ABORIGINAL FIRE REGIMES and CONTROL BURNING

(A post from January 25th, 2018)

ABORIGINAL BURNING REGIMES

With today’s news on the ABC that the Wye River fires happened “despite years of extensive planned burns”, hopefully governments will finally understand that their fuel-reduction control burning regimes are fatally flawed and have been so from the very beginning.(1)  The inescapable conclusion after decades of expert research is that following the principals of Aboriginal fire regimes is the solution to wide scale environmental protection, restoration and ongoing management, bearing in mind that although these principals hold true, details may need a collaborative adaptation with Western experts, as what worked well for them no longer necessarily applies now that the biodiverse ecologies they once managed so effectively have been massively cleared, degraded, polluted, built-on and altered in many detrimental ways.

Indigenous forest management burning regimes, revealing a deep and profound integration with Nature and based on successfully tried & tested practices over many thousands of years and through numerous changes in climate, are receiving increasing attention. My own research reveals a pan-Aboriginal practice of never interfering in any way with any dense, closed-canopy ecologies, such as tropical and temperate rainforests, dry vine scrub, brigalow, mangroves, montane ash forests and monsoon thickets – such ecologies were left intact and protected from fire by routinely burning around the perimeters to prevent any uncontrolled wild fire from entering them.(2)

Aboriginal burning regimes were traditionally used for hunting, farming, signalling(3) and discrete ecosystem micro-management. Wide corridors and small patches were kept burnt in these forests however, for marsupial grazing, ceremonial purposes, access to sites of significance and for trade route thoroughfares, which enabled easy walking, kept snakes away and provided fresh grazing for prey animals to feed people on their long stretches of journeying. The nature of the high density biomass of these zones generated regular rain cycles which also helped keep undergrowth damp, thus inhibiting fires. Clearing and fragmentation has severely disrupted them and dried them out.

The recent fires in Esperance WA were fueled by pre-harvest standing crops and stubble, initiated by lightning strikes in extreme weather conditions. This scenario will inevitably be repeated across the continent with global warming causing more frequent and severe weather conditions and events. No amount of control burns in bushland can prevent that. In fact, the only hope there is to stop wildfires is to regenerate and restore some of those vast areas of cleared and degraded habitats back to bio-rich, naturally fire-retardant bushlands and to connect last remnants wherever possible with either wildlife corridors or stepping stone islands.(4)

We can never go back to the perfect equilibrium in which Aborigines maintained the biodiverse ecosystems of this continent, but we can learn to manage what remains of them in collaboration with the Traditional Owner Knowledge Keepers. It is appropriate that Aboriginal science, fine-tuned over many millennia, informs today’s management of these ecologies.
