San Francisco still has extraordinary diversity of native plant and animal communities, including grasslands, wetlands, coastal scrub, dunes, oak woodlands, and, of course, the Estuary and the Pacific Ocean.


Explore and Restore: people and organized groups participate in community-based stewardship of our local natural lands, restoring habitat and their own nature connection, thereby nurturing local ecological health as well as their own.


The Biodiversity program collaborates with partners on nature conservation strategies and policies. We facilitate sustainable restoration and stewardship of our wild lands and wildlife habitats, and educate the public about our living natural heritage and local ecological stewardship opportunities.
