Aquatic Invasive Species (AIS) Monitoring
Aquatic invasive species distribution information is tracked by citizens and employees.
Disclaimer: Aquatic invasive species (AIS) records are assigned statuses of "verified", "observed", or "no longer observed" based on AIS Status Guidance. In general, "verified" populations are established and have been verified by a taxonomic expert. Populations with the "observed" status have not been verified by a taxonomic expert or do not have established populations. Populations with the "no longer observed" status include populations where a reproducing population did not establish. Our inventories are not necessarily exhaustive so it is important to report occurrences:

Citizen Lake Monitoring
The Citizen Lake Monitoring Network, the core of the Wisconsin Lakes Partnership, creates a bond between over 1000 citizen volunteers statewide and the Wisconsin DNR. Our goals are to collect high quality data, to educate and empower volunteers, and to share this data and knowledge. Learn More
AIS Baseline Monitoring
A multi-year statewide effort to collect baseline AIS distribution information on lakes with boat landings was started in 2011. WDNR staff, county and regional partners will search a new set of approximately 200 lakes each year for at least five years. This endeavor will allow a statistically valid evaluation of all of the lakes in Wisconsin with boat landings and enable DNR to:
- Establish baseline data on statewide AIS distribution.
- Track the rate of AIS spread among the most vulnerable Wisconsin lakes.
- Evaluate the effectiveness of outreach and education efforts to slow the spread of AIS via recreational boating.
