Did you know that a network of over 100 local citizen scientists have been observing, photographing, identifying and mapping Manningham's local biodiversity using their smartphone?

Want to get involved? Join the City Nature Challenge and take part in one of the biggest Citizen Science projects in the world. 

About the City Nature Challenge

The City Nature Challenge runs from Friday 28 April to Monday 1 May 2023.

In this worldwide BioBlitz, cities compete to make the most observations of the most species by the most people.

Manningham is collaborating with over 25 local governments to form the Greater Melbourne project.

How to participate

It is free, easy, and fun to get involved.

  1. Take photographs

    During the  four day window of this challenge, take photos of plants or animals and upload it to iNaturalist.

  2. Observations added

    Your observations will be added to the Manningham iNaturalist projects (Manningham East or Manningham West) so that we can compete with participants from across Melbourne and all over the world. 

  3. Database updated

    All data gets added to Australia’s database of plants and animals, helping scientists with their research to improve outcomes for our environment.

To prepare for the challenge:

  1. Install the iNaturalist app on your mobile phone and create an iNaturalist account.

  2. Start adding your observations.


iNaturalist can be used by anyone. The photographs you enter are shared via the iNaturalist platform. Local ecologists are on hand to help you identify and confirm your observations.
