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.
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.
Our "Dune Defenders" stewardship program will be back at the dunes this Saturday tackling invasives - the target will be Crown daisy before it sets seed in this sensitive area. Sometimes known as Chop-suey Greens - young leaves and petals are edible!
David Schooley, founder of San Bruno Mountain Watch, will lead hikes into Owl and Buckeye Canyons on the 4th Saturday of each month. Be sure to sign up early - space is limited!
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 - you'll join a great group of dedicated volunteers and there's always room for more!
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!
