Description:
This alliance, found in the northeastern United States and southern Canada, is broadly defined and contains a number of communities generally known as 'rich forests,' 'mixed mesophytic forests,' and 'rich northern hardwood forests.' The tree canopy of these forests is variable, but ~Acer saccharum, Fraxinus americana$, and ~Tilia americana$ are almost always present. Associated canopy trees include ~Quercus rubra, Ostrya virginiana, Ulmus rubra, Acer rubrum, Betula alleghaniensis, Fagus grandifolia, Juglans nigra, Liriodendron tulipifera, Magnolia acuminata$, and ~Prunus serotina var. serotina$. The shrub layer is variable in cover and includes ~Cornus alternifolia, Hamamelis virginiana, Lonicera canadensis, Rhododendron periclymenoides (= Rhododendron nudiflorum), Staphylea trifolia$, and ~Viburnum acerifolium$. The herbs include ~Cardamine$ (subgen. ~Dentaria$) spp., ~Hepatica nobilis var. obtusa, Hydrophyllum virginianum, Elymus hystrix, Osmorhiza$ spp., ~Trillium grandiflorum, Viola$ spp., and others. Stands of this alliance occur on flat to rolling topography, and some stands may be on steep slopes. Soils are usually deep, moderately to well-drained sands, loams, silt loams, moderately acid to moderately alkaline, and of high fertility, often derived from calcareous parent materials. Soil moisture holding and cation exchange capabilities are high.
