Growing household demand for fish is having an impact on the volume of wood used to make pirogues, assegais and pirogues, assegais, and fish smoking. The wood potential of land-use systems (LUS) is declining irreversibly, both in the unprotected forest (FNP) on the outskirts of the Lom Pangar Lom Pangar Dam (PBLP) and in the Deng-Deng National Park (PNDD). (PNDD). Against this backdrop, a study was carried out to assess the impact of the impact of fishing activities on the structural characteristics and regeneration potential of three woody species with high use value or key species, found in the land-use systems (LUS) of the peripheral (SAT) on the outskirts of the Lom-Pangar dam (East Cameroon), namely Entandrophragma cylindricum (Sprague) Sprague or sapelli (Meliaceae), Mansonia altissima (A.Chev.) A.Chev. or bété (Malvaceae) and Triplochiton scleroxylon K.Schum. or ayous (Malvaceae). Floristic floristic inventories, considering all individuals from the seedling, and adult stages of the target species were carried out along 20 5 km x 20 m transects, equidistant from each other by 200 m. 20 plots of 250 m x 20 m (i.e. 0.5 ha) were set up along each transect, each subdivided into sub-plots of 20 m x 20 m, at which observations were made. Out of a total of 24861 individuals surveyed during the study, 11363 (45.7%) belonged to these three species, including 4275 individuals in the adult stage. The average basal area (BA) was 5.97 ± 1.43 m²/ha in the PNDD, compared with 4.40 ± 0.7 m²/ha in the FNP. T. scleroxylon has the highest basal area value relative to the mean in the PNDD, with ST=54.33 ± 13.01 m2/ha, compared with 17.97 ± 4.30 m2/ha in the NPF. The structural characteristics (diameter and height) of these three species are closely linked to land-use systems, where their values are higher in the PNDD than in the FNP. From a regeneration point of view, only sapelli shows relatively difficult regeneration at seedling (0.42%) and intermediate (3.44%) stages in the SATs concerned by this study.
