CNVC00209 is a boreal coniferous forest Association that occurs in Ontario and Quebec. It has a moderately closed to closed canopy dominated by jack pine (Pinus banksiana), with black spruce (Picea mariana) as the main companion species. The shrub layer is well developed to dense with abundant regenerating black spruce and heath species, especially sheep laurel (Kalmia angustifolia) but also velvet-leaved blueberry (Vaccinium myrtilloides), early lowbush blueberry (V. angustifolium) and common Labrador tea (Rhododendron groenlandicum). Willows (Salix spp.) are usually present but not abundant. The herb layer is sparse; only creeping snowberry (Gaultheria hispidula) and bunchberry (Cornus canadensis) are common. A well-developed moss layer dominated by red-stemmed feathermoss (Pleurozium schreberi) further characterizes this Association. CNVC00209 occurs in a region with a humid continental boreal climate on mesic, nutrient-poor to medium sites. It typically establishes as the first cohort after fire. Four subassociations are distinguished: typic, inops, Kalmia angustifolia and Rhododendron groenlandicum.
