||Many semi-natural grasslands in the whole Europe are in unfavourable conservation status due to succession changes induced by land abandonment. Project aims to test various management treatments in the ecological restoration of semi-dry, mesic and fen grasslands and to set the conditions for their application. It also tries to test new methods for the elimination of expansive grass species in various ecological conditions. It is also focused on the evaluation of changes after a large-scale restoration. Among the project goals there is also monitoring of temporal dynamics and vegetation changes in anthropogenic non-forest habitats to estimate future trends in grassland vegetation. Project is logically related to several past projects focused on grassland vegetation in Slovakia (SK0115, VEGA 0181/09, VEGA 0099/13), when the network of field experiments was established to study relation between management and species composition (vegetation diversity).
