Name: Andropogon gerardii - Panicum virgatum - Helianthus grosseserratus Wet Meadow Reference: NatureServe Biotics 2019 Description: This wet-mesic tallgrass prairie community is found widely throughout the central midwestern United States. Stands typically occur in narrow draws of headwaters of small streams, depressions of terraces (sometimes uplands), and on floodplains of larger streams and rivers. The loamy soils are somewhat poorly drained and deep (100 cm or more). Standing surface water may be present for short periods in the winter and spring or after heavy rains. Fire was common in this community. There is a single layer of dominant graminoids intermixed with abundant forbs. <i>Andropogon gerardii</i> and <i>Spartina pectinata</i> can exceed 2 m in height in this wet-mesic community. <i>Panicum virgatum</i> is usually somewhat shorter but still greater than 1 m tall. Other typical plants found in this community in Missouri are <i>Juncus interior, Tripsacum dactyloides, Helianthus grosseserratus, Potentilla simplex, Eryngium yuccifolium</i>, and <i>Carex bicknellii</i>. <i>Calamagrostis canadensis</i> is more common northward. Species diversity does not tend to be as high as in more mesic grassland communities. Woody species can become more abundant in the absence of fire.  Accession Code: urn:lsid:vegbank.org:commConcept:30933-{34C908F2-C98F-40A6-90F7-47B44340BAEE} Plot-observations of this Community Concept: 0
