This study was performed to estimate the influence of sub-surface dam construction on the vegetation; which was constructed for dry season water resource development to struggle against desertification In a part of the western African country of Burkina Faso. It was expected that sallow groundwater blocked by the dam would have influence on the growth of the tree in the flood field. Therefore, the behavior of tree growth in both up and down stream areas were investigated. The results showed that the difference of the moisture condition of soil affected by the dam, led to the difference in the time of the fallen leaves and the quantity of leaves and flower of the tree. A clear difference wasn't seen, however, to the force and form of the tree and the quantity of the fruit
