Endangered Species Law & Policy

On April 19, 2018, the California Fish and Game Commission voted 4-0 to list the tricolored blackbird (Agelaius tricolor) as a threatened species. A statewide survey conducted in 2017 estimated the California population of the species to be over 175,000 birds. The species is broadly distributed in California, occurring in roughly 40 counties, though the bulk of the population resides in the Central Valley.

The Center for Biological Diversity petitioned for the emergency listing of the species in 2015, based on a dramatic decline in population estimates from 2008 to 2011 and again ...

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 11, 2018, Arizona Governor Doug Ducey signed into law H.B. 2238, which amended the state’s administrative procedure laws to provide that courts are not required to defer to an agency’s legal interpretation in lawsuits over administrative decisions. The amendment effectively eliminated Chevron deference, which requires courts to defer to an agency’s reasonable interpretation of an ambiguous statute.

The legal doctrine—named for the 1984 Supreme Court decision in Chevron U.S.A. Inc. v. Natural Resource Defense Counsel, Inc., 467 U.S. 837, 842-844 ...

On April 2, 2018, the U.S. Court of Appeals for the Ninth Circuit affirmed (pdf) a district court order directing that the National Marine Fisheries Service (NMFS), U.S. Army Corps of Engineers (Corps) and U.S. Bureau of Reclamation (Bureau) (collectively, the Federal Agencies) conduct spill operations and fish monitoring at dams and related facilities in the Federal Columbia River Power System (FCRPS).  The appeal was the latest development in a long-running dispute regarding salmon and steelhead species listed under the Endangered Species Act (ESA) that are impacted by FCRPS ...

On April 3, 2018, the U.S. Fish and Wildlife Service (Service) published a final to rule listing the yellow lance mussel (Elliptio lanceolata) as threatened under the Endangered Species Act (ESA).  The final rule states that only seven populations of this freshwater mussel remain, all of which are located in Maryland, Virginia, and North Carolina.  The listing was prompted by a mega-petition filed by the Center for Biological Diversity and several other environmental organizations in 2010 that included the mussel.  In September 2015, after litigation had been filed regarding the ...

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 March 16, 2018, the U.S. Fish & Wildlife Service (FWS) announced the withdrawal of its 2016 proposed rule to list San Fernando Valley spineflower (Chorizanthe parryi var. fernandina), a southern California plant species, as a threatened species under the Endangered Species Act (ESA).  The spineflower’s conservation has been one component of the long-standing conflict over the development of Newhall Ranch in northern Los Angeles County, since its discovery on the property in 2000.

According to FWS, the spineflower no longer meets the statutory definition of a threatened or ...

On February 27, 2018, the National Marine Fisheries Service (Service) published a 90-day finding on the Karuk Tribe and Salmon River Restoration Council’s (Petitioners) petition to list the Upper Klamath-Trinity Rivers Basin (UKTR) Chinook salmon (Oncorhynchus tshawtscha) evolutionarily significant unit (ESU) as endangered or threatened.  Based on the information included in Petitioners’ filing, the Service found that listing the UKTR ESU as endangered or threatened under the Endangered Species Act (ESA) may be warranted.

The Service’s determination follows a ...

In Friends of the River v. National Marine Fisheries Service, the U.S. District Court for the Eastern District of California rejected challenges to Army Corps of Engineers and National Marine Fisheries Service decisions regarding the impact of dams, hydropower facilities, and water diversions along the Yuba River on listed fish species, the spring-run Chinook salmon (Oncorhynchus tshawytscha), the Central Valley steelhead (Oncorhynchus mykiss), and the North American green sturgeon (Acipenser medirostris).  In so doing, the court addressed a number of issues that may arise ...

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 ...
