This saturated longleaf pine - pond pine woodland association is restricted to wet and moist Ultisols of the Atlantic Coastal Plain of North and South Carolina. The open canopy of this association is dominated by a combination of <i>Pinus palustris</i> and <i>Pinus serotina</i>. <i>Pinus taeda</i> may also be present. <i>Ilex glabra, Clethra alnifolia</i>, and <i>Gaylussacia frondosa</i> are common in the shrub layer. <i>Sporobolus pinetorum, Aristida stricta, Ctenium aromaticum</i>, and <i>Eryngium integrifolium</i> are in the herbaceous layer. <i>Sporobolus pinetorum</i> may dominate, with <i>Ctenium aromaticum</i> of secondary importance. Some stands in the wiregrass gap of South Carolina (e.g., Francis Marion National Forest) will not have <i>Aristida stricta</i> present. |

This spruce-fir riparian forest occurs in the southern Rocky Mountains in Colorado. It occurs on heavily forested reaches of first- and second-order streams above 2440 m (8000 feet) in elevation where <i>Abies lasiocarpa - Picea engelmannii</i> forests also occur on adjacent hillslopes. It is found on stream benches and banks in narrow, V-shaped valleys most commonly within 4.6-6.1 m (15-20 feet) of the channel edge and rarely more than 0.6 m (2 feet) above the streambank. Stream channels vary in their morphology; they can be narrow to wide and steep to flat and sinuous. Soils are shallow, dark-colored layers of loamy sands, silty loams, and sandy clay loams over cobbly alluvium with high organic matter content in the top 50.8 cm (20 inches) and mottles at 101.6 cm (40 inches). Stands have an evergreen needle-leaved tree canopy dominated by <i>Abies lasiocarpa</i> and <i>Picea engelmannii</i>. Occasional canopy associates can include <i>Picea pungens, Pinus contorta</i>, or <i>Populus tremuloides</i>. Tall <i>Alnus incana</i> and <i>Salix drummondiana</i> grow in a thick band along the edge of the stream. At lower elevations, <i>Alnus incana</i> is more abundant than <i>Salix drummondiana</i>. At mid elevations, the two shrubs can be codominant. At higher elevations, <i>Salix drummondiana</i> becomes dominant and <i>Alnus incana</i> drops out, forming ~<i>Abies lasiocarpa - Picea engelmannii / Salix drummondiana</i> Swamp Forest (CEGL000327)$$. In stands where <i>Alnus incana</i> and <i>Salix drummondiana</i> codominate the shrub layer, the stand should be classified as CEGL000327. Additional tall shrubs that can occur in this association include <i>Cornus sericea, Salix geyeriana, Salix monticola, Lonicera involucrata</i>, and <i>Acer glabrum</i>. The herbaceous layer is usually rich in forb species, with total herb cover ranging from 20-70%. Species often include <i>Corydalis caseana ssp. brandegeei, Heracleum maximum, Oxypolis fendleri, Mertensia ciliata, Mertensia franciscana, Maianthemum racemosum ssp. amplexicaule, Streptopus amplexifolius, Pyrola asarifolia, Cardamine cordifolia, Hydrophyllum fendleri</i>, among many others. Graminoids commonly include <i>Calamagrostis canadensis, Carex aquatilis, Glyceria striata, Elymus glaucus, Carex disperma</i>, and <i>Bromus ciliatus</i>. Bryophyte cover is often moderate. |

This shrubland association occurs in coastal California on gentle to steep slopes of flat to variable aspect at low elevations between 2 and 547 m. It is characterized by a dominance of <i>Baccharis pilularis</i> and subdominance of <i>Artemisia californica</i> in the shrub layer. The herbaceous layer is more variable than the <i>Baccharis pilularis</i> / annual grass - herb association and tends to have more cover by tall exotic herbs such as <i>Brassica nigra</i> and <i>Foeniculum vulgare</i>. The emergent tree layer is generally absent but can include exotic ruderals such as <i>Schinus molle</i> and <i>Eucalyptus</i> spp., as well as the native <i>Quercus lobata</i> and <i>Quercus agrifolia</i>. |

This community includes narrow, almost pure stands of <i>Spartina cynosuroides</i> along tidal creeks and sloughs or on levees of oligohaline tidal marshes along the central Atlantic coast. Some occurrences are nearly monospecific, while others have a diverse component of other graminoids and forbs. Where mixed, associated plants include <i>Schoenoplectus pungens, Bolboschoenus robustus, Schoenoplectus americanus, Kosteletzkya virginica, Hibiscus moscheutos, Amaranthus cannabinus, Panicum virgatum, Peltandra virginica</i>, and <i>Polygonum punctatum</i>. Where more saline, <i>Spartina alterniflora</i> and <i>Iva frutescens</i> can become more frequent. Where less saline, associates can include <i>Schoenoplectus tabernaemontani, Pontederia cordata, Peltandra virginica, Leersia oryzoides, Mikania scandens, Rumex verticillatus, Echinochloa walteri, Polygonum hydropiperoides</i>, and <i>Typha angustifolia</i> (or <i>Typha domingensis</i> in the south), among others. In more disturbed areas, this association can be displaced by <i>Phragmites australis</i>. |

This open shrubland community is a nearly treeless, open grassy expanse including <i>Aristida beyrichiana, Aristida spiciformis, Aristida purpurascens, Andropogon virginicus, Andropogon brachystachyus, Ctenium aromaticum</i>, and <i>Eragrostis</i> spp. Sparse to dense cover of low, scrubby <i>Serenoa repens</i> and scattered patches of low shrubs including <i>Quercus pumila, Quercus minima, Asimina</i> spp., <i>Ilex glabra, Lyonia ferruginea, Lyonia fruticosa, Lyonia lucida, Vaccinium myrsinites</i>, and <i>Morella cerifera</i> are often present, with the density highly dependent upon fire history. Infrequently burned prairies and prairies which are burned only during the wet growing season and/or dormant season develop greater shrub and palmetto densities. An occasional tree may occur (less than 2 trees/ 1.0 ha), typically <i>Pinus elliottii var. densa</i> or <i>Sabal palmetto</i>. Other typical plants include <i>Andropogon capillipes, Axonopus fissifolius, Carphephorus</i> sp., <i>Centella erecta, Chaptalia tomentosa, Drosera brevifolia, Sorghastrum secundum, Schizachyrium scoparium var. stoloniferum, Pityopsis graminifolia, Eryngium aromaticum, Liatris</i> spp., <i>Pterocaulon pycnostachyum, Piloblephis rigida, Lilium catesbaei, Sabatia brevifolia, Polygala</i> spp., <i>Solidago</i> spp., and <i>Hyptis alata</i>. This community is endemic to Florida and occurs within a matrix of mesic pine flatwoods in the southern portion of the state on flat, moderately to poorly drained sandy sites. These areas are seldom inundated but may flood with several centimeters of water for short periods after heavy summer rains. |

This community occupies wet alluvial bottomlands and beaver ponds in the Central Appalachians and adjacent ecoregions. Parent materials are alluvium derived mainly from acidic sandstones and shales. Surface soils are poorly drained, acidic clay loams. This small-patch wetland community is dominated by grasses and forbs, with scattered trees and shrubs. The dominant grasses are <i>Leersia oryzoides</i> and <i>Phalaris arundinacea</i> with <i>Leersia</i> strongly dominant at most sites. <i>Sagittaria latifolia</i> has high constancy and cover, except at higher elevations. <i>Scirpus cyperinus</i> has high constancy. Additional characteristic herbs include <i>Boehmeria cylindrica, Carex gynandra, Carex intumescens, Carex baileyi, Dichanthelium clandestinum, Dulichium arundinaceum, Eutrochium fistulosum, Galium tinctorium, Impatiens capensis, Juncus effusus, Lobelia siphilitica, Ludwigia palustris, Lycopus uniflorus, Lycopus virginicus, Lysimachia terrestris, Mimulus ringens, Polygonum sagittatum, Scirpus atrovirens</i>, and <i>Typha latifolia</i>. Areas with longer standing water may have aquatic species, including <i>Callitriche heterophylla</i> and <i>Sparganium</i> spp. Scattered small trees include <i>Robinia pseudoacacia, Salix nigra</i>, and <i>Fraxinus pennsylvanica</i>. The exotic shrub <i>Rosa multiflora</i> is sometimes invasive in this community. <i>Cornus amomum</i> is a characteristic native shrub. |
