Detailed explanation-1: -Prescribed fire characteristics can be defined as the effects of flaming that cause a degree of impact on the plant communities. Fire characteristics include flame height, fire intensity, season, frequency, flame angle, flame depth and scorch height.
Detailed explanation-2: -Controlled burning, also known as prescribed burning, involves setting planned fires to maintain the health of a forest. These burns are scheduled for a time when the fire will not pose a threat to the public or to fire managers.
Detailed explanation-3: -A backburn is a fire lit close to the edge of an active bushfire, which burns out the fuel between the bushfire and an established control line. The removal of fuel halts the fire’s spread, providing suitable conditions for firefighters to finish suppressing the fire.
