“…This area is subjected to a Guinean climate characterized by two seasons: A dry season from November to March and a rainy season that begins in April and ends in October. The human population of the locality is mostly made up of herders (Bororo and Fulbe) and farmers (Mboum, Dii, and Gbaya) (Fawa et al, 2015). This area is covered by shrubs trees savannahs dominated by Daniella Oliveri and Lophira lanceolata (Letouzey, 1968).…”

Sclerocarya birrea (A. Rich.) Hochst is one of the woody plants of the soudano-Sahelian zones, with great socioeconomic importance. The local populations over-exploit this species for their daily socio-economic needs and this endangered its durability. The objective of this study was to contribute to the domestication of this species by the low-cost technique of Root Segments Cuttings (RSC). The substrates sand/sawdust and dark soil/Sawdust have been inoculated with 0, 10, and 20 g of mycorrhizae. The experimental design was a split plot with 4 repetitions. The experimental unit is of 10 cuttings. The results show that the best substrate for the budding of the RSC is the mixture of Sand/Sawdust (37.77±17.15%). The appropriate dose of mycorrhizae for the budding of the RSC is 10 g (33.33±21.6%). For the height of the aerial axes, a satisfactory result was obtained in the dose of mycorrhizae of 10 g (3.43±2.40 cm). Concerning the number of the leaves, the maximum is recorded in the RSC inoculated with 20 g of mycorrhizae (3.60±1.36). The analysis of variance did not show a meaningful effect for the treatments (0.54>0.05), as well as for the substrates (0.76>0.05). Regarding the rooting of the cuttings, one must notice that the best substrate for the number of newly formed roots is the mixture of Sand/Sawdust (2.22±1.01) while the dose of 20 g has much allowed the appearance of roots (3.41±1.24). The best substrate for the length of the newly formed roots is the mixture of Sand/Sawdust (2.9±1.3 cm), whiles the proportion of 10 g has permitted a lot of the growth of roots (4.24±1.69 cm) as far the plum tree of Africa is concerned. These results show that improving some parameters at S. birrea is possible by vegetative propagation.

Plant dynamics is a natural process that occurs in the ecosystem. This dynamic becomes abnormal in the presence of human pressure. The vegetation of the district of Mokolo (Cameroon) faces many anthropic factors that disturb its steady evolution. This work aims to evaluate the different factors that influence the vegetation dynamics in the south of the Mokolo District. All traces of anthropization were identified on all woody species in a rectangular plot (20 m x 100 m). All individuals with a height ≤1.30 m and a Dhp less than 10 cm were considered regenerating individuals. Among the main plant factors, dynamics identified, regeneration, spread type, phytogeographic type have positive impacts while logging, debarking, pruning, grubbing, trampling and burning have negative impacts. Regeneration is the main positive natural factor with the highest frequency in wooded savannas (321±95%). Timber harvesting is the main negative anthropogenic factor with a higher frequency in the home garden (85.00%) and the shrub savannas (68.66%). To reduce the negative impacts and increase the positive impacts, the government must implement reforestation projects in this ecologically fragile area.
