There are certain type of tree that have seeds with shells so think that they have to be burned off to grow.
And good mulch for the rest of the plants.

It is true, that in some parts of the world, the destruction of large forest areas by fire, is not only a natural process, but is necessary for the health and continuing life of the forest itself.
In this type of forest, the seeds of the trees either
a) can not spread, and/or b) can not germinate, unless
a) the seed pods, or seed cones, are opened by the heat of a forest fire, allowing the seeds to be propelled, or fall freely, away from the parent tree, and/or
b) the forest floor has been cleared and fertilised with ash by the fire, assisting tree seeds to germinate and grow quickly, without competition from other plants, and with reduced risk of browsing animals feeding on and destroying the young and vulnerable saplings.
In all cases of natural forest fires the initial ignition is done either by summer lightning, or the lightning which may accompany volcanic eruptions, or by the hot products, (gas and/or lava) of the eruption itself.
Unfortunately, most forest fires in the world today are not natural but are started deliberately or accidentally by human beings.

Do you mean why do forest fires naturally occur?
The natural forest fires usually happen during the hot and dry season. The plants emit flammable gases which make them suceptible to fires. Sometimes even a drop of water can act as an agent in starting a fire (think magnifying glass+Sun=fire) When this type of fire occurs the forest is not really destroyed. It can regenerate itself. The ash is rich in nutrients. When the fire is gone the soil ready for new growth.

Lightening provides the spark, forests provide the tinder.
Forest fires are not entirely destructive. They serve a number of useful purposes. They help clean up dead vegetation, provide nutrients into the soil, and usually result in new growth feeding on the residue left from the old.
Forest fires do result in soil erosion which can be harmful, but generally natural forest fires do at least as much good as harm.
Without the beneficial effects of harvesting by the lumber industry about the only way nature can clean up and renew forests is through forest fires. The majority of them are not caused by man, but are the result of lightening strikes, which are abundant in many areas of the wilderness.

Natural forest fires are actually a part of the normal cycle of the forest. It enriches the soil and promotes new growth and actually helps the forest in the long run.

in summers forests grass becomes dry and it could be due to some ones smoking or due to global warming that results in fire basically it is due to human error and rarely by any natural calamity.
