Except for periods of precipitation in monsoon and winter, the forests remain vulnerable to wildfires. Forest fires are a recurrent annual phenomenon in the state, and most commonly occur in Chir Pine forests.
In the summer season, forest fires occur frequently in the low and middle hills of the state, where forests of Chir Pine are common.
During the post-monsoon season and in winters, forest fires are also reported in higher areas, including parts of Shimla, Kullu, Chamba, Kangra and Mandi districts, where they usually occur in grasslands.
