Abstract
Forest plays a crucial role in climate change mitigation by sequestering and retaining carbon in above and below-ground biomass of trees, dead tree and deadwood biomass, litter biomass, and soil. Thus, the study was conducted to estimate the carbon stock potential of Godebe National Park, North Western Ethiopia. The field data were collected through systematic random sampling techniques from the 20 m ¡Á 20 m area of 44 sample plots. The above-ground biomass, below-ground biomass, deadwood biomass of the study area was collected from 20 m ¡Á 20 m area of the main plot, while the soil sample and litter biomass were collected from 1 m ¡Á 1 m area of subplots, which located at the four corners and one at the center of the main plot. The carbon stock of different carbon pools was estimated using different selective allometric and mathematical models and analyzed by statistical package for social science (SPSS) software version 23. The result showed that the mean carbon stock of each carbon pool such as above-ground carbon, below-ground carbon, deadwood carbon, litter carbon, and soil organic carbon accounted for about 338.893, 67.779, 5.43, 2.56 and 109.34 t/ha, respectively. The carbon stock variation along different strata (Acacia Woodland, Combretum Terminalia woodland and Riverine Forest) indicated that statistically significant effect was observed on carbon pools of the study area at ¦Á (0.05). The ultimate result showed that the study area stored and sequestered 523.948 ton of carbon per ha and 1922.887 tone CO2 equivalents per ha respectively. Although the national park is newly established it has a great potential on carbon sequestration and such biodiversity conservation effort should be strengthened.
