The present study was undertaken in five major forest types (dominated by Quercus semecarpifolia, Quercusfloribunda, Acer acuminatum, Abiespindrow and Aesculus indica, respectively) between 2400 and 2850 m a.s.1, in a moist temperate forest of the Mandal-Chopta area in the Garhwal region of Uttarakhand, India. The aim was to assess the variation in composition and diversity in different vegetation layers, i.e., herb, shrub and tree, among these five forest types. Diversity indices, such as the Shannon-Wiener diversity index, density, total basal cover, Simpson's concentration of dominance index, Simpson's diversity index, Pielou's equitability, species richness, species heterogeneity and r-diversity, were calculated to understand community structures. Dominance-diversity curves were drawn to ascertain resource apportionment among various species in different forest types. 展开更多
