Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Hemlock / Western Swordfern - Redwood Sorrel Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This western hemlock forest of California, Oregon and Washington has a canopy that is usually dominated by Tsuga heterophylla. Pseudotsuga menziesii is occasionally present to codominant. The shrub layer is typically sparse to moderately dense. Vaccinium alaskaense, Vaccinium parvifolium, and Rubus spectabilis are usually present. The latter is sometimes prominent. Acer circinatum is occasionally prominent to codominant. The well-developed herb layer is codominated by Polystichum munitum and Oxalis oregana (or occasionally just by the latter). Blechnum spicant is almost always present and occasionally prominent. Tiarella trifoliata is often present. This association occurs at low elevations on valley bottoms, lower slopes and, less commonly, mid slopes. Soils are deep, well-drained, and moist.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: This association is distinguished from similar ones by the absence of Pseudotsuga menziesii; or the presence of Pseudotsuga menziesii and Picea sitchensis with a combination of presence of Vaccinium alaskaense or Blechnum spicant and absence of Mahonia nervosa.
