    影響：
    滋擾人類: Hydrilla makes recreational activities difficult by entangling boat motors and choking swimming areas.
    競爭: Hydrilla grows tall and dense and displaces other aquatic life thereby reducing biodiversity.
    經濟 /民生: 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.
