ABSTRACT
New phytosociological studies on permanent study plot (40 ´ 40 m) divided into 16 subplots in the managed forest were conducted in the upper part of basin of Bys-trzanka (Beskid Niski Mts, SE Poland). The aim of the research was to determine the direction of changes in the Rubus hirtus-Abies alba community in the vicinity of the forest where forest management treatments are applied. It was recorded that the total number of species increased from 52 in 2000 to 80 in 2011. The DCA showed sig-nificantchanges in species composition and the cover of species. Among others, the increase of forest edge species (epilobisation) and ruderal species (therophytization) and firstof all the increase of meadow was observed. The structure of the community also changed; the mean cover of shrub species decreased.
