Importance of snow as the meteorological and climatic element was recognized in the past. The snow cover affects the biosphere from global measurement to microscopic population which is related with it. Monitoring of hydro-physical properties of snow cover has a long history in Slovakia but the research of snow microbiology didnt develops so much, Therefore at the present we have a lack of the modern information about microorganisms adapted on life in snow (cryoseston). The qualitative and quantitative occurrence of microbial life in our mountains is unknown. Results this work would answer the questions: Is life present at snow cover? What are the differences in snow cover between forested and unforested ecosystems in Nizke Tatry Mts.? Does altitude influence on the presence of snow microorganisms? We did expedition measurements once a month in winter season at the altitude transect near Chopok in Nizke Tatry Mts. We took samples from the upper layers of snow cover in to the sterile bottles both from forested and unforested area. By microscopic analyzes we confirmed the presence of microbial algae, bacteria and fungi in snow. In our case the altitude doesnt affect the occurrence of microorganisms. We discovered small differences in qualitative presence of bacteria from snow in forested and unforested area. For more information it is necessary to undertake more studies.
