Premavani D, Naidu MT, Kumar OA, Venkaiah M. 2017. Diversity and distribution of tree species in tropical forests ofNorthcentral Eastern Ghats, India. Asian J For 1: 27-32. The diversity and distribution of tree species were studied in three 1 ha sites oftropical forests in the northcentral Eastern Ghats of India. The phytosociological data from forest sites were analyzed quantitatively todetermine the basal area, species diversity, richness and stand density. A total of 1,507 individuals of 104 plant taxa, pertaining to 82genera under 41 families were enumerated at ≥15 cm gbh using belt transects (5 m × 1000 m). Tree stand density varied from 371-660individuals per ha while average basal area ranged from 14.54 – 46.51 m2 ha-1. Shannon-Weiner Index (H') ranged from 0.97-0.98,Equitability or evenness index ranged from 0.70-0.79 and Margalef richness index ranged from 10.54 – 10.82. The most dominantfamilies were Rubiaceae, Euphorbiaceae, Fabaceae, Moraceae, and Verbenaceae. Our results suggest further development of forestmanagement and biodiversity conservation in Eastern Ghats region.
