Welcome to the Wisconsin First Detector Network!

The Wisconsin First Detector Network (WIFDN) is a citizen science network that empowers people to take action against invasive species through invasive species monitoring, management, and outreach. WIFDN provides training and resources through a combination of webinars, instructional videos, and hands-on workshops, in addition to providing volunteer opportunities to citizen scientists.


Announcing the GLEDN Monthly Challenge!

Announcing a new challenge sponsored by WIFDN! From May – October, WIFDN will post a monthly challenge for GLEDN users to promote use of the app and to focus on priority species during different times of the season. Anyone who submits reports in Wisconsin with the GLEDN app or EDDMapS is eligible to participate. Check out this guide to learn more! And here’s the first challenge:

GLEDN Monthly Challenge: May 2017
Spring is here, summer is on the way, and there are invasive species growing all over the state! In May, we encourage people to (re)acquaint themselves the the GLEDN app and to get outside and report any invasive species they see. The inaugural monthly challenge is to submit at least 15 reports of invasive species observed in Wisconsin during the month of May. All reports observed in Wisconsin in May and uploaded/submitted by Friday, June 2nd will be eligible. Remember, it takes less than a minute to create a report in the GLEDN app. Try it out while you’re walking your dog, biking, or hiking! Or set aside 30 minutes to report 15 infestations in your local natural area. We hope you accept the challenge!

Join us as we look back on WIFDN’s accomplishments in 2016 and look forward to 2017. We’ll learn about the invasive species we should be on the lookout for in 2017.

April 7, 2017: Drivers vs. Passengers

Click here to view a recording of the webinar!

Do invasive species drive changes in ecosystems, or are they merely passengers in change driven by other ecosystem changes? Learn about these competing ideas and examples of how different invasive species act in new ecosystems.

April 21, 2017: Take Action!

Click here to view a recording of the webinar!

Learn how you can take action against invasive species through surveying for and reporting invasive species. In addition, learn about efforts to control invasive species in Wisconsin

May 5, 2017: Citizen Science and Volunteer Opportunities
Citizen scientists (that’s you!) gather extremely valuable information that can be used by researchers and natural resource managers in Wisconsin and beyond. Learn about volunteer opportunities that will let you flex your citizen science muscles.

Invasive species are considered to be the number two threat to biodiversity, second only to habitat loss. The effects of invasive species are increasingly evident on Wisconsin’s landscape. Despite efforts by federal and state agencies, non-native insects, plants and diseases continue to establish and spread throughout our state, impacting our economy and environment. While some of these pests are here to stay, many others have not yet been found in Wisconsin, and still more are found at low enough levels that eradication may be possible. Efforts to prevent new introductions and to identify new infestations before they become well established are the best way to ensure the survival of many of Wisconsin’s iconic plants, animals, and ecosystems.

By joining Wisconsin First Detector Network, you will have access to online training resources brought to you by invasive species experts from across the state. Training topics include terrestrial and aquatic invasive species biology, identification, and reporting. We emphasize species of concern to Wisconsin (e.g. emerald ash borer, late blight, giant hogweed), but we also discuss general resources for other species. We invite participants who are already doing invasive species volunteer work in Wisconsin, as well as people who are looking for new volunteer opportunities.
