In Peru, greater emphasis has been given to research on Amazonian forests. However, there is a great variety of Andean ecosystems that have not yet been studied and those conserve an important biological diversity. The aim of this study was to compare the alpha (α) and beta (β) diversity indices and the relative abundance of the medium and large mammals’ community in both slopes of the northern sector of the Cordillera Blanca (Yungay province) located in the National Park Huascarán, in an altitudinal gradient from May to September 2018 (dry season). Additionally, it was sought to find habitat and human influence that are related to the presence of the registered species. Ten sampling sites were established, five for each slope, and two camera-trapping stations were placed at each site from 3327 to 4712 m. a. s. l. The effective sampling effort was 1300 days/camera trap. The specific richness for the eastern and western slopes was eight species in each. The species with the highest relative abundance index on the eastern slope was Lagidium viscacia, while on the western slope it was Odocoileus virginianus. The similarity in the composition of mastofauna species registered between the western and eastern slopes is 60%. Regression analyses suggest that the altitude gradient explains the record of these species; however, the richness and relative abundance of species along the evaluated altitudinal slope did not show a particular trend. The information obtained in this research is useful to improve management and conservation strategies of the species and contributes to the growth of knowledge about the medium and large mammals’ community that inhabits the Huascarán National Park.
