CNVC00316 is a pioneer boreal hardwood forest Association that occurs on talus deposits on insular Newfoundland. It can have an open to closed canopy and is dominated by paper birch (Betula papyrifera), sometimes with a minor component of balsam fir (Abies balsamea). The shrub layer is usually moderately to well developed, and any of mountain maple (Acer spicatum), green alder (Alnus viridis) or balsam fir are sometimes abundant. Red-osier dogwood (Cornus stolonifera) and early lowbush blueberry (Vaccinium angustifolium) are often present. The herb layer can be dense and typically has numerous species in low abundance, often including dwarf raspberry (Rubus pubescens), large-leaved goldenrod (Solidago macrophylla), wild lily-of-the-valley (Maianthemum canadense), yellow clintonia (Clintonia borealis), northern starflower (Lysimachia borealis), three-flowered bedstraw (Galium triflorum) and rough-stemmed goldenrod (S. rugosa). Usually, there is a significant amount of exposed talus and moss cover is sparse. CNVC00316 occurs in a region with a very humid maritime boreal climate. It is described from moist, nutrient-rich sites in western Newfoundland but probably occurs on other sites elsewhere on insular Newfoundland and in the boreal region of Atlantic Canada where there are talus deposits in hilly or mountainous terrain.
