Abstract:

The present research work aims at: i) evaluating the floristic arrangement and the ecological specification of the forestry galleries; ii) examining the structure of those forestry galleries; iii) appraising the regenerating rate in the forestry galleries and iv) examining the supply in the forestry gallery species. The strutting ligneous stocktaking were carried out on ten plots of land of 20x20m arranged along each forestry gallery. The data collection by EXCELL and XLSTAT software showed out that the ligneous species listed out were merged/grouped together in 68 species and 26 families. The Moraceae family presented the highest number of species (09). The Uapaca togoensis is the most abundant species with a relative frequency of 25.63%. The specific highest specific resource is found in the Vina division (38 species) with the Shannon diversity index of 4.25 bits. The structure of the forestry galleries has the “L” shape according to the height of the trees. The medium height of the ligneous species is found in the Mbére division (51.30cm ±17.38). The highest regeneration rata is found in the Djerem division (12.21%) and the lightest devastating rate is found in the Mayo Banyo division (20.80%). The multiple component analysis (MCA) pointed out that grouping. The anemochores are considerable in the Faro and Deo division (69±28), While the hydrochores in the Mbére Division (89±21) and the zoochores in the Djerem division (60±22). The diaspore dispersal strengthens the regeneration of the forestry galleries.
