The responses of three upland grassland phytocoenoses to three different management treatments were studied in Southern Bohemia. The sites were at an advanced successional stage, with all three being meadows abandoned since World War II: (i) Molinion , (ii) degraded Calthion with dominant Carex brizoides and (iii) plant community with the dominant species Calamagrostis villosa . Three different treatments (cutting, liming and fertilizing) were applied to the three grassland types, and their effects on the diversity, plant cover and biomass production were investigated over a 3‐year period. Analyses showed significant differences between meadow types in time as well as response to treatments. Independent of the treatments, the biomass production and Shannon index increased significantly in all meadows by varying degrees during the investigation period, whereas the cover decreased slightly in the case of the Carex community and the Molinion and remained unchanged in the case of the Calamagrostis community. Changes in the ground cover (as percentage) in response to management treatments varied between the meadow types. Limed and fertilized plots of the Molinion and Calamagrostis communities had higher percentage cover values compared to the control, but the cover of the C. brizoides community was not affected. In contrast, cut plots of the Molinion had slightly reduced cover. The changes in biomass and species diversity showed no significant correlation with the types of treatment used.
