Abstract

Forest concessions granted to Cameroon are of growing interest for ecological, economic and social management. Despite the efforts made on forest carbon stocks estimates, little information and field data exist on post-logging effects on the carbon footprint. The present study carried out in an annual cutting plate 6-4 (1 167 ha) of the Forest Management Unit 08 003 aim to estimate carbon stocks before and after logging and to establish the carbon footprint. For the estimation of pre-logging biomass, the non-destructive method was used and trees inventory of diameter ≥ 10 cm was carried out in 21 plots of 250 × 20 m. Field measurements (width and length of logging roads, logging gaps and log yards) were made to calculate all the areas and carbon stocks affected by logging operations. Pre-logging carbon stocks were estimated at 202.06 tC/ha. The results from measurements of the different types of forest infrastructure show that logging under a simple management plan contributes to 12.11 % of the degradation of the cutting area (141.3 ha), which corresponds to 12.16 % of forest carbon (28 570. 86 tC). The skid trails represent the principal source of forest degradation (63.58 ha), which corresponds to 12,428.32 tons of carbon impacted. An increase in 71.78 % of carbon stocks in dead organic matter was observed. These results show that the use of sustainable management models and improved logging techniques would significantly reduce the area destroyed and also the carbon stocks.
