The IUCN Red List (2004) documents the extinction of 784 species (including 338 vertebrates, 359 invertebrates and 87 plants) in the last 500 years. Some examples of recent extinctions include the dodo (Mauritius), quagga (Africa), thylacine (Australia), Steller’s Sea Cow (Russia), and three subspecies (Bali, Javan, Caspian) of tiger. The last twenty years alone have witnessed the disappearance of 27 species. Careful analysis of records shows that extinctions across taxa are not random; some groups like amphibians appear to be more vulnerable to extinction. Adding to the grim scenario of extinction is the fact that more than 15,500 species worldwide are facing the threat of extinction. Presently, 12 percent of all bird species, 23 percent of all mammal species, 32 percent of all amphibian species, and 31 percent of all gymnosperm species in the world face the threat of extinction.
