The study  carried out in the Mayo-Danay, Mayo-Kani, Mayo-Sava and the Logone and Chari Divisions in the Far North Region Cameroon, are our target within the framework of the study of the structure, dynamic of regeneration and the ecological characterization of vegetation of shrubby savannahs, woody savannahs, protected areas and sacred forests in the soudano-sahelian zone. On the whole, 48 hectares were chosen at random with 12 hectares per Division. The study of the dendrometric parameters was observed on the parcels of 100x100 m. The analysis of the data by XLSTAT and STATGRAPHIC PLUS 5.0 showed that the vegetation has a structure of inverted “U” according to the height of the trees of four Divisions and four types of vegetation. It has an “L” structure according to the DBH. The sacred forests have a high rate of number of stems in the Mayo-Kani ( 2280 stems/ha in  first year). The lower number of stems is observed in the shrubby savannahs of Mayo-Sava (725 stem/ha in first year). It exists some important positive correlations between the density of stems between the Mayo-Kani and Mayo-Danay Divisions (r=0.98), the Mayo-Sava and the Logone and Chari Divisions (r=0.88). The Anogeisus leiocarpus (30.16 MK1) species presents an index with satisfying and important ecological value while the lower value is observed in the specie of Mitragyna inermis (0.01 MK1).   The Mayo-Sava Division is the most affected by the deforestation and it would be judicious to intensify the reforestation in this area.
