Reference:

Description:
This floodplain forest of the northeastern United States, primarily in the northern Piedmont, is a broadly defined successional or young version of medium-gradient river floodplain forest occurring on coarse alluvial substrates. The canopy is closed to somewhat open and usually dominated by <i>Platanus occidentalis</i>. <i>Populus deltoides, Acer saccharinum</i>, and <i>Ulmus americana</i> are usually present but not common; occasional associates include <i>Acer negundo, Fraxinus pennsylvanica, Juglans cinerea, Carya cordiformis, Celtis occidentalis, Acer saccharum</i>, and <i>Acer rubrum</i>. Shrubs or subcanopy are variable depending on geography and can include <i>Betula nigra, Carpinus caroliniana, Salix nigra, Lindera benzoin</i>, or <i>Alnus serrulata</i>, plus exotic invasives such as <i>Rosa multiflora, Berberis thunbergii</i>, and <i>Lonicera morrowii</i>. The herbaceous layer tends to be sparse to locally abundant and can include <i>Matteuccia struthiopteris, Osmunda cinnamomea, Onoclea sensibilis, Geum canadense, Impatiens pallida, Boehmeria cylindrica, Urtica dioica, Solidago rugosa, Hydrophyllum virginianum, Carex bromoides, Ageratina altissima</i>, plus vine species <i>Toxicodendron radicans</i> and <i>Parthenocissus quinquefolia</i>. There is typically a very high component of disturbance-tolerant exotic species such as <i>Lysimachia nummularia, Glechoma hederacea, Microstegium vimineum, Hesperis matronalis, Aegopodium podagraria, Polygonum cuspidatum</i>, and <i>Alliaria petiolata</i>.
