CNVC00013 is a closed-canopy, coniferous forest association that occurs at low elevations in the maritime climates of coastal British Columbia and south to western Oregon, USA. It occurs as small to medium patches on sites with soils that are moist for a significant part of the growing season, either through seepage (in the dryer part of the coast) or through precipitation (in the wetter, maritime parts of the coast). Overstories are closed and dominated by high cover of western hemlock (Tsuga heterophylla), with frequent and variable cover of western red cedar (Thuja plicata) and/or Douglas-fir (Pseudotsuga menziesii). The shrub layer is dominated by regenerating western hemlock and western red cedar, often with salal (Gaultheria shallon) and red huckleberry (Vaccinium parvifolium). Western sword fern (Polystichum munitum) dominates in the herb layer, with deer fern (Blechnum spicant) usually present. The moderately well-developed moss layer consists primarily of stairstep moss (Hylocomium splendens).
