Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Hemlock - Pacific Silver Fir - (Western Red-cedar) / Alaska Blueberry / Deer Fern Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: The canopy is dominated by a somewhat variable mixture of Tsuga heterophylla, Abies amabilis, and Thuja plicata. The latter is sometimes absent. Tree regeneration is dominated by Abies amabilis and Tsuga heterophylla. The well-developed shrub layer is dominated by Vaccinium alaskaense, with Vaccinium parvifolium prominent to codominant and Menziesia ferruginea usually prominent. The well-developed herb layer is dominated or codominated by Blechnum spicant. Cornus unalaschkensis is usually present to prominent. Oxalis oregana and Gaultheria shallon occupy low cover if they are present. This type occurs on relatively moist, relatively nutrient-poor sites. This association occurs in a narrow environmental and geographic range in western Washington with only a few known occurrences.
