Reference: EcoArt 2002
Description: This alliance, found in the extreme north-central United States and adjacent Canada, is composed of a mix of coniferous and deciduous trees, with the conifers tending to be more abundant in the north. The canopy is typically dominated by ~Pinus banksiana$ and ~Populus tremuloides$ with lesser amounts of ~Abies balsamea, Betula papyrifera, Picea glauca$, and ~Picea mariana$. Tree density and crown spacing may be moderately dense to dense, but sufficient light penetrates to permit the growth of a vigorous shrub layer. Most shrubs are less than 1 m tall. The most common among these are ~Corylus cornuta, Diervilla lonicera, Linnaea borealis, Rosa acicularis, Rubus pubescens$, and ~Vaccinium$ spp. The herbaceous layer is also typically quite rich with species such as ~Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Cornus canadensis, Clintonia borealis, Streptopus lanceolatus var. longipes (= Streptopus roseus), Trientalis borealis$, and ~Viola$ spp. ^This alliance is found on generally level sandy outwash plains or moderately sloping moraines. The soils are fresh to dry, deep, sandy loams, loams, and fine sands. In Manitoba, the soils tend to be somewhat more moist and finer.
