This organization seeks to limit global extinctions, both plant and animal, by bringing together international biodiversity groups to identify the most vulnerable areas. There is a lot of interesting information on their website.
The interactive map is an interesting place to explore with clickable sites. I clicked on a site in Bermuda and found that there are no endemic mammals or amphibians. The one reptile, the Bermuda skink is the only native land vertebrate other than birds. The two endemic birds are the Cahow or Bermuda petrel and a race of the white-eyed vireo. The forests of Bermuda are filled with endemic trees including the Bermuda Cedar (Juniperus bermudiana).
