Spontaneous restoration of wetlands on arable field was observed in the part of South Bohemia. The main aim of the study was to describe colonization of the newly formed wetlands by plants in relation to character of the site and its surroundings (age and size of the wetland, distance to the field margin and to a nearest permanent wetland). Data were collected during six seasons (2011, 2012, 2013, 2014, 2015, 2016) and analyzed using regression analyses, scatterplots and ordination analyses (DCA, CCA). There were found no significant effects of the distance to the permanent wetland and the distance to the edge of the field on species composition of the newly created wetlands. The effect of successional age of wetlands on their species composition was significant. Species with a higher colonization ability were relatively more frequent in those wetlands located in a longer distance form the edge of the field. Participation anemochorious and hydrochorious species increased during a succesional time on studied wetlands, the proportion zoochorious and hemerochorious species decreased. These conclusions, however, be taken with caution, because it captured with a relatively small margin successional age. In general, it was shown that spontaneous restoration of wetlands on arable land is possible and runs to (semi)natural wetland vegetation.
