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 ...

On June 4, 2021, the Biden administration announced its intent to rescind or revise several implementing regulations for the Endangered Species Act (ESA) finalized under the prior administration. The U.S. Fish and Wildlife Service (Service) has not yet published these proposed rules in the Federal Register, nor has the Service provided the exact dates when it intends to publish the proposed rules.

In its announcement, the Service indicates its intent to rescind regulations governing how the Service conducts critical habitat exclusion analyses under ESA section 4(b)(2) and how ...

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 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 ...

On November 3, 2020, the United States Fish & Wildlife Service (“Service”) published a final rule removing the gray wolf (canis lupus) from the federal list of Endangered and Threatened Species in the lower 48 United States and Mexico. The rule will take effect on January 4, 2021. At the same time, the Service denied a petition, filed by environmental groups, to maintain protections for the gray wolf in the lower 48 United States. However, the Service did maintain the separate listing of the Mexican wolf subspecies as endangered, a listing that was put in place on January 16, 2015; the ...

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.

For the second time in a decade, the U.S. Court of Appeals for the Ninth Circuit has invalidated a decision by the U.S. Fish and Wildlife Service (Service) to remove the Greater Yellowstone grizzly bear (Ursus arctos horribilis) population from the federal endangered species list.  Crow Indian Tribe v. State of Wyoming, Case No. 18-36038 (9th Cir. July 8, 2020).  In 2011, the Ninth Circuit invalidated the decision to delist the Greater Yellowstone grizzly population because the evidence did not support the Service’s conclusion that the decline of white bark pine did not threaten the ...

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 October 24, 2019, the U.S. Fish and Wildlife Service (FWS) published a proposed rule in the Federal Register announcing the agency’s finding that the interior least tern (Sterna antillarum) is no longer warranted for listing as an endangered species under the Endangered Species Act (ESA).

The interior least tern, the smallest of the tern species in North America, was first observed in 1804 by explorers Meriwether Lewis and William Clark. The fish-mongering bird currently nests adjacent to major U.S. rivers within the Lower Mississippi Valley and the Great Plains region across ...

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 ...

More than a year after the U.S. Fish and Wildlife Service (USFWS) and National Marine Fisheries Service (NMFS) (collectively, Services) published proposals to revise several Endangered Species Act (ESA) implementing regulations, the agencies have announced that the final versions of the rules are ready for publication in the Federal Register ...

Over the last few weeks, besides proposing to remove the gray wolf (Canis lupus) from the List of Endangered and Threatened Species (which we covered here), the U.S. Fish and Wildlife Service (Service) has made a few other moves related to the Endangered Species Act (ESA).

On Monday, April 8, 2019, the Service published a final rule, removing one species from the List of Endangered and Threatened Species, adding 16 separate species to the list, and updating the existing entries for 17 more species.  Specifically, the Service added the following species to the ESA List: Gulf grouper ...

On March 28, 2019, a federal judge overturned the U.S. Fish and Wildlife Service’s (USFWS) rejection of a petition to delist an endangered karst invertebrate species, the Bone Cave harvestman (Texella reyeisi) (BCH), which is known to occur only in central Texas.

American Stewards of Liberty and others (Plaintiffs) had claimed that USFWS’ rejection of a 2014 petition to delist the BCH was arbitrary and capricious because, among other things, USFWS based its rejection on the petition’s supposed failure to provide BCH population trend data that was unavailable and is ...

On March 15, 2019, the U.S. Fish and Wildlife Service (Service) issued a proposed rule to remove the gray wolf (Canis lupus) from the List of Endangered and Threatened Wildlife.  As we reported here, the Service announced its intention to issue the proposed rule earlier this month.  According to the Service, the species’ population has rebounded considerably since it was originally listed in 1978, when the population estimate was approximately 1,000 individuals.  Now, the Service estimates there is a Great Lakes meta-population with approximately 4,400 individuals, along with an ...

On February 26, 2018, the U.S. Fish and Wildlife Service issued a proposed rule to delist the Borax Lake chub (Gila boraxobius), a small fish that currently resides primarily in a single Oregon lake.  Currently listed as an endangered species, the proposed rule states that the best available scientific and commercial information "indicates that the threats to the Borax Lake chub have been eliminated or reduced to the point where the species no longer meets the definition of an endangered or threatened species under the Endangered Species Act . . . ."  The Federal Register notice ...

On February 6, 2019, a federal judge upheld U.S. Fish and Wildlife Service’s (Service) 90-day finding that a petition to delist the endangered golden-cheeked warbler (Petition) did not present substantial information that delisting the warbler may be warranted (Negative 90-day Finding). In 2015,  various groups and individuals filed the Petition, which, among other things, alleged that because a 2015 study indicated that the golden-cheeked warbler and its habitat were far more abundant than the Service originally believed at the time of the bird’s listing in 1990, the bird ...

On January 31, 2019, the U.S. Fish and Wildlife Service (USFWS) announced plans to amend up to 182 Endangered Species Act (ESA) recovery plans, which potentially cover over 305 animal and plant species, over the next year. These amendments will revise each recovery plan to include quantitative recovery criteria as part of the Department of the Interior’s Agency Priority Performance Goals. USFWS kicked off this 12-month push by releasing a notice of availability of 26 draft recovery plan amendments ...

The last several days have seen a flurry of activity in the federal courts in matters involving the Endangered Species Act (ESA):

• In Crown Indian Tribe v. United States, CV 17-89-M-DLC, the U.S. District Court for the District of Montana vacated (pdf) a June 30, 2017 final rule issued by the U.S. Fish and Wildlife Service (Service) delisting the Greater Yellowstone Ecosystem population of grizzly bear (Ursus arctos horribilis). The court held that the Service violated the ESA when it delisted the Greater Yellowstone grizzly distinct population segment (DPS) without any analysis of ...

In recent weeks, the Trump Administration and Congress have proposed changes to the Endangered Species Act (ESA) and its implementing regulations. Lawmakers from the Congressional Western Caucus introduced nine bills that would, according to the 15 legislators that introduced the bills, amend and modernize the ESA.  The lawmakers assert that the bills would also incentivize voluntary conservation efforts, let states enter into cooperative agreements for recovery, and prioritize data from local communities in making scientific decisions about conservation.

The bills ...

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 ...

The U.S. Fish and Wildlife Service (FWS) issued a final rule removing the lesser long-nosed bat (Leptonycteris curasoae yerbabuenae) from the Federal List of Endangered and Threatened Wildlife due to recovery.  According to FWS, threats to the bat have been eliminated or reduced and populations are healthy and stable such that the species is no longer endangered or threatened with endangerment under the Endangered Species Act (ESA).  It is the first bat species delisted from the ESA due to recovery.

When the bat was first listed in 1988, fewer than 1,000 bats at only 14 known roosts were ...

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 ...

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.
