Common (Translated Scientific) Name: Mountain Hemlock - Pacific Silver Fir / Oval-leaf Blueberry / False Lily-of-the-Valley Forest
Colloquial Name: No Data Available
Hierarchy Level: Association
Type Concept: This association occurs at middle elevations. It occupies moist sites on gentle slopes in high precipitation zones. The canopy is codominated by Tsuga mertensiana and Abies amabilis. Tsuga heterophylla, Thuja plicata, and Callitropsis nootkatensis are frequent and one or more may be prominent to codominant. The well-developed shrub layer is dominated by Vaccinium alaskaense, sometimes with Vaccinium ovalifolium codominant. The diverse herb layer is at least codominated by Maianthemum dilatatum. Other frequently occurring species are Rubus pedatus, Clintonia uniflora, Cornus unalaschkensis, Blechnum spicant, and Streptopus lanceolatus var. curvipes.
