CEGL000217 Tsuga heterophylla - Abies amabilis - Pseudotsuga menziesii / Mahonia nervosa Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Hemlock - Pacific Silver Fir - Douglas-fir / Cascade Barberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association is found in the western Cascades and Olympic Mountains at middle elevations typically on moderate to steep slopes with south- to west-facing aspects and well-drained soils. The canopy is typically codominated by Tsuga heterophylla, Abies amabilis, and Pseudotsuga menziesii. In any one stand, one or more species may be less abundant. Abies amabilis always occupies over 10% total cover and usually codominates tree regeneration with Tsuga heterophylla. The shrub layer is usually moderately dense and is dominated by Mahonia nervosa. Vaccinium alaskaense and Vaccinium parvifolium are usually present. The herb layer is typically sparse and may be absent. Cornus unalaschkensis and Linnaea borealis are usually present.
