Ecological characterization of the Vegetation in the Sudano-Sahelian Zone of Cameroon
Journal Title: Scholars Academic Journal of Biosciences - Year 2017, Vol 5, Issue 3
Abstract
The study was carried out in the Mayo-Danay, Mayo-Kani, Mayo-Sava and the Logone-Chari Divisions in the Far-North Region of Cameroon, to ecologically characterize the shrub savannahs, wooded savannahs, protected areas and sacred forests of the sudano-sahelian zone. In total, 48 hectares were chosen at random with 12 hectares per Division. The experimental design was a split-plot (4 x 4) x 3, where the 4 Divisions represented the main factor and the 4 types of vegetation the secondary factor.Dendrometric parameters (DBH and number plant species) where observed on 100m2 plots. Results indicate that vegetation has an “L” structure, obtained when the DBH was taken into consideration. Guierasenegalensis, Anogeissusleiocarpus and Combretumcollinumshowed ecological indexes with high values (35.78, 34.39 and 32.87 respectively), whereas a lower index was obtained for Boswelliadalzielii (0.01), Lonchocarpuslaxiflorus (0.01) and Steganotaeniaaraliacea(0.01). The Mayo-Sava and Logone-Chari Divisions were the most affected by the deforestation based on the density of species. In the framework of sustainable and rational development of natural resources in the sahelian area, it is suggested to intensify reforestation in these two Divisions.
