CEGL007731 Populus deltoides / Acer negundo / Boehmeria cylindrica Floodplain Forest
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Eastern Cottonwood / Box-elder / Small-spike False Nettle Floodplain Forest
Colloquial Name: Atlantic Coastal Plain Cottonwood Levee Forest
Hierarchy Level: Association
Type Concept: This forest occurs on well-drained loamy soils of levees in the coastal plains of the southeastern United States. The fairly open to mostly closed canopy of this community is dominated by Populus deltoides. This forest type is documented in the Mid-Atlantic Coastal Plain but is present, or assumed to be present, in adjacent coastal plain regions; global distribution needs assessment. The well-developed subcanopy is dominated by Acer saccharinum and Acer negundo. Fraxinus pennsylvanica, Planera aquatica, Celtis laevigata, Ulmus americana, and likely other species may be present in the canopy and subcanopy strata as well. The shrub layer is very sparse and is composed of canopy and subcanopy species in addition to Asimina triloba, Ilex decidua, and likely other species. The sparse herbaceous layer is also low in species richness. Among the species that may be present are Chasmanthium latifolium, Pilea pumila, Leersia lenticularis, Carex grayi, Elymus virginicus, Carex bromoides, Matelea carolinensis, Sanicula canadensis, Cryptotaenia canadensis, Boehmeria cylindrica, Erechtites hieraciifolius, Justicia ovata, and others. Vine coverage is sparse as well, and among the species that may be present are Toxicodendron radicans, Parthenocissus quinquefolia, Smilax tamnoides, Bignonia capreolata, Vitis rotundifolia, and Mikania scandens.
