Want to test your knowledge?

  1. Can you define the three control measures we discussed in the video?
  2. What do you think a benefit of each of the three control measures would be?
  3. What do you think a drawback of each of the three control measures would be?
  4. Which control measure would you think is best for managing waterways, if any?
  5. Draw a Water Hyacinth! On a scrape paper or in a journal, sketch out and label each anatomical structure that we reviewed in the video:
  • Roots
  • Leaf
  • Petiole
  • Mother plant
  • Daughter plant

If you would like, then share your drawings with us on social media or email our Rangers! e-mail us
