Abstract

The formerly widespread wetland habitats and floodplain forests are in danger today, as the number of such places has been sharply decreased in the river Danube due to the lowering of the groundwater level caused by the river regulation works. The statistical multivariate data analysis of the coenological surveys that were carried out in floodplain forests - being developed on floodplain soils - in two distant parts of the Hungarian Danube section revealed that the recorded quadrates of the two islands mainly differ from each other in species composition and the ratio of their most characteristic species. According to the nature conservation assessment of the forests, the most natural plant associations of the islands are the willow gallery forests (Leucojo aestivum-Salicetum albae). This result is also supported by the degradation values. It could be also connected to the fact that willow gallery forests are situated in the lowest parts of the floodplains that are the most flooded places, therefore only a few alien species can appear as competitors due to the extremely high soil moisture values and the long lasting water coverage.
