Tree ring width chronology of Blue pine (Pinus wallichiana) from dry temperate forest of Bomborat, Chitral Forest Division was developed to identify the effect of climate change happened in this area for the last 30 years. The climatic parameters including mean monthly temperature and precipitation were taken into consideration for the determination of impact over time scale (1985-2015). Results showed an obvious transformation in both correlation and response coefficients of this tree species during the months of August and September of the previous growth year to current growth year because of monthly mean temperature and precipitation. Temperatures during the spring season coupled with the availability of water from precipitation found important for the growth of these trees and this relationship may be used to reconstruct the temperature from the developed chronology for Chitral area.
