Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Hemlock - Douglas-fir / Cascade Barberry - Little Prince''s-pine Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This western hemlock forest of Washington and Oregon has a canopy dominated by Tsuga heterophylla or codominated by that species and Pseudotsuga menziesii. The latter and Thuja plicata are almost always present. Thuja plicata is often prominent to occasionally codominant. Abies amabilis is frequent in small amounts. The understory is always relatively sparse. Mahonia nervosa is always present in small amounts. Chimaphila menziesii, Chimaphila umbellata, or Corallorhiza spp. are present and diagnostic. Vaccinium parvifolium and Vaccinium alaskaense are also usually present. This association occurs mostly at middle elevations on mid to upper slopes in the western Cascades and in the eastern to northern Olympics. Sites have well-drained, often shallow soils. These are relatively dry, cool sites compared to average Tsuga heterophylla sites.
