After a period of 15 years, 17 phytosociological relevés were taken in 2006, on a slope top, on a slope and in a ground lowering area within the soils formed from loam. In 1993 (the first year of fallowing), segetal communities were observed on the slope, on the slope top and in the ground lowering. The slope and the slope top were settled by phytocoenoses of the Aphano-Matricarietum consolidetosum subassociation with a considerable contribution to them of the species of the Sisymbrietalia order. Whereas in the ground lowering, a typical subassociation Aphano-Matricarietum occurred. After 15 years no species characteristic of the subassociation and the association present in 1993 were recorded. In the process of the secondary succession a gramineous community Convolvulo arvensis-Agropyretum repentis appeared. In a part of this syntaxon, mainly on the slope top, a variant with Arrhenatherum elatius, and on the slope a variant with an aggressive species Calamagrostis epigejos were distinguished. In the ground lowering, dominating are the species characteristic of the Ranunculo-Alopecuretum geniculati association: Ranunculus repens, Agrostis stolonifera and Agrostis geniculatus of the Molinio-Arrhenatheretea class. In both communities the species of scrub communities Rosa canina, Crataegus monogyna and forest communities Fraxinus excelsior also occur, however, less frequently. The seeds of the latter species spread anemochorically on the studied area from the adjacent roadside plants. The presence of these species indicates the taking place process of an ecological succession leading towards the formation of scrub communities.
