Since the Neolithic he went through domestication, artificialization of the soil, construction of terraces on slopes, urbanization and overgrazing. The intervention of man and his cattle impacted unevenly media components of the environment but the most visible elements are biotic and among them the soil. This study reveals the extent of this intervention by the disturbance of the soil (compaction, erosion). The determination of the packed soils surface (in m² ) and their weight (in kg) is based on using the profile method which consists in metric measurements on 10 points located in a path created by man and his flock on a distance of 100 m. The interpretation of results by the Anova 1 and the PCA has clarified the affinities that exist between, on one hand, the compacted soils of the different stations, and, on the other hand to highlight the anthropozoogenic impact on the soil of  Chamaeropaie. https://www.biotech-asia.org/vol13no3/anthropic-impact-on-soil-of-the-chamaeropaie-in-tlemcen-region-western-algeria/ Chamaeropaie; Compaction; Anthropic Action; Statistical Study; Tlemcen Mounts
