Wild orangutans at Borneo National Park

Wild orangutans have little room left to

maneuver. Their forest homes are shrinking at an alarming rate and

their future is on the line.

Orangutans are large red haired arboreal

great apes. They can live up to the age of 50 years, and are regularly

observed using objects in the forest for tools.

They are only found in

natural rainforest habitats on the islands of Borneo, where they are

classed as endangered, and on Sumatra, in Indonesia, where they are

critically endangered.

Estimates are that between 45,000 to 69,000

orangutans remain in all of Borneo and about 7,300 in Sumatra; but the

figures are based on those collated over three years up to 2003, and

scientists predict the numbers are in fact far lower. (EPA)
