Northern Ontario Plant Database
Northern Ontario Vegetation Type (V-type)
Summary: A mixedwood stand dominated by jack pine, with considerable amounts of black spruce, trembling aspen, and/or white birch in the canopy. Balsam fir and white spruce, respectively, occurred in only 20% and 10% of sample plots. Black spruce, balsam fir, and trembling aspen regen are present in the shrub layer. The shrub layer is usually dominated by low shrubs, including blueberries, bush honeysuckle, and prickly wild rose. Occasionally, mountain alder may appear with the conifer regen in the tall shrub layer.
Dwarf shrubs, such as twinflower and creeping snowberry are common in the herb layer, along with the herbaceous characteristic boreal forest species. The forest floor is dominated by feathermoss carpets, but patches of broadleaf and conifer litter are also present.
The Jack Pine Mixedwood/Feathermoss V-type is similar to the Jack Pine/Ericaceous Shrub/Feathermoss type (NW-V29), but the latter can be distinguished by the pure, even-aged jack pine canopy.
Soil & Ecosite Types: The Jack Pine Mixedwood Feathermoss Vegetation Type (NW-V18) is found primarily on Ecosite Type ES 14 (Pine-Spruce Mixedwood, sandy soil). It occurs on rapidly-drained, dry to fresh, sandy or coarse-textured, upland, mineral soils (mainly S1, S2, and S3.
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.
