• Various control methods have been used to combat the spread of invasive plant species

  • Chemical control methods have pros and cons

    • Quick treatment, but costly and can have negative impacts on native plants and animals

  • Biological control methods can alter fish habitat and limit the growth of invasive plants

    • Species-specific insects can be effective, but may take several years to show results
