About the East Bay Stewardship Network
The East Bay Stewardship Network (EBSN) is a coalition of agencies and organizations caring for over 250,000 acres of interconnected land in the East Bay area.
The San Francisco Bay Area is an internationally recognized biodiversity hotspot with a high density of diverse and unique species. EBSN reflects the connectivity and richness of the East Bay by approaching environmental stewardship at a landscape scale across multiple partners, jurisdictions, and ecologies.
Network by the Numbers
250,000 acres in the Network, roughly 25% of Alameda and Contra Costa Counties, habitat for over 200 threatened and endangered species and 24 plant communities.
15 Core Members and Collaborators, including the Alameda County Resource Conservation District, California State Parks, Contra Costa County Resource Conservation District, East Bay Municipal Utility District, East Bay Regional Park District, East Contra Costa Habitat Conservancy, John Muir Land Trust, Livermore Area Recreation and Park District, National Park Service, Regional Parks Foundation, San Francisco Public Utilities Commission, Save Mount Diablo, UC Berkeley Blue Oak Ranch Reserve, and Zone 7 Water Agency.
EBSN Goals
By working together at a landscape scale across the East Bay we can more successfully:
- Improve the ecological health of East Bay lands.
- Increase climate adaptability to heat, drought, and fires.
- Build broad support for landscape stewardship.
- Align stewardship strategies across landscapes and projects.
- Raise funds and increase investment across boundaries for the benefit of landscape-scale stewardship.
Where We Work
The EBSN’s core area of focus falls primarily within the boundaries of Contra Costa and Alameda counties. It also includes adjacent partner lands that reflect the unique ecological and cultural character and/or watershed boundaries of the East Bay within Santa Clara County and San Joaquin. It extends to bay shoreline and intertidal areas that are a part of current partners’ lands.
