Methodology:
National inventories of NIS were revised and updated with published data from biodiversity and hot-spot campaigns, academic surveys, and citizen science observed until December 2020 (reported until June 2022). The revised list was validated with the contribution of national experts.
Microalgae and parasite/pathogen species identified are excluded.
Cryptogenic, questionable and range-expanding species identified are also excluded from all analysis.
Native, partly native species identified are excluded at EU level but included in sub-regional assessments for subregions where they have not been identified as native.-

Additional information
- The pie chart shows the proportions of NIS introduced between 1970 and 2020 through various dispersal pathways.
- The column chart shows the contribution of each pathway per 6-year interval since 1970. The 'Unknown' category is not included to highlight the modes of introduction that have been detected.
