Invasive species, as you probably know, can have devastating effects when they take hold. They can negatively impact, and in some cases permanently alter, entire ecosystems, disrupting industry and tourism, and affecting home and business owners near those areas.
With summer on the way, there’s no better time than now to spread the word about invasive species and how we can stop them. And that is why May is Illinois Invasive Species Awareness Month.
Now is the perfect time to get people involved in the work of preventing the damage they can do right here in Illinois.
In addition to the links above, don’t forget to visit our Clean Boats, Clean Waters web page for simple and useful ways that boaters can join in the fight to prevent invasive species from spreading. You can also find information on how to volunteer for our Clean Boats Crew and provide in-person advice and tips at local boat ramps and marina.
Following up on our post from March 12, Caitie McCoy and Terri Hallesy visited with students in East Chicago to see how their projects studying the Roxana Marsh area were going. Terri sent along some details:
On April 19, Caitie McCoy invited Education Specialist Terri Hallesy, to visit Andrea Bock’s 4
th grade science classrooms at East Chicago Lighthouse Charter School. The students have been learning about the Great Lakes Legacy Act cleanup project at Roxana Marsh and how to design a habitat. Jack Brunner, an EPA contractor whose employees work on-site at Roxana Marsh, was invited as a guest speaker to share his restoration work with the students. Caitie McCoy and colleague, Nishaat Yunus, actively engaged students in a discussion about key concepts associated with habitats and restoration projects. Students participated in a hands-on activity to design their own Roxana Marsh habitat by constructing a colorful classroom mural. Students were divided into groups and provided with photos depicting various elements contained within a habitat. Selected photos included nonliving elements, such as the sun and oxygen; above water living plants like black-eyed Susan and wild bergamot; and above water living animals such as the great blue heron and Peregrine falcon. Using various art tools, students designed and illustrated some of the components that comprise the Roxana Marsh habitat. Caitie McCoy and Terri Hallesy affixed the students’ creative illustrations onto a mural, which is now proudly displayed in their classroom. As a culminating event, Jack Brunner surprised the students by presenting a painted turtle that was found on the Roxana Marsh site and has been kept as a pet during the cleanup. The next step in this exciting restoration project will involve the students actually visiting Roxana Marsh to plant natives they’ve been cultivating in their classroom.
All of the students had a great time getting involved and learning about the marsh, and they’re looking forward to planting the native species they’ve been growing in the class.
The term “food web” is used to describe the intricate relationships between the many different plants, animals, and organisms that can exist in small or large areas. Understanding food webs in specific environmental locations, such as in one or more of the Great Lakes, can help researchers and communities better respond to changes in those delicate systems. Invasive species are just one example of a potential influence that can drastically alter a food web and have substantial impacts on native environments.
On April 3 and 4, 2012, Illinois-Indiana Sea Grant (IISG) and GLRRIN Lake Michigan
partners from Wisconsin Sea Grant(WISG), Michigan Sea Grant, the NOAA Great Lakes Environmental Research Laboratory, the US EPA Great Lakes National Program Office, and the USGS Great Lakes Science Center hosted a research meeting in Ann Arbor, MI. Approximately 60 researchers from federal, state, university, tribal, and non-profit organizations gathered to discuss their current understanding of food webs in Lake Michigan. Food web structure and function can be affected by many variables, including changes in water temperature, water quality, and/or habitat loss. Recent aquatic invaders, including zebra and quagga mussels, have drastically altered the Lake Michigan ecosystem, leaving researchers with new questions about what variables most affect commercial and recreational fishing, bird populations, non-toxic algal blooms, and overall quality of life for humans and animals.
GLRRIN Lake Michigan hosted a similar meeting in 2008, which helped launch the 2010 Lake Michigan Intensive Monitoring Field Year. Findings presented during the 2012 meeting highlight the inherent variability of Lake Michigan, especially in areas that are less than 20 m deep. Researchers also stressed the need to further understand how the lowest levels of the food chain, such as microbes and nutrient cycling, operate. Understanding these basic levels will help create better tools for decision makers like fishery managers or watershed planning committees. A full report on the meeting presentations and discussions will be made available through the GLRRIN Lake Michigan and IISG websites.
