Conservationists released the 10,000th California red-legged frog into Yosemite National Park after a decade-long effort. - The species had vanished from the park due to invasive bullfrogs and raccoons.
- A partnership raised frogs from eggs in a controlled facility in San Francisco. - The population is now successfully breeding in Yosemite Valley.
The milestone reflects years of focused work to restore a species that plays an important role in the park's ecosystem.
