During 1983 and 1984, information on the distribution and abundance of Hydrilla verticillata, and exotic submerged aquatic macrophyte from Sourtheast Asia, was collected in the tidal Potomac River. Data were collected on four transects established on the Virginia side of the river as well as numerous other transects established for a concurrent submersed aquatic vegetation survey. Depth of water in which Hydrilla occurred, comparative seasonal biomass, tuber production, replacement rate, and competition with other species were measured. Laboratory experiments were conducted on salinity tolerances.
