Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Western Hemlock / Western Swordfern - Deer Fern Forest

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This western hemlock forest of Oregon and Washington and possibly California has a canopy dominated by Tsuga heterophylla. Pseudotsuga menziesii is occasionally prominent. The shrub layer ranges from sparse to moderately dense. Vaccinium alaskaense, Vaccinium parvifolium, Gaultheria shallon, Rubus spectabilis, and Menziesia ferruginea all occur in most stands. Only the Vaccinium spp. are sometimes prominent. The well-developed herb layer is codominated by Polystichum munitum and Blechnum spicant. The environmental characteristics of this association have not been well described. It has been found at low elevations on moist sites with well-drained, deep soils on the western Olympic Peninsula and at Mount Rainier, Washington.
