Description:
This alliance is composed of rich, mesic forests of the east-central United States and southern Canada. The southern range of this alliance is limited by the distribution of ~Acer saccharum$ which is largely absent from the Coastal Plain. The forest canopy and subcanopy are typically dominated by ~Acer saccharum$ and ~Fagus grandifolia$, although ~Liriodendron tulipifera$ may be an important canopy component in some parts of the range. Other common trees include ~Carpinus caroliniana, Carya$ spp., ~Fraxinus americana, Ostrya virginiana, Quercus rubra, Tilia americana$, and ~Ulmus americana$. In the southern part of this alliance's range, additional species may include ~Quercus alba, Tilia americana, Liquidambar styraciflua, Aesculus glabra, Nyssa sylvatica$, and ~Carya cordiformis$. Shrubs are usually rare in northern stands but become more abundant in southern stands. ~Asimina triloba$ and ~Lindera benzoin$ (in the southern parts of this alliance's range), ~Diervilla lonicera, Euonymus obovata$, and ~Sambucus$ spp. (in the northern parts), ~Morus rubra$, and ~Corylus americana$ are typical shrubs. The herbaceous layer is well-developed. The most abundant species include ~Adiantum pedatum, Arisaema triphyllum, Claytonia virginica, Dicentra canadensis, Dryopteris intermedia, Galium aparine, Maianthemum canadense$ (in the north), ~Maianthemum racemosum, Menispermum canadense, Osmorhiza claytonii, Phegopteris hexagonoptera$ (in the south), ~Podophyllum peltatum, Polygonatum biflorum, Sanguinaria canadensis, Trillium grandiflorum$, and ~Viola$ spp. ^Stands of this alliance are found on flat, rolling, or, in the south, dissected topography. South of the limit of glaciation there is an increasing tendency for this alliance to be found on north- or east-facing slopes. The soils are fertile well-drained, silt, silt loam, sandy loam, or loam. Those in the north have formed over glacial till almost exclusively, while stands south of the limit of Wisconsin glaciation may form from till, alluvium, sandstone, or shale.
