Common (Translated Scientific) Name: Western Hemlock - (Pacific Silver Fir) / Salal / Deer Fern Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This western hemlock forest of Washington has a tree canopy that is always dominated or codominated by Tsuga heterophylla. Abies amabilis is sometimes present to codominant. Either of these species can dominate tree regeneration. Thuja plicata is occasionally present, but never codominant. Gaultheria shallon dominates the well-developed shrub layer. Vaccinium alaskaense, Vaccinium parvifolium, and Menziesia ferruginea are usually present to prominent or occasionally codominant. The herb layer is variable in total cover. Blechnum spicant is always present and often prominent or dominating the herb layer. Polystichum munitum is absent or present only in low amounts. This association occurs on the western Olympic Peninsula including the western Olympic Mountains and the western slopes of the Willapa Hills. It occurs at low elevations on well-drained soils and a variety of landforms including gentle to steep slopes, ridgetops, and rolling plains. Many occurrences have been fragmented by and altered by timber harvests.
