Dominance-diversity and distribution pattern along an altitudinal gradient of Garhwal Himalaya

In this study, we examined the species composition, distribution pattern and diversity of tree andshrub species along an altitudinal gradient of Garhwal Himalaya. Vegetational analysis was analyzedalong four forest stands at an altitude of 750m-1000m a.s.l. The total tree density ranged from 340-610tree/hac. Pinus roxburghii displayed maximum density and IVI at all four sites. Carissa apaca showedmaximum density and IVI amongst shrubs. Trees were distributed randomly while shrubs displayedcontagious distribution. Species diversity ranged from 0–1.87 amongst trees while.98-1.36 values arereported for species diversity of shrubs..
