'Blitz with the Basin!

What's blooming, flying, hopping, or maybe just growing around you? This spring,  join us on the iNaturalist App to post your observations of wild living things.

The Sea Grant Great Lakes BioBlitz begins April 22nd and ends May 20th. 

All folks in U.S. States & Canadian provinces within (or adjacent to) the Great Lakes Basin are welcome to join! 

What is a BioBlitz?

A BioBlitz is an event to observe, identify, and record as many different, non-domesticated species as possible in a given area over a set period of time.  

How Does a BioBlitz Work?

The  BioBlitz will remain open for submissions during the above dates, and you can join in the fun any day! Take an afternoon to explore and document some wildlife in your area, pick a location to return to weekly, or set a goal to find something new every day.

If you take multiple images of the same individual organism, at the same time, in the same place, please post the images as a group (a single observation within iNaturalist).  

If you take multiple images of the same organism at different times or places, please post the images as different observations within iNaturalist.

In other words, an observation should include date, time, location, and organism identity (to the best of your ability).
