The study of sub-Mediterranean landscapes of the North-Western Caucasus, unique for Russia in current conditions of increased recreational impact and climate change with an increase in average annual air temperature and precipitation contrasts is especially relevant. The goal of this research is to re-veal structure and dynamics of the coastal sub-Mediterranean landscapes of the Doob and Abrau peninsulas of the Black Sea, including the territory of the Utrish Nature Reserve as a background. Field measurements on transects crossing the seaside slopes of ridges with various types of shores and multispectral satellite images (Landsat-8) were used to compile large-scale landscape maps (1: 25,000) and more detailed profiles as the basis to determine the factors and patterns of formation of coastal geosystems. Some typical transects also included the near-shore parts of the sea. Repeated observations at monitoring sites since 2015 were carried out to study geosystem dynamics after fires and recreational impact, activity of exogenous processes due to the climatic contrasts and seasonal changes in the land-sea zone. The revealed high heterogeneity of the spatial structure of coastal landscapes is associated with the complexity of the geological and geomorphological basis, including numerous seismogravitational landforms of different sizes and ages. Along different types of shores, which complicate the landscape structure, unequal underwater bottom complexes are formed with individual fea-tures of seasonal and interannual dynamics. The predominance of abrasion and denudation shores, composed of flysch and landslide deposits, deter-mines the activity of exogenous processes, dynamics and gradual destruction of the coastal landscapes, especially rich in Mediterranean flora species. The main features of landscape successions after fires of different years and recreational impact have been identified for typical Mediterranean communities. Juniper (Juniperus excelsa M.Bieb., J. foetidissima Willd.) forests are distinguished by the least resistance to impact and the longest period of their recovery. The conducted studies are part of the monitoring of sub-Mediterranean landscapes for integrated territory planning.
