Description:
This herbaceous vegetation occurs on large coarse substrates deposited along medium- to high-energy river channels and, less frequently, exposed lakeshores with heavy wave action. Seasonal flooding and ice-scour maintain the open nature of these communities; generally, they develop in areas of the active channel that are exposed at low water or in drought years. Vegetation can be sparse to dense depending on degree of flooding and length of exposure. Characteristic perennial species that tolerate inundation and flood-scouring include <i>Carex torta</i> and low <i>Salix</i> spp. Associated species tend to vary widely from site to site, can be diverse, and may be sparse. Associated species vary with geography. In the Allegheny Mountains, associated species include <i>Doellingeria umbellata, Dichanthelium clandestinum, Solidago rugosa ssp. aspera, Juncus effusus var. solutus, Scirpus expansus, Scirpus cyperinus, Equisetum arvense, Onoclea sensibilis, Vernonia noveboracensis, Lycopus virginicus, Scutellaria lateriflora</i>, and <i>Salix sericea</i>. In Southern Appalachian gorges, this vegetation often is associated with ~<i>Alnus serrulata - Xanthorhiza simplicissima</i> Wet Shrubland (CEGL003895)$$. In the Cumberland Plateau of Alabama, herbaceous components may include <i>Lobelia cardinalis, Symphyotrichum dumosum, Lycopus virginicus, Osmunda regalis</i>, and <i>Hypericum mutilum</i>. Physiognomy varies from strictly herbaceous to shrubby to wooded herbaceous. Scattered shrubs and small, battered specimens of <i>Platanus occidentalis, Betula nigra, Cornus amomum, Alnus serrulata</i>, and <i>Carpinus caroliniana</i> are present in some stands. Stands in disturbed landscapes may be heavily invaded by <i>Microstegium vimineum, Polygonum cespitosum var. longisetum</i>, and other weedy exotics.
