CEGL006431 Elodea canadensis - Potamogeton spp. Eastern Aquatic Vegetation
Type Concept Sentence: No Data Available
Common (Translated Scientific) Name: Canadian Waterweed - Pondweed species Eastern Aquatic Vegetation
Colloquial Name: Eastern Waterweed - Pondweed Aquatic Vegetation
Hierarchy Level: Association
Type Concept: This is a broadly conceived type that encompasses northeastern aquatic vegetation found in higher pH waters. The dominants are usually submerged macrophytes or floating-leaved pondweeds. Indicator species include Elodea canadensis, Potamogeton robbinsii, Potamogeton vaseyi, Stuckenia filiformis, Potamogeton friesii, and Potamogeton strictifolius. Vallisneria americana is often present. Nymphaea odorata and Nuphar spp. are often present but are not abundant. This vegetation is found in quiet waters at 0.5-2 m depth. In Maine, alkalinity is relatively high for ponds of the glaciated Northeast, with conductivity readings usually exceeding 50 uMHOs/cm. More intensive sampling that extends over a broader geographic range is needed to determine if particular associations within this concept should be segregated.
Diagnostic Characteristics: No Data Available
Rationale for Nominal Species or Physiognomic Features: No Data Available
Classification Comments: In error, the Maine type forming the basis for this was originally cross-referenced to ~Potamogeton spp. - Ceratophyllum demersum - Crassula aquatica Aquatic Vegetation (CEGL006340)$$; that is incorrect as that type is a freshwater tidal association.
