Abstract

Present study was conducted in the dry Sal forest at Pandowala, situated in Ramgarh Forest Range of Rajaji National Park. The results of the study reveal that (1) demographic dispersal of species has not changed much in all the three layers viz. tree, shrub and herb, (2) Sal forest at Phandowala is experiencing significant changes in the species richness, species diversity and concentration of dominance and (3) the conversion rate of Sal seedlings to saplings is nil, which means no regeneration of Sal.
