Name: Abies amabilis - Tsuga mertensiana / Vaccinium membranaceum / Rubus lasiococcus Forest
Reference: NatureServe Biotics 2019
Description: This Pacific silver fir - mountain hemlock forest of Washington and possibly Oregon has a canopy typically codominated by <i>Tsuga mertensiana</i> and <i>Abies amabilis</i>. The former has over 10% total cover and the latter usually dominates tree regeneration. <i>Callitropsis nootkatensis</i> and <i>Abies lasiocarpa</i> are commonly present and sometimes prominent to codominant. The shrub layer varies from sparse to dense and is characterized by the presence to dominance of <i>Vaccinium membranaceum</i>. Other shrubs, if present, are low in cover. The herb layer varies from sparse to well-developed. <i>Rubus lasiococcus</i> and <i>Rubus pedatus</i> are often present. <i>Erythronium montanum</i> sometimes dominates a well-developed herb layer. This association occurs at high elevations in the Cascade Range and Olympic Mountains. Soils are well-drained and relatively dry. In the northern portion of this association’s range, aspects tend to be southerly and in the southern portion the aspects tend to be northerly. Many natural-origin stands occur on protected lands; however, some non-protected stands are subject to logging and development.
