FOREST FIRES – ENVIRONMENT

News: Forest fire in Kodaikanal rages for more than 20 hours

 

What's in the news?

       A major fire that broke out in a deep gorge in Perumalmalai in Kodaikanal range in Dindigul district on March 14 night was contained after a struggle of over 20 hours.

       The fire caught on dry lands with mostly rocks so no major loss occurred.

 

Causes of forest fires:

1. Natural causes:

       Lightening

       Global warming

       Increasing dry spells

       Lack of atmospheric moisture and rainfall

       Wind speed

       Friction between dry leaves

       The most vulnerable stretches of the world to forest fire are the youngest mountain ranges of the Himalayas. With large-scale expansion of chir forests in Himalayan mountains, the frequency and intensity of forest fires have increased alarmingly.

 

2. Man-made causes:

       Poachers set a small patch of forest on fire to divert the wild animals which many times leads to such fires.

       Jungle areas are also set on fire by villagers to clear the dry leaves on the ground for easy collection of mahua flowers.

       Villagers burn patches of sal trees in the belief that it will lead to better growth when planted again.

       Campfires

       Shifting Cultivation.

       It has been estimated that 90% of forest fires in India are man-made.

 

Impacts of forest fires:

       Loss of biodiversity and ecosystem.

       Air Pollution.

       Destruction of watershed.

       Forest fires can cause a lot of damage to the regeneration in the forests and their productivity.

       Moisture-loving trees such as Oaks and Deodars may give way to other species and exotic weeds.

       The burning of forest firewood causes economic losses as well.

       Forests help maintain aquifers and continuous flow of streams and springs, and provide firewood, fodder and non-timber produce to the local communities – all these capacities may get adversely affected in case of a fire.

       Forest fires may destroy organic matter in the soil and expose the top layer to erosion.

       They may also impact the wildlife by burning eggs, killing young animals and driving the adult animals away from their safe haven.

       Sometimes, a forest fire may get out of control and extend to human settlements, thus posing danger to human life and property.

 

How to prevent forest fires?

       Forecasting fire-prone days using meteorological data.

       Clearing camping sites of dried biomass.

       Early burning of dry litter on the forest floor.

       Growing strips of fire-hardy plant species within the forest.

       Creating fire lines in the forests are some of the methods to prevent fires. The fire lines are strips in the forest kept clear of vegetation to prevent the fire from spreading.

       In 1999, the state government notified forest fire rules which restrict or regulate certain activities in and around forest areas such as lighting a fire, burning agricultural stubble or undergrowth (ghasnis) and stacking inflammable forest produce such as dried leaves and firewood.
