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.

Natuna Banded Leaf Monkey
Presbytis natunae

Photo Link:
Indonesia's Natuna Islands, located approximately midway between Borneo and the Malay Peninsula in the South China Sea, are home to a highly threatened and endemic colobine monkey. Originally considered a subspecies of Presbytis siamensis, the banded leaf monkey of North Natuna Island is now regarded as a full species. Unfortunately, little is known about its conservation status. It is reported to survive in a range of habitats, even including rubber plantations. However, no protected forest areas currently exist and pressure on remaining forests continues to grow as the result of ill-planned development and failed trans-migration programs. There is a very strong military presence on Natuna and the island is the site of a large natural gas extraction project. Anticipated profits from gas production might actually provide the opportunity for saving some of the leaf monkey's tropical forest habitat from future logging operations.
