The ecology of a species is a fundamental aspect in its sustainable management. The objective is to study the ecological and floristic characteristics of plant formations with D. mespiliformis. The study was conducted in western Niger along the main tributaries of the Niger River crossing two agroecologicals compartments. Abiotic factors and forestry data where collected in 220 plots of 2500 m2. Thus, the species is present in all types of soil in the area near streams. The area is moderately diverse with 41 woody species dominated by D. mespiliformis with 50% of Importance Value Index. The Shannon diversity index was 2.61 in Dargol and 2.19 in Goroubi and the Sorensen similarity index between the two zones was 0.62. The density of D. mespiliformis per hectare is 46.04 in Dargol and 33.19 in Goroubi. The demographic structure of its population of all species shows a dominance of small diameter individuals evolving into sawtooth characterized by anthropogenic pressure. These results constitute a scientific basis for the sustainable management of this food and multi-use species, which is one of the species in decline in the area.

Abstract
The ecology of a species is a fundamental aspect in its sustainable management. The objective is to study the ecological and floristic characteristics of plant formations with D. mespiliformis. The study was conducted in western Niger along the main tributaries of the Niger River crossing two agroecologicals compartments. Abiotic factors and forestry data where collected in 220 plots of 2500 m2. Thus, the species is present in all types of soil in the area near streams. The area is moderately diverse with 41 woody species dominated by D. mespiliformis with 50% of Importance Value Index. The Shannon diversity index was 2.61 in Dargol and 2.19 in Goroubi and the Sorensen similarity index between the two zones was 0.62. The density of D. mespiliformis per hectare is 46.04 in Dargol and 33.19 in Goroubi. The demographic structure of its population of all species shows a dominance of small diameter individuals evolving into sawtooth characterized by anthropogenic pressure. These results constitute a scientific basis for the sustainable management of this food and multi-use species, which is one of the species in decline in the area.
