Northern Ontario Vegetation Type (V-type)


NE-V22: Black Spruce - Jack Pine - Feathermoss - Lichen

Summary: A conifer-dominated stand type with black spruce providing 11-20% cover in both the overstorey and understorey. Jack pine occurs less consistently, with 11-20% cover in the overstorey and 2-5% cover in the understorey of 1/3 to 2/3 of sample plots.

The low shrub layer is dominated by ericaceous shrubs, with sheep laurel and Labrador tea providing the most cover (11-20%), followed by lowbush and velvetleaf blueberries (each 6-10% cover). An herb layer is practically non-existent, with creeping snowberry (2-5% cover), listed as the only species.

The forest floor is composed of a carpet of feathermosses, with Schreber's feathermoss providing the most cover (>40%), and patches of coniferous litter. The common green peatmoss and northern peatmoss occur less consistently, forming colonies with 11-20% cover. Lichens are more common than in NE-V20 (Black Spruce-Jack Pine-Feathermoss), with the gray reindeer lichen providing 2-5% cover.

Soil and Ecosite Types: The Black Spruce-Jack Pine-Feathermoss-Lichen Vegetation Type (NE-V22) occurs on a variety of dry to fresh non-calcareous soil types, including very shallow soils over bedrock (SS3), dry to fresh sandy soils (S1), dry to fresh coarse loamy soils (S5), and fresh fine loamy to clayey soils (S13). The NE-V22 vegetation type may be found on ecosites ES 1p (Black Spruce-Jack Pine-Very Shallow Soil-Species Poor), ES 4 (Black Spruce-Jack Pine-Coarse Soil), and ES 5f (Black Spruce-Fine Soil).
