CNVC00002 is a late seral (mature and climax) association that occurs at low elevations in the submaritime and subcontinental areas of coastal southwestern British Columbia on nutrient-deficient dry crests and upper slopes with shallow soils, or on coarse-textured glacial outwash. It has a moderately open coniferous canopy dominated by moderate cover of Douglas-fir (Pseudotsuga menziesii) and lodgepole pine (Pinus contorta), often with western hemlock (Tsuga heterophylla). The understory is characterized by moderate cover of mountain huckleberry (Vaccinium membranaceum), common bearberry (Arctostaphylos uva-ursi) and western hemlock regeneration. The moss / lichen layer is diverse and well-developed, often with high cover of red-stemmed feather moss (Pleurozium schreberi) and clad lichens (Cladonia spp.). Stands of this association typically originate from infrequent stand replacing fires (perhaps every few hundred years) or windthrow.
