Diatoms are unicellular algae, worldwide spread, live in many aquatic habitats and they are dominant in phytobenthos. Phytobenthos and macrophytes are one of the biological quality elements in the assessment of ecological status of waterbodies, according to the EU Water Framework Directive. Investigation of the diatom biodiversity of the Oskova River, which flows through the Konjuh protected area in its upper stream,, was based on epilithic communities. The research included sampling of benthic diatoms, analysis of physicochemical parameters, permanent slides preparation and identification of taxa. In total, 106 taxa have been recorded. The most dominant genera were Achnanthidium, Cocconeis, Amphora, Nitzschia, Navicula, and Gomphonema. The most abundant taxa were Achnanthidium minutissimum, Achnanthidium pyrenaicum, Cocconeis euglypta, and Cocconeis lineata. The Shannon Diversity Index (H’) was in the range from 1.0 to 3.3. Epilithic assemblages in the Oskova River which flow through the Konjuh Protected Landscape area showed high biodiversity of diatoms. The lower part of the river flow had lower species diversity, a well as different taxa dominance.
