Just a mile south of San Francisco, San Bruno Mountain is one of the largest open spaces in urban America. Our programs conserve and nurture this area’s unique ecosystem - home to 13 rare and endangered plants and three federally listed endangered butterflies.
Help us restore this magical wetland that is a breeding ground for the Pacific Chorus Frog and other native species - including a spectacular array of California native plants.
Join us this Wednesday - we'll be working rain or shine with activities determined by the weather - getting ready for another big Spring plant sale on May 14th.
Explore San Bruno Mountain's less-traveled canyons and learn about their history and ecology on this docent-lead hike. Paul's hikes are one of our most popular events!
Take part in the exciting start to San Bruno Mountain Watch's "Dune Defenders" stewardship program! You'll start the afternoon with a guided educational hike through the sandy dunes before helping remove invasive ice plant to make room for specialized native dune plants to expand.
Our upcoming native plant sale will focus on helping you create a pollinator's paradise in your garden, especially for native bees. Become Bee Dazzled! We have what you need to make your garden a pollinator's paradise. Mary Beth, nursery volunteer and avid native gardener, will give a presentation on native bees - learn how to attract bees as well as other important pollinators.
Join the SSF Weed Warriors for their restoration work on the Mountain's south slope – come one day or both! There should still be wildflowers to enjoy as the display progresses through the season. Only heavy rain would cancel - so come prepared. Friday and Saturday 9am to noon.
