Invasive European frog-bit found in Mid-Michigan
Boaters, waterfowl hunters and anglers can help prevent further spread
The Department of Environment, Great Lakes, and Energy recently confirmed the presence of European frog-bit, an aquatic invasive plant, in four lakes within the Waterloo Recreation Area in Jackson and Washtenaw counties and one impoundment in the Dansville State Game Area in Ingham County.
Aquatic invasive species have the potential to harm Michigan’s environment, economy and human health. European frog-bit, which resembles a miniature water lily with leaves about the size of a quarter, can form dense mats on the surface of slow-moving waters like bayous, backwaters and wetlands. These mats can impede boat traffic and alter food and habitat for ducks and fish.

What you can do
To prevent further spread of European frog-bit, boaters, waterfowl hunters and anglers should “Clean, Drain and Dry” boats, trailers and gear before moving them to a new location.
Invasive Species Alert 2017: European frogbit has been detected in Great Lakes waterways along southeastern Michigan, in Lake Huron and in western Michigan lakes. This invasive species is not listed on the Midwest Aquatic Plant Reference Chart that was distributed to the membership in 2015.
