CNVC00023 occurs on rich, moist high fluvial benches on the floodplains of larger streams and rivers along the southern mainland coast of British Columbia. On average, flooding occurs every 5 or more years. Soils are derived from fluvial materials and have a fluctuating water table. This endemic, mixed coniferous and deciduous forest association has a multi-layered overstory consisting of big-leaved maple (Acer macrophyllum), black cottonwood (Populus balsamifera ssp. trichocarpa) and Sitka spruce (Picea sitchensis), often with red alder (Alnus rubra). The well-developed shrub layer is dominated by salmonberry (Rubus spectabilis), vine maple (Acer circinatum), and devil's club (Oplopanax horridus). The herb layer is characterized by two-leaved false Soloman's seal (Maianthemum dilatatum) with Hooker's fairybells (Prosartes hookeri), common lady fern (Athyrium filix-femina), and mountain sweet-cicely (Osmorhiza berteroi). The poorly developed moss layer consists primarily of leafy mosses (Mnium spp.).
