What Causes a Forest Wildfire?
Forest fires can erupt due to natural causes like friction due to the rubbing of trees or lightning that further causes combustion of debris. It can also happen due to human actions like smoking and cooking the forest. A larger percentage of forest fires happen due to human neglect
Forest fires are based upon something known as the fire triangle. A forest fire needs heat, oxygen, and fuel to spread. Destroying the supply of any one of these elements will help extinguish the forest fire.
Forest fires can be classified into three main categories based the part of the forest in which they occur.
- Ground fires occur at the ground level, beneath the branches
- Surface fires can be about 1.3 meters high
- Crown fires generally spread through treetops. These are very dangerous. They might be fuelled by surface fire.
Controlling the Wildfire
- Ground fires are usually controlled by digging trenches
- Surface fires can be effectively managed via firebreaks
- A crown fire is probably the hardest to extinguish. You might need fire retardant chemicals as well as the help of professional firefighters.
For convenience, fire safety while hiking can be divided into four main phases.
