Name: Pinus ponderosa / Purshia tridentata / Carex geyeri Woodland Reference: Western Ecology Working Group of... Description: This woodland is known from the Ochoco Range and southern Blue Mountains of eastern Oregon and is reported from California and may occur in Washington. It is found between 1500-1650 m (4800-5400 feet) elevation on southerly aspects up to 25% slope. Soils are loams with varying amounts of silt, sand, and clay. Pinus ponderosa is the sole tree, averaging 42% cover. Purshia tridentata is the dominant shrub (13% cover) with minor amounts of Mahonia repens (2% cover) and occasional Cercocarpus ledifolius (4% cover), Symphoricarpos albus (3% cover), and Ceanothus velutinus (2% cover). Carex geyeri (37% cover) dominates the herb layer with occasional Achillea millefolium and Carex rossii. Periodic fires limit Purshia tridentata but maintain Pinus ponderosa.  Accession Code: VB.CC.23440.PINUSPONDEROSAP Plot-observations of this Community Concept: 0
