Chir pine is a coniferous tree species that is native to the Himalayan region. It is found in Himachal Pradesh, J&K, Uttarakhand, Sikkim and Arunachal Pradesh. Forests bearing chir pines are prone to forest fires. This is because they shed their needles (modified leaves) during the dry summer season. This creates conditions favourable for wide spread of fires, especially with the help of winds. These trees are relatively immune to the damages from the fire. Recently, the Kullu fire raged for days before being brought under control.
