BioBlitzes are citizen science, data collection events that help us understand the range of biodiversity in this garden city of ours. There are different ways that citizen science data can be collected. One way is to record nature observations through iNaturalist – a platform where anyone in the world can upload photos of plants, animals and fungi they observe.

Run every few years, our BioBlitzes bring experts and members of the community together to discover and document the species which call Melbourne home.

Our next BioBlitz is happening from Monday 1 March to Saturday 7 March 2026.

Insect BioBlitz 2026

From 1 to 7 March 2026, discover and document Melbourne's local critters.
