"USGS ecologists helped release a batch of young Mountain Yellow-Legged Frogs (Rana muscosa) into a California nature reserve on Thursday, June 12, 2013.

The froglets were bred at the San Diego Zoo Institute for Conservation Research, and will help restore wild populations of this highly endangered species, which has only about 200 adults remaining in the wilds of Southern California.

USGS ecologists lead the field monitoring and ecological research effort for this species on behalf of the U.S. Fish and Wildlife Service. Read more about this news at: http://www.fws.gov/cno/press/release.cfm?rid=501.”
