Invasive Species

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.

Report a Violation

The DNR's Violation Hotline provides Wisconsin citizens with the opportunity to confidentially report suspected wildlife, recreational and environmental violations using a toll free number.

These violations may include fishing or hunting out of season, night hunting, exceeding bag limits, illegal sale of fish and wildlife, deposit of harmful substances in lakes or rivers or illegal storage or disposal of hazardous waste. All these violations seriously affect our state's natural resources.

The hotline number is in operation 24 hours a day, 7 days a week. Trained staff relay reported information to our conservation wardens. Anyone who calls the hotline or provides information can remain anonymous.
