Great Lakes BioBlitz 2024

iNaturalist logo

Educators, students, families, youth groups, and the general public are invited to participate in the Great Lakes BioBlitz, a community science effort to record as many species within a designated location and time period as possible. This bioblitz focuses on the entire Great Lakes Basin US and Canada. It runs for four weeks. 

Who should participate? 

Everyone! Teachers, educators, students, youth groups, individuals, and families.

Why should I participate? 

A bioblitz provides a way to record biodiversity – the variety of wild living things found in a given area. For the Great Lakes BioBlitz, residents of the states and provinces in the Great Lakes region work together to collect as many observations as possible. Biodiversity data can contribute to research and conservation efforts.


  • Starts: Earth Day, Monday, April 22, to Saturday, May 18, 2024
  • Ends: Saturday, May 18, 2024
  • The Great Lakes BioBlitz will remain open for submissions from April 22 to May 18, but you can join in the fun any day! Take an afternoon to explore and document some plant 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.  


The bioblitz will take place in yards and other outdoor spaces all across Ontario and Quebec, Canada, and the Great Lakes states: Minnesota, Wisconsin, Michigan, Illinois, Indiana, Ohio, Pennsylvania, and New York.
