Name: Abies lowiana - Picea breweriana / Vaccinium membranaceum / Goodyera oblongifolia Forest Reference: NatureServe Biotics 2019 Description: This association has been described only from southwestern Oregon, on the Illinois Valley and Applegate Districts of the Siskiyou and Rogue River national forests. It possibly occurs in the adjacent region of northern California, but has not been documented from there. The association is most common on northern aspects occurring within a narrow elevational band from 1220 to 1525 m (4000-5000 feet). Sites are usually concave, relatively cool and moist. This is a structurally diverse coniferous forest, with a continuous vertical structure difficult to categorize as layers. The canopy is dominated by <i>Abies lowiana, Picea breweriana</i>, and <i>Pseudotsuga menziesii</i>. An important subcanopy dominant is <i>Quercus sadleriana</i>. The dominant shrubs are <i>Vaccinium membranaceum</i> and <i>Chimaphila umbellata</i>. The herbaceous layer has moderate cover (25%), with only the perennial <i>Goodyera oblongifolia</i> present in all stands. There is a nonvascular ground cover of mosses, with 18% cover. Graminoids are lacking. <i>Picea breweriana</i> is a Klamath-Siskiyou endemic.  Accession Code: urn:lsid:vegbank.org:commConcept:28961-{81CB822B-DEB5-48F7-AFEA-C5C35DFCC769} Plot-observations of this Community Concept: 0
