Registration opens June 3, 2024

Follow us on Facebook for event updates and all things invasive species:

Snapshot Day is a statewide, one-day event connecting volunteers, water lovers, and local groups in a search for aquatic invasive species (AIS). You can help protect Wisconsin’s rivers, lakes, and wetlands from these invasive plants and animals that may negatively impact habitat, wildlife, recreation and health. This event is coordinated in partnership with UW-Madison Division of Extension, Wisconsin Department of Natural Resources, local partners, and YOU!

Volunteers will look for invasive species at critical monitoring sites, and potential invasive species will be verified and cataloged with the Wisconsin Department of Natural Resources to guide species control and conservation management plans.  No experience is necessary and training is provided virtually prior to the event.

This is event is recommended for ages 8 and up; minors must be accompanied by an adult.
