This association spans a broad geographic range of subxeric longleaf pine woodlands of the Inner Coastal Plain from central South Carolina to the Alabama border. It occurs on silty sites. Because of its broad spatial distribution, there is some turnover of species in this type depending on geographic position. However, the subcanopy is consistently dominated by <i>Quercus margarettae</i> with slightly lesser amounts of <i>Quercus laevis</i> and <i>Quercus incana</i>, reflecting the subxeric, silty nature of the sites. The high frequency of <i>Toxicodendron pubescens</i> also suggests the silty, subxeric nature of soils this type occurs on, as does the abundance of legumes. <i>Aristida beyrichiana</i> can be a ground layer dominant, but the type extends beyond the range of the species, both in central South Carolina and in western Georgia. The herbaceous layer is species-rich, reflecting the silty nature of the soils of this type. Other characteristic species include <i>Carya tomentosa, Rhus copallinum, Ceanothus americanus, Lespedeza hirta, Mimosa microphylla, Clitoria mariana, Ionactis linariifolius, Pityopsis graminifolia</i>, and <i>Solidago odora</i>. |

This forest, dominated by <i>Nyssa aquatica</i> and <i>Nyssa biflora</i> in varying proportions, is found along shallow borders of alluvial swamps and flats near uplands. It is a Zone II community. The range has not been completely assessed; it is theoretically possible on the Atlantic Coastal Plain from North Carolina to southern Georgia, the Gulf Coastal Plain from about Tallahassee west to southeastern Texas, and the Mississippi Alluvial Plain to southern Arkansas and western Tennessee. <i>Taxodium distichum</i> may occur in the canopy of this community, but is not a dominant (usually less than 25% cover). Other tree canopy/subcanopy species are <i>Fraxinus pennsylvanica, Salix nigra, Populus heterophylla</i>, and <i>Carpinus caroliniana</i>. Other shrub and herbaceous species are <i>Eubotrys racemosa, Cyrilla racemiflora, Planera aquatica</i>, and <i>Saururus cernuus</i>. <i>Decumaria barbara, Toxicodendron radicans, Nekemias arborea</i>, and <i>Bignonia capreolata</i> are commonly occurring vines, but have less than 10% cover. |

This forest occurs in wetter sloughs associated with <i>~Quercus michauxii - Quercus pagoda / Clethra alnifolia - Leucothoe axillaris</i> Wet Flatwoods Forest (CEGL007449)$$, on extensive flats with a high water table providing seasonally to semipermanently saturated (and rarely flooded) conditions. This forest is believed to occur from Virginia to Georgia, in the Atlantic Coastal Plain. The canopy is dominated by <i>Quercus laurifolia</i>, with lesser amounts of <i>Nyssa biflora</i> and <i>Acer rubrum var. trilobum</i> often present as well. <i>Clethra alnifolia</i> and <i>Leucothoe axillaris</i> are typical shrubs. Herbs including <i>Osmunda regalis, Saururus cernuus</i>, or <i>Woodwardia areolata</i> may be more abundant than the shrubs. |

This broadly defined, successional wetland forest is dominated by <i>Pinus taeda</i> and <i>Liriodendron tulipifera</i>, but many other canopy species are usually present. <i>Lindera benzoin</i> is a typical shrub, and <i>Carex crinita</i> is a typical herb. More information is needed on the detailed floristics of this association. It develops in river floodplain alluvial terraces along streams following major disturbances such as blowdowns, logging, and agriculture. |

This saturated seepage forest occurs in the Upper East Gulf Coastal Plain and adjacent Piedmont of the southeastern United States. It can occur in situations associated with streams, or isolated from other wetlands on sideslopes. The canopy is dominated by the nominal species, <i>Magnolia virginiana</i> and <i>Nyssa biflora</i>; <i>Acer rubrum var. trilobum, Liquidambar styraciflua, Liriodendron tulipifera, Pinus taeda</i>, and <i>Quercus nigra</i> can also be important. The subcanopy typically contains the canopy species and additionally <i>Oxydendrum arboreum</i>. These species may also occur in the shrub stratum, along with <i>Aronia arbutifolia, Alnus serrulata, Arundinaria tecta, Illicium floridanum, Itea virginica, Eubotrys racemosa, Morella caroliniensis, Rhododendron</i> sp. (deciduous), <i>Vaccinium fuscatum</i>, and <i>Viburnum nudum var. nudum</i>. Lianas include <i>Decumaria barbara, Smilax laurifolia, Smilax rotundifolia, Toxicodendron radicans</i>, and <i>Vitis rotundifolia</i>. Herbs are sparse, consisting primarily of <i>Mitchella repens, Osmunda cinnamomea, Osmunda regalis var. spectabilis</i>, and <i>Woodwardia areolata</i>. <i>Sphagnum</i> spp. are usually abundant. |

This association is found in the upper montane and subalpine zone of the Rocky Mountains from north-central Colorado to southern Alberta. It is more common near and east of the Continental Divide, but occurs in the Uinta Mountains of northern Utah and in Idaho. Elevations range from 2950-3120 m (9700-10,240 feet) in northern Colorado down to 950-1800 m (3100-5900 feet) in the northern Rocky Mountains. It typically occurs on cold, dry-mesic sites where cold air accumulates causing high diurnal temperature fluctuations often with frequent summer frosts and high daily maximum temperatures. Topography is flat to gently undulating or moderately sloping terrain typically occurring on valley bottoms, terraces, lower slopes, and benches with variable aspects, but also on steep canyon slopes and benches, plateau tops and adjacent upper slopes in the Uinta Mountains. Soils are typically well-drained, moderately deep, acidic, gravelly or non-gravelly sandy loam, loam, silt loam, silt or less frequently clay that are typically derived from a variety of noncalcareous parent materials. Ground cover is mostly litter, often with duff over 3 cm deep. The vegetation is characterized by a <i>Pinus contorta</i>-dominated tree canopy with <i>Vaccinium cespitosum</i> dominating or codominating the patchy to continuous dwarf-shrub layer. The tree canopy varies from moderately dense to nearly closed (40-90% cover) and is often composed solely of <i>Pinus contorta</i>. However, in some stands scattered <i>Abies lasiocarpa, Larix occidentalis, Picea engelmannii, Pinus albicaulis, Populus tremuloides</i>, or <i>Pseudotsuga menziesii</i> trees may be present, especially in the subcanopy. Some stands have tree saplings and scattered shrubs. <i>Vaccinium cespitosum</i> (indicator species) is usually dominates or codominates the dwarf-shrub layer. Other dwarf-shrubs may include low cover of <i>Arctostaphylos uva-ursi, Paxistima myrsinites, Ribes</i> spp., <i>Linnaea borealis</i> (on more mesic sites), or <i>Juniperus communis</i> and <i>Vaccinium scoparium</i> (drier sites). The herbaceous layer is sparse to moderately dense (to 30% cover) and is typically dominated or codominated by perennial graminoids such as <i>Calamagrostis rubescens, Danthonia intermedia, Deschampsia cespitosa, Carex geyeri, Carex rossii</i>, or <i>Festuca</i> spp. Forbs are generally have sparse cover but may be diverse. Mosses and lichens are common (5-20% cover) on some sites. |
