CEGL005152 Potamogeton zosteriformis - Ceratophyllum demersum - Elodea canadensis Southern Great Lakes Shore Aquatic Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Flatstem Pondweed - Coon''s-tail - Canadian Waterweed Southern Great Lakes Shore Aquatic Vegetation
Colloquial Name: Southern Great Lakes Submergent Marsh
Hierarchy Level: Association
Type Concept: 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 these 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. Dominant submerged aquatics include Ceratophyllum demersum, Chara spp., Elodea canadensis, Heteranthera dubia, Myriophyllum spicatum, Najas flexilis, Potamogeton spp. (including Potamogeton amplifolius, Potamogeton friesii, Potamogeton gramineus, Stuckenia pectinata, Potamogeton zosteriformis), and Vallisneria americana. Floating aquatics include Lemna minor, Lemna trisulca, and Spirodela polyrrhiza. Other rooted aquatics include Nymphaea odorata, Nuphar advena, Nelumbo lutea, Peltandra virginica, and Sagittaria latifolia. The exotic Hydrocharis morsus-ranae is increasingly common in St. Lawrence, Lake Ontario, and Lake Erie marshes.

Floristics: Dominant submerged aquatics include Ceratophyllum demersum, Chara spp., Elodea canadensis, Heteranthera dubia, Myriophyllum spicatum, Najas flexilis, Potamogeton spp. (including Potamogeton amplifolius, Potamogeton friesii, Potamogeton gramineus, Stuckenia pectinata (= Potamogeton pectinatus), Potamogeton zosteriformis), and Vallisneria americana. Floating aquatics include Lemna minor, Lemna trisulca, and Spirodela polyrrhiza. Other rooted aquatics include Nymphaea odorata, Nuphar advena (= Nuphar lutea ssp. advena), Nelumbo lutea, Peltandra virginica, and Sagittaria latifolia. The exotic Hydrocharis morsus-ranae is increasingly common in the St. Lawrence, Lake Ontario, and Lake Erie marshes (Minc and Albert 1998).
Dynamics: Stands appear to be correlated with greater site protection from wave action and storms (Minc 1996). The southern Great Lakes emergent marshes may have an increased level of dominance in Typha spp. because of a reduction in the amplitude of natural water-level fluctuations (Wilcox et al. 1993, in Minc and Albert 1998). It is thought that the natural fluctuations favor more diverse vegetation because they permit a wider range of habitat, exclude species that cannot tolerate water-depth changes, or favor species requiring periodic exposures of fertile substrates.
Environmental Description: 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 these 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.
Geographic Range: 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.
