Vegetational structure and plant diversity relation in a sub-alpine region of Garhwal Himalaya, Uttarakhnad India

The present study investigated the community structure of a sub-alpine region of Mandal Valley (2200 to 3000 m) along the altitudinal gradient in Garhwal Himalay abased on analytic and synthetic characters. Poa annua was dominant and Potentilla fulgence was co-dominant along the altitudinal gradient, indicating that most of plant species in different communities were contagiously distributed. Species niche width indicated wide distribution of the species along all altitudinal gradients.
