According to USGS, the release is part of a broader effort to rebuild populations in the San Gabriel Mountains, where the species has faced wildfire, drought, disease, non-native predators, and habitat loss.
How the recovery effort works
USGS said scientists and zoo partners rear tadpoles and froglets in captivity before releasing them into carefully selected habitat. After release, USGS researchers study how the frogs survive, grow, and reproduce in the wild, the agency said.
USGS said that follow-up research helps scientists understand what it takes to establish healthy, self-sustaining populations.
More than 1,000 frogs have been reared and released, USGS says
With this summer's release, USGS said more than 1,000 mountain yellow-legged frogs have now been reared and released into the San Gabriel Mountains as part of the conservation effort.
The agency said the work involves scientists, zoos, and federal and state partners working together to help the endangered species recover.
