Name: Vallisneria americana Aquatic Vegetation Alliance
Reference: NatureServe Biotics 2019
Description: This alliance consists of aquatic vegetation in rivers and springs dominated by <i>Vallisneria americana</i>. The extent and distribution of this alliance is only partly understood. The habitat includes alluvial rivers, above or extending to the upper limit of tidal influence. Stands are dominated by submergent or emergent plants with only minor floating-leaved components. Stands in the northeastern United States may additionally contain <i>Potamogeton perfoliatus, Potamogeton epihydrus, Utricularia</i> spp., and <i>Eriocaulon aquaticum</i>. New River occurrences have <i>Elodea canadensis, Potamogeton foliosus</i>, and <i>Potamogeton nodosus</i>. In addition, <i>Heteranthera dubia</i> may be locally abundant in stands in Virginia rivers. Further study is needed to fully characterize the variability in this alliance.
