California red-legged frog marks comeback in Yosemite

Conservationists released the 10,000th California red-legged frog into Yosemite National Park on May 7, 2026, after a decade-long recovery effort. The species had vanished from the park due to invasive bullfrogs and raccoons.

- The 10,000th frog was named "Twain" after Mark Twain's story. - The frogs are raised from eggs in a controlled facility in San Francisco.

- The population is now successfully breeding in Yosemite Valley. - The species is California's official state amphibian and a threatened species.

This milestone highlights the success of a partnership between multiple agencies and the resilience of the species despite environmental challenges.
