Résumé :	Atriplex halimus is a plant introduced in Algeria, with the intention to enhance arid and semi-arid areas. The purpose of this work was to assess its effect on physical, chemical, and biological characteristics of soils. Three different sites were selected according to the universal altitudinal gradient and north-south transect. We compared the characteristics of two soils; the first one was planted with the studied species and the second one was the control open space.Results showed significant differences between both studied soils. The first was characterized by a high level of organic matter, a significant increase of CEC and cations correlated with the clay content of soil. Concerning the soil fauna, we noticed an increase in biomass and in density of all individuals particularly in low altitude stations, where soils are more fertile.
