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: June 2017

June is Invasive Species Awareness Month in Wisconsin. This month’s GLEDN Monthly Challenge celebrates the sixth month of the year and raises awareness of the variety of species that are regulated as invasive species in Wisconsin. The June challenge is to submit reports of at least 6 different species using the GLEDN app or EDDMapS. That’s it! Just 6 reports observed in June to complete the challenge! To include your reports from June in the challenge, make sure to submit them by Monday, July 3rd.

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.
