The climatic processes observed during the last three decades have a significant effect on the biotic and abiotic elements of Hungarian landscapes. According to our research, the changes of hydrological factors significantly influence the landscape in a relatively short period of time. The water shortage observed in the Danube-Tisza Interfluve has a stress-like effect not only on the vegetation but on soils and landcover at many places. We managed to show that the area of wetlands is continuously decreasing. The soils sensible to hydrological effects have transformed and we could observe ‘forced migration’ in case of certain habitat types.
