Western Australia’s Martu people set small fires as a matter of course while hunting lizards. But the technique may also buffer the landscape against two extremes – overgrown brush and widespread lightning fires – that hurt Australia’s endangered small mammals.
When species start disappearing, it usually makes sense to blame it on the arrival of humans. But in the case of Western Australia’s declining small-mammal populations, the opposite may be true.
The Aboriginal Martu people of Western Australia have traditionally set small fires while foraging, leaving a patchwork landscape that proves a perfect environment for bilbies, wallabies, possums and other threatened mammals.
Stanford anthropologists have discovered that when these controlled burns cease, the desert rapidly becomes overgrown – and a single lightning strike can send wildfires tearing through hundreds of square miles of tinder-dry mammal habitat.
The paper, authored by Stanford anthropology Associate Professor Rebecca Bliege Bird, senior research scientist Douglas Bird, postdoctoral scholar Brian Codding and undergraduate Peter Kauhanen, appeared recently in the journal Proceedings of the National Academy of Sciences.
Hunting with the Martu
Martu Native Title, deep in Australia’s Western Desert, contains some of the most remote human settlements in the world. Parnngurr, a Martu community with a population of around 80, is located more than 200 miles from the nearest mining outpost.
Making the most of the harsh, arid landscape’s resources, the Aboriginal Australians hunt bustard, emu and kangaroo and collect a wide variety of fruits, tubers and seeds. But their most important resource is the sand goanna – a 4-foot long burrowing lizard that accounts for nearly 40 percent of all foraged calories.
The goanna hunt likely hasn’t changed in thousands of years. In winter, when the lizards are hibernating, groups of women head out from the camps and set fire to patches of the spinifex grass covering den entrances.
Once the brush has been cleared, the woman who sets the fire has first rights to dig out any goanna burrows she finds in the fire scar.
The practice is so ingrained in Martu culture that the Martu language has words for every stage of plant growth following a fire, ranging from nyurnma – a fresh fire scar – to kunarka – a landscape overgrown with spinifex.
“If you’re out hunting with Martu, it involves fire all the time,” said Douglas Bird. “You can’t understand any of their values without factoring in the fundamental role of fire.”
Comparing scars
The Martu were cleared from their lands in the mid-1960s to make way for the British government’s Blue Streak missile tests. Until the people won the official title to their territory again in 2002, an Alabama-sized portion of the Western Desert that they had previously managed saw no controlled fires.
Without human intervention, El Niño-driven monsoons had allowed dense spinifex to spring up in some areas and sprawling lightning-caused fire scars to appear in others.
“You ask the Martu people, and they explain, ‘We left, and the fire regime broke down,'” Douglas Bird said.
Now, 10 years after the Martu’s reinstatement of traditional hunting practices across their territory, the researchers compared a decade’s worth of fire scars in hunting grounds to land without an Aboriginal Australian presence.
The differences were stark. Where Martu women had hunted for goanna, the fire scars were smaller and more clustered, and there was a greater variety of ground cover.
Outside these areas, lightning strikes had burnt a small number of enormous scars, often larger than 10,000 hectares in size.
“Without the Martu, it’s very much like what we have in California,” said Rebecca Bliege Bird. “The desert is covered with a large, contiguous set of fuels.”
The burning also seemed to buffer against major seasonal changes – spreading fires throughout the year, rather than concentrating them during periods of extreme drought.
Managing for mammals
Evidence suggests that the lightning-style landscape is no good for small mammals. Thick brush is difficult to travel through – spinifex is tipped with painful silica points – and large fire scars mean few resources and more exposure to predation.
Australia’s mammal populations are disappearing faster than anywhere else in the world, and there’s reason to believe that the decline coincided with the collapse of Martu fire regimes.
“Presumably the same resources have been used for at least 5,000 years,” said Douglas Bird. “That’s plenty of time to get strong coupled interactions between humans and other mammals.”
Alternately, the researchers suggest, there is evidence that Australia’s climate variability was less extreme before humans arrived. Aboriginal peoples’ burning practices may have recreated the conditions mammals had originally evolved in.
“It challenges a bias that a lot of ecologists have,” said Rebecca Bliege Bird, “which is that all human impacts are negative.”
Western Australian Environment and Conservation officials have taken note of Martu strategies and currently conduct extensive prescribed burns across Western Australia, but official resistance to hunting and gathering remains.
“The government would rather come up with an interventionist policy than support these traditional processes that provide the same services,” Rebecca Bliege Bird said.

The world’s densest population of orangutans is set to be “extinguished” by a massive new wave of fires that is clearing large tracts of a peat swamp forest in the Indonesian island of Sumatra, conservationists have warned.
Environmentalists claim that satellite images show a huge surge in forest blazes across the Tripa peat swamp in order to create palm oil plantations, including areas that have not been permitted for clearing.
Tripa is home to a tight-knit enclave of around 200 critically endangered orangutans. However, this number has plummeted from an estimated population of 3,000.
Just 7,000 orangutans remain in Sumatra, with rampant forest clearing for palm oil cultivation blamed for their decline.
Ian Singleton, head of the Sumatran Orangutan Conservation Programme (SOCP), said that the Tripa orangutans are being “extinguished.”
“The situation is indeed extremely dire,” he said. “Every time I have visited Tripa in the last 12 months I have found several orangutans hanging on for their very survival, right at the forest edge.”
“When you see the scale and speed of the current wave of destruction and the condition of the remaining forests, there can be no doubt whatsoever that many have already died in Tripa due to the fires themselves, or due to starvation as a result of the loss of their habitat and food resources.”
Felling trees from Tripa’s carbon-rich peat also triggers the release of large amounts of CO2 into the atmosphere. Indonesia has been named as the third highest emitter of CO2 emissions in the world when deforestation is a factor, although the country disputes this.
Environmentalists have lodged a lawsuit against PT Kallista Alam, one of the five palm oil firms operating in Tripa, and Irwandi Yusuf, the former governor of Aceh, over the approval of a permit for the 1,600-hectare (3,950-acre) palm oil plantation.
Irawardi, previously styled as a “green” governor, says he granted the permit due to delays in the UN’s Redd+ (Reducing Emissions from Deforestation and Forest Degradation) programme, which has seen Norway pledge $US1bn to Indonesia to reduce deforestation.
“The international community think our forest is a free toilet for their carbon,” Irawardi said in April. “Every day they are saying they want clean air and to protect forests … but they want to inhale our clean air without paying anything.”
SOCP and lawyers representing Tripa’s local communities have called upon the Indonesian president, Susilo Bambang Yudhoyono, to bypass an ongoing government investigation into the forest clearing and immediately halt the razing of the area.
“This whole thing makes absolutely no sense at all, not environmentally, nor even economically,” said Singleton.

Fires raging unchecked in an Indonesian peat swamp forest could wipe out the remaining Sumatran orang-utans which live there, conservationists are warning. The forest is one of the last refuges of the great apes. The illegal fires, started by palm-oil companies clearing land to plant the lucrative crop, are believed to have killed at least 100 orang-utans – one-third of those living in the Tripa swamp, on the west coast of Sumatra’s Aceh province. The rest could die within weeks, according to Dr Ian Singleton, conservation director of the Sumatran Orang-utan Conservation Programme.
“The speed of destruction has gone up dramatically in the last few weeks… This is obviously a deliberate drive by these companies to clear all the remaining forests,” Dr Singleton said. “If this is not stopped right now, all those orang-utans… will be gone before the end of 2012.”
Only 6,600 Sumatran orang-utans are estimated to be left in the wild, and the Tripa swamp – where they are most densely concentrated – is considered crucial to the species’ survival. But less than one-quarter of the peat forest remains; the rest has been converted to palm-oil plantations.
Satellite imagery showing 92 fires over the past week has horrified conservationists, who are awaiting a court ruling with far-reaching implications for the protection of wildlife habitats in Indonesia. The judgment relates to a lawsuit brought against the governor of Aceh by the local branch of Walhi, an environmental group. Walhi decided to act after the governor, Irwandi Yusuf, granted a new permit to one of the country’s biggest palm-oil companies, PT Kallista Alam. Walhi Aceh argues that the permit, which would allow another 4,000 acres of peatland to be destroyed, was granted illegally.
The judges are due to reach a decision next Tuesday. If they dismiss the challenge, other important habitats could also be threatened. Tripa is nominally protected by a presidential moratorium on new logging and palm-oil concessions, as well as by legislation governing the conservation area within which it is located.
There may now be as few as 200 orang-utans left in the Tripa forest, which shelters a dozen endangered species, including the white-handed gibbon, clouded leopard, Malayan sun bear, Sumatran tiger and giant soft-shelled turtle.

In Jharia, in the federal state of Jharkhand, around 600,000 people live in the middle of one of India’s biggest coal mining areas. There’s nothing in it for most of them. Quite the opposite: the soil, the water and the air are now contaminated, of all things in an area that was previously rich in woodland.
The story of Jharia is the story of how the greed for profit, vested interests and the thirst for power have prevailed and led to one of the areas richest in minerals in India remaining so economically backward. For the mining marginalises the poor and deepens social inequality in the name of economic development, from which mostly only metropolises like Delhi, Bangalore and Mumbai profit.
Shortly after 1971, the coal mines were nationalized. Since then, their operator is the BCCL (Bharat Coking Coal Limited) which thus controls one of the biggest coal deposits in India and one of the biggest in the whole of Asia. BCCL conducts mainly opencast mining. Mostly illegally, since in 97 percent of the cases no license has been granted. Opencast mining is more profitable than deep mining. The productivity and extracted quantities are significantly higher than in deep mining and cost less. In Jharia, coal is mined in the villages, next to the houses, in short, on people’s doorsteps. Even on the streets, on railway lines, in the station itself, which is not a station any more, coal is mined.
Really, the mined area should be filled with sand and water afterwards, so it can be cultivated again. For cost reasons, however, this never happens, which leads to the coal seams coming into contact with oxygen and catching fire. India has the most coal blazes worldwide. BCCL representatives estimate there are 67 fires in Jharia alone.
The opencast mining areas are densely populated. Forty percent of Jharia’s inhabitants live in the burning, fire spewing countryside. The ground is subsiding, houses are collapsing. In addition, the smoke and vapours contain poisons, amongst others carbon monoxide, sulphur dioxide and nitrogen oxides, but also soot, methane and arsenic. The damage to health is enormous. Lung and skin diseases, cancer and stomach disorders are only some of the illnesses with which the people in Jharia have to fight with.
The blazes are in fact controllable, contrary to the BCCL representatives’ opinion. They could be extinguished with the application of water, clay and sand. But nothing happens. Because there is no political interest in extinguishing these blazes at all. Rather, it is in the operator’s interest that even more land catches fire – and thus becomes uninhabitable. BCCL needs still more land on which coal can be mined in order to achieve the extracted quantities planned for the current and coming business years. And underneath Jharia lie more than 1,000 million tons of coal.
The interests and influence of the operator are too strong, so the mines stay and the mining will still be carried on. In addition, the Mafia has the area around Jharia firmly in its hands and makes a not inconsiderable profit through blackmail, bribery and other criminal activities.
Instead of doing something against the fires, one of the biggest resettlement plans worldwide is to be carried out: Jharia Action Plan (JAP). The inhabitants of the areas on fire are supposed to be resettled in Belgaria, a new town in the middle of the jungle. There is no school there, no medical care, no shops, and, worst of all, no jobs at all. So many decide to stay in Jharia. On the fire. In spite of the blazes. In spite of the perpetual grey veil that lies over the town. In spite of the air pollution, which makes breathing almost impossible on a bad day. And in spite of the coal dust, which settles like a second skin on the body.

Rising temperatures are drying out northern forests and peatlands, producing bigger and more intense fires. And this will only get much worse as the planet heats up from the use of ever larger amounts of fossil fuels, scientists warned last week at the end of a major science meeting in Vancouver.
“In a warmer world, there will be more fire. That’s a virtual certainty,” said Mike Flannigan, a forest researcher at the University of Alberta, Canada.
“I’d say a doubling or even tripling of fire events is a conservative estimate,” Flannigan told IPS.
While Flannigan’s research reveals forest fire risk may triple in future, a similar increase in peat fires will be far more dangerous. There are millions of square kilometres of tundra and peatlands in the northern hemisphere and they hold more than enough carbon to ramp up global temperatures high enough to render most of the planet uninhabitable if they burn.
A forest fire in Indonesia that ignited peatlands in 1997 smouldered for months, releasing the equivalent of 20 to 40 percent of the worldwide fossil fuel emissions for the entire year, he said.
“There is the potential for significant releases of carbon and other greenhouse gases (from future peat fires),” Flannigan said.
If peat fires release large amounts of carbon, then temperatures will rise faster and higher, leading to further drying of forests and peat, and increasing the likelihood of fires in what is called a positive feedback, he said.
When the increased fire from global warming was first detected in 2006, Johann Goldammer of the Global Fire Monitoring Center at Germany’s Freiburg University called the northern forest a “carbon bomb”.
“It’s sitting there waiting to be ignited, and there is already ignition going on,” Goldammer said according to media reports in 2006.
Flannigan’s research is based on climate projections for 2070 to 2090. Forests will be drier and there will be more lightning with rising temperatures. Around the world, most fires are caused by humans, except in remote regions like boreal forest and treeless tundra, he said.
Lightning sparked the 1,000-square-kilometre tundra fire fuelled by peat in Alaska’s Anaktuvuk River region in 2007. Lightning, once nearly unknown in the far north, is becoming more common as the region is now two to three degrees C warmer. Until the past decade, fire had largely been absent from the tundra over the past 12,000 years.
The Anaktuvuk River peat fire burned for nearly three months, releasing about two million tonnes of CO2 before it was extinguished by snow. That’s about half of the annual emissions of a country like Nepal or Uganda. Surprisingly, the severely burned tundra continued to release CO2 in the following years.
Peat can grow several metres deep beneath the ground. In fact, some peat fires burn right through winter, beneath the snow, then pick up again in the spring, said Flannigan.
About half the world’s soil carbon is locked in northern permafrost and peatland soils, said Merritt Turetsky, an ecologist at Canada’s University of Guelph. This carbon has been accumulating for thousands of years, but fires can release much of this into the atmosphere rapidly, Turetsky said in a release.
Over the past 10 years, fires are burning far more boreal forest than ever before. Longer snow-free seasons, melting permafrost and rising temperatures are large-scale changes underway in the north, Turetsky and colleagues have found.
Other researchers have shown that the average size of forest fires in the boreal zone of western Canada has tripled since the 1980s. Much of Canada’s vast forest region is approaching a tipping point, warned researchers at the Helmholtz Centre for Environmental Research, Germany’s largest research organisation.
This “drastic change” in normal fire pattern has occurred with a only a small increase in temperatures relative to future temperatures, the German researchers concluded in a study published in the December 2011 issue of The American Naturalist.
Worldwide, fires burn an estimated 350 to 450 million ha of forest and grasslands every year. That’s an area larger than the size of India.
The first-ever assessment of forest and bush fires’ impact on human health estimated that 339,000 people die per year from respiratory and other fire-related illness.
“I was surprised the number was this high,” said Fay Johnston, co-author and researcher at University of Tasmania, Hobart, Australia.
Half of the deaths were in Africa and 100,000 in Southeast Asia. Deforestation fires in the tropics are the worst when it comes to human health impacts, she said. Heavy smoke contains high volumes of tiny particles that are very damaging to the lungs and cardiovascular system and can produce heart attacks.
“It takes humans to burn a rainforest. This would be the easiest to stop compared to other fires,” Johnston told IPS.
Forest and bush fires result in many billions of dollars in material losses every year. Last year, fires in drought-stricken Texas resulted in at least five billion dollars in losses, while the Slave Lake, Alberta fire was Canada’s second worst disaster at 750 million dollars.
Future fires will be bigger and more intense and largely beyond our abilities to control or suppress, said Flannigan.
“Virtually all of Russia, Canada, the U.S.” will be impacted, he said.
