Abstract

Phyto-sociological study was carried out in eight villages of Chamoli district of Garhwal Himalayas at the elevation of 1000–3000 m asl with northern and southern aspects. The IVI was recorded maximum in tree species in F₁-forest in Boehmeria rugulosa, in F₂-forest in Bombax ceiba, in F₃-forest in Cedrus deodara, in F₄-forest in Lyonia ovalifolia, in F₅-forest in Machilus odoratissima, in F₆-forest in Ficus palmata, in F₇-forest in Quercus leucotrichophora and in F₈-forest in Acer oblongum. The value of index of dominance (Simpson index) in tree species was higher in forest-F₅ (0.794). The value of Species Diversity in tree species was highest in Forest-F₅ (1.622). The value of tree species equitability was higher in forest-F₅ (0.124). Tree species richness was recorded maximum in forest-F₂ (0.109) and beta diversity was recorded maximum in forest-F₇ (10.300).
