It’s home to rare species such as the northernmost stand of desert olive, rare Hospital Canyon larkspur, and threatened Alameda whipsnake, the nonprofit said. Deer, coyotes, burrowing owls, kestrels and lots of other wildlife live on the preserve, too.
The preserve’s high ridgeline provides views of most of central Contra Costa County and even farther to Marin, Sonoma and Solano counties.
