In locality called Bátovský Balvan in Biospherical reserve Polana in elevation 600 metres above sea level, we have monitored deep of snow cover, water equivalent of snow cover and density of snow cover. In this report we compare hydrophysical features in 20 years old beech forest and 20 years old spruce forest whit open site. The four years monitoring of snow cover showed that: deep of snow cover was changing seriately: open site - more than beech forest - more than spruce forest. The highest value of snow cover (70 cm) was measuring in winter season 2004/2005 water equivalent of snow cover was the highest (170 mm) on the open site in winter season 2005/2006 the poorest winter for a snow and for a duration of snow cover was winter 2006/2007 at the climax of winter, there is generally the least snow in spruce stand but in an end of winter spruce forest is keeping snow cover longer and retards snow melting the duration of snow cover is seriately spruce forest more than open site more than beech forest. Forest stands in Biospherical reserve CHKO Polana, play a big role in retarding of snow melting and spring runoff from watershed and so contribute to equal hydrological regime.
