Rødlisten

Rødlisten refers to Norway’s official Red List of threatened species and habitats. The list provides a scientific assessment of the conservation status of native species and habitat types, documenting population trends, geographic distribution, and known threats. It is produced by Artsdatabanken, the Norwegian Biodiversity Information Centre, on behalf of the government, with input from researchers, museums, nature organisations and other experts. The assessments follow standardized criteria derived from the IUCN Red List system and categorize taxa and habitats into levels such as Critically Endangered, Endangered, Vulnerable, Near Threatened, and Least Concern, as well as Data Deficient and Not Evaluated, and the occasionally used extinct categories.

The Red List covers both species (arter) and natural habitat types (naturtyper). For species, it includes plants, animals, fungi and microorganisms that occur in Norway; for habitats, it evaluates the risk to distinctive ecological communities and landscape types. The Red List serves as a tool for prioritizing conservation actions, guiding nature management, and informing policy, public awareness, and funding decisions. It is used by national and local authorities, researchers, landowners and NGOs.

Rødlisten is updated periodically as new data become available. Updates involve data gathering, expert review and revisions of status and threat factors, reflecting changes due to factors such as habitat loss, climate change, invasive species and improved knowledge.
