EDGE species have few close relatives on the tree of life and are often extremely unusual in the way they look, live and behave, as well as in their genetic make-up. They represent a unique and irreplaceable part of the world’s natural heritage, yet an alarming proportion are currently sliding silently towards extinction unnoticed.

Highlighting Priority Species

Baby Slender Loris
Priority mammal, amphibian and coral species have already been identified, and work is now underway to develop EDGE lists for birds and sharks.

The primary goal of the EDGE of Existence programme is to ensure that that conservation is in place for every priority EDGE species within five years of their initial assessment.

EDGE coral reefs highlights 10 priority species for conservation that reflect the rich diversity of an ecosystem often referred to as the ‘rainforests of the oceans’. Saving these species could hold the key to the future adaptation of coral reefs to climate change. Find out more about EDGE Corals

Elephants, rhinos and pandas are well-known EDGE mammals, but 70% of the highest priority species remain poorly-understood, such as the venomous Hispaniolan solenodon and egg-laying long-beaked echidnas, which are in urgent need of conservation attention. Find out more about EDGE Mammals
