Abstract: The present study figured out net annual accumulation of carbon in coniferous forest of Dir Kohistan. In present study the annual diameter growth (cm), mean annual increment (m3 ha-1yr-1) total gain and loss in biomass in biomass (t ha-1yr -1) and total gain and loss of carbon (t ha-1yr -1) was assessed. The results of the study showed that Pinus wallichiana has mean maximum annual diameter growth of 0.28±12cm yr-1 while minimum growth was recorded in Abies pindrow (0.23±0.056 cm). The mean annual increment of the forest was 5.07m3 ha-1yr-1, while total estimated biomass gained by the forest was 3.31t ha-1yr -1. The mean input of biomass C stock was 1.65 t ha-1yr -1. The study revealed that total biomass removal from the forest in the form of fuel wood, timber consumption and illegal cutting was 2.97t ha-1yr -1 that accounts for 1.48 t ha-1yr-1 of carbon losses. The results of the study concluded that the coniferous forest of Dir Kohistan can sequester mean carbon of 0.17 t ha-1yr -1 from atmosphere. The results of the present study confirmed that the forest of the study area acts as a net sink of carbon.
Key Words: Dir Kohistan, Coniferous forest, Carbon Accumulation
