Megjegyzések:	Intensification of land use in the last few decades resulted in an increased rate of fragmentation of natural foresthabitats. With decreased patch size but increased total borderline length the influence of the surroundings also increased. Theextent of influence is especially crucial where the forest stands are adjacent to agricultural lands. We studied the vegetation(cover) and seed bank (soil samples, seedling emergence) along adjacent stands of an abandoned vineyard and edge and interiorof an oak forest community (Quercetum petraeae-cerris) widespread in Central-Europe, using five transects (16 m?? plots alongeach transect).We asked the following questions: (i) How do vegetation and seed bank composition differ between the vineyardand forest interior and (ii) which weeds are able to penetrate into the forest herbaceous understorey vegetation and seed banksfrom the vineyard? In total, 15 phanaerophytes and 147 herbs were detected. Negatively associated with canopy shading, herbcover proved the lowest in the forest inferior. Few weeds and other ruderals recorded in vineyard penetrated into the forestinterior. Mean seed density decreased one order of magnitude from the vineyard to the forest interior (from 20,831 to 2,159seed/m??). The seed banks of the abandoned vineyard and edge and forest interior were dominated by ruderals, but decreasingproportion of weeds was detected from the vineyard to the forest interior. Characteristic forest herbs possessed at most sparseseed banks. Our results suggest that high canopy cover mitigates the negative impact of surrounding weedy vegetation on theforest herb layer. Therefore, the effect of surroundings is detectable mostly in the seed banks. We can assume that the formationof an increased ruderal herb cover can be foreseen if canopy opens, because the local propagule sources of forest species aremissing from vegetation and soil seed banks.
