Great Southern BioBlitz 24-27 November 2023


Block out your diaries and rally your friends, the 2023 Great Southern BioBlitz is fast approaching.

Castlemaine Field Naturalists Club is the project host for our local area and Club members and all others are encouraged to participate. This annual event is an intensive four-day effort by citizen scientists across the southern hemisphere to record all living species. Apart from being great fun, every one of us can contribute to the hugely important task of mapping species, their locations and numbers, and assist scientists in their work for biodiversity.

The GSB runs on the online platform iNaturalist, a global online network where citizen scientists, naturalists and biologists upload their photos or audio recordings and help each other identify the species. Now is the time to practice your iNaturalist skills or create a logon and load some sightings if you are new to the platform.

This year we hope to run some activities for people who are taking part in GSB2023.  Watch this space for future announcements.

For more information, visit Great Southern Bioblitz 2023: Castlemaine Region on the iNaturalist website and join the project to receive occasional updates. During and after the BioBlitz, this site is where your observations will appear and identification activity will happen.

You can also see who else is taking part by visiting the GSB Umbrella project at and look at the results to see what was found and how we did last year at
