Name: Typha spp. - Schoenoplectus acutus - Mixed Herbs Midwest Herbaceous Vegetation Reference: Midwestern Ecology Working Group... Description: This deep freshwater marsh community is found in glacial potholes, river valleys, ponds, and on lake plains throughout the midwestern and parts of the eastern United States. These marshes have hydric soils and are flooded with water levels ranging from several centimeters to more than 1 m for a significant part of the growing season. Soils that support this community can be mineral or organic but are saturated, flooded, or ponded long enough during the growing season to develop anaerobic conditions in the upper part. This deepwater emergent marsh community is dominated by perennial, coarse-leaved graminoid vegetation. A typical example of this marsh contains a mosaic of emergents, submergents, and floating-leaved plants interspersed with areas of open water. Occurrences may contain extensive areas of open water, but the vegetation covers at least 3% of the surface. Typha latifolia, Typha angustifolia, and Schoenoplectus acutus (= Scirpus acutus) dominate this dynamic ecosystem. Sedges are also common (e.g., Carex lupuliformis and Carex hyalinolepis in the eastern part of the range), and a diverse assemblage of grasses, floating-leaved aquatics, and submerged aquatics are present. Vegetative diversity and density are highly variable in response to water depth, water chemistry, and natural forces.  Accession Code: VB.CC.27236.TYPHASPPSCHOENO Plot-observations of this Community Concept: 0
