Northern Ontario Vegetation Type (V-type)
Summary: A sugar maple-dominated hardwood stand with abundant sugar maple regeneration. Sugar maple provides > 40% cover in both the canopy and the understorey. Trembling aspen is quite common, providing 21-40% cover in 70% of the sample plots, while yellow birch and white spruce occur in 30% of the samples, with 21-40% cover. Balsam fir and white birch were present in only 10% of the samples.
The tall shrub layer has few species, with mountain maple and beaked hazel providing 21-40% cover, and choke cherry occurring occasionally with only 1% cover. Amongst low shrubs, bush honeysuckle provides 2-5% cover. The herb layer contains a variety of species, largeleaf aster occurs with the most frequency (6-10% cover), followed by sarsaparilla (2-5% cover), rose twisted-stalk, and fragrant bedstraw (1% or less cover). Of the characteristic boreal species, bluebead lily provides the most cover (2-5%), but bunchberry and twinflower have not been recorded from this vegetation type.
Ground pine is the most common clubmoss, with 6-10% cover; shining clubmoss, spinulose woodfern, and bracken fern are also present (1% or less cover). The moss layer is poorly developed due to the heavy deciduous litter, but dusky broom moss and Brachythecium spp. occur with less than 1% cover.
Soil and Ecosite Types: The Sugar Maple Vegetation Type (NE-V3) is found on acidic soils and most often (60% of samples) occurs on fresh loamy to silty soils (S9). Less frequently, it is found on fresh to moist loamy to silty soils (S11) or fresh to moist, coarse loamy soils (S7). The NE-V3 vegetation type occurs primarily on ecosite type ES 17 (Sugar Maple), but may also occur on ecosite types ES 16 (Yellow Birch), ES 19 (White Pine-Red Pine-Mixedwood), and ES 21 (White Pine-Coniferous Mixedwood).
