More than 100,000 rare gorillas found in Congo

(CNN) -- An estimated 125,000 Western lowland gorillas are living in a
swamp in equatorial Africa, researchers reported Tuesday, double the
number of the endangered primates thought to survive worldwide.

Researchers have revealed the discovery of 125,000 Western lowland
gorillas in northern Congo.

"It's pretty astonishing," Hugo Rainey, one of the researchers who
conducted the survey for the U.S.-based Wildlife Conservation Society,
told CNN Tuesday.

The last census on the species, carried out during the 1980s,
estimated that there were only 100,000 of the gorillas left worldwide.
Since then, the researchers estimated, the numbers had been cut in
half.

WCS survey teams conducted the research in 2006 and 2007, traveling to
the remote Lac Tele Community Reserve in northern Republic of Congo, a
vast area of swamp forest.

Acting on a tip from hunters who indicated the presence of gorillas,
Rainey said that the researchers trekked on foot through mud for three
days to the outskirts of Lac Tele, about 80 kilometers (50 miles) from
the nearest road.

"When we went there, we found an astonishing amount of gorillas," said
Rainey, speaking from the International Primatological Society
Congress in Edinburgh, Scotland.

Though researchers did spot some gorillas, they based their estimate
on the number of gorilla nests found at the site, Rainey said. Each
gorilla makes a nest to sleep in at night.

"This is the highest-known density of gorillas that's ever been
found," Rainey said.

Western lowland gorillas are listed as critically endangered, the
highest threat category for a species. Their populations are declining
rapidly because of hunting and diseases like ebola hemorrhagic fever,
whose symptoms include diarrhea, vomiting and internal and external
bleeding.

While the discovery in northern Congo indicates that the gorilla
population remains stable in some areas, it is likely that gorillas
will remain critically endangered because the threats facing the
species are so great, Rainey said.

"We know very little about ebola and how it spreads," he said. "We
don't even know the animal that spreads it around."

The goal now, Rainey said, is to work with the Congolese government
and donors to protect the areas in which the gorillas are known to be
living.

Western lowland gorillas, which are found in Cameroon, the Central
African Republic, Equatorial Guinea, Gabon and Nigeria as well as the
Republic of Congo, are the most numerous and wide-ranging of the four
gorilla subspecies, each of which is threatened by extinction, the WCS
says.

Illegal hunting and habitat loss have also threatened the Cross River
gorillas, found in the highlands of Cameroon and Nigeria. Only about
250 to 300 are estimated to remain in the world, the WCS says.

War, habitat loss, poaching and disease are the major threats to the
mountain gorillas, made famous by researcher Dian Fossey and the film
"Gorillas in the Mist." The mountain gorilla population is starting to
recover after decades of conservation work. From a population of
around 230 in the 1970s, the mountain gorillas now number around 700,
the WCS says.

Poaching and war have also threatened populations of Grauer's gorillas
in the eastern Democratic Republic of Congo, the former Zaire. The WCS
estimates their population to be around 16,000.

News of the discovery of the Western lowland gorillas in northern
Congo comes the same week as a report that almost 50 percent of the
world's primates are in danger of extinction.

The report, also delivered to the Edinburgh conference, cites habitat
loss and hunting as the greatest threats. The situation is especially
dire in Asia, where the report says more than 70 percent of monkeys,
apes, and other primates are classified as vulnerable, endangered, or
critically endangered.

Conservation International and the International Union for
Conservation of Nature issued the report.
