Northern Ontario Vegetation Type (V-type)Summary: A mixedwood stand dominated by hemlock and yellow birch, with cedar, balsam fir, sugar and red maple, and white spruce occurring with less frequency in the canopy. A variety of conifer and hardwood species occur in the subcanopy with 30-50% frequency. The regeneration layer is dominated by balsam fir, red and sugar maple, hemlock, and yellow birch. The occassional occurrence of red spruce in this vegetation type is mentioned in the C-FEC manual, but is not included in their species list. Striped maple, mountain maple, and beaked hazel dominate the tall shrub layer, while Canada fly honeysuckle and hobblebush are the most common low shrubs. The herb layer is fairy rich, with spinulose woodfern listed as the most common species, followed by several forbs, including wild lily-of-the-valley, bluebead lily, wild sarsaparilla, starflower, goldthread, wood sorrel, and rose twisted-stalk. Shining clubmoss and ground pine complete the species list from the herb layer. This vegetation type is similar to C-V19, however, C-V18 is characterized by the common presence of hobblebush, goldthread, wood sorrel, bunchberry, and shining clubmoss. Soil & Ecosite Types: The Hemlock-Yellow Birch-Goldthread-Wood Sorrel Vegetation Type (C-V18) occurs most commonly on 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 mainly from Site Regions 5E, including Site District 5E-9 (southern Algonquin Park area) and others; less than 10% of sample plots were from Site Region 4E. Like C-V19, this vegetation type can be found on ecosite types C-ES 30.2 (Hemlock-Yellow Birch, fresh to moist), C-ES 30.1 (Hemlock-Yellow Birch, dry to moderately fresh). Rarely, it may also be found on ecosite type C-ES 35 (Lowland Hardwood, fresh to very moist). Note: In sample plots, species listed below occurred with 50% frequency or more, except for those in square brackets, which occurred with 30-49% frequency.
