Investigations were carried out in wet – next to Tatárszentgyörgy, and dry grass pasture – next to Bugac, both located in Kiskunság, in the central region of Carpathian Basin. Recordings were taken every June of 2007, 2008, 2009 and 2010 from Tatárszentgyörgy – where cattle were grazed, and 1997, 2005 and 2010 from Bugac, where cattle and sheep were grazed. Coenological recordings were taken in three zones. The first zone ("A" zone) located 0-50 m near the stable, second zone ("B" zone) located 50-150 m from the stable, while the third zone ("C" zone) located farther then 150m from the stable. Analyses of ecological and environmental factors were based on Borhidi’s relative ecological indicators. Life form analyses were performed by Pignatti life form types. For statistical evaluation, R software was applied. Shannon diversity. Based on our results for both dry and wet grasslands, quadrates of "A" zone were well isolated from the rest of the zones. Overgrazing, which involves considerable trampling, vanishes differences among vegetations, thereby promotes weed and disturbance tolerant rich vegetation. The lowest species number and diversity could be found here. Recordings for "B" and "C" zones separated from recordings of "A" zone, furthermore, quadrates of wet and dry grasslands formed separate groups. From recordings of "B" and "C", zone perennial grass species (H caesp) and the emerging perennial (H wrap) species multiplied and these species were the indicators of grazing. The greatest lifeform richment were presented among "B" zone recordings. The amount of intensive grazing indicator species, such as creeping perennials (Hrep) was significant in "B" zone recordings of Tatárszentgyörgy. Grazing stabilised the local vegetation, but increased the ratio of disturbance tolerant species, which was confirmed by conservation evaluation. This is due to the conversion of grassland types, the transition from free grazing to switch grazing, which resulted in an intensive involvement of the more distant "C" zone as well. "A" zones fully converted; they changed into fully reliefs. Further located sample area vegetations were not homogenised by grazing and even helped the preservation of characteristic species. In the aspect of environmental protection, vigorous grazing led to a more valuable vegetation in "B" zone in an arid grassland (Bugac). According to the sample area, wet grasslands from the sandy areas of Kiskunság, preserve nature protection values and grass composition better moving away from stables, due to less grazing pressure. Drier backgrounds tolerate stronger grazing pressure (Bugac), while in case of wetter areas (Tatárszentgyörgy) – considering sustainability – grazing should be carried out with caution.
