Great Southern BioBlitz Day 3 and 4
Location
Hosted by
Green Heroes LTD About
The Great Southern BioBlitz is a spring snapshot of life across the entire southern hemisphere. Over four days, people in Australia, New Zealand, South America and southern Africa record every living thing they can find and upload it to iNaturalist — building a single, shared picture of southern biodiversity.
GSB 2026 runs Friday 27 to Monday 30 November, with a further 14 days afterwards to upload and identify everything you recorded.
Green Heroes takes that global effort underwater at Cook Island Aquatic Reserve. Fish, invertebrates, corals, algae, seabirds, turtles — if it lives here, we want it on the record. Reef sites are badly under-represented in bioblitz data, which makes what we capture here genuinely valuable.
