U.S. Fish and Wildlife Service Proposes Endangered Species Act Protections for Sierra Nevada Amphibians
On April 25, 2013, the U.S. Fish and Wildlife Service (Service) published a proposed rule (pdf) to list the Sierra Nevada yellow-legged frog (Rana sierrae) as endangered, the northern distinct population segment (DPS) of the mountain yellow-legged frog (Rana muscosa) as endangered, and the Yosemite toad (Anaxyrus canorus) as threatened under the Endangered Species Act (ESA).
According to the Service, populations of the Sierra Nevada yellow-legged frog and the northern DPS of the mountain yellow-legged frog are declining due to habitat degradation and fragmentation, predation, disease, climate change, and other factors impacting the species’ vitality. The Service also determined that Yosemite toad populations are likely to decrease due to habitat degradation and anticipated effects of climate change.
In addition to the proposed listing, the Service also published a proposed rule (pdf) to designate critical habitat for the three species. Specifically, the Service proposed designating over 1.1 million acres of critical habitat for the Sierra Nevada yellow-legged frog, over 200,000 acres for the northern DPS of the mountain yellow-legged frog, and over 750,000 acres for the Yosemite toad. The critical habitat designations include acreage in seventeen counties across California, ranging from Tulare County in the south to Butte County in the north.
Comments regarding either proposed rule must be submitted by June 10, 2013.

In conjunction with its proposed listing, the Service also proposed designating 293 stream miles of critical habitat for the species in Arizona and New Mexico and on Navajo Nation land. According to the Service, the species' habitat has been lost or degraded due to water withdrawal, logging, overgrazing, development, and erosion.
endangered under the California Endangered Species Act. Currently, the take and possession of white sharks is protected from sport and commercial fishing activities, with limited exceptions, under existing laws. However, the scientific information in the petition demonstrates that the species may benefit from additional regulation. If the petition is accepted by the California Fish and Game Commission (Commission) for consideration, the Commission will initiate a year-long scientific-based review of the species to determine whether or not listing is warranted..jpg)
