  During the work we examined the vegetation of a wet area near Badacsonytördemic. The grassland has been mowed and grazed intensively by Hungarian grey cattle until 2010, and it was abandoned afterwards. We surveyed three sample areas: the continuously grazed pasture, the mowed grassland and the additional pasture, which was grazed for one month each year.
  Records were made in June 2010 and 2020. We utilized 4×4 m quadrats, and gave the cover of species in percent. Relative nitrogen values (NB), soil moisture values (WB), Social Behaviour Types according to Borhidi, nature conservation values (TVK) according to Simon were also used.
  Based on the results, the vegetation of the area degraded greatly in ten years, its diverse nature disappeared, weeds and invasive species became dominant and species with good foraging value declined. No aggressive competitors were found in 2007, but Solidago gigantea appeared with great cover by 2020. In addition, many weed species appeared, and the ones which were already present in 2010, have increased their cover. Cirsium arvense was a newly appearing weed. Dead biomass also increased greatly.
  To avoid further degradation, we suggest to reintroduce the management to these areas again. To set back weeds and invasive species, regular mowing would be efficient. It would be important to carefully set the date of mowing so that it prevents the spreading of seeds. Mowed plants must be removed from the area as soon as possible.
