“Plant species were chosen based on the results of a risk assessment tool developed in Indiana by the Aquatic Plant Working Group. The tool evaluates species based on factors like ability to thrive in the Great Lakes and difficulty to control. At the request of Indiana Department of Natural Resources, Illinois-Indiana Sea Grant organized and facilitated the group, which included representatives from the aquatic plant industry, aquarium and water garden hobbyists, state agencies, academia, and non-governmental organizations. Their efforts led to a rule approved last year that bans the sale of 28 invasive aquatic plants in Indiana.‘It is important to have consistent regulations across the Great Lakes Basin. We want our policies to be consistent with our neighbors since invasive species don’t respect political boundaries,’ said Kevin Irons, aquaculture and aquatic nuisance species program manager for Illinois DNR. ‘Prevention is the first and cheapest way to protect Illinois from aquatic invasive plants, and risk assessment tools like the one built in Indiana allow us to identify and control high risk species without unduly regulating the industry.'”

To every educator who has brought the Great Lakes into their classroom, thank you. 🍎
Your curiosity is contagious. Your lessons last. And the students who learn to love these waters? They’ll protect them.
