The article presents data on the registration of two mammal species: the jackal and the raccoon dog. The aim of the research was to evaluate the jackal and raccoon dog populations in the Astrakhan Reserve as well as the impact of anthropogenic transformation of the environment. The research accounted for the distribution and redistribution of these species in the territory of the Astrakhan Reserve in 2021 and 2022. The counts were carried out along the coastal strip of watercourses, where the traces of the presence of these species of mammals were identified. Their density was not calculated transect-wise, but per linear kilometer. The article uses cartographic data to assess the species distribution over the territory. It provides a detailed description of their distribution principles over the territory and their density in specific areas. Based on the obtained data, the article provides relevant conclusions.
