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 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 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 December 10, 2021, the Biden Administration released the Fall 2021 Unified Agenda of Regulatory and Deregulatory Actions (Unified Agenda), which is a semi-annual compilation of information concerning regulations and policy under development by federal agencies. Department of the Interior (DOI) entries on the Unified Agenda reveal a lengthy set of planned regulatory actions, some of which may have an impact on development and deployment of energy, construction and operation of transportation and other infrastructure, and various other economic activities. … 

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 ...

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 ...

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 ...

In the first week of May, the U.S. Fish and Wildlife Service (“USFWS”) and the National Marine Fisheries Service (“NMFS”) proposed rules to remove six species from the lists of endangered and threatened wildlife and plants under the Endangered Species Act (“ESA”).

On May 4, 2021, NMFS issued a proposed rule to remove Siderastrea glynni, a coral originally found at Urabá Island, Panama Gulf, from the ESA lists.  The coral was first discovered in 1992 and was initially thought to be the only extant Siderastrea species in the eastern Pacific Ocean.  NMFS received a petition to ...

On January 13, 2021, the U.S. Fish and Wildlife Service (Service) published a final rule to remove the inland population of the Interior least tern (Sterna (now Sternula) antillarum) from the list of endangered and threatened wildlife under the Endangered Species Act (ESA).  Originally listed as an endangered species under the ESA in 1985, the Interior least tern is a small, fish-eating bird occurring along the Arkansas, Ohio, Mississippi, Missouri, Red, and Rio Grande rivers.  

Prior to listing, the Interior least tern’s population had fallen below 2,000 as a result of habitat ...

Linear infrastructure projects, including oil and gas pipelines, electric transmission lines and transportation, have faced a number of regulatory challenges over the past year, starting with last summer’s Endangered Species Act (ESA) amendments. Some of these challenges stem from changes in regulatory schemes or adverse court holdings, while others stem from uncertainty of pending ESA listing decisions and other actions. 

In our recent webinar concerning Adapting Linear Infrastructure Projects to Changing Regulatory Frameworks, we discussed the path for energy providers to move forward and reduce the risk that projects may be delayed or scrapped down the road. One of the topics we covered was the 2019 regulatory amendments to the Endangered Species Act (ESA). In the following video clip from the webinar, we review some of the revised definitions and updated language in the new version of the regulations.

If you would like to view the full webinar ...

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 ...

On January 6, 2020, the U.S. Fish and Wildlife Service (FWS) published a proposed rule in the Federal Register announcing the agency’s finding that the Kanab ambersnail (Oxyloma haydeni kanabensis) is no longer warranted for listing as an endangered species under the federal Endangered Species Act (ESA). The proposed rule states that the Kanab ambersnail does not represent a valid taxonomic entity, and therefore does not meet the definition of “species” under the ESA. The ESA defines “species” as including ''any subspecies of fish or wildlife or plants, and any distinct population segment of any species of vertebrate fish or wildlife which interbreeds when mature.”

The Kanab ambersnail, which gets its name from its mottled, amber-colored shell, is a terrestrial snail ...

On September 13, 2019, the U.S. Fish and Wildlife Service (Service) posted a final rule removing the Foskett speckled dace (Rhinichthys osculus ssp.) from the federal List of Endangered and Threatened Wildlife.  The dace, which was listed under the Endangered Species Act (ESA) as a threatened species in 1985, is being removed from the List of Threatened and Endangered Species on the basis of recovery.  In its final notice, the Service indicates that the threats to the dace have been “eliminated or reduced to the point where [the dace] no longer meets the definition of an endangered or ...

The U.S. Fish and Wildlife Service (USFWS) is systematically revising species recovery plans issued under the Endangered Species Act (ESA).  On August 6, 2019, USFWS published three notices of availability announcing public comment periods on its draft revisions to 70 recovery plans covering 121 species across the United States ...

In its newly-released proposed recovery plan for the Desert pupfish (Cyprinodon macularius), the U.S. Fish and Wildlife Service (Service) has put into action its internal plan to add quantitative criteria to recovery plans.  The pupfish recovery plan, originally adopted in 1993, contained only qualitative criteria when adopted.  In its proposed revisions to the pupfish’s recovery plan, the Service adds quantitative criteria for whether the pupfish should be considered for delisting or when it has recovered, including the number of established populations that would make the ...

Today, the U.S. Fish and Wildlife Service (Service) finalized its reclassification of the Tobusch fishhook cactus (Sclerocactus brevihamatus ssp. tobuschii), a small cactus found in Texas, downlisting the species from endangered to threatened under the Endangered Species Act (ESA).

As previously reported here, the Service concluded that downlisting the cactus was warranted given an increase in the number of observed individuals. While only 200 cactuses were known when the species was listed as endangered in 1979, the Service now estimates there are more than 3,300 ...

On April 17, 2018, the U.S. Fish and Wildlife Service (Service) reached a negative 90-day finding on a petition to remove the Preble’s meadow jumping mouse (Zapus hudsonius preblei) from the List of Threatened and Endangered Species.  The Service’s finding was in response to a petition to delist the mouse filed by the Pacific Legal Foundation in 2017.  The Service concluded that the petition presented no new information indicating that delisting the mouse is warranted.

The Service rejected the petition’s taxonomic argument that the mouse is not a distinct subspecies that ...

On February 27, 2018, the U.S. Fish and Wildlife Service (FWS) finalized a regulation removing Eureka Valley evening-primrose (Oenothera californica ssp. eurekensis) from the Federal List of Endangered and Threatened Plants.  The delisting, originally proposed in 2014, is based on the elimination of threats to the subspecies, accomplished largely as a result of the 1994 designation and ongoing management of its dune habitat as federal wilderness within Death Valley National Park.  The National Park Service manages the federal wilderness area under the Park Service’s Organic ...

On Friday, September 29, 2017, the U.S. Fish & Wildlife Service (Service) announced its withdrawal of the proposed rule listing the Kenk’s amphipod (Stygobromus kenki), an aquatic crustacean, as an endangered species under the Endangered Species Act (ESA).  The Service originally proposed to list the amphipod, which occurs in the District of Columbia, Virginia, and Maryland, in September 2016 due to the impacts of water quality, water quantity, and other collateral impacts of urbanization near the species’ habitat.  In support of its decision to withdraw the proposed ...

On June 23, 2017, the U.S. Fish and Wildlife Service (Service) promulgated a long-awaited final rule to delist the Hualapai Mexican vole (Microtus mexicanus hualpaiensis) (HMV) due to the Service’s determination that the original 1987 listing of the HMV under the Endangered Species Act (ESA) was in error.  Based upon more recent scientific and commercial information, the Service concluded that the HMV is not a distinguishable subspecies of Mexican vole and thus is not a valid taxonomic entity listable under the ESA.  This error in taxonomic classification was first raised by a ...

On June 22, 2017, U.S. Secretary of the Interior Ryan Zinke announced that the U.S. Fish and Wildlife Service (Service) will delist the Yellowstone population of the grizzly bear (Ursus arctos horribilis).  According to the Service, the Greater Yellowstone Ecosystem Distinct Population Segment (Yellowstone DPS) of the grizzly bear has recovered to the point that federal protections are no longer necessary and overall management of the species can be returned to the states and tribes.

The Yellowstone DPS consists of grizzlies in portions of northwestern Wyoming, southwestern ...

Earlier this week, the U.S. Fish & Wildlife Service (Service) issued a notice in the Federal Register that it was reopening the comment period on five proposed rules for four plant species.  Specifically, the proposed rules include the following: (1) listing Guadalupe fescue (Festuca ligulata) as an endangered species; (2) designating Guadalupe fescue critical habitat; (3) reclassifying Tobusch fishhook cactus (Sclerocactus brevihamatus ssp. tobuschii) from endangered to threatened; (4) reclassifying Kuenzler hedgehog cactus (Echinocereus fendleri var.

On February 27, 2017, the California Supreme Court reversed a Court of Appeal decision dismissing a petition for writ of mandate regarding the California Fish and Game Commission’s (Commission) rejection of a petition to delist the population of coho salmon (Oncorhynchus kisutch) south of San Francisco under the California Endangered Species Act (CESA).  Central Coast Forest Assoc. v. Fish and Game Comm’n, Case No. S208181, 2017 Cal. LEXIS 1540 (Cal. Feb. 27, 2017).  The California Supreme Court held that the Court of Appeal erred by failing to consider the merits of the ...

On December 28, 2016, the U.S. Fish and Wildlife Service (Service) published a proposed rule to reclassify the Tobusch fishhook cactus (Sclerocactus brevihamatus ssp. tobuschii), downlisting the species from endangered to threatened under the Endangered Species Act (ESA).  The Service concluded that, while the Cactus is not in danger of extinction, it is likely to become endangered in the foreseeable future.  This proposed rule and the accompanying 12-month finding were precipitated by the same ESA petition, citizen suit, and settlement agreement that compelled the ...

On January 20, 2015, the Senate Committee on Environment and Public Works approved S. 659, the Bipartisan Sportsmen’s Act of 2015, which complements the bill reported by the Senate Energy and Natural Resources Committee late last year.  However, the Environment and Public Works Committee’s approval adds a number of controversial amendments to the Act’s overarching purpose of increasing recreational hunting, fishing, shooting, conservation, and other access on public lands.  An amendment offered by Senator John Barrasso (R-Wyo.), and approved by voice vote, would delist ...

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 ...

The Modoc sucker (Catostomus microps), a small fish with a range limited to northeast California and south-central Oregon, was listed as endangered (pdf) in 1985.  A recovery plan for the species was adopted by the Service in 1992, and in February 2014, the Fish and Wildlife Service proposed the delisting of the species (pdf).  In the proposed rule, the Service made the following determinations:

As a result of the discovery of five populations not known at the time of listing and the documentation of the genetic integrity of populations considered in the 1985 listing rule to have been lost ...

Continuing the quarter century controversy over the listing of the Coastal California gnatcatcher (Polioptila californica californica) as a threatened subspecies, the U.S. Fish & Wildlife Service (FWS) has concluded that a petition to delist the gnatcatcher may be warranted. (Federal Register PDF).   The petition asserts that the listing of the Coastal California gnatcatcher as a distinct subspecies is not based on the best scientific data available as is required by the Endangered Species Act.  Nossaman prepared the petition on behalf of the National Association of Home ...

On September 17, 2014, the U.S. Fish and Wildlife Service (Service) withdrew (pdf) its proposal (pdf) to remove the valley elderberry longhorn beetle (Desmocerus californicus dimorphus) from the Federal List of Threatened and Endangered Species.  While this means the beetle will continue to be protected as a threatened species under the Endangered Species Act (ESA), the Service did reduce the area in which the species is presumed to occur.

The beetle was listed as threatened and critical habitat designated, in 1980 (pdf).  Until recently, the beetle’s range was believed to ...

Citing new genetic evidence that the coastal California gnatcatcher is not a distinct subspecies as previously claimed, but is part of a single, healthy and abundant species that ranges from Southern California to the southern tip of Baja, Mexico, the National Association of Home Builders and several other parties filed a petition to remove the coastal California gnatcatcher from the list of threatened species.  The petition to the U.S. Fish and Wildlife Service (Service) is based on a peer-reviewed study of gnatcatcher DNA by Dr. Robert Zink of the University of Minnesota and ...

On February 26, the Alaska Department of Fish and Game petitioned (pdf) the National Marine Fisheries Service (NMFS) to remove the Central North Pacific subpopulation of humpback whales from the federal list of endangered or threatened species. In a press release, the director of Alaska’s Division of Wildlife Conservation declared the species a prime example of a recovered species that should be delisted from the Endangered Species Act (ESA) because the threat of extinction for this subpopulation is gone.

The entire North Pacific humpback whale species (Megaptera ...

 The U.S. Fish and Wildlife Service (Service) recently issued (pdf) a proposed rule to remove Eureka Valley evening-primrose (Oenothera avita ssp. eurekensis) and Eureka dune grass (Swallenia alexandrae) from the federal list of endangered species. The Service’s proposed rule follows its 12-month finding on the Pacific Legal Foundation’s petition to delist the species.

Eureka Valley evening-primrose and Eureka dune grass are endemic to three dune systems in the Eureka Valley, located in Inyo County, California. Eureka Valley is managed by the National Park Service (Park ...

In August 2008, the U.S. Fish and Wildlife Service (Service) issued a proposed rule to delist the Hawaiian hawk (Buteo solitarius), also referred to as the io, from the federal list of endangered or threatened species.  The proposed rule states that the proposed action is "based on a thorough review of the best available scientific data, which indicates that range-wide population estimates have been stable for at least 20 years, and the species has recovered and is not likely to become an endangered species in the foreseeable future throughout all or a significant portion of ...

A report issued by a group of independent scientists claims that the U.S. Fish and Wildlife Service (Service) relied on inadequate scientific evidence to support its proposal to delist the gray wolf (Canis lupus) under the Endangered Species Act (ESA). As we previously reported, the Service issued a proposed rule to delist the species last June. The Service then commissioned U.C. Santa Barbara’s National Center for Ecological Analysis and Synthesis (NCEAS) to conduct an independent review of the science behind the proposed rule. NCEAS issued its report last month.

According ...

As recently reported in The Oregonian, the U.S. Fish and Wildlife Service (Service) has declared the Oregon chub (Oregonichthys crameri) recovered, and will remove the species from the list of federally threatened and endangered species.  According to the report, this is the first fish ever taken off the endangered species list.  In a previous report, the Service stated that the fish's improved status was attributable to the efforts of the Oregon Chub Working Group, and "successful introduction of Oregon chub into new locations within their historical range and the discovery ...

Last week, the Interagency Grizzly Bear Committee, a panel consisting of federal, state, local, and tribal representatives, recommended that the U.S. Fish and Wildlife Service (Service) remove the grizzly bear (Ursus arctos horribilis) from the list of threatened and endangered species under the Endangered Species Act (ESA). If the Service agrees, it will initiate the rule-making process to delist the species. The Service is expected to make a decision next month.

The Yellowstone grizzly bear population is found in Montana, Idaho and Wyoming. When initially listed under the ...

On November 4, 2013, the U.S. Fish and Wildlife Service (Service) published a proposed rule (pdf) to remove the Inyo California towhee (Pipilo crissalis eremophilus) from the list of threatened and endangered species under the Endangered Species Act (ESA). The Service concluded that delisting the Inyo California towhee is warranted because substantial threats to the species have been ameliorated or reduced since listing, and the species no longer meets the definition of a threatened species under the ESA. 

According to the Service, the total rangewide population of the towhees ...

Last week, the National Marine Fisheries Service (NMFS) issued a final rule (pdf) delisting the eastern distinct population segment (DPS) of the Steller sea lion (Eumetopias jubatus) from the list of threatened and endangered species. NMFS concluded that delisting is warranted because the species has met the recovery criteria outlined in its 2008 recovery plan and no longer meets the definition of a threatened or endangered species under the Endangered Species Act (ESA).

According to NMFS, the eastern DPS Steller sea lion population has increased from an estimated 18,040 ...

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 ...

On June 13, 2013, the U.S. Fish and Wildlife Service (Service) issued a proposed rule (pdf) to delist the gray wolf (Canis lupus) under the Endangered Species Act (ESA) throughout the United States and Mexico. The proposed rule also proposes to maintain protection for the Mexican gray wolf (Canis lupus baileyi) in the Southwest by listing it as endangered under the ESA. Presently, the gray wolf is listed in 42 states, including California. 

Previously, the Service determined (pdf) that the southwestern population of the gray wolf – known as the Mexican gray wolf – may warrant a ...

On June 5, 2013, the U.S. Fish and Wildlife Service (Service) denied (pdf) two petitions to remove captive populations of the scimitar-horned oryx (Oryx dammah), dama gazelle (Gazella dama), and addax (Addax nasomaculatus) from the List of Endangered and Threatened Wildlife under the Endangered Species Act (ESA). In denying the petitions, the Service found it did not have the discretion to differentiate the listing status of animals in captivity from those in the wild.

The petitions, brought by Safari Club International and the Exotic Wildlife Association, sought to delist only ...

On May 15, 2013, the U.S. Fish and Wildlife Service (Service) removed (pdf) the Magazine Mountain shagreen (Inflectarius magazinensis) from the Federal List of Endangered and Threatened Wildlife. The Service determined that the threats to the species have been eliminated or reduced to the point that the species has recovered and no longer meets the definition of threatened or endangered under the Endangered Species Act (ESA).

The Magazine Mountain shagreen is a medium-sized, dusky brown or sand-colored snail found on Mount Magazine in western Arkansas. The snail was first listed ...

The U.S. Fish and Wildlife Service (Service) recently proposed (pdf) to remove the island night lizard (Xantusia riversiana) from its current listing as threatened under the Endangered Species Act (ESA).  The proposed removal is based on successful recovery efforts led by the U.S. Navy and National Park Service, which have resulted in the achievement of nearly all of the objectives established in the recovery plan for the species.

Island night lizards are found only on the Channel Islands - San Clemente Island, San Nicolas Island, and Santa Barbara Island - off the ...

In Central Coast Forest Assoc. v. California Fish and Game Commission (pdf), the California Court of Appeal, Third Appellate District held that a petition to delist the endangered coho salmon (Oncorhynchus kisutch) under the California Endangered Species Act (CESA), fails at the outset because a petition to delist a species may not be employed to challenge a final determination of the Commission.  The 2-1 decision is one of a small number of reported cases to interpret the listing provisions of the California Endangered Species Act (CESA).  The decision has important state-wide ...

On Tuesday, December 18, 2012, the U.S. Fish and Wildlife Service (Service) proposed upgrading the status of the wood stork (Mycteria americana) from endangered to threatened under the Endangered Species Act (ESA).  The proposed change is in response to improvements in the population and habitat of the species based on the best available scientific information.

Dan Ashe, Director for the Service, remarked that the proposed reclassification "demonstrates that the [ESA] works" and that "the species is making real progress toward recovery."  The wood stork was ...

On November 26, 2012, the National Marine Fisheries Service (NMFS or the Service) accepted a petition to delist a distinct population segment (DPS) of the Southern Resident killer whales, which is currently listed as endangered under the Endangered Species Act (ESA). 

The DPS, estimated to include 88 individuals, was initially listed as endangered under the ESA in 2005.  These killer whales are "resident" type, fish-eating whales that spend a specific period of time each year in the San Juan Islands and Puget Sound. 

On August 2, 2012, the Service received a petition from the ...
