Endangered Species Law & Policy

On April 28, 2016, the U.S. Fish and Wildlife Service (USFWS) issued a revised Biological Opinion and Incidental Take Permit for the Rosemont Copper Mine in Pima County, Arizona. USFWS originally issued a Biological Opinion and Incidental Take Permit for the mine project in 2013. Consultation with USFWS was reinitiated in 2015 primarily due to the listing of additional species not considered during the initial consultation.

The Rosemont Copper Mine is proposed on approximately 955 acres of private land and 75 acres of Arizona State Land Department land, on the east side of the ...

On April 21, 2016, the U.S. Fish and Wildlife Service and National Marine Fisheries Service (collectively, Service) announced revisions to their proposed modifications  to  the Endangered Species Act (ESA) petition process. 81 Fed. Reg. 23,448 (Apr. 21, 2016) (pdf).  In May 2015, the Service announced proposed changes to the petition process for listing a species or seeking to change the listing status of a species under the ESA. 80 Fed. Reg. 29,286 (May 21, 2015) (pdf).  The Service’s proposed rule originally required petitions to list species to address only one species, contain ...

Environmental Management has released an advanced copy of an article I co-authored with Dr. Dennis Murphy entitled, Guidance on the Use of Best Available Science under the U.S. Endangered Species Act.  The principle purposes of the article are to identify the types of data, analyses, and modeling efforts that can serve as best available science and consider the role and application of best available science in effects analysis and adaptive management.  The article is available free of charge, here

This week, two congressional committees are holding three separate hearings on issues related to the Endangered Species Act (ESA).  On April 19, the House Committee on Natural Resources will hold an oversight hearing entitled Recent Changes to Endangered Species Critical Habitat Designation and Implementation.  On April 20 and 21, the House Oversight and Government Reform Subcommittee on Interior will hold two hearings to discuss delisting under the ESA.  Nossaman partner, Robert D. Thornton, will testify at the committee hearing on April 20.

The hearing before the Natural ...

On April 8, the United States District Court for the Middle District of Florida held that Collier County’s (County) land use planning regulations were complimentary, not contrary to the Endangered Species Act (ESA).  The court also held that the County's planned future roadway extension did not violate the ESA, because the roadway project was only in the initial planning stages and the County acknowledged that compliance with the ESA was required before any construction activities could take place. Florida Panthers v. Collier County, Case No. 2:13-cv-612 (M.D. Fla. Apr. 8 ...

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 April 5, 2016, the U.S. Fish and Wildlife Service (Service) issued 12-month findings on petitions to list the island marble butterfly (Euchloe ausonides insulanus), the San Bernardino flying squirrel (Glaucomys sabrinus californicus), the spotless crake (Porzana tabuensis), and the Sprague’s pipit (Anthus spragueii) under the Endangered Species Act.  The Service concluded that the listing of the island marble butterfly is warranted but precluded by higher priority listing actions, but will place the butterfly on the list of candidate species.  The Service also concluded ...

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 March 8, 2016, the U.S. Fish and Wildlife Service (Service) announced (pdf) proposed revisions to its Mitigation Policy that has guided Service recommendations on mitigating the adverse impacts of development on fish, wildlife, plants, and their habitats since 1981.  The revised policy provides a framework for achieving a net gain in conservation outcomes, or at a minimum, no net loss of resources and their values, services, and functions resulting from proposed actions.

The Mitigation Policy serves as over-arching guidance applicable to all actions for which the Service has ...

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 February 5, 2016, the U.S. Fish and Wildlife Service and National Marine Fisheries Service (collectively, the Services) announced the availability of two final rules and one policy addressing critical habitat under the Endangered Species Act (ESA).  One of the final rules  revises the definition of destruction or adverse modification, an issue that has been controversial among both critics and proponents of the proposed revisions.  The other final rule  is intended to clarify the criteria for designating critical habitat.  The final policy  updates existing policy on critical ...

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 ...

In a notice published on January 15, 2016, the U.S. Fish and Wildlife Service (Service) announced a draft methodology for prioritizing species status reviews and 12-month findings on petitions for listing species under the Endangered Species Act (ESA).  81 Fed. Reg. 2,229 (Jan. 15, 2016).  The Service currently has over 500 unresolved species status reviews and associated 12-month findings on petitions for listing, and intends to use the changes to its methods to set priorities on how and when those unresolved petitions will be addressed.  The Service’s draft methodology will not ...

On January 6, 2016, the U.S. Fish and Wildlife Service (Service) issued its 12-month finding on the petition to list the Alexander Archipelago wolf (Canis lupus ligoni) as an endangered or threatened species under the Endangered Species Act, concluding that listing the wolf species throughout all or a significant portion of its range "is not warranted at this time."

The Alexander Archipelago wolf inhabits the mainland of southeastern Alaska, coastal British Columbia, and several island complexes.  On March 31, 2014, the Service issued a 90-day finding for the wolf stating that ...

Under the Endangered Species Act (ESA), a citizen plaintiff is required to provide a notice no less than 60-days before filing certain types of lawsuits against the federal government.  For example, a 60-day notice is required before a citizen plaintiff may file a lawsuit seeking to compel the U.S. Fish and Wildlife Service (Service) to issue a decision on an ESA listing petition.  The primary purpose of the 60-day notice is to give the federal government an opportunity to review and, if necessary, correct the alleged ESA violation before incurring the cost of ...

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 ...

In 2012, the U.S. Fish and Wildlife Service (Service) published a final rule designating 1,724 acres as critical habitat for the endangered Riverside fairy shrimp (Streptocephalus woottoni).  Included in that designation were 56 acres of private land, on which the plaintiff, Otay Mesa Property, L.P. (Otay Mesa), had planned to build a recycling facility and landfill.  Because of the land use restrictions potentially implicated by the critical habitat designation, Otay Mesa challenged the final rule in federal court, asserting that (1) the Service improperly ...

On November 16, 2015, the U.S. Fish and Wildlife Service (Service) issued a final rule (pdf) removing the Delmarva fox squirrel (Sciurus niger cinereus) from the list of endangered and threatened species.  Following its 2012 review of the species, the Service concluded that the best available scientific and commercial data indicate the Delmarva fox squirrel is no longer in danger of extinction or likely to become endangered within the foreseeable future.

The Service credits the Delmarva fox squirrel’s recovery primarily to the establishment of new populations of the species ...

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 ...

In a notice published on October 8, 2015, the U.S. Fish and Wildlife Service (Service) announced its proposed 12-month finding on the Center for Biological Diversity’s (CBD) petition to list the Sierra Nevada red fox (Vulpes vulpes necator) as endangered or threatened under the federal Endangered Species Act. The Service determined that listing of the subspecies is not warranted because the fox is more abundant than previously believed and because known and potential stressors to the fox are not likely to cause the subspecies to become endangered in the foreseeable future ...

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 18, 2015, the U.S. Fish and Wildlife Service (Service) issued 90-day findings on 25 petitions to list various plants and animals under the Endangered Species Act (ESA).  Of the 25 petitions, the Service concluded that 23 petitions presented substantial scientific or commercial information indicating that the petitioned actions may be warranted, and initiated 12-month status reviews for those species to determine if the listing is warranted under the ESA.  These species include:

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 September 15, 2015, the U.S. Fish and Wildlife Service (Service) published (pdf) its 12-month finding on a petition to list the New England cottontail (Sylvilagus transitionalis) as an endangered or threatened species under the Endangered Species Act (ESA).  The Service determined that listing the species is not warranted.

The New England cottontail is the only rabbit native to New England and the area east of the Hudson River in New York.  It was first identified as a candidate species in 2006, when the Service published a finding that listing the New England cottontail as ...

Under the Migratory Bird Treaty Act (MBTA), it is unlawful to "pursue, hunt, take, capture, kill, attempt to take, capture, or kill . . . any migratory bird" protected by the Act.  16 U.S.C. 703(a) & 704(a).  In a recent decision, the U.S. Court of Appeals for the Fifth Circuit found that although the MBTA imposes a strict liability standard for any of the aforementioned acts, in order for an unlawful "taking" to occur, the defendant must have taken a "deliberate act done directly and intentionally to migratory birds."  United States v. CITGO Petroleum Corp., No. 14-40128 (5th Cir. Sept. 4 ...

On September 1, the U.S. District Court for the Western District of Texas, Midland Division vacated the U.S. Fish and Wildlife Service’s (Service) Final Rule listing the Lesser Prairie Chicken (LPC) as threatened.  The Service had published its final rule listing the LPC as threatened on April 10, 2014 amidst significant controversy as to whether the listing was needed.  In conjunction with the decision to list the LPC as a threatened species, the Service issued a special take rule under section 4(d) of the Endangered Species Act.  The 4(d) Rule allowed those who participate in the ...

On August 25, 2015, the U.S. Fish and Wildlife Service (Service) published a proposed rule relating to the existing critical habitat for the marbled murrelet (Brachyramphus marmoratus).  The murrelet is listed as a threatened species under the Endangered Species Act (ESA).  The proposed rule does not purport to change the Service’s previous designation of critical habitat for the murrelet in 1996, as amended in 2011.  61 Fed. Reg. 26,256; 76 Fed. Reg. 61,599.

The Service is reconsidering its prior critical habitat determination pursuant to the U.S. District Court for the District ...

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 ...

Whether dealing with water or with endangered species directly, there have been a number of recent developments that are worth keeping on your radar.  Below is a quick summary of some of the more significant items:

July 16, 2015 - The House of Representative, in a largely partisan vote, passed H.R. 2898, the Western Water and American Food Security Act of 2015, by a vote of  245-176.  The Act, which is intended to ease some of the effects of the unprecedented drought gripping California, requires, among other things, for the U.S. Fish and Wildlife Service, the National ...

On July 6, 2015, the U.S. Fish & Wildlife Service (Service) published a Draft Polar Bear (Ursus maritimus) Conservation Management Plan (Polar Bear Plan).  The Polar Bear Plan identifies the continuing loss of sea-ice habitat as the single greatest threat to the species’ continued survival, and the global reduction of greenhouse gases (GHG) as the most important action to halt and reverse this trend.  The Polar Bear Plan also addresses several high priority actions designed to maintain the polar bear population, including reducing risks from spills, protecting ...

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.

On June 18, 2015, the U.S. District Court for the Eastern District of California denied a motion for a temporary restraining order and preliminary injunction, finding the plaintiff failed to establish that an emergency salinity barrier would imminently harm species listed under the Endangered Species Act (ESA).  Center for Environmental Science, Accuracy & Reliability (CESAR) v. Cowin, No. 1:15-cv-00884-LJO-BAM (E.D. Cal Jun. 18, 2015) (pdf).

CESAR filed an action against the California Department of Water Resources (DWR) and the U.S. Fish and Wildlife Service (Service) on ...

On May 27, 2015, the U.S. Court of Appeals for the Ninth Circuit provided some additional guidance as to what constitutes agency action for purposes of triggering the consultation requirement under the Endangered Species Act (ESA).  The court held that although the U.S. Bureau of Land Management (BLM) was required to consult with the U.S. Fish and Wildlife Service (FWS) on the effects of a proposed road project on BLM land, BLM was not required to consult on the effects of a proposed wind project that would be accessed via the federal road project.  Sierra Club v. BLM, Case No. 13-15383 ...

On Tuesday, May 26, 2015, the U.S. Court of Appeals for the District of Columbia Circuit rejected (pdf) the National Association of Home Builders’ and three other associations’ (collectively, NAHB) challenge to separate settlements between the U.S. Fish and Wildlife Service (Service) and two environmental organizations. The settlements direct the Service to make listing decisions on 251 species by specified dates.  The Court of Appeals affirmed a district court’s decision that NAHB lacked standing to raise its challenge.

As we previously reported, the district court ...

While a number of Endangered Species Act (ESA) reform bills continue to wind their way through Congress (see our May 6, 2015 post), yesterday, the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) announced their own plan to "increase regulatory predictability, increase stakeholder engagement, and improve science and transparency" when acting on petitions to list, uplist, downlist, or delist a species, as well as petitions to revise critical habitat designations.  Rather than revising the ESA itself, as some in Congress ...

On April 27, 2015, the Chairman of the House Armed Services Committee, released the text (pdf) of the National Defense Authorization Act (Act), including language that would ban the U.S. Fish and Wildlife Service (Service) from issuing its listing decision for the greater sage-grouse (Centrocercus urophasianus) under the Endangered Species Act (ESA) through September 30, 2025.  The Act would also limit the application of federal conservation plans for the species.

As we previously reported, the greater sage-grouse is a candidate species under the ESA.  In 2010, the Service ...

While the larger controversy is far from over, for the California and Nevada populations of the greater sage grouse (Centrocercus urophasianus), the controversy does appear to be put to rest.  In 2013, the U.S. Fish and Wildlife Service (Service) published a proposed rule to list the bi-state population as threatened under the Endangered Species Act (ESA).  In the proposed rule, the Service stated that the bi-state population was genetically distinct and geographically isolated from other greater sage grouse populations, and warranted protection under the ESA primarily because ...

On Tuesday, April 14, 2015, the U.S. Fish and Wildlife Service (Service) reopened the public comment period on its proposed rule (pdf) designating critical habitat for the Zuni bluehead sucker (Catostomus discobolus), a fish species that lives in certain water bodies in New Mexico. In January 2013, the Service proposed to designate 291.3 miles of critical habitat for the species. Due to information received during the public comment period, the Service now proposes to reduce the amount of critical habitat designated for the species to 141.9 miles, of which approximately 70% is ...

On April 3, 2015, a federal district court in California put the brakes on a proposed logging project, invalidating a habitat conservation plan and incidental take permit issued by the U.S. Fish and Wildlife Service (FWS) and National Marine Fisheries Service (NMFS) under section 10 of the Endangered Species Act (ESA), as well as a biological opinion and incidental take statement issued by NMFS under section 7. Klamath-Siskiyou Wildlands Ctr. v. Nat’l Oceanic and Atmospheric Administration, Case No. 13-cv-03717 (N.D. Cal. Apr. 3, 2015) (pdf).

A project can avoid the general take ...

On April 2, 2015, the U.S. Fish and Wildlife Service (Service) issued a final rule (pdf) listing the northern long-eared bat (Myotis septentrionalis) as threatened under the Endangered Species Act (ESA).  The Service determined that there are several factors affecting the species, but none as severe and immediate to its persistence as the disease known as white-nose syndrome (WNS).  The Service found that WNS is the predominant threat to the northern long-eared bat and, in the absence of WNS, the species would not be experiencing the dramatic decline that it has since WNS emerged.

The ...

After a relatively quiet start to the year, the National Marine Fisheries Service (NMFS) and U.S. Fish & Wildlife Service (FWS)  have issued findings and rules regarding the proposed listings of four separate species under the Endangered Species Act (ESA) over the last two days.  NMFS issued a 90-day finding on a petition to list the Gulf of Mexico population of Bryde's whale (Balaenoptera edeni) on April 6, 2015.  FWS issued a 12-month finding on a petition to list the Humboldt marten (Martes caurina humboldtensis) and proposed to list two species of crayfish - the Big Sandy crayfish ...

In a three-page memorandum decision, the United States Court of Appeals for the Ninth Circuit dismissed Wild Equity and other groups' appeal from a lower court decision, dismissing as moot a lawsuit alleging that the City and County of San Francisco ("San Francisco") violated the Endangered Species Act’s take prohibition as a consequence of its continuing operations of the Sharp Park Golf Course. (2015 U.S. App. LEXIS 4854 [pdf].)

The lower court dismissed the action on the grounds that the Fish and Wildlife Service issued a biological opinion and incidental take statement ...

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 ...

On Friday, February 20, a federal district court denied (pdf) a motion to dismiss, thereby breathing life into an Endangered Species Act (ESA) challenge brought against the Export-Import Bank of the United States (Bank) for funding activities in and around Australia’s Great Barrier Reef World Heritage Area. See Center for Biological Diversity, et al. v. Export-Import Bank of the United States, No. C 12-6325 SBA (N.D. Cal. Feb. 20, 2015). As previously reported on this blog, the case alleges that the Bank violated section 7 of the ESA by failing to consult with federal wildlife ...

Last week, the U.S. Fish and Wildlife Service (Service) published three new rules, continuing its flurry of activity from December as we previously noted here and here.  Below are the latest final and proposed rules issued by the Service.

January 16, 2015 – The Service issued a final rule listing the Mexican wolf (Canis lupus baileyi) (pdf) as endangered under the Endangered Species Act (ESA).  The Mexican wolf is a subspecies of the gray wolf that was listed as endangered in the southwestern United States and Mexico in April of 1976.  When the gray wolf was listed as endangered in 1978, it ...

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 ...

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 ...

The United States District Court for the District of Columbia recently held (pdf) that the U.S. Fish and Wildlife Service (Service) violated the Endangered Species Act (ESA) when it issued a final rule delisting gray wolves in nine states (Final Rule) because the Service’s interpretation of the ESA, particularly its identification of a Distinct Population Segment (DPS) to support delisting, was unreasonable.  Humane Society of the United States v. Jewell, Case No. 13-186 (D.D.C. Dec. 19, 2014).

The Final Rule, which took effect in January 2012, is the Service’s fourth ...
