“Plant species 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. At the request of Indiana Department of Natural Resources, Illinois-Indiana Sea Grant 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. Their efforts led to a rule approved last year that bans the sale of 28 invasive aquatic plants in Indiana.‘It is important to have consistent regulations across the Great Lakes Basin. We want our policies to be consistent with our neighbors since invasive species don’t respect political boundaries,’ said Kevin Irons, aquaculture and aquatic nuisance species program manager for Illinois DNR. ‘Prevention is the first and cheapest way to protect Illinois from aquatic invasive plants, and risk assessment tools like the one built in Indiana allow us to identify and control high risk species without unduly regulating the industry.'”

IISG in the news: Injurious species list results in a ban on invasive plants
November 20th, 2013 by Irene MilesGreat Lakes education conference features several sessions, including IISG education team
November 15th, 2013 by Irene MilesThe 3rd Annual Great Lakes Place-based Education Conference, November 7-9 in Grand Rapids, Michigan, brought together over 200 teachers, community representatives, non-profit organization educators, and more. The conference gives teachers an opportunity to incorporate the latest place-based research and education concepts about the Great Lakes into their lessons, encouraging student stewardship, continuing science education, and community development.
Representatives of the CGLL program from seven Great Lakes Sea Grant programs were on hand to talk with attendees about the wide array of resources available, many specifically tailored to the environmental needs and issues of their region. Classroom resources were also available, including Fresh and Salt and Greatest of the Great Lakes curricula, as well as the Dose of Reality newspaper activity guide that covers the disposal of unwanted medicines and personal care products.
In the news: Biologists take samples in Sturgeon Bay searching for Asian carp evidence
November 14th, 2013 by Irene Miles“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.”
Sea Grant staff from across the U.S. completed Sea Grant Academy last month
November 12th, 2013 by Irene MilesStaff members from 20 different Sea Grant programs across the U.S. attended two Sea Grant Academy sessions this year (one week in April, and one in October). The academy was developed to give Sea Grant employees valuable training and professional development information in a variety of fields, benefiting their work and the work of all Sea Grant programs at large.
Five staff members from Illinois-Indiana Sea Grant were able to attend, and participated in sessions ranging from the history of Sea Grant to project design and evaluation, social science training, time management, communicating the importance of ocean science to various audiences, and much more.
IISG’s Danielle Hilbrich, Greg Hitzroth, Kristin TePas, Kara Salazar, and Sarah Zack were among the more than 40 Sea Grant professionals who completed both weeks of training and graduated from Sea Grant Academy with new information and skills to bring to their work protecting the Great Lakes.

In the news: Great Lakes mayors target plastic pollution from personal care products
November 11th, 2013 by Irene MilesRecent research on Great Lakes contaminants has shown that microplastics – small beads of plastic used in many exfoliants, toothpastes, and other products – are contributing to pollution levels. As a result, mayors near the Great Lakes are calling on manufacturers to remove the plastics from their products.
From TheObserver.ca:
“The Great Lakes and St. Lawrence Cities Initiative, representing more than 100 Canadian and U.S. cities, is urging industry and governments to have microplastics removed from personal care products.
Its call came as a study on microplastic pollution was published based on sampling last summer on Lake Huron, Erie and Superior led by Sherri Mason, a professor at the State University of New York at Fredonia.
‘It takes that kind of initiative to get things to change,’ she said of the mayor’s support for the issue.
‘It’s not so much about cleaning it up, as it is about stopping it at its source.’
Mason returned to the lakes for seven weeks this summer to collect more samples, including one from the St. Clair River at Sarnia that will be analyzed as the study continues.
Samples taken in 2012 included green, blue and purple coloured spheres, similar to polypropylene and polyethylene microbeads in consumer products, such as facial cleaners.”

In the news: October rains raise water levels in Lakes Michigan, Huron
November 7th, 2013 by Irene MilesFollowing last year’s record low water levels in the Great Lakes, and in Lake Michigan and Lake Huron specifically, this year’s rains have helped push those levels back towards the historical average.
From MLive.com:
“Heavy October rain could help Lake Michigan and Lake Huron continue to rise toward the long term average water level. Lake Michigan – Huron is still 15 inches below the long term average, but is 11 inches higher than this time last year. Slowly the lake level is increasing. The lake levels will likely fall over the next four months. This is a normal cycle. If the lakes don’t fall as much as normal this winter, the lakes are set up to be higher next summer than this summer…All of this rain can help Lake Michigan – Huron not fall as much as usual in November.”
Sea Grant staffers take new interactive watershed planning tool for a spin
November 6th, 2013 by Irene Miles
The Tipping Points and Indicators tool uses watershed data and cutting-edge research to show planners where aquatic ecosystems in their region are stressed by various factors to the degree that they are in danger of crossing a “tipping point,” triggering rapid and sometimes irreversible shifts in their functioning. With help from a Sea Grant facilitator, planners can use the tool’s interactive maps and simulators to specify important regional priorities, pinpoint specific land use practices that threaten ecosystem health, and test how further development, restoration, or conservation projects would help or hurt. Together with suggested policies, ordinances, and outreach efforts, these features help planners develop watershed management plans that prevent ecosystems from being degraded beyond repair.
The tipping points tool is part of a four-year project funded by NOAA and EPA and coordinated by Illinois-Indiana Sea Grant. Research and outreach partners include Purdue University, University of Michigan, Michigan State University, University of Minnesota Duluth, University of Windsor, the Great Lakes Environmental Research Laboratory, the Cooperative Institute for Limnology and Ecosystem Research, the Great Lakes Restoration Initiative, NOAA, and the Sea Grant Great Lakes Network.

In 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.”
In the news: Great Lakes microplastic pollution research recently published
November 4th, 2013 by Irene Miles“Take a dip in lakes Erie, Huron, or Superior and you will be swimming in more than just water. According to a recently published study, these lakes contain an unexpectedly large amount of floating plastic debris. Even more surprising, much of what the researchers found were microplastic fragments and pellets like the kind used in toothpastes and facial and body scrubs. At less than one millimeter, these tiny pieces of plastic are too small to be filtered out at wastewater treatment facilities before the water is released into the lakes.
Researchers from 5 Gyres Institute and State University of New York (SUNY) Fredonia made the discovery in 2012 after collecting a total of 21 samples from the lakes. They found plastics in all but one sample. Of the three lakes, Lake Erie had the highest concentrations of plastics, roughly 90 percent of the total amount measured. The authors speculate that the high concentrations may be the result of currents carrying the plastics from the cities of Detroit, Cleveland, and Erie. Back in the lab, further inspection revealed that along with the microplastics, eight of the samples contained coal ash and coal fly ash (produced by coal-burning power plants).”
