Restore Native Frogs and Turtles – 2018

Restore Native Frogs and Turtles – 2018

Biologists are saving California red-legged frogs, Sierra Nevada yellow-legged frogs and Western pond turtles from the brink of extinction in Yosemite

Support from donors in recent years has enabled biologists to work toward restoring populations of native frogs and turtles in Yosemite. In the high country, the endangered Sierra Nevada yellow-legged frog is making gains after a precipitous population decline; in the Valley, successful efforts have brought the western pond turtle and California red-legged frog back after decades of absence.

This year, with your help, scientists will continue to bolster the park’s amphibian and reptile populations, working with the San Francisco Zoo to rear young turtles and red-legged frogs, using new insights to identify ideal release sites in the Valley, and carefully moving yellow-legged frogs to additional high-altitude lakes. Ultimately, these efforts will help all three species continue to regain their footholds in the Sierra Nevada ecosystem.

Your gift will help protect native wildlife and restore ecosystem balance in Yosemite.

Project Notes
Thanks to donor support, 500 red leg frogs have been released in Yosemite.

In one year, we went from inception of an idea to full implementation, collecting over 500 red-legged frog eggs, raising them at a zoo, and releasing them in Yosemite. We are making history.
