Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Buckbrush Shrubland

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This chaparral shrubland is found in the Klamath Mountains and the central and southern coastal mountains of California. It occurs on moderately steep to steep slopes on most aspects. Sites can be on very rocky serpentine soils in northern California, or on sand to sandy loams derived from fanglomerate, granite, and rhyolite. Shrub cover is moderate to continuous, with Ceanothus cuneatus being the sole dominant shrub. Other shrubs present include Adenostoma fasciculatum in central California, and Ericameria ophitidis on serpentine sites in northern California, each with sparse cover.

Diagnostic Characteristics: No Data Available

Rationale for Nominal Species or Physiognomic Features: No Data Available

Classification Comments: There are various associations in California where Ceanothus cuneatus dominates the shrub layer while the understory is characterized by herbs on various parent materials (differentiated in some associations by serpentine versus non-serpentine substrates).
