Summary:

Natural and anthropological climate changes are due to reason why unfavorable water resources are changed. The Forest Promotion Complexes are a functional areas in peculiarities about to ecological meaning, educational and social. The area of the FPC Lasy Rychtalskie have high retention potential. Surface outflow is relatively low ca 4% of annual precipitation and occurs in the winter half-year extending into May. The prognosis of groundwater level changes expressed by groundwater level dynamics was created on the basis of negative annual rainfall trend. The projection was calculated on assumption that significant changes in forest swamp ecosystems would occur provided that average groundwater depth level decrease by 50% of the actual groundwater level depth. The reduction of groundwater level depth as the outcome of this scenario can be expected in 100-year period. Pragmatic action to be taken should prevent from the outflow of the water from the areas. The earlier carried earlier out chemical tests did not reveal any excessive accumulation of chemical pollutants in soils, as well as surface and groundwater.
