CNVC00249 is a boreal coniferous forest Association that ranges from Alberta to Ontario. It has a moderately closed canopy dominated by black spruce (Picea mariana), usually with lower abundance of jack pine (Pinus banksiana). The shrub layer varies from poorly to well developed but typically includes regenerating black spruce and the ericaceous species velvet-leaved blueberry (Vaccinium myrtilloides) and common Labrador tea (Rhododendron groenlandicum). The herb and dwarf shrub layer is sparse; lingonberry (V. vitis-idaea) is the only common species. A continuous moss layer dominated by red-stemmed feathermoss (Pleurozium schreberi), with lower abundance of stairstep moss (Hylocomium splendens), knight’s plume moss (Ptilium crista-castrensis), wavy-leaved broom moss (Dicranum polysetum) and reindeer (Cladina spp.) and Cladonia lichens, further characterizes this Association. CNVC00249 occurs on dry to moist, nutrient-poor to medium sites in a region with a subhumid continental boreal climate. It can be the first cohort after fire or succeed earlier seral conditions.
