       Vegetation

       The Australian bush varies greatly around the country. There are regions of open woodlands, grassland savannas, dense
       rainforest. Different types of vegetation burn differently. Generally, fuel is classified as being fine (grasses and twigs that are
       less than 6 millimetres in diameter) or heavy (branches, logs or stumps). Finer fuels burn more easily, increasing the spread of
       the fire. Another key factor is fuel moisture content, or how dry the fuel is. The drier the fuel, the more easily it will burn. The
       dryness of the fuel depends on seasonal rainfall and temperatures.



       Topography

       Fires burn faster uphill. This is due to the radiation and convection a fire creates preheating the fuel. A 10-degree increase in
       slope results in a doubling of the speed of the fire. Fire will spread up a 10-degree slope two times as fast as it will along flat
       ground (Figure 6). The aspect of a slope (direction that a sloping piece of land is facing) influences a fire's behaviour. Northern
       and western aspects receive more direct heat from the sun, drying both the soil and the vegetation more than on southern or
       eastern slopes. The fuels on northern and western aspects are often drier and less dense than fuels on slopes with a different
       aspect.
