Type Concept Sentence: No Data Available

Common (Translated Scientific) Name: Douglas-fir - Western Hemlock / (Vine Maple) / Western Swordfern Forest

Colloquial Name: No Data Available

Hierarchy Level:  Association

Type Concept: This Douglas-fir - western hemlock forest of Washington, Oregon and possibly California has a canopy dominated by Pseudotsuga menziesii and/or Tsuga heterophylla. Both are always present and Tsuga heterophylla always contributes over 10% total cover. Tree regeneration is mostly Tsuga heterophylla. A well-developed tall-shrub layer dominated by Acer circinatum is often present. Other shrubs have low cover if they are present. The herb layer is dominated by Polystichum munitum. Other herbs are usually not very abundant. If present, Tiarella trifoliata, Blechnum spicant, Dryopteris expansa, and Athyrium filix-femina have very low percent cover. This association occurs in the western and southern Cascades and on the Olympic Peninsula, except for the western coastal plain. Elevations are relatively low and soils are well-drained and mesic to moist.
