CNVC00006 is an endemic moist maritime coniferous association that occurs up to approximately 700 mASL along the eastern slopes of the Vancouver Island Ranges of British Columbia and also on adjacent islands of the Discovery Islands Group. Slope positions vary from middle to lower, with gradients that are normally gentle. Well- to moderately well-drained, mesic to moist, comparatively rich, medium-textured soils are typical for this association. In this mature to old-forest stage, Douglas-fir (Pseudotsuga menziesii), western hemlock (Tsuga heterophylla), and western red cedar (Thuja plicata) characteristically dominate the canopy. The shrub layer is dominated by western hemlock regeneration, with moderate abundance of red huckleberry (Vaccinium parvifolium). There are a number of rich-site indicators, such as vanilla-leaf (Achlys triphylla), common oak fern (Gymnocarpium dryopteris), three-leaved foamflower (Tiarella trifoliata), and western sword fern (Polystichum munitum) in the herb layer. Oregon beaked moss (Eurhynchium oreganum) and lanky moss (Rhytidiadelphus loreus) are the main mosses.
