Name: Leersia oryzoides - Sagittaria latifolia Herbaceous Vegetation
Reference: Eastern Ecology Working Group of...
Description: 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, Eupatorium 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.
