Name:
Acer saccharum - Tilia americana - Fraxinus americana Forest Alliance
Reference:
NatureServe Biotics 2019
Description:
These are generally known as "rich forests" and "rich northern hardwood forests." The tree canopy of these forests is variable, but <i>Acer saccharum, Betula alleghaniensis, Fraxinus americana, Populus tremuloides</i> (in the Great Lakes), and <i>Tilia americana</i> are almost always present. Associated canopy trees often include <i>Acer spicatum, Betula lenta, Fagus grandifolia, Ostrya virginiana</i>, and <i>Prunus serotina var. serotina</i>. The shrub layer is variable in cover depending on site characteristics and canopy density. Common species include <i>Cornus alternifolia, Corylus americana, Dirca palustris, Hamamelis virginiana, Lonicera canadensis, Sambucus racemosa, Viburnum acerifolium</i>, and <i>Viburnum lantanoides</i>. Typical herbs include <i>Adiantum pedatum, Arisaema triphyllum, Asarum canadense, Cardamine</i> spp., <i>Carex platyphylla, Caulophyllum thalictroides, Osmorhiza</i> spp., <i>Sanguinaria canadensis, Solidago flexicaulis, Trillium grandiflorum</i>, and <i>Viola</i> spp. This alliance is found in the northern Great Lakes, northeastern United States and southern Canada. Stands of this alliance occur in a variety of settings, including gentle to steep slopes, boulder talus, or in valleys adjacent to floodplains. Soils are usually deep, moderately to well-drained sands, loams, silt loams, moderately acidic to moderately alkaline, and of high fertility, often derived from calcareous parent materials. Soil moisture-holding and cation-exchange capabilities are high.
