Megjegyzések:	Grasslands recovered by sowing low diversity seed mixtures of local provenanceare usually managed by mowing. Besides restoration success only a few studies havefocused on the direct effects of post-restoration mowing on recovered grassland vegetation.In this study we followed vegetation changes in 13 successfully recovered grasslands in5 9 5-m-sized sites with continuous and ceased mowing at Hortoba?gy National Park, East-Hungary. We asked the following questions: (i) What are the effects of cessation ofmowing on the vegetation structure and diversity of recovered grasslands? (ii) What are theeffects of cessation of mowing on the abundance of sown grasses, target and undesirablespecies? (iii) Is yearly mowing an appropriate management tool for the maintenance ofrecovered grasslands? Our results showed that the cessation of mowing caused litteraccumulation, while diversity, total vegetation cover and the cover of sown grassesdecreased compared to the mown sites. The cover of undesirable perennial species wassignificantly higher in unmown sites than in mown ones. The species composition of mownsites remained more similar to near-natural grasslands than the unmown ones. Our resultssuggest that without regular post-restoration mowing the favourable status of recoveredgrasslands can rapidly decline due to litter accumulation and by the expansion of undesirablespecies, even in the short-run. We also stress that while yearly mowing is enough tomaintain grasslands recovered by low-diversity seed sowing, it cannot be considered to beenough to recover target vegetation composition.
