This study aimed to estimate the carbon sequestration potential and soil properties of the Abijata-Shalla Lake National Park in Ethiopia. The random sampling techniques were used for dead wood, litter, soil, woody trees and herbaceous) under the different grazing pressure. The DBH (> 2cm) and height of woody trees were used for biomass estimation with allometric equation and the dead wood volumes by smallian formula. The specific wood density was used for each species to estimate the total biomass. The high proportion of (45.35%) woody species found in (10-20cm) DBH classes in the highly grazed area and (38.78%) in the low grazed area. The densities of woody trees decrease as the height and the DBH increases in the study area. The overall mean of carbon stock of aboveground, belowground, dead wood and litter were 112.3, 22.5, 6.9 and 0.95 t C ha-1, respectively. The soil physical properties (sand and silt) and the electric conductivity (EC) PH, Av.p, CEC shows the significance difference (P < 0.05) with grazing pressure and across soil depth. Generally, the overgrazing has negative impacts on the vegetation biomass and the soil quality. Therefore, the sustainable management, such as destocking of livestock, rotational grazing and intervention of community based conservation was suggested to sustain the ecosystem health and enhance the carbon sequestration potentials.
