Service Seeks Public Comment on Proposed Endangered Species Act Protections for Foothill Yellow-Legged Frog
Media Contacts

The U.S. Fish and Wildlife Service is proposing Endangered Species Act (ESA) protections for four geographically and genetically distinct population segments (DPS) of the foothill yellow-legged frog.

The foothill yellow-legged frog, named for its yellow belly and underside of its rear legs, is found from the Willamette Valley in Oregon to the Santa Lucia mountain range in southern California and from the Pacific coast to the western slopes of the Cascade and Sierra Nevada mountains. The amphibian faces several threats, including altered waterflows related to water infrastructure; competition with and predation by non-native species; disease; precipitation and temperature changes related to climate change climate change
Climate change includes both global warming driven by human-induced emissions of greenhouse gases and the resulting large-scale shifts in weather patterns. Though there have been previous periods of climatic change, since the mid-20th century humans have had an unprecedented impact on Earth's climate system and caused change on a global scale.

“We closely examined the condition of each DPS and the threats they face. Using the best available science, we determined which populations warranted protections under the ESA and where future recovery efforts should be focused,” said Michael Fris, field supervisor of the Service’s Sacramento Fish and Wildlife Office.

To assess the condition of each DPS, the Service evaluated data collected on the frog’s occupancy of streams in its historical range. The Service is proposing to list the South Coast DPS and South Sierra DPS as endangered due to a strong pattern of declining stream occupancy, as well as rapid reductions in occupied range. The North Feather DPS and Central Coast DPS are proposed to be listed as threatened due to decreasing levels of stream occupancy and the potential for a variety of threats to cause additional declines. The North Coast DPS and North Sierra DPS are not warranted for listing after the data showed high levels of occupancy in streams located throughout their ranges, making them more resilient to environmental changes and catastrophic events.

“Our goal is to help the foothill yellow-legged frog recover across its range,” said Fris. “Ongoing collaboration with a number of partners will result in positive conservation gains and put this frog on the road to recovery.”

The Service is working closely with partners at the Oakland Zoo, U.S. Forest Service, Garcia and Associates, Pacific Gas and Electric and California Department of Fish and Wildlife to raise foothill yellow-legged frogs in captivity and release them into Plumas National Forest. The first group of captive-reared frogs, 115 in total, was released in July 2020. A second group of 36 was released in April 2021.

A copy of the finding will publish in the Federal Register on December 28, 2021. The Service plans to develop and propose critical habitat at a later date. The public can submit comments on the proposed listing and read supporting information at www.regulations.gov by searching Docket Number FWS–R8–ES–2021–0108. Comments should be submitted by February 28, 2022.
