Restoring landscapes across the Mount Alexander Region

The Great Southern Bioblitz: 22-25 October 2021

Posted on 19 August, 2021 by Ivan

For several years the iNaturalist citizen science platform has run the City Nature Challenge – a gentle competition between cities and regions around the world to see which location can collect and identify the most sightings of life-forms in their area over a week-long period each March.

In 2020 the Great Southern Bioblitz was born. This is a similar event to City Nature Challenge but held in October (southern hemisphere spring) when more plants are flowering, animals are more active and fungi are still plentiful. This year, the Castlemaine Field Naturalists Club is hosting the Great Southern Bioblitz for our region of central Victoria, i.e., the Mount Alexander Shire and the eastern half of Hepburn Shire.

All are welcome and encouraged to contribute. You simply photograph as many plants and animals as you can within the region during the Bioblitz period, 22-25 October 2021, and load your sightings into iNaturalist via your phone or computer. Even if you are unable to record your own sightings you can still contribute by identifying the observations that others have uploaded.

The Great Southern Bioblitz is not only fun, but an important way of recording the life-forms that are present in our area. Once you add a sighting to iNaturalist, others can help with or verify the identification. Data are then fed into repositories such as Atlas of Living Australia and state biodiversity databases such as Victorian Biodiversity Atlas.
