Welcome to the Wisconsin First Detector Network!

The Wisconsin First Detector Network (WIFDN) is a community science program that empowers people to take action on 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 community scientists.


Record Your 2022 Volunteer Efforts!

Every year, people connected with WIFDN spend an incredible amount of time and energy working on invasive species monitoring, management, and outreach across the state. Over the past 5 years, you’ve reported over 15,000 hours, which equates to over $400,000 of efforts!

So now it’s time to share what you did in 2022! Please take 2 minutes to fill out our short survey that will ask you approximately how many hours you spent on invasive species efforts and how far you traveled. Whether you’ve done work on your own property or for a local park, whether you volunteer with another group or just on your own, we’d love to hear from you!

Thanks for taking the survey!

Learn more about WIFDN

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, spotted lanternfly, 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. Consider becoming a First Detector and help improve our network and minimize the impact and spread of invasive species in Wisconsin!
