Endangered Species Law & Policy

As we have previously reported, on December 6, the Biden Administration released the Fall 2023 Unified Agenda of Regulatory and Deregulatory Actions (Unified Agenda), which lists the regulatory and deregulatory actions that federal administrative agencies—including the U.S. Fish and Wildlife Service (Service)—plan to take in the coming year. According to the Unified Agenda, the western United States can expect a number of proposed and final rules to list species as threatened or endangered under the Endangered Species Act (ESA) and to designate critical habitat ...

On November 7, 2022, the U.S. Fish and Wildlife Service (Service) proposed to designate approximately 595,495 acres of critical habitat for the Southern Sierra Nevada distinct population segment (DPS) of fisher (Pekania pennanti) under the Endangered Species Act (ESA). The critical habitat designation would span six units in California’s Tuolumne, Mariposa, Madera, Fresno, and Tulare Counties. The majority of the land comprising these units is owned and/or managed by federal, state, or tribal governments.

The fisher is a small, carnivorous mammal native to North American ...

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 Thursday, October 5, 2017, the U.S. Fish & Wildlife Service (Service) announced 12-month not warranted findings on petitions to list 25 species as endangered or threatened under the Endangered Species Act (ESA).  It is likely that the Service’s not warranted findings represent the Trump administration’s departure from the previous administration’s  90-day determinations wherein the Service found that the petitions contain substantial information that listing may be warranted.  For over half of the 25 species, the not warranted findings satisfy the terms of various ...

On August 6, 2015, the California Fish and Game Commission (Commission) voted to list the southern Sierra Nevada evolutionarily significant unit of the fisher (Pekania pennati) as a threatened species under the California Endangered Species Act, but determined not to list the northern California evolutionarily significant unit.  In doing so, the Commission followed the recommendation of the California Department of Fish and Wildlife (Department).

According to the Department’s status review, [n]ative populations of fishers currently occur in Canada, the western United ...

On October 6, the U.S. Fish and Wildlife Service (Service) issued a news release (pdf) announcing its proposal to list the West Coast Distinct Population Segment (West Coast DPS) of fisher (Pekanian pennanti) as threatened under the Federal Endangered Species Act (ESA), in part due to significant threats from illegal marijuana farming. 

The fisher belongs to a family of mammals that includes weasels and otters, and grows to about the size of a large house cat.  The Federal Register notice (pdf) regarding the proposed listing, which was published yesterday, states that the ...
