FOREST FIRES

Forest fires are an annual occurrence in Uttarakhand, and Himachal Pradesh. Over 4,500 hectares have been affected in Himachal Pradesh, some 40% more than the 3,185 hectares in Uttarakhand. The latter state has seen 1,470 incidents of fire so far — 803 (affecting 1,413.58 ha) of which were in the Garhwal region, 463 (1,076.21 ha) in Kumaon, and 204 (695.65 ha) in wildlife zones.
Nature of fire
It is very difficult to actually know how the fire started. But at least with the circumstantial evidences it is clear that there was lack of preventive measures and the preparedness was low with a weak action plan.
Forest fires as Natural Event
As a natural event Forest fire in Uttrakhand is a common phenomenon during the summer season. It is so mainly due to the presence of Chir pine trees. These trees heavily shed the highly inflammable dry Chir pine needles which acts like a fuel for combustion.
As a natural event wildfires are sometimes a natural process, and help forests by promoting flowering, branching and seedling establishment. fires that are limited to the surface may help in the natural regeneration of forests. The heating of the soil may result in helpful microbial activity, and hasten decaying processes that are useful for the vegetation.

Forest fires are a natural phenomenon and are bound to happen periodically. Some of the contributing factors are, built up of highly inflammable Chir Pine dead leaves, poor hydrological health, increasing impact of temperature increases, increasing pressure on the forests due to increasing human activity in the vicinity and repeated drought conditions.
