Benefits From an Exotic Species of Submerged Aquatic Vegetation
Found to produce vegetation masses dense enough to impede boat traffic and water sports in some areas, it was feared that hydrilla's spread would eliminate native SAV, and have an adverse effect on waterfowl, such as black duck, and on fish, and crabs in the tidal Potomac.

They recorded the percentage of total coverage and biomass of each species attained annually and discovered that, hydrilla was always more than 40% of the total abundance of vegetation but did not eliminate other species over the 17-year period of study. They found the percent of native SAV increased over time. Results indicated that as nitrogen concentration decreased, diversity of vegetation increased. In addition, they compared abundance of waterfowl between periods when there was no SAV and periods when exotic species of SAV were dominant. They found a positive response by waterfowl to vegetation communities dominated by exotic SAV.

Algaecide Treatments Not Effective on Starry Stonewort - New research findings from MAISRC show that algaecide treatments that targeted starry stonewort reduced its biomass, but failed to kill — and may have even increased the abundance of — bulbils, the alga’s primary means of reproduction.
