Four methods of grassland restoration on arable land using species-rich seed material harvested directly in the source Bromion meadows (Vojšické louky, Bílé Karpaty protected landscape area (PLA), Czech Republic) were compared. Species composition of established grasslands was evaluated through the vegetation development. The restoration methods comprised of i) green hay application, ii) sowing of seed mixture obtained from brush harvester collecting once in the vegetation period, c) sowing of seed mixture obtained from brush harvester collecting three times during the vegetation period per site and d) spontaneous succession were compared. The experimental plots were established in the surroundings of Malá Vrbka (Bílé Karpaty PLA) in 2009. Species composition and vegetation cover were recorded in 16 m2 plots in spring and autumn of 2010 and 2011. Altogether 144 releves were statistically analysed using direct (CCA) and indirect (PCA) gradient analysis; cluster analysis (Statistica for Windows), and Simpson, Jaccard and Sorrensen similarity coefficients. Species composition was significantly affected by the plot establishment period which explained 49.6% of variability in the species data set. Species composition was also affected by used restoration method. However, the restoration method had no significant effect on the plant species richness.
