The woody flora of the National Park of Manda in the Sudanian area of Chad has been characterized between October and December 2016 to know its floristic diversity, and to quantify its aerial woody biomass. The transect and quadra method (1m x 1m) were simultaneously adopted for this study. The pan-tropical equation of Chave et al. made it possible to evaluate the carbon stocks in different sites. The study of the flora species identified 45 species divided into 37 genus and 21 families for an average population density of 355 individuals/ha. Three classes of the diameter dominate the settlement: class ≤ 10 cm; class of 10-20 cm and class of 20-30 cm. The height classes belong to the class of plants ≤ 4 m; and at last having a height ≤ 7 m. The basal area was 5.86 m2 / ha. It appears that the woody components store 23.82 ± 0.01 tC / ha, the undergrowth 0.14 ± 0.01 tC / ha and the litter 0.56 ± 0.01 tC / ha. This research is a contribution to the REDD+ process (Reducing Emissions from Deforestation and Forest Degradation).
