Northern Ontario Plant Database
Northern Ontario Vegetation Type (V-type)
Summary: A conifer stand dominated by white spruce and balsam fir in the canopy, often also with black spruce. Other tree species occurred in less than 30% of sample plots. Balsam fir dominates the regeneration layer. The rich shrub layer includes a variety of tall and low shrubs, though low shrubs are more common, especially bush honeysuckle. Tall shrubs include serviceberry, showy mountain ash, mountain maple, and beaked hazel, which occur in lower numbers than in NW-V24.
The herb layer includes all of the characteristic boreal forest species, plus dwarf raspberry, wild sarsaparilla, and goldthread. The presence of kidneyleaf violet indicates calcareous substrates or soils. The forest floor is dominated by carpets of feathermosses, with some conifer litter.
Soil & Ecosite Types: The White Spruce-Balsam Fir/Feathermoss Vegetation Type (NW-V25) can be found on Ecosite Types ES 17 (White Cedar, fresh-moist, coarse-fine loamy soil) and occasionally ES 21 (Fir-Spruce Mixedwood, fresh, coarse loamy soil). It occurs on fresh, well-drained, upland mineral soils (mainly S3, S4, and S6).
Note: The percentage of sample plots that contained overstorey tree species is given in square brackets after each scientific name. Other species are listed in order of frequency, according to the NW-FEC manual.
