A global dataset of taxa to support calibration of invasion risk screening applications

This dataset contains a global compilation of taxa with a priori invasion-status categorisation derived from applications of the Invasiveness Screening Kit (ISK) family of decision-support tools. The deposit includes the main dataset (ISK_categorisation_dataset.csv), a metadata dictionary (ISK_categorisation_dataset_metadata.csv), and a README file describing the dataset structure, coding conventions, file contents, and citation instructions. The resource is intended to support calibration, comparison, and reproducible use of invasion risk-screening outputs for non-native species.
