Northern Ontario Vegetation Type (V-type)
The herb layer is dominated by wild sarsaparilla, especially in eastern stands; most of the characteristic boreal forest species are present, except starflower. Largeleaf aster and cowwheat may also be present. The forest floor is covered by a combination of conifer litter and extensive feathermoss patches.
This vegetation type is similar to the Jack Pine Mixedwood/Shrub Rich (NW-V17) type, but the latter is characterized by an uneven-aged stand with considerable amounts of trembling aspen or white pine in the canopy. It is also similar to the Jack Pine/Ericaceous Shrub/Feathermoss (NW-V29) type, which can be distinguished by an almost continuous carpet of Schreber's feathermoss on the forest floor.
Soil & Ecosite Types: The Jack Pine/Low Shrub Vegetation Type (NW-V28) is usually found on Ecosite Types ES 13 (Jack Pine-Conifer, dry-moderately fresh, sandy soil) and ES 20 (Spruce-Pine/Feathermoss, fresh, sandy-coarse loamy soil). It occurs on rapidly drained, dry to fresh, 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.
