A historic cultural attraction and restored lake in San Francisco will serve as a release site for Western pond turtles, which have been the focus of a 6 year collaboration between Sonoma State University and two major zoological parks in the Bay Area—the Oakland Zoo and the San Francisco Zoo. The turtles will be fit with transmitters to aid in telemetry studies for the purposes of tracking and monitoring individual turtles. The data will contribute to larger demographic studies on the turtles.
The significance of this latest release effort is the location of Mountain Lake, a restored ‘living laboratory’ in metropolitan San Francisco. The green space south of the Presidio campus, which is home to the city’s historic military installation, may be one of the finest examples of restored wilderness inside any metropolitan area in the nation.
According to Jessie Bushell, San Francisco Zoo Director of Conservation and Western pond turtle Species Survival Plan (SSP) Coordinator, “The Western pond turtle’s presence is a strong indicator of our ecosystem’s health.”
I first reported on this headstart program for National Geographic in 2012 when 44 juvenile turtles were released at a local site (See Article). The turtles were collected as eggs or hatchlings and reared in captivity until they were large enough to elude predators the size of small mouth bass and American bullfrogs. “The hope is to establish a resident population as the top predators in the lake’s food chain,” said Dr. Geist the lead researcher from Sonoma State University. “It’s up to us to try to bring them back. I can’t save all the turtles, but I can help with this species in our own back yard.”
Margaret Rousser, Zoological Manager at Oakland Zoo said, “The restoration of the lake is such an important project and we are thrilled that the lake will once again have our native Western pond turtles living in it.”
