Name: Ceratophyllum demersum - Vallisneria americana - Najas spp. Tidal Herbaceous Vegetation
Reference: Eastern Ecology Working Group of...
Description: This association comprises mixed freshwater subtidal aquatic beds of the mid-Atlantic coast. It occurs in fresh reaches of upper bays and tributaries within estuarine systems. Species composition is variable and includes Vallisneria americana, Ceratophyllum demersum, Heteranthera dubia, Elodea canadensis, Najas guadalupensis, Najas gracillima, Najas minor, Potamogeton pusillus, and others. There is often a strong component of exotic species that can be locally or extensively dominant including Myriophyllum spicatum, Hydrilla verticillata, and Potamogeton crispus, which may be indicative of poorer water quality. This association can have dramatic seasonal fluctuations in species composition and biomass.
