Release of the 2000 pink checklist is an important landmark for IUCN. it's the first time that listings of animals and vegetation were mixed and the 1st time that the crimson checklist has been produced on CD-ROM. The 2000 crimson record combines new assessments‹including all fowl species, many antelope and bat species, such a lot primates and sharks, all Asian freshwater turtles, extra molluscs, and plenty of others‹with these from prior courses. the combo of animals and vegetation right into a unmarried record containing tests of greater than 18,000 taxa (11,000 of that are threatened species) and the circulation in the direction of more advantageous documentation of every species at the record signifies that a hard-copy model of the purple checklist could run to numerous volumes. This, mixed with the truth that the pink record can be up to date every year, ended in the choice to free up the purple checklist in digital structure, through the realm broad internet and as a CD-ROM.

This increase is partly due to a revised taxonomy, but in many cases they are genuine changes brought about by increased habitat loss and hunting. e. an increase from 29 to 46 Endangered species and 13 to 19 Critically Endangered species. For the birds, the most significant changes have been in the Procellariformes (albatrosses and petrels) which have increased from 32 to 55 species (all 16 species of albatross are now listed as threatened whereas in 1996 there were only 3—this is due to the impact of longline fisheries) and the Sphenisciformes (penguins) which have doubled in number from five to ten.
As populations are disappearing in Southeast Asia, there are disturbing signs that the focus of the harvest will shift to the Indian Subcontinent, and perhaps even further afield to the Americas and Africa.

Then follow Colombia, China, Peru and India with 78, 76, 75 and 74 species respectively. The overall results are very similar to those for 1996 with all the same countries appearing except for Papua New Guinea (32 species) which is now replaced by Tanzania (33 species). The ranking of the countries has changed because of increases in numbers of threatened species. The countries with by far the highest percentage of threatened species are New Zealand and the Philippines with 42% and 35% respectively, which matches the findings in 1996.
