Just a mile south of San Francisco, San Bruno Mountain is one of the largest public open spaces in urban America. Our programs conserve and nurture the mountain's unique ecosystems - 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 – and get some exercise! The non-native 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 the Dune Defenders for a guided hike through the Daly CIty Dunes on the west end of San Bruno Mountain, followed by weed removal activities to benefit the endangered San Francisco Lessingia plant!
