The Swedish Red List 2025

checklist

The Swedish Red List is compiled by the Swedish Species Information Centre (SLU Artdatabanken) at the Swedish University of Agricultural Sciences as part of the environmental monitoring and assessment programme Biodiversity. It includes assessments of the extinction risk of species in Sweden. The Swedish Red List 2025 was published on 24 March 2026 and is the sixth Swedish Red List to use the International Union for Conservation of Nature (IUCN) Red List categories and criteria.

This dataset includes all taxa that have been categorized as red-listed: Regionally Extinct (RE), Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT) and Data Deficient (DD). All red-listed taxa are included regardless of taxon rank, i.e. it includes for example subspecies and species aggregates. Note that the Swedish Red List 2025 dataset published at the Swedish National Data Service (https://doi.org/10.5878/2x1z-jm10) contains only taxa that were treated as species during the Red List assessments, and consequently differs from this dataset which includes all taxon ranks.
