Bush fires blame …
Joan Lindros from the Geelong Environment Council has written an article in the Geelong Advertiser on 10 February 2010 in which she reckons that it is human activity, not excessive fuel levels in the forest, that causes bushfires. Now of course that is true … excessive fuel levels never started a fire yet!
But it misses the point!There will always be bushfires.Joan may want to ban all sorts of activities in the bush - including her favourite bashing targets of trail bikes and four wheel drives - and increase fines and jail sentences and pursuing people through the courts and cracking down with tighter controls, but we will still have bushfires. Either through human activities, or through lightning strikes. Bushfires are an inevitable part of life in Australia.
But what happened on Black Saturday in February 2009 is not necessary. It wasn’t the fact that there were bushfires that was the problem. It was the savagery of those bushfires that killed so many people. And it is possible to limit that savagery. Its simple - just reduce the amount of fuel that the fires have to burn and the fires won’t get as savage.
The way to achieve that is through control burns. Control burns reduce the fuel loads in the forest by burning dead leaves and branches and other forest detritus on the forest floor. This fuel builds up over the years, until eventually there is a huge fuel load in the forest. Enormous amounts of dry forest materials accumulate. And then if a bushfire comes through it is enormous - like a huge ongoing bonfire that goes for miles! If we then have a control burn in the forest every few years at carefully worked out intervals, we burn up all that material in what is known as a ‘cool burn’ we reduce the amount of fuel available for a bushfire to burn. Its pretty simple, and it works.
And because it works it saves lives. Saves homes. Control burns save both lives and homes.
So why doesn’t Joan want us to use control burns? Because she reckons that will reduce the bio-diversity in Victoria’s forests! That is in itself unproven. And it also raises the question - if control burns reduce biodiversity, what do bushfires do? Increase it? What is proven is that control burns reduce the intensity of bushfires, and in doing so save lives.
