Fortunately, many parks in the Bay Area, including those of the East Bay Regional Parks, offer welcome refuge for a variety of oak woodlands.

In the 40 years since the movement to save San Francisco Bay began, we have moved from desperately fending off more bay fill projects to proactively restoring thousands of acres of shoreline wetlands.
