Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Western Hemlock - (Douglas-fir) / Alaska Blueberry / Western Cordilleran Bunchberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This western hemlock forest of Alaska, Washington and Oregon has a canopy dominated by Tsuga heterophylla or codominated by that species and Pseudotsuga menziesii. Thuja plicata is often prominent. Tsuga heterophylla dominates tree regeneration and Abies amabilis is often present in small amounts. The moderate to dense shrub layer is dominated or codominated by Vaccinium alaskaense. Vaccinium parvifolium is usually present and sometimes codominant. Gaultheria shallon and Acer circinatum are frequently present, the latter sometimes prominent. The herb layer is generally poorly developed. Blechnum spicant, Polystichum munitum, and Cornus unalaschkensis are usually present in small amounts. This association occurs at low to middle elevations on mid to toe slopes, valley bottoms and benches with well-drained, moist soils. This association occurs in the mountains of western Washington where it has been impacted by logging.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: The set of plots of this type from national parks in Washington has more Tiarella trifoliata than most citations for this association, indicating somewhat more moist sites. It also suggests a possible transition to ~Tsuga heterophylla - Abies amabilis / Vaccinium alaskaense / Tiarella trifoliata var. unifoliata Forest (CEGL005566)$$.
