Laura Bourgeau-Chavez and Colin Brooks—research scientists at the Michigan Tech Research Institute (MTRI)—and Casey Huckins, a professor of biology at Michigan Tech, are leading projects to develop better management strategies to protect the state's shorelines along the Great Lakes. Researchers scrape the dock's wooden pilings for zebra mussels, counting them to track the density of the invasive species in the lake. They are known to modify food webs which alters energy pathways, changes lake productivity, and disrupts fisheries, costing millions of dollars annually in control and mitigation.

Lake Michigan Wildlife and Overfishing, Salmon Introduction, Invasive Species. We’re working to keep new ones out. “Lake Carriers’ has been and is engaging with state and federal regulators to develop plans to refine best management practices to prevent any inter-lake spread, seek out promising treatment technology, and test ballast water management systems on board lakers,” he said in an email. © 2020 Advance Local Media LLC. Once invasive species are established in the Great Lakes, it is nearly impossible to remove them. Scientists recently reported pronounced reductions in both cladophora algae and quagga mussel density in Lake Michigan’s offshore waters near Sleeping Bear Dunes National Lakeshore after an underwater project by the Invasive Mussel Collaborative. Another unfortunately very common invasive species in Michigan (and one of the most destructive), purple loosestrife is still often purchased and planted by gardeners and landscapers due to its beautiful, tall purple blooms. Lakers comprise about 95% of the ships working in the Great Lakes, Kirkwood said. These programs range from local to federal in scope. Invasive species are perhaps the greatest stressor currently facing the Great Lakes aquatic ecosystem. As a result, the EPA was not going to regulate them. Invasive species: a long-term assessment of the the zebra mussel invasion in the inland lakes of southern Michigan (with MSU); Land use and climate change: a study of how climate-affected environmental factors constrain the structure and function of the Great Lakes “food web,” with a look toward predicting how climate change will impact carbon emissions (with GVSU and NOAA); and Another invasive species in Lake Michigan that's creating unusual impacts and causing irreversible damage is mussels. Today, the United States and Canada require that most ships entering the Great Lakes exchange their ballast water while still at sea to reduce the transport and introduction of new species. Native to Eurasia, some North American nurseries argue that it has value here in its ability to attract pollinators – however, its detriments far outweigh this.

Because of the threat that these invasive species pose to our inland lakes, it is important that we know how to identify them, work to prevent their introduction into lakes where they are not currently found, and understand the available management options if they are found in a lake . The Great Lakes-St. Lawrence Legislative Caucus’s series of quarterly meetings for 2020 closed out with a presentation on aquatic invasive species and ballast water management from Sarah LeSage, who coordinates the Aquatic Invasive Species program in the Water Resources Division of Michigan’s Department of Environment, Great Lakes, and Energy.
