This study was carried out in the dense semi-deciduous production forest of East Cameroon. The objective of this work was to evaluate the impact of logging on floristic parameters through a synchronic analysis. Sampling was conducted in a control plot (unlogged) and a logged plot. Data collection was carried out using the surface method. All individuals with a diameter greater than 10 cm at 1.30 m above ground level were counted in the 20 m x 25 m plots. Nested quadrats 5 m x 5 m, oriented south-west and north-east were set up in each plot for the counting and identification of all individuals with a diameter less than 10 cm. the analysis of inventory data showed that the floristic composition was higher in the unlogged plot and lower in the logged plot. The individuals were more evenly distributed in the logged (Pielou's equitability index = 0.83) than in the unlogged plot. The study of the functional spectra showed that the flora of the two plots is dominated by Guinean-Congolese species (87.71% in the control plot and 87.53% in the logged plot) and Phanerophytes, particularly Mesophanerophytes. The dominance of sarcochorous species reveals that the main mode of dissemination in this forest is zoochory, particularly endozoochory. The presence of pleochroic species in the logged plot reveals the importance of dissemination by water in the environment. The plants surveyed are divided into five plant assemblages according to ecological parameters. Basing on the various analyses carried out within the framework of this study, it noteworthy to emphasize on the importance of forest management to the maintenance and reconstitution of the vegetation cover and, by extension, the conservation of biodiversity through post-logging assisted regeneration.
