Description: This alliance is found in the extreme north-central United States and adjacent Canada. The tree layer is dominated by a moderately closed to closed canopy of mixed coniferous and deciduous species. ~Populus tremuloides$ is the only common deciduous tree, but scattered ~Betula papyrifera$ and ~Populus balsamifera$ are also found. ~Picea mariana$ is the most abundant coniferous species, and often the most abundant canopy species. ~Abies balsamea, Picea glauca$, and ~Pinus banksiana$ are typical associated conifers. The shrub layer is typically 1 m tall or less and ranges from open to dense. Species found in this layer include ~Diervilla lonicera, Ledum groenlandicum, Linnaea borealis, Rosa acicularis, Rubus pubescens, Vaccinium angustifolium$, and ~Vaccinium myrtilloides$. The herbaceous layer has great diversity. ~Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Cornus canadensis, Coptis trifolia, Maianthemum canadense, Petasites frigidus, Trientalis borealis$, and ~Viola renifolia$ are common herbaceous species. Mosses also cover a substantial portion of the forest floor. ^Stands of this alliance are found on flat to gently sloping sites with fresh to moist mineral soils. Soil texture is most often coarse loam, but can be clay, silt, or sand. Fine-textured soils tend to be on lacustrine substrates while coarse-textured soils result from morainal or glaciofluvial substrates. In Ontario, stands of this alliance often occur on calcareous soil.
