CNVC00019 is a forest association that occurs on rich, mesic or moist sites in coastal British Columbia, along drainages of the Fraser River, and in the eastern Coast Mountains. Elevations range from sea level to approximately 650 m. This association is characterized by a closed canopy dominated by high cover of western red cedar (Thuja plicata), western hemlock (Tsuga heterophylla), and Douglas-fir (Pseudotsuga menziesii). The shrub layer is dominated by moderate cover of vine maple (Acer circinatum) and regenerating western hemlock and western red cedar, with low cover of red huckleberry (Vaccinium parvifolium). The herb layer is mostly western sword fern (Polystichum munitum) with low cover of northern wood fern (Dryopteris expansa) and bracken (Pteridium aquilinum). The moss layer can be sparse to moderately well-developed, with stairstep moss (Hylocomium splendens), Oregon beaked moss (Eurhynchium oreganum) and leafy mosses (Rhizomnium spp. and Plagiomnium spp.) as predominant species.
