CEGL007333 Pseudotsuga menziesii - Tsuga heterophylla / Gaultheria shallon / Xerophyllum tenax Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Douglas-fir - Western Hemlock / Salal / Common Beargrass Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: The canopy is dominated by Pseudotsuga menziesii and/or Tsuga heterophylla. Both of these species are always present. Thuja plicata is occasionally present to prominent. The well-developed shrub layer is always dominated by Gaultheria shallon. Mahonia nervosa is usually present and often prominent. Acer circinatum often forms a prominent taller shrub layer often with Vaccinium parvifolium. The herb layer is dominated by Xerophyllum tenax, which always occupies over 5% cover. Linnaea borealis is frequent. This association occurs on the southeastern Olympic Peninsula, slopes of Mount Rainier and southern Cascades in Washington. Sites occupied are mid to upper slopes with shallow soils and mostly south to west aspects, or relatively flat with very coarse-textured glacial soils (latter only on Olympic Peninsula). Sites are located at low to especially middle elevations.
