摘要:The paper examines the impact of anthropogenic activ ities on the bulk densities and lev els of carbon stocks in Zorbogu, northern Ghana. The study focusedon four areas; a natural forest (FR), aplantation forest (TP), a non-burnt (UBF) and a burnt farm (BF). Simple random sampling was used to establish five 20x20m quadrats. Nested 1x1m quadrats were established within thes e for soil sample collection. Soil samples were analysed for their bulk densities and percentage carbon. Data on the diameter at breast height (cm), total tree height (m), wood-specific gravity (g/cm3) were used to estimate the carbon stocks of the community forests. Mean bulk density values increased from 1.17g/cm3 in the farmlands where burning is practiced to 1.53g/cm3in the community's natural forest. The teak plantation recorded a bulk density value of 1.36g/cm3which is lower than the value recorded in the non-burnt farm (1.50g/cm3). BF recorded the least soil carbon stock (198.72 Mg C ha-1) whiles FR recorded the highest (351.95 Mg C ha-1). There were also significant differences in the carbon stocks of the community forest for the above ground tree biomass with FR recording higher carbon stocks (71.7t/ha) than TP (29.7t/ha).
