Macrophytic flora and vegetation of the rivers Svrljiški and Beli Timok (Eastern Serbia)

Abstract

Floristic and phytocoenological investigations of macrophytic vegetation of the rivers Svrljiški and Beli Timok in Eastern Serbia were performed. Analysis of the collected plants showed that the hydrophilous flora contains 26 species from 17 families and 21 genuses. Phytocoenological analysis showed 5 different associations from 3 alliances, 3 orders and 3 classis. Aquatic vegetation is represented by the associations Myriophyllo-Potametum and Potametum nodosi, moor vegetation by associations Scirpetum lacustris and Sparganietum erecti, while nitrophilous vegetation is represented by association Polygono-Bidentetum tripartitae. These associations have formed three clear vegetation belts: submerged, floating and emerged vegetation.
