The Tatra National Park is the most visited national park in Slovakia. But the high number of visitors causes structural and compositional changes in vegetation around tourist paths, mountain lakes, mountain chalets and hotels. The impacts of trampling on vegetation and soil are perhaps one of the most extensively studied areas in recreation ecology in many countries. In Slovakia, Prof. Ladislav Šomšák with his team, whom Dr. Ferdinand Kubíček has worked like a considerable member, has carried out the pilot research on trampling in the Tatras (Šomšák et al., 1979a, 1981). The team has studied vegetation changes in mountain, subalpine and alpine zones, in the surroundings of paths, mountain chalet, mountain lake and ski resort. Because observation and detection of changes caused by tourist trampling has ceased, we have carried out an experiment of short-term trampling. The procedure will provide an information on damage of vegetation in response to short-duration trampling. Changes in vegetation cover, vegetation height, bare ground cover, and the cover of individual species can be assessed. The primary objective of this paper is to describe the vegetation response to different levels of trampling. We consider the effect of seasonality to be very important in correlation with trampling. The research presented in this paper records the experimental procedure in the Juncetum trifidi Krajina 1933 association. Experimental study sites were established in the most visited paths traverse, near the Kopské sedlo saddleback. In national parks, the land managers need better information about recreational impacts on the environment to find the optimal balance between natural areas and recreational use. This procedure makes it possible to model the relationship between trampling intensity and vegetation response. The aim of this experiment was to assess the trampling response of the most wide-spread alpine community, the J. trifidi Krajina 1933.
