Lacina, Jan ; Halas, Petr ; Koutecký, T. ; Šebesta, J. ; Veska, J.
In the years 1968 – 1970 the forest typological survey were carried out in the western half of the Carpathian volcanic mountain range Vihorlat (Slowakia). Differentiation of forests into the units of potential natural vegetation followed geobiocenological school prof. A. Zlatník. During the typological survey 155 geobiocoenological plots were established on which phytocenosis and mostly also soil conditions were studied. In the years 2013 - 2015, thus after 45-47 years, most of these research plots were resampled. Our data showed that current phytocenosis doesn´t indicate habitat change resulting in conversion of potential forest vegetation. In terms of today´s forest management wide using of natural regeneration of deciduous tree species we consider as highly positive. However, some landscape changes, especially adverse succession on abandoned pastures located at the foot of the mountain range could cause impoverishment of biodiversity.
