West Carpathian Mts. Slovakia R. Janik J. Pichler Institute of Forest Ecology of the Slovak Academy of Sciences Zvolen Slovakia ABSTRACT The paper deals with throughfall and soil percolation in a sub-mountain beech forest situated at the Ecological Experimental Site EES Kremnické vrchy Mts. the West Carpathian Mts. Slovakia . The research was conducted in 1988-2008. The throughfall was sampled at regular periods both from the open plot clear-cut and from the plot with complete stocking covered with a mature beech stand. The soil percolation was evaluated with soil lysimeters. In 1989 and 2004 the plots were treated with cutting - with the aim to reduce the current stocking. The average amount of throughfall was mm in the open plot and mm in the control. The amount of soil percolation decreased with increasing depth from mm to mm in the control and from mm surface through mm 10 cm to mm 25 cm in the open plot. The differences between the plots were statistically highly significant. No significant differences were found between the soil horizons. Keywords throughfall lysimeter sub-mountain beech forest water balance Water as a substantial component of the living environment is a limiting factor for plants animals and humans themselves. The amount of surface and ground water significantly influences both in a positive and negative way the processes of biomass production in individual constituents of all ecosystems and the life itself in this way. At present at the first place commercial aspects of this fact are reaching the top of the agenda. The potential reserves of suitable water are continually decreasing mainly due to negative human activities. Thriftless exploitation of this precious natural resource can result in an enormous effort required for its restoration in the future.
