Northern Ontario Vegetation Type (V-type)
Summary: A wet, conifer stand with black spruce dominant in the overstorey (21-40% cover); larch and balsam fir may also occur in the overstorey, but cover values were insignificant. Regeneration of black spruce and balsam fir each provide 6-10% cover in the understorey.
The shrub layer is dominated by speckled alder, providing 11-20% cover in the tall shrub layer, and ericaceous shrubs in the low shrub layer, including Labrador tea (6-10% cover), lowbush and velvetleaf blueberries (2-5% cover), and less consistently, sheep laurel, also with 2-5% cover.
The herb layer is moderately poor, with sedges, creeping snowberry, and goldthread providing the most cover (2-5%). The characteristic boreal forest species occur with less frequency than the previous species, except for bunchberry, which also provides 2-5% cover. Woodland horsetail provided 2-5% cover in 1/3 to 2/3 of sample plots, with 2-5% cover. The forest floor is dominated by a carpet of feathermosses, in slightly drier areas, and Sphagnum species in slightly wetter areas. The dominant feathermoss species include Schreber's feathermoss (21-40% cover), plume moss, and stairstep moss, along with Dicranum mosses (each 2-5% cover). Sphagnum species include common green peatmoss (21-40% cover), midway peatmoss (11-20% cover), and northern peatmoss (6-10% cover). Wulf's peatmoss, often found around the base of tree trunks, provides 2-5% cover.
Soil and Ecosite Types: The Black Spruce-Speckled Alder-Labrador Tea-Sphagnum Vegetation Type (NE-V24) occurs on wet, deep organic soils (S17, S18). The NE-V24 vegetation type is most commonly found on ecosite types ES 12 (Black Spruce-Larch-Labrador Tea-Organic soil) and ES 9p (Black Spruce-Larch-Moist Soil-Species Poor), but may also occur on types ES 5f (Black Spruce-Fine Soil), ES 8 (Black Spruce-Feathermoss-Sphagnum-Moist Soil), ES 13p (Black Spruce-Larch-Speckled Alder-Organic Soil-Species Poor), and ES 11 (Black Spruce-Labrador Tea-Organic Soil).
