CNVC00015 is a mixedwood forest association that occurs on sites with strongly fluctuating water tables within the Georgia Basin of coastal British Columbia from sea level to approximately 150 m, and on similar sites in pockets of Oregon and Washington. These communities have a closed mixed deciduous and coniferous overstory, comprising grand fir (Abies grandis), western red cedar (Thuja plicata), big-leaved maple (Acer macrophyllum), and red alder (Alnus rubra). The moderately shrubby understory is dominated by high cover of Indian plum (Oemleria cerasiformis), with low cover of thin-leaved snowberry (Symphoricarpos albus). A well-developed herb layer is characterized by western sword fern (Polystichum munitum), but also includes three-leaved foamflower (Tiarella trifoliata), and Pacific blackberry (Rubus ursinus). A moderately well-developed moss layer is dominated by slender beaked moss (Eurhynchium praelongum).
