Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Hemlock - Pacific Silver Fir / Redwood Sorrel - Deer Fern Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This western hemlock - Pacific silver fir forest of Washington and Oregon has a canopy dominated by Tsuga heterophylla or codominated by that species and Abies amabilis. Abies amabilis dominates or codominates tree regeneration and occupies over 10% total cover. Pseudotsuga menziesii is occasionally present to prominent. The shrub layer varies from sparse to moderately dense. When it is more developed (only occasionally), it is dominated by Gaultheria shallon or Vaccinium alaskaense. Vaccinium parvifolium and Rubus spectabilis are present or occasionally prominent. The usually well-developed herb layer is dominated or codominated by Oxalis oregana. Polystichum munitum is usually present and occasionally codominant. Blechnum spicant is almost always present to occasionally prominent. Maianthemum dilatatum or Tiarella trifoliata is frequently present. This association occurs extensively on the western Olympic Peninsula at low to moderate elevations. Sites occupied have relatively deep, well-drained, moist soils, and occur on a variety of topography. This association has been impacted by logging.
