Local Conservation Efforts

The care of wildlife extends far beyond the Zoo’s gates. Learn more about our leading roles in conserving western pond turtles and Sierra Nevada yellow-legged frogs.


Western Pond Turtle (WPT) Project

A partnership between the San Francisco Zoo, the Oakland Zoo, and Sonoma State University. Project goals are to determine the critical temperature and timing of sex determination in WPT to optimize male-female sex ratios for ex-situ incubation and to establish a WPT head starting program at San Francisco and Oakland Zoos. These goals are essential to the immediate conservation and ultimate recovery of the turtle.

Sierra Nevada Yellow-Legged Frogs

Through this project, begun in 2010, the Conservation and Education Committee has allocated funding for equipment, resources, and internships. The San Francisco Zoo was recently awarded a grant by the AZA for Testing the Effectiveness of Head Starting as Part of a Conservation Toolbox to Restore the Sierra Nevada Yellow-Legged Frogs (Rana sierrae) to the Lake Tahoe Basin.

Pacific Chorus Frog Project

The project aims to restore this native frog to the wetlands around the Zoo. Over 600 tadpoles were raised and released in 2007 and in 2008 twenty additional ‘froglets’ were released at the Zoo. In 2009 additional tadpoles and egg masses were released into Zoo wetland ponds. You can hear our chorus frogs throughout the Zoo.
