This dwarf pitch pine community is restricted to a single occurrence in New York on a flat-topped summit with thin soils over a white quartzite conglomerate. The flat topography and impermeable substrate at times fosters a seasonally high water table, although this community is not a wetland. The physiognomy is a dense, compact and short (2 m) canopy of pines and huckleberry. This community is dominated by dwarf individuals of <i>Pinus rigida</i> and by <i>Gaylussacia baccata</i>. Other characteristic woody plants associated with the dwarf pine are <i>Viburnum nudum var. cassinoides, Photinia melanocarpa (= Aronia melanocarpa)</i>, and <i>Betula populifolia</i>. A low-shrub stratum is composed of <i>Vaccinium angustifolium, Vaccinium pallidum, Comptonia peregrina</i>, and <i>Kalmia angustifolia</i>. Other associated species in the ground layer include <i>Gaultheria procumbens, Cornus canadensis, Maianthemum canadense, Cypripedium acaule</i> and <i>Melampyrum lineare</i>. |

This is a natural grassland vegetation type reported from Virginia's southwestern Piedmont (Franklin County). This community occurs on thin Alfisols or Mollisols developed over serpentinite, dunite, or a similar ultramafic rock. Soils at the Virginia site are described as extremely friable, reddish brown, drought-prone, with a pH of 7 and a calcium:magnesium ratio of 0.22, comparable to serpentine soils. The community occurs at moderate elevations on gentle to steep slopes with a western or southwestern aspect. It occurs as herbaceous grassland openings with scattered, stunted trees, most typically <i>Quercus stellata, Quercus marilandica, Pinus virginiana</i>, and <i>Juniperus virginiana var. virginiana</i>. Shrubs are very sparse to absent. The vegetation has a dense grassy layer dominated by <i>Schizachyrium scoparium, Sporobolus heterolepis</i>, and <i>Packera plattensis</i>. |

This alliance contains basins, swales, moats of bog mats, and pondshores dominated by ~Dulichium arundinaceum$. Communities in this alliance typically occur in basins of porous substrate where the water level drops significantly during dry years. Substrate is variously mucky or sandy. Typical communities also contain a mix of low grasses, sedges, rushes, and scattered shrubs. This alliance is wide-ranging and poorly known. |

This red pine forest association is known from high elevations in Pendleton and Hardy counties, West Virginia, on steep, north- to northwest-facing slopes near the summit, on sandy acidic soils over sandstone. This association is a mostly evergreen forest or woodland strongly dominated by <i>Pinus resinosa</i>. Canopies are stunted, rarely reaching 20 m tall, and range from even-aged and closed in younger stands to open and multi-aged in older stands. Canopy associates include <i>Acer rubrum, Betula lenta, Pinus rigida, Quercus rubra, Pinus strobus, Pinus pungens</i>, and <i>Pinus virginiana</i>. Additional species in the subcanopy include <i>Amelanchier arborea, Acer pensylvanicum, Betula papyrifera, Hamamelis virginiana, Sorbus americana</i>, and <i>Tsuga canadensis</i>. Shrubs include <i>Kalmia latifolia, Menziesia pilosa, Vaccinium angustifolium, Rhododendron prinophyllum (= Rhododendron roseum), Rhododendron calendulaceum</i>, and <i>Gaylussacia baccata</i>. Regeneration of <i>Pinus resinosa</i> in the shrub layers varies from absent in even-aged closed-canopy stands to abundant in more open stands. The sparse herbaceous layers are characterized by <i>Polypodium appalachianum, Gaultheria procumbens, Solidago curtisii, Dryopteris marginalis, Calamagrostis porteri, Epigaea repens, Deschampsia flexuosa, Dryopteris intermedia, Carex pensylvanica, Maianthemum canadense, Oclemena acuminata</i>, and <i>Polygala paucifolia</i>. Mosses include species of <i>Leucobryum</i> and <i>Polytrichum</i>. Common lichens on rock include <i>Lasallia papulosa</i> and <i>Lasallia pensylvanica</i>. This association is not likely to be fire-dependent but is probably fire-adapted. Abundant regeneration of <i>Pinus resinosa</i> in this association has been documented in stands without recent fire. Regeneration occurs in gaps caused by insect pest outbreaks and by ice and wind storms. Cohorts have also established following human-ignited fires and abandonment of pastures. There is evidence of post-settlement fires in many stands of this association, but natural ignitions are rare in its range. |

This association is a seasonally flooded forest of shallow basins and other depressions of the Coastal Plain of the Chesapeake Bay region. The substrate is characterized by mineral soils, generally acidic, gleyed to mottled, sandy or clay loams. Characteristic tree species include <i>Acer rubrum, Liquidambar styraciflua</i>, and <i>Nyssa sylvatica</i>, which are nearly constant in the canopy. Associates include <i>Ilex opaca, Magnolia virginiana, Nyssa biflora, Sassafras albidum, Quercus palustris, Pinus taeda</i>, and <i>Quercus phellos</i>, and occasionally <i>Quercus falcata, Quercus lyrata</i>, or <i>Betula nigra</i>. The shrub layer is characterized by <i>Leucothoe racemosa, Vaccinium corymbosum, Clethra alnifolia, Lindera benzoin, Ilex verticillata</i>, and <i>Rhododendron viscosum</i>. <i>Smilax rotundifolia</i> is a particularly characteristic vine. The herbaceous layer is generally sparse but may include <i>Mitchella repens, Osmunda cinnamomea, Chasmanthium laxum, Woodwardia areolata, Onoclea sensibilis, Osmunda regalis, Carex albolutescens, Carex debilis var. debilis, Scirpus cyperinus, Juncus effusus</i>, and <i>Polygonum</i> spp. <i>Carex joorii</i> is inconstant but locally abundant in some stands in the southern part of the range. |
