“Be A Hero” is now the primary invasive species awareness campaign in Illinois. Boaters, anglers, and divers have heard this message, but now the comprehensive campaign provides easy tips to help water gardeners, teachers and aquarium hobbyists curb the spread of aquatic invaders. Plus, Be A Hero also provides guidance to hunters, campers and hikers to prevent the spread of species that threaten habitats on land.

“Be A Hero” is the invasive species prevention message in Illinois
October 27th, 2015 by iisg_superadminWhat would the Great Lakes look like without invasive species?
May 26th, 2015 by iisg_superadminWe’re continuing our celebration of Illinois Invasive Species Awareness Month with a few words from Cathy McGlynn, coordinator of the Northeast Illinois Invasive Plant Partnership, on how invasive species have changed our aquatic ecosystems.
I am your local co-coordinator of the Clean Boats Crew, an aquatic invasive species education and outreach campaign that is a collaboration of Illinois-Indiana Sea Grant and the Northeast Illinois Invasive Plant Partnership. My colleagues and I care very much about protecting aquatic ecosystems, and we know the value of prevention when it comes to invasion.
I haven’t always lived in the Chicago region. Once upon a time, I was a field biologist who lived in the Hudson River Valley and spent countless summer days canoeing to my research sites in the morning mist on the majestic Hudson River while being very careful to avoid tugboats and their wakes. I surveyed marsh birds and small mammals to see how invasive plants were impacting them. It turned out that native birds with special requirements, such as the marsh wren, were losing their nesting habitat to the invasive common reed. In between sites, I battled my way through beds of water chestnut, an aquatic invasive plant that has not yet been found in the Chicago area. I helped to survey and monitor native aquatic plants on the river with a team of volunteer kayakers because these plants provide important habitat for young fish, crabs, and insects and needed to be tracked. I was always careful not to walk around barefoot on the river’s beaches to avoid cutting my feet on zebra mussel shells or stepping on the barbed fruits of the water chestnut. During the time before I moved to this region, rock snot and Chinese mitten crab were starting to threaten the Hudson River and its wetlands.
After writing all of this, I realize that I don’t know a time, in my life anyway, that invasive plants and animals weren’t arriving and changing the Hudson River ecosystem.

Species spotlight: Grass carp
May 14th, 2015 by iisg_superadminINVASIVE SPECIES EDITION—Where we take a moment to explore the species that threaten the Great Lakes region.
They may not be what comes to mind when you think of invasive carp, but grass carp can have drastic and lasting impacts on aquatic ecosystems and water quality. Originally from eastern Asia, they have been introduced the world over as a biocontrol for aquatic weeds and can now be found in over 70 countries.
This wide range is made possible by their versatility—not unlike the hydrilla they are sometimes employed to eliminate. Grass carp can live in water temperatures from below freezing to over 100ºF, can survive in brackish waters, and are able to tolerate low-oxygen environments.

Website of the week: Be an AIS super sleuth
February 10th, 2015 by iisg_superadminA closer look at web tools and sites that boost research and empower Great Lakes communities to secure a healthy environment and economy.
Hundreds of invasive species are on the loose in U.S. waters wreaking havoc on habitats, recreation, and economies. Fortunately, a team of student detectives are on the case and ready to book these “bad guys” with help from Nab the Aquatic Invader!
This educational website turns students grades 4-10 into PIs hot on the trail of some of the worst invaders in their region. After brushing up on detailed profiles complete with interrogation recordings, students take part in ongoing investigations led by veteran gumshoes. Whether they join as junior detectives or super sleuths, students learn to ID the suspects, expose the damage they cause, and stop invaders before they strike again.
The site also includes a teacher Top Desk Administrator with example projects that give students a chance to share what they’ve learned with their communities. Along with detailed summary reports, these examples make it easy for teachers to plan and implement successful AIS stewardship projects in their own classroom.
But you don’t have to go online to crack a case. A suite of card games and posters inspired by the website are also available. Students and adults alike can even join the hunt for the most wanted AIS at the Smithsonian National Museum of Natural History in D.C. and at Coastal Ecosystem Learning Centers throughout the country.
Nab the Aquatic Invader! was created by IISG and Sea Grant programs in New York, Louisiana, Connecticut, and Oregon.
Local citizen nabs invasive plant on sight
January 29th, 2015 by iisg_superadminWater gardeners—keep your eyes open this season for invasive plants that may be lurking at your neighborhood garden store. In recent years, Illinois and Indiana DNR have both added nearly 30 new species to their lists of banned aquatic plants, but some may still be available for sale.
If you spot one of these invaders, be sure to tell the store manager. Some species can be hard to identify and larger stores may not even know these plants are on their shipment list. That’s exactly what was happening at a Petco in Carbondale, IL, where Karla Gage found Brazilian elodea—aka Egeria densa—while browsing with her family.
“I notified the department manager that this was listed as an injurious species in Illinois, and I sent a follow up email to the store manager,” said Karla, coordinator of the River to River Cooperative Weed Management Area, which brings together federal, state, local, and private partners to tackle invasive plants in southern Illinois. “I received a call from the corporate contact, who stated that Petco stores in Illinois would no longer receive or be able to order Brazilian elodea. Previously, Carbondale stock had been on “auto-replenish,” so the stores never actually ordered Brazilian elodea. Current stock is being disposed of responsibly.”
“Thanks to Admin Code 805 and the quick response of Petco,” she added, “the risk of an introduction of Brazilian elodea into natural systems has been reduced.”
The Illinois and Indiana rules also make it illegal to gift, barter, exchange, loan, or transport the any listed species. Recent additions to the list—27 plant species in Illinois and 28 in Indiana—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. IISG’s aquatic invasive species (AIS) team 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.
Visit our AIS page for more information about invasive plants and animals on the market and what water gardeners and aquarium hobbyists can do to prevent their spread.

Illinois gets a jump on invasive species
January 27th, 2015 by iisg_superadminBut all that may be changing in Illinois due to a new database cataloging the presence of non-native species across the state. Created at Loyola University Chicago by then-graduate student Abigail Jacobs and ecologist Reuben Keller, the database brings together animal and plant sightings collected by the U.S. Geological Survey, Field Museum, Illinois Natural History Survey, and many other organizations and researchers. Its more than 20,000 records makes it one of the most comprehensive AIS databases in country.

Climate change is making it harder to manage sand on Chicago’s beaches, with rising water levels, bigger storms, and stronger winds. IISG-funded research led by C. Robin Mattheus and a team of ISGS scientists tracked sand distribution along 18 beaches—offering the first regional, high-resolution assessment of the Chicago shoreline. #SeaGrantFunded
