Description:
This forest alliance, found from the western Great Lakes to southern Manitoba, occurs on relatively recently disturbed dry-mesic sites. The tree canopy is typically continuous and composed of a mix of coniferous and deciduous species. Although the mix of evergreen and deciduous trees varies, conifers are usually taller than the deciduous trees. ~Acer rubrum, Betula papyrifera, Pinus strobus, Pinus resinosa, Populus tremuloides, Populus grandidentata$, and ~Quercus rubra$ are all common canopy species. ~Abies balsamea, Acer saccharum, Picea glauca$, and ~Thuja occidentalis$ can occur in the overstory but are more abundant as saplings. The tall-shrub layer is moderately dense, but low shrubs are infrequent. Species in these layers include ~Acer spicatum, Corylus cornuta, Diervilla lonicera$, and ~Lonicera canadensis$. The herbaceous layer is poorly to moderately well-developed. It contains species such as ~Aralia nudicaulis, Eurybia macrophylla (= Aster macrophyllus), Clintonia borealis, Cornus canadensis, Linnaea borealis, Maianthemum canadense, Streptopus lanceolatus var. longipes (= Streptopus roseus)$, and ~Trientalis borealis$. Mosses, such as ~Dicranum polysetum$ and ~Pleurozium schreberi$, are common in Canada. ^This alliance is found on flat to rolling topography on outwash plains and moraines. Soils are often well-drained sands or sandy loams, but can be loam or silt. They range from moderately infertile to moderately fertile.
