Name: Tsuga heterophylla / Vaccinium ovatum Forest Reference: Western Ecology Working Group of... Description: Pseudotsuga menziesii dominates the canopy. Tsuga heterophylla and Thuja plicata may occur in the canopy and regeneration layers. Stands of this association do not necessarily contain Tsuga heterophylla. In addition, Alnus rubra and Acer macrophyllum are sometimes present. The shrub layer is dense, usually occupying about 75% of the forest floor. Vaccinium ovatum is always present with cover averages of 20%. Other common shrubs include Gaultheria shallon, Vaccinium parvifolium, Acer circinatum, Mahonia nervosa (= Berberis nervosa), and small amounts of Rubus spectabilis. Polystichum munitum dominates the herb layer and Galium triflorum, Trillium ovatum, Blechnum spicant, Oxalis oregana and Claytonia sibirica are often present at low cover. This association is only found in the Coast Range and occurs most often on steep, south- or west-facing slopes and ridges. Soil depth averages 48 inches with 36 inches of effective rooting depth.  Accession Code: VB.CC.20580.TSUGAHETEROPHYL Plot-observations of this Community Concept: 0
