摘　　要：Nowadays, mowing has an increasing role in the management of semi-natural and nature conservation areas. Semi-dry grasslands have been planted on cleared areas of forest in the Pannon Mountains, which would be reclaimed by forest without use of the areas by humans. In our work we analysed cleared grasslands. The questions we tried to answer were which changes were caused by different land use, how favourable mowing can be for the purpose of grassland management and nature protection, do the composition of the plant species and the diversity vary within two years when conditions of precipitation are different. In four sampling areas, in 4 × 10 quadrats we registered the plant species and their cover values. We performed a site assessment in April, June and October, 2013-2014. We analysed the data by using cluster and ordination processes and we compared the sampling areas on the basis of the humidity preference and Shannon＇s index of diversity. According to the results, the composition of species and diversity on the analysed areas used for different purposes considerably deviate from each other. Further, we found a difference between two portions of the area whose had minor deviation in water management.
