Forest management practices such as prescribed burning and partial thinning are routinely used to achieve undergrowth control in forest ecosystems. Prescribed treatments influence the physical and chemical properties of soils and change the balance of nutrients such as carbon. This study was conducted in order to identify the sinks and sources of carbon in disturbed forest ecosystem to which three burning and three thinning patterns were applied. Soil and litter samples from the treatment plots were collected for routine and nutrient analyses prior to and immediately following the disturbance. Changes in carbon distribution in forest ecosystems were identified and the impact of burning and thinning on carbon sequestration potential was accessed.
