The expansion of Calamagrostis villosa in the Giant Mountains - Preliminary results.

Original language description

The expansion of Calamagrostis villosa into Nardo ? Caricion rigidae grasslands has been recorded in the Giant Mountains over the last few decades. The grasslands above the upper tree line were used for cattle grazing and haymaking practices for at least300 years and the expansion of C. villosa has been recorded after the cessation of this management. The response of the C. villosa stands to mowing and nitrogen fertilization was studied in a manipulative experiment over a two-year period. Mowing resulted in the fast decrease of C. villosa coverage, canopy height and biomass production. The fertilization (30 kg N*ha-1 per year) was not able to compensate for the biomass production of mown plots. On the other hand, fertilization resulted in only a slight increase in biomass production in unmown plots. The number of C. villosa shoots decreased rapidly under mowing, was constant under mowing combined with fertilization, and increased in the fertilized plots. The fast negative reaction of
