Tape grass, Vallisneria americana, is a salt-tolerant freshwater SAV species that is located in the fresh, oligohaline, and mesohaline portion of estuaries in the eastern United States. Beds of tape grass can occur in the Caloosahatchee Estuary up to 30 km downstream, but grow most luxuriantly upstream of Area 3, especially where their greatest coverage occurs around Area 2 and Beautiful Island. Like other populations in Florida, tape grass in the Caloosahatchee does not completely die back in the winter as it does in more temperate northern clines. Field observations also indicate that canopy height and shoot density begin to decline as salinity rises above 10%
