A4064 Nymphaea odorata - Nuphar spp. - Brasenia schreberi Aquatic Vegetation Alliance

Type Concept Sentence: This submerged aquatic alliance, common throughout most of the eastern and central United States and adjacent Canadian provinces, is dominated by hydromorphic-rooted aquatic plants, typically Brasenia schreberi, Nuphar spp., Nymphaea odorata, and Nymphoides aquatica. It may occur in a variety of slow-moving waterbodies, including rivers, millponds, streams, shallow ponds or lakes, or on shores of deeper waterbodies including freshwater tidal areas.


Common (Translated Scientific) Name: American White Water-lily - Pond-lily species - Watershield Aquatic Vegetation Alliance

Colloquial Name: Water-lily - Pond-lily Aquatic Vegetation

Hierarchy Level:  Alliance

Type Concept: This alliance, common throughout most of the eastern and central United States and adjacent Canadian provinces, contains vegetation which may occur in a variety of slow-moving waterbodies, including rivers, millponds, streams, shallow ponds or lakes, or on shores of deeper waterbodies including freshwater tidal areas. Stands are dominated by hydromorphic-rooted aquatic plants, typically Nuphar spp., with or without Nymphaea odorata and Nymphoides aquatica. Emergent vegetation is less than 25%, and typically plant species diversity is low. Other species present may include Utricularia spp., Potamogeton spp., and others. In the north, Brasenia schreberi may be locally dominant. Other characteristic northern species include Nymphaea tetragona and Potamogeton amplifolius. Associates found in the Midwest include Polygonum amphibium. Stands of this alliance are permanently to semipermanently flooded, and water depth is generally greater than 0.5 m and up to 2 m.

Diagnostic Characteristics: This alliance is characterized by permanently flooded, low water energy wetlands dominated by Nuphar spp., Nymphaea odorata, Brasenia schreberi, and Nymphoides aquatica.

Physiognomy and Structure: This alliance consists of communities dominated by floating, rooted aquatic forbs. Typically these forbs have broad, flat leaves attached to elongated stems, allowing them to float on the water surface. Cover of the water surface by these forbs is variable, from somewhat sparse to very dense.

Floristics: Stands are dominated by hydromorphic-rooted aquatic plants, typically Nuphar spp. (any of the North American taxa), with or without Nymphaea odorata. Emergent vegetation is less than 25%, and typically plant species diversity is low. Other species present may include Utricularia spp., Potamogeton spp., and others. In the north, Brasenia schreberi may be locally dominant. Other characteristic northern species include Nymphaea tetragona and Potamogeton amplifolius (Harris et al. 1996). Associates found in the Midwest include Polygonum amphibium. In the Southeast, examples may include the floating or emergent "pad-leaved" species Nelumbo lutea or Nymphoides aquatica. Submerged aquatic species which may be present include Cabomba caroliniana, Ceratophyllum demersum, and Heteranthera dubia.
