Northern Ontario Plant DatabaseNorthern Ontario Vegetation Type (V-type)Summary: A mixedwood stand dominated by sugar maple and hemlock, with yellow birch, red maple, beech, and white cedar occurring with less frequency. Regeneration is dominated by sugar and red maple, balsam fir, hemlock, beech, yellow birch, and some red oak. The tall shrub layer is dominated by striped maple and hobblebush, while Canada fly honeysuckle is the most common low shrub. The herb layer is dominated by wild sarsaparilla, wild lily-of-the-valley, star flower, rose twisted-stalk, bluebead lily, and Indian cucumber-root, as well as spinulose woodfern and ground pine. This vegetation type is similar to C-V16, however, C-V15 is characterized by the more common presence of red maple in the overstory and the occurrence of partridgeberry in the herb layer. Also, C-V15 lacks significant amounts of hairy Solomon's seal, Indian cucumber-root, and shining clubmoss. Soil & Ecosite Types: The Sugar Maple-Hemlock-Yellow Birch-Red Maple-Striped Maple Vegetation Type (C-V15) occurs most commonly on moderately fresh to moist soil types, including dry to moderately fresh (S3), fresh to very fresh (S7), and moderately moist to moist (S11) coarse loamy to silty soils. This vegetation type was described from sites scattered throughout Site Regions 4E and 5E. Like C-V16 and C-V17, this vegetation type can be found on ecosite types C-ES 28.2 (Sugar Maple-Hemlock-Yellow Birch, fresh to moist) and C-ES 28.1 (Sugar Maple-Hemlock-Yellow Birch, dry to moderately fresh). Rarely, it may also be found on ecosite types C-ES 27.2 (Sugar Maple-White Birch-Poplar-White Pine, fresh to moist) and C-ES35 (Lowland Hardwood).
