THIRD OF PRIMATES 'RISK EXTINCTION'
By Alex Kirby
Monday, 7 October, 2002
One-third of the world's primate species now face a serious risk of
extinction, according to a report by an international group of
They say the number of threatened species has risen sharply in the last
Primates living in two south-east Asian countries are said to be especially
endangered. But several species are judged a little safer than they used to
The report is entitled Primates In Peril: The World's Top 25 Most Endangered
Primates. It is published by Conservation International (CI) and the primate
specialist group of IUCN, the World Conservation Union.
The authors say the numbers of primate species and sub-species classified as
either endangered or critically endangered have risen nearly 63%, from 120
to 1995, since the publication of an earlier report at the beginning of
Primates include apes, monkeys, lemurs and some lesser-known species.
Scientists say they are our closest living relatives. Nearly 45% of the
world's most endangered primates live in Asia.
The president of CI, Russ Mittermeier, said: "Of particular concern is the
situation in Vietnam and China. With several primates now numbering only in
the dozens or low hundreds of individuals, Vietnam is at risk of undergoing
a major primate extinction spasm within the next few years if rapid action
is not taken.
"Twenty per cent of the top 25 primates are located in Vietnam, with another
16% from China and 12% from Indonesia."
He told BBC News Online: "Human pressures are more intense in these places;
hunting in particular, both for meat and medicinal purposes, is hammering
Of the 25 species listed, 23 are found in the world's "biodiversity
These are regions identified by CI which are home to more than 60% of all
terrestrial plants and animals, although together they cover only 1.4% of
the Earth's land surface.
Six hotspots are judged the highest priorities for the survival of the most
They are Indo-Burma, Madagascar, Sundaland (the islands of Sumatra, Java and
Borneo), the Guinean forests of West Africa, the Atlantic forests of Brazil,
and the western Ghats/Sri Lanka.
Bill Constant of CI, co-author of the report, said the list of the top 25
was just the tip of the iceberg. He said: "For each primate on it, any one
of several other equally endangered species might have been chosen instead."
Praise for Brazil
The main cause of the primates' decline, the report says, is habitat loss
caused by the clearing of tropical forests.
It calls hunting "an insidious and major threat, especially in Africa and
Asia. Once done mainly for subsistence purposes, it has now taken on a major
But the capture of animals for the pet trade and medical research "have
become lesser concerns".
The report says primates are important for ecosystem health, because they
disperse fruit seeds and the remains of other food they eat.
"It's important to mention that it is not all doom and gloom," Russ
Mittermeier told BBC News Online.
"There's some good stuff going on, especially in Brazil and Madagascar --
and some of the species that were on the list last time have been taken off
because they are doing better and some that are still on the list are in
fact getting a lot of attention.
"The technologies and the manpower are there to do it; what we need is an
order of magnitude increase in resources so we can do it in many more
