Name: Cephalanthus occidentalis - Decodon verticillatus Shrub Swamp Alliance
Reference: NatureServe Biotics 2019
Description: The alliance is wide-ranging, throughout glaciated regions of the midwestern and northeastern United States and adjacent Canada. The vegetation is characterized by <i>Cephalanthus occidentalis</i> or <i>Decodon verticillatus</i> and occurs in depressions, oxbow ponds, and backwater sloughs of stream and river floodplains in waters 1-2 m deep. Occasional shrub associates include any number of <i>Salix</i> spp. or <i>Cornus</i> spp., as well as <i>Ilex verticillata, Rosa palustris, Vaccinium corymbosum</i>, and <i>Viburnum dentatum</i>. Floating aquatics, such as <i>Lemna</i> spp., can be common in deepwater habitats, whereas a variety of forbs and graminoids are associates under less flooded conditions. These include <i>Bidens tripartita, Boehmeria cylindrica, Glyceria</i> spp., <i>Leersia oryzoides, Polygonum</i> spp., <i>Scutellaria lateriflora, Sium suave</i>, and a wide variety of <i>Carex</i> spp. Inundation is usually continuous throughout the year, but these sites can become dry in mid or late summer or during periods of prolonged drought.
