Name: Acer saccharinum - Acer negundo / Ageratina altissima - Laportea canadensis - (Elymus virginicus) Forest
Reference:
Description: This is a forested community of large river floodplains in the Mid-Atlantic states of Maryland, Virginia, West Virginia, and Pennsylvania. These forests occupy banks and first bottoms of major rivers with nutrient-rich silt loams, sand loams, and sands that are temporarily inundated, annually or less often, in major flood events. Canopies are closed and dominated by <i>Acer saccharinum</i>, with <i>Acer negundo</i> dominating a subcanopy layer. Other minor overstory and understory associates include <i>Populus deltoides, Celtis occidentalis, Fraxinus pennsylvanica, Ulmus americana</i>, and <i>Juglans nigra</i>. The shrub layer ranges from sparse to dense but is usually dominated by <i>Lindera benzoin</i>. Characteristic species of the herb layer are <i>Ageratina altissima, Laportea canadensis, Impatiens pallida, Viola sororia, Leersia virginica, Verbesina alternifolia, Urtica dioica ssp. dioica, Elymus virginicus, Elymus riparius, Geum canadense, Pilea pumila, Rudbeckia laciniata</i>, and <i>Cryptotaenia canadensis</i>. Vines of <i>Toxicodendron radicans</i> and <i>Parthenocissus quinquefolia</i> are common. Early-successional stands are usually strongly dominated by even-aged <i>Acer saccharinum</i>.
