Summary : This study is a preliminary to the establishment of management techniques, water and soil conservation, protection and restoration of soil in the Sudanian zone (medium yearly rainfall 1,000 mm). The woody resources of the Kou basin bank are undergoing rapid degradation. In order to stop this degradation, a characterization of the soil pedology, a description of the state of soil surface using the “line intercept” method and a complete vegetation inventory have been carried out. The results revealed the existence of four types of soil. The study of elementary surfaces showed that only 40.8% of the area of the site could be conducive to infiltration. The inventory of woody plants shows that the vegetation consists mainly of Caesalpiniaceae, Combretaceae, Rubiaceae, Annonaceae, and Mimosaceae. The evolutionary trend of the woody vegetation has been positive in all the plots, which shows the possibilities of rapid restoration of the site. |
