Name: Tsuga heterophylla / Aralia nudicaulis Forest Reference: Western Ecology Working Group of... Description: This forested association occurs on warm, moist locations, some of the warmest locations in the Interior Northwest for Tsuga heterophylla communities. It occurs primarily on gentle stream benches, lower valley sideslopes and toeslopes, alluvial terraces and valley bottoms, 640 to 1219 m (2100-4000 feet) in elevation. Soils are typically well-drained, fine-textured with an ash layer, loam to silty loam, moist but never boggy. Parent materials range from glacial till, coarse alluvium to colluvium. This association is heavily forested. Total tree canopy cover ranges from 70-95%. Tsuga heterophylla is always present with 20-75% cover. Thuja plicata is often present with 10-40% average cover. Other trees are always present, but not in any consistent combination. Other tree species include Abies grandis, Betula papyrifera, Larix occidentalis, Pseudotsuga menziesii, and Pinus monticola. The shrub layer is relatively sparse with less than 10% total cover. Typical species include Paxistima myrsinites, Cornus sericea, Lonicera spp., Acer spp., and Linnaea borealis. The herbaceous layer is relatively lush, with 10-80% cover and floristically rich, but only Aralia nudicaulis, Clintonia uniflora, and Maianthemum stellatum have more than 5% cover. Aralia nudicaulis is not present in every stand in the literature, but it is expressed as the forb with the highest constancy and highest cover value within all sampled stands.  Accession Code: VB.CC.19956.TSUGAHETEROPHYL Plot-observations of this Community Concept: 0
