Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Douglas-fir - (Red Alder, Western Hemlock) / Salmonberry Forest

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This is conifer-dominated or mixed conifer-hardwood association occurs in Oregon and Washington. The canopy is dominated by Pseudotsuga menziesii, Alnus rubra, and/or Tsuga heterophylla. One or more of the conifers is always at least codominant. The well-developed shrub layer is dominated or codominated by Rubus spectabilis. Gaultheria shallon or Acer circinatum are sometimes codominant. The well-developed herb layer is dominated or codominated by Polystichum munitum. Oxalis oregana can be codominant in the western Olympics. Claytonia sibirica and Galium triflorum are usually present. As defined, this association does not occur on floodplains. Sites are on lower slopes or toeslopes or valley bottoms with moist, but not wet, soils but are otherwise not well-described in Washington. Most of these stands are relatively young in age, having regenerated after fire, blowdown or logging.
