An invasive aquatic plant that crowds out native plants and prevents sunlight from reaching those submerged is considered established in Michigan. It was listed on the state’s invasive species watch list in 2011.
A recent review of European frog-bit determined the plant no longer met watch list criteria due to its establishment in many areas statewide, the Michigan Department of Natural Resources announced Tuesday.
“European frog-bit still retains its prohibited status, making it unlawful to possess, introduce, import or sell in Michigan,” the DNR wrote in a Tuesday press release. “State and local management efforts for European frog-bit will continue despite the status change.”
