Name: Pinus ponderosa / Arctostaphylos patula - Purshia tridentata Woodland
Reference: Western Ecology Working Group of...
Description: This forest association is common in the eastern Cascades of Oregon and California. It is found at elevations between 915 and 1980 m (3000-6500 feet) on all aspects of variable steepness. Soils are derived from basalt, ash, and cinders but vary in water-holding capacity. The overstory is typically a semi-open canopy (5-48% cover) of <i>Pinus ponderosa</i>. Other trees may occur but are always subdominant and include <i>Abies concolor</i> and <i>Pinus contorta</i>. The shrub layer is codominated by <i>Arctostaphylos patula, Purshia tridentata</i>, and <i>Ceanothus velutinus</i> with occasional <i>Ericameria bloomeri</i>. The herb layer usually supports at least one grass species, such as <i>Festuca idahoensis, Achnatherum occidentale ssp. occidentale (= Stipa occidentalis)</i>, and <i>Elymus elymoides ssp. elymoides (= Sitanion hystrix)</i>. Many different forbs can be found, although none have high cover. In natural condition, this community is associated with periodic non-stand-replacing fire.
