Native, threatened Western pond turtles were released into San Francisco's Mountain Lake Saturday afternoon in the culmination of a seven-year-long species restoration effort by Sonoma State University biologists and the Oakland and San Francisco Zoos.
Western Pond Turtle project biologists released 24 turtles into the newly-renovated Inner Richmond District park at 3 p.m. following a Science Saturday talk at the Mountain Lake Outdoor Classroom on the northern end of the lake.
The turtles released will be sporting special transmitters for further research as they settle into their new home, zoo officials said.
According to Oakland Zoo officials, Mountain Lake was selected as the turtles' habitat because it has undergone recent restoration and is now deemed suitable for the species to populate.
"This is a great opportunity to take this project and relocate these turtles to a restored environment," Sonoma State Professor of Biology Nick Geist said in a statement.
These Western pond turtles were hatched two to three years ago and raised at the Oakland and San Francisco zoos to be given a good head start, according to Oakland Zoo officials.
San Francisco zoo officials held an event on July 30 to discuss how the public can work with the zoo to help restore Western pond turtles in the Bay Area.
The baby turtles were raised at the zoos to ensure that they grew to healthy sizes, an advantage zoo officials believe will set them up to be able to fend off predators such as bullfrogs and largemouth bass, and help them compete against red-eared sliders, a non-native, more aggressive turtle species.
"The hope is to establish a resident population as the top predators in the lake's food chain," Sonoma State Professor of Biology Nick Geist said in a statement. "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 backyard."
According to Geist, Western pond turtles are the only native freshwater aquatic turtle in all of California, and they are a threatened species. The Western Pond Turtle project was born when Geist realized there was a lack of information on these turtles and decided to rectify this.
"The Western pond turtle's presence is a strong indicator of our ecosystem's health," Western Pond Turtle Species Survival Plan Coordinator Jessie Bushell said in a statement. "Through our conservation efforts, we hope children will experience the joy of seeing a Western pond turtle in the wild 20 years from now."
As indicated by Saturday's release, this day could be much sooner.
