There is an additional category – LowerRisk/conservation dependent (LR/cd) that was used in an earlier version of the Red List Categories (IUCN 1994a) but has subsequently been dropped (IUCN 2001). This category was used to indicate species that would be listed as threatened were it not for species-specific conservation programmes. 2), and until such time as these are all re-evaluated, this category will persist as an artefact of the previous classification system. 2a). 1 Mammals, Birds and Amphibians The 1996 IUCN Red List (Baillie and Groombridge 1996) featured complete evaluations for all of the world’s bird and mammal species.
2). The evaluations have tended to focus on particular taxonomic groups that are well known (the crocodilians, turtles, iguanas and tuataras) or on species in the more poorly known groups (lizards and snakes) that are considered to be under threat. Of the species evaluated, 61% are listed as threatened. Two reptile orders have been completely evaluated, namely the Crocodylia (crocodiles, alligators and caimans) and the Rhynchocephalia (tuataras). The Crocodylia have ten (43%) of their 23 described species listed as threatened.
2 The Decline of Turtles The very rapidly deteriorating status of tortoises and freshwater turtles in Southeast Asia has resulted in an increasing number of these species being listed as threatened on the IUCN Red List. Globally, 42% of turtle and tortoise species are threatened. 12 The Anegada Ground Iguana Cyclura pinguis (Critically Endangered) was once distributed over the entire Puerto Rico Bank, but today is confined to the island of Anegada, British Virgin Islands. Vulnerability to predation by humans and their dogs and cats may have resulted in the contraction in range.
