CNVC00208 is a boreal coniferous forest Association that occurs in Manitoba and Ontario. It has a moderately closed canopy of black spruce (Picea mariana) and/or jack pine (Pinus banksiana), usually with black spruce dominant. The moderately to well-developed shrub layer usually includes regenerating black spruce and balsam fir (Abies balsamea) and blueberries, both velvet-leaved blueberry (Vaccinium myrtilloides) and early lowbush blueberry (V. angustifolium). The herb layer is poorly to well developed, depending on subassociation. Bunchberry (Cornus canadensis), wild lily-of-the-valley (Maianthemum canadense) and twinflower (Linnaea borealis) are common. A well-developed moss layer dominated by red-stemmed feathermoss (Pleurozium schreberi), with minor amounts of wavy-leaved broom moss (Dicranum polysetum) and knight’s plume moss (Ptilium crista-castrensis), further characterizes this Association. CNVC00208 occurs in a region with a continental boreal climate that grades from subhumid in the western portion of its range to humid in the east. It is found on dry to moist, nutrient-poor to medium sites. It can be the first cohort after fire or succeed earlier seral conditions. Two subassociations are distinguished, typic and Diervilla lonicera.
