Estimation of carbon storage for Pistachio atlantica Desf. (Case study: Firuzabad Pistachio and Amygdalus forest research, Fars province)

This research investigates the carbon sequestration potential for Pistachio atlantica Desf in Firuzabad Pistacia and amygdalus forest research in Fars province. Using Random-systematic inventory for determining the number of trees in 5-cm diameter classes, 3 trees were selected in each diameter class, they were cut and trunk, branches, leaves and litter were weighted separately. Samples were transferred to laboratory. Organic carbon and its conversion ratio were measured. In order to estimate the organic carbon storage in soil, samples were randomly taken in aspects and flat terrains. Their contents were compared with control samples. The results showed that carbon sequestration potential for Pistasia atlantica Desf is 1.99 tons per hectare and 18654.3 tons in total. Soil carbon storage is 12.78 tons per hectare. Duncan test showed that there is a significant difference among the tree components (p<0.01). The highest and lowest Sequestration belongs to the trunk and leaves, respectively. Leaves and litters have the lowest and highest conversion ratio organic carbon, respectively. These results show that by increasing the density and conserving these forests, much carbon Sequestration can be done by Pistasia atlantica Desf due to their vast distribution.
