A GIS-based model for testing effects of restoration measures in wetlands: A case study in the Kampinos National Park, Poland

► The degree of degradation of wetland vegetation and soils can be related to groundwater conditions. ► Established relation between soils, vegetation and groundwater allows using the latter as a predictor. ► Exclusion of the existing drainage system can cause positive effects on wetland vegetation. ► Other considered restoration scenarios do not show the potential of change in wetland state. ► Presented approach contains uncertainty which cannot be easily quantified for soil and vegetation mapping.
