The San Francisco Police Department is launching extra patrols along the fence line of open space at SFO to protect the endangered San Francisco Garter Snake and the threatened Red-Legged Frog.
The species are no strangers to most Pacificans, as they live on the and are at the center of a legal battle between environmental groups and golfers that threatens the future of golf there.
According to the Huffington Post, the airport has had issues with trespassers on the property, which includes wetlands, that borders San Francisco's Bayview District.
"We've always had fences along the property," SFO spokesman Mike McCarron told The Huffington Post. "But nearby residents kept jumping them or cutting holes in them to get inside."
SFO sits on 32 acres of filled-in wetlands, and the airport has made improvements to 558 acres of neighboring wetlands and tidal marshes to compensate for airport activities. Those efforts have included planting trees, building canals and using goats rather than machines for vegetation management.
