Join the southern hemisphere’s largest citizen science event with Conservation Volunteers Australia, and discover who your wild neighbours are through The Great Southern Bioblitz.

Conservation Volunteers Australia (CVA) takes science, and getting people involved in citizen science seriously. CVA creates citizen science volunteer opportunities for people to connect with and understand our natural world. We’re dedicated to being a catalyst for change through citizen science that is accessible, and part of long-term initiatives supporting Australian native habitat, threatened species, and investing in nature.

As part of this commitment we are organising events as part of The Great Southern BioBlitz 2021, which is taking place across the southern hemisphere on 22nd – 25th October 2021. We’ll be holding events in South Australia, Tasmania and Western Australia where you can tune in to nature and record what’s happening in your local area, but contribute to a much bigger movement for nature around the country, and indeed around the whole of the southern hemisphere!

What is a BioBlitz?

A BioBlitz is an event that focuses on finding and identifying as many species as possible in a specific area over a short period of time. At a BioBlitz, nature guides, families, students, photographers, and other community members work together to get a snapshot of an area’s biodiversity. These events can happen pretty much anywhere—urban, rural, or suburban—in areas as small as a backyard or as large as a state.

Smartphone tech and apps such as iNaturalist make collecting photographs and biological information about living things easy, as part of a BioBlitz. Observations and other data uploaded to iNaturalist will become part of the Atlas of Living Australia, which is used by researchers and policy makers around Australia and the world, to make better decisions about how to care for nature.

Get Involved

By taking part in the GSB2021 with CVA you will be part of increasing nature awareness and contribute to the understanding of the home range of various native flora, fauna and fungi.

To take part we’ve got two options:

Option 1: BioBlitz Together

Join CVA’s expert nature guides at a location near you to not only get hints and tips about how to use iNaturalist, but also let them bring the landscape to life with their knowledge about local plants and wildlife!

It’s easy as…

  1. Register for one of our events here
  2. Download the iNaturalist application to your device, create an account, and get familiar with the app in your backyard or local area
  3. Join us at the event to record observations of nature.


Option 2: BioBlitz in your Backyard

For many of us being able to connect with nature is currently limited to our backyard, local park or nature reserve. This year there is a backyard focus for the Great Southern BioBlitz, making sure we can all be part of Tuning In to nature wherever you are, and becoming citizen scientists. All you need to do to contribute is sign up here and we’ll send you a quick start guide to get you up and running!



About iNaturalist

iNaturalist is a global nature observation platform, with artificial intelligence built in to help identify the biodiversity around you. The App connects you with over 1,200,000 scientists and naturalists who will help identify and verify what you record.

Are you having issues getting the iNaturalist App on your device? If you join one of our CVA events in person, our team leaders will help you get set up, record observations, and make sure you’re contributing to the database of Australian biodiversity to help care for and protect our unique species.

Don’t worry if you can’t identify the plant or animal you’ve recorded, just make sure you get some good clear photos or sounds and use iNaturalist’s built in suggestions (hint: use the highest level – kingdom – rather than none, if you don’t know – it helps other scientists find and identify your images for you).

If you’ve made a recording in the 22-25 October period, there are a few days allowed by the BioBlitz organisers to allow the broader community to identify the observations submitted during the survey dates.

Need some tips on how to get started and get active over October 22-25 to be the citizen scientist on the spot in your backyard and local natural areas? Here are a few handy links to get you started from iNaturalist:
