Hydrilla Infestation
The introduction of non-indigenous invasive aquatic plant and animal species to the United States has been escalating with widespread destructive consequences. The impacts of the spread of invasive aquatic plants are well known: habitat disruption, degradation of native plant and animal communities, reduced shorefront property values, impaired fishing and negative impacts on recreation.
