World's most endangered primates revealed

Nearly half of all primate species are now in danger of becoming extinct according to a new report �Primates in Peril: The World's 25 Most Endangered Primates 2008�2010'. Of the world's 634 primate species 48% are classified as threatened with extinction on the IUCN's 'red list' of threatened species. The report compiled by 85 experts from across the world reveals the main threats are habitat destruction particularly from the burning and clearing of tropical forests the hunting of primates for food and the illegal wildlife trade. The list includes five primate species from Madagascar six from Africa 11 from Asia and three from Central and South America all of which are the most in need of urgent conservation action.Conservationists want to highlight the plight of species such as the golden headed langur (Trachypithecus p. poliocephalus) which is found only on the island of Cat Ba in the Gulf of Tonkin north-eastern Vietnam where just 60 to 70 individuals remain. Similarly there are thought to be less than 100 individual northern sportive lemurs (Lepilemur septentrionalis) left in Madagascar and around 110 eastern black crested gibbons (Nomascus nasutus) in northeastern Vietnam.The list has been drawn up by primatologists working in the field who have first-hand knowledge of the causes of threats to primates.The results from the most recent IUCN assessment of the world's mammals indicate that primates are among the most endangered vertebrate groups says Dr Russell Mittermeier Chair of the IUCN/SSC Primate Specialist Group and President of Conservation International. The purpose of our Top 25 list is to highlight those that are most at risk to attract the attention of the public to stimulate national governments to do more and especially to find the resources to implement desperately needed conservation measures. We want governments to commit to desperately needed biodiversity conservation measures when they gather in Japan in October. We have the resources to address this crisis but so far we have failed to act.Despite the gloomy assessment conservationists point to the success in helping targeted species recover. In Brazil the black lion tamarin (Leontopithecus chrysopygus) was down listed to Endangered from Critically Endangered on the IUCN Red List as was the golden lion tamarin (Leontopithecus rosalia) in 2003 as a result of three decades of conservation efforts involving numerous institutions many of which were zoos. Populations of both animals are now well-protected but remain very small indicating an urgent need for reforestation to provide new habitat for their long-term survival.
