We invite guests to utilize their mobile phones and the app iNaturalist to join the competition. Join a BioBlitz each day to explore as a group and compete for the most posts. Receive trading points in Nature Exchange when you upload 5 nature finds into the event app!

Participating in the City Nature Challenge not only gives you the opportunity to explore your urban area, but is also a great tool for budding scientists and naturalists to understand and help the wildlife that coexists with us every day. Will you take the challenge?
