Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Mountain Hemlock - Pacific Silver Fir / Alaska Blueberry / Strawberry-leaf Raspberry Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This mountain hemlock - Pacific silver fir forest of Washington and British Columbia has a canopy codominated by Tsuga mertensiana and Abies amabilis. Tsuga heterophylla is often prominent and Callitropsis nootkatensis is occasionally prominent to dominant. The typically well-developed shrub layer is at least codominated by Vaccinium alaskaense. Vaccinium ovalifolium or Vaccinium membranaceum are usually present and occasionally codominant. The herb layer is variable. Rubus pedatus is the most consistent herb and is sometimes prominent. Erythronium montanum, Clintonia uniflora, and Xerophyllum tenax are occasionally prominent to codominant but inconsistent in occurrence. Tiarella trifoliata var. unifoliata, Streptopus lanceolatus var. curvipes, and Maianthemum dilatatum are absent or present with very low cover. In the Cascades and Olympic Mountains of Washington, this association occurs at middle to high elevations on a variety of well-drained sites that are moderately dry to moist.
