Ring-width chronology of 211 years (AD 1730-2010) was developed using Himalayan Pine (Pinus wallichiana) collected from Ganji Skardu mono-specific Pinus wallichiana forest near the mix forest of Pinus wallichiana, Juniperus excelsa and Betula utilis on different aspect and slope angle. Chronology statistics showed that Pinus wallichiana have the past climate signal. Strong correlation has been observed between tree growth and previous November temperature indicating that winter warmth is the main factor responsible for tree growth. Correlation analysis between tree ring chronology and grid data also indicates that summer temperature and precipitation is useful for tree growth. More sample collection would prove better results.
