AQUATIC AND WETLAND INVASIVES SPECIES MONITORING

The Wisconsin Department of Natural Resources (DNR) Aquatic Invasive Species Monitoring program is a collaboration of citizens, partners and the DNR to find, report, map and survey invasive species. The program is guided by species identified in NR 40, Wis. Adm. Code.

This monitoring effort detects new invasive species so the DNR can be alerted and stakeholders can respond appropriately. The DNR collects this data to know what methods trained citizens and partners use when actively looking for invasive species. All records are screened by the DNR and every new invasive species occurrence is verified and appears on the DNR website (see the "Location" section below).

For surveillance monitoring, a report of "no invasive species" at a location is just as important as finding invasive species. Knowing how often our monitors are looking for species and what they are or are not finding is critical in understanding the spread of invasive species. These raw data are available in the Surface Water Integrated Management System (SWIMS) database.

Understanding Invasive SpeciesThis page includes links to learn more about aquatic, wetland and terrestrial invasive species. Within those pages you can find information on plants and animals regulated under NR 40 including NR40 Classification; common and scientific name; factsheets; photos; literature reviews; Species Assessment Group form; and NR 40 listing date. Identification information is found in the factsheet. Brochures can be found in the Resources tab.

Locations

The following documents provide guidance on how to determine known locations of aquatic and wetland invasive species. Please report any aquatic or wetland invasive species occurrence that is not identified in these resources.

TitleDescription
Lake, Stream and Wetland Aquatic Invasive Species Mapping ToolThis tool will give you the option to see "verified" aquatic and wetland occurrences, as well as occurrences listed as "no longer observed" in SWIMS. To see these occurrences, use tools in either the "Basic Tools" or "Find Locations" tab to locate the lake you’re interested in, and bring up the "Map Layers" tab on the bar along the left side of the screen. Once you’re there, expand one of the following categories to select the species you would like information for: invasive aquatic plants, invasive fish, invasive invertebrates, or invasive wetland and riparian plants. To get information on the populations in a location, use one of the tools in the "Identify Tools" tab and select the waterbody/area of interest. Then click the entries that appear on the left side of the screen to get further occurrence information.
Aquatic Invasive Species by Species ListsThis webpage contains a list of species. Click on the species you are interested in and then use the drop-down menu to search for the desired location. This list shows verified and no longer observed populations and links to limited details for each occurrence. Locate the waterbody you would like information for and click on the "Details" link to get more information on the occurrence of the desired species. A screen will pop up with limited information for that occurrence.
Aquatic Invasive Species by Waterbody ListsUse the drop-down menu to select the location of the waterbody you would like species information for. This list will show species that are listed as verified and observed, with an asterisk denoting observed records. Further detail on occurrences cannot be accessed through this tool.
Where Boaters Have BeenThe “Where Boaters Have Been” Map is generated from data collected by Clean Boats, Clean Waters watercraft inspectors while assessing whether boats have been cleaned and interviewing boaters on what waterbodies boaters visited before visiting a lake.
Center for Limnology Suitability Models [exit DNR] (NOTE: does not work in Internet Explorer)UW-Madison Center for Limnology has created suitability models for zebra mussels (Dreissena polymorpha), rainbow smelt (Osmerus mordax), round goby (Neogobius melanostomus), rusty crayfish (Orconectes rusticus), spiny water flea (Bythotrephes longimanus) and Eurasian water milfoil (Myriophyllum spicatum).

SWIMS Help

DNR aquatic and wetland invasive species staff manage reports in the Surface Water Integrated Management System (SWIMS) database.

The data in SWIMS is shown on DNR webpages and mapping tools when staff creates Resources of Interest (ROIs) that are directly related to AIS discoveries reported in the database as fieldwork events (even if that report comes in from a citizen who doesn't happen to be part of a volunteer program). Below are helpful tools for DNR staff.
