Description:
This is a tall-shrub swamp of seasonally flooded basins in the eastern United States. It occurs in small open basins, closed sandplain basins, and seasonally flooded zones within larger wetlands. It may also form as a result of beaver activity. This vegetation can occur on the margins of Coastal Plain ponds. This community is influenced by a strongly fluctuating water table with flooded conditions in spring and early summer followed by a drop in the water table below soil surface usually by late summer. There is usually a shallow organic layer often over sand. Dominant shrubs include <i>Vaccinium corymbosum, Ilex verticillata</i>, and <i>Rhododendron viscosum</i>. Scattered <i>Acer rubrum</i> are not uncommon. <i>Lyonia ligustrina</i> and <i>Cephalanthus occidentalis</i> are characteristic although not necessarily dominant. Associated shrub species may include <i>Clethra alnifolia, Spiraea tomentosa, Chamaedaphne calyculata, Ilex glabra, Leucothoe racemosa, Decodon verticillatus, Kalmia angustifolia, Alnus serrulata, Myrica gale</i>, and <i>Aronia</i> spp. Herbaceous composition is variable; some of the more typical species include <i>Osmunda cinnamomea, Osmunda regalis, Thelypteris palustris, Onoclea sensibilis, Calla palustris, Lycopus uniflorus, Triadenum virginicum, Glyceria striata, Leersia oryzoides, Dulichium arundinaceum, Juncus effusus</i>, and <i>Woodwardia virginica</i>. A layer of peatmoss is common and varies in cover; species include <i>Sphagnum fimbriatum, Sphagnum rubellum, Sphagnum magellanicum, Sphagnum fallax</i>, and <i>Sphagnum viridum</i>.
