Name: Pinus contorta var. latifolia / Purshia tridentata / Festuca idahoensis Woodland
Reference: Western Ecology Working Group of...
Description: This association thrives along the eastern flanks of the Cascade Range of central Oregon. Occurrences are supported by generally low-gradient slopes at elevations between 1280-1740 m (4200-5700 feet). Soils are loamy coarse sand to sandy loams over pumice. Pinus contorta var. latifolia dominates the overstory at 35-60% cover and is considered climax. A component of Pinus ponderosa may exist as understory in higher elevation stands. Purshia tridentata is the sole dominating shrub (0-25% cover) except where a shallow water table occurs. Associated shrubs may include Ribes cereum var. cereum, and Arctostaphylos uva-ursi. The herb layer is typified by Festuca idahoensis (5-30% cover) with lesser amounts of Carex rossii, Achnatherum occidentale (= Stipa occidentalis), Elymus elymoides (= Sitanion hystrix), Penstemon cinicola, and Lupinus caudatus. Fire maintains Pinus contorta var. latifolia forests in this area.
