A common shrub of California chaparral below 5,000 ft, Coast Ranges and western Sierra Nevada, from Shasta Co south to the San Pedro Mártir in Baja California. Type from near Monterey, CA. Chamise chaparral recognized in MCV2 when >50% relative cover. Kern Co.: Infrequent, colonies of only a few plants were reported as scarce in chaparral and Douglas oak woodland, from Caliente and Buck Canyons south to the east slope of the extreme southwestern Tehachapi Mountains (Twisselmann); additionally, however, Adenostoma fasciculatum Alliance recognized on the Tejon Ranch Conservancy (Bicentennial) and may include other species in mixed shrubland species alliances (Ceanothus vestitus, Quercus john-tuckeri, Rhamnus ilicifolia) on White Wolf and Michener sections (Magney 2010). Otherwise, rarity of this species in Kern County suggests that its flora has been dominated by woodland vegetation infiltrated by species from the Mohave Desert and from the Sierra Nevada. Thicket was called a “chamisal among Spanish Californians.
