<i>Pinus palustris</i> (and sometimes <i>Pinus taeda</i> or <i>Pinus serotina</i>) dominates the open canopy of this Mid-Atlantic Coastal Plain flatwoods. The shrub layer is often dense, dominated by <i>Gaylussacia frondosa, Ilex glabra, Gaylussacia baccata, Clethra alnifolia, Morella cerifera, Gaylussacia dumosa, Lyonia mariana</i>, and <i>Arundinaria tecta</i>. Other characteristic species include <i>Vaccinium crassifolium, Pteridium aquilinum var. pseudocaudatum</i>, and <i>Pyxidanthera barbulata</i>. This community is poorly understood, since few examples remain, and these are in poor condition. These communities are moist to wet longleaf pine flatwoods north of the range of <i>Aristida stricta</i>. |

This alpine fell-field association is found throughout Colorado's Rocky Mountains and in western and central Montana north into Alberta. This vegetation type represents the drier, mostly subxeric to submesic occurrences of <i>Dryas octopetala</i>-dominated dwarf-shrublands. It occurs predominantly in alpine environments (well above treeline); actual elevations vary from 3370 to 3900 m in the Colorado alpine to between 1700 and 2400 m in northwestern Montana. Typical terrain is moderately to steeply sloping, and all aspects are represented. The determining environmental parameter appears to be wind-scouring with sites blown snow-free in winter. Soils are very poorly developed and well- to rapidly drained. The association occurs on a wide variety of parent materials, though typically on residual and colluvial landforms. Where not protected by a dwarf-shrub mat, ground surfaces are composed of 5 to 60% exposed gravel, cobble and, to a much lesser degree, soil; litter can only accumulate immediately under the protection of the dwarf-shrub cover.<br /><br />A mat of the dwarf-shrub <i>Dryas octopetala</i> dominates the visual aspect, with variable cover ranging from 10 to 80%. Usually mats occur in relatively evenly spaced windrows oriented perpendicular to the prevailing wind or along the edges of stepped terracettes. Other dwarf-shrubs include <i>Salix arctica, Dasiphora fruticosa ssp. floribunda, Arctostaphylos uva-ursi, Juniperus communis</i>, and <i>Salix reticulata</i>. Of the herbaceous component, graminoids generally have greater cover than forbs, a condition which is presumed to indicate the relatively xeric nature of the type. <i>Carex rupestris</i> has high constancy and occasionally is the dominant graminoid, but in Glacier National Park stands, there is no one dominant graminoid, only a variable suite of xeric-adapted species, including <i>Carex nardina, Calamagrostis purpurascens, Calamagrostis koelerioides, Festuca brachyphylla, Poa alpina</i>, and <i>Trisetum spicatum</i>. Typically the forb component does not exceed 10% cover, and that of individual forbs does not exceed 5%; those with highest constancy include <i>Minuartia obtusiloba, Myosotis asiatica, Geum rossii, Artemisia scopulorum, Saxifraga bronchialis, Silene acaulis, Oxytropis campestris, Rhodiola rosea, Solidago multiradiata, Potentilla diversifolia</i>, and <i>Smelowskia calycina</i>. Cover of mosses and lichens is very low. |

This medium to tall willow shrub association occurs on saturated point bars and active stream channels along broad, sandy-bottom or braided streams in the foothills (1740-2440 m [5700-8000 feet]) of Colorado and may occur in New Mexico. The association is dominated by <i>Salix ligulifolia</i> mixed with <i>Salix exigua</i>. Other shrubs include <i>Salix lucida ssp. caudata, Alnus incana, Symphoricarpos</i> spp., <i>Betula occidentalis</i>, and <i>Quercus gambelii</i>. Other shrubs with less than 10% cover may include <i>Prunus virginiana, Rosa woodsii</i>, and <i>Crataegus rivularis</i>. The herb layer is typically quite diverse, dominated by any number of species. Common species include <i>Carex pellita, Carex nebrascensis, Lactuca serriola, Juncus arcticus ssp. littoralis, Muhlenbergia asperifolia, Rudbeckia laciniata, Calamagrostis stricta, Eleocharis palustris</i>, and a variety of weeds. |

This community consists of one of two prairie-like woodlands associated with diabase in the Carolina Piedmont, representing the south-central North Carolina Piedmont and adjacent South Carolina type. This community has very variable structure and species composition, depending on land-use history and local fire regime. Historically, this community is believed to have been herbaceous-dominated with a widely scattered, open canopy of trees and patches of shrubs and fire-sprouting overstory species. Due largely to fire suppression, most known examples occur as a dense woody growth with generally closed canopy. A few examples which are being restored have a more typical, stunted woodland structure, with canopy cover ranging from 40-70%. High-quality examples are expected to have an open grass-dominated herb layer, and an overstory dominated by <i>Quercus stellata</i>, often with some component of <i>Pinus echinata, Quercus marilandica</i>, and <i>Juniperus virginiana var. virginiana</i>. Common subcanopy species may include <i>Cercis canadensis</i> and <i>Cornus florida</i>. Common shrubs include <i>Viburnum rafinesqueanum, Ilex longipes, Vaccinium arboreum, Symphoricarpos orbiculatus</i>, and <i>Hypericum prolificum</i>. Common herb species include <i>Schizachyrium scoparium var. scoparium, Andropogon virginicus, Silphium terebinthinaceum, Symphyotrichum patens var. patens, Symphyotrichum georgianum, Ionactis linariifolius, Solidago nemoralis, Coreopsis major, Eryngium yuccifolium, Phlox nivalis, Oligoneuron album, Oligoneuron rigidum, Opuntia humifusa, Phemeranthus teretifolius, Trichostema brachiatum, Ratibida pinnata, Sporobolus vaginiflorus, Sporobolus clandestinus, Ranunculus fascicularis, Symphyotrichum laeve, Veronicastrum virginicum, Liatris aspera, Liatris</i> spp., <i>Verbena simplex, Aquilegia canadensis, Senna marilandica, Physostegia virginiana</i>, and <i>Clematis ochroleuca</i>. |
