Aquatic Invasive Species Week is this week, June 26 to July 4, so this is a good time to learn about the impact invasives have on Great Lakes fish habitat.

In an article in the 2020 State of the Great Lakes Report, staff from the Michigan Department of Natural Resources discuss the importance of reefs in providing food and spawning areas for fish. Many of these reefs are under duress from invasive species, particularly zebra and quagga mussels.

This story map based on the DNR's article in the annual State of the Great Lakes Report looks at the stressors on Great Lakes reefs, including aquatic invasive species such as mussels and the round goby.

The full State of the Great Lakes report is posted to the Office of the Great Lakes website.

The Michigan Department of Environment, Great Lakes, and Energy (EGLE), DNR and the Michigan Department of Agriculture and Rural Development are partners with local groups and stakeholders in identifying and controlling aquatic invasive species. For more information, consult the Michigan Invasive Species website.
