2025 City Nature Challenge
Calling all nature lovers, help Knox compete with cities from around the world to capture and upload photographs of local wild plants and animals in the 2025 City Nature Challenge from Friday 25th April to Monday 28th April. Let’s show the world how incredible the biodiversity of Melbourne is.
What is the City Nature Challenge?
The City Nature Challenge is an annual global event that celebrates local wildlife and flora through citizen science. The event is coordinated by the California Academy of Sciences and the Los Angeles County Natural History Museum and was first run in 2016.
During the 4-day challenge snap a photo or record the sound of any wild plant or animal and upload it to the iNaturalist app. Make sure to include the location details too. At the end of the Challenge, the city with the most observations wins.
This challenge provides a fun and collaborative opportunity to participate in friendly competition and learn about local biodiversity.
