18 Parrot’s Feather

19 Mathematics & Science Center Parrot’s feather can easily take over a pond. It blocks sunlight from reaching the water and reduces the amount of open water available for fish to swim.

27 Because the Chesapeake Bay watershed is so extensive, it is more vulnerable to the introduction of aquatic invasives. So what can we do to stop the spread of aliens in our area?

28 Mathematics & Science Center Ways to stop the spread of invasive aliens: Use native plants in your yard or garden. If you do use an alien plant, make sure before you plant it that it’s not highly invasive. Don’t release unwanted pets or plants into the environment. When fishing, don’t dump live bait into the water. Or use live bait that is native to the area. Clean your boat & trailer of plants or other organisms after using it. Tell other people about the problem of invasive aliens.
