CEGL007365 Pseudotsuga menziesii / Gaultheria shallon - Mahonia nervosa / Polystichum munitum Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir / Salal - Cascade Barberry / Western Swordfern Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: Canopy is dominated by Pseudotsuga menziesii or occasionally codominated by Acer macrophyllum, with little to no Tsuga heterophylla, Thuja plicata or Abies grandis present. Gaultheria shallon or Mahonia nervosa dominates or codominates the understory and Polystichum munitum is always prominent to dominant in the herb layer. Holodiscus discolor, Acer circinatum, and/or Corylus cornuta can form a prominent to codominant tall-shrub layer. Rubus ursinus (an increaser with disturbance), and Symphoricarpos albus or Rosa gymnocarpa are often prominent in the shrub or dwarf-shrub layers. Achlys californica, Achlys triphylla, Galium triflorum, Trientalis borealis ssp. latifolia, and Festuca subulata are frequently occurring herbs. This association occurs through much of lowland western Washington and in Oregon. These low-elevation sites are moderately dry to mesic and appear to be relatively nutrient-rich. Sites are flat to fairly steep, with aspects more often southerly to westerly. The plots represent a variety of slope positions, including plateaus/plains. Parent materials are variable, including glacial till, glacial outwash, and various bedrock (including ultramafics). Soil textures are loam to loamy sand, usually with abundant coarse fragments.

Floristics: The canopy is dominated by Pseudotsuga menziesii or occasionally codominated by Acer macrophyllum, with little to no Tsuga heterophylla, Thuja plicata or Abies grandis present. Gaultheria shallon or Mahonia nervosa (= Berberis nervosa) dominates or codominates the understory and Polystichum munitum is always prominent to dominant in the herb layer.
