Abstract :

Above ground biomass of the woody species is often considered to be one of the largest carbon pools. Hence, present study was carried out with aims to analyze the terrestrial AGB and BGB carbon and species composition in the plantation forests of Gmelina arborea and Tectona grandis of Papum Pare district of Arunachal Pradesh. Non-destructive sampling approach was adopted in the study. Species specific volume equation was used to estimate the biomass accumulation. Stand density of Tectona grandis was 813 stems/ha whereas it was 390 stems/ha for G. arborea. The basal area of T. grandis and G. arborea was 69.40 m2 ha-1 and 48.79 m2 ha-1, respectively. The above ground biomass was estimated 269.65 t/ha for former stand and 206.03 t ha-1 for later stands. Below ground biomass was recorded 78.19 t/ha in the teak and 59.74 t ha-1 in the G.arborea plantation. The total above ground biomass carbon was 902.65 t/ha, below ground biomass was 261.74 t/ha and the total soil organic carbon was 246.20 t/ha. The total carbon calculated for the plantation forests including the SOC was 886.6 t/ha. The results showed a positive correlation (R2=0.99) between the basal area and tree biomass of both the woody species. The present findings showed that T. grandis and G. arborea has significant carbon storage potential.
