The two primary plant species in this area are chamise and laurel sumac, with yucca (our Lord's candle), and mission manzanita, with scrub oaks and coyote brush in the ravines. So it seems to fit the sparse waist to chest-high chamise chaparral habitat type tending toward the thicker southern mixed chaparral in the wetter ravine bottoms.
I took the 1/2 mile long and unlabeled Chaparral Nature Trail starting at Jack Creek Picnic Area of Dixon Lake Park and found the typical chaparral species--California Towhee, Wrentit, California Thrasher, Bewick's Wren, Spotted Towhee, House Wren, Rufous-crowned Sparrow, California Gnatcatcher. I was also looking for wintering Fox Sparrows. There are three forms possible: Sooty, Thick-billed, and Slate-colored. I don't have any photos of the local Thick-billed Fox Sparrows (stephensi?). I heard a half dozen Fox Sparrows, but didn't get good looks until I saw a Slate-colored form at the Jack's Creek picnic area--the most common, based on my relatively few personal winter sightings.
