Water quality assessment of the Zapadna Morava River

Monitoring of the Zapadna Morava River has indicated moderate to poor water quality since the late 20th century. This study assessed its ecological status using physico-chemical parameters and phytobenthos (epilithic diatoms), and evaluated the applicability of non-diatom algal indices. Sampling conducted at four sites in spring 2024 showed discrepancies between methods: physico-chemical parameters indicated poor to bad ecological status, while diatom indices suggested good status. Non-diatom indices aligned more closely with physico-chemical results. The study highlights the need for further research and development of national indicator taxa lists.
