Description:
This wet meadow vegetation of the northeastern states is complex and variable, ranging from shrub thicket to herbaceous meadow with scattered shrubs. Shrub species usually include <i>Spiraea tomentosa, Spiraea alba var. alba, Cornus amomum, Rubus allegheniensis, Rubus hispidus, Salix</i> spp., and others. <i>Hypericum densiflorum</i> often occurs in the Central Appalachians. The invasive exotic shrubs <i>Lonicera morrowii</i> and <i>Rosa multiflora</i> may be locally abundant. Associated herbaceous species are also variable in composition, depending on land-use history. Commonly seen are <i>Calamagrostis canadensis, Carex folliculata, Carex lupulina, Carex lurida, Carex scoparia, Carex trichocarpa, Carex vulpinoidea, Eleocharis</i> spp., <i>Eupatorium maculatum, Impatiens capensis, Juncus effusus, Leersia oryzoides, Lycopus uniflorus, Onoclea sensibilis, Phalaris arundinacea, Polygonum sagittatum, Scirpus cyperinus, Scirpus expansus, Solidago canadensis, Solidago gigantea, Solidago rugosa, Thelypteris palustris, Triadenum virginicum, Vernonia noveboracensis</i>, and others. The invasive species <i>Microstegium vimineum, Lythrum salicaria</i>, and <i>Phragmites australis</i> can be abundant or form monocultures in these wetlands. Successional wet meadows in the Atlantic Coastal Plain of New Jersey can include scattered patches of <i>Liquidambar styraciflua</i> and <i>Morella pensylvanica</i>, and more predominantly grassy patches of <i>Andropogon virginicus, Panicum rigidulum, Panicum virgatum</i>, and <i>Spiraea tomentosa</i>. The alliance occurs in a variety of settings, most frequently in low-lying areas of old fields or pastures, headwater basins, or beaver-impacted wetlands.
