Study of the degraded Nyárjas fen

In this study we analyzed a recently degraded Hungarian lowland wetland, the Nyárjas peatland in order to identify the main cause of its drying. we could link these hydrological indicators to the ecological status of the fen. The model results for the 1961-2010 period clearly suggest that (i) the wetland degraded due to a temporal unfavourable combination of regional groundwater depletion and decreased precipitation and (ii) could not recover afterwards despite the improvement of hydrological condtitions.
