Name: Chamaecyparis lawsoniana / Rhododendron occidentale Forest Reference: Western Ecology Working Group of... Description: This is an open-canopy, coniferous forest found on metamorphic substrates, primarily serpentine and gneiss, in southwestern Oregon and northwestern California. It is found along the coast in Del Norte County, California, and adjacent Curry County, Oregon. These forests occur on toeslopes, lower slopes and stream terraces between 2500-3950 feet in elevation. The forests are old, approaching giant conifer status, although are less productive than most coastal Port Orford-cedar stands, with only moderate softwood volumes (the highest being about 10,000 cubic feet per acre). Chamaecyparis lawsoniana and Pseudotsuga menziesii dominate most stands. Pinus lambertiana and Lithocarpus densiflorus are present in most stands, but with fairly low cover. The understory is characterized by shrubs, with an average of 24% cover of Rhododendron occidentale. Other shrubs include Gaultheria shallon, Gaultheria humifusa, Mahonia nervosa, Corylus cornuta, Quercus vacciniifolia, and Rubus ursinus. No forbs or graminoids were found with much cover or consistency in stands, but Xerophyllum tenax, Carex species, Goodyera oblongifolia, and Chimaphila sp. are all reported. It is distinguished from similar associations by the lack of abundant herbaceous undergrowth and non-wetland, non-serpentine habitat.  Accession Code: VB.CC.25436.CHAMAECYPARISLA Plot-observations of this Community Concept: 0
