Coastal sage scrub is generally found on dry, rocky slopes of mountains and hillside below 3,000 feet in elevation. On the Etiwanda Fan, coastal sage scrub is found on the lower slopes. The Coastal Sage Scrub climate is characterized by annual rainfall of 10-20 inches primarily falling during the winter, hot dry summers, and an 8-12 month growing season with 230-350 frost-free days. Coastal Sage Scrub vegetation is less dense than chaparral and grows to 1-5 feet tall. Coastal Sage Scrub is a drought-adapted community. Coastal Sage Scrub communities have fewer fire-adapted plants than Chaparral and may take longer to recover after a fire. Indicator species include California Sagebrush (Artemisia californica), White sage (Salvia apiana), Black Sage (Salvia mellifera), California Buckwheat (Eriogonum fasciculatum), Lemonadeberry (Rhus integrifolia), and California Brittlebush (Encelia californica).
