Influence of anthropic activities on the structural changes of plants species of mount Ngaoundal
The strong pressure exerted by inhabitants on natural resources through agro-pastoral and military activities are among others the main causes of phyto-diversity degradation of Mount Ngaoundal. As a prelude to the exploitation of minerals founds in the Mount, the overall objective of this research was to investigate on how the resources of the Mount have being used. The research approach consisted of using the MARP tools and the floristic records sheets of vegetation to evaluate the different potentials of the Mount. Results indicate that, although the mining exploitation works are still to really start, the Mount is already subject to zoo-anthropogenic activities such as agriculture (13.94%), botanical healthy (12.98%). %), or ecotourism (11.50%). The floristic surveys enabled the identification of 6773 plants belonging to 62 species, 45 genera and 32 families. The Mount is found to be very diversified, with the ecologically dominant and important species recognized as Daniellia oliveri (21.65%), Piliostigma thonningii (21.03%), Terminalia glaucescens (18.24%) and Hymenocardia acida (14.23%). Species such as Dombeya quinquesete var. Senegalensis and Xylopia parviflor are rarely found, whereas others like Daniellia oliveri, Piliostigma thonningii are preferential. The South slope was the most densified, unlike the East, which was the most diversified. The structure of species in height along the slopes was the "L" shape, which indicated a very highly significant difference (p <0.005) between the height classes per slope. Depending on the altitude, 37.58% of species had heights ranged between [0 - 0.5[m, while only 8.21% of species had height comprised between] - ∞, 8[. Altitudes 200m and 600m showed vertical structures oft the "L" shape, whilst vertical structures in inverted "U" shape were found at 400m altitude.
