Acer saccharinum Temporarily Flooded Forest Alliance

This alliance contains floodplain forests of major rivers in the eastern United States where Acer saccharinum is generally dominant. Other tree associates include Platanus occidentalis, Celtis laevigata, Carya illinoinensis, Ulmus americana, Acer negundo, Fraxinus pennsylvanica, Ulmus rubra, Salix nigra, Betula nigra, and Populus deltoides. Common shrub species include Lindera benzoin, Ilex decidua, Asimina triloba, Cephalanthus occidentalis, Alnus serrulata, and Forestiera acuminata (in the Southeast). Characteristic herbs include nettles and ferns, such as Boehmeria cylindrica, Urtica dioica, Laportea canadensis, Onoclea sensibilis, and Matteuccia struthiopteris, and in the South, Leersia lenticularis, Pilea pumila, Carex grayi, Impatiens capensis, and others. Forests in this alliance generally occur on well-drained, sandy soils, on infrequently flooded bottomlands, on levees, and on deep silts on stabilized sites along larger rivers. They also may occur along smaller rivers but are most common along bigger rivers where there is more scour and more silt deposition. This alliance is common in the Interior Low Plateau and in the Upper West Gulf Coastal Plain particularly along the White and Arkansas rivers north to the Ozarks, and then in the central Midwest to Wisconsin and Minnesota, and the East Coast to Maine. It is sparingly distributed in the Piedmont and is known from the South Atlantic Coastal Plain in South Carolina. |

This West Gulf Coastal Plain forest is known only from mesic to moist calcareous soils associated with the Jackson Geologic Formation in north-central Louisiana. It is characterized by a dense canopy, 20-30 m tall, of Quercus oglethorpensis, Quercus similis, Quercus sinuata var. sinuata, Quercus phellos, Quercus pagoda, Quercus shumardii, Quercus alba, Pinus taeda, Carya ovata, Acer barbatum, Liquidambar styraciflua, Fraxinus americana, and Ulmus alata. A sparse subcanopy of canopy species and a sparse shrub layer of Crataegus marshallii, Crataegus flava, Crataegus triflora, Aesculus pavia var. pavia, Bignonia capreolata, and Parthenocissus quinquefolia are present. The sparse to moderately dense herb layer is comprised of Trillium ludovicianum, Oxalis rubra, Carex cherokeensis, Sisyrinchium sp., Tillandsia usneoides, Pleopeltis polypodioides ssp. michauxiana, Chasmanthium sessiliflorum, Danthonia spicata, Lithospermum tuberosum, Allium canadense var. canadense, and Cardamine bulbosa. Characteristic examples of this type are known from Copenhagen Forest (Caldwell Parish, Louisiana). |

Carex striata var. brevis Herbaceous Vegetation

This vegetation occupies Coastal Plain depression meadows around the perimeter of Coastal Plain ponds and is dominated by Carex striata var. brevis (= Carex walteriana var. brevis). Examples include vegetation on the outer margins of Coastal Plain pond shores in New York, Maryland and Delaware or in localized swales in the New Jersey pine barrens. The substrate is typically composed of sand and gravel but some community types may occur on organic muck. Carex striata usually occurs in dense stands with few other associates, which may include seedlings of Cephalanthus occidentalis and Acer rubrum, as well as Cladium mariscoides, Rhexia virginica, Bidens frondosa, Rhynchospora macrostachya, Rhynchospora chalarocephala, Fimbristylis autumnalis, Juncus canadensis, Dulichium arundinaceum, Hypericum mutilum, and Panicum hemitomon. Sphagnum is often abundant. |
