Under the IUCN Red List criteria, each species is allocated to one of the following categories, relating to imminent risk of extinction: Critically Endangered (CR), Endangered (EN), Vulnerable (VU), Near Threatened (NT), Least Concern (LC), Data Deficient (DD) and Not Assessed (NA). The assessments of Regional Red List status for Great Britain have been formally approved by the Inter-Agency IUCN Red Listing Group. Country-level assessments and those conducted for non-native (naturalised) species followed the same IUCN Regional Red List Criteria. Whilst there is flexibility within the guidelines to allow these assessments to be made, there is no mechanism for these to be formally approved.
