Wisconsin

Invasive plants, animals and pests are taking a toll on Wisconsin’s lakes, rivers and landscapes. The DNR is working with citizens and partners to slow the spread of invasive species. Through educational outreach, strategic planning and active management we are protecting our environment and economy from invasives.
