Endangered Species Law & Policy

On August 10, 2023, the U.S. Fish and Wildlife Service (Service) issued a proposed rule to designate critical habitat for the Sacramento Mountains checkerspot butterfly (Euphydryas Anicia cloudcrofti) under the Endangered Species Act. The proposed critical habitat designation encompasses 1,636.9 acres of land in the Sacramento Mountains in Otero County, New Mexico, and follows the Service’s January 2023 final rule listing the species as endangered.

As explained in the proposed rule, the Service considered physical and biological features “essential to the ...

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 June 29, 2021, fourteen members of Congress delivered a letter to Secretary of the Interior Deb Haaland urging the U.S. Fish and Wildlife Service (Service) to use its authority to list the monarch butterfly (Danaus plexippus) on an emergency basis under section 4 of the Endangered Species Act (ESA). The letter, which garnered only Democratic support, notes that the population of western monarchs has sunk to under 2,000 individuals and states that immediate action is necessary to prevent extinction of the species.

Section 4 of the ESA authorizes the Service to immediately place a ...

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 ...

On May 14, 2021, the Department of Justice filed a brief with the Supreme Court arguing that the Court should not hear the case of Kansas Natural Resource Coalition v. Department of Interior (“KNRC”). KNRC is a challenge to a rule interpreting the Endangered Species Act (“ESA”) that was jointly issued by the United States Fish and Wildlife Service (“USFWS”) and the National Marine Fisheries Service (“NMFS”) (collectively, the “Services”) in 2003: The “Policy for Evaluation of Conservation Efforts When Making Listing Decisions,”(68 Fed. Reg. 15,100 ...

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 ...

The U.S. Fish and Wildlife Service (USFWS) has announced the next chapter in the lesser prairie chicken’s (Tympanuchus pallidicinctus) (LEPC) tumultuous listing history. On May 26, 2021 the USFWS announced that it will propose a rule to establish a Northern distinct population segment (DPS) and a Southern DPS of the LEPC.  USFWS has proposed to list the Southern DPS – consisting of portions of New Mexico and Texas – as endangered. If finalized, the ESA take prohibition would apply across the Southern DPS without exception. The USFWS proposes to list the Northern DPS ...

On May 5, 2021, the U.S. Fish and Wildlife Service (“USFWS”) published its updated collision risk model (“CRM”) for bald and golden eagles at wind energy facilities.  The CRM is a complex Bayesian model the USFWS has endorsed to predict eagle fatalities at wind energy facilities seeking eagle incidental take authorization under the Bald and Golden Eagle Protection Act (“BGEPA”).  The USFWS previously published the proposed updates to CRM for public comment on two occasions, seeking input on three alternatives: (1) Use updated species-specific model inputs and use the ...

The U.S. Fish and Wildlife Service (Service) recently announced its finding that three salamander species do not warrant listing as endangered or threatened species under the Endangered Species Act (ESA). The Service’s announcement follows a court-approved settlement agreement in which the Service agreed to make a 12-month finding for the Shasta salamander (Hydromantes shastae), Samwel salamander (H. samweli), and Wintu salamander (H. wintu). The finding comes despite concerns from some environmental groups that a proposed project to raise the height of the Shasta Dam and ...

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 May 7, 2021, the U.S. Fish and Wildlife Service (USFWS), as many anticipated, published a proposed rule to revoke a Trump Administration rule impacting the scope of the Migratory Bird Treaty Act (MBTA).  The Trump Administration rule was finalized on January 7, 2021 and became effective March 8, 2021.  It clarified that the MBTA’s prohibition against the take of migratory birds did not extend to death or injury of migratory birds that results from, but is not the purpose of, an action (also known as incidental take).  Prior to the Trump Administration Rule, USFWS had, for decades ...

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 November 19, 2020, in a call back to its criminal lawsuit against Joseph “Tiger King” Maldonado-Passage, the U.S. Department of Justice filed a civil lawsuit against the husband and wife team who took over the wildlife park that was front and center throughout the Netflix hit series Tiger King – Jeffrey and Lauren Lowe. Unlike the prior lawsuit against Mr. Maldonado-Passage (previously covered here), the lawsuit against the Lowes does not seek jail time, nor does it seek damages. Instead, the lawsuit asks the U.S. District Court for the Eastern District of Oklahoma to (1 ...

The United States Fish and Wildlife Service ("Service") recently released a pre-publication version of its final rule to reclassify the American burying beetle (Nicrophorus americanus) from endangered to threatened under the Endangered Species Act (“ESA”).  The final rule will also include 4(d) rule provisions that specify when the ESA section 9 take prohibitions will apply to the beetle.

The American burying beetle, which gets its name from its tendency to burrow under vegetation or into soil during the daytime and throughout the winter hibernation season, is the largest ...

On August 19, 2020, the U.S. Fish and Wildlife Service (Service) published a proposed rule that would remove the Stephens’ kangaroo rat (Dipodomys stephensi) from the federal list of Endangered Species. The proposed rule would, instead, list the kangaroo rat as threatened under the Endangered Species Act (ESA), and would provide a rule under ESA section 4(d) to provide for conservation of the kangaroo rat.

The Stephens’ kangaroo rat was originally listed as an endangered species in 1988. It is a small, nocturnal mammal, with external cheek pouches, large hind legs, a long tail ...

The California Fish and Game Commission deferred the decision on whether to make the western Joshua tree a candidate for listing to a special meeting in September 2020. In a hearing on August 20, 2020, the Commission heard a wide variety of perspectives on whether listing the species may be warranted. The California Department of Fish and Wildlife’s 90-day evaluation recommended a “may be warranted” finding but at the hearing Director Bonham indicated he was open to deferring the decision in order to work with the stakeholders ... 

On May 15, 2020, the U.S. Fish and Wildlife Service ("Service") published a final rule in the Federal Register announcing the agency’s determination to list the Southern Sierra Nevada (SSN) Distinct Population Segment (DPS) of fisher (Pekania pennanti) as endangered under the Endangered Species Act (ESA).

The fisher is a small, carnivorous mammal in the mustelid (commonly referred to as weasel) family. The SSN DPS of fisher, which occurs in California, was recently determined by the Service to be a separate subpopulation of the West Coast DPS.

The Service first proposed to list ...

Many projects require federal incidental take authority due to impacts on species listed under the federal Endangered Species Act (“ESA”). Depending upon the species, this federal take authority is obtained either from the U.S. Fish and Wildlife Service (“USFWS”) or National Marine Fisheries Service (“NMFS”). These agencies provide take authority either through a Section 7 (federal consultation) incidental take statement or Section 10 (Habitat Conservation Plan) incidental take permit. These authorizations almost always require the permittee to undertake ...

This week, the U.S. Fish and Wildlife Service (USFWS) announced its opening of 5-year status reviews for 25 southeastern species and 10 southwestern species. Among the species included in the status review are the dusky gopher frog (Lithobates sevosus), Jollyville Plateau salamander (Eurycea tonkawae), and many other species of fish, wildlife, and plants. Five-year status reviews are required under section 4(c)(2)(A) of the Endangered Species Act and serve to inform USFWS whether a given species warrants a change in listing status (e.g., de-listing or a change from threatened ...

The U.S. District Court for the District of Montana has approved a partial settlement between the Center for Biological Diversity (CBD) and the U.S. Fish and Wildlife Service (Service) requiring that the Service complete and post a status review of the lower-48 grizzly bear (Ursus arctos horribilis) populations no later than March 31, 2021.  Earlier this year, CBD filed a lawsuit challenging the Service’s alleged failure to update a 1993 federal recovery plan for the species.  The partial settlement disposes of CBD’s first claim for relief, which alleged that the Service had ...

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 27, 2019, the U.S. Fish and Wildlife Service and National Marine Fisheries Service (Services) announced the finalization of regulations governing implementation of various aspects of the Endangered Species Act (ESA). Among those regulations were rules setting forth how the Services and other federal agencies were to consult on potential impacts of federal activities on ESA-listed species and designated critical habitat.  The new rules were to go into effect on September 26, 2019.  Today, the Services announced that the effective date for the interagency consultation ...

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 April 2, 2018, the U.S. Fish and Wildlife Service (Service) proposed downlisting the Hawaiian goose (Branta sandvicensis), locally known as the nene, from endangered to threatened under the Endangered Species Act (ESA).  The Service also proposed adopting a special rule pursuant to ESA section 4(d), known as a section 4(d) rule, allowing incidental take of nene for particular conservation and law enforcement functions.

The nene was federally listed as endangered in 1967, after the population fell below 30 individuals on Hawaii’s Big Island.  The Service instituted a ...

On October 17, 2017, the California Fish and Game Commission (Commission) published notice of its preliminary positive finding on a petition to list the Cascades frog (Rana cascadae) as threatened or endangered under the California Endangered Species Act (CESA).  The Cascades frog inhabits a variety of habitats—including large lakes, ponds, wet meadows and streams—at mid-to-high elevations from the Klamath-Trinity region, along the Cascades Range axis in the vicinity of Mt. Shasta, southward to the headwater tributaries of the Feather River.  The California populations ...

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 May 17, 2017, the U.S. Court of Appeals for the Ninth Circuit affirmed a ruling by the U.S. District Court for the District of Montana and upheld the U.S. Forest Service’s (Forest Service) decision to construct 4.7 miles of new roads in the Kootenai National Forest. The Kootenai National Forest is managed pursuant to the Forest Service’s Kootenai National Forest Plan (Forest Plan) that includes access-related amendments prohibiting any net permanent increase[] in linear miles of total roads.  These Forest Plan access amendments incorporate a 2011 Biological Opinion and ...

On January 11, 2017, the U.S. Fish and Wildlife Service (Service) published a final rule listing the rusty patched bumble bee (Bombus affinis) as endangered under the Endangered Species Act (ESA).  The rusty patched bumble bee’s historic range encompassed areas of 28 states and the District of Columbia (Connecticut, Delaware, Georgia, Illinois, Indiana, Iowa, Kentucky, Maine, Maryland, Massachusetts, Michigan, Minnesota, Missouri, New Hampshire, New Jersey, New York, North Carolina, North Dakota, Ohio, Pennsylvania, Rhode Island, South Carolina, South Dakota ...

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 November 1, 2016 the U.S. Fish and Wildlife Service (Service) announced its plan to issue what will be only the second programmatic eagle take permit under the Bald and Golden Eagle Protection Act (BGEPA) permit program since the program's establishment in 2009.  Programmatic permits may be sought to authorize eagle take that is associated with, but is not the purpose of, an activity if such take is compatible with the preservation of the bald eagle and the golden eagle and if the take is unavoidable even though advanced conservation practices are being implemented.

Alta ...

On August 10, 2016, the U.S. Fish and Wildlife Service (USFWS) issued a proposed rule to list the Texas hornshell (Popenaias popeii), a freshwater mussel, as an endangered species under the Endangered Species Act (ESA).  The species has been on the candidate species list for over a decade, and the proposed rule meets a listing determination deadline established by a 2011 multidistrict settlement agreement.  In the proposed rule, USFWS determined that the species is in danger of extinction due to habitat loss from loss of water flow, decreased water quality, increased accumulation of ...

On June 7, 2016, the U.S. Court of Appeals for the Ninth Circuit rejected plaintiffs’ claim, among others, that the U.S. Bureau of Land Management’s (BLM) violated the Migratory Bird Treaty Act (MBTA) by granting a right-of-way to a private company to develop and operate a wind energy facility.  Protect Our Communities Foundation v. Jewell, No. 14-55842, 14-55666 (9th Cir. June 7, 2016).

Plaintiffs argued that BLM—by granting a right-of-way to Tule Wind LLC (Tule)—was "complicit" in future conduct by Tule that might result in violations of the MBTA.  Beyond this assertion of ...

After filing an appeal with the U.S. Court of Appeals for the Fifth Circuit less than two weeks prior, on May 10, 2016, the U.S. Fish and Wildlife Service (Service) filed an unopposed motion to voluntarily dismiss its appeal of the district court decision that vacated the listing of the lesser prairie-chicken (Tympanuchus pallidicinctus) as threatened under the Endangered Species Act (ESA).  The U.S. District Court for the Western District of Texas, Midland Division, identified a number of errors in the Service’s evaluation of the species under the criteria laid out in the ...

On April 4, 2016, the U.S. District Court for the District of Montana vacated the U.S. Fish and Wildlife Service’s (Service) August 13, 2014 withdrawal of its proposed rule to list the distinct population segment of the North American wolverine (Withdrawal).  The Withdrawal signaled a complete departure from the Service’s February 2013 proposed rule to list the wolverine as a threatened species under the Endangered Species Act (ESA).  The court’s decision is the newest chapter in what has been a contentious and storied path to a listing decision for the North American ...

On March 30, 2016, the U.S. Fish and Wildlife Service ("Service") issued a final rule designating critical habitat for 125 species listed as endangered or threatened under the Endangered Species Act ("ESA") on the Hawaiian islands of Molokai, Maui, and Kahoolawe.  The rule designated critical habitat for 50 plant and animal species, and revised critical habitat for 85 plant species, totaling approximately 157,002 acres of critical habitat on Molokai, Maui, and Kahoolawe.  An additional 25,413 acres of critical habitat that had been proposed on Lanai, along with 59,479 acres on Maui ...

On February 29, 2016, the U.S. District Court for the Western District of Texas rejected the U.S. Fish and Wildlife Service's (Service) request to reinstate federal Endangered Species Act (ESA) protections for the lesser prairie chicken (Tympanuchus pallidicinctus).  Permian Basin Petrol. Ass 'n v. Dep 't of the Interior, No. 7:14-CV-50 (W.D. Tex. Feb. 29, 2016.).  In September 2015, the court ruled on a challenge brought by the Permian Basin Petroleum Association and four New Mexico counties and vacated the final rule listing the lesser prairie chicken as threatened under the ESA.  ...

On February 10, 2016, lawmakers on the House Natural Resources Subcommittee on Water, Power, and Oceans are scheduled to discuss several wildlife laws, including the Endangered Species Act (ESA), Marine Mammal Protection Act (MMPA), and Migratory Bird Treaty Act (MBTA).  The Oversight Hearing is entitled The Costly Impacts of Predation and Conflicting Federal Statutes on Native and Endangered Species.  Anticipated topics for discussion include addressing the fact that conflicts between federal statutes often prevent agencies and federal officials from effectively reducing ...

On December 24, 2015, the U.S. Fish and Wildlife Service (Service) released its annual Candidate Notice of Review (CNOR) summarizing the status of species that qualify as candidates for listing under the Endangered Species Act (ESA).  The 2015 CNOR identifies all species designated as candidates and explains the changes to the candidate list from the 2014 CNOR.  The Service assigns each candidate species a listing priority number (LPN) indicating the magnitude of the threat to a species’ continued existence (with one being the highest priority, and twelve being the lowest ...

On December 3, 2015, the U.S. Court of Appeals for the Ninth Circuit affirmed the U.S. District Court for the District of Oregon’s denial of a preliminary injunction sought by environmental plaintiffs to enjoin the Douglas Fire Complex Recovery Project in Oregon’s Klamath Mountains.  Cascadia Wildlands v. Thrailkill, No. 14-35819 (9th Cir. Dec. 3, 2015).  The environmental groups asserted that the Bureau of Land Management’s (BLM) combined recovery project and logging plan to salvage acreage burned by the Douglas Complex Fire would irreparably harm the threatened ...

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 ...

During the last week of its fiscal year, the U.S. Fish and Wildlife Service (Service) made several findings under section 4 of the Endangered Species Act (ESA) to meet its obligations under the 2011 listing settlement workplan.  Below is a brief summary of these findings.

On September 29, 2015, the Service published a proposed rule to list four plant species from South Florida (specifically Miami-Dade and Monroe counties).  These include the Big Pine partridge pea (Chamaecrista lineata var. keyensis), the wedge spurge (Chamaesyce deltoidea ssp. Serpyllum) the sand flax (Linum ...

On September 22, 2015, Secretary of the Interior Sally Jewell announced that the greater sage-grouse (Centrocercus urophasianus) does not warrant protection under the Endangered Species Act (ESA).  The Department of the Interior is calling the greater sage-grouse strategy the largest land conservation effort in U.S. history and a 21^st-century approach to conservation.  In reaching its not warranted finding, the U.S. Fish and Wildlife Service (Service) relied upon the collective conservation efforts of the Bureau of Land Management (BLM), U.S. Forest Service (USFS), State ...

On September 14, 2015, the U.S. District Court for the Eastern District of California granted the state and federal defendants’ motion to dismiss for lack of subject matter jurisdiction.  Center for Environmental Science, Accuracy & Reliability (CESAR) v. Cowin, No. 1:15-cv-00884 (pdf). Plaintiff CESAR claimed that the construction and operation of an emergency drought salinity barrier (Project) in the Sacramento-San Joaquin River Delta—which is designated as critical habitat for the threatened delta smelt (Hypomesus transpacificus)—violates the section 9 ...

On July 24, 2015, the U.S. Fish and Wildlife Service (Service) published a notice seeking authorization from the Office of Management and Budget to evaluate habitat conservation banks established under the Endangered Species Act (ESA) through a survey of bank sponsors and managers.  80 Fed. Reg. 44,147.  The Service and the Department of the Interior’s Office of Policy Analysis state that they are undertaking this effort to identify potential institutional or other impediments to the habitat conservation banking program, and develop possible options for encouraging expanded ...

On July 1, 2015, the U.S. Fish and Wildlife Service (Service) published notice of its 90-day findings on petitions to list 31 species under the Endangered Species Act (ESA).  Of these 31 species, all of which occur in the United States, the Service made positive 90-day findings on 21 petitions.  A positive finding on a listing petition prompts a 12-month review of each species by the Service to determine whether listing is warranted.  Of the remaining ten petitions, the Service concluded that nine petitions failed to provide substantial information demonstrating that listing action may be warranted.  Most species addressed in the findings originated from a 53-species mega-petition filed by the Center for Biological Diversity (CBD) in July 2012.  If the Service finalizes its May 21, 2015 proposed rule to revise the regulations for species listing petitions, multi-species petitions such as the one filed by CBD will no longer be accepted by the Service.

Perhaps most notably, the Service’s publication included a denial of the petition to reclassify or downlist the gray wolf (Canis lupis) from its current status as endangered to threatened.  Twenty-two petitioners (including the Humane Society of the United States, CBD, and the Sault Sainte Marie Tribe of Chippewa Indians) signed the 2015 petition requesting reclassification of the gray wolf (excluding the Mexican wolf subspecies (Canis lupus baileyi) throughout the conterminous United States).  The Service first concluded that the petition failed to provide substantial information indicating that the population proposed for reclassification may qualify as a distinct population segment.  The Service acknowledged that this finding alone was enough to deny the petition for reclassification, but stated that the status of the gray wolf has been a source of significant controversy over the past few years, and due to the controversy, also concluded that the petition did not provide substantial information indicating that the gray wolf at large would qualify as threatened rather than endangered.

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 ...

Coming in just under the wire for the New Year, the U.S. Fish & Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) published new rules today, making December a very busy month for Endangered Species Act (ESA) listing decisions. Below are the latest items from FWS and NMFS to be published in 2014.

December 31, 2014 - FWS issued a 90-day finding on a petition to list the Monarch Butterfly (Danaus plexippus plexippus) as a threatened species under the ESA.  FWS found that the information and sources cited in the petition present substantial commercial or scientific ...
