Northern Ontario Vegetation Type (V-type)
Summary: A conifer stand dominated by black spruce, and occasionally with jack pine, in the canopy. Balsam fir, white spruce, and white birch occur infrequently in the overstorey. Black spruce is the most common species in the regeneration. The poor shrub layer is composed entirely of low shrubs, including blueberries and Labrador tea.
The herb layer is also very poor, with only creeping snowberry, bunchberry, and wild lily-of-the-valley reported. The forest floor is covered by a continuous carpet of feathermosses.
Soil & Ecosite Types: The Black Spruce/Feathermoss Vegetation Type (NW-V33) occurs most commonly on Ecosite Types ES 20 (Spruce-Pine/Feathermoss, fresh, sandy-coarse loamy soil), ES 22 (Spruce-Pine/Feathermoss, moist, sandy-coarse loamy soil), ES 26 (Spruce-Pine/Feathermoss, fresh, fine loamy-clayey soil), and ES 31 (Spruce-Pine/Feathermoss, moist, silty-clayey soil). It occurs most often on fresh, coarse-textured mineral soils (including S1, S2, S3, S6, S7, and S8), but also occurs frequently on shallow soils (SS6 and SS8).
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.
