The 2025 Great Southern Bioblitz is just around the corner, running from Friday 24th October to Monday 27th October, and Maroondah is again offering a series of nature discovery activities to encourage you to participate!
So, get your smartphone out, download the iNaturalist app, and explore your backyard, your street or any of your local nature reserves and parklands within Maroondah. Join in the 2025 Great Southern Bioblitz by using iNaturalist to make observations of the wild plants, animals and fungi you can find! Then be amazed at how the image recognition in iNaturalist, and its vast online community of naturalists, can help identify what you have seen!
The Great Southern Bioblitz is an annual citizen science event for the southern hemisphere and is a spin-off from the City Nature Challenge, where nature enthusiasts worldwide will be observing and recording wild flora and fauna living in their local area and uploading it to the iNaturalist app (see attached).
Over the four-day Bioblitz, Maroondah City Council is running six free Nature Discovery Activities, to help you discover and learn about diversity of flora and fauna that feature in our local natural environment. Our experts will guide participants in observing local examples of fungi, fish, water bugs, reptiles, spiders and moths. Numbers are limited however, so get in while you can by registering via the links below.
Maroondah is again teaming up with other metropolitan Melbourne councils to represent “Greater Melbourne” on the global stage. By joining in and making observations of plants, animals and fungi over the four days you can help boost Maroondah’s and Greater Melbourne’s statistics in the Bioblitz and contribute to broader scientific data that can help improve biodiversity conservation.
You can also track how Maroondah is going against other councils from across metropolitan Melbourne here.
You are invited to register for any or all of the free Nature Discovery Activities being held within Maroondah during the four days, where you can learn about different species from expert guides. Activities are expected to fill up quickly so please don’t wait to book your spot/s.
In the event that an activity is fully booked, you can ask to be added to the waitlist for any spots that may become available.

Making an observation in iNaturalist is easy! Making an observation valuable to science requires a little more care – try to make sure what you are recording is “wild”, ie not captive, domesticated, planted or cultivated (such as a pet or farm animal, or something that has been planted in a garden or farm), and take note of the advice provided in the attached guide to ensure you record the characteristics that are needed for others to independently identify what you have seen.
Please don’t stop there! – you can make valuable observations in iNaturalist for Maroondah at any time, Great Southern Bioblitz or not! All observations ever made in iNaturalist within Maroondah can be explored here “Nature in Maroondah”.
Cheers and have fun!
