Pattern of distribution of species abundances in ‘Khasi hill sal’ forest of Meghalaya in a rank-abundance plot based on ln-transformed importance value index (IVI) of species. A fit of unweighted simple least square was significant (solid line, y = –0.037x + 1.924, n = 123, R² = 0.912). On exclusion of top four species, the fit was marginally better (dashed line, y = –0.034x + 1.688, n = 119, R² = 0.954). The top five species in descending order of IVI are: S. robusta, S. wallichii, P. kesiya, C. arborea and Callicarpa arborea.
