Asia Nature Challenge (ANC) is a continent-wide citizen science event designed to significantly enhance biodiversity data collection across Asia. This two-part event will bring together participants from across Asia to document the region’s diverse flora and fauna. Participants will be encouraged to get out and take observations of their surrounding environments between October 18-21, and then there will be a focus on teaming up with experts between October 22-27 to do identifications on the observations collected.
