CNVC00201 is a boreal coniferous forest Association that occurs in Quebec and Ontario. It has a moderately closed canopy of jack pine (Pinus banksiana), with black spruce (Picea mariana) as a companion species. The dense shrub layer comprises black spruce and abundant ericaceous species, including sheep laurel (Kalmia angustifolia), early lowbush blueberry (Vaccinium angustifolium), velvet-leaved blueberry (V. myrtilloides) and common Labrador tea (Rhododendron groenlandicum). Willows (Salix spp.) are usually present but not abundant. The herb layer is virtually nonexistent. The moss and lichen layer is continuous and dominated by reindeer lichens (Cladina rangiferina, C. stellaris and C. mitis). Patches of red-stemmed feathermoss (Pleurozium schreberi) are also present. CNVC00201 occurs in a region with a humid continental boreal climate, usually on mesic, nutrient-poor sites. These are among the poorest sites capable of supporting tree-dominated vegetation in the region. CNVC00201 is an early seral condition with dynamics that are driven by fire. Two subassociations are distinguished, Pinus banksiana and Picea mariana.
