Aquatic Invasive Species Snapshot Day 2026

AIS 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 meet at a local training site of their choosing, hosted by one of our local partners. After a short training on how to identify target aquatic invasive species and how to follow search protocols, 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. This is a free event and no experience or special equipment is required.
Registration opens June 1, 2026.
