Western Niger lateritic plateaux formally occupied by tiger bush are mainly secondary ecosystems affected by crusting and soil compaction that impedes infiltration and induces intense erosion, which hampered lowlands millet fields. Restoration of these plateaux is essential, but, failure is frequently reported about early species establishment. It’s therefore necessary to examine the mechanisms and factors of early plants recovery which areimportant for vegetation restoration. Vegetation data have beenrecorded in 31 plots, at four sites with similar environmental characteristics and different land use histories:Unrevegetated area, 1-3-years old revegetated area,6-years old revegetated area and 14-years old revegetated area.We also measured 16 environmental variables in each plot to examine the driving forces of succession and the vegetation-environment relationships. TWINSPAN results revealed that plant species could be classified into six plant communities representing 4 succession stages.
Le but global et à long terme du projet en matière d’environnement et de développement est d’affronter les problèmes corrélés de la pauvreté rurale, de l’insécurité alimentaire et de la dégradation des terres en promouvant et en multipliant les pratiques durables de gestion des terres, dans le but de restaurer, de soutenir et de renforcer les fonctions productives et protectrices des ressources de l’écosystème dans la région de Maradi.
