What is a National Geographic BioBlitz?

A National Geographic 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 a snapshot of an area’s biodiversity. These events can happen in most any geography—urban, rural, or suburban—in areas as small as a backyard or as large as a country.

Smartphone technologies and apps such as iNaturalist make collecting photographs and biological information about living things easy as part of a BioBlitz. High quality data uploaded to iNaturalist become part of the Global Biodiversity Information Facility, an open source database used by scientists and policy makers around the world. 

Plan a National Geographic BioBlitz

Get inspired with these BioBlitz Guides and videos to create an event at a school, in a park, or anywhere. Use the planning sheet to organize your ideas. During the event, collect observation data using the iNaturalist app or on paper with these data sheets: BioBlitz Observation Guide, Species Identification Cards, or Data Chart.
