Tree-ring width index chronologies of some species (Abies pindrow and Picea smithiana) of Western Hima-laya are sensitive to the moisture availability and amount of soil moisture of the region. The first prin-cipal component among the site chronologies explain-ing 61.2 of the common variance is strongly correlated with Palmer Drought Severity Index dur-ing summer season (May-July). Whereas increased temperature of the region had significant adverse effect on tree growth. The moisture availability, espe-cially in the growing season is found more conducive in developing the annual tree-ring width compared to rainfall during the season. Moreover, the increasing temperature and vapour pressure during November and December of the previous year might play an important role for early snow melt over region, which maintains enough soil moisture favouring trees growth during subsequent growing season of the trees as well as in physiological processes.
