The San Francisco Garter Snake is amazingly beautiful and also very endangered, but now with the help of the conservation program at the San Francisco Zoo, they may get a chance at re-establishing their population! The largest current population of the snake lives on the property of the San Francisco airport and is quite protected but there is another area in Pacifica that conservationist from the Zoo have been preparing to help headstart a population of 115 babies for a spring release with more planned for the future!

Those destined for Pacifica will be released into a habitat that has been upgraded for their arrival. The project included creating a new pond for snakes and red-legged frogs to thrive, and removing invasive Monterey Cypress and Monterey Pine trees.
“If we didn’t do any type of tree removal, those scrub and grassland areas would be converted into forested habitats,” said Fong. “For sun-loving reptiles like snakes, converting open grasslands and scrub to forested habitats is not great.”
In December, a vegetation crew from NPS scattered seeds to help populate the upgraded habitat with native plant species.
One remaining concern is the continuing threat posed by people and their pets. The striking colors that make the San Francisco garter snake a California icon have also made it a target for illegal poaching for the pet trade, said McNellis. SFO can secure its habitat with a security fence, but other habitats cannot provide protection.

The work that went into this project is amazing and hopefully provides for a successful recovery for these gorgeous snakes! To read the full article, please visit The Mercury News here. This project was extensive and impressive! Kudos to the San Francisco Zoo for their work!
