You’re invited to help us capture biodiversity in Stonnington and Victoria in the global City Nature Challenge!

We are joining forces with seven local councils to compete with 250 cities from over 40 countries around the world.

This biodiversity project will take place from 30 April to 3 May 2021.

Over four days, we need your help to record and photograph as much local biodiversity as possible. From wild plants and animals to insects and fungi. Capture and upload your findings to iNaturalist, the global challenge app.

Your observations will be added to our challenge leader board. This is where you can track and compare all observations and species with other participating countries.

At the end of the challenge, we will share the results with the community. You'll see how you’ve contributed to recording biodiversity in our City and around the world!

Your records will also contribute to real species databases. This means you'll be helping us better understand urban biodiversity so that we can work to protect it.

Other participating east Melbourne Councils include Boroondara, Whitehorse, Knox, Manningham, Monash, Maroondah and Greater Dandenong.

What type of species should I look for?

Any living thing including a plant, animal or fungus can be recorded on iNaturalist.

You can observe all sorts of species - big and small, native and non-native, wild and cultivated.

Please don’t record humans, pets or indoor houseplants.

Remember to observe nature at a variety of locations - backyards, streets, in trees, waterways and under rocks, and in less likely locations such as footpaths and even indoors.

It’s also important to look for species at different times of day. Different species have different habits.
