1 Wildfires can be caused by an accumulation of dead matter (leaves, twigs, and trees) that can create enough heat in some instances to spontaneously combust and ignite the surrounding area.  Lightning strikes the earth over 100,000 times a day. 10 to 20% of these lightning strikes can cause fire.
The causes of ignition can be split into two groups, 'natural' and 'human influence'. Lightning strikes are the main way bushfires are started naturally. There are, on average, more bushfires initiated due to lightning strikes than any other individual cause, accounting for approximately 26 percent of all bushfires.The vast majority of bushfires, however, are generated by the actions or influences of humans.evere bushfires may burn all the vegetation in a particular area, while more moderate fires will, generally, cause less damage to the natural surroundings. The most obvious result of fire is the loss of plant and animal life. When an area is burned out, vegetation is destroyed as it was used by the fire as fuel.
