A lot of people might know that Illinois-Indiana Sea Grant’s primary mission is to help protect and preserve the Southern Lake Michigan waters. But most people might not know about the many ways our program goes about doing just that.
With the help of staff members, researchers, educators, and more, we’ve produced a video that offers a glimpse at the program and the ways we work for and with the public to ensure safe waters and healthy ecosystems in both states.
Watch the video below to learn more about Illinois-Indiana Sea Grant, and share it with anyone who cares about keeping Lake Michigan healthy, beautiful, and safe.

Much of the press and media attention on the growing Asian carp threat has been focused on the Chicago canal and Lake Michigan. But that is not the only potential entryway for the invasive fish to enter the Great Lakes.
“At the top of that list of secondary pathways is an area in northern Indiana called Eagle Marsh, which separates the Mississippi basin’s Wabash River from the Maumee River basin that feeds Lake Erie. The two watersheds have a history of merging in extreme rains, so to reduce the threat of carp making the jump into Lake Erie, the federal government has erected a fence between them.”
Read the complete article linked above for more information about other potential pathways that Asian carp might take.

Last week, Illinois-Indiana Sea Grant had a two-day meeting and retreat at the
Indiana Dunes State Park in Chesterton, Indiana. In addition to devoting some time to planning and discussing current and future projects, we were treated to a couple of informative and scenic tours in the area, learning more about the extensive restoration work to protect the dunes, the state park and national lakeshore, and the water quality of Lake Michigan.
Staff members were able to join National Park Service workers on-site to learn about and get their hands dirty at the
Great Marsh Restoration Site not far from the dunes. Once very large, the remaining Great Marsh area is approximately 12 miles long and harbors a wide range of plants, animals, insects, and other beneficial organisms. Those native species are threatened by invasive species, however, and work is ongoing to plant and establish native species to bolster the wetlands’ resistance to invasive species and restore the natural balance of the area.
Informative, fun, and muddy, the chance to do on-the-ground work in restoring this watershed was a valuable experience for everyone involved, and offered a practical reminder of the importance of restoring and protecting these areas.
There are more terrific photographs of the restoration project and the lake shore on
Illinois-Indiana Sea Grant’s Facebook page. Head over and check them out, and be sure to plan a visit to the park for yourself.

With the State of Michigan taking control of a dam on the Manistique River comes an opportunity to prevent an invasive species from breeding in the river and increasing in numbers.
“That will allow the federal government to build a new barrier there to keep sea lampreys from breeding in the river. Managers of the fishery expect that will bring the lamprey problem under control in Lake Michigan.”
Read more about the plan at the article linked above.

Many educators incorporate plants and animals into their classrooms for educational purposes, but those plants and animals have the potential to become or transport invasive species to new areas.
“The study, led by Oregon Sea Grant Extension’s invasive species expert Sam Chan, was presented at this week’s national meeting of the Ecological Society of America in Portland.
‘Live organisms are a critical element for learning and we don’t want to imply that they should not be used in the classroom,’ said Chan. ‘But some of our schools – and the biological supply houses that provide their organisms – are creating a potential new pathway for non-native species to become invasive.’”

Each year, natural resource students from Purdue University, North Carolina State University, and the Swedish University of Agricultural Sciences come together to learn about sustainable use of natural resources in some part of the world. In July 2012, the course took place in the Pacific Northwest. Students visited old-growth forests, wildlife refuges, urban areas and more, learning about the political, social and economic concerns that factor into decision-making and development in the region.
Because of the partnership between Purdue University’s Department of Forestry and Natural Resources and Illinois-Indiana Sea Grant, students were able to connect with extension specialists from
Oregon Sea Grant to learn about coastal issues.

commercial fishing during a “dock walk.” |
IISG’s Carolyn Foley shares more about the course: “Amidst glorious sunshine, students learned about the strong fishing trade in Newport, OR, including oyster farming. They asked questions about how these trades are regulated in the Pacific Northwest, and what impacts their activities have on the surrounding community and natural resource use. They were also able to visit the Hatfield Marine Science Center and gain a healthy overview of the major issues affecting coastal resources in Oregon and surrounding states, including the development of technology to harness wave energy, impacts of naturally-occurring low-oxygen conditions, and effects of development on local wildlife populations. Some students even visited a large dock (~66’ x 19’ x 7’) that was ripped from its pilings in Misawa, Japan during the 2011 tsunami which crossed more than 11,000 km of Pacific Ocean and landed near Newport in early June, bringing with it more than 80 non-native, potentially invasive species of algae, snails, clams, and other life forms.”

As an amendment to the Boater Registration and Safety Act signed into law by Illinois Governor Pat Quinn, aquatic plants and animals would need to be removed from seaplanes and watercraft before moving between bodies of water. The requirement is an important step in preventing the spread of aquatic invasive species throughout the state of Illinois, as well as between states and bodies of water where these vehicles might travel.
You can read a short synopsis of the legislation from our friends at Illinois Invasive Species Awareness Month
here, and read the full text of the legislation
here.

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.
Greg holds a MS in Biology from Northern Arizona University. He joins IISG after a three-year tenure as a research assistant for the Plants of Concern Program at the Chicago Botanic Gardens.

According to some of the latest research, a population of Asian carp as small as 20 in number could be enough to establish a damaging population of the invasive species in the Great Lakes.
From The Atlantic Cities:
“The report notes that this small population would have a greater than 50 percent chance of successfully spawning if they were to find a viable river access point to the lakes. Lake Michigan is the most likely target, and the Chicago Area Waterway System of rivers, sanitary canals and locks would be the most likely entry point. Already, the environmental DNA of carp has been detected as close as six miles from Lake Michigan. Some worry that the carp’s entrance into the Great Lakes is inevitable.”
