24 - 27 November 2023

Tamar NRM is participating in the Great Southern BioBlitz in 2023 - the largest BioBlitz in the Southern Hemisphere! 

What is a BioBlitz?

A Bioblitz is a snapshot study of a specific location, where scientists and the community work together to survey and record as many species of flora, fauna, fungi and aquatic life within a nominated timeframe. 

Between the 24th to the 27th of November 2023 citizens young and old in the Tamar region can help record organisms during spring and showcase our beautiful biodiversity to the world.

Why participate?

The goal of the Great Southern BioBlitz is to document the flora, fauna, fish and fungi of the Southern Hemisphere while providing a platform for groups, associations, local governments and individuals to encourage engagement in citizen science across the southern hemisphere. 

Through the online platform iNaturalist we hope to increase environmental awareness and encourage citizens to contribute to the understanding of their local biodiversity.

Anyone can get involved in the GSB by using the iNaturalist platform/app.

What is iNaturalist?

iNaturalist is an online social network of naturalists, citizen scientists, and biologists built on the concept of mapping and sharing observations of biodiversity across the globe. Projects for each area will also be created using this platform.  

How can I get involved?

You can get involved by creating an account, joining our project GSB 2023-Tamar Valley and uploading observations of anything living (except domestic animals or humans) in the Tamar Valley,  during the event time frame (24th to the 27th of November).


This data will highlight the biodiversity of the Tamar Region.

Schools Day

24 Nov 2023

This is an opportunity for schools and students to become citizen scientists and be a part of the biggest bioblitz event across the southern hemisphere. 

Tamar NRM would like to support teachers of students in grade 5 and up in the Tamar Valley to get involved in the Great Southern BioBlitz. 

We can provide some training before the event (how to create an iNaturalist account, how to use the platform/app, join the right project etc.) and provide a lesson plan/ step by step guide on how to participate in the Great Southern BioBlitz with your class.

Training will be available up until 23 November 2023.

If your school is interested in getting involved please follow this link to express your interest, or email
