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.

CONSERVATION

Our goal is to conserve all land on and near San Bruno Mountain as natural open space. We work with local landowners, donors, and government officials to ensure the protection of areas that are eligible for development.
