Overview

“Can we save the best Pacific chorus frog habitat in the urban Bay Area?” asks Jim McKissock, a longtime Bay Area conservationist and founder of EarthCare, a group of activists that has restored habitat for the frogs in Brisbane. “These frogs’ calls once epitomized the sound of the Bay Area.” 

At the base of the eastern side of San Bruno Mountain, hundreds of them live in an aquifer-fed ditch among cattails, willows, tule, native herbaceous plants, gopher and garter snakes, swallowtail butterflies, hummingbirds, and numerous small mammals. 

The Crocker Park Recreational Trail, a 2.5-mile loop, runs alongside the re-stored frog habitat. It’s a great place to stop to listen to the frogs and see the work of volunteers who have cleaned out trash, pulled weeds, and generally fixed the place up. You can walk through the abandoned Bayshore railroad tunnel due east of the frog habitat; farther out is an old brick icehouse. 

There’s a proposal to build a candy factory where an old warehouse sits now. That would probably be the end of the frogs. But for now, the effort to preserve the frogs’ habitat continues with a volunteer work party every Tuesday from 10 a.m. to 1 p.m. (info: earthcarenow@sbcglobal.net).

Getting there: North on 101, exit Bayshore Boulevard toward Cow Palace. Go left at Valley Drive; right on Cypress to 100 Cypress Lane. South on 101, exit Cow Palace/Third Street and take Bayshore Boulevard 1.8 miles. Right on Valley Drive and right on Cypress Lane. [Jessica Hahn-Taylor]
