San Francisco Airport Protects Endangered Species Until it Boasts More of Them Than Any Place on Earth

The garter snake that inhabits the San Francisco peninsula has human protectors who have given it a safe haven near the runways of the San Francisco International Airport.

The snake is mostly isolated around the San Francisco peninsula, they are thriving in numbers near the tarmac of the airport known as SFO.

A tract of 160 privately-owned acres has been put to work to save the beautiful reptile, including the construction of many small ponds where the snake can keep moist, breed, and hunt for its favorite prey: the red-legged frog—which is also endangered and given sanctuary on the SFO runway lawn.
