DIVERSITY OF DIATOMS IN THE NATURAL, MID-FOREST TEREBOWIEC STREAM – BIESZCZADY NATIONAL PARK

Abstract

The Terebowiec stream is an 8 km long watercourse which flows through the strictly protected Bieszczady National Park. The studies on bentic diatoms were conducted between 2013–2015 at three sampling sites along the Terebowiec stream and its unnamed tributary. 260 diatom taxa were identified in the streams, of which 13 taxa were considered as frequent. Chemical analysis showed good and high status of the water. In the studied samples, 27 taxa from the Polish Red List of Algae were determined.
