    影响:
    滋扰人类: Hydrilla makes recreational activities difficult by entangling boat motors and choking swimming areas.
    竞争: Hydrilla grows tall and dense and displaces other aquatic life thereby reducing biodiversity.
    经济 /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.
