Other Site Characteristics

Loess valleys developed in the western region of the Mezofld, running down towards Si-vlgy (the valley of River Si), which borders the site. From the geological aspect, the area belongs to the loess ridges of the plain of Mezofld. In the Pannonic Age, thick marine sediment (sandy, clayey, marly) was deposited and dryed out with the retreat of the sea. In the Lower Pleistocene, as a result of tectonic movements, the united table land was divided in the north-south, northwest-southeast direction and was lifted slightly. The dry surfaces provided excellent conditions for the development of loess, most intensively in the Upper Pleistocene. As for the geomorphology of the region, it is characterised by the series of valleys cut by the water-courses running towards River Si. From the botanical aspect, the region belongs to the Alfld (Great Hungarian Plain). In the evolution of the flora of the area loess played an essential role. The predominant potential habitat of Mezofld is Aceri tatarico-Quercetum and in a smaller proportion loess grasslands as well as steppe woodlands.
