Name:
Pinus strobus - (Pinus resinosa) - Populus tremuloides Forest Alliance
Reference:
Midwestern Ecology Working Group...
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.
