CNVC00300 is a boreal wetland coniferous forest Association that occurs in Quebec. It has a moderately closed canopy of tamarack (Larix laricina) and black spruce (Picea mariana). Speckled alder (Alnus incana) dominates the dense shrub layer, which also typically contains black spruce, tamarack and balsam fir regeneration, common Labrador tea (Rhododendron groenlandicum), velvet-leaved blueberry (Vaccinium myrtilloides), sheep laurel (Kalmia angustifolia) and willows (Salix spp.). The herb layer is usually moderately developed, typically including sedges (Carex spp.), creeping snowberry (Gaultheria hispidula), bunchberry (Cornus canadensis), goldthread (Coptis trifolia), grasses (Poaceae) and three-leaved false Solomon’s seal (Maianthemum trifolium). A well-developed moss layer dominated by peat mosses (Sphagnum spp.), helps to characterize this Association. CNVC00300 occurs on wet, nutrient-medium to rich sites mainly in a region with a humid continental boreal climate. Substrates are usually organic soils formed from slowly decomposing graminoid litter and Sphagnum mosses. CNVC00300 can be the first cohort after fire or succeed a pure tamarack condition. There are three subassociations: typic, Rhododendron groenlandicum and Larix laricina.
