The results of research on biological diversity in a section of the Chepelarska River and the territories adjacent to it, subjected to anthropogenic pressure, are presented. The studied area (water body code BG3MA500R103, river type R5Semi-mountainous type in Ecoregion 7 Eastern Balkans) falls entirely within protected area BG0000194 "Chaya River". It is located along the lower section of the river before it flows into the Maritsa River (Eastern White Sea Basin). The types of natural habitats and their ecological status are presented. Regarding the registered 45 species of higher plants and 22 animal species, the nature protection status and the species with resource importance have been determined. The results from the ecological monitoring of the freshwater ecosystem based on physicochemical elements (dissolved O2, pH, electrical conductivity, Ptotal, N-NH4, N-NO2, N-NO3, P-orthoPO4, Zn, Cu, Pb, Cd) and ecological quality element macrozoobenthos, after applying the established standards are discussed. Measures to improve the ecological condition of the studied area are indicated.
