Name: Abies concolor - Pinus ponderosa / Purshia tridentata Woodland Reference: Western Ecology Working Group of... Description: This woodland community is found in the East Cascade region of central and southern Oregon and extreme northern California. Typical elevations are between 1250-1800 m (4100-5886 feet). It occurs on a high variety of slopes and aspects with coarse sand and loamy sand soils. <i>Pinus ponderosa</i> generally dominates south aspects while <i>Abies concolor</i> prevails on north aspects and higher elevations. <i>Purshia tridentata</i> is most common at lower slopes. At the upper elevations within its range, <i>Arctostaphylos patula</i> or <i>Ceanothus velutinus</i> may dominate. Common herbs include <i>Chamerion angustifolium (= Epilobium angustifolium), Apocynum androsaemifolium (= ssp. pumilum), Carex rossii</i>, and <i>Elymus elymoides ssp. elymoides (= Sitanion hystrix)</i>. This association becomes increasingly dominated by <i>Abies concolor</i> in the absence of fire, which typically kills the younger fire-sensitive firs.  Accession Code: VB.CC.34472.CEGL000259 Plot-observations of this Community Concept: 0
