This acidic deciduous swamp occurs in the central Appalachian Mountains north of the Cumberland drainage in the Central Appalachians and High Allegheny regions, as well as the adjacent Cumberlands and Western Allegheny Plateau. This community occurs on substrates which are saturated for extended periods during the growing season but which rarely have standing water, including forested seeps, hillsides, streamheads, floodplain edges, and poorly drained depressions. Occurrences tend to be small. Characteristic trees are <i>Acer rubrum</i> and <i>Nyssa sylvatica</i>, with other associates including <i>Tsuga canadensis</i> and <i>Betula alleghaniensis</i>. The shrub stratum includes <i>Alnus serrulata, Photinia pyrifolia (= Aronia arbutifolia), Ilex verticillata, Vaccinium corymbosum, Rhododendron maximum</i>, and <i>Rubus hispidus</i>. Characteristic herbs include <i>Osmunda cinnamomea, Osmunda regalis, Carex folliculata, Carex trisperma, Carex intumescens, Carex stricta</i>, and <i>Poa trivialis</i>. <i>Sphagnum</i> spp. are typical. |

This dry, acidic oak woodland occurs on rocky upper slopes and summits from New England south to the highest peaks in West Virginia. Typical settings are low- to mid-elevation summits and south-facing, upper slopes. Elevations of known occurrences range from near sea level to about 610 m (0-2000 feet) in New England, and to 1370 m (4500 feet) in West Virginia. Soils are shallow, well-drained, acidic, nutrient-poor gravels and coarse sands, often with prominent exposed bedrock. Canopy cover is variable, ranging from open and patchy to closed depending on site conditions. It overtops a dwarf-shrub layer that is frequently extensive and a sparse tall-shrub layer. Herb cover is patchy and variable. Bryoid cover is minor, scattered patches on the rocky substrate. The canopy is dominated by scattered, often stunted <i>Quercus rubra</i> with minor associates depending on geography and often including <i>Quercus velutina, Quercus prinus, Betula populifolia, Betula papyrifera, Betula lenta</i>, and <i>Acer rubrum</i> or <i>Quercus coccinea</i> in more coastal regions. <i>Quercus rubra</i> tends to be the only oak at the northern end of the range. <i>Pinus strobus, Pinus rigida</i>, or other conifers may be present, but only in minor amounts. The dwarf-shrub layer is strongly dominated by heaths, especially <i>Vaccinium angustifolium, Vaccinium pallidum, Vaccinium myrtilloides</i>, and <i>Gaylussacia baccata</i> with <i>Gaylussacia frondosa, Comptonia peregrina</i>, and <i>Kalmia angustifolia</i> also common. Tall shrubs may include <i>Quercus ilicifolia, Hamamelis virginiana, Amelanchier</i> spp., and <i>Prunus pensylvanica</i>. The herbaceous layer is comprised of <i>Deschampsia flexuosa, Danthonia spicata, Carex lucorum, Pteridium aquilinum, Comandra umbellata, Melampyrum lineare, Polygala paucifolia, Epigaea repens, Gaultheria procumbens</i>, and <i>Aralia nudicaulis</i>. The bryophyte layer includes <i>Polytrichum commune, Leucobryum glaucum</i>, and others. |

These are silver maple floodplain forests along major rivers in the temperate northeastern United States. They occur on the deep, alluvial, silty to somewhat coarse soils of point bars, levees, and adjacent terraces of medium to large, high-energy and moderate-gradient rivers with heavy erosion and sedimentation, and are subjected to spring flooding. The more-or-less closed canopy is high and arching, and the dominant below-canopy feature is the lush and extensive herb layer, with ferns especially prominent. Shrubs are scattered and the overall shrub cover is low. Bryoids are very minor. The canopy is strongly dominated by <i>Acer saccharinum</i>. Other trees may be locally common, or scattered, including <i>Populus deltoides, Quercus rubra, Acer negundo, Ulmus rubra, Juglans nigra, Fraxinus americana</i>, and <i>Fraxinus pennsylvanica</i>. <i>Populus deltoides</i> tends to be characteristic of the siltier soils and levees within these forests. Typical shrubs include <i>Lindera benzoin, Cornus amomum, Sambucus canadensis</i>, and potentially invasive non-native <i>Lonicera</i> spp., <i>Rosa multiflora</i>, or <i>Ligustrum vulgare</i>. Vines such as <i>Vitis riparia</i> are common at some sites. The dominant herbs are <i>Matteuccia struthiopteris</i> and <i>Laportea canadensis</i>. Associated herbs include <i>Elymus riparius, Elymus virginicus, Amphicarpaea bracteata, Ageratina altissima (= Eupatorium rugosum), Arisaema triphyllum, Circaea lutetiana, Thalictrum pubescens, Onoclea sensibilis</i>, and <i>Polygonum virginianum (= Tovara virginiana)</i>. Particularly in the southern portions of this type's range, non-native herbs such as <i>Alliaria petiolata, Allium vineale, Ranunculus ficaria</i>, and <i>Microstegium vimineum</i> may essentially replace the native herbs. This association is distinguished from the related ~<i>Acer saccharinum / Onoclea sensibilis - Boehmeria cylindrica</i> Forest (CEGL006176)$$ by its greater abundance of <i>Matteuccia struthiopteris</i> relative to <i>Onoclea sensibilis</i> and its better-drained soils. Flood duration is usually shorter in the ostrich fern type. It is distinguished from floodplain forests to the south by the absence (or only very rare presence) of <i>Platanus occidentalis</i> and <i>Celtis occidentalis</i>. |
