The paper presents the results of possible regional effects of global climate change on the tree species composition of mountain forest ecosystems. Our model area has been represented by the valleys: Vajskova and Lomnista in Low Tatras Mts region. The suitability of the current and future changed climatic conditions for particular species has been assessed by means of the analysis of the bioclimatic area of each examined tree species. The analysis has been done for the tree species as follows: Norway spruce (Picea abies), silver fir (Abies alba), European beech (Fagus sylvatica), mountain pine (Pinus mugo), sycamore maple (Acer pseudoplatanus), European ash (Fraxinus excelsior), European larch (Larix decidua), mountain ash (Sorbus aucuparia) and cembra pine (Pinus cembra). The results hint at the possibility of considerable changes in the tree composition of mountain forests in the future. The climatic changes will probably have a negative impact primarily on silver fir, Norway spruce and mountain pine - important commercial and stand building species, The effects of the climatic changes are also expected on other species.
