Name: Potamogeton richardsonii Permanently Flooded Herbaceous Alliance Reference: Western Ecology Working Group of... Description: This alliance is found in still, shallow to moderately deep water of ponds and lakes in the northwestern Great Plains. Associations occur in the permanently inundated, 'deep water' zone of glacial ponds in gentle, rolling, glacial terrain. The underlying parent material is mixed sedimentary (partly calcareous) glacial till. Pond bottoms are typically composed of mud, organic mud, or mud mixed with gravel and stones. All examples are dominated by aquatic macrophytes. Potamogeton richardsonii is the most prominent and conspicuous plant due to its broad leaves. It dominates the forb layer with up to 50% cover. Other aquatic associates can include Utricularia macrorhiza (= Utricularia vulgaris), Potamogeton gramineus, Ranunculus aquatilis, Myriophyllum spicatum, and Polygonum amphibium.  Accession Code: VB.CC.20449.POTAMOGETONRICH Plot-observations of this Community Concept: 0
