Lawsuit Filed to Protect Endangered Sierra Nevada Red Fox Habitat
The Center for Biological Diversity has filed a federal lawsuit against the U.S. Fish and Wildlife Service (FWS) for failing to designate critical habitat protections for the endangered Sierra Nevada red fox.
The complaint, filed in Sacramento, challenges the 2021 decision by FWS that it was “not prudent” to assign critical habitat for the species, which the center claims violates the Endangered Species Act (ESA).
Critical habitat designation is considered a powerful tool for species recovery, doubling the likelihood of long-term improvement. The center argues that denying the Sierra Nevada red fox this protection significantly reduces its chances of survival.
The Sierra Nevada red fox is one of North America’s rarest mammals, uniquely adapted to high-elevation, snowy environments. Historically found throughout the Sierra Nevada and Southern Cascade Ranges, the fox’s population has dwindled to an estimated 18-39 individuals. In 2010, a fox was observed near Sonora Pass, sparking surveys that confirmed a small, isolated population in the region.
Despite listing the species as endangered in 2021, FWS declined to designate critical habitat, citing a “not prudent” determination. This decision was enabled by a 2019 rule change that expanded exceptions to critical habitat requirements. The center contends that the fox faces significant habitat threats from climate change, recreation, development, and livestock grazing, making habitat protection essential.
The lawsuit seeks to compel FWS to provide critical habitat for the species, which the center says is crucial to addressing threats and guiding recovery efforts.
