    Impacts:
    Competition: Hydrilla grows tall and dense and displaces other aquatic life thereby reducing biodiversity.
    Economic/Livelihoods: Overabundant Hydrilla makes it difficult for fish to find their prey, causing a decline in valuable sport fisheries. Recreational areas lose visitors and their associated monetary spending when Hydrilla clogs boat motors and entangles swimmers.
    Human nuisance: Hydrilla makes recreational activities difficult by entangling boat motors and choking swimming areas.
