The Wisconsin Invasive Species Calendar helps you determine what species to look for throughout the year based on life stage and detectability. Click on the image below to go to the calendar (you will be brought to a Tableau site). And check out the Wisconsin Invasive Species Calendar Quick Guide to learn more about using this tool.
The first version of the calendar was released in March 2019. The calendar will continue to be updated and refined, so you can expect some small changes as you revisit the calendar.
