Endangered Species Law & Policy

On November 10, 2021, the U.S. Fish and Wildlife Service (USFWS) published a proposed rule to list the bracted twistflower (Streptanthus bracteatus), a plant species found only in Texas, as a threatened species under the Endangered Species Act (ESA).  The USFWS is proposing to list the bracted twistflower with a species-specific rule under section 4(d) of the ESA (4(d) rule), as well as to designate approximately 1,607 acres in central Texas as critical habitat for the species.

The bracted twistflower is a flowering annual plant and a member of the mustard family that can grow over ...

Today, the U.S. Fish and Wildlife Service (Service) published a final rule revising the critical habitat designation for the northern spotted owl (Strix occidentalis caurina) under the Endangered Species Act (ESA).  The final rule rescinds a previous rule issued by the Trump Administration on January 15, 2021, which was set to take effect this coming December, and would have excluded approximately 3.4 million acres from the species’ critical habitat designation.  Instead, the Service’s new final rule excludes from the designation only 204,294 acres located across multiple ...

Last week, the Center for Biological Diversity (CBD) filed suit against the U.S. Fish and Wildlife Service in the U.S. District Court for the Central District of California, alleging that the agency violated the Endangered Species Act (ESA) when it failed to timely determine whether the Santa Ana speckled dace (hinichthys osculus ssp.) and the Long Valley speckled dace (Rhinichthys osculus ssp.) warrant listing as endangered or threatened species. … 

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 October 14, 2021, the U.S. Fish and Wildlife Service (Service) issued a proposed rule to list the bog buck moth (Hemileuca maia menyanthevora) (= H.iroquois) as endangered under the Endangered Species Act (ESA). The Federal Register notice also states that the Service will make a final determination on the proposed listing within one year, and that it is seeking comments on the proposed designation.

The bog buck moth occurs in groundwater-fed wetlands in Oswego County, New York, and Ontario, Canada, with large amounts of bog buckbean (a plant that is a key food source, or “host plant” for bog buck moth larvae, much as milkweed is a host plant for monarch butterfly larvae). …

On October 18, 2021, the U.S. Fish and Wildlife Service (Service) issued a final rule reclassifying the humpback chub (Gila cypha), a fish endemic to portions of the Colorado River basin, from endangered to threatened under the Endangered Species Act (ESA).  The Service attributed the chub’s status upgrade largely in part to modifications in how reservoir managers are operating their facilities, and the management of nonnative predators.

The chub was first listed as an endangered species in 1967 under the Endangered Species Preservation Act, a predecessor to the ESA.  In 1974, the ...

In the last few weeks, the U.S. Fish and Wildlife Service (Service) has published several major regulatory actions affecting federal avian protections.  The Service has repealed a Trump-era rule that excluded incidental take from liability under the Migratory Bird Treaty Act (MBTA), issued guidance for enforcement of the MBTA against incidental take, and invited comment on a potential MBTA permitting program.  Separately, the Service has invited comment on ways to improve its existing permitting program for the incidental take of eagles (Eagle Permit Program). … 

On October 7, 2021, the Council on Environmental Quality (CEQ) will publish the first of two proposed rulemakings to revise National Environmental Policy Act (NEPA) regulations that had previously been updated in 2020 under the Trump Administration. As stated by CEQ in the proposal, the agency intends to “generally restore” NEPA regulations that were in place prior to the 2020 updates.

In this first phase of NEPA regulatory revisions, CEQ addresses the agency’s definition of “purpose and need,” the definition of “effects” of the action, and agency procedures for ...

Last week, the U.S. Fish and Wildlife Service (Service) published two proposed rules to delist a total of 24 species under the Endangered Species Act (ESA).  First, the Service published a proposed rule delist 23 species as a result of the species’ extinction.  The 23 now-extinct species include thirteen species of birds, eight freshwater mussels, one Texas fish, and one Hawaiian plant.  The Federal Register notice indicates that, based on the best available scientific and commercial data, these species are no longer extant, and therefore no longer meet the definitions of ...

This week, the U.S. Fish and Wildlife Service (USFWS) issued three separate notices in the Federal Register concerning the agency’s 12-month findings on a number of petitions to list various wildlife and plants under the Endangered Species Act (ESA).

First, the USFWS announced a positive 12-month finding on a petition to list the Peñasco least chipmunk (Neotamias minimus atristriatus), a small mammal from New Mexico.  The USFWS proposes to list the Peñasco least chipmunk as an endangered species under the ESA and to designate approximately 6,574 acres of land as critical ...

On September 20, 2021, the U.S. District Court for the Central District of California set aside the U.S. Fish and Wildlife Service’s (Service) negative 12-month finding (Finding) on a petition by WildEarth Guardians (Guardians) to list the Joshua tree (Yucca brevifolia) as threatened under the Endangered Species Act (ESA).

The petition had alleged that the Joshua tree is threatened by the effects of climate change and its associated effects, including drought and increasing wildfires. On September 14, 2016, the Service issued a positive finding on Guardians’ petition ...

Today, the U.S. Fish and Wildlife Service (Service) announced its 90-day findings on petitions to list two proposed distinct population segments (DPS) of the gray wolf (Canis lupus) as threatened or endangered under the Endangered Species Act (ESA): a Northern Rocky Mountains DPS and a Western United States DPS. The Service determined that listing may be warranted, and announced its intention to initiate a status review for these populations of the species.

In 1978, except for the Minnesota population, the gray wolf was listed as an endangered species throughout the ...

On September 8, 2021, the U.S. Fish and Wildlife Service ("USFWS") published a final rule in the Federal Register listing the slenderclaw crayfish as endangered under the Endangered Species Act ("ESA") and identifying approximately 78 miles of river in DeKalb and Marshall Counties, Alabama as critical habitat for the species.

The slenderclaw crayfish is a small freshwater crustacean that is endemic to streams on Sand Mountain within the Tennessee River Basin in Alabama. Most of the slenderclaw crayfish’s natural habitat was flooded when the Tennessee River was dammed in 1939 to ...

The U.S. Fish and Wildlife Service (Service) recently listed the Franklin’s bumble bee as an endangered species under the Endangered Species Act.  Historical records indicate that the species is endemic to southwest Oregon and northern California.  The last known record of the species dates back to 2006.  The Service’s decision is the culmination of a listing process that began 11 years ago with the submission of a petition to list by the Xerces Society in 2010.

In its press release announcing the decision, the Service both noted that Franklin’s bumble bee has the smallest known ...

On August 18, 2021, the U.S. Fish and Wildlife Service (“Service”) published in the Federal Register a final rule designating more than 1,315 acres across 14 units as critical habitat (“Final Rule”) for two neotenic salamander species known only from Williamson and Bell Counties, Texas: the Georgetown salamander (Eurycea naufragia) and Salado salamander (Eurycea chisholmensis).  The species are “neotenic” because they do not transform into a terrestrial form and instead spend their entire life cycle in water.  The Final Rule was published in accordance with a ...

Today, the U.S. Fish and Wildlife Service (“Service”) published in the Federal Register a proposal to list six Central Texas mussel species under the Endangered Species Act (“ESA”), to issue an ESA section 4(d) rule for one of the species, and to designate critical habitat (“Proposed Rule”).  Specifically, the Service has proposed to list the Guadalupe fatmucket (Lampsilis bergmanni), Texas fatmucket (Lampsilis bracteata), Guadalupe orb (Cyclonaias necki), Texas pimpleback (Cyclonaias (=Quadrula) petrina), and false spike (Fusconaia (=Quincuncina) mitchelli) as endangered ... 

On Monday, the U.S. Fish and Wildlife Service (FWS) published a final rule delisting the now-recovered Cumberland sandwort (Arenaria cumberlandensis) under the Endangered Species Act (ESA).  Originally listed as endangered in 1988, the Cumberland sandwort is a perennial plant species occurring in cave-like “rockhouses” or bluff sites throughout northern Tennessee and southern Kentucky.  In 1996, the FWS released a recovery plan for the species.  By December of 2013, the FWS recommended downlisting the Cumberland sandwort to threatened status, and in April of 2020, the ...

Last Friday, the U.S. Fish and Wildlife Service (“USFWS”) finalized the removal of the now-recovered Trifolium stoloniferum (running buffalo clover) from the list of endangered and threatened wildlife and plants protected under the Endangered Species Act (“ESA”).  Running buffalo clover is a perennial species with small white flowers and leaves divided into three leaflets.  The plant produces creeping stems that “run” along the surface of the ground to re-root and form new clusters of clover.

The USFWS initially listed the running buffalo clover as an endangered ...

This week, the U.S. Fish and Wildlife Service (FWS) published a 12-month finding on a petition to revise the critical habitat designation for the endangered Mount Graham red squirrel (Tamiasciurus hudsonicus grahamensis) under the Endangered Species Act (ESA).  The Mount Graham red squirrel is a subspecies of red squirrel occurring only in certain high-elevation areas of the Coronado National Forest in Arizona. 

In December of 2017, a group of eNGOs including the Center for Biological Diversity submitted a petition to FWS, requesting that the agency expand the subspecies’ ...

Earlier this week, the U.S. Fish and Wildlife Service (Service) published a Federal Register notice addressing 90-day findings for three separate species.  With the notice, two species moved one step closer to being listed under the federal Endangered Species Act (ESA).

In July of 2020, the Service received a petition to list the Alexander Archipelago wolf (Canis lupus ligoni) as an endangered or threatened species.  The wolf’s current range includes Alaska and Canada.  The Service concluded in the 90-day finding that listing may be warranted due to potential threats associated ...

This week, the U.S. Fish and Wildlife Service (“USFWS”) announced the availability of two revised economic analysis documents related to the agency’s proposed rule concerning incidental take under the Migratory Bird Treaty Act (“MBTA”).  The documents evaluate the potential for the proposed rule to impact small entities, including businesses, governmental jurisdictions, and other organizations.

When federal agencies issue a new proposed or final rule, they are required under the Regulatory Flexibility Act of 1980 (“RFA”) to evaluate the potential effects ...

On July 13, the U.S. Fish and Wildlife Service (Service) published a proposed rule to designate critical habitat for the pearl darter (Percina aurora) under the federal Endangered Species Act (ESA).  Listed as a threatened species under the ESA in September 2017, the pearl darter is a small, snub-nosed fish whose historical range includes Mississippi and Louisiana.  The proposed critical habitat designation for the pearl darter includes a total of approximately 517 river miles along the Pascagoula River and Pearl River basins, which run across multiple counties in ...

On July 7, 2021, the U.S. Fish and Wildlife Service (FWS) published a proposed rule in the Federal Register announcing the agency’s finding that the razorback sucker (Xyrauchen texanus) no longer warrants listing as an endangered species under the federal Endangered Species Act (ESA). As such, FWS has proposed to downlist the species to threatened status.

The razorback sucker is a freshwater fish measuring up to 3 feet long that gets its name from the bony ridge behind its head. The species is commonly found throughout the reservoirs, floodplains, and backwaters of the Colorado ...

The American Bar Association has published a newly revised edition of its tome Endangered Species Act: Law, Policy, and Perspective.  Editors Don Baur and Jake Li pulled together leaders in the field from government, the private sector, and non-profits who penned 18 chapters covering all aspects of the Endangered Species Act (ESA) and its implementation.  The volume also covers related topics including state-level and international efforts to protect wildlife.

Steve Quarles, Paul Weiland, and Brian Ferrasci-O’Malley contributed a chapter in the volume on the prohibitions ...

On June 7, 2021, the U.S. Supreme Court (“SCOTUS”) agreed with the Department of Justice and declined to hear a case brought by the Kansas Natural Resource Coalition (Coalition) challenging the U.S. Fish and Wildlife Service’s (Service) failure to submit the Policy for the Evaluation of Conservation Efforts (PECE) Policy to Congress under the Congressional Review Act (CRA).  The case, which represents a unique intersection between the lesser prairie-chicken (Tympanuchus pallidicinctus) (LEPC), the Service’s PECE Policy, and the CRA, appears to foreclose the ability ...

In a per curiam decision, the United States Court of Appeals for the D.C. Circuit dismissed the Center for Biological Diversity’s (CBD) challenge to the Fish and Wildlife Service’s (Service) process for assessing the status of species to inform regulatory decisions with respect to those species.  That process, referred to as species status assessment (SSA), is akin to a biological risk assessment for the target species.  It has been developed by the Service over the past several years and provides a more structured approach to assessing listing, delisting, uplisting, and ...

This week, I published a post on the Center for California Water Resources Policy and Management’s DeltaCurrents blog discussing the role of conceptual ecological models in implementing the federal Endangered Species Act. Conceptual ecological models are a specialized subset of conceptual models generally intended to describe the environmental factors that affect an ecological community, a species, or a population. Conceptual ecological models are useful in a variety of contexts ranging from development of research proposals and monitoring schemes, to regulatory ...

Recently, the Department of the Interior released a pre-publication version of a Federal Register notice delaying the effective date of the Migratory Bird Treaty Act (MBTA) take definitional rule to March 8, 2021, and opening a 20-day public comment period, which will close March 1, 2021.  The MBTA was enacted in 1918 to implement an international convention for the protection of migratory birds in response to declines in populations of a number of species of birds resulting from widespread hunting and poaching.  The take definitional rule states in full:

“The prohibitions of the ...

On January 20, 2021, President Biden announced his administration will review regulatory actions taken between January 20, 2017 and January 20, 2021 in accordance with an Executive Order titled “Protecting Public Health and the Environment and Restoring Science to Tackle the Climate Crisis” (EO). Among the agency actions to be reviewed under the EO are a number of regulations and policies finalized by the Trump Administration involving Endangered Species Act (ESA), Migratory Bird Treaty Act (MBTA), and other related statutes.

An initial pre-publication announcement ...

On December 31, 2020, the National Marine Fisheries Service (“NMFS”) proposed to amend regulations implementing the Atlantic Large Whale Take Reduction Plan (“ALWTRP” or “Plan”) with the stated goal of reducing the incidental mortality and serious injury to the endangered North Atlantic right whale, as well as fin whales and humpback whales, in the Northeast commercial lobster and crab trap/pot fisheries. The agency stated that the amendment is needed in order to comply with the Marine Mammal Protection Act (“MMPA”) and the Endangered Species Act (“ESA” ...

On December 17, 2020 the U.S. Fish and Wildlife Service (“USFWS”) published its 12-month finding that listing of the monarch butterfly (Danaus plexippus plexippus) is warranted but precluded by higher priority actions. With this finding, the monarch becomes a candidate species with a listing priority designation of “8.”  An “8” indicates the magnitude of threats to the monarch is moderate to low and those threats are imminent. In the announcement, the USFWS notes that 161 other species are currently prioritized above the monarch for listing consideration. Each year ...

On December 15, 2020, the U.S. Fish and Wildlife Service and National Marine Fisheries Service (collectively, the agencies) released a pre-publication version of a final rule providing a definition of “habitat” for the purpose of informing designation of areas as “critical habitat” under the Endangered Species Act.  The agencies released a proposed rule defining habitat in August 2020 in response to a unanimous decision by the U.S. Supreme Court in 2019 overturning a lower court decision that upheld a controversial determination of critical habitat by the U.S. Fish and ...

On May 5, 2020, the United States Fish and Wildlife Service (FWS) decided to list the island marble butterfly (Euchloe ausonides insulanus) as an endangered species under the Endangered Species Act (ESA).  The FWS decision also designated approximately 812 acres of critical habitat for the species on the south end of San Juan Island, San Juan County, Washington.

Until 1998 when the species was rediscovered on San Juan Island, the island marble butterfly was thought to be extinct because no known occurrences of the species were documented after 1908. In 2006, the FWS issued a 12-month ...

The sweeping and rapid ascent to popularity of Netflix Inc.'s "Tiger King" documentary series has fueled new interest in two congressional bills that stalled in committee last year, and has drawn public attention to a quirk of the Endangered Species Act, or ESA.

I recently authored the article, "'Tiger King' Shines Light on an Endangered Species Act Quirk" for Law360. This piece examines ...

On April 15, 2020, the U.S. District Court for the District of Montana issued an order that could impact energy and development projects across the United States. The court granted partial summary judgment in favor of plaintiff the Northern Plains Resource Council (“NPRC”) in a case concerning challenges to the Keystone XL Pipeline.  While the case mostly focused on the permitting for this particular pipeline, the nature of the claims raised resulted in broader implications for nationwide permit (“NWP”) 12, an important nationwide permit issued by the U.S. Army Corps of ...

On April 8, 2020 the U.S. Fish and Wildlife Service (Service) announced its next step in conservation of the Monarch butterfly (Danaus plexippus plexippus): finalization of the Nationwide Candidate Conservation Agreement for Monarch Butterfly on Energy and Transportation Lands (Monarch CCAA/CCA). The Monarch CCAA/CCA functions as both a candidate conservation agreement with assurances (CCAA) covering non-federal lands and a candidate conservation agreement (CCA) covering federal lands.

Authorized by Endangered Species Act (ESA) regulations, CCAAs are agreements ...

The U.S. Fish and Wildlife Service (Service) has withdrawn its 2013 proposals to list the bi-state distinct population segment of the greater sage-grouse (Centrocercus urophasianus) in California and Nevada as threatened, to designate critical habitat, and to issue a species-specific Endangered Species Act section 4(d) rule. The Service indicated in its withdrawal that the agency has concluded that threats to the species were not as significant as the agency believed in 2013.

The listing, critical habitat, and 4(d) rules for the bi-state distinct population segment of the ...

On February 19, 2020, the U.S. Bureau of Reclamation issued a Record of Decision (ROD) on the reinitiation of consultation on the coordinated long-term operations of the Central Valley Project and State Water Project.  At the same time, the President signed a memorandum on developing and delivering more water supplies in California. The Department of the Interior issued a press release describing these actions. 

The execution of the ROD signals the shift from operations of the Central Valley Project and State Water Project under the biological opinions issued by the U.S. Fish and ...

On February 5, 2020, the National Marine Fisheries Service (NMFS) issued its 12-month finding on the petition to list summer-run steelhead in Northern California (Oncorhynchus mykiss irideus) as endangered under the Endangered Species Act (ESA), concluding that listing is not warranted because the summer-run steelhead does not qualify as a distinct population segment of the Northern California steelhead. Despite the negative finding, the summer-run steelhead is still protected under the ESA. How is that possible, you ask?

Simple, I say. The summer-run and winter-run ...

On January 28, 2020, the U.S. Fish and Wildlife Service (USFWS) published a notice and request for information in connection with USFWS’s initiation of 5-year status reviews for 66 species found in California and Nevada.  Among the species subject to review are the bay checkerspot butterfly (Euphydryas editha bayensis), Sierra Nevada yellow-legged frog (Rana sierra), the California tiger salamander (Ambystoma californiense), Morro Bay kangaroo rat (Dipodomys heermanni morroensis), and many other plants and wildlife species.  A full list of species subject to the 5-year ...

On Tuesday, January 14, 2020, the U.S. Fish and Wildlife Service (Service) published a federal register notice that it will be commencing a comprehensive study of the status of the Grizzly bear (Ursus arctos horribilis).  This study, called a 5-year status review, could lead to a change in the bear’s status as a protected species under the Endangered Species Act (ESA).  This 5-year review was spurred by a lawsuit filed by the Center for Biological Diversity, which alleged that the Service failed to complete the required status review on time.  The Service and Center for Biological ...

On January 15, 2020, the United States Court of Appeals for the Fifth Circuit reversed a lower court decision that upheld the determination of the U.S. Fish and Wildlife Service (Service) denying a petition to delist the Golden-Cheeked Warbler (Setophaga chrysoparia) (Warbler). The Service listed the Warbler as an endangered species under the Endangered Species Act (ESA) in 1990, initially on an emergency basis.

The petition to delist the Warbler was submitted to the Service in 2015 by a group of petitioners that included the General Land Office of the State of Texas. The petition ...

In a recent opinion, the United States Court of Appeals for the Ninth Circuit reversed in part the United States District Court for the Eastern District of California’s grant of summary judgment to the National Marine Fisheries Service (“NMFS”) in Friends of the River v. NMFS, No. 18-15623 (9th Cir. Oct. 3, 2019).

Plaintiff Friends of the River (“FOR”) challenged (1) NMFS’ decision to characterize the existence of federally-managed dams on the Yuba River as part of the environmental baseline in a 2014 BiOp and Letter of Concurrence (“LOC”) issued to the Corps for the ...

On September 26, 2019, the U.S. District Court for the District of Colorado vacated and remanded in part the U.S. Fish and Wildlife Service’s (Service) 2014 determination that listing the Rio Grande cutthroat trout (Oncorhynchus clarki virginalis) under the Endangered Species Act (ESA) was not warranted.

The Rio Grande cutthroat trout is native to high-altitude streams in southern Colorado and New Mexico. In 2008, the Service determined that the Rio Grande cutthroat trout warranted listing as an endangered or threatened species, although listing was precluded by other higher ...

On August 6, 2019, the U.S. Fish and Wildlife Service (FWS) published a 90-day finding that listing the Yellowstone Park bison (Bison bison bison) under the Endangered Species Act is not warranted. FWS also found that listing the Mojave poppy bee (Perdita meconis) and revising the critical habitat designation for the endangered Mount Graham red squirrel (Tamiasciurus hudsonicus grahamensis) may be warranted ...
