After Decades Away, Western Pond Turtles Come Home to Mountain Lake
By Lauren McNulty, Bay Nature
It had been a long time since Mountain Lake was the kind of place where a western pond turtle could live happily. For decades, the Presidio’s natural freshwater lake suffered environmental insults: runoff from Highway 1, sediment pollution, invasive species, voracious released goldfish. Mountain Lake had been “a cesspool since the ’70s and ’80s,” says Jonathan Young, a wildlife ecologist with the Presidio Trust. “It was a soupy, green, algae-scummy sort of lake.”
Not anymore. On Saturday, a few dozen people sat on a grassy slope overlooking the green, reflective surface of the almost completely restored lake, and waited for one of the final pieces: the return of the native turtles.
