Birdlife International Datazone
EBAs contain nearly all of the world's restricted-range bird species – only 7% of restricted-range species do not overlap with other such species and therefore do not occur in EBAs. The EBAs also support many of the world's more widespread bird species. Half of all restricted-range species are globally threatened or near-threatened and the other half remain forever vulnerable to the loss or degradation of habitat owing to the small size of their ranges. The majority of EBAs are also important for the conservation of restricted-range species from other animal and plant groups. For example, there is an overlap of 70% between the location of EBAs and areas which are similarly important for endemic plants globally. The unique landscapes where these species occur, amounting to just 4.5% of the earth's land surface, are high priorities for broad-scale ecosystem conservation.
