The Great Southern BioBlitz 2025 generated an extensive and taxonomically rich dataset, capturing observations across multiple biological kingdoms and a wide range of taxonomic scales, from kingdoms and classes to orders. This summary presents an overview of how observations, unique taxa, and observer participation were distributed among major taxonomic groups, providing insight into both underlying biodiversity patterns and the influence of citizen-science dynamics.
