Abstract

We studied six oxbow lakes along the River Drava with the Kohler-method. Oxbow lakes were chosen, in which occurences of Nymphaea alba were mentioned earlier. In comparison to the former studies, the quantity of Nymphaea alba has decreased dramatically in most oxbow lakes. Moreover, several other water-weeds have disappeared. Probably, this problem is caused by the settlement of Ctenopharyngodon idella, the grubbing-up of water-weeds, the pollution from the nearby cultivated fields and the fact that nature conservational aspects are not considered in the management of the lakes. The invasive weed species have mostly spread at Bresztik and Zalátai Ó-Dráva while at the other oxbow lakes, their quantity has been found generally low. Among the invasive species, Solidago gigantea seems to be the most dangerous.
