Name: Pinus ponderosa / Arctostaphylos patula - Ceanothus velutinus Woodland
Reference: Western Ecology Working Group of...
Description: This is a Ponderosa pine woodland known from interior valleys in southwestern Oregon and northwestern California. This association consists of a physiognomic mosaic of patches dominated by evergreen shrubs and, alternatively, grasses. It primarily occurs on southern and southwestern aspects between 3400 and 5600 feet elevation. Pinus ponderosa is the only dominant tree, but individuals of Pseudotsuga menziesii or Abies grandis can occasionally be found. Arctostaphylos patula and Ceanothus velutinus are the dominant shrubs, although Chrysolepis chrysophylla (= Castanopsis chrysophylla) (which can be a tall shrub or a tree) may gain importance on western and southwestern exposures. Important grasses include Carex inops, Bromus orcuttianus, Festuca idahoensis and Elymus elymoides. Pteridium aquilinum is one of many forbs or ferns which are found in this community.
