A1708 Nuphar advena - Nuphar sagittifolia Tidal Freshwater Marsh Alliance
Type Concept Sentence: This is tidal mudflat vegetation of freshwater tidal rivers of the eastern United States dominated by species of Nuphar, including Nuphar advena or Nuphar sagittifolia.
Common (Translated Scientific) Name: Broadleaf Pond-lily - Narrowleaf Pond-lily Tidal Freshwater Marsh Alliance
Colloquial Name: Pond-lily Tidal Freshwater Marsh
Hierarchy Level: Alliance
Type Concept: These tidal mudflats of the eastern United States are dominated by species of Nuphar. Association dominants include Nuphar advena or Nuphar sagittifolia. This alliance includes vegetation of freshwater tidal rivers where the water depth is approximately 2-3 m or less. Nuphar sp. and Nymphaea odorata are dominant; these species quickly spread from their rhizomes and shade out other vegetation. Other species may include Potamogeton epihydrus, Peltandra virginica, Nymphoides cordata, and Zizania aquatica. In Delaware, this alliance occurs in nearly pure stands below mean low water on mudflats that are exposed at low tide and on the submerged point bars of stream meanders.
Diagnostic Characteristics: These are tidal freshwater wetlands, including vegetation of tidal rivers, on the mid-Atlantic Coast. Association dominants include Nuphar advena or Nuphar sagittifolia.

Concept Lineage: This alliance contains all the members of the old A.1708 (2/2). The placement of CEGL006909 here is not a good idea in my opinion (MP). It should go (back?) to G120!!
