Great Lakes BioBlitz

media release: What is the Great Lakes BioBlitz?

A free event that focuses on finding and identifying as many wild, living things as possible in the Canadian provinces and U.S. states that border the Great Lakes during a specified period of time.

When is the Great Lakes BioBlitz?

The BioBlitz begins on Earth Day (Saturday, April 22) and it runs for four weeks, ending on Saturday, May 20.

How do I participate in the Great Lakes BioBlitz?

The beauty of this project is that you decide your level of participation. Take an afternoon to explore and document some plants or wildlife in an area, or pick a location to return to weekly, or set a goal to find something new every day–there are many ways to participate. You may participate as an individual, a family, a class, or other group.

Joining is as easy as saying “One-two-three-CHEESE!”

1. Visit iNaturalist and create a free account or login to an existing account.  

2. Sign up for the 2023 Great Lakes BioBlitz project!

3. Make observations and upload them! Take a picture or record some audio with iNaturalist and it will automatically be included in the 2023 Great Lakes BioBlitz if it matches the project's requirements.
