Aquatic Invasive species - Non-regulated plants

Whether they come in ballast water, on the hulls of recreation boats or from the water of an angler’s bait bucket, many non-native species such as zebra mussels and Eurasian water milfoil have found their way into Wisconsin’s waterways. Their presence can cause severe damage to local ecosystems, industry and tourism. However, the Wisconsin DNR is part of a strong partnership of public and private stakeholders in Wisconsin committed to an effective strategy of prevention, containment and control. The more you know about these invaders, the more you can do to help stop the spread to Wisconsin's precious waters.
