Backburning in controlling bushfires to prevent spreading. by Richard Conan-Davies 19 April 2005 Backburning Back burning is basically a way of reducing the amount of flammable material during a bushfire by starting a small fire in front of a main fire front.  It is called back burning because the small fires are bdesigned to 'burn back towards the fire front'. Why and how it works The basic reason for back burning is so that there is less material that can burn when the dry hot summer comes around. Interestingly the carbon on trees( the black part) are actually quite fire resistant. By considering factors like the wind it is possible to stop a major fire front by burning sections ahead of the fire that might be more in the line of property or housing. It is also important to consider factors like geography (how hilly the area is for example). It can only be performed by firefighters with lots of planning. Hazard reduction burning This is something that usually takes place outside of the fire season often during winter.
