SAN BRUNO MOUNTAIN WATCH
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! The invasives are a constant battle so we need all the weed warriors we can get! Only heavy rain would cancel - so come prepared. Friday and Saturday 9am to noon.
Join us for a guided hike through Buckeye Canyon, followed by our first planting day of the season! Help plant native vegetation that will feed and shelter the endangered Mission Blue and Callippe Silverspot butterflies.
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!
