The article examines the territory of the Ilmenno-Bugrovy district of the Volga River in the Astrakhan region from the standpoint of protecting the unique nature of this territory. The role of anthropogenesis in changing landscapes over the past decades is revealed. This area is unique from the point of view of nature, which under the influence of anthropogenesis has changed dramatically for a number of reasons, such as climate change, irrational use of natural resources by the local population, etc. Of particular concern is the hydrogeological state of the underlying Ilmen and adjacent territories. In recent decades, one of the most important factors in the violation of the hydrological regime of the studied territory, especially in the deltaic and near deltaic regions, is a sharp shortage of drinking water in the Ilmeny and a reduction in the area of agricultural land. This leads to the activation of the processes of drying out, dying off and salinization of most Ilmen, and even to their complete disappearance. Conclusion. the Majority of reservoirs ilmenno-bugrovoi area are in extremely poor environmental condition. The volume of water in them is sharply reduced, and many of them have ceased to exist, due to longterm and poorly controlled economic activities in recent years. This led to radical changes in natural landscapes and reconstruction of the territory of the ilmenno-bugrovy district.

Key words: Ilmenno-bugrovoy region, West pidstepne ilmenite, landscape, hillocks of Baer, libogrove reduction, regulation of the Volga river, salinization, and desertification
