WIFDN has generated an interactive table that contains invasive and potentially invasive plant species from 1900 to 2024 in Wisconsin. While it largely follows Wisconsin NR40, WIFDN staff has worked to add other species at a high risk for destructive spread in the state.

Find your county of interest below! Zoom in to see county names or click the [ ] to make it full screen. By clicking on a county shape, you can then click a link in the description that open a list of species occurrences for that county. There are options for downloading the data at the top of the table.

Or, click here to download the master table of all counties sorted by individual tabs in a spreadsheet, or here to see it in Google Sheets.
