Dense 2-5m tall chaparrals dominated by any of several species of manzanita. May occur as a post-fire successional stage in burned Westside Ponderosa Pine Forest (84210), Sierran Mixed Conifer Forest (84230), White Fir Forest (84240, 85320), or Jeffrey Pine Forest (85100). Plants dormant during winter, most active in late spring and early summer.
SITE FACTORS:
Similar to and often intergrading with Upper Sonoran Mixed Chaparrals (37100), but generally at higher elevations and therefore cooler and moister. Often immediately below or on rockier more xeric sites than Westside Ponderosa Pine Forest (84210).
DISTRIBUTION:
Scattered in Klamath and North Coast Ranges south to Lake County. Common in the western foothills of the Cascade-Sierra south to Yuba and Nevada counties (2,000-4,000 feet), scattered from there south in the Sierra to Kern County (3,000-5,500 feet) and the higher mountains of southern California.
