Streszczenie:

The paper covers research on groundwater level depth dynamics in unevenaged forest stands of swamp habitats as influenced by meteorological conditions (air temperature and rainfall). The research period comprised hydrological years 2002-2005 with 7 experimental plots examined. The area of investigation was located in Puszcza Zielonka ca 6 km NE of Poznań. It has been found that the highest dynamics of groundwater level depth occurs for the experimental plots of the middle-aged stands, the lowest dynamics of groundwater depth level occurs for the older forest stands (80 to 100 years) and in lesser extent in the youngest forest stands (up to 20 years). However it should be noted that the research data were collected in a short time span, thus the conclusions concerning relations between groundwater level and forest stand age described here should only be considered as a initial thesis requiring further explanation to be proven or rejected in the course of further research.
