Take part in our bioblitz this September and help us build a better snapshot of the birds, little critters, plants, weeds and wildlife that can be found in the Yarra Catchment. Plus, everyone who takes part in our bioblitz will go in the running to win prizes.

How can you join? All you need to do is grab your phone, download the iNaturalist app and set aside a couple of minutes to appreciate and observe the nature that you can find in your garden, by your balcony or during your one hour of exercise.

Why a bioblitz? The goal is to achieve as many sightings of our wonderful and varied environment from our co-inhabiting wildlife, plants, flowers and bugs! Data from every observation submitted to our projects directly feeds into scientific databases like our Yarra Catchment Atlas and the Living Atlas of Australia. By submitting a photo to one of our projects, you are helping to increase our knowledge of the biodiversity found in the Yarra Catchment.

Not sure where to start? Use our Weeding Toolkit, Wildlife Toolkit and Little Critters Toolkit to help kickstart your observations.

How to get started 

  1. Download the iNaturalist app using your smartphone or iPad and create an account or login.
  2. Using the app, search YRKA biodiversity month and join the project that is within your 5km radius / local area.
  3. Take a look around your backyard, balcony, front yard or during your 1 hour of exercise and look for the plants and wildlife living all around you.
  4.  Using the app, take a photo of the plant or wildlife you’ve discovered, or upload it from your camera. Submit it to the YRKA Project through the app.

One of our bigger bioblitz areas, the Stonnington bioblitz stretches from South Yarra through to Chadstone.
