The aim of the present study was to investigate seeds of species that have survived near small mid-forest settlements for about 50 years after they were abandoned. Seed germination was observed on three squares devoid of vegetation established previously on places of former grasslands and yards. On the plots previously covered by perennial ruderal-meadow vegetation of Urtico-Aegopodietum podagrariae association, species characteristic for cultivated and ruderal habitats from Aperion spicae-venti, Polygono-Chenopodion and Sisymbrion officinalis alliances grew from the uncovered soil seed bank. In fields of root crops and gardens, the Veronico-Fumarietum officinalis weed association was well developed. In this phytocoenosis, Fumaria officinalis, Oxalis fontana and Papaver dubium occurred abundantly. Among the species that germinated on these plots were Arabidopsis thaliana, Atriplex prostrata, Erysimum cheiranthoides, Galeopsis tetrahit, Lamium purpureum, Matricaria maritima subsp. inodora, Myosotis arvensis, Polygonum lapathifolium subsp. pallidum and Veronica persica. Despite renaturalization of formerly strongly transformed areas, re-disturbance of plant cover can reveal part of the former synanthropic vegetation.
