Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir - Grand Fir / Cascade Barberry - Salal / Western Swordfern Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This type has a canopy Pseudotsuga menziesii and Abies grandis with Tsuga heterophylla present. Typically, Abies grandis and Acer macrophyllum dominate below the main canopy. Acer circinatum and Mahonia nervosa dominate the shrub layer. Achlys californica, Achlys triphylla, and Polystichum munitum are prominent indicators in the herb layer. As described in Oregon, this association often has Gaultheria shallon and Corylus cornuta in the shrub layer. Ground mosses are prominent. This association is found in the foothills surrounding the Willamette Valley in Oregon and can infrequently occur as far north as the Olympic Mountains. The plot representing this association in the Olympics was located on a southwest-facing terrace at 300 m (980 feet) elevation on a dry topographic position.
