The original monster weed!


Tree of Heaven Ailanthus altissima

appearance of many smaller plants around

the base of the original invader.

and reduces the amount of open water available for fish to swim.

Because the Chesapeake Bay watershed is so extensive, it is more vulnerable to theintroduction of aquatic invasives.

So what can we do to stop the spread of aliens in our area?


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 uselive 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.
