Name: Thuja plicata / Linnaea borealis Forest
Reference: Western Ecology Working Group of...
Description: This evergreen forest association is found on the west slope of the Oregon Cascades, on the east slope of the Cascades near Mount Hood, and possibly extending into Washington. Stands generally occur along stream margins between 1100-1400 m elevation on all aspects. Upland stands are usually indicative of a perched water table. Soils are fine, sandy clay loams with weak subangular, blocky structure. The tree canopy is dominated by <i>Thuja plicata</i>, averaging between 30-50% cover. <i>Abies grandis</i> and <i>Picea engelmannii</i> are common tree associates. Occasionally <i>Populus balsamifera ssp. trichocarpa (= Populus trichocarpa)</i> and/or <i>Populus tremuloides</i> may be conspicuous associates. <i>Linnaea borealis</i> is always present though cover values rarely exceed 5%. Other shrubs may include <i>Acer circinatum, Ribes lacustre, Mahonia nervosa</i>, and <i>Athyrium filix-femina</i>. The most common forb is <i>Maianthemum stellatum</i>. A rich and varied assortment of other shrubs and forbs is usually present.
