Protected Lands

Land for
Nature + Wildlife

7,000 acres of conserved habitat for
threatened and endangered species.

Ag + Open Space conserves wildlands and watersheds that offer vital habitats for local wildlife to thrive, while also providing our community with clean air, fresh water, and so much more.

A Naturally Wild Landscape

Sonoma County is home to a variety of habitats and ecosystems that make it one of the most biologically diverse areas of the world. The county’s unique natural landscapes include miles of undeveloped coastline, densely forested mountains, oak woodlands, chaparral, rolling grasslands, tidal marshes, freshwater lakes, streams, and vernal pools.

Protecting Vital Ecosystems

Our diverse landscape provides crucial habitats for unique plant and wildlife species while offering essential benefits to our communities. These natural areas filter and recharge our water, protect against floods, aid in crop pollination, and contribute to disaster resilience and climate adaptation.
