Phytosociological assessment & distribution patterns of tree species in the forests of Doon Valley, Shivalik hills of lower Himalaya
Mohommad Shahid* and Shambhu Prasad Joshi
Abstract:
Study was conducted in the three forest ranges (Barkot, Lachchiwala and Thano) of Dehra Dun forest division, Doon Valley, Uttarakhand, India. Phytosociological studies of the sites were conducted for tree species. Fifty quadrats of 10 × 10 m2 size were laid on each site for studying the trees composition and structure. Diversity Indices were calculated for each site. Species richness ranged between six species in Thano to 15 species in Barkot. Two Way Indicator Species Analysis was performed and classified tree layer into eight groups depending on the eigen value.
