CEGL005539 Pseudotsuga menziesii - Tsuga heterophylla / Gaultheria shallon - Vaccinium parvifolium Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir - Western Hemlock / Salal - Red Huckleberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This Douglas-fir - western hemlock forest of California, Washington and Oregon has a canopy that is usually codominated by Pseudotsuga menziesii and Tsuga heterophylla, though in any one stand one or the other could be dominant. Occasionally Pseudotsuga is entirely absent. Thuja plicata is usually prominent to occasionally codominant. The well-developed shrub layer is dominated by Gaultheria shallon. Typically, no other shrubs are prominent, though Acer circinatum occasionally can be. Vaccinium parvifolium and Mahonia nervosa are usually present in small amounts. The herb layer is absent to rather sparse with Linnaea borealis the most frequent species. Blechnum spicant is usually absent, or if present, only in small amounts. In Washington, this association occurs on the western slopes of the Cascades and on the Olympic Peninsula. It is absent from the outer coastal strip and infrequent to rare on the western side of the Olympic Mountains. This association occupies relatively low to middle elevations and well-drained soils. These are moderately dry sites.

Classification Comments: This association is similar to ~Pseudotsuga menziesii - Tsuga heterophylla / Gaultheria shallon - Mahonia nervosa Forest (CEGL005538)$$ but is strongly dominated by Gaultheria shallon with no or only low cover of Mahonia nervosa and generally a less diverse, sparse understory.

Floristics: The canopy is usually codominated by Pseudotsuga menziesii and Tsuga heterophylla, though in any one stand one or the other could be dominant. Occasionally Pseudotsuga is entirely absent. Thuja plicata is usually prominent to occasionally codominant. The well-developed shrub layer is dominated by Gaultheria shallon. Typically, no other shrubs are prominent, though Acer circinatum occasionally can be. Vaccinium parvifolium and Mahonia nervosa (= Berberis nervosa) are usually present in small amounts.
