The Influence of Periodic Fires on the High Guinean Savannas and the Carbon Stock in Cameroun

The influence of periodic fires in the high Guinean savannas Cameroon on woody plants and carbon stock is poorly documented. To fill this gap, work was carried out with aim contributing to assessment effects cover stock. methodology used consists carrying semi-structured household surveys floristic inventories Arrondissement Ngaoundéré III Ngan’ha, Department Vina. A total 50 households were interviewed at a rate 25 per Borough according questionnaire prepared beforehand. For botanical inventories, 02 types savannah selected: regularly burnt (shrub savannas, wooded savannas) those not burned for least 10 years tree savannas). choice control made indications peasants. In each them, 1km x 20m transects covered diameter breast height (dbh) measured using dbh meter 1.3 m from ground large trees. 30 or cm shrubs shrubs. results show that climate change palpable area. rains are increasingly rare, drought has become severe agricultural calendar no longer respected. specific diversity relatively low 51 species having been inventoried, divided into 46 genera 23 families. Savannahs produce more biomass than burnt. perfect illustration given by non-burnt Ngaoundere an above-ground root 102.23 t/ha 20.70 respectively. Annona senegalensis (1.27 tC/ha) massively sequestration Thus, acting availability plant biomass, contribute erosion biodiversity. Adequate measures urgently needed limit bushfires.
