Classification of Vegetation Communities of Maryland: First Iteration

V. HERBACEOUS VEGETATION
V.C.2.N.a. Permanently flooded temperate or subpolar hydromorphic rooted vegetation
V.C.2.N.a.102. NYMPHAEA ODORATA - NUPHAR SPP. PERMANENTLY FLOODED TEMPERATE HERBACEOUS ALLIANCE
White Water-lily - Yellow Pond-lily species Permanently Flooded Temperate Herbaceous Alliance

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 water bodies, including rivers, millponds, blackwater rivers, streams, shallow ponds or lakes, or on shores of deeper water bodies including freshwater tidal areas. The water depth is generally greater than 0.5 m and up to 2 m. Stands are dominated by hydromorphic rooted aquatic plants, typically Nuphar lutea (any of its various subspecies), 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. 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. Stands of this alliance are permanently to semipermanently flooded.

Comments: Field guidelines for separating floating-leaved aquatic alliances from submerged aquatic alliances are also needed.

Range: This alliance is common throughout most of the eastern and central United States and adjacent Canadian provinces. It is also found in Oregon, Washington, California, Idaho, Colorado, and possibly Wyoming (?).
