  During the survey, the vegetation, botanical composition and grassland management values of a grassland were studied. The study site was originally a pasture, then was transformed into an arable land and finally back to pasture. The 160-ha-sized area is called „Szűzföld” and is located in the Zámoly Basin, West Hungary. In 1998, grazing of Hungarian grey cattle has begun on the grassland. The changes in the vegetation were followed from 1998, making records in every 6th year (1998, 2015, 2021). 6 coenological records were made in each type of grasslands, by recording the list of the occurring taxa and their cover values. During the survey the main questions were the following: considering nature conservation, coenology and grassland management, in which direction does the vegetation evolve with the grazing? Was the grazing with Hungarian grey cattle successful?
  Based on the results, the grasslands became much more mosaic-like; drier and wetter vegetation patches could be separated (2015, 2021). As the grazing continued, species richness and diversity increased, especially in the wet areas.
  The number and the cover of economically important grass taxa and legumes have increased. The following taxa became dominant: Festuca pseudovina in the drier parts, Agrostis tenuis and A. stolonifera in the wet ones. Based on the life form system of Pignatti, the area is not overgrazed, as rosette and reptant taxa did not became dominant. Based on nature conservation values, cover of the taxa of natural grasslands increased.
  During the grazing, the meadow was universally covered mainly by weeds in 1998, and became much more valuable by 23 years later by means of nature conversation and grassland management. Moreover, this state has been stabilized according to the diversity values.
  Based on the results, the grazing with Hungarian grey cattle was successful by both nature conservational and economical means.
