    ANTANANARIVO, MADAGASCAR - Mankind’s closest living relatives—the world’s apes, monkeys, lemurs and other primates—face increasing peril from humans and some could soon disappear forever, according to a report released today by the Primate Specialist Group of IUCN-The World Conservation Union’s Species Survival Commission (SSC) and the International Primatological Society (IPS), in collaboration with Conservation International (CI).

    Primates in Peril: The World’s 25 Most Endangered Primates—2004-2006 reveals that 25 percent—or one in four—of the 625 primate species and subspecies are at risk of extinction. The report compiled by more than 50 experts from 16 countries cites deforestation, commercial bushmeat hunting, and the illegal animal trade as the primary threats, and warns that failure to respond will bring the first primate extinctions in more than a century.

    "More and more, mankind’s closest living relatives are being cornered into shrinking areas of tropical forest," said CI President Russell A. Mittermeier, who also chairs the IUCN-SSC Primate Specialist Group. "This is especially true of Madagascar, one of the planet’s biodiversity hotspots that has lost most of its original forest cover. More than half its lemurs, none found anywhere else in the world, are threatened with extinction. Without immediate steps to protect these unique creatures and their habitat, we will lose more of our planet’s natural heritage forever."

    The World’s 25 Most Endangered Primates list, compiled at the 20th Congress of the International Primatological Society in Turin, Italy, follows similar reports in 2000 and 2002. Fifteen of the primates on the new list, including the Sumatran orangutan of Indonesia and the northern muriqui of Brazil, are “three-time losers” for having appeared on all three lists. Seven are new additions to the 2004-2006 list, and three appeared once before.

    Madagascar and Vietnam each have four primates on the new list, while Brazil and Indonesia have three, followed by Sri Lanka and Tanzania with two each, and one each from Colombia, China, Cameroon, Ivory Coast, Equatorial Guinea, Ghana, Kenya, Nigeria, Rwanda, Uganda, and Democratic Republic of Congo. Some primates on the list are found in more than one country.
