    Opis:
    An analysis of the dynamics of groundwater levels in the Groundwater Dependent Ecosystems (GDEs), which cover a vast part of the middle Vistula River valley in central Poland was carried out. The study area, typical of large river valleys, was investigated by detailed monitoring of groundwater levels. Based on statistical analysis and the geostatistical modeling of monitoring data for 1999–2013, the range and dynamics of groundwater level fluctuations were determined for the entire interval and for the vegetation periods. The values of retention and infiltration recharge in various periods were compared with average values, indicating intervals of potential groundwater deficiency in GDEs. The amplitude of groundwater fluctuations, retention and infiltration were determined for vegetation periods characterized by the highest water intake by plants and the highest evapotranspiration. Particular attention has been drawn to the analysis of low groundwater levels in the vegetation periods, with water deficiencies potentially threatening the correct functioning of plant communities in GDEs. Moreover, the study has allowed us to indicate areas with insufficient groundwater levels during vegetation periods that may be hazardous to plant communities. The results may be a basis for the elaboration of correct management plans, protection measures and projects, or GDE renaturalization.

    Opis:
    Protection of water and water-depended ecosystems, in a view of their huge environmental role and high sensitivity to changes of environmental conditions, is one of the fundamental issues included in the legal acts in force, agreements, international conventions, directives and projects. Strong variety of groundwater-depended ecosystems practically causes impossibility to elaborate on an universal methodology for defining their environmental needs. Wetlands are one of the most differentiated groundwater-depended ecosystems, for which the programmes of hydrogeological researches in the range of diagnosis and prognosis of groundwater level changes necessitate an individual adjustment to the study area. Researches of the groundwater-depended ecosystems, including wetlands, mostly in a range of their protection and renaturalisation, require an interdisciplinary approach. On the basis of the researches conducted in the wetland areas in the Kampinos National Park, different hydro-environmental factors determining groundwater level changes in those wetlands were presented. The variety of values and dependences were obtained as a results of the conducted calculations of groundwater levels correlation with different factors. Results of the researches allow to point at the regions, where groundwater levels dependence on precipitation values is significant and the regions, where other factors than infiltration recharge values, have important impact on groundwater table depth. An analysis of trend of changes requires constant update of the monitoring data concerning of groundwater levels in wetland areas. The valorization of vegetation cover and soils done directly (locally) during the field works or on the basis of the papers containing soil characteristic and peatland documentations, requires generalization, adapted to the specificity of the hydrogeological researches in regional scale. Huge spatial differentiation, time-change variation, and secondary transformation processes of the vegetation and soil types, causes, that the results of the vegetation and habitat studies can not be directly used for identification of the factors determining groundwater table level.
