Northern Ontario Vegetation Type (V-type)


NW-V27: Red Pine Conifer

Summary: A conifer stand dominated by red pine; the stands often with a pure canopy of red pine. A variety of other conifer species and white birch occurred in only 10-30% of sample plots. Balsam fir and black spruce are the most common tree species in the regeneration layer; other than an occasional serviceberry, tall shrubs are lacking. Generally, the shrub layer is relatively poor, with blueberries and bush honeysuckle dominating. However, stands in the Quetico area, often have a richer shrub layer, composed of mountain maple, beaked hazel, mountain alder, and bush honeysuckle. Stands farther north and west of Quetico have poorer, more open shrub layers dominated by blueberries.

The herb layer is relatively poor, with wild sarsaparilla, mountain rice grass, and only some of the characteristic boreal forest species present; starflower and bluebead lily are lacking. The forest floor is covered by a mixture of conifer litter and extensive patches of feathermoss species. Feathermoss cover is higher in western portions of northwestern Ontario than in eastern stands.

The NW-V13 Vegetation Type is most similar to NW-V27 (Red Pine Conifer), except that, in the latter type, white birch plays a minor role in the overstorey and other hardwood species are absent. NW-V13 probably represents a successional stage of NW-V27.

Soil & Ecosite Types: The Red Pine Conifer Vegetation Type (NW-V27) occurs most commonly in the Quetico/Rainy River/Dryden regions of northwestern Ontario. It is found on Ecosite Types ES 11 (Red Pine-White Pine-Jack Pine, very shallow soil), ES 15 (Red Pine-White Pine: sandy soil), ES 18 (Red Pine-White Pine: fresh, coarse loamy soil), and ES 24 (Red Pine-White Pine: fresh, fine loamy soil). This V-type occurs on dry to fresh, rapidly drained, non-calcareous, coarse-textured, upland mineral soils (including S1, S2, S3, and occasionally S4 and SS6).

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.
