Endangered Species Law & Policy

This week, the United States Fish and Wildlife Service ("Service") published a final rule designating critical habitat for the northern Mexican gartersnake (Thamnophis eques megalops) under the Endangered Species Act (“ESA”).  The final critical habitat designation includes a total of approximately 20,326 acres of land located in Arizona and New Mexico. 

The northern Mexican gartersnake, an olive-colored snake identifiable by a pattern of vertical yellow stripes and paired black dots lining its body, typically occurs in shallow wetlands and aquatic habitats, such ...

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 ...

The Sacramento Superior Court upheld a challenge to a decision by the California Fish and Game Commission to designate four subspecies of bumble bees as candidates for protection under the California Endangered Species Act (CESA). The decision in Almond Alliance et al. v. California Fish and Game Commission reinforces a long line of authority dating back several decades suggesting that insects are not subject to protection under CESA. It also reflects respect for the role of the coordinate branches of government in formulating, executing and interpreting the laws that the ...

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 ...

The United States Fish and Wildlife Service ("Service") has recently received an application for an incidental take permit under Endangered Species Act section 10(a)(l)(A) to authorize take of the West Coast distinct population segment ("DPS") of fisher (Pekania pennanti) ("fisher") should it or its subpopulations become federally listed. As we have previously reported, the Service recently listed the Southern Sierra Nevada DPS of fisher as an endangered species.

The permit application, submitted by Oregon-based timberland investment company Chinook Forest Partners ...

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 ...

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 ...
