CNVC00127 is a boreal coniferous forest Association that ranges from Alberta to Ontario. It has an open tree layer of jack pine (Pinus banksiana) and a poorly developed shrub layer made up primarily of velvet-leaved blueberry (Vaccinium myrtilloides). Lingonberry (V. vitis-idaea) and common bearberry (Arctostaphylos uva-ursi) are the only common species in the poorly developed herb and dwarf shrub layer. The moss and lichen layer is well developed and dominated by reindeer lichens (Cladina mitis, C. stellaris and C. rangiferina). Patches of Cladonia lichens and red-stemmed feathermoss (Pleurozium schreberi) are also present. CNVC00127 occurs on dry, nutrient-poor sites in a region with a subhumid continental boreal climate. These are the driest, most nutrient-impoverished sites capable of supporting tree-dominated vegetation in the region. CNVC00127 is an early seral condition with dynamics that are driven by fire and limited by edaphic conditions.
