Potamogeton spp. - Ceratophyllum spp. - Elodea spp. Aquatic Vegetation
Translated Name: Pondweed species - Hornwort species - Waterweed species Aquatic Vegetation
Common Name: Pondweed - Hornwort - Waterweed Submerged Aquatic Vegetation
Unique Identifier: CEGL004725
Classification Approach: International Vegetation Classification (IVC)
Summary: This broadly defined type represents vegetation dominated by various floating-leaved and submerged aquatic species (including Potamogeton spp., Ceratophyllum spp., Utricularia spp., and Elodea spp.) from the Cumberlands across to the Atlantic and Gulf coastal plains. Individual stands are typically species-poor and may be dominated by a single species, this leading to any number of apparent dominance types. Until the patterns are better understood, these are all grouped together here.



Classification

Classification Confidence: Low - Poorly Documented
Classification Comments: Additional types may be developed as more information becomes available. Vallisneria americana may be present, and in some cases this would overlap with Vallisneria americana Aquatic Vegetation (CEGL002284).

Vegetation

Vegetation Summary: This association represents submerged aquatic vegetation in the southeastern U.S. Hydrophytes dominate the vegetation, forming 50-80% cover. Composition is variable, but typical plants include Ceratophyllum demersum, Elodea canadensis, Elodea nuttallii, Heteranthera dubia, Justicia americana, Najas gracillima, Podostemum ceratophyllum, Potamogeton crispus, Potamogeton diversifolius, Potamogeton foliosus, Potamogeton nodosus, Stuckenia pectinata (= Potamogeton pectinatus), Utricularia spp., and Vallisneria americana.

Environmental Setting

Wetland Indicator: Y
Environmental Summary: This community type is found in shallow to relatively deep (1 m) freshwater basins, marshes, or bays that remain flooded in all but the driest years. Species composition varies with substrate, water depth, water chemistry, turbidity, water temperatures and other factors, but these are poorly understood.


Dynamic Processes

Dynamics: The exotic Egeria densa may also be present and may crowd out native components. This association is reported from South Carolina by Aulbach-Smith (pers. comm. 2001).
