Some of the great apes - chimps, gorillas, and orangutans - could be extinct in the wild within a human generation, a new assessment concludes.
The World Atlas of Great Apes and their Conservation is published by the UN's environment and biodiversity agencies.
It brings together data from many sources in an attempt to assess comprehensively the prospects for the remaining great apes; the gorillas, chimpanzees and bonobos of Africa, and the orangutans of south-east Asia.
"All of the great apes are listed as either endangered or critically endangered," co-author Lera Miles from the World Conservation Monitoring Centre near Cambridge told the BBC News website.
One critically endangered species is the Sumatran orangutan, of which around 7,300 remain in the wild.
Most live in Aceh province at the northern tip of Sumatra, which saw armed conflict for decades between the Indonesian government and separatist rebels, and which suffered heavily during December's tsunami.
"The irony is that just as things are getting better for the people of Aceh, they're getting worse for wildlife, with people collecting timber, dormant logging concessions being activated, and illegal logging as well," said Dr Miles.
The mountain gorilla of the Democratic Republic of Congo, and the Cross River gorilla, found on the border between Nigeria and Cameroon, are also listed as critically endangered, with numbers estimated at 700 and 250 respectively.
For gorillas and chimpanzees, ebola fever is emerging as a significant threat.
Why ebola is now taking its toll of apes is not clear, but may be connected with forest clearance. One theory is that the as yet unidentified animal which harbours the virus lives on the edges of forests; logging creates more edges, and so enhances the transmission of ebola.
"If we find ways to protect apes from the ebola virus, we also will protect humans," it concludes.
But disease is not the only threat to the well-being of chimpanzees, their close relatives bonobos, and gorillas.
Bushmeat hunting and habitat removal by logging are also major issues.
The World Atlas comes with a foreword by UN Secretary-General Kofi Annan, in which he argues forcibly for the preservation of apes.
"The great apes are our kin," he writes. "Like us, they are self-aware and have cultures, tools, politics, and medicines; they can learn to use sign language, and have conversations with people and with each other.
"Sadly, however, we have not treated them with the respect they deserve."
