Great Southern Bioblitz - Amazing First Year!

Updated: May 17, 2021


The inaugural Great Southern Bioblitz has been and gone for the year, but it's echoes will no doubt resound for another orbit of the Earth, when we get to do it all over again!

What a massive first year! Three thousand observers participated in the Great Southern Bioblitz, collating over 90,000 observations from around the globe of more than 12,000 species! The umbrella project now represents an amazing and openly accessible display of citizen scientist biodiversity observations. This searchable database is a treasure trove for naturalists, educators, researchers and anyone interested in nature, just choose a project from any place in the world and explore the observations citizen scientists made of their local flora and fauna.

This is an incredible snapshot of the biodiversity of the southern hemisphere


To help us find and publish the most amazing observations you have taken, please 'fave' your own or other user's observations so they can be easily found on the project stats page.

Participation was greater than anything we could have anticipated. The incredible response from South America taking us all by surprise. Hundreds of new users to iNaturalist documenting their observations to the website. Lima in Peru had 229 participants with 6,485 observations, the Huila region in Columbia with 114 participants taking 3,506 observations, Quito & Pichincha in Ecuador had 144 participants with over 2,000 observations, and Brazil had nearly 2,000 observations including 168 species of birds.

Just check out the fun these guys from Colombia had on the weekend:


Not as surprising but nevertheless very impressive, was the ability of Cape Town to mobilise naturalists at short notice to get out and observe the natural world to share what they find. There is a staggering 16,066 observations of 2,370 species currently attributed to that region over the GSB weekend. Another fantastic contribution to the record of South Africa's biodiversity, further cementing their place as the global leaders of citizen science biodiversity surveys. Their neighbours at Garden Route also putting in a fantastic effort to take over 4,000 observations of around 1,500 species.
