1,000th California Red-Legged Frog Released at Yosemite

On Monday, the 1,000th California red-legged frog raised at the San Francisco Zoo was released into Yosemite National Park as part of a program aimed at reintroducing the nearly-extinct amphibian into areas where it has not been seen for 50 years.

For three years, the California red-legged frog has been at the center of a multi-agency effort to reintroduce the nearly-extinct amphibian into Yosemite National Park.

Yosemite National Park saw the California red-legged frog vanish in large part because of the introduction of the non-native bullfrog.

The milestone release came after three years of collaboration between several agencies including the San Francisco Zoological Society, who raised the frogs from eggs and tadpoles, and the National Park Service. Other agencies that were part of the effort were Yosemite Conservancy, U.S. Fish and Wildlife Service and the California Department of Fish and Wildlife.
