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 <i>Chamaecyparis lawsoniana</i> and <i>Pseudotsuga menziesii</i> with a significant component of <i>Tsuga heterophylla</i>. These trees are the only ones that occur with consistency in this association. Occasional individuals of <i>Abies grandis</i> are also present. Immature conifer cover averages 33%, while seedlings and saplings have the lowest density of any <i>Chamaecyparis lawsoniana</i> association. The shrub layer is very well-developed with 93% cover with <i>Gaultheria shallon</i> and <i>Rhododendron macrophyllum</i> dominating. Other shrubs which show maximal development are <i>Mahonia nervosa (= var. nervosa), Vaccinium ovatum, Mahonia aquifolium, Corylus cornuta</i>, and <i>Acer circinatum</i>. The herbaceous layer is poorly developed, though <i>Polystichum munitum</i> does maintain fairly high cover values.
