Name: Pinus contorta / Purshia tridentata / Festuca idahoensis Woodland
Reference: NatureServe Biotics 2019
Description: This association thrives along the eastern flanks of the Cascade Range of central Oregon. <i>Pinus contorta var. latifolia</i> dominates the overstory and is considered climax. A component of <i>Pinus ponderosa</i> may exist as understory in higher elevation stands. <i>Purshia tridentata</i> is the sole dominating shrub except where a shallow water table occurs. Associated shrubs may include <i>Ribes cereum var. cereum</i> and <i>Arctostaphylos uva-ursi</i>. The herb layer is typified by <i>Festuca idahoensis</i> with lesser amounts of <i>Carex rossii, Achnatherum occidentale, Elymus elymoides, Penstemon cinicola</i>, and <i>Lupinus caudatus</i>. 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. Fire maintains <i>Pinus contorta var. latifolia</i> forests in this area.
