CNVC00244 is a boreal coniferous forest Association that ranges from Saskatchewan to Ontario. It has an open to moderately closed tree layer of black spruce (Picea mariana) and jack pine (Pinus banksiana), usually with black spruce dominant. Shrub and herb layers are poorly developed, with low abundance of black spruce, velvet-leaved blueberry (Vaccinium myrtilloides) and common Labrador tea (Rhododendron groenlandicum) in the shrub layer and lingonberry (V. vitis-idaea) in the 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 red-stemmed feathermoss (Pleurozium schreberi) and Cladonia lichens are also present. CNVC00244 occurs mainly on dry, nutrient-poor sites in a region with a subhumid continental boreal climate. The dynamics of CNVC00244 are driven by fire. It can be the first cohort after fire or succeed earlier seral conditions. Time since fire and site conditions can affect the relative dominance of black spruce and jack pine in each stand of this Association.
