FOREST
FIRE
Forest fire means a fire burning uncontrolled on
lands covered by wholly or in part of timber, brush, grass, or other flammable
vegetation. It is the most common hazard in forests. Forest fire causes
imbalances in nature and endangers biodiversity by reducing faunal and floral
wealth.
The naturally caused forest fire are usually started
by dry lightning where to no rain accompanies a stormy weather disturbance. High
atmospheric temperatures and dryness offer favorable circumstance for a fire to
start.
Still, human fire activity is the primary cause of
forest fire. Most of these human fire result from accidental causes. Accidental
fire are usually caused by carelessness or inattention by campers, hikers, or
by debris and garbage burners. Some are intentionally set by arsonist.
There are two types of forest fire. The first is surface
fire. Surface fire is a forest fire that burns only the surface litter. Surface
fires spread with a flaming front and burn leaf litter, fallen branches and
other fuels located at ground level.
The other type of forest fire is a crown fire in
which the crown of trees and shrubs burn, often sustained by a surface fire.
Crown fires—which burn through the top layer of foliage on a tree, known as the
canopy. Crown fires, the most intense type of fire and often the most difficult
to contain, need strong winds, steep slopes and a heavy fuel load to continue
burning.
The effect of forest fire are loss of valuable
timber resource, loss of biodiversity and extinction of plants and animals,
loss of wildlife habitat and depletion of wildlife, and global warming.
Forest fire can be very dangerous disaster that influence
not only the forest live, but also the area around the forest. Like Indonesian forest
disaster several times ago. So, safe our forest like safe our lungs.
