A BioBlitz is an event that focuses on finding and identifying as many species as possible in a specific area over a short period of time. At a BioBlitz, scientists, families, students, teachers, and other community members work together to get an overall count of the plants, animals, fungi, and other organisms that live in a place.
Why Participate in a BioBlitz?
1. Explore Nature With an Expert Guide
Scientists will lead you on a special informative tour, pointing out the special natural attractions near you!
2. Join a Species Inventory
If you sign up to officially participate, you’ll join a biological species counting expedition, and your team could be the first to find a new species.
3. Share Your Photos With Scientists
It's as easy as taking photos of the plants and animals you see and loading them into iNaturalist, which provides a place to record observations and get help with species identification from scientists. Learn More About iNaturalist.
