Endangered Species Law & Policy

Today, the United States Court of Appeals for the Ninth Circuit issued a decision (pdf) relating to the 2008 biological opinion (BiOp) issued by the U.S. Fish and Wildlife Service (Service) regarding the effects of the Central Valley Project and State Water Project on the delta smelt. The long-awaited decision (oral argument was held on September 10, 2012) reversed in part and affirmed in part the district court’s judgment invalidating the BiOp and remanding it to the Service. The opinion is authored by Judge Bybee, with partial concurrence and partial dissent by both Judge ...

In an article forthcoming in the Journal of Environmental Studies and Sciences, Dr. Dennis Murphy and I examine a proposal by the Fish and Wildlife Service and National Marine Fisheries Service to amend the existing regulations that implement the interagency consultation process set out in Section 7 of the Endangered Species Act by codifying their pre-existing practice of using surrogates to express the amount or extent of incidental take of listed species.  We describe the proposed rule, place the use of surrogates for conservation planning in historical context, and ...

The U.S. Fish and Wildlife Service (Service) has announced the availability of a revised recovery plan for the pallid sturgeon (Scaphirhynchus albus), a species that is found in the Missouri and Mississippi River basins, has been described as having a "unique dinosaur-like appearance," and has been listed as endangered since 1990.  As summarized by the Service, the revised recovery plan updates the "current understanding of the species life history requirements, identifies probable threats that were not originally recognized, includes revised recovery ...

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 ...

The U.S. Fish and Wildlife Service (Service) issued a final rule (pdf) listing the Georgetown salamander (Eurycea naufragia) and the Salado salamander (Eureycea chisholmensis) as threatened under the Endangered Species Act (ESA). The Service also issued a proposed special rule for the Georgetown salamander under section 4(d) of the ESA, which authorizes the take of protected species in certain instances.

The primary threat to the species is habitat degradation due to declining water quality and disturbance of surface spring sites. According to the Service, urban development ...

In an article (pdf) forthcoming in the Journal of Environmental Studies and Sciences, Dennis Murphy and I explore the potential for adaptive management through structured decision-making to improve efforts to conserve imperiled species.  We note the many impediments to effective management, which include frequent default to best professional judgment.  We then explore the potential for adaptive management to overcome these impediments if it is implemented as a step-wise, structured approach incorporating scientific information into decision-making.  We go on to identify  ...

Today, the National Marine Fisheries Service (NMFS) announced (pdf) a 90-day finding on a petition to list the Hector’s dolphin (Cephalorhynchus hectori), the Baltic Sea subpopulation of harbor porpoise (Phocoena phocoena), the eastern Taiwan Strait subpopulation of the Indo-Pacific humpback dolphin (Sousa chinensis), and the Fiordland subpopulation of the bottlenose dolphin (Tursiops truncatus) under the Endangered Species Act. The announcement came as a result of NMFS' determination that the petition presented substantial scientific and commercial information ...

The U.S. Fish and Wildlife Service has announced a final rule listing the Georgetown salamander (Eurycea naufragia) and Salado salamander (Eureycea chisholmensis) as threatened species under the Endangered Species Act.  The final rule is scheduled to be published in the Federal Register on Monday.  According to an article by Claire Osborn of the Austin American-Statesman, "Williamson County officials have said the area would lose millions of dollars in development if the salamanders are listed."

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 ...
