Abstract
This study was conducted to estimate carbon stock along altitudinal gradient of Sekele-Mariam dry Afromontane forest, North- Western Ethiopia. A systematic random sampling was employed to collect tree/shrub diameter and height, litter and soil data. A total of 60 plots with 50m*50m size each with nested plot (1m*1m) size for litter and soil were laid on the transect line. Diameter at breast height (DBH) of trees/shrubs with DBH ≥ 5cm and height were measured. Carbon stock was estimated using allometric equation and soil organic carbon was analyzed in the laboratory following Walkley Black method. The result of this study revealed that Sekele-Mariam forest had stored a total of 185.71 ton carbon/ha within its aboveground, belowground, litter biomasses and soil. The higher carbon stock in all carbon pools was found at the higher altitudinal range (2395-2460 m a.s.l.). Analysis of variance (ANOVA) result indicated that carbon stock between altitudinal gradient was not significant. The study area had smaller stock of carbon in its biomass and therefore, better forest conservation and management are the best strategy to enhance the carbon stock of the study area.
