify aspects of the agency’s five-point policy that provide detail on the necessary ...

This January, the Department of the Interior and the Department of Commerce announced updated civil monetary penalties for violations of federal wildlife and natural resource protection laws including the Endangered Species Act (ESA), Marine Mammal Protection Act (MMPA), Bald and Golden Eagle Protection Act (BGEPA), Magnuson-Stevens Fishery Conservation and Management Act (Magnuson-Stevens), Lacey Act, National Marine Sanctuaries Act (NMSA), and others.

The Federal Civil Penalties Inflation Adjustment Act Improvements Act of 2015 requires federal agencies to adjust ...

Earlier this month, the U.S. Court of Appeals for the Ninth Circuit issued a ruling holding that the United States Fish and Wildlife Service’s (Service) decision not to modify a recovery plan for the grizzly bear (ursus arctos horrbilis) was not a final agency action subject to review under the Administrative Procedure Act (APA).

In 1975, the Service listed the grizzly bear as a threatened species under the Endangered Species Act (ESA).  At the time of listing, the grizzly bear’s population in the contiguous United States fell to between 700-800 individuals.  Pursuant to its ...

On January 24, 2023, the U.S. Fish and Wildlife Service (Service) proposed to designate approximately 104 river miles as critical habitat for the sickle darter (Percina williamsi) under the Endangered Species Act (ESA). The critical habitat designation would be divided into six areas—Little River, Emory River and Rock Creek, Copper Creek, North Fork Holston River, Middle Fork Holston River, and Sequatchie River—which together span Bledsoe, Blount, Morgan, and Roane Counties in Tennessee, and Scott, Smyth, and Washington Counties in Virginia. Nearly 80 percent of the ...

On November 30, 2022, the U.S. Fish and Wildlife Service (Service) issued a final rule listing the northern long-eared bat (NLEB) (Myotis septentrionalis) as an endangered species under Section 4 of the Endangered Species Act (ESA), reclassifying it from its former threatened status and rescinding its section 4(d) rule. In determining whether to list the NLEB, the Service looked to factor C of ESA section 4, which requires the Service to make a listing determination if “disease or predation” poses a threat to the species. The Service cited the impacts of white nose syndrome (WNS ...

On November 16, 2022, the U.S. District Court for the Northern District of California (District Court) remanded three sets of Endangered Species Act (ESA) regulations promulgated in 2019 under the Trump administration back to the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS) (collectively, Services) for reconsideration. The three regulations addressed: how species are listed and delisted and critical habitat designated under ESA section 4; interagency consultation under ESA section 7; and a final rule repealing USFWS’s blanket ESA ...

On November 7, 2022, the U.S. Fish and Wildlife Service (Service) proposed to designate approximately 595,495 acres of critical habitat for the Southern Sierra Nevada distinct population segment (DPS) of fisher (Pekania pennanti) under the Endangered Species Act (ESA). The critical habitat designation would span six units in California’s Tuolumne, Mariposa, Madera, Fresno, and Tulare Counties. The majority of the land comprising these units is owned and/or managed by federal, state, or tribal governments.

The fisher is a small, carnivorous mammal native to North American ...

On October 18, 2022, the U.S. Fish and Wildlife Service (Service) announced 12-month findings on a petition to list three California-based salamander species under the Endangered Species Act (ESA): the Kern Plateau salamander (Batrachoseps robustus), the Kern Canyon slender salamander (Batrachoseps simatus), and the relictual slender salamander (Batrachoseps relictus). All three salamander species occur in the southern Sierra Nevada Mountains in California. The Service determined that listing the Kern Canyon slender salamander and the relictual slender salamander is ...

Today, the U.S. Fish and Wildlife Service (Service) proposed to list two snake species, the Key ring-necked snake (Diadophis punctatus acricus) and the rim rock crowned snake (Tantilla oolitica), as endangered under the Endangered Species Act (ESA). The Service also proposed to designate critical habitat for these nonvenomous snakes, including approximately 2,604 acres in Monroe County and approximately 5,972 acres in Miami-Dade County and Monroe County, Florida for the Key ring-necked snake and rim rock crowned snake, respectively. The proposal comes as a result of a ...

On September 14, 2022, the U.S. Fish and Wildlife Service (Service) published a proposed rule to list the tricolored bat (Perimyotis subflavus) (TRBA) as an endangered species under the Endangered Species Act (ESA). The TRBA is known to occur in all or portions of 39 states across the northeast, as far south as southern Texas and Florida and as far west as Wyoming. Similar to the proposed rule to list the northern long-eared bat as endangered published earlier this year, the proposed rule cites white nose syndrome as the primary threat to the TRBA, but notes other factors influence the ...

On August 25, 2022, the U.S. Fish and Wildlife Service (Service) filed a stipulated settlement agreement (Agreement) in a case challenging the agency’s failure to timely make a 12-month finding on a petition to list the dunes sagebrush lizard (Scleroperus arenicolus) (Petition). Under the Agreement, the Service will submit a 12-month finding on the Petition to the Federal Register no later than June 29, 2023. The 12-month finding will determine whether listing the species is warranted (and will simultaneously issue a proposed rule to list the species), whether listing the ...

For the magnificent ramshorn (Planorbella magnifica), a fresh-water snail species native to southeastern North Carolina, efforts to secure protection under the federal Endangered Species Act have progressed at a snail’s pace. Today, twelve years after environmentalists originally petitioned the U.S. Fish and Wildlife Service (Service) to list the species, the Service proposed to list the magnificent ramshorn as endangered, and to designate two ponds spanning 739 acres as critical habitat for the species. The proposed rule was prompted by a lawsuit filed by the Center of ...

On July 27, 2022, the U.S. Fish and Wildlife Service (Service) published an advance notice of proposed rulemaking (ANPR) seeking comment on species conservation banking. Species conservation banking gives developers and other entities the opportunity to mitigate potential harm to wildlife by allowing them to purchase habitat or species credits from bank owners. The ANPR is a result of a provision in the 2021 National Defense Authorization Act (NDAA) that required the Service to issue regulations for species conservation banking programs. Although the ANPR stems from the NDAA ...

On July 5, 2022, the U.S. District Court for the Northern District of California issued an order vacating three Trump-era regulations implementing the Endangered Species Act (“ESA”).

In 2019, the U.S. Fish and Wildlife Service (“USFWS”) and the National Marine Fisheries Service (collectively, the “Services”) issued three final rules (“2019 ESA Rules”) modifying how the Services implement the ESA, including: (1) a rule under section 4 of the ESA concerning how the Services list, delist, and reclassify endangered or threatened species and the criteria for ...

On June 24, 2022, the U.S. Fish and Wildlife Service and the National Marine Fisheries Service (collectively, Services) published a final rule rescinding the Trump administration’s 2020 final rule defining “habitat” for the purpose of informing designation of areas as “critical habitat” (2020 Rule) under the Endangered Species Act (ESA). In rescinding the definition of “habitat,” the Services explained they were removing an “excessive constraint” on the agencies’ ability to designate critical habitat under the ESA. Specifically, the Services ...

On May 19, 2022, the Center for Biological Diversity (CBD) filed a lawsuit in the U.S. District Court for the District of New Mexico, challenging the U.S. Fish and Wildlife Service’s (Service) failure to make a timely 12-month finding on the group’s petition to list the dunes sagebrush lizard (Sceloporus arenicolus) (DSL), which was submitted to the agency in 2018.

The DSL is no stranger to controversy. In 2002, CBD and others petitioned the Service to list the DSL due to alleged threats to the species’ habitat caused by oil and gas production. In 2004, the Service determined that ...

On May 16, 2022, the U.S. District Court for the Northern District of California overturned the U.S. Fish and Wildlife Service’s (Service) March 31, 2020 withdrawal (2020 Withdrawal) of a proposed Endangered Species Act (ESA) listing and section 4(d) rule for the “bi-state population” of the greater sage grouse (Bi-state Grouse). The Bi-state Grouse lives along the California-Nevada border within six population management units (PMUs) monitored by the Service.   

The Service proposed the Bi-state Grouse for listing as threatened in 2013, then later withdrew that proposal ...

This week, the U.S. Fish and Wildlife Service (Service) issued a proposed rule to list the sand dune phacelia (Phacelia argentea) as threatened under the Endangered Species Act (ESA), along with a proposed section 4(d) rule that would prohibit several activities with respect to the species.  The proposed rule also includes a designation of approximately 252 acres of critical habitat in Del Norte County in California, and Coos and Curry Counties in Oregon.

On March 22, 2022, the Office of Information and Regulatory Affairs (OIRA) received from the U.S. Fish and Wildlife Service (Service) an Endangered Species Act (ESA)-specific compensatory mitigation policy (Policy). While the text of the Policy is not publicly available at this time, many have speculated that an updated Policy may mirror that which was in place under the Obama Administration.

On December 27, 2016, the Service published its final ESA Compensatory Mitigation Policy (2016 Policy) establishing the agency’s goal that compensatory mitigation provided under ESA ...

The U.S. Fish and Wildlife Service (Service) has announced its proposal to list the northern long-eared bat (Myotis septentrionalis) (NLEB) as endangered under the Endangered Species Act (ESA) (Proposed Rule). While Service policy indicates the agency should identify in a listing rule activities that would or would not result in a violation of the “take” prohibition set forth in section 9 of the ESA, the Service indicates in the Proposed Rule that it is unable to identify specific activities what would not violate the take prohibition. The Service points to the need for ...

Last Friday, the U.S. District Court for the Eastern District of California issued an order on competing motions in the coordinated cases challenging the 2019 biological opinions (BiOps) that govern operation of California’s State Water Project and the federal Central Valley Project (Projects). The hefty order, which spanned over a hundred and twenty pages, attempted to distill the thousands of pages of briefing the parties submitted on the matter. Admittedly, stakes were high: these two Projects supply water to more than 25 million Californians and to farmers across the ...

On February 9, 2022, the U.S. District Court for the District of Colorado found that the Bureau of Land Management (BLM) violated the Endangered Species Act (ESA) when it failed to reinitiate consultation with the U.S. Fish and Wildlife Service (Service) prior to approving oil and gas leases. BLM had issued the leases for parcels of land in Southwest Colorado located within Gunnison sage-grouse (Centrocercus minimus) habitat and other proposed and existing areas of environmental concern.

The ESA requires federal agencies to review federal actions “at the earliest possible time ...

Last week, a decision out of the U.S. District Court for the Northern District of California restored Endangered Species Act (ESA) protections for the gray wolf (Canis lupus) across most of the contiguous United States.

In 2020, the U.S. Fish and Wildlife Service (Service) issued a final rule removing federal protections for the last two remaining gray wolf entities listed as threatened or endangered under the ESA.  The final rule asserted delisting was warranted because neither the Minnesota entity nor the 44-state entity qualified as a species, subspecies, or 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 ...

The U.S. Fish and Wildlife Service (Service) has issued a final rule reclassifying the Morro shoulderband snail (Helminthoglypta walkeriana) from endangered to threatened under the Endangered Species Act (ESA). The final rule also includes a rule issued under ESA section 4(d) to provide for the conservation of the species.
