This alliance occurs in subalpine and alpine habitats of the high mountains of the Pacific Northwest. The climate is cold and snowy with severe winds, snow abrasion, and a short growing season. Elevations where the alliance is found range from 1700-2400 m in the Cascades. Stands of this alliance typically occur on exposed, well-drained substrates. There are often late-lying snowpacks but some late-summer drought is possible. In the northern Cascades, the communities have been described as snowbed types. Vegetation in this alliance forms sparse, distinctive communities with ~Eriogonum pyrolifolium$ usually dominant, but often low in cover. ~Luzula piperi$ is the most common associate, but ~Carex pyrenaica, Erigeron aureus, Poa secunda (= Poa sandbergii), Sibbaldia procumbens$, and ~Antennaria alpina$ occur in stands in the North Cascades. |

This community occupies shallow depressions in ridgetop or plateau-top sandstone of the Cumberland Plateau and Ridge and Valley provinces. This association has a closed to open canopy dominated by Quercus phellos. In addition, Liquidambar styraciflua, Acer rubrum, Nyssa sylvatica, Quercus rubra, and Pinus taeda can also be canopy components. Shrubs and woody vines are sparse, and include Toxicodendron radicans, Cephalanthus occidentalis, and Campsis radicans. Herbs are also sparse. Most characteristic is Chasmanthium laxum. Other herbs include Carex glaucescens, Dulichium arundinaceum, Dichanthelium spp., Rhynchospora corniculata, Juncus repens, and Chasmanthium sessiliflorum. Sphagnum lescurii and other Sphagnum spp. can form scattered patches or fairly continuous cover. |

This association occurs on xeric hammocks of Florida's Lake Wales Ridge on deep coarse sands. These forests are dominated by Quercus geminata with Sabal etonia as an important shrub. Other characteristic species include Quercus myrtifolia, Serenoa repens, Lyonia ferruginea, Garberia heterophylla, Vaccinium stamineum, Cladina evansii, and Morella cerifera (= Myrica cerifera). Lichens are also important. |

This barrens or post oak openings community is found in the midwestern United States in southern Indiana and Ohio. Stands occur on rolling hill-and-swale topography over limestone or shale bedrock. The soils are stony and excessively well-drained. This is a prominent community on the Mitchell Karst Plain in south-central Indiana. There, it occurs on rolling hill-and-swale topography on a large sinkhole plain over limestone bedrock. Soils are formed from chert residue left from the erosion of limestone bedrock. These soils are stony, acidic, and excessively well-drained. In Ohio, this community occurs in the unglaciated Bluegrass Region, north of West Union in Adams County, where it is found only over Crab Orchard Shale, on slight slopes or mounded outcrops. On slopes, deep erosional gullies are usually present. Crab Orchard Shale is calcareous and weathers to a light brown to yellowish heavy silt loam containing scattered pieces of dolomite. Fire, drought and grazing are factors in maintaining the open woody character of this type. Vegetation may be sparse, consisting of xeric species and stunted individuals of species that reach considerable size elsewhere. Graminoids, such as <i>Schizachyrium scoparium</i> and <i>Sorghastrum nutans</i>, form most of the vegetation cover in this community, but tree canopy species may include <i>Juniperus virginiana var. virginiana, Quercus alba, Quercus imbricaria, Quercus marilandica, Quercus stellata</i>, and <i>Quercus velutina</i>. Herbaceous species which may be present include <i>Aconitum uncinatum, Allium cernuum, Andropogon gerardii, Aristida longispica, Asclepias amplexicaulis, Carex meadii, Danthonia spicata, Eryngium yuccifolium, Euphorbia corollata, Helianthus mollis, Helianthus hirsutus, Houstonia</i> sp., <i>Liatris cylindracea, Liatris squarrosa, Lobelia spicata, Panicum flexile, Pycnanthemum tenuifolium, Rudbeckia hirta, Salix humilis, Silphium trifoliatum</i>, and <i>Sporobolus vaginiflorus</i>. |
