Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Hemlock - Douglas-fir / Alaska Blueberry / Redwood Sorrel Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This western hemlock forest - Douglas-fir of California, Washington and Oregon has a canopy codominated by Pseudotsuga menziesii and Tsuga heterophylla, with the latter dominating tree regeneration. The well-developed shrub layer is dominated or codominated by Vaccinium alaskaense. Acer circinatum and Vaccinium parvifolium are usually present to codominant. The well-developed herb layer is dominated by Oxalis oregana. Polystichum munitum is usually present to prominent. Cornus unalaschkensis is usually present. In the southwestern Olympic Mountains and possibly in the Carbon River valley at Mount Rainier, Washington, this association occurs at low elevations usually on gentle slopes.

Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: Fires are more frequent and the major factor distinguishing this association from ~Tsuga heterophylla / Vaccinium alaskaense / Oxalis oregana Forest (CEGL005587)$$. This type is distinguished from other associations with Oxalis by the prominence of both Pseudotsuga menziesii and Vaccinium alaskaense. The plots from the Olympics have a different set of associated species (e.g., less Acer circinatum and more Blechnum spicant and Rubus pedatus) than those from Oregon and the southern Washington Cascades. The plots described here appear to be transitional to CEGL005587 and are less distinct from that association than the ones from farther south.
