This community is characterized by a 10- to 14-m canopy of Pinus palustris and Pinus echinata patchily distributed over low shrubs, grasses, and forbs, with small, scattered rocky outcrops of serpentine in the Piedmont of Georgia. Quercus marilandica is common in the subcanopy. Common herbs and vines include Schizachyrium scoparium var. scoparium, Baptisia alba, Chrysopsis mariana, Centrosema virginianum, Gelsemium sempervirens, and Manfreda virginica. This community occurs on upper slopes and ridgetops over dry, rocky soils. Soils are classified as Alfisols and are derived from serpentine parent material. This community grades into woodlands dominated by Quercus marilandica on the surrounding lower slopes. |

This pine dune forest type is found on dune systems on Lake Michigan and Lake Huron in the United States and possibly in Canada. The canopy is more-or-less closed, and is dominated by Pinus banksiana, Pinus resinosa, and Pinus strobus. This type has not been well described, and further characterization is needed. |

The canopy of stands of this association is dominated by Betula nigra, Liquidambar styraciflua, Platanus occidentalis, Quercus nigra, Quercus pagoda, Ulmus americana, and Carya glabra. The midstory is dominated by Carpinus caroliniana, Ulmus alata, Halesia diptera, Ilex opaca var. opaca, and Ostrya virginiana. Understory shrubs include Vaccinium elliottii, Asimina triloba, Callicarpa americana, and patchy Arundinaria gigantea. Woody vines include Smilax rotundifolia and Vitis rotundifolia. Herbs include Elephantopus carolinianus, Onoclea sensibilis, Polystichum acrostichoides, Dichanthelium spp., Panicum spp., Carex spp., and Chasmanthium latifolium or Chasmanthium laxum, either one of which may have high cover values. These forests occur on narrow floodplains along medium-sized streams in the West Gulf Coastal Plain. |

Panicum hemitomon - Dulichium arundinaceum Herbaceous Vegetation

This association includes emergent zones of Eastern Highland Rim ponds in southeastern middle Tennessee (Coffee and some adjoining counties) dominated by <i>Panicum hemitomon</i>. Ponds dominated by maidencane are rare in this region as the species is primarily found in the Coastal Plain. This community is typically found in small, open, wet depressions in upland flats, sometimes associated with headwaters of creeks. It may form a mosaic with other upland pond vegetation, for example, ~<i>Cephalanthus occidentalis / Hibiscus moscheutos</i> ssp. <i>moscheutos</i> Depression Pond Shrubland (CEGL004742)$$ or vegetation of the ~<i>Scirpus cyperinus</i> Wet Meadow Herbaceous Alliance (A1386)$$. <i>Panicum hemitomon</i> is the dominant species. Small scattered trees and shrubs may be present, such as <i>Cephalanthus occidentalis, Quercus phellos, Liquidambar styraciflua</i>, and <i>Hibiscus moscheutos</i>. Associated herbs include <i>Polygonum hydropiperoides, Saccharum baldwinii, Dulichium arundinaceum, Proserpinaca pectinata, Carex bullata, Carex gigantea, Juncus repens, Leersia hexandra, Dichanthelium longiligulatum</i>, and <i>Typha latifolia</i>. Several other disjunct Coastal Plain species occur at known examples (for example <i>Xyris laxifolia var. iridifolia, Lachnanthes caroliana</i>). |

Schizachyrium scoparium - Andropogon (gyrans, ternarius, virginicus) Herbaceous Vegetation

This mixed-grass association represents a variety of essentially native perennial grasslands which are (or have been) human-maintained to some extent and which contain a variable mix of <i>Schizachyrium scoparium</i> with <i>Andropogon</i> spp. It may occur on annually mowed powerline rights-of-way, mowed successional or abandoned agricultural fields, pastures, etc. Examples are known from the Eastern and Western Highland Rim of Tennessee, related areas of Kentucky, as well as possibly Alabama. It is described and documented from the Cumberland Plateau and Interior Low Plateau, but it could range into the adjacent Upper East Gulf Coastal Plain. <i>Schizachyrium scoparium</i> is codominant along with a variable mixture of the nominal <i>Andropogon</i> species. In examples from the Eastern Highland Rim of Coffee County, Tennessee (Arnold Air Force Base), other dominant grasses may include <i>Dichanthelium aciculare (= Dichanthelium angustifolium), Gymnopogon brevifolius</i>, and <i>Dichanthelium dichotomum var. dichotomum (= var. ramulosum)</i>. On the Western Highland Rim of middle Tennessee, these barrens occur on winter-wet, summer-dry loessal soils, which are generally deep, with chert fragments; rock outcrops are absent. The presence of this vegetation may be related to remnant surficial deposits of Cretaceous gravels which remain on some of the high flat ridges in this landscape. Some forbs found in these examples include <i>Asclepias amplexicaulis, Sericocarpus linifolius, Boltonia</i> sp., <i>Comandra umbellata, Eupatorium album, Eupatorium serotinum, Galium pilosum, Helianthus atrorubens, Helianthus mollis, Hypericum virgatum (= Hypericum denticulatum var. acutifolium), Hypericum punctatum, Mimosa microphylla (= Schrankia microphylla), Monarda fistulosa, Parthenium integrifolium, Pycnanthemum tenuifolium, Rudbeckia hirta, Sabatia angularis</i>, and <i>Tephrosia virginiana</i>. |
