Charakteristika: 

Many wetland habitats around the world have been degraded or lost due to landuse conversion for agricultural purposes, management intensification or abandonment. Restoration of wetlands is a means to bring back the ecological functions of wetlands, and the goods and services they provide, as well as improving existing but degraded wetland habitats. Wet grasslands, as human-created habitats, are vulnerable to any change in management practices, which can greatly influence plant species composition. In the Czech Republic, the traditional management practice was for the wet grassland to be mown 2-3 times each year. On drier sites, this led to the formation of wet grasslands dominated by Molinia caerulea, but which had high plant species diversity. However, a more extensive management regime of only one cut per year was introduced in some of these meadows, which has resulted in the introduction of hemicryptophyte species and the reduction in plant diversity.

Cíle práce: 

The aim of this project is to determine whether a return to a more traditional management regime of three cuts per year will restore the higher diverse Molinia-dominated wet grasslands.

Materiál a metody: 
  • cutting treatments (control = 1 cut / year; experimental = 3 cuts / year) in selected plots using a mechanical cutter

  • estimation of plant species cover

  • determining aboveground production, biomass and nutrient contents in harvested plant material
