The Great Southern Bioblitz is an annual international INaturalist app event where anyone can upload photos of whatever living thing they find in the world around us. The photos are then identified and added to a global database used by scientists, researchers, students, governments, not for profits and more.
The GSB is specifically a competition for regions in the Southern Hemisphere where it is Spring.
