Endangered frog restoration in Yosemite NP passes milestone: over 1000 animals released into park

The California red-legged frog might be nearly extinct, but two of the unsuspecting amphibians ended up making a difference for their dying species.

On Wednesday, the San Francisco Zoo took to Twitter to announce that, earlier this week, the pair of monumental frogs were the 1,000th – and 1,001st – to be released back into their natural habitat of Yosemite National Park.
