The aim of the study was to estimate changes in the floristic composition near Švýcárna lodge (1304 m a.s.l.), where cattle grazing after a long-term management cessation was introduced on a pasture area of 3.6 ha in 2012. The pasture was divided into two grazing sub-localities: P1 (Nar) with dominance of Nardus stricta and Avenella flexuosa and P2 (Des) with dominance of Deschampsia cespitosa. For grazing, Highland Cattle was used with a stocking rate up to 1 livestock unit per ha and year. The floristic composition was evaluated and statistically analyzed. After six years of restored grazing the overall species richness enhanced and a higher dominance of rare and endangered species was found. The dominance of some common species like Vaccinium myrtillus, and Calamagrostis villosa tended to decrease within a grazing period in favor of new species colonisation.
