Belianske Tatry Mts belong to the richest parts in TANAP from botanical aspect. But complete works about plant communities are very rare in this area: there were studied separated syntaxonomical groups apart, or smaller chosen parts of this mountain separate (Hadač, Šmarda et al., 1960; Hadač et al., 1969). This work applies to the forest communities of the chosen area in the Belianske Tatry Mts. Here is mentioned their phytocoenological review, relations to the chosen ecological factors - light, temperature, soil moisture, continentality, soil nitrates and soil reaction. For better knowledge of the relations and a structure of the studied syntaxons we presented their structural properties - life forms and diversity of vegetation Shannons and Hills index. Exact information gave intensity of the cultural human influence on vegetation (hemeroby) and synanthropicity of vegetation.
