SAVING THE mountain yellow-legged frog
The mountain yellow-legged frog was once the most abundant amphibian in the Sierra Nevada and Transverse Ranges of Southern California. Only a few decades ago, it was difficult to walk around many of California’s alpine lakes without tripping over these diminutive “mountain gnomes.” Today the hardy survivors of freezing, high-elevation winters are vulnerable to a host of modern threats, which have driven the frogs extinct in more than 93 percent of their old mountain homes.
The Center is working to gain full federal Endangered Species Act protection for Sierra Nevada mountain yellow-legged frogs — and meanwhile, thanks to our work, the California Fish and Game Commission designated all populations of the mountain yellow-legged frog as a candidate species, the first step toward a state listing as endangered or threatened.
Southern California mountain yellow-legged frogs have been protected under the Endangered Species Act for about a decade, but the Service has yet to develop a recovery plan to guide their management. To speed recovery of the frogs and other imperiled California amphibians without recovery plans, the Center launched a lawsuit to force the Service to develop the legally required plans.
