Major habitat restoration moves ahead for two endangered montane frogs in California. After years of review and planning, the National Park Service (USA) is officially moving forward with major plans to restore high elevation aquatic ecosystems in the Sequoia and Kings Canyon National Parks in the Sierra Nevada of California. These actions will help recover two endangered montane frogs, the Sierra Nevada yellow-legged frog (Rana sierrae) and the Sierra Madre or Southern Mountain yellow-legged frog (Rana muscosa). These significant conservation actions, based in part on results from a 2004 field experiment (Vredenburg 2004) showing rapid recovery of endangered frogs after removal of introduced non-native fish (trout) from habitats, will help the frogs as they face new threats such as disease, drought and climate change.
