MiCorps Aquatic Invasive Species Detection Blitz

The MiCorps AIS Detection Blitz is a statewide community science event aimed at identifying and documenting aquatic invasive species such as zebra mussels, Eurasian watermilfoil, or anything else you suspect may be invasive in Michigan’s lakes, rivers, and wetlands. Organized by the Michigan Clean Water Corps (MiCorps), this Blitz welcomes volunteers of all backgrounds, whether you're a seasoned naturalist or a first-time observer. Every summer during a specific time period, simply snap photos of potential invasive species and upload them to the MiCorps project on the free iNaturalist app. By working together in this coordinated effort, we can track the spread of AIS, strengthen early detection strategies, and inform better management decisions.

The 2026 Blitz took place June 29 - July 12. You can see the results on iNaturalist. Nearly 300 AIS reports were received and verified across Michigan!

We want your feedback!

If you signed up to participate, please share your feedback through our quick, 5-minute survey.

Instructional Webinar!

We hosted a webinar on June 9 for interested participants and partners: "Getting Started with the MiCorps AIS Detection Blitz".

Why This Matters

• Invasive Species Threaten Local Waters

  They can outcompete native species, reduce biodiversity, and impact the overall health of lakes, rivers, and wetlands.

• Early Detection is Crucial

  The sooner new invasions are identified, the easier it is to prevent them from spreading and causing long-term damage.

• A Statewide Effort

  By documenting possible AIS during this event, we build a clearer understanding of where aquatic invasive species are emerging or expanding across Michigan.

Help Spread the Word or Host Your Own Local Event!

We welcome organizations across Michigan to promote the MiCorps AIS Detection Blitz or host local collection events under this statewide project. Your involvement helps ensure more eyes are on our waters, strengthening our ability to map aquatic invasive species. Each year we develop and share resources for partners, including guidance on how to host a local event, images, and information you can share on social media, in newsletters, and other communications.

Your participation expands the impact!

• Do I have to be an expert?

  Not at all. Anyone can share observations - the iNaturalist community, other Blitz participants, and our AIS experts will do the ID work.

• What if I find something non-invasive?

  That's still useful data, and it helps build a better understanding of our aquatic ecosystems, but only add photos of species that you suspect might be invasive. If you aren't sure, add it!

• Can I participate if I'm not near a lake?

  Yes! Streams, ponds, and wetlands count, too. Any freshwater habitat in Michigan is fair game.

• Do I need special equipment?

  A smartphone or digital camera is enough. Just be mindful of safety when you're in or near water.

• Do I need cell service at the site?

  No. You can take photos in the iNaturalist app (or with your camera) while offline and upload them later when you are connected to the internet - just be sure to add the location to your observation manually during the upload process.

Other Statewide Information Hubs

• The Michigan Invasive Species Program has species profiles, early detection guidance, and best management practices for invasive species.

• Clean - Remove plants, mud, and debris from boats, trailers, waders, and gear before leaving any waterbody.

• Drain - Empty bilges, live wells, bait buckets, and any other water-holding compartments on site before leaving.

• Dry - Let gear and watercraft dry for at least five days, or wipe down thoroughly with a towel, before visiting another lake or stream
