City Nature Challenge 2023


April 5, 2023

This year, City of Melbourne is participating in this City Nature Challenge – a global citizen science BioBlitz event running from Friday 28 April to Monday 1 May. During this four day challenge, we need your help to survey our city’s biodiversity using iNaturalist. We’re competing against other cities around the world to see who can make the most observations, find the most species, and engage the most people. Let’s show the world Melbourne’s unique and rich biodiversity.

Get involved by recording your nature observations using iNaturalist, or joining one of our free BioBlitz events led by our expert researchers, park rangers and local community groups.
