In this study, we focused on the reconstruction of the forest vegetation stages in the Sucha valley in the carbonate Belianske Tatry mountains. On the basis of detailed analyzes, direct and indirect gradient analysis of classical typological enrollments sorted into the vertical line, we distinguished the specifics and the definition of differential species at the borderlines of the individual vegetation stages in this area. The influence of the altitude explained 36% of the total explained variability of species data. In the line of typological enrollments led from an altitude of 985, to 1465 m. on the eastern exposition we have identified the 5th, 6th and 7th vegetation stage. In general, within the increase of altitude we have recorded the addition of acidophilic and unpretending species at the expense of eutrophic and nitrophilic species. The specificity of this area is the occurrence of calcitic, glacial and thermophilous species dispersed throughout the vertical line, low sloping of subalpine species, and only a faint floristically defined 7th vegetation stage. The comppsition of the tree schelter in this area (with the incereasing of altitude) heads from nutrient silver fir-beech woods with nitrophilous scree woods with mountain maple, through high-extending silver fir- spruce forests, to narrow belt of acidophylic spruce forests with arolla, dwarf pine and rowan. The silver fir is extending up to the upper boundary of the forest, Typical is the rich shelter of the shrubs, with a stable species, Daphne mezereum and the Lonicera sp. The area is characterized by the extraordinary biodiversity of plant species.
