Abstract
Dendrochronological studies were conducted based on the data of 41 different mature stands of moist temperate areas of southern Himalayan and Hindukush region of Pakistan. Wood samples as cores were obtained from 222 trees including those of Pinus wallichiana A.B. Jackson, Abies pindrow Royle, Cedrus deodara (Roxb.) G. Don., Picea smithiana (Wall.) Boiss., and Taxus fuana Nan Li & R.R. Mill., using an increment borer. Age and growth rates of these trees were estimated. Correlations were sought between the diameter / age, diameter / growth rate and age and growth rate on the basis individual stands and on an overall basis. More than 50% correlations were found to be significant. Relationship between the growth rate of dominant conifer species with environmental factors (soil nutrients, edaphic factors and topographic factors) was also sought. In general, they disclosed poor relationships. Growth rate of Abies pindrow showed weak correlation (p
