Meet the Sierra Nevada yellow-legged frog (SNYLF)! As its name suggests, this small frog is native to the Sierra Nevada. Unfortunately, this species has seen population declines due to the widespread introduction of non-native trout, fungal disease and habitat loss. SNYLF are currently listed as federally endangered and state threatened. To help this species recover, the California Department of Fish and Wildlife (CDFW), U.S. Forest Service-Tahoe National Forest (TNF), U.S. Fish and Wildlife Service and San Francisco Zoo and Gardens (SF Zoo) have partnered on a multi-year project to reintroduce the frog to its native habitat within the western side of the Tahoe National Forest. …To prepare the area for reintroduction of SNYLF to the area, CDFW removed the small population of remaining introduced trout [that ate all the frogs] from 2020 to 2022. to prepare for a reintroduction of SNYLF.
