Common (Translated Scientific) Name: Pacific Poison-oak - Orange Bush-monkeyflower Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association, currently described from southern California, occurs on steep to very steep northeast- and northwest-facing slopes at low elevations between 125 and 591 m. It is characterized by a codominance of Toxicodendron diversilobum and Diplacus aurantiacus in the shrub layer. There are no characteristic species in the herbaceous layer. The emergent tree layer includes Quercus agrifolia in about half the stands.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Both Toxicodendron diversilobum and Diplacus aurantiacus are widespread shrubs in coastal California ranging well north and south of the study area. It is likely that this association occurs farther north into the outer central Coast Ranges (e.g., Big Sur, Monterey County).
