City Nature Challenge - Hobsons Bay

The annual City Nature Challenge is running from Friday 28 April to Monday 1 May 2023. Get out into your garden or visit your local park, creek or nature reserve to take some photos of wild animals, plants and fungi. Upload your photos (or sound recordings) as observations to the iNaturalist platform for identification by 7 May, using the phone app or webpage. 

This four-day biodiversity blitz is a global effort, with 445 cities from 47 countries involved in 2022, where 1.7 million observations were made and over 50,000 species were recorded. As a friendly competition, cities aim to record as many species possible, and make the most observations by the biggest number of observers, shown on the global tally board.  

Hobsons Bay is part of the Greater Melbourne collaboration project with over 25 other local government areas. Let’s showcase Australia’s amazing wildlife to the world! 

Your observations will also be automatically added to the Hobsons Bay project, which is an important, ongoing record of the species living in our neighbourhoods.

An online session about City Nature Challenge and using iNaturalist will be held on Wednesday 26 April, 7.30pm to 9pm.
