Spring 2020 Citizen Science Workshops

In Spring 2020, WIFDN is teaming up with three regional groups to host ONLINE invasive species citizen science workshops for volunteers, land owners, and land managers. Attendees will learn how to identify priority invasive plants in their regions of Wisconsin, as well as how to monitor for and map those species using the Great Lakes Early Detection Network app. Our local partners will share how you can help their efforts by mapping priority species and monitoring in priority areas. The good news is that looking for and mapping invasive species is an easy outdoor activity to do while adhering to social distancing guidelines!
