Trade a major threat to primate survival

Tens, if not hundreds, of thousands of primates are traded every year, and the number's been growing linearly for 15 years When I read that news in a recent study by Vincent Nijman of Oxford Brookes University, I was not surprised. Having worked and traveled in Africa, the Amazon, and S.e. Asia, I've seen for myself that legal and illegal trade in primates is rampant. I've communicated with Nijman several times over primate issues; he seems to be one of the most knowledgeable academics alive on the subject of primate trade in S.e. Asia (and maybe elsewhere as well).

Nijman's article ("Primate conservation: measuring and mitigating trade in primates") is the overview article to a new issue of the open-access journal Endangered Species Research. This particular issue is the result of a recent conference and is devoted entirely to primate conservation. In Nijman's introduction, he and co-authors write that the international trade in primates -- for research, pets, meat, etc.-- is one of the biggest threats to primate conservation. Habitat loss and hunting are the main threats to primate survival in the wild, but trade is a leading threat for some species, such as the slow loris and Barbary macaque.

During the 1990s, numbers of wild-caught and captive-bred primates traded were roughly equal, but afterward captive breeding increased substantially.  By 2005, around 71,000 live primates were traded internationally, 53,000 of them reported as captive-bred. However, some of the captive-breds may have been laundered wild-caught specimens.

Since 1995, China and Mauritius have supplied more than half of all primates traded internationally (31% and 18% respectively).  And guess who is the largest importer of live primates? I'll give you a hint - a country with thriving medical research and a poorly regulated pet trade.  Yep, the US imports the most live primates (26%), with Japan (14%) and China (13%) close behind.

Although I knew about the trade in live primates, I was shocked to read in Nijman's paper that more than a million dead primates are traded every year. The trade in dead primates and primate parts includes almost 20,000 exported as hunting trophies over the past 30 years.

The dead also include more than 100 primate species used in traditional medicines (based on cultural superstitions).The journal mentioned above contains a paper by Starr et al. documenting the threat posed to two slow loris species in Cambodia from such trade.

However, the major trade in primates is in those traded domestically for food. A paper by Wright and Priston in this same special issue examines what drives such trade in southwestern Cameroon and concludes that many more primates are sold there for wild meat than are captured for local consumption.

Examples of illegally traded primates include long-tailed macaques from mainland S.e. Asia (Cambodia, Laos, Viet Nam) into China, to supply the booming biomedical trade. A paper in this special issue by Maldonado and co-workers documents the illicit trade of over 4,000 night monkeys (Aotus spp.) each year from Peru and Brazil into Colombia to supply a biomedical research facility.

“The above figures are from an analysis of legal trade reported to CITES [the Convention on International Trade in Endangered Species of Wild Fauna and Flora], but the true figures are likely to be higher, because of under-reporting and illegal trade,” says Nijman.

As Nijman et al. note, in 2006, trade was listed as a threat to only one of the world’s most threatened primates species, but four years later, trade for meat, medicines and pets is implicated in the decline of nine of these species.

Other papers in the special issue include one by Chris Shepherd of TRAFFIC Southeast Asia on the illegal primate trade in Indonesia.  He also contributed as a co-author to an article on gibbons in zoos and rescue centers in Indonesia. Chris is an impressively diligent and persistent wildlife-trade researcher and writer for TRAFFIC in S.e. Asia.  He was a big help to me in preparing for my own travels there.

“The illegal primate trade in Asia is decimating populations of some of the region’s most charismatic species: tackling such trade should be regarded as an urgent priority for wildlife enforcement agencies in the region,” said Shepherd.

Other topics covered include effective implementation of CITES; the use of forensics in trade; problems, pitfalls, and successes of rehabilitating and reintroducing confiscated primates; and educational and livelihood strategies to mitigate trade.

Africa's big mammal populations drop 59% in 40 years!

Just saw a distressing news item.  In an interview published 1/27/11, scientist Ian Craigie says populations of big mammals in Africa have decreased 59% in 40 years. And those figures are only from protected areas such as national parks. If unprotected areas were included in the study, the percent would probably be much higher.  Craigie is a zoologist (University of Cambridge) and former employee of South Africa National Parks.

Craigie says the primary causes of the decline are agriculture, hunting and the bushmeat trade. But all are due to human actions and Africa's population explosion. Africa's human population has increased 5-fold since WWII. The additional human population has moved into cultivated areas that were previously wildlife habitat, leading to widespread habitat destruction.

I might add (my words, not Craigie's) that deforestation for agriculture and timber has increased access to previously secluded or inaccessible wildlife.  Modern weaponry has also increased the ease of killing large numbers of animals for commercial trade as bushmeat or traditional medicine.

Craigie says that Southern Africa is better off than West Africa or East Africa because the parks in Southern Africa have better funding and the human population is less dense.

West Africa has the most serious wildlife problem of the three regions because of the strong tradition of hunting for bushmeat, the countries are poorer, and the human population density is high.

What's the solution? Increase funding for programs to help communities develop livelihoods that depend on protecting wildlife (such as ecotourism) rather than over-harvesting and destroying their greatest resource (wildlife) and their greatest potential for income.  These are my words, not Craigie's.  Americans alone spend 12 billion dollars per year on ecotourism in Africa.

Hunting may threaten orangutans even more than habitat loss

[See bottom of this page for list of my previous posts about orangutans.]

Most people are surprised to learn that unlawful traffic in wildlife and wildlife parts is the third biggest criminal activity in the world, after drugs and arms. The illegal hunting of great apes is so pervasive that it may threaten their survival even more than habitat loss does. Habitat loss is rampant these days, due to human population growth....so I wouldn't have believed that hunting could be an even bigger threat until reading a recent paper by Vincent Nijman (and 5 other scientists). Nijman is a scientist at Oxford Brookes University, a consultant to TRAFFIC, and has published numerous research papers on orangutan conservation.  He and the other authors of this particular paper collected convincing data that suggest orangutan populations have been reduced more by hunting than anything else.

I crisscrossed Indonesia and Malaysia looking for orangutans

I was on the islands Borneo and Sumatra a few months ago, searching high and low for wild orangutans. That was my main reason for going to Southeast Asia.  I had researched sites carefully in advance and I chose my destinations accordingly; consequently, I was lucky enough to see a number of wild orangutans in undisturbed forests. But as Dr. Nijman writes, "Bornean orangutans currently occur at low densities and seeing a wild one is a rare event." In contrast, historic collectors like Alfred Russel Wallace in the 1800s saw many orangutans daily and "were able to shoot continuously over weeks or even months."  Clearly, orangutans are much rarer today than they were in the past. That's true not only of orangutans, but also for the other great apes.

Chimpanzees and gorillas are hunted for meat

I saw on the "Planet Green" network on November 24 a one-hour documentary about an investigation into the hunting of chimpanzees and gorillas for bushmeat in Cameroon. The investigator, Steve Galster, said these two apes are popular meat because they're so big and fleshy relative to other remaining wildlife. The primary reasons they're shot or trapped is to eat them, to sell their meat to neighbors, or to transport the meat by train or car to city markets. But when baby animals are captured after shooting the mother, the babies can be shipped abroad to be sold as pets. So killing a mother ape is doubly profitable.

A pet chimp brings social status

I was impressed with the diligence of the filmmakers for this Planet Green show, which featured an undercover sleuth (a local woman) equipped with a tiny concealed camera visiting a local man who was trying to sell a baby chimp. The chimp was eventually confiscated and sent to a sanctuary. Even at the sanctuary, though, young chimps are vulnerable to theft in order to sell them. The demand for them is huge.

Having a baby chimp is a social asset, the narrator said - something to show off no matter where you live. I can imagine that. There aren't many things in life more interesting than a living baby ape. In this Planet Green documentary, the poachers and smugglers who were caught on film all wound up going free, through "negotiations" (bribery) or police who failed to show up in court, or officials who took pity on impoverished poachers and their children.

Strong evidence that hunting has hurt orangutans more than habitat loss

The research of Vincent Nijman (and 5 colleagues) into the hunting of orangutans on Borneo was published in the online journal PLoS ONE in August, 2010. The researchers used "encounter rates" to measure the density of orangutans over the last 150 years in a variety of different habitats on Borneo. Their data came from hunting accounts, museum collections, and field studies. By the researchers' calculations, the number of Bornean orangutans has declined about 6-fold since the mid-1800s. The convincing aspect of their data is this: If large-scale deforestation and forest degradation caused the decline, then we would expect to see a sudden decline after the 1960s and 1970s, "coincident with major intensification of [deforestation] during this period." However, encounter rates declined steadily for at least 120 years before major deforestation began. Furthermore, say Nijman et al., although orangutan numbers do generally decrease following habitat disturbance, they manage to survive in high densities in some areas that have been heavily disturbed or even clear-cut and planted with monoculture plantations. Nijman et al. also noted that local orangutan extinctions or historical declines have occurred in the same areas where we know orangutans have been heavily hunted.

Orangutans now extinct in upland Borneo, where hunting was heavy historically

Mother and infant orangutan on Borneo.  Photo: Sally KneidelFor example, orangutans have long been extinct in upland areas of Borneo where poor soil prevents farming - areas that were historically populated by nomadic humans forced to rely on hunting. In contrast, freshwater and peat swamp environments were mostly not inhabited by people until the 19th century, but were densely populated by orangutans. The PLoS ONE paper sites many other examples of hunting-related distribution patterns of orangutans. In eastern Sabah (a state in Borneo), roving bands of head-hunters provided a refuge for orangutans and other wildlife, because other humans were afraid to enter the area. That refuge ended when head-hunting was banned.

Nijman et al. conclude that hunting has been underestimated as a key causal factor of orantugan density and distribution, and that orangutan population declines have been more severe than previously estimated based on habitat loss only.

Why do people still hunt orangutans?

The red apes, among our closest relatives, are still hunted for food or traditional medicines, as agricultural pests, for trophies, and more recently, for the pet trade. When I was in Southeast Asia in June and July, I visited the wildlife markets of Jakarta, where vendors openly flaunt wildlife-protection laws that are seldom enforced. There I was offered pet orangutans, along with many other supposedly protected primates, protected birds, and even a baby jaguar. Many told me they were carrying on a family business that had been handed down by their fathers. For more about my time in the Jakarta markets, see this post.

Trapping, shooting, eating, and selling wildlife are long-held traditions in forest cultures. Solutions must involve enforcement of local laws protecting forests and wildlife, and enforcement of penalties. That's something that's not happening right now in developing countries. But it must if orangutans, gorillas, chimpanzees, tigers, and thousands of other species are to survive this century. Many organizations are busy, on site, trying to make it happen. In Southeast Asia, TRAFFIC and Greenpeace are working hard to turn things around.

What can you do?

Support some of the NGOs who are making the most progress in protecting orangutans from illegal hunting and trade and who are fighting to protect Southeast Asia's remaining forests from destruction.

These are some of the best:

Greenpeace International
TRAFFIC: the wildlife trade monitoring network
ProFauna (an Indonesian NGO that helped me in Jakarta by providing a local guide to go with me to the markets)
World Wildlife
ForestEthics
Rainforest Action Network
