CEGL002044 Potamogeton spp. - Ceratophyllum demersum Great Plains Aquatic Vegetation

Type Concept Sentence: No Data Available


Common (Translated Scientific) Name: Pondweed species - Coon''s-tail Great Plains Aquatic Vegetation

Colloquial Name: Great Plains Pondweed Submerged Aquatic Wetland

Hierarchy Level:  Association

Type Concept: This community type is found in the Great Plains of the United States in shallow to relatively deep (1 m) freshwater basins or bands in marshes or bays that remain flooded in all but the driest years. Vegetation varies from sparse to dense, with submersed rooted and free-floating macrophytes. Species composition varies with substrate, water depth, water chemistry, turbidity, water temperatures and other factors, but these are poorly understood. Dominant species in Nebraska include narrow-leaved pondweeds (Potamogeton foliosus, Stuckenia pectinata, Potamogeton pusillus), Najas guadalupensis, and Zannichellia palustris. Ceratophyllum demersum and Utricularia macrorhiza can be locally abundant. In quiet bays, Potamogeton nodosus and Lemna spp. are common. In clear water with sandy bottoms Chara spp. may also be common.

Classification Comments: This type is geographically restricted to the interior Great Plains (Province 331 and 332 of Bailey et al. 1994) until a better understanding of its floristic composition and relation to Midwest pondweed types can be determined. However, it may be absent from western Kansas (sections 331B, 331C). In Nebraska, both the pondweed wetland (deep marsh) and the Sandhills deep marsh are treated together here until further investigation can resolve the distinctiveness of the sandhills type. Steinauer and Rolfsmeier (2003) suggest that the Sandhills deep marsh differs in that it contains a more organic substrate and is dominated by broad-leaved pondweeds (Potamogeton pusillus, Potamogeton richardsonii, Potamogeton zosteriformis); otherwise species composition is similar.

Floristics: Vegetation varies from sparse to dense, with submersed rooted and free-floating macrophytes. Species composition varies with a number of environmental factors, such as substrate, water depth, and water chemistry, but these are poorly understood. Dominant species in Nebraska include narrow-leaved pondweeds (Potamogeton foliosus, Stuckenia pectinata (= Potamogeton pectinatus), Potamogeton pusillus), Najas guadalupensis, and Zannichellia palustris. Ceratophyllum demersum and Utricularia macrorhiza can be locally abundant. In quiet bays, Potamogeton nodosus and Lemna spp. are common. In clear water with sandy bottoms Chara spp. may also be common. Azolla caroliniana and the liverworts Riccia fluitans and Ricciocarpos natans may also be common. Uncommon species present in this community include Nuphar sp. (e.g., Nuphar pumila, Nuphar variegata), Nymphaea odorata, and Potamogeton amplifolius (Steinauer and Rolfsmeier 2003). Other species can include Schoenoplectus spp. (= Scirpus spp.) and Typha spp.
