Semipermanently to permanently flooded ponds or pools are uncommon natural features of major Coastal Plain and Piedmont floodplains. These wetlands are typically developed in abandoned oxbows and cut-off meanders, ranging in size from less than 0.01 ha to about four ha (0.2 to 10 ac). Community composition is probably influenced by a combination of environmental factors, including flooding regime, water depths, soil fertility, and degree of shading. Dominant vegetation varies from woodlands and shrublands in shallower, semipermanently flooded ponds to submerged or floating aquatics in deeper ponds. Scattered bald cypress (Taxodium distichum), tupelos (Nyssa aquatica and Nyssa biflora), green ash (Fraxinus pennsylvanica), or red maple (Acer rubrum) are sometimes rooted in large Coastal Plain oxbow ponds. More often, shrublands dominated by buttonbush (Cephalanthus occidentalis) or swamp loosestrife (Decodon verticillatus), or non-tidal marshes dominated by arrow-arum (Peltandra virginica), smartweeds (Persicaria spp.), and swamp rose-mallow (Hibiscus moscheutos), are established. In the more deeply flooded ponds, aquatic species prevail, with or without scattered shrubs and emergents such as Virginia chain fern (Woodwardia virginica), sedges (Carex spp.), and eastern mannagrass (Glyceria septentrionalis). Typical aquatics include common mermaid-weed (Proserpinaca palustris), bladderworts (Utricularia spp.), common spatterdock (Nuphar advena), duckweeds (Lemna spp.), duckmeal (Spirodela spp.), large water-starwort (Callitriche heterophylla var. heterophylla), water shield (Brasenia schreberi), hornworts (Ceratophyllum spp.), waterweeds (Elodea spp.), American frog's-bit (Limnobium spongia), pondweeds (Potamogeton spp.), eastern mosquito fern (Azolla caroliniana), milfoils (Myriophyllum spp.), and shade mudflower (Micranthemum umbrosum).
