Abstract:

The aim of this work was to study the impact of wood cutting and bush fire on the dynamics of regeneration of vegetation in the Guinea savanna of Adamawa. Floristic inventories were made by using quadrat method of two factors (shrubby and savanna), three treatments (logging without fire, with fire and control) and three repetitions (parcels). Within each savanna, 09 sites of 10m×10m were delimited using the pocket for both savannas. Data analyses with Xlstat software showed that the regeneration rate is very high in the savanna logging without bush fire. The vegetation structure of both savannas following the dispersal of species in «L» representing the evolution and the higher rate of the regeneration of species after wood logging. The Shannon index respectively in the tree savannas and shrubby savanna is 3.74% and 2.70% for the site cut without fire, 3.61% and 2.53%, for the site cut with fire and 3.75% and 2.80% for the control site. These Shannon indexes show that bush fire and wood cut influence the regeneration of the ligneous. Forbidden wood cut, uncontrolled fire, strict sanction and awareness of the population are the solution for a sustainable management of Guinean savannas.
