ABSTRACT
Objectives: The assessment of people on the spatial distribution, the dynamics of the main woody species and its determinant factors, the natural regeneration and preferences of species in lands was sought.
Methodology and results: A perception survey of households, i established that the woody stand is diversified enough with a wide dominance of Combretum glutinosum, Guiera senegalensis, Piliostigma reticulatum, confirming the floristic composition resulting from the woods inventory. The appreciations on the woodlands evolution showed that the most useful species were threatened because of their multiple uses. It was in particular about Pterocarpus erinaceus, Cordyla pinnata, Detarium microcarpum and Sterculia setigera. The abusive exploitation, the bush fire, the drought and the unsuitable cultural practices constitute the main reasons of species threat.
Conclusion and application: The recommended solutions emphasize the artificial regeneration (reforestation), natural (rejection/sowing) and the awareness of the populations. Species preference was related to their use rather than their importance in the medium. The choice of the favorite species was related to the middle: fields and fallow or forests and uncultivated area. The wood species regenerates and the practice of the natural regeneration was mainly the releases protection, the natural sowing and the seed trees with constraints related to the monitoring/protection, and the seedlings maintenance. The knowledge by the populations of species that colonize each land use system, the woody stand characteristics and practices advocated a strategy of restoration and / or rehabilitation of ecosystems based on local knowledge are carried out.
