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. Between June 29 and July 12, 2026, 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. Whether you're on the water for the July 4th holiday or just enjoying a local spot, every observation counts!
We are hosting a webinar on June 9 for interested participants and partners. Register today for the webinar: "Getting Started with the MiCorps AIS Detection Blitz. The webinar will be recorded and shared here.
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.

Find This Project
Search for "2026 MiCorps AIS Detection Blitz" and join the project so the observations you make during the project period are included.
Go Out & Observe
Between June 29 and July 12, visit any Michigan waterbody and snap photos of plants or animals you suspect could be invasive.
Upload & Confirm Details
When uploading photos, make sure each observation has the correct date, time, location, and that you have joined the MiCorps AIS Detection Blitz project so your observations are included. You can add multiple photos to help with identification.
Check Back
Experts and fellow users on iNaturalist will help identify your finds. Watch for feedback on your observations!

Need Help?
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.
Promote the Blitz:
Use our ready-made social media graphics and outreach materials to inform your community about this important statewide effort.
Host a Local Event:
Want to organize a local collection event during the Blitz? Great! When your participants join the project on iNaturalist, your event will become part of the statewide MiCorps AIS Detection Blitz - no need to create a separate project.
Download what you need for your event or promo from the AIS Blitz Partner Kit (below) for promotional graphics and sample language to support your event and 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
More tips and printable checklists at Clean Boats, Clean Waters.
Heads up! The Great Lakes AIS Landing Blitz runs the same dates as our MiCorps AIS Detection Blitz - double the reason to clean, drain, and dry every trip! This multi-state event encourages boaters across the region to prevent the spread of aquatic invasive species, and provides materials, grants, and events to help spread the word.
