Aboveground biomass and net primary production of semi-evergreen tropical forest of Manipur, north-eastern India

Abstract

The aboveground biomass dynamics and net primary productivity were investigated to assess the productive potential of Dipterocarpus forest in Manipur, Northeast India. Two forest stands (stand I and II) were earmarked randomly in the study site for the evaluation of biomass in the different girth classes of tree species by harvest method. The total biomass was 22.50 t·ha⁻¹ and 18.27 t·ha⁻¹ in forest stand I and II respectively. Annual aboveground net primary production varied from 8.86 to 10.43 t·ha⁻¹ respectively in two forest stands (stand I and II). In the present study, the values of production efficiency and the biomass accumulation ratio indicate that the forest is at succession stage with high productive potential.
