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.

With a chain-saw, he cut off the rhino's valuable horn

This post now on Google News - a time-sensitive link.

All text and photos by Sally Kneidel PhD of http://sallykneidel.com

I was surprised at how simple it was. One of the men put his foot on the drugged rhino's massive horn, pinning the horn to a wooden block on the ground.

Then another guy revved up the chain-saw and sawed the horn off her face, leaving a stump that protruded about 4 inches from the rhino's skin.

A small plastic sheet under the rhino caught all the shavings, which were considerable.

Below, the shavings and the big horn.

The circular stump, head on, looked like a bulls-eye with its dark center.

Then the man with the chain-saw turned his attention to the second smaller horn, and sawed that off too, once again catching all the valuable shavings and flakes. The rhino was awake enough to flinch at that one, which was much closer to her eyes and ears.

The stumps of both horns on the mother rhino.

Rhino horns are made of compacted hair, so removing one shouldn't hurt if the growth zone at the base isn't touched. The horn will regrow about 2 inches a year, maybe twice that much if the animal is given protein supplements. A typical horn on an adult white rhino is about 22 inches.

As she lay on the ground, the rhino was grunting softly, laboring to breathe. Feeling the urge to comfort, I put my hand on her shoulder. Her skin was tough, like it looked, but I was surprised at how warm it felt- even warmer than human skin. No wonder they have so many parasites, the blood must be right under the surface.

Ken and I had been invited on this rhino capture by a couple of science friends while in Africa, in June. We'd watched while a helicopter took off with a vet, a vet tech, and a pilot to locate two rhinos from the air and to fire a tranquilizer dart from a rifle into each one.

One of the darts, after it was removed.

After a mother rhino and her year-old-baby were located and successfully darted, Ken and I and a group of other scientists had to find the fallen beasts in the dense African bush, not an easy task. The rhinos ran quite a ways before the drug brought them down. The plan was to take samples and measurements from the sedated pair, then inject an antidote to wake them and lead them into two cages on a flatbed truck.

The reason for the capture was that the rhino and her baby had been sold. They were moving from a wildlife preserve into private hands, to raise money for the preserve. The new private owner had requested that the mother have her horn removed to protect her from poachers. I had mixed feelings about that.

The new owner was operating under the theory that a rhino without horns is less likely to be killed by poachers, which may or may not be true - I don't know. Rhino poaching is a real danger, having increased in southern Africa 3-fold between 2005 and August of 2009. In Kruger Park alone, 27 rhinos have been killed in 2009. Rhino horns stored at Addo National Park were stolen in a violent armed robbery in July of '09. Just last night I got an email from a friend in South Africa that "Heidi," the only white rhino at Thula Thula preserve, has just been shot and killed by poachers who hacked off her horn.

Rhino horn is extremely valuable, for two main markets. It's sold to Asian countries, especially China, Taiwan, and South Korea, for use in traditional medicines. And it's sold to Middle Eastern countries such as Yemen and Oman, where it's used to make ornately carved handles for ceremonial daggers. We were told, while in Africa, that much of the rhino poaching is instigated by well-organized Asian syndicates, which may hire impoverished locals to do the dirty and dangerous work. It may take 3 days to track a rhino - which is invariably shot and killed before the horn is sawed or hacked off. An average-sized horn can sell for $24,000 on the black market. The scientists we went out with said the horns sell for $6,000 per kilo, and the mama's horn that we saw weighed about 4 kilos.

So, does removing the horns protect rhinos from poaching? We were told by a variety of sources, including rangers and poaching guards, that removing horns from a rhino does little to protect it. Poachers will still go after a dehorned rhino and shoot it, because even the stump is valuable. And if the stump too is gone, we heard, the trackers will kill the rhino just so they won't waste 3 days tracking the same useless animal again.

So back to the scene... the drugged mama and baby rhino.... as soon as we located the darted rhinos lying down and sedated, the group of scientists on the ground split into two teams to work respectively on the mother and baby. Cloths were tied around their eyes as blindfolds. A soft cloth ball the size of a tennis ball was stuffed into each ear to shut out sounds, to keep the animals calm.

Above, ear plugs for the mother (the black balls), put in place before the sampling and cutting began.

The teams took blood, hair, skin, and tissue samples, measured the animals' temperature and pulse, inspected the teeth and various other body parts, and clamped ID tags to their ears.

Below, the sampling materials in the truck before the work began.

The pulse is checked (below).

One graduate student plucked green Amblyoma ticks from around each rhino's anus. Below, the round ticks are visible in the skin creases. The mother's tail is in the lower right of the photo below. I'm not sure what the white stuff is, maybe an antiseptic or pesticide.

The ticks on most of their skin are plucked off by oxpeckers - birds that specialize in eating external parasites from large African herbivores. But I guess the birds can't get to an anus that's covered by a tail. I like almost all animals, including invertebrates, but I have to admit that the dozens of ticks around the mother's moist anus were a bit unsavory.

It was during this sampling and measuring that the mom's horns were sawed off. The shavings and flakes, which were considerable, were saved because of their value. We were told that they will be stored in a secure vault. For what, or until when, I don't know.

After all the sampling was done, a vet injected the antidote into the 10-yr-old mom and her yearling son, leaving the blindfolds in place.


After just a couple of minutes, the rhinos started to wake up. A bunch of people started trying to roll the rhinos so that their legs would be under them (the mother, below).


The rhinos were then urged and pushed and pulled into a sitting position (the mother, below).


Then the two animals were pulled and prodded toward the cages and truck that would take them to their new home (the mother, below).




As I ran beside the mother rhino, she passed saplings - and trampled them. She didn't go around anything, but smashed everything in her way. Of course she couldn't see where she was going. I felt sorry for her - she had no idea where her baby was, unless her keen sense of smell told her.

We soon arrived at the cage for the mother. She was pulled with the rope, and pushed from behind , and walked easily enough into the cage.


The heavy cage door was lowered by a crane, and then the crane lifted the cage onto the flatbed truck. The baby was already in his cage on the truck, which had room for both cages (below).


Then it started to drizzle. So instead of driving the rhinos 80 some miles in a drizzle and risk their getting a respiratory infection, the decision was made to release them temporarily into a nearby holding pen that was forested and quite extensive. We drove there, the crane put the cages on the ground, and the blindfolds and earplugs were removed. Mom and babe were both released, and the rhinos rejoined one another immediately (below).


They then began to trot away from us (below).

But baby stopped, and turned around to stare at us.

"What the heck was that?," he must have wondered. He may have never seen a human before. Someone clapped and yelled to shoo him and he turned to follow his mother (below).


Rhino conservation: the good and the bad
I didn't know when we were in Africa how threatened or endangered the southern white rhino is. As it turns out, they are classified as Near Threatened (NT) on the IUCN Red List. I did know that they're the largest land animal, after the African and Asian elephants. They're larger than any other rhino species. We saw them on lots of outings in reserves - they were fairly common in southern Africa. I knew that white rhinos are really named for their "wide" and squarish upper lip. Africa's black rhinos, which are much more rare and may be extinct in the wild, have a narrow prehensile upper lip that they use for browsing. Black rhinos are particularly vulnerable to poaching because they must have water daily and they return to the same water hole every day. Sometimes water holes are poisoned to kill the rhinos (and everything else that uses it).

Although the white rhino population in southern Africa is doing relatively well at present, they almost went extinct. In 1895, there were only 20 to 50 animals alive in the wild. Today, the population of white rhinos in southern Africa has grown to 17,500, with 750 more in captive breeding programs around the world, according to ARKive. I don't know how they got from 50 to 17,500, but it's a nice success story.

Still, white rhinos remain in danger due to habitat loss, the recent surge in poaching, and widespread poverty which affects human priorities. Africa is the only continent where poverty is increasing, due to human population growth, recurrent droughts, HIV, and a history of colonization and exploitation.

Poverty is a contibuting factor
In some of the rural villages we visited in southern Africa, we were told that local people often enter national parks illegally to poach wildlife for food or for sale, and to gather firewood to use or to sell, when nearby sources are depleted. It's the hierarchy of needs....if your kids are hungry, you do what you need to do to feed them. If you can. We also heard that rhino poachers are often shot on sight by poaching patrols. You can tell a rhino poacher, we were told, because they carry high caliber rifles - not the snares and homemade traps that local people use to catch smaller animals.

But the main driver of rhino poaching is the demand in consumer countries
Recently, Vietnamese operators have been especially active in poaching rhinos from southern Africa, or in hiring local people to do it. That's according to Traffic, an international NGO that monitors illegal trade in wildlife. David Newton of Traffic reported that "very senior members of the Vietnamese government claim to have been cured of certain terminal diseases by the use of rhino horn......so that seems to be where the demand is coming from." Newton added that rhino horn has no medicinal qualities. It's hard for me to stomach the news that government officials are promoting the poaching of rhinos. Do they know that rhino horns are no different chemically than hair??

A white rhino with its horns intact.

Do rhinos need the horns?
As I watched the mother rhino and her youngster led through this bewildering series of events that left the mother hornless, I wondered about their safety. Doesn't she need her horn to protect the baby from predators? Maybe. But we were told, and observed for ourselves, that rhinos will trample whatever they want to trample. The trampling is more likely to kill you than the horn. Each dangerous animal has its way. A Cape Buffalo will pick you up with its horns and toss you into the air. A hippo "will bite you in half" we heard, if you get between the hippo and its river. But a rhino will just run right over you as though you weren't even there. Each animal deserves distance and respect for different reasons! Rhinos do use their horns in social confrontations, but usually only in slight horn butting, false charges, and displays.

As the two wandered off into the trees after their ordeal, neither mom nor baby seemed to pay any attention to the absence of her horn - but who knows what was in her mind...or what their future will be. At least, I feel confident that she won't wind up on a "trophy" shooting reserve. For who would pay thousands of dollars to hang a rhino head with a bulls-eye stump on his living room wall?

Post script from a friend at TRAFFIC:
After I wrote this post, I got this e-mail from friend and colleague Richard Thomas, who works for TRAFFIC The Wildlife Monitoring Network:
"You may have seen that we [TRAFFIC] submitted a technical document, with WWF and
IUCN, to CITES in July, highlighting the sudden alarming urge in rhino
poaching — and issued a press release about its main findings that got
a lot of publicity. The release is here, where you can download the
report too:

http://www.traffic.org/home/2009/7/9/poaching-crisis-as-rhino-horn-demand-booms-in-asia.html

Vietnam is certainly emerging as the country that's driving the rhino
horn demand. Whilst you're right to flag that poverty is a significant
factor in poaching of animals, research by TRAFFIC indicates that the
main driver is actually the demand for the products in the consumer
countries; and the Vietnam situation appears to be following that model."
I amended my post above slightly after receiving this helpful point from
Richard Thomas.

One African Family Struggles to Survive

Photo courtesy of www.womenaid.org

I want to go to Africa. There is little that I want more, other than the health of my children.

For someone who loves wildlife and is intrigued by cultures different from my own, what destination could be more compelling? The fact that Africa's ecosystems are in serious peril makes me all the more desperate to get there before it's too late. I read yesterday, in an article from Emmanuel Koro of the World Resource Institute, that African conservation areas like Kruger National Park could risk losing up to 60% of their species as a result of the coming climate change.

But ecological changes will impact human communities just as much as the they affect the natural world. The early stages of climate change already exacerbate sub-Saharan Africa's pervasive and increasing poverty, through drought and subsequent crop failure as well as degradation of natural resources.

Poverty is one result of natural resource depletion and degradation, but poverty also causes resource depletion. Some of these causes are obvious, some less so. For example, poverty together with political instability means that social programs to improve options for women are often grossly underfunded. Women without access to education, health care, and employment, and the autonomy those opportunities bring, tend to marry in their teens and have large families. Larger families lead to rapid population growth and contribute to the consumption of natural resources at unsustainable rates. The high rate of HIV infection in sub-Saharan Africa also contributes to increased reliance on forest resources.

Poverty feeds habitat destruction; habitat and natural resource depletion feed poverty.

The problems facing sub-Saharan Africa are daunting.

Below, from the World Resource Institute, is a profile of one family's struggle to make a living, to survive, as forest resources dwindle. Their plight is difficult to fathom in the relative comfort of our 2200 sq ft (average) American home. But it puts a face on the challenges of rural life in an impoverished nation with an average income of less than $2 per day.


Fueling Malawi’s Environmental Challenges

by Charles Mkoka

(Blantyre, Malawi, February 2004) At 2:30 in the afternoon the Dyeratu family has just clambered down one of the highest mountains near Blantyre, the commercial capital of Malawi. Idan and Feligasi Dyeratu and their daughter, Gertrude, began the trek up the 1,400 meter-high Mount Michiru at sunrise on empty stomachs. Eight hours later and a little more than half way home, they have stopped to take a rest under a Eucalyptus tree, each burdened with a load of firewood that they carry on top their heads.

As Blantyre has grown in size and population -- almost tripling in the past decade -- the forests that blanketed the two mountains around the city have been under increasing pressure. Already the trees shrouding Ndirande Mountain have been entirely cleared for fuel wood and brick making. Families are now hiking to the forests on Michiru for their fuel.

In Malawi, 93 percent of energy comes from fuel wood. Under this pressure, deforestation is not just an ecological threat; women are negatively affected as well. Traditionally, it is women's work to gather wood for cooking. Increasingly, they have to walk long distances to gather firewood. This has consequences for the entire family: as firewood becomes scarce, the nutritional status of families often declines. Limited supply of fuel and energy forces many families to reduce the number of meals they eat and to prepare food that requires less cooking, which is often less nutritious.

Idan says his family climbs the mountain every Saturday so he can sell the wood in the densely populated township of Chirimba. They purchase loads of firewood from forestry officials that are managing a plantation on Mount Michiru. "The exotic pine plantation is benefiting us a lot," said Idan. "I make a profit of about 400 Kwacha [about US$4] per head load carried down the mountain after buying it at 15 Kwacha from forestry officials."

A recent survey conducted by the Wildlife and Environmental Society of Malawi identified poverty as both a major social problem faced by local people, and as a serious cause of pressure on the environment in Malawi. According to William Chadza, head of the organization's natural resources management program, poverty and lack of resources "lead the people to use available natural resources unsustainably."

Chadza cites charcoal production as an example. Around the country, rural communities are rapidly burning their forestlands to produce charcoal, which is in high demand in cities. To make 50 kilograms of charcoal requires 250 kilograms of wood. The disappearance of forests has resulted in massive soil erosion and siltation in low-lying areas resulting in floods during heavy rains. Increased flooding and siltation not only threatens rural communities, it has disrupted operations at the biggest hydroelectric dam in the country, resulting in power outages.

The UN's 2000 Human Development Report ranks Malawi as one of the 10 poorest countries in the world -- 163 out of 173 nations. About 65 percent of the people live below the poverty line, and 28 percent suffer from "severe poverty."

Malawi has a population of about 12 million, with most of the population living in rural areas. Nearly 85 percent of the population is dependent on agriculture, and in 2002 more than half of those people were not able to produce enough food to feed themselves the entire year.

While the country has taken measures to address poverty -- launching a poverty-monitoring system to inform and oversee poverty related issues -- the rapidly growing population continues to exert pressure on the country's natural resources. Until recently, Malawi was home to more than a million refugees from Mozambique refugees who fled armed conflict in their country a decade ago. Further, an influx of firearms from the conflict has helped poachers finish off elephants in Majete wildlife reserve and the Black Rhino in the Mwabvi Wild reserve.

Like the Dyeratu family many people now earn their living by selling fuel wood and charcoal. Idan says business of selling firewood assists his family to buy necessities like food, soap and salt and supports five of his children, who attend primary school and secondary education. However he is not sure what the future holds, when resource that he collects from Michiru Mountain is exhausted. "If the forest officials stops selling firewood from the mountain, then we have to decide as a family, what we have to do," said Idan. (WRI Features, 730 words)

In later blog posts here, you can read how conservation organizations such as The Nature Conservancy in partnership with the African Wildlife Foundation, the Jane Goodall Institute, and the Green Belt Movement are working to develop incentives to help rural Africans protect natural resources in ways that also support their families. The challenge is immense, but the progress is encouraging. Because poverty and resource depletion are so intricately linked, any solution must address both. To be in some way a piece of that solution......what could be more gratifying or more meaningful?
