THE NATURAL MONUMENT OF THE IVANOVO REGION "OZERKI. RUSALOCH’I LAKES": CURRENT STATE, DYNAMICS, FEATURES OF PROTECTION

Abstract

Background. Results of studies of the natural monument of the Ivanovo region "Ozerki. Rusaloch’i lakes" are presented. The study of lakes of karst origin is topical, since these lakes are important for protection as indicators of the ecological state of the territories. The aim of the studies was to describe the main morphometric parameters of two karst lakes in the Shuisky district of the Ivanovo region, to study the characteristics of flora and vegetation, to identify rare species and dynamic trends. Materials and methods. The studies were carried out in 2018–2022. Depths were measured, digital elevation models of the lake bottom were compiled using GIS and spatial analysis technologies. Floristic studies were carried out by the traditional route-reconnaissance method, special attention was paid to rare species of vascular plants and a description of the state of their populations. Results. As a result of the research, limnological indicators were characterized, the genesis of lake basins was determined, and bathymetric schemes were given. The flora and vegetation of this protected area are briefly characterized. By 2023, there are 257 species of vascular plants, belonging to 5 divisions, 6 classes, 64 families and 173 genera, as well as 11 species of mosses. 7 species of vascular plants are included into the Red Data Book of the Ivanovo region, 23 are rare and need protection. The state of populations and trends in the dynamics of rare plants are briefly characterized. Examples of spreading invasive plant species are given. Conclusions. The obtained results of field research were used in compiling the passport of this protected area.
