  The most natural and appropriate way to preserve the biodiversity of grasslands is the utilization, which is confirmed by current research. Conservation management requires intensive cooperation between nature conservation and intensive grassland utilization. Therefore, we investigated the effect of extensive grassland utilization on the outskirts of Dejtár.

  Monitoring plots were in Káli and Tapolcai Basin, Balaton Upland National Park, Hungary. We investigated changes in species composition of 2-2 sheep, Hungarian Gray Cattle and horse pastures. The highest number of species was on the pastures of the Hungarian Gray Cattle. 41 species were common in each monitored plots, which are also important dominant species of natural associations and Poaceae species: Agrostis stolonifera, Festuca arundinacea, Deschampsia caespitosa, Lolium perenne, Bromus hordaceus subsp. hordaceus, Poa humilis, Alopecurus pratensis, Elymus repens, Dactylis glomerata, Poa angustifolia.

  The wood-pastures were important elements of the landscape, moreover had apprecieable act in the agriculture. This type of management belongs to the ’agroforestry’ systems which are really ancient agricultural land uses, but nowadays endangered woody habitats in Hungary. The aim of our study was to collect, data about the appearance and traceability of different factors on the vegetation at different parts of a wood pasture.

  Grassland management tests were performed on different grazing loaded gray cattle pasture and hayland areas 4 times (April, May, June, September) during the grazing season in Tapolca-basin. 5-5 pieces of 2×2 m samples were examined on each sample area, prepared according to the Braun-Blanquet method (1964) in April, May, June and September and with this, we also measured the amount of biomass and its content.
  Based on results additional pasture had the largest gazing livestock carrying capacity but it had the weakest feed quality as well. During grazing season due to ongoing livestock grazing, species composition has changed the most in case of pasture and the number of species was the greatest here as well. Proportion of grasses declined in parallel with the amount of legumes, which grown till late summer.
  Nutrient content of pasture forage was the most appropriate because of high crude protein and less crude fiber content. Grazing for 34 days/year was not enough in case of additional pasture where Festuca arundinacea had the largest coverage. This is reflected in low number of species richness and small nutritional values of sample areas. For sedge rich low-lying areas mowing utilization is the most effective.

  The present survey was carried out between 2018 and 2019 in the Tihany Peninsula, on grasslands located south of Belső Lake. These grasslands were being mowed for a few years after a long abandoned period, and had been grazed by grey cattle since 2002. Our main question was the following: during these years, to which extent had the grazing been successful, did the grassland became eventually semi-natural?
