Abstract: The natural regeneration of prime timber species with high economic potential is studied in the Mpoh forest, in the northern sector of the Léfini reserve.Although a source of economic and self-subsistence for local residents, the natural regeneration of these forest ecosystems has received very little attention.The floristic inventory was carried out in three one-hectare quadrats, in which (i) the d 1.30 of ligneous plants 1 cm ≤ d 1.30 < 10 cm, d 1.30 ≥ 10 cm and seedlings ≥ 30 cm in height were counted and measured; (ii) the degree of canopy openness, litter thickness and herbaceous cover.The inventory reveals 1208 individuals for 36 species and 20 families, i.e., 118 seedlings of height ≥ 30 cm; 769 individuals of 1 cm ≤ d 1,30 < 10 cm and 321 of d 1,30 ≥ 10 cm.Structural parameters favor Petersianthus macrocarpus as dominant in the 1 cm ≤ d 1.30 < 10 cm and d 1.30 ≥ 10 cm diameter classes, in density (89 trees.ha-1 ) and basal area (7.137 m².ha -1 ).In contrast, Entandrophragma sp.dominates the seedling class (h ≥ 30 cm).The bioecological indices highlight a difference in the floristic composition of the compartments.Natural regeneration, dependent on light and litter thickness, is generally good.Depending on the socio-economic value of taxa with difficult natural regeneration, intervention may be necessary.
