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. Pinus ponderosa generally dominates south aspects while Abies concolor prevails on north aspects and higher elevations. Purshia tridentata is most common at lower slopes. At the upper elevations within its range, Arctostaphylos patula or Ceanothus velutinus may dominate. Common herbs include Chamerion angustifolium (= Epilobium angustifolium), Apocynum androsaemifolium (= ssp. pumilum), Carex rossii, and Elymus elymoides ssp. elymoides (= Sitanion hystrix). This association becomes increasingly dominated by Abies concolor in the absence of fire, which typically kills the younger fire-sensitive firs.  Accession Code: VB.CC.24432.ABIESCONCOLORPI Plot-observations of this Community Concept: 0
