CNVC00237 is a boreal hardwood forest Association that occurs in Quebec and on insular Newfoundland. It has a closed canopy dominated by paper birch (Betula papyrifera), usually with a minor component of black spruce (Picea mariana) and/or balsam fir (Abies balsamea). The well-developed to dense shrub layer includes regeneration of these tree species as well as serviceberries (Amelanchier spp.) and green alder (Alnus viridis), along with the heath species velvet-leaved blueberry (Vaccinium myrtilloides), early lowbush blueberry (V. angustifolium), common Labrador tea (Rhododendron groenlandicum) and sheep laurel (Kalmia angustifolia). The herb layer can vary from poorly developed to dense and usually includes low cover of bunchberry (Cornus canadensis), wild lily-of-the-valley (Maianthemum canadense), yellow clintonia (Clintonia borealis), northern starflower (Lysimachia borealis) and creeping snowberry (Gaultheria hispidula). Moss layer development is poor to moderate, usually consisting of patches of red-stemmed feathermoss (Pleurozium schreberi). CNVC00237 occurs in a region with a humid to very humid, continental to maritime boreal climate, usually on mesic, nutrient-poor to medium sites. It is an early seral condition that typically follows fire. There are five subassociations: Alnus viridis, Rhododendron groenlandicum, Vaccinium angustifolium, Pleurozium schreberi and Kalmia angustifolia.
