Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Pacific Poison-oak - Coastal Sagebrush / Giant Wildrye Shrubland
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This shrubland association occurs on somewhat steep to steep northwest- and northeast-facing slopes at low elevations between 0 and 719 m. It is characterized by a strong dominance of Toxicodendron diversilobum and a presence of Artemisia californica in the shrub layer. The herbaceous layer is characterized by relatively high cover of Leymus condensatus. The emergent tree layer may include Juglans californica and Quercus agrifolia.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is likely to be found in other areas along the central and southern coast of California. The mixed evergreen and winter-deciduous classification at the formation group level of the hierarchy is debatable, as many stands of this and other associations in this alliance are strongly dominated by the winter-deciduous Toxicodendron diversilobum.
