What’s blooming, flying, swimming, hopping, or maybe just growing around you? 

Every spring, the Center for Great Lakes Literacy and Great Lakes Sea Grant Network hosts the Great Lakes BioBlitz, a community science effort around the Great Lakes watershed to record as many species within a designated location and time period as possible. Educators, students, families, youth groups, and the public are invited to participate and make observations of wild, living things on the iNaturalist app!
