Introduction
Natural vegetation refers to plant communities that have grown naturally without human intervention and have remained undisturbed for extended periods.
In India, various types of vegetation are identified, including:
- Tropical Evergreen Forests
- Tropical Deciduous Forests
- Tropical Thorn Forests and Scrubs
- Montane Forests
- Mangrove Forests
Body
Types of Forest Fires:
- Ground Fires: Burn organic material in the soil slowly, under the vegetation.
- Surface Fires: Result from the burning of dry leaves, branches, and other ground materials. These spread swiftly, as seen in Himachal Pradesh.
- Crown Fires: Burn from one tree top to another with intense heat and large flames. These are rare in India.
Increasing Intensity of Forest Fires:
- The number of forest fire points increased from 8,735 to 42,486 over four weeks in March last year.
- Forest fires have significantly impacted green cover in Uttarakhand and Himachal Pradesh.
Causes of Forest Fires
Forest Fire Season:
- Lasts from November to June in India.
- Key factors influencing forest fires include temperatures, precipitation, vegetation, and moisture levels.
High Fire Incidence:
- According to the Forest Survey of India, nearly 36% of India’s forests are prone to frequent fires.
- Higher incidents are reported in March, April, and May due to the availability of dry biomass (fuel load) after winter and during summer.
Human Factors:
- Most forest fires are man-made, stemming from agricultural practices and unchecked land-use changes.
Conclusion
Forest fires in India are a growing concern, particularly in hilly regions, due to a combination of natural and human factors.
Effective management and preventive measures are crucial to protect India’s diverse vegetation and mitigate the adverse impacts of forest fires.
