MOHAMMAD WAHAB, MOINUDDIN AHMED AND NASRULLAH KHAN

Abstract: Phytosociological sampling, structure, age and growth rates studies were carried out in 5 places of Dangam District of Afghanistan. Vegetation compositions of non tree species were also presented. On the basis of floristic composition and importance value index of tree species, two monospecific and one bispecific communities were recognized in the study area. It is shown that in Picea smithiana (Wall.) Boiss., Dbh, age and growth rates are not significantly correlated. Lack of tree seedlings indicate poor regeneration status of the forests.
