Name: Typha spp. - Schoenoplectus tabernaemontani - Mixed Herbs Southern Great Lakes Shore Herbaceous Vegetation Reference: Midwestern Ecology Working Group... Description: This deep emergent marsh community typically occurs in the southern Great Lakes region of the United States and Canada, including southern Lake Michigan, Lake St. Clair, Lake Erie, Lake Ontario, and into the St. Lawrence River, and possibly Lake Champlain. Remaining stands in the area are primarily found in lacustrine estuaries, barrier-beach lagoons, or sand-spit swales. In the Great Lakes the estuaries are often formed at the mouths of rivers drowned by the post-glacial rise in lake level, whereas in the St. Lawrence River the estuaries are formed from small streams or rivers that occupy apparent pre-glacial valleys that have been partly filled in by outwash and alluvial deposits to form fairly broad, flat basins. Storms, seiches, and water level cycles create a very dynamic pattern of species composition and structure in the vegetation. Water depth generally exceeds 0.3 m. Typical dominants include the emergents <i>Schoenoplectus tabernaemontani (= Scirpus tabernaemontani)</i> and <i>Typha</i> spp. (<i>Typha angustifolia, Typha x glauca, Typha latifolia</i>). Stands in Lake Erie and Lake Ontario may contain more pure <i>Typha angustifolia</i> stands, or mixes of that species with <i>Calamagrostis canadensis</i>. <i>Thelypteris palustris</i> is a common fern. <i>Impatiens capensis</i> may be common in open parts of the marsh. Floating and rooted aquatics include <i>Ceratophyllum demersum, Lemna minor, Nuphar advena (= Nuphar lutea ssp. advena), Nymphaea odorata, Potamogeton gramineus, Sagittaria latifolia</i>, and <i>Spirodela polyrrhiza</i>.  Accession Code: VB.CC.36759.CEGL005112 Plot-observations of this Community Concept: 0
