National Biodiversity Assessment

The NBA is the primary tool for monitoring and reporting on the state of biodiversity in South Africa, and is produced by the South African National Biodiversity Institute in partnership with numerous institutions and individuals.


NBA 2025 will be released in December 2025.


More about the NBA can be found on the SANBI website, where you can download the Contextual and Operational Framework document that provides a full overview of the context of South Africa’s NBA, its purpose, its scope and how it is undertaken.
