Focal Species

The EDGE of Existence programme is supporting conservation projects for ten of the top EDGE coral species.

These species have been selected for conservation attention at an international workshop because they are extremely evolutionarily distinct and threatened, and are currently receiving little or no conservation attention from other organisations.

We feel that we are in a position to truly make a difference to the future of these species.
