The World's Top 25 Most Endangered Primates- 2002

A recent report released by Conservation International (CI) and the Primate Specialist
Group of IUCN was finalized at the 2002 International Primatological Society meetings
in Beijing. 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.

The Sanje mangabey, endemic to the Udzungwa Mountains of Tanzania, is a relatively recent arrival on the list of African mammals, only having been discovered in 1981. It differs from other closely related mangabeys in fur coloration (being a smoky brown or fawn color with a lighter, almost buffy orange underbelly) and facial coloration (beige with white eyelids). Found only in fragmented relict forests of the Udzungwas, it may prefer riverine habitat at altitudes ranging from 400-1,600 meters, although it is probably more common above 1,000 meters. At least one sub-population resides within the recently established Udzungwa Mountains National Park, but it is also known to occur in low densities outside the protective boundaries of the park in the Ndundulu and Udzungwa Scarp Forest Reserves, where animals are at risk due to hunting and habitat loss. Overall, fewer than 1,500 of these primates may exist. The University of Georgia and Duke University are collaborating on a field research program in the Udzungwas to determine the extent of this mangabey's distribution, and are using this information to develop a recommendation for expanding the present boundaries of the national park.
