Reference:
NatureServe Biotics 2019
Description:
This shallow, mixed emergent marsh community ranges broadly over the midwestern United States and adjacent Canada. Vegetation varies from zones dominated by tall emergents 1-2 m tall to those with hydrophytic annual and perennial forbs <1 m tall. In the tall emergent zone, <i>Schoenoplectus acutus, Bolboschoenus fluviatilis, Schoenoplectus tabernaemontani, Typha angustifolia</i>, and <i>Typha latifolia</i> may dominate, mixed with a variety of other herbaceous species such as <i>Eleocharis palustris, Juncus</i> spp., <i>Leersia oryzoides</i>, and <i>Sparganium</i> spp. In particular, <i>Bolboschoenus fluviatilis, Typha latifolia</i>, and <i>Typha angustifolia</i> sometimes form near-monocultures. The hydrophytic annual and perennial forb zone is dominated by <i>Alisma subcordatum, Alisma triviale, Sagittaria latifolia, Sparganium eurycarpum, Pontederia cordata</i>, along with <i>Bacopa rotundifolia</i> and <i>Heteranthera limosa</i>. Floating-leaved aquatics are sometimes present, including <i>Azolla caroliniana, Lemna</i> spp., <i>Spirodela polyrrhiza</i>, and <i>Utricularia macrorhiza</i>. It is found in basin-like depressions, backwater areas of floodplains, and shallow margins of lakes or ponds. Soils are shallow to deep, very poorly drained, consisting of peats, mucks, or mineral materials, often found in alluvium.
