This aquatic vegetation, dominated by the invasive alien plant <i>Hydrilla verticillata</i>, is found in natural lakes and anthropogenic impoundments. Stands of this ruderal vegetation are dominated by <i>Hydrilla verticillata</i> often to the exclusion of all other species. Since its introduction, this plant species has rapidly spread across the southeastern United States. Its spread into anthropogenic impoundment lakes is exacerbated by the transport of propagules on boat propellers. It produces vegetative propagules known as turions, which can resist desiccation for long periods of time. |

This forest association of the West Gulf Coastal Plain and Upper West Gulf Coastal Plain ecoregions is codominated by <i>Pinus echinata</i> and <i>Pinus taeda</i> with some combination of the nominal oaks <i>Quercus alba, Quercus falcata</i>, and <i>Quercus stellata</i>. Examples tend to occur on slopes, and generally occupy sites of intermediate moisture status, being somewhat drier than typical <i>Pinus taeda</i> communities, and somewhat more mesic than typical <i>Pinus echinata</i> or <i>Pinus palustris</i> communities. Stands assigned to this type should have near-equal proportions of at least two of the nominal oak species; stands which are more obviously dominated by a single species are covered by other associations. These are apparently natural forests that may occur both within and beyond (landward and north of) the range of <i>Pinus palustris</i>. |

This association is a seasonally flooded herbaceous wetland dominated by <i>Carex hyalinolepis</i>. Other species present (in small amounts) include <i>Rumex verticillatus, Ipomoea sagittata</i>, and <i>Cyperus</i> spp. This association occurs in seasonally flooded depressions in sea islands of South Carolina. The water is fresh, but receives salt water in hurricane events. |

This association is apparently a "high subtype" of blackwater bottomland hardwood-pine forest of the sandhills of the Atlantic Coastal Plain of North Carolina, South Carolina, Georgia, and possibly other states. The canopy would be expected to be dominated by <i>Pinus taeda</i> and <i>Quercus laurifolia</i>, with an understory characterized by <i>Vaccinium elliottii</i> and <i>Arundinaria gigantea</i>. More detailed information is needed. |

This high-elevation grassland of the Appalachian Mountains results from clearing and pasturing of montane forests. These communities typically occur above 1100 m (3600 feet) and are known in Virginia from the Laurel Fork area of Highland County (Allegheny and Middle mountains; Warm Springs Ranger District) and Wilburn Ridge area of Grayson County (Mount Rogers National Recreation Area). <i>Danthonia spicata</i>, or mixtures of <i>Danthonia spicata</i> and <i>Danthonia compressa</i>, typically dominate. Associates include <i>Solidago rugosa ssp. aspera, Dennstaedtia punctilobula, Dichanthelium</i> spp., <i>Pteridium aquilinum var. latiusculum, Fragaria virginiana, Hieracium</i> spp., <i>Potentilla</i> spp., and <i>Rumex acetosella</i>. |

These forests occur in seepage areas in pine-dominated uplands of the East Gulf Coastal Plain of Florida, Georgia, Alabama and Mississippi (and possibly Louisiana). The tree canopy is variable with <i>Liriodendron tulipifera, Nyssa biflora</i>, and <i>Magnolia virginiana</i> typically dominant, but <i>Liquidambar styraciflua, Pinus taeda</i>, and <i>Acer rubrum</i> may be codominant in some examples. Canopy cover in these seeps is not complete, and the shrub and herbaceous layers are well-developed. The shrub and subcanopy are dominated by <i>Morella caroliniensis, Toxicodendron vernix, Persea palustris</i>, and <i>Magnolia virginiana</i>; with <i>Chionanthus virginicus, Aronia arbutifolia, Viburnum nudum, Ilex coriacea, Clethra alnifolia, Cephalanthus occidentalis, Rhododendron canescens, Vaccinium elliottii</i>, and other species present. The herbaceous layer includes <i>Osmunda regalis, Osmunda cinnamomea, Woodwardia areolata, Apios americana, Botrychium dissectum, Chasmanthium sessiliflorum, Eupatorium rotundifolium, Platanthera ciliaris, Mitchella repens, Dioscorea villosa, Sphagnum</i> spp., and other species. Woody vines are common, and species that occur are <i>Smilax walteri, Smilax laurifolia, Smilax glauca, Smilax rotundifolia, Berchemia scandens</i>, and others. |

This seasonally saturated longleaf pine - pond pine - loblolly pine woodland is restricted to the wiregrass gap region of South Carolina. The open canopy of this association is dominated by a combination of <i>Pinus palustris</i> and <i>Pinus serotina</i>. This is a placeholder pending further analysis. |

This pine flatwoods community occurs in eastern Georgia. The open (to fairly closed) canopy is characterized by <i>Pinus palustris</i>, although <i>Pinus elliottii var. elliottii</i> can be present as well. Depending on fire regime, the ground layer can be shrub-dominated or herb-dominated, but composition does not change greatly. Typical shrubs include <i>Ilex glabra, Gaylussacia tomentosa, Morella cerifera, Serenoa repens, Aronia arbutifolia, Gaylussacia dumosa, Kalmia hirsuta</i>, and <i>Vaccinium myrtilloides</i>. The grass layer is typically dominated by mixtures of <i>Sporobolus pinetorum</i>, sometimes with admixtures of <i>Sporobolus curtissii, Ctenium aromaticum</i>, or <i>Aristida beyrichiana</i>. Other characteristic species include <i>Andropogon glaucopsis, Andropogon glomeratus var. hirsutior, Aristida spiciformis, Oclemena reticulata, Balduina uniflora, Bigelowia nudata ssp. nudata, Carphephorus paniculatus, Carphephorus tomentosus, Centella erecta, Cleistes</i> sp., <i>Coreopsis linifolia, Eupatorium leucolepis, Euthamia caroliniana, Hypericum gymnanthum, Lycopodiella alopecuroides, Pogonia ophioglossoides, Polygala lutea, Rhexia alifanus, Rhexia lutea, Rhynchospora baldwinii, Rhynchospora ciliaris, Sarracenia flava, Sarracenia minor, Syngonanthus flavidulus, Xyris baldwiniana</i>, and <i>Xyris caroliniana</i>. |

This community is found in northwestern Ohio and possibly in northeastern Indiana and Ontario, where it is found on mineral/peaty soils, and in a disjunct stand in New Jersey. Stands contain <i>Cladium mariscoides, Carex cryptolepis, Juncus canadensis</i>, and <i>Rhynchospora alba</i>. Further characterization is needed. Few sites are known, the largest from Springville Marsh (in Seneca County near the border with Wyandot) is fairly degraded. It was thought to have been a complex of fen, wet meadow and tallgrass prairie, and was over 30 miles long and a few miles wide. Currently, there are at least 8-10 small meadow/fen openings. They are under serious threat from invasive species such as <i>Typha angustifolia</i>, and from woody species such as <i>Cornus amomum</i>. The site may also suffer from a drop in water table due to adjacent agriculture. The New Jersey site occurs in a lake basin and is characterized by <i>Cladium mariscoides, Schoenoplectus acutus, Thelypteris palustris, Proserpinaca palustris</i>, and <i>Juncus canadensis</i>, with low cover of other herbs, including <i>Carex cryptolepis, Eleocharis elliptica, Lobelia kalmii</i>, and others. |

This wetland association is reported from Utah and Ontario, Canada, but its distribution is much broader. If its range is similar to the ranges of dominant and diagnostic species, then it likely occurs throughout much of northern and western North America. Sites include streambanks, wet meadows and ditches. Substrates are generally organic alluvium. This community is typically flooded much of the growing season. The water table is high even when surface water is gone. The vegetation is characterized by the moderately dense to dense herbaceous layer that is dominated or codominated by <i>Equisetum arvense</i> or <i>Equisetum variegatum</i>. Other wetland and facultative wetland plants may be present in low cover, but the dominance of <i>Equisetum</i> spp. is diagnostic of this type. Introduced graminoids such as the perennial <i>Poa pratensis</i> or the annual <i>Bromus diandrus</i> are known to codominate some stands. |
