The Gradac River is the first larger tributary of the Kolubara River. Situated in hilly and
mountainous region, south from the city of Valjevo, with no larger pollution sources and with gorge
which is regarded as nature reserve, this carst river could be considered as one of „nearly natural“
Serbian watercourses. The aim of this paper is to test ecological status of such „reference watercourse“
based on present aquatic macroinvertebrate communities. Macroinvertebrate samples were taken in the
May of 2015 at five localities along the Gradac and its branches (the Bukovska and Zabava Rivers).
For the ecological status assessment following metrics were applied: Saprobic Index (Zelinka &
Marvan; SI), BMWP (Biological Monitoring Working Party) Score, ASPT (Average Score Per
Taxon), Number of Ephemeroptera, Plecoptera and Trichoptera (EPT) taxa, Total number of taxa,
Participation of Oligochaeta (Tubificidae) in total community (% Oligochaeta), Number of families
and Shannon-Wiener’s Diversity Index (SWI). A total of 55 aquatic macroinvertebrate taxa were
identified. Insects were found to be the most diverse component of recorded fauna. Ephemeroptera
were the dominant insect component in terms of diversity (14 taxa) and relative abundance (40% of
total community). Values of used indices point to very good (I class) and good (II class) ecological
status of the river. This result confirms previous investigations, and supports the fact that the Gradac
River is one of a „nearly natural“ watercourses in the region.
