Did fire-stick farming cause the extinction of Australian megafauna?

Fire-stick farming had the long-term effect of turning dry forest into savannah, increasing the population of nonspecific grass-eating species like the kangaroo. One theory of the extinction of Australian megafauna implicates the ecological disturbance caused by fire-stick farming.

What is’firestick farming’?

The overall result of Aboriginal use of fire – what has been termed firestick farming – was a regular, light, mosaic pattern of burning that created a varied array of neighbouring habitats at different stages of regeneration after fire.

Is it possible to invest in cultural fire stick farming?

Australia’s Black Summer—our devastating 2019-20 bushfire season—highlighted the symptoms of climate change and led to strong interest in Aboriginal cultural fire stick farming practices. Fortunately, it’s now possible to invest in fire stick farming, also known as cultural burning, by purchasing carbon offsets.

Why is savanna burning good for biodiversity?

Carbon credits produced on Aboriginal lands using the savanna burning methodology is good for biodiversity and jobs for Aboriginal rangers.

What is the Aboriginal Carbon Foundation?

After some research and discussions, we chose to partner with the Aboriginal Carbon Foundation, an Indigenous not-for-profit that supports carbon projects and maintains an office in Sydney.

What is fire stick farming?

What fire stick farming involves. Fire stick farming is a way of managing the environment Aboriginal communities have practiced for tens of thousands of years. It improves the health of the land and wildlife by setting cool burns, generally spot fires with smaller, more controlled flames during the early, cool dry season.

Why is cultural burning important?

Larger, hotter, fires emit more carbon emissions than cool burns. So cultural burning reduces carbon emissions—the release of strong greenhouse gases into our atmosphere. zoom_in.

Why do people use fire sticks?

Reducing vegetation that’s likely to fuel uncontrollable fires is only one aim. Fire stick farming also supresses weeds and improves conditions for native wildlife, plants and grasses. It’s also used to create or clear pathways to gain better access to Country for cultural purposes. Trained Elders carry out the cool burns.

Where is the Tiwi Islands?

The Tiwi Islands are part of the NT, 80km to the north of Darwin adjoining the Timor Sea.

Where do fire sticks grow?

Currently, most fire stick farming occurs in the NT, northern QLD and northern WA. In 2018, for example, there were nearly 80 cultural burns across savannas in northern Australia.

Why are fire sticks important to Aboriginal people?

Fire sticks (firebrands) were part of the spiritual tool kit used during special fire ceremonies and rituals and to cleanse vegetation of evil spirits serving the dual purpose of making the land both productive and spiritually safe.

What are the views on pre-European Aboriginal fire management and its effects on the landscape?

Any views on pre-European Aboriginal fire management and its effects on the landscape are important for the politically-charged arena of modern fire-management regimes in particular the assumption that Aboriginal-like fire management, especially the use of low intensity fires, could prevent modern extreme bushfires.

What was the highest environmental impact technology used by Aboriginals as a highly effective land management and hunting tool?

Fire was the highest environmental impact technology used by Aboriginals as a highly effective land management and hunting tool. Burning the land was regarded as a ‘cleaning’ process, removing dead wood, dense brush and thorny shrubs, clearing tracks, renewing the vegetation and preventing devastating high-intensity fires. Fire-stick Farming.

How often do fires happen in Australia?

Different fire practices around the country are discussed by Gammage who states that ‘ Most Australia was burnt about every 1-5 years depending on local conditions and purposes …’ [3] Without regular low-intensity burns land soon reverted to scrub. Fire produced land that was reborn and accessible, it was deliberately used to make grass. Burns were generally lit in summer and timed to die out by nightfall. In the Centre they were timed before rain which could be forecast from the behaviour of particular animals and here burning to flush out game was not common, hunting during fires generally being a secondary concern. Plants were also burned selectively.

Why was smoke used in the caves?

Smoke was used to drive animals from their burrows, bats from their caves, and to deter troublesome insects, especially mosquitoes, from campsites and when fishing as it gave light and warmth. Different woods and plant parts were selected according to use – for th eproduction of light, steam, smoke, heat or duration.

How was fire created?

Fire was created anew in several ways: by fire-saws (thin wooden slats rubbed rapidly backwards and forwards in a wood groove filled with combustible tinder, sand sometimes being added for additional friction); fire drills (various kinds of thin wooden cylinders rolled between the hands with the point spinning and concentrating the energy into a small wooden slot with paperbark as kindling); or sometimes by striking rock like flint against ironstone to ignite kindling which included dry kangaro o dung, grass, feathers, bark etc. To avoid the effort of constantly re-making fires smouldering firebrands were maintained for long periods, sometimes as embers or long-burning materials like banksia cones, bracket fungus, rotten wood, or rolled bark.

What is ash used for?

There were many other uses: for cremation, cooking, manipulating resins, and hardening wood, especially when fashioning axes and spears. Ash was rubbed into open cut skin to produce decorative body scarring.

Why are there patches of eucalypts in the Cape York rainforest?

N.B. Tindale accounts for the presence of patches of eucalypt and open plains in the Cape York rainforest as, again, being due to Aboriginal firing.

What does the broken line represent?

The broken line represents the 100-fathom line which would have been the approximate coastline more than 10 000 years ago . (Map by the author.)

What is the savannah woodland?

The savannah woodland, merging into open plains, characteristic of central and western New South Wales, is similar in many ways to that of eastern Tasmania and, again, has been heavily modified by Aboriginal burning. In 1848 Major Thomas Mitchell, the explorer, said with brilliant insight of these park woodlands:

What factors are involved in the distribution of Notofagus?

Many factors are involved in the distribution, such as soil type and aspect and climatic change , but a long history of firing has reduced the Notofagus -dominated rainforest in many places through a mixed eucalypt-rainforest phase to scrub and, eventually, to sedgeland and heath.

Why do people throw lighted matches in the bush?

The answers have ranged from “it’s fun” to “it’s custom.”

How long has the white man been on the continent?

The white man has been on this continent for 200 years in some places and less so in most others. Before he arrived, the continent had been colonized, exploited, and moulded by other men—the Australian Aborigines and their ancestors for tens of thousands of years [Figure 1 ].

Why do kangaroos burn grass?

Fire, grass, kangaroos, and human inhabitants seem all dependant on each other for existence in Australia… Fire is necessary to burn the grass and form those open forests, in which we find the large forest kangaroo; the native applies that fire to the grass at certain seasons, in order that a young green crop may subsequently spring up and so attract and enable him to kill or take the kangaroo with nets. In summer, the burning of the long grass also discloses vermin, birds’ nests, etc., on which the females and the children who chiefly burn the grass, feed. But for this simple process, the Australian woods had probably contained as thick a jungle as those of New Zealand or America instead of open forests.

What is it called when you use fire sticks to farm?

It is called firestick farming by the methods of which are used to "farm" or manage the land. The people that farm this way use sticks that are lit with fire, hence the term "firestick", to make a controlled burn that will clear forested land. They are "farming" or managing the land with firesticks.

How big is a Driptodon Optatum?

a quote from wikipedia about the Driptodon Optatum: "The largest specimens were hippopotamus-sized: about 3 metres (9.8 ft) from nose to tail, standing 2 metres (6.6 ft) tall at the shoulder and weighing up to 2,786 kilograms (6,140 lb).". ya, there HUGE.

What to do if playback doesn’t begin?

If playback doesn’t begin shortly, try restarting your device.

Why is the Earth not in history?

Because Earth is in the Universe, and the study of the Universe is Cosmology. This doesn’t really belong in history because it is before written history.

Is terraforming science fiction?

More or less yes, but in all sense of terraforming you see that to be more science-fiction to large scales,This could really just be considered adapting the enviroment to us.

Did the British bring sheep to Australia?

Yes. British colonists were the first inhabitants of Australia to bring sheep with them.

What is the significance of Aboriginal land management?

Underpinning Aboriginal land management practices is a deep spiritual connection with the land that is closer to kinship than ownership, Pascoe writes . “Aboriginal people are born of the earth, and individuals within the clan had responsibilities for particular streams, grasslands, trees, crops, animals, and even seasons.”

What did early European settlers observe?

As Bruce Pascoe recounts in his influential 2014 book Dark Emu, early European settlers observed that the abundant grasslands they saw recalled the manicured parks of England. Others related seeing sophisticated fish traps and evidence of grain farming. At the height of its productivity, Australia supported large populations, writes Pascoe, thanks to the inhabitants’ “industry and ingenuity applied to food production over millennia.”

What did the Europeans do to Australia’s soil?

The hard-hooved sheep and cattle favoured by the Europeans degraded Australia’s fragile ancient soils, as did the introduction of rabbits in 1859. Productivity quickly declined as “sheep ate out the croplands and compacted the light soils,” Pascoe writes. “The fertility encouraged by careful husbandry of the soil was destroyed in just a few seasons.”

What is traditional burning?

One of the central pillars of Aboriginal land management, traditional burning was practised for millennia among Aboriginal people. It was a complex, interconnected system that spread across the continent, creating “a single estate, albeit with many managers,” writes historian Bill Gammage, author of The Biggest Estate on Earth (2011).

Why did Aboriginal people burn vegetation?

Aboriginal people systematically burnt vegetation to reduce fuel and encourage new growth to lure grazing animals for hunting.

What allowed understorey vegetation to grow unchecked?

They quickly prohibited the practice of traditional burning, which allowed ‘understorey’ vegetation to grow unchecked. Recent years has seen a renewed appreciation for practices such as fire-stick farming.

Where do Aboriginal people walk?

In central Australia, a group of Aboriginal people walk through grasslands backed by rocky outcrops with firesticks in hand, setting alight the vegetation before them.

What is the Aboriginal use of fire?

The overall result of Aboriginal use of fire – what has been termed "firestick farming" – was a "regular, light, mosaic pattern of burning" that created a varied array of neighbouring habitats at different stages of regeneration after fire. This acted to conserve plant-eating marsupials, providing good grazing and a refuge from fire in more recently burned areas, and shelter in unburnt areas. Significantly, this mosaic pattern, by creating belts of firebreaks and of areas low in fuel density, lessened the occurrence of disastrous wildfires of the type Australia so often has had to contend with in the last century.*

How did burning affect the colonial era?

Regular burning by Aborigines also had long-term effects in altering habitats and the species composition of regional ecosystems . Grasslands, open woodlands and heaths encountered by early colonial explorers were largely the results of Aboriginal burning practices – so much so that many of these more open areas began to disappear following the destruction or displacement of the traditional Aboriginal communities that maintained them.*

How did the plant communities and ecosystems encountered by the European invaders have been modified by Aborigines?

Thus the plant communities and ecosystems encountered by the European invaders had been very much modified by Aborigines through their burning practices over many thousands of years. The result is that a whole range of Australian ecosystems are dependent on, or at least tolerant of, some degree of burning.

What is the purpose of pushing an oversimplified view of the issues?

Those trying to score cheap points by pushing an oversimplified view of the issues are in fact placing obstacles in the way of the development of an effective fire risk minimisation strategy.

Why did they burn vegetation?

They also burned vegetation in order to initiate fresh growth of grasses, which served to attract browsing animals to the area , thereby improving their hunting prospects. In some areas burning was used to encourage the growth of important edible plants. Fires were also lit simply to clear the way for easier travel.

What is the only adequate response to the danger of fire in Australia?

Rather the only adequate response to the danger of fire in Australia is the implementation of a plan of action that takes real account of the complexity of the situation. Clearly, this implies the allocation of adequate resources to implement such policies over the long term, and not just when the horror of wildfires is fresh in people’s minds.

When can democratic decisions be made about burning regimes?

It is not until the community as a whole is clear about these priorities, and their implications for fire management, that democratic decisions can be made about burning regimes.

Why did people burn their land?

An example of this was fire stick farming: The low-intensity burning of undergrowth in wooded areas that would promote the germination of new plants, and thus attract the animals that were an important part of an Aborigine’s diet. This burning was carried out before the dry season and was done carefully and systematically. No more was burned than necessary. Burning was also more than just sound land management; it was evidence that the land was healthy and being fully utilised. There was also a religious significance to burning: As the Ancestral spirits of the Dreaming still inhabited the land, the burnings provided these spiritual inhabitants with lands on which they could hunt. But fire-stick farming had another purpose: to decrease the risk of the wild fires now all too common in modern Australia.

Did Aboriginal people take anything from nature?

With this attitude (belief) is it any surprise that the Aboriginal people never took anything from nature? Aborigines were the original conservationists and their use of land management promoted ecological health.

Who wrote the book Aboriginal Environmental Impacts?

In his book Aboriginal Environmental Impacts, James Kohen explains the demise of the latter:
