Dense, 1-3m tall mostly sclerophyllous chaparral dominated by any of several species of ceanothus. Plants winter-dormant, most active in late spring and early summer. These stands are taller (to 10 feet) and much denser than other Montane Chaparrals. At least three types are recognized based on the dormant species: 37531-Deer Brush Chaparral (C. intergerimus); 37532-Whitethorn Chaparral (C. leucodermis); and 37533 Tobacco Brush Chaparral (C. velutinus).
SITE FACTORS:
Similar to and often intergrading with Upper Sonoran Mixed Chaparral (37100), but generally higher (therefore cooler and moister). Most stands are successional after fire, landslide, gold mining, or other catastrophic disturbances. Best developed on dry, exposed sites.
DISTRIBUTION:
Scattered widely in the lower elevation conifer zones (5,000-8,000 feet) throughout California.
