What are the positive effects of a forest fire?
• One of the biggest positive effects of wildfire is that it helps decrease disease insects. In fact, more trees are killed every year by insects than forest fires. A low intensity forest fire actually helps the forest in its struggle against infestation, which could even cause a bigger forest fire later.
What causes forest fires naturally?
Natural Causes . Lightning is the biggest natural cause of forest fires. The different lightning strokes of varied electric voltages cause fire through directly igniting vegetation with high currents. Lightning fires are always more common immediately after dry seasons when vegetation is still dry.

What is a forest fire?
FOREST FIRES A forestfire is any uncontrolled fire in combustible vegetation that occurs in the countryside or a wilderness area. [1] [2] Other names such as brush fire, bushfire, forest fire, grass fire, hill fire, peat fire, vegetation fire, veldfire, and wildland fire may be used to describe the same phenomenon depending on the type of vegetation being burned.

What is the primary driving force of deforestation?
Speaking of the causes for this global issue, human activity is always considered as the primary driving force of deforestation, in which illegal logging is the first cause. Illegal logging stands for the action of harvesting, processing, transporting and buying or selling timber and wood products without the permission of law and regulation. Nowadays, people are not hesitating to cut down tons of trees and forest to earn more profits, but not being aware of deforestation. In the article “Deforestation

INTRODUCTION Forest fire can lead to heavy loss of natural reserves in National Park. It may be accidental due to chemical present in soil, air and temperature in dry vegetation. Forest fires may also cause a long term effect on the forest soil.
How do wildfires affect the biosphere?
Wildfires can destroy entire habitats of plants and wipe out life over miles of land. Once these fires clear large areas of vegetation the loss of plants can heighten the risk of significant erosion and landslides. In sudden rainfall these cleared areas become extremely dangerous and some observers have even reported soil “glassification,” where the silica in the soils become melted and fused, forming an impermeable layer in the soil. This impermeable layer can make it very difficult for future plants to grow back and for animals to re-inhabit the area. Although many don’t think of a benefit to wildfires in the biosphere, there are some positive outcomes of wildfires.
How does deforestation affect agriculture?
Moreover, deforestation makes the soil weak creating erosion and in the long run, it could affect the agriculture. In addition, when deforestation becomes a situation of consideration, others systems do so. For instance, the water cycle can be affected since trees are responsible of evaporating the water, which then is condensed and then reaches again the trees to complete the cycle. Nonetheless, as many trees have been burned to make different uses of the land, the water cycle cannot be as efficient as it used to be. Therefore, different parts of the world can be affected by deforestation of the Amazon forest.
How does fire affect biodiversity?
The frequent occurrence of forest fires has been one of the vital reasons for the exhaustion and extinction of most of the biodiversity. This results in partial or complete degradation of vegetation cover or fragmentation of the forest thus modifying the radiation balance by growing the surface albedo, water runoff and raising the soil erosion (Darmawan and Mulyanto, 2001). Historical study of forest fire is significant for ecological and forest management applications (Iniguez et al. 2008).
What happens when a forest fire burns?
Large scale fires result in a loss of topsoil. The hot temperatures reached in large fires burns away the topsoil and organic material in the soil that is vital to the health of the forest. Less vegetation as a result of forest fires doubles the amount of runoff flowing into mountain streams, and increases the speed at which snow melts ...
How does fire affect soil?
Fire having low intensity helps in increasing the soil nutrients by burning out the litters and soil’s organic matters . On the other hand fire having high intensity can damage the soil’s organic matter, kill micro organisms and volatize chemicals which are the important elements for the tree’s growth .
What causes fires in the forest?

How does fire spread?
Normally fire spreads along the ground in horizontal plane but presence of dry climbers on trees, resin channels in chir forests or lichens in deodar forest, induce it to spread at planes at right angles to the normal plane i.e. along the crowns of trees.
Why can't we use water in forests?
By Water: This method cannot be applied on a large scale in our forests because of dearth of water. Water is, however, used, after the fire has been controlled, in extinguishing burning stumps near the line of control as sparks from such stumps, which may keep smoldering for weeks, can start fresh fires. ii.
