Name:
Carex torta - Apocynum cannabinum - Cyperus spp. Herbaceous Vegetation
Reference:
Eastern Ecology Working Group of...
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; they include <i>Apocynum cannabinum, Verbena hastata, Symphyotrichum puniceum (= Aster puniceus), Doellingeria umbellata (= Aster umbellatus), Solidago rugosa, Solidago canadensis, Solidago gigantea, Calamagrostis canadensis, Phalaris arundinacea, Scirpus expansus, Scirpus cyperinus, Thelypteris palustris, Scutellaria lateriflora, Agrostis stolonifera, Dichanthelium clandestinum, Eupatorium maculatum, Eupatorium perfoliatum, Elymus riparius, Cyperus strigosus</i> and other <i>Cyperus</i> spp., <i>Eleocharis</i> spp., <i>Lobelia cardinalis, Onoclea sensibilis, Viola</i> spp., <i>Clematis virginiana, Polygonum amphibium, Polygonum hydropiper, Polygonum pensylvanicum, Polygonum sagittatum, Polygonum persicaria,</i><i> Polygonum punctatum,</i><i> Polygonum lapathifolium, Schizachyrium scoparium, Andropogon gerardii</i>, and occasionally <i>Sanguisorba canadensis</i>. Battered and stunted shrubs and trees can occur, including <i>Salix sericea, Salix eriocephala, Cornus amomum, Betula nigra, Populus deltoides</i>, and <i>Platanus occidentalis</i>. Nonvascular plants can be sparse, but where present can include <i>Bryum</i> spp. Invasive, exotic species can be problematic in these areas, especially <i>Tussilago farfara, Lythrum salicaria, Polygonum cuspidatum, Polygonum persicaria</i>, and in the southern portion of the range <i>Microstegium vimineum</i>.
