EDGE Lists

The EDGE of Existence programme uses EDGE Lists to prioritise species for conservation. The team produces EDGE Lists for amphibians, birds, corals, mammals, reptiles and sharks and rays (elasmobranchs).

Our EDGE Lists are updated periodically to incorporate changes in both taxonomy and conservation status of EDGE species, and we provide the most recent data for download:

EDGE Lists for amphibians, birds, mammals, corals, reptiles and sharks – the ED scores of all species and the EDGE scores and ranks of EDGE species (species above median ED and VU, EN, CR on the IUCN Red List)

When creating our EDGE amphibians list, we follow the taxonomy of Frost’s Amphibian Species of the World. For birds, we follow BirdLife International. For corals, we follow Corals of the World. For mammals, we follow The IUCN Red List. For reptiles, we follow The Reptile Database.

Note: EDGE Lists are dynamic, and are affected by changes in taxonomy and conservation status. All taxonomic and IUCN Red List data underpinning the 2020 EDGE Lists are correct as of April 2020.
