This shrubland is dominated by <i>Crataegus spathulata, Crataegus crus-galli, Crataegus berberifolia, Crataegus engelmannii, Berchemia scandens, Cornus drummondii, Diospyros virginiana, Juniperus virginiana var. virginiana, Ilex decidua, Sideroxylon lanuginosum ssp. lanuginosum, Prunus mexicana, Frangula caroliniana</i>, and <i>Rubus</i> spp. The tall-shrub stratum (2-5 m high) ranges from 25-60% cover. Open examples include a sparse to patchy ground cover. Grasses include <i>Schizachyrium scoparium, Andropogon glomeratus, Andropogon gerardii, Sporobolus</i> spp., <i>Setaria parviflora, Panicum flexile, Aristida</i> spp., <i>Paspalum floridanum</i>, and <i>Sorghastrum nutans</i>. This successional shrubland community develops on soils derived from marly clays and chalk of marine origin. These soils are typically silty clay loams, clays, and silt loams that are well-drained, slowly permeable, and alkaline (pH 7.5-8.0). Subsurface clay layers have calcareous concretions, weathered limestone aggregations and shrink-swell properties. This community typically occupies 1-8 hectares within calcareous forests dominated by <i>Pinus taeda</i> or <i>Quercus</i> spp. This community occurs in a nearly level to gently rolling landscape, on ridgetops and on gentle slopes that often border small streams. Moisture regimes are typically dry to dry-mesic. This community results from fire suppression of calcareous prairies but may also have occurred naturally in spatially or temporally fire-sheltered situations. It is associated with outcrops of the Cook Mountain Formation from western Winn Parish, west-central Louisiana and outcrops of the Fleming Formation in southeast Texas. |

This low-elevation seep is known from low elevations in the Southern Blue Ridge of North Carolina and Georgia, but is likely more widespread. The type may need substantial revision as more information is collected. This community occurs in stream headwaters and on the edges of small stream floodplains, where groundwater seepage emerges and provides a relatively constant flow and saturated conditions. A small streamlet (less than 1 m wide) flows through the community, and saturated and upland conditions form a mosaic through the remainder of the community. Physiognomy is variable, and may include herbaceous-dominated patches, shrubby areas, and areas with an open canopy of trees. The open to scattered canopy includes species such as <i>Betula lenta, Magnolia tripetala, Acer rubrum var. trilobum</i>, and <i>Nyssa sylvatica</i>. The shrub stratum is open to dense, and is dominated by <i>Alnus serrulata, Lyonia ligustrina, Kalmia latifolia, Lindera benzoin var. benzoin</i>, and <i>Vaccinium fuscatum</i>. Typical herbaceous species include <i>Scutellaria lateriflora, Thelypteris noveboracensis, Mimulus ringens, Osmunda cinnamomea, Ludwigia palustris, Apios americana, Oxypolis rigidior, Leersia virginica, Galium obtusum, Viola cucullata, Lycopus virginicus, Vernonia noveboracensis, Boehmeria cylindrica, Solidago canadensis, Impatiens capensis, Scirpus georgianus, Hypericum mutilum, Rhexia virginica, Ludwigia alternifolia, Solidago patula var. patula, Rudbeckia laciniata var. laciniata, Carex gynandra</i>, and <i>Juncus gymnocarpus</i>. |

This community includes non-alluvial wetland vegetation with a unique species composition, including both low mountain and Coastal Plain species, and occurring in low-elevation areas of the Southern Blue Ridge. It ranges from 500-700 m (1700-2400 feet) in elevation, on sites near streams that are generally flat to slightly sloping. These areas receive some seepage from adjacent slopes and are permanently saturated to intermittently dry. This community is found in the broad basin of the French Broad River in southern Buncombe, Henderson, and eastern Transylvania counties, North Carolina. It formerly occupied as much as 1000 acres, now reduced by drainage to a few altered remnants totaling less than 20 acres. The vegetation consists of a mosaic or zoned pattern of shrub thickets and herb-dominated areas, much of it underlain by <i>Sphagnum</i> mats. Trees may be scattered throughout or may dominate on the edges. Shrubs may include <i>Alnus serrulata, Rosa palustris, Salix sericea, Aronia arbutifolia, Myrica gale, Chamaedaphne calyculata, Gaylussacia dumosa, Rhododendron maximum, Rhododendron viscosum, Rhododendron arborescens, Viburnum nudum var. nudum, Viburnum nudum var. cassinoides, Kalmia latifolia, Kalmia carolina, Hypericum densiflorum, Lyonia ligustrina var. ligustrina, Ilex verticillata</i>, and <i>Menziesia pilosa</i>. The woody vine <i>Smilax laurifolia</i> is often present, climbing high into the shrubs and trees. The herb layer may include <i>Carex leptalea, Carex echinata, Carex folliculata, Carex gynandra, Carex collinsii, Scirpus cyperinus, Osmunda cinnamomea, Osmunda regalis var. spectabilis, Solidago patula var. patula, Packera aurea, Thelypteris palustris var. pubescens, Isoetes valida, Hypericum denticulatum, Juncus effusus, Juncus caesariensis, Drosera rotundifolia, Woodwardia virginica, Woodwardia areolata, Dulichium arundinaceum, Sarracenia purpurea, Sarracenia rubra ssp. jonesii, Eriophorum virginicum</i>, and <i>Parnassia asarifolia</i>. <i>Sphagnum</i> species include <i>Sphagnum palustre, Sphagnum affine, Sphagnum bartlettianum</i>, and <i>Sphagnum recurvum</i>. |

This association represents very small-scale and localized depressions or swales in extremely xeric sandhills in southeastern North Carolina. <i>Hypericum tenuifolium</i> dominates the shrub layer, while other scattered shrubs such as <i>Lyonia mariana</i> and <i>Gaylussacia dumosa</i> may be present. <i>Aristida stricta</i> and <i>Andropogon</i> spp. are the dominant herbs. In this landscape, <i>Aristida stricta</i> is restricted to this community, apparently because of the extremely xeric conditions of the surrounding sandhill community [see ~<i>Pinus palustris / Quercus laevis - Quercus geminata / Rhynchospora megalocarpa</i> Woodland (CEGL003590)$$]. |

This association is one of several documented types of shortleaf pine - hardwood forests in the Upper East Gulf Coastal Plain. Stands are dominated by <i>Pinus echinata</i>, often with a significant hardwood component. The most characteristic hardwood, often the second most important overstory tree, is <i>Quercus falcata</i>. Other tree species may also be encountered in typical stands of this type, but they are generally lacking from the overstory or found only in limited abundance. Some stands may have <i>Quercus montana</i> as a component. A number of subcanopy, shrub, and herbaceous species may also be present; the specific floristic composition may vary among stands based on a number of factors. This type should be compared to other <i>Pinus echinata</i> communities of the region; stands with high cover values of white oak are generally accommodated by ~<i>Pinus echinata - Quercus alba - Carya tomentosa</i> East Gulf Coastal Plain Forest (CEGL004050)$$. Stands of this association are subject to frequent prescribed burning on the Tombigbee National Forest (Mississippi), and many are managed for red-cockaded woodpecker (<i>Picoides borealis</i>) on the adjacent Noxubee National Wildlife Refuge. |

This <i>Pinus echinata - Quercus stellata</i> community occurs on dry, acidic, loamy to clayey uplands in the Upper East Gulf Coastal Plain of Mississippi, and possibly elsewhere in the region. The dominant trees are <i>Pinus echinata</i> and <i>Quercus stellata</i>. In natural, or well-burned condition, few other tree species are present. The understory tends to be quite open and herb-dominated, and may be quite species-rich. |

This forest, dominated by <i>Fagus grandifolia</i> and <i>Quercus</i> spp., occurs on deep loess soils in the Gulf Coastal Plain region of Arkansas, northern Mississippi, western Tennessee, and western Kentucky. Examples are diverse mesic hardwood forests found on southern Crowley's Ridge (Arkansas) and related loess bluffs east of the Mississippi River. These forests have a rich species composition of mesic flora, including some species restricted, or nearly so, to this habitat in the region. <i>Fagus grandifolia</i> and <i>Quercus alba</i> and/or <i>Quercus rubra</i> may be the most important species in the canopy, although <i>Fagus</i> is often the single most dominant tree (other locally mesic stands dominated by oaks rather than <i>Fagus</i> would be accommodated by ~<i>Quercus (rubra, alba, velutina) / Acer floridanum / Asimina triloba</i> Forest (CEGL004069)$$). The presence of <i>Quercus rubra</i> is an important component of these stands and helps to distinguish this association from related types (generally found south of this type) that support only <i>Quercus alba</i>. Stands support a variety of other species indicative of rich mesic conditions, including <i>Acer floridanum, Ostrya virginiana, Asimina triloba, Arundinaria gigantea</i>, and <i>Cynoglossum virginianum</i>. Related forests of more southerly loess bluffs occur within the range of <i>Magnolia grandiflora</i> [see ~<i>Quercus pagoda - Magnolia grandiflora - Fagus grandifolia / Hydrangea quercifolia / Thelypteris kunthii</i> Forest (CEGL007461)$$]. |

These dwarf-shrub/herbaceous openings form a mosaic with ~<i>Ilex glabra - Lyonia lucida - Zenobia pulverulenta</i> Wet Shrubland (CEGL003944)$$ in the wettest low pocosins of peat domes (ombrotrophic blanket bogs) of the Outer Coastal Plain of North Carolina. They are dominated by <i>Chamaedaphne calyculata</i> with <i>Carex striata</i> and <i>Woodwardia areolata</i> common in the herbaceous layer. Characteristic species include <i>Vaccinium macrocarpon, Rhynchospora alba, Polygala brevifolia</i>, and <i>Chamaedaphne calyculata</i>. This type is distinguished by having greater than 25% cover by <i>Vaccinium macrocarpon</i>. |
