Newly‑formed aquatic habitats, such as gravel pit lakes in river floodplains are usually colonised by macrophyte species few years following the gravel extraction. Together with native species, invasive hydrophytes may also create stable stands and therefore affect vegetation composition. The aim of this study was to determine the potential influence and correlation between the total cover of invasive macrophyte species and macrophyte vegetation metrics (Shannon diversity index, species richness, total macrophyte cover, number of macrophyte functional groups, number of charophyte taxa and relative charophyte cover) in gravel pit lakes along the Drina River floodplain (Serbia). Field research was carried out on 49 survey sectors, distributed at 14 newly‑formed gravel pit lakes (5‑10 years after the final gravel extraction), during the summer months of 2015 and 2016. Vegetation data was collected in accordance with the Pan‑European standard for the sampling of macrophyte vegetation in la...kes, using the UKTAG LEAFPACS (Lake Assessment Methods, Macrophyte and Phytobenthos). Invasive aquatic plants were recorded on 12 gravel pit lakes, including 38 surveyed sectors, with the relative cover value of up to 20 %. Three alien hydrophytes were recorded: Elodea canadensis Michx, Elodea nuttallii (Planchon) St John and Vallisneria spiralis L. The most frequent and abundant one was Vallisneria spiralis, which was recorded on 31 surveyed sectors. Apart from the relative charophyte cover and the number of macrophyte functional groups, which showed no correlation, all other macrophyte metrics showed weak to moderate positive correlation with the relative cover of invasive species. This finding suggests that the establishment of macrophyte vegetation may not be significantly affected by invasive species at this early successional stage.
