Invasive Species
How Wisconsin Is Doing

Wisconsin is working hard to slow the spread of aquatic invasive species in our lakes and rivers. Once these species become established in a waterbody it is basically impossible to eradicate them, so preventing their spread is the best strategy. DNR staff and citizens throughout Wisconsin help this effort by monitoring lakes and rivers for the most problematic aquatic invasive species. Volunteers and staff also work at boat landings to educate boaters on preventing the spread of invasives.
