Northern Ontario Vegetation Type (V-type)
Summary: A conifer-dominated mixedwood stand with white cedar providing 21-40% cover in the overstorey. Several other conifer and hardwood species also occur, including white spruce, balsam fir, and white birch. Regeneration is dominated by white cedar (6-10% cover), followed by white spruce, balsam fir, and white birch (each 2-5% cover).
The shrub layer is moderately-rich and dominated by mountain maple (11-20% cover), with showy mountain ash and Canada honeysuckle each providing 2-5% cover. In moister sites of this vegetation type, speckled alder may provided 21-40% cover. The herb layer is rich, with spinulose shield fern and oak fern providing as much cover (2-5%) as dwarf raspberry, naked mitrewort, wild sarsaparilla, and the characteristic boreal forest species. Sedges are also common, providing 6-10% cover. A variety of other herbs, grasses, and pteridophytes are also present, each providing no more than 5% cover in 1/3 to 2/3 of sample plots.
The moss layer is dominated by patches of stairstep moss (2-5% cover) and Schreber's feathermoss (1% cover) scattered amongst the coniferous and deciduous leaf litter. In fewer than 2/3 of the sample plots, shaggy moss and sickle moss also provided 2-5% cover. Other feathermoss species and acrocarpous mosses occur with less than 1% cover.
Soil and Ecosite Types: The White Cedar-White Spruce-Mountain Maple-Fern Vegetation Type (NE-V14) is found most commonly on moist, shallow organic soils (S15, S16) and less commonly on deep organic soils (S19), and fresh to moist, non-calcareous loamy to silty (S7, S9, S11) or loamy to clayey (S14) soils. This vegetation type may occur on ecosite types ES9r (White Spruce-Balsam Fir-White Cedar-Moist Soil-Species Rich), ES10 (Trembling Aspen-Black Spruce-Balsam Poplar-Moist Soil), ES13r (White Cedar-Black Spruce-Organic Soil-Species Rich), and ES21 (White Pine-Coniferous Mixedwood).
