CNVC00349 is a boreal hardwood forest Association that occurs in Newfoundland and Labrador. It has a closed canopy dominated by paper birch (Betula papyrifera), sometimes with trembling aspen (Populus tremuloides) as a codominant, and often minor components of balsam fir (Abies balsamea), black spruce (Picea mariana) and/or red maple (Acer rubrum). It is one of the most floristically diverse forest Associations in the province. The shrub layer is usually moderately developed and typically includes American mountain-ash (Sorbus americana) and regenerating balsam fir and black spruce. The herb layer is dense and relatively diverse. It usually includes bunchberry (Cornus canadensis), yellow clintonia (Clintonia borealis), twinflower (Linnaea borealis), wild lily-of-the-valley (Maianthemum canadense), northern starflower (Lysimachia borealis), dwarf raspberry (Rubus pubescens), spinulose wood fern (Dryopteris carthusiana) and large-leaved goldenrod (Solidago macrophylla). The forest floor cover is mainly broad-leaf litter, so the moss layer is sparse, with only minor cover of (primarily) common broom moss (Dicranum scoparium) and red-stemmed feathermoss (Pleurozium schreberi). CNVC00349 occurs in a region with a very humid maritime boreal climate on moist, nutrient-rich sites. These are some of the most productive sites in Newfoundland and Labrador. CNVC00349 is an early seral condition that typically establishes after fire.
