Keywords: a community of uropodine mites was studied in the soil of a valley slope in the Massane beech-wood. Several soil features (organic matter, C/N ratio, litter mass) depended on the steepness of the slope. The density and the diversity of the community was influenced by these soil features. The highest number of mites and the highest diversity index was observed in places where litter was the most concentrated i.e., where the steepness of the slope decreased.
