It is a revision of their previously released "The World's Top 25 most Endangered Primates", which indicates that about one out of every three primate species is currently threatened with extinction. This updated version suggests that Indonesia now exceeds Madagascar and Brazil for the country with the most endangered primates. However, Madagascar, identified as one of the world's biodiversity hotspots, has 10 critically endangered species, and 21 endangered species. For the full report, please refer to the link at the bottom of this message. Each week, we will be featuring one of the 25 primate species in peril. This is being done in conjunction with Conservation International. The fact sheets are compiled by Sean Flannery at the WPRC Library and Information Service. Golden-headed Langur Trachypithecus poliocephalus Vietnam This rare Asian colobine monkey is presently known only from Cat Ba, the largest of more than 3,000 islands located in northeastern Vietnam's Halong Bay. Cat Ba is a series of karst outcroppings largely covered by forest, with a terrain too rocky for agriculture. Island inhabitants make their living traditionally from the sea and more recently from a growing tourism industry. This monkey sometimes winds up in the cooking pot, but its bones and organs are more eagerly sought for their reputed medicinal properties. As a result, hunting remains a serious threat. Over the course of the last year, golden-headed langur numbers on Cat Ba are reported to have dropped precipitously from more than 100 to an estimated 60 or so. While much of the island falls within Cat Ba National Park, not all the langur groups reside within its boundaries and protection from poaching remains problematic. Some of the surviving monkeys can occasionally be seen in early morning or late afternoon amidst low vegetation that grows on nearly vertical rock cliffs that face the sea, thus there is some potential for using tourism to secure their future. Dr. Rosawitha Stenke (Allwetter Zoo Muenster and the Zoological Society for the Conservation of Species and Populations) has been stationed on Cat Ba for the past few years and is heading up both protection and public awareness efforts in collaboration with Vietnamese authorities and with support from Conservation International. In addition, protection of the golden-headed langur has been designated a priority project of Fauna and Flora International's newly-created Flagship Species Fund.
