A dense chaparral to 3m tall, clearly dominated by Ceanothus cuneatus with some admixture of Adenostoma fasciculatum. Cover is higher than in Chamise Chaparral (37200) but is not so dense because the branches are not so interwoven.
SITE FACTORS:
Dry slopes and alluvial fans, usually below 6,000 feet. This may be a climax chaparral in parts of its range, but it clearly is seral to some deciduous oak woodlands (71110-71140) or Lower Montane Coniferous Forests (84000) at many sites.
DISTRIBUTION:
Widely distributed from southwestern Oregon to northern Baja California, especially in the north where it appears to replace Chamise Chaparral (37200).
