- Аннотация: The studies have been done to reveal the structure and dynamics of forest landscapes including unique sub-Mediterranean ones within the North-Western Caucasus of Russia. Particular attention has been paid to the “Utrish” reserve, which was established in 2010 and can be a good model for studying the restoration of forests after long-term use and for developing recommendations of rational use of neighboring territories. The complex of methods such as field landscape-geobotanic profiling and mapping, including microcenotic mapping, analyses of remote sensing data of high resolution, phytomass and productivity determination, statistical analyses of intercomponent relations was used during the study. For the first time, large-scale geobotanic and landscape maps of the study area were compiled. The classification of geosystems and characteristics of the main landscapes of two altitudinal belts – the sub-boreal mesophytic broad-leaved forests and sub-Mediterranean meso-xerophytic forests and woodlands were provided. The basic regularities of the spatial organization of the landscapes were revealed. The main role in the differentiation of the landscapes and vegetation diversity was defined by tectonic and geological structure, exposure, steepness and shading of the slopes, distance from the sea and anthropogenic effect. The most complex structure is typical for the sub-Mediterranean landscapes of juniper (Juniperus excelsa, L. foetidissima, J. oxycedrus), pistachio (Pistacia mutica) and oak (Quercus pubescens) forests of the south slopes due to the ability of geosystems of seism gravitational landforms. The main features of the primary succession stages after logging, recreational use and fires in different types of forests were identified and some recommendations on monitoring and use of neighboring territories to the reserve were suggested.
