The role of forests in hydrological processes on the Great Hungarian Plain is still a subject of debate. Among the causes there are numerous and highly variable local factors taking part in the processes.
This research investigated the impact of forests on groundwater levels and ion transport of the soil since 2012 on 108 study sites, using one-time soil sampling, forest stand measurements and groundwater monitoring.
Results in general supported the assumptions of the hypothesis in correlation with groundwater depression and ionaccumulation under forest stands. Meanwhile the same results highlighted that different water-uptake strategies of different tree species and other local factors (topography, soil texture) highly influenced the processes.
Consequently it is not correct to evaluate the impact of forest stands exclusively by their increased evapotranspiration. For this purpose complex approach is necessary in which groundwater monitoring and investigation of ion transport also could be used as useful instruments.
Keywords: hydrological regime of forests, watertable depression, ionaccumulation
