This herbaceous tall-herb type occurs on moist to temporarily flooded floodplains in the Allegheny Mountains region of West Virginia, at elevations between 370 and 1220 m. It is a small-patch type that occupies flat to gently sloping land (0-3° slopes) adjacent to small streams. Occasional flooding keeps this community open and prevents buildup of organic material in the substrate. Flooding can occur at any time of year. This type is common in beaver-influenced wetlands and on disturbed ground. It is likely to be present on the landscape as long as natural (beaver and flooding) and man-made disturbance regimes persist. Its present distribution is probably larger than its presettlement distribution, when disturbances were less widespread. Soil texture is variable and may include well-drained to poorly drained sandy loam, silt loam, or silty clay, with pH averaging 4.0, underlain by alluvial deposits including stratified sediments, cobbles, and woody debris. A few percent cover of trees and shrubs may be present, including <i>Acer rubrum, Cornus amomum, Crataegus</i> spp., <i>Hypericum densiflorum, Ilex montana, Picea rubens, Prunus serotina var. serotina, Salix sericea, Sambucus canadensis</i>, and <i>Spiraea alba</i>. The herbaceous layer has a number of species with fairly high constancy and cover, including <i>Euthamia graminifolia var. graminifolia, Solidago rugosa, Juncus effusus, Dichanthelium clandestinum, Thelypteris noveboracensis, Polygonum sagittatum, Clematis virginiana, Galium tinctorium, Doellingeria umbellata var. umbellata, Dennstaedtia punctilobula</i>, and <i>Carex scoparia var. scoparia</i>. Other frequent or locally abundant herbaceous species include <i>Symphyotrichum lanceolatum var. lanceolatum, Oxypolis rigidior, Scirpus cyperinus, Agrostis perennans, Impatiens capensis, Galium aparine, Eupatorium fistulosum, Onoclea sensibilis, Lycopus uniflorus var. uniflorus, Rubus hispidus, Poa pratensis ssp. pratensis, Carex gynandra, Osmunda cinnamomea var. cinnamomea, Hypericum mutilum, Eleocharis tenuis, Carex atlantica, Dichanthelium dichotomum, Solidago canadensis, Vernonia noveboracensis, Verbesina alternifolia, Symphyotrichum praealtum, Aconitum uncinatum, Stellaria longifolia var. longifolia, Carex squarrosa</i>, and <i>Carex annectens</i>. Cover by nonvascular plants is minimal. Mean species richness of all vascular plants and any nonvascular plants with cover >1% is 28 taxa per 400 m2 for 20 plots in West Virginia. |

This maritime-influenced, upland <i>Pinus elliottii var. elliottii</i> woodland occurs on barrier islands and near-coastal areas of the East Gulf Coastal Plain and adjacent South Atlantic region. In addition to <i>Pinus elliottii var. elliottii</i>, stands sometimes contain an admixture of <i>Pinus palustris</i>. In the past, canopy structure in natural stands was open, but now it varies to a more closed structure. A subcanopy is sometimes present and can include <i>Quercus virginiana, Quercus geminata, Quercus hemisphaerica</i>, and <i>Magnolia grandiflora</i>. Typical understory species include <i>Ilex vomitoria, Serenoa repens</i>, and <i>Morella cerifera</i>. Other common shrubs and woody vines are <i>Smilax bona-nox, Smilax auriculata, Smilax laurifolia, Rhus copallinum var. leucantha, Vitis rotundifolia, Vaccinium arboreum</i>, and <i>Persea borbonia</i>. The herb stratum is typically poorly developed but may include <i>Solidago odora var. odora</i> and <i>Tragia urens</i>. On a southern Georgia barrier island, at the Cumberland Island National Seashore, the sparse herb layer contains occasional species expected from more open longleaf pine uplands, including <i>Aristida lanosa, Liatris</i> sp., and <i>Sorghastrum secundum</i>. In northeastern Florida, at the Timucuan Ecological and Historic Preserve, dead and dying <i>Persea borbonia</i> indicate that these maritime flatwoods are being affected by laurel wilt, which is caused by a vascular wilt fungus that is transmitted to species in the Lauraceae family via the non-native redbay ambrosia beetle (<i>Xyleborus glabratus</i>). |

This community is a willow shrubland of low riverbanks along moderate- to high-energy rivers in the northeastern U.S. and High Allegheny Plateau. It occurs on cobble substrates with sand and gravel in areas that are flooded only during high-water events, but receive winter ice-scour. It occupies an intermediate position along a disturbance gradient between open, herbaceous cobble shores and higher floodplain forests. <i>Salix nigra</i> is often dominant or codominant with other willows or dogwoods forming a dense shrub layer. Less frequent shrubs and tree saplings include <i>Salix eriocephala, Salix lucida, Salix sericea, Alnus incana, Alnus serrulata, Cornus amomum, Cornus sericea, Spiraea alba var. latifolia, Platanus occidentalis, Acer rubrum, Acer saccharinum</i>, and <i>Populus deltoides</i>. The herbaceous layer is often sparse but variable in cover and composition, including <i>Carex torta, Panicum dichotomiflorum, Panicum virgatum, Dichanthelium clandestinum, Echinochloa crus-galli, Elymus virginicus, Justicia americana, Boehmeria cylindrica, Polygonum amphibium, Phalaris arundinacea, Calamagrostis canadensis, Apocynum cannabinum, Agrostis</i> spp., <i>Solidago gigantea, Solidago rugosa, Eupatorium maculatum, Rorippa islandica, Lysimachia terrestris, Polygonum</i> spp., and <i>Bidens</i> spp. Invasive, exotic species can be problematic in this community, including <i>Polygonum cuspidatum, Lythrum salicaria, Tussilago farfara</i>, and <i>Cynanchum louiseae</i>. |

Soils are typically deep, fertile, moderately to well-drained and are often derived from calcareous parent materials, with textures including sands, loams, and silt loams. The canopy is dominated by <i>Acer saccharum</i> with <i>Fraxinus americana, Liriodendron tulipifera</i>, and <i>Tilia americana</i> being very characteristic. Associated canopy trees include <i>Quercus rubra, Ostrya virginiana, Ulmus rubra, Acer rubrum, Betula alleghaniensis, Betula lenta, Fagus grandifolia, Juglans nigra, Carya cordiformis</i>, and <i>Prunus serotina</i>.

This oak-pine association occurs in the Sierra Nevada from Butte County to Kern County and in San Benito County. Stands of this woodland are found at low elevations (120-1525 m [400-5000 feet]) on north- to northeast- and south- to southwest-facing slopes that are primarily less than 25%.
