Why the Great Lakes BioBlitz? In 2020, in response to requests for activities that get youth and families outdoors, the Center for Great Lakes Literacy launched the Great Lakes wide project, Great Lakes BioBlitz (formerly called the Great Lakes Educators’ BioBlitz). We encourage our communities to use iNaturalist to post photo observations of as many wild, living things in a specific area over a short period of time as possible. Why would we want to encourage our community to do this? Participating in a BioBlitz is a good way to engage in an outdoor activity. It can provide teachers and families with a tool to get outside and engage in making observations and learning about wild living things in the world around them. Teachers, youth, and their families can participate directly in an online community of observers. Participants can make observations for their state project and see how many observations are being made in other states. From a Great Lakes Literacy standpoint, links can be found in Great Lakes Literacy Principle #5. How do I get on to iNaturalist and join in the BioBlitz? Joining is as easy as saying "One-two-three-CHEESE!"
