Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This coniferous forest of the Siskiyou Mountains typically grows on south- to southeast-facing slopes between 850 and 1650 m of elevation. Winters are mild and wet, but summers are subject to long periods of heat and drought. The open overstory canopy is dominated by Pinus ponderosa with minor amounts of Pseudotsuga menziesii, Quercus garryana, Quercus kelloggii, and Arbutus menziesii. At least one species of Arctostaphylos is present, usually Arctostaphylos patula and/or Arctostaphylos viscida.

Classification Comments: Arctostaphylos viscida is used to differentiate stands of this type from a slightly cooler and moister type, ~Pinus ponderosa - Pseudotsuga menziesii / Arctostaphylos patula Woodland (CEGL000209)$$. Arctostaphylos viscida may not occur within the stand but will be present in the adjacent vegetation matrix.
