“Under mostly sunny skies and temperatures hovering near 30 degrees, a three-man crew from the U.S. Fish and Wildlife Service and the DNR motored across the bay in a flat-bottomed boat looking for promising sites to sample.A scientist at the University of Notre Dame pioneered the technique of using DNA to search for populations of Asian carp. But the first step is far from rocket science:One member of the crew stretched in a nearly prone position over the side of the boat and dipped a 2-liter plastic bottle into the 40-degree water. The driver read out GPS coordinates, the water temperature and the depth. The third man from the crew scribbled down the information.The samples are processed in Green Bay and then packed with dry ice and sent to a Fish and Wildlife Service laboratory in La Crosse, where the DNA sequencing is done and water is matched with known DNA specimens of the two carp species. The samples will be queued up with hundreds of other potential carp samples from Illinois and elsewhere.”

In the news: Biologists take samples in Sturgeon Bay searching for Asian carp evidence
November 14th, 2013 by Irene MilesIn the news: Asian carp DNA found in Lake Michigan water for the first time
November 5th, 2013 by Irene MilesA recent article in the Journal-Sentinel online reports that Asian carp DNA have been found for the first time in the Lake Michigan waters near Wisconsin.
From JSonline:
“The single positive water sample for the jumping silver carp was taken May 31 in Sturgeon Bay near Door County’s Potawatomi State Park.
The sampling was part of a Lake Michigan-wide survey looking for evidence of Eurasian ruffe, a different type of invasive fish species. The water sample was not screened for the presence of Asian carp DNA until this fall, and the DNR did not get word of the positive result until last week, said Mike Staggs, DNR’s fishery director.
The sample was the only positive found among the 282 water samples taken from Wisconsin’s Lake Michigan waters this year as part of an invasive fish survey conducted by government crews and researchers from the University of Notre Dame and The Nature Conservancy. Fifty of those of samples were taken in the Sturgeon Bay area.Nobody is sure at this point what to make of this single piece of microscopic evidence.
There are several potential sources for the genetic scraps, including boat hulls, bird feces, or contaminated bait buckets. It could, of course, also signal the presence of a live fish.”
Great Lakes video informs Congressional legislation

In addition to reauthorizing the Great Lakes Legacy Act, which provides support for communities to clean up waterways that are designated Areas of Concern (AOC) the United States and Canada, the new legislation would continue funding the Great Lakes Restoration Initiative and the EPA Great Lakes National Program Office.

The 12 days of A.I.S.-mas
December 21st, 2012 by Irene MilesMaking a Great Lakes-themed riff on a holiday classic, the Milwaukee Journal Sentinel has compiled some aquatic invasive species information in the form of a modified “Twelve Days of Christmas.”
Seven carp a-leaping, perhaps? Check out the full article, written by our friends at Wisconsin Sea Grant, and learn a little more about aquatic invasives in the process.
From everyone at Illinois-Indiana Sea Grant, have a safe, happy, and healthy holiday season.
Wisconsin students learn about Great Lakes cleanup
December 10th, 2012 by Irene MilesCaitie writes, “I visited Sheboygan, Wisconsin last Tuesday and spoke to high school biology students, answering questions about the Great Lakes Legacy Act dredging project happening just two miles from their school. This was my final school to visit in Sheboygan as part of a 12-school, countywide tour, which began this past October and reached about 600 high school science students. Now the students know the purpose of a cleanup happening right in their downtown, and they understand the science behind it.

This project is part of a larger effort to provide students with stewardship opportunities and supplemental hands-on education about remediation and restoration efforts throughout the Great Lakes. It has been great to work with students in Sheboygan and Northwest Indiana, and I look forward to bringing this program to more Great Lakes students soon.”
2012 Chicago Wilderness Conference brings together environmental organizations
November 20th, 2012 by Irene Miles
Last week, representatives from over 260 member organizations, students, educators, were joined by Illinois-Indiana Sea Grant staff at the Chicago Wilderness Congress 2012. The overall theme of the congress was “Shaping the Future of Regional Conservation,” and numerous presentations and panels offered information on green infrastructure, climate action, research, restoration, and more. 600 attendees from northeastern Illinois, northwest Indiana, and southeast Wisconsin helped make the event exciting and educational, bringing in examples of their conservation and environmental work.At the congress, Illinois-Indiana Sea Grant was also able to exhibit several education and outreach projects focused on community stewardship, including aquatic invasive species, proper pharmaceutical disposal, and habitat restoration, as well as program initiatives and accomplishments.
IISG’s Kristin TePas summed up the event by saying, “The Chicago Wilderness Congress was a great opportunity to connect with conservation practitioners in the Chicago region and to learn about the various projects occurring locally.”
You can read more about the conference, including detailed presentation descriptions, at the Chicago Wilderness website.
In the news: Great Lakes Restoration Initiative funds help in the fight against invasive plants
October 12th, 2012 by Irene Miles“This quest received a financial boost last week when the U.S. Environmental Protection Agency awarded a $448,663 Great Lakes Restoration Initiative grant to the Ozaukee Washington Land Trust. In return, the group and its partners will inventory and eliminate the most aggressive of invasive plants in wetlands and waterways in the six counties.Graff, executive director of the land trust, said work will continue the rest of this year on locating each infestation. The organization is working with other land trusts in the region, the Wisconsin Land and Water Conservation Association and River Alliance of Wisconsin to curb the threat posed by the exotic plants.”

Coastal protection is not limited to concrete, rocks, and steel. Coastal protection solutions exist on a spectrum, ranging from softer “green” solutions to harder “gray” structures.
Nature-based coastal solutions fall between green and gray techniques, providing multiple benefits to people and habitats.
Our three-part video series, Nature-Based Coastal Solutions in the Great Lakes, is now available to watch. Learn how nature-based coastal solutions, including nature-driven and hybrid approaches, can protect shorelines while supporting ecosystems and communities.
