This is a semipermanently flooded community of brownwater rivers which occurs primarily in the outer Atlantic Coastal Plain extending through the East Gulf Coastal Plain. Vegetation is characterized by a dense canopy composed almost exclusively of straight, tall individuals of Taxodium distichum and Nyssa aquatica with a sparse to moderate subcanopy and depauperate shrub and herb layers. Occasional individuals of several species (e.g., Populus heterophylla, Salix nigra, Nyssa biflora, Planera aquatica, Ulmus americana, Fraxinus profunda, Fraxinus caroliniana, Carya aquatica, Quercus lyrata) are possible in the canopy or subcanopy. The herbaceous layer is very sparse, and typical species include Saururus cernuus, Proserpinaca pectinata, Proserpinaca palustris, Asclepias perennis, Commelina virginica, Leersia lenticularis, and Phanopyrum gymnocarpon (= Panicum gymnocarpon). It is found on the lower Atlantic Coastal Plain from southeastern Virginia to southern Georgia, and possibly on the lower Gulf Coastal Plain west to southeastern Louisiana, excluding the Mississippi River Alluvial Plain. It can be found in oxbow lakes and ponds, along the banks of rivers and lakes, on low wet flats and sloughs, swales and backswamps. It occurs only on saturated or flooded soils. Forests dominated by Taxodium distichum and Nyssa aquatica are common throughout the southeastern Coastal Plain. |

Deciduous high pocosin (actually mixed, but with a large and sometimes dominant component of deciduous shrubs). Stands are characterized by scattered <i>Pinus serotina</i> over dense deciduous and evergreen shrubs. Dominant shrubs include <i>Zenobia pulverulenta, Cyrilla racemiflora</i>, and <i>Lyonia lucida</i>. <i>Kalmia cuneata</i> is often present and sometimes abundant. |

This type covers seepage-fed herbaceous or shrub-herb wetlands of sandhills terrain found primarily in the Sandhills region but present in scarps and sand ridges elsewhere in the Coastal Plain of North Carolina and South Carolina. These are generally small areas on slopes, but can occur at slope bases where water is forced to the surface by a clay layer and soil conditions are permanently saturated. These communities are rare in the North Carolina Sandhills and on Fort Bragg and Camp MacKall, where they are usually found in high-moisture, open-canopied transitional areas located between streams (or impoundments) and seepage-fed slopes. The permanently saturated conditions of these sites most likely help to retard shrub and tree encroachment. Dominant species include <i>Sarracenia flava, Sphagnum</i> spp., <i>Carex exilis, Rhynchospora stenophylla, Danthonia epilis, Xyris fimbriata, Xyris chapmanii, Eupatorium resinosum</i>, and <i>Rhexia</i> spp. Sandhill seeps consist of a dense to open growth of various wetland shrubs and herbs, or mixtures of wetland and upland species, with structure determined by fire regime. Common shrubs include <i>Clethra alnifolia, Lyonia lucida, Photinia pyrifolia (= Aronia arbutifolia), Ilex glabra, Gaylussacia frondosa, Symplocos tinctoria, Morella caroliniensis (= Myrica heterophylla)</i>, and <i>Toxicodendron vernix</i>. A variety of other shrubs may be present in some sites. <i>Arundinaria gigantea ssp. tecta</i> may dominate in places, especially in frequently burned sites. <i>Osmunda cinnamomea</i> often dominates annually burned sites. Canopy species include <i>Pinus serotina, Pinus palustris</i>, and <i>Liquidambar styraciflua</i>. <i>Acer rubrum, Magnolia virginiana</i>, and <i>Persea palustris</i> are often present in the midstory. Herbs are sparse under shrub cover but may dominate frequently burned sites. Typical herbs include <i>Osmunda cinnamomea, Xyris caroliniana, Pteridium aquilinum, Woodwardia virginica, Dichanthelium</i> spp., <i>Andropogon glomeratus, Ctenium aromaticum, Sarracenia flava, Sarracenia purpurea, Sarracenia rubra, Drosera capillaris, Rhexia alifanus, Polygala lutea, Eupatorium pilosum</i>, and <i>Aristida stricta</i>. <i>Sphagnum</i> spp. are common. On frequently burned sites a great diversity of other herbs may also be present. Community structure is strongly controlled by fire regime. Because of their small size, Sandhill Seeps are subject to fires spreading from adjacent sandhill communities, and under natural fire regimes they probably burned more frequently than other similarly wet communities. At least parts of them burned almost as frequently as the adjoining sandhill communities. Under frequent fire Sandhill seeps are open and herb-dominated. In the absence of fire shrubs quickly expand and the vegetation becomes pocosin-like. The nutrient dynamics of these communities are not known. The presence of clay in the soil may allow greater retention of nutrients than in sandy soils, although the seepage is likely to be very low in nutrients. Like other small communities in sandhill areas, nutrients mobilized by fire may be available to Sandhill seeps even if they do not themselves burn. These communities are distinguished by the occurrence of wetland vegetation on seepage slopes. The boundary with Streamhead Pocosin may be difficult to determine in some areas. In infrequently burned areas where both are shrubby, Sandhill seeps may be recognized by partial or total isolation from a stream system, location on a sharp slope break, or by remnants of the herbaceous vegetation beneath the shrubs. Herb-dominated Sandhill seeps may be distinguished by their occurrence on relatively small, sloping, seepage-fed areas in sandhills. |

This type covers seepage-fed herbaceous or shrub-herb wetlands of sandhills terrain found primarily in the Sandhills region but present in scarps and sand ridges elsewhere in the Coastal Plain of North Carolina and South Carolina. These are generally small areas on slopes, but can occur at slope bases where water is forced to the surface by a clay layer. This type covers less wet types of Sandhill seeps which may be seasonally rather than permanently saturated and which may occur alone or as an outer zone to permanently saturated seeps. Sandhill seeps consist of a dense to open growth of various wetland shrubs and herbs, or mixtures of wetland and upland species, with structure determined by fire regime. Common shrubs include <i>Clethra alnifolia, Lyonia lucida, Photinia pyrifolia (= Aronia arbutifolia), Ilex glabra, Gaylussacia frondosa, Symplocos tinctoria, Morella caroliniensis (= Myrica heterophylla)</i>, and <i>Toxicodendron vernix</i>.

Herb-dominated Sandhill seeps may be distinguished by their occurrence on relatively small, sloping, seepage-fed areas in sandhills. This seep type is distinguished from the other wetter types by a drier flora that includes abundant <i>Aristida stricta</i> and <i>Pteridium aquilinum</i> and general lack of <i>Osmunda cinnamomea, Sarracenia flava, Calamovilfa brevipilis</i>, and other more water-loving plants. Typical shrubs are <i>Gaylussacia frondosa, Clethra alnifolia, Ilex glabra</i>, and <i>Arundinaria gigantea ssp. tecta</i>, with species such as <i>Lyonia lucida, Cyrilla racemiflora, Toxicodendron vernix</i>, and <i>Ilex coriacea</i> absent. |

This generally defined association covers seasonally flooded wetland depressions, often strongly dominated by <i>Woodwardia virginica</i>, which occur in acidic sands of the Coastal Plain. Vegetation is tall, up to 1.5 m in height. Additional associates include <i>Triadenum virginicum, Carex striata, Hypericum mutilum,</i> and <i>Decodon verticillatus</i>. Woody associates typically occur at the periphery of the pond, and may include scattered and stunted individuals of <i>Acer rubrum, Pinus taeda, Liquidambar styraciflua, Clethra alnifolia, Rhododendron viscosum</i>, or <i>Vaccinium corymbosum</i>. More information is needed on this vegetation type. It is attributed to various states in the Atlantic Coastal Plain from Delaware to Florida. |
