Greg Hitzroth is IISG’s new aquatic invasive species specialist, working out of the Chicago Botanic Gardens in Glencoe, Illinois. Greg will design and implement public outreach programs and resources designed to increase awareness of the spread of invasive species introduced to the waterways of Illinois and Indiana through commercial trade. He will also work closely with IISG’s Aquatic Invasive Species team to identify and partner with outside stakeholders, including suppliers of non-native species, to ensure greater public awareness of the impact of organisms in trade and strategies for reducing their movement into the Great Lakes region.

This summer, 15 Great Lakes educators swapped lesson plans for life jackets as they boarded the Lake Guardian, the U.S. Environmental Protection Agency’s research vessel, and set sail on Lake Michigan. Through the Shipboard Science Immersion program, 5–12 grade formal and non-formal educators worked side by side with Great Lakes scientists for a week—an experience they say will ripple back to their classrooms for years to come.

Last month, Illinois and Indiana educators gathered for a two-day, professional learning workshop hosted by @duneslearning, @indianadnr, @thengrrec, and Illinois-Indiana Sea Grant to dive deep into water’s role in Earth’s systems
Using @projectwet’s newest guidebook, Water in Earth Systems, participants explored the unique ecosystems of @indianadunesnps and engaged in hands-on aquatic science activities—bringing Great Lakes learning to life in the classroom!
Thanks to all who joined us in connecting science, stewardship, and the Great Lakes!
