Name: Stuckenia pectinata - Myriophyllum (sibiricum, spicatum) Aquatic Vegetation Reference: NatureServe Biotics 2019 Description: This sago pondweed - water-milfoil pond community is found in glacial ponds in the northwestern Great Plains of the United States and Canada. These ponds occur at elevations ranging from 1250 to 1525 m (4100-5000 feet). Stands occur in the permanently inundated, deep water zone of glacial ponds in gently rolling, glacial terrain. Water is usually 15-100 cm deep. The type can occur in fresh to brackish water, but is characteristic of mildly brackish water. Underlying parent material is mixed sedimentary (partly calcareous) glacial till or lacustrine deposits. Pond bottoms are composed of clayey mud or mud mixed with gravel and stones. The vegetation is characteristically poor in species, and canopy cover is low to moderate, being occasionally up to 70% . Submerged aquatic macrophytes dominate the vegetation. <i>Stuckenia pectinata</i> is present in all stands sampled; <i>Myriophyllum spicatum</i> or <i>Myriophyllum sibiricum</i> can be locally dominant and was present in most stands. <i>Ranunculus aquatilis, Utricularia macrorhiza, Sagittaria cuneata</i>, and <i>Potamogeton richardsonii</i> are occasionally present. <i>Chara</i> sp., a calciphile macroalga, is often present.  Accession Code: urn:lsid:vegbank.org:commConcept:30912-{10C82EE9-50E3-4B5C-9BBD-CCEE9223E8A7} Plot-observations of this Community Concept: 2
