This forest is currently only known from moderately well-drained alluvial floodplains of the Leon River and Cowhouse Creek in the Lampasas Cutplain of central Texas. It may also extend into adjacent ecoregions. The vegetation is characterized by a closed-canopy forest dominated by <i>Ulmus crassifolia</i> and/or <i>Carya illinoinensis</i>. The canopy may also include <i>Celtis laevigata var. laevigata, Celtis laevigata var. texana, Fraxinus pennsylvanica, Quercus macrocarpa, Juniperus virginiana</i>, and <i>Ulmus americana</i>. In addition to canopy species, the midstory often includes <i>Acer negundo, Maclura pomifera, Sideroxylon lanuginosum</i>, and <i>Sapindus saponaria</i>. The understory is typically open with scattered shrubs, including canopy saplings and <i>Forestiera pubescens, Callicarpa americana, Cornus drummondii, Frangula caroliniana</i>, and <i>Ilex decidua</i>. Herbaceous ground cover is typically greater than 75% cover of a mixture of graminoids and forbs, including <i>Elymus virginicus</i> (which can have high cover), <i>Carex bulbostylis, Geum canadense, Sanicula canadensis, Ruellia drummondiana, Chasmanthium latifolium, Verbesina virginica, Commelina erecta, Vernonia baldwinii, Symphyotrichum drummondii var. texanum</i>, and <i>Cocculus carolinus</i>. Vines, including <i>Toxicodendron radicans, Parthenocissus quinquefolia, Smilax rotundifolia, Smilax bona-nox</i>, and <i>Vitis cinerea</i>, are a common component of this association and are typically present in all strata. |

This association is described from the least disturbed grasslands present at Fort Hood, Texas. Most occurrences are dominated by <i>Schizachyrium scoparium</i> in a mixture with other grasses, including <i>Sporobolus compositus, Sorghastrum nutans, Bouteloua hirsuta, Bouteloua curtipendula, Aristida purpurea, Muhlenbergia reverchonii</i>, and <i>Bothriochloa laguroides</i>. This association can have a strong component of showy wildflowers, including <i>Liatris mucronata, Calylophus berlandieri, Melampodium leucanthum, Helianthus maximiliani, Oenothera macrocarpa, Silphium albiflorum</i>, and <i>Chamaecrista fasciculata</i>. <i>Salvia texana</i> and <i>Dalea multiflora</i> tend to be abundant in areas with thinner soils. Other characteristic components include <i>Symphyotrichum ericoides, Hedyotis nigricans, Scutellaria wrightii, Thelesperma simplicifolium, Stillingia texana, Agalinis densiflora, Desmanthus</i> spp., <i>Mimosa roemeriana, Asclepias viridiflora</i>, and <i>Asclepias oenotheroides</i>. Occasional woody components include <i>Yucca pallida, Juniperus ashei, Rhus lanceolata, Toxicodendron radicans</i>, and <i>Rubus trivialis</i>. Woody components increase in the absence of fire. |

This post oak - white oak dry-mesic barrens community is found in the Interior Low Plateau of the United States on dry-mesic terraces and midslopes, particularly in the Cretaceous Hills of Illinois, and perhaps elsewhere. This type is restricted to mid and lower slope hillsides and terraces where soils are predominantly thin, well-drained, and gravelly. Canopy closure is incomplete (probably between 10 and 60%, thus varying from savanna to woodland) and is dominated by <i>Quercus stellata</i>, along with <i>Quercus alba</i> and <i>Quercus falcata</i>. Mature trees exhibit short trunks and spreading, open crowns. The subcanopy consists of scattered, small oaks (<i>Quercus stellata, Quercus velutina</i>, and <i>Quercus alba</i>) and <i>Carya glabra</i>. The shrub layer is dominated by <i>Cornus florida</i>, but <i>Aralia spinosa, Sassafras albidum</i>, and <i>Rhus copallinum</i> are also common. The herbaceous layer is quite dense and dominated by <i>Schizachyrium scoparium</i>; a diverse assemblage of grasses and forbs are represented. Characteristic grasses and herbs include <i>Dichanthelium</i> spp., <i>Coreopsis tripteris, Elephantopus carolinianus, Agrimonia pubescens</i>, and <i>Symphyotrichum shortii (= Aster shortii)</i>. Although <i>Toxicodendron radicans</i> and <i>Parthenocissus quinquefolia</i> occur in abundance here, <i>Smilax glauca</i> is characteristic of this dry environment. |

This association represents a provisional type at Canaveral National Seashore that encompasses freshwater marshes dominated by <i>Andropogon brachystachyus</i> and <i>Fuirena scirpoidea</i>. This association was created based on data from one plot at Canaveral, so additional data are needed to fully describe this community. |

This community consists of graminoid-dominated vegetation with scattered shrubs, occurring on moderate to high-elevation peaks and saddles in the Southern Blue Ridge. Characteristically, this vegetation is strongly dominated by <i>Danthonia compressa</i>, or in some areas codominated by the subshrub <i>Sibbaldiopsis tridentata (= Potentilla tridentata)</i>. Other characteristic herbaceous species are <i>Angelica triquinata, Carex pensylvanica, Carex debilis, Carex intumescens, Carex brunnescens, Deschampsia flexuosa, Erythronium umbilicatum ssp. monostolum, Gentiana austromontana, Gentianella quinquefolia, Houstonia serpyllifolia, Ionactis linariifolius (= Aster linariifolius), Lysimachia quadrifolia, Oclemena acuminata (= Aster acuminatus), Potentilla canadensis, Prenanthes roanensis, Smilax herbacea, Solidago bicolor, Solidago glomerata, Stachys clingmanii</i>, and <i>Trautvetteria caroliniensis var. caroliniensis</i>. The floristic composition is a mixture of widespread species, northern disjunct species, such as <i>Agrostis mertensii, Carex siccata (= Carex aenea), Minuartia groenlandica, Packera schweinitziana (= Senecio schweinitzianus)</i>, and <i>Sibbaldiopsis tridentata</i>, and Southern Appalachian endemics, such as <i>Erythronium umbilicatum ssp. monostolum, Geum geniculatum, Geum radiatum, Houstonia serpyllifolia, Lilium grayi, Prenanthes roanensis, Solidago glomerata</i>, and <i>Stachys clingmanii</i>). Typical shrubs (which may occur as scattered individuals or as patches) are <i>Rhododendron calendulaceum, Rhododendron catawbiense, Menziesia pilosa, Vaccinium corymbosum</i>, and <i>Rubus canadensis</i>. Species indicative of past grazing include <i>Phleum pratense, Agrostis gigantea, Hieracium scabrum, Rumex acetosella</i>, and <i>Prunella vulgaris</i>. This community occurs on high-elevation (usually above 1350 m [4500 feet]), often south- to southwest-facing domes, ridgetops, and gentle slopes. Strong winds, high rainfall, frequent fog, shallow rocky soils, and extremes of temperature and moisture are characteristic of these environments. It is known from the highest elevations of the southern Appalachian Mountains. It is typically surrounded by dwarfed forests dominated by <i>Fagus grandifolia</i> or <i>Quercus rubra</i>. |
