San Bruno Mountain is a 3,600-acre island of biodiversity surrounded by a sea of urbanization. The mountain is home to 13 rare and endangered plant species and multiple federally listed endangered butterflies. Colorful grasslands, thick woodland canyons, trickling creeks, and scrubby hills grace the mountain's fascinating terrain.  

San Bruno Mountain Watch is a nonprofit, tax-exempt organization under Section 501(c)(3) of the U.S. Internal Revenue Code. Our tax identification number 94-3235791. Meet our board of directors and staff.

The mission of San Bruno Mountain Watch is to care for San Bruno Mountain through conservation, ecological restoration, education, and advocacy in partnership with local communities.

San Bruno Mountain Watch emerged from the web of lively grassroots movements dedicated to protecting San Bruno Mountain. One of our Founders is David Schooley, an artist and environmental activist. David grew up and went to college in Berkeley. In the late Sixties, he discovered San Bruno Mountain while passing by on a Greyhound bus. Concerned by plans to build on the mountain, David joined with local residents to stop the destruction of this unique place. The ensuing multi-decade battle resulted in much of the mountain being preserved as public parkland. Explore our San Bruno Mountain Archives to learn more.

Our grassroots organization is closely tied to the surrounding community. Our organization leads community-based ecological restoration programs that protect and care for the mountain's diverse habitats and we provide environmental education opportunities for people of all ages. Our Mission Blue Nursery provides thousands of plants for restoration efforts on the mountain as well as sustainable landscaping projects in local cities. We work to preserve open space through conservation advocacy and partnerships with landowners and government officials from the surrounding cities and San Mateo County.
