Eucalyptus species are the dominant plantation species and have greater economic and environmental value in Ethiopia. Little is known on the carbon stock of Eucalyptus species and hence this study aimed to estimate the carbon stock of Eucalyptus grandis and Eucalyptus camaldulensis stands in Kibrit plantation forest. Systematic random sampling was used and a total of 60 plots (10m*20m) were systematically established. Trees ≥ 5cm diameter at breast height and height were measured. Within each sample plot, (1m*1m) subplots were designed for litter and soil sample collection. Species specific allometric equations were used to estimate the tree biomass. Soil organic carbon determination was done using the Walkley Black method. The mean total carbon stock (biomass plus soil organic carbon) was significantly higher (p< 0.05) in Eucalyptus grandis (351.72±72.72 t/ha) than in adjacent Eucalyptus camaldulensis stand (192.16±24.9 t/ha). The mean total biomass carbon stock was significantly higher in Eucalyptus grandis (267.78±73.1t/ha) than (105.52±22.8 t/ha) in Eucalyptus camaldulensis stand. While, the mean total soil organic carbon stock of Eucalyptus grandis stand was (83.94±1.5t/ha) and for Eucalyptus camaldulensis stand (86.64±6.2 t/ha). This study indicated that, there was a significant difference in carbon storage potential between both stands and therefore planting Eucalyptus grandis much better in terms of climate change mitigation.
