Name: Abies amabilis - (Pseudotsuga menziesii, Tsuga heterophylla) / Rhododendron macrophyllum Forest Reference: NatureServe Biotics 2019 Description: This Pacific silver fir forest occurs in the east-central and especially northeastern Olympic Mountains of Washington. It is most abundant in western Oregon. The canopy is usually dominated or codominated by <i>Tsuga heterophylla</i>. <i>Pseudotsuga menziesii</i> and/or <i>Abies amabilis</i> usually codominate. <i>Abies amabilis</i> dominates or codominates tree regeneration and contributes over 10% total cover. The often dense tall-shrub layer is dominated or codominated by <i>Rhododendron macrophyllum</i>. <i>Mahonia nervosa</i> is usually present and occasionally codominates the a dwarf-shrub stratum. <i>Vaccinium alaskaense</i> is often present and sometimes prominent to codominant. <i>Gaultheria shallon</i> or <i>Acer circinatum</i> are occasionally prominent to codominant. The herb layer is typically sparse. <i>Linnaea borealis</i> is frequent and sometimes prominent. This association occurs at middle elevations. Sites have well-drained soils and occur on a variety of slopes. Many natural-origin stands occur on protected lands; however, non-protected stands are subject to logging and development.  Accession Code: urn:lsid:vegbank.org:commConcept:34307-{0A3D120D-88DD-4466-A683-291B17655C13} Plot-observations of this Community Concept: 0
