Description	Calamagrostis villosa has recently expanded in Nardus stricta-dominated sub-alpine grassland of the Giant Mountains (Krkonoše/Karkonosze, the Czech Republic). To investigate whether this expansion has been promoted by high nitrogen deposition or by the cessation of agricultural management, grassland plots dominated by C. villosa were manipulated with four treatments: control (Con), fertilised (Fer), cut (Cut) and cut-fertilised (Cut-Fer). NH4NO3 was used at the rate of 30kg N ha-1 and fertilisation and cutting were performed once a year after data collection in late July between 2000 and 2006. Plant species composition (analysed by RDA) was significantly influenced by cutting but not by fertilisation. Cutting reduced the cover, biomass, sward height and tiller density of C. villosa. Seedlings of N. stricta and panicles of C. villosa were recorded only in plots with cutting management. To investigate the effect of treatments on the spread of C. villosa, grassland sods dominated by N. stricta were tran Calamagrostis villosa has recently expanded in Nardus stricta-dominated sub-alpine grassland of the Giant Mountains (Krkonoše/Karkonosze, the Czech Republic).
