Description:
The vegetation of this alliance is characterized by dense stands of graminoids 1-2 m tall with scattered to very infrequent woody plants. <i>Spartina pectinata</i> and <i>Calamagrostis canadensis</i> are typically the two most common species with <i>Spartina pectinata</i> sometimes forming near monocultures. Shrubs, particularly <i>Salix discolor, Salix petiolaris</i>, and <i>Betula pumila</i>, can be common in some stands in the northern part of this alliance's range. Other common species are <i>Carex aquatilis, Carex atherodes, Carex pellita</i>, and <i>Carex sartwellii</i>. Species typical of mesic prairies can be present, including <i>Andropogon gerardii, Muhlenbergia richardsonis, Panicum virgatum</i>, and <i>Sorghastrum nutans</i>. Forbs can be abundant and include <i>Helianthus grosseserratus, Lythrum alatum, Pycnanthemum virginianum, Symphyotrichum ericoides, Symphyotrichum novae-angliae</i>, and <i>Thalictrum dasycarpum</i>. Shrubs and small trees are often present. Among these <i>Cornus</i> spp., <i>Fraxinus pennsylvanica</i>, and <i>Salix</i> spp. are typical. This alliance is found primarily in central North America. Stands of this wide-ranging alliance are found on level to gently sloping sites with sand, loam, or clay soils. They occur near lakes or rivers or in depressions. All sites are typically flooded for part of the winter and spring and usually remain saturated for much of the growing season.
