Unexpected Guests

Are non-native species beneficial or harmful? WILD Aquatic’s activity “Aquatic Roots” explores this question by looking at local non-native plants and animals. Check out a short list of exotic species found in Iowa.

Extend this activity into a service learning project by contacting a local public area and asking if they need help removing exotic invasive plants (garlic mustard, Japanese bamboo, etc.) from their boundaries. Chances are your call will be more than welcomed!

Want to see the positive effects from exotic species? Contact a local fish hatchery and ask for information about the DNR’s stocking program; specifically the species of trout the State stocks. For more information visit the hatcheries page on the DNR's website.
