Name: Chamaecyparis lawsoniana - Tsuga heterophylla / Gaultheria shallon - Rhododendron macrophyllum Forest Reference: Western Ecology Working Group of... Description: This conifer forest association is found on mesic sites between 450-700 m elevation on sedimentary substrates in southwestern Oregon. Substrates are derived from sedimentary parent materials. Canopy cover averages 84% and is dominated by Chamaecyparis lawsoniana and Pseudotsuga menziesii with a significant component of Tsuga heterophylla. These trees are the only ones that occur with consistency in this association. Occasional individuals of Abies grandis are also present. Immature conifer cover averages 33%, while seedlings and saplings have the lowest density of any Chamaecyparis lawsoniana association. The shrub layer is very well-developed with 93% cover with Gaultheria shallon and Rhododendron macrophyllum dominating. Other shrubs which show maximal development are Mahonia nervosa (= var. nervosa), Vaccinium ovatum, Mahonia aquifolium, Corylus cornuta, and Acer circinatum. The herbaceous layer is poorly developed, though Polystichum munitum does maintain fairly high cover values.  Accession Code: VB.CC.17898.CHAMAECYPARISLA Plot-observations of this Community Concept: 0
