Dynamic of the plant establishment in the experimental seeding into the grasslands restored on the former arable land

Grasslands of White Carpathians belong to the most diverse grasslands of the world, but despite this their large area was plowed in the past. During the last two decades one of the biggest ecological restoration projects in the Central Europe is there ongoing, which aims to restore arable fields back into species rich grasslands. As even a relatively species rich regional seed mixture cannot include the original grassland diversity, grasslands are dependent on spontaneous colonization species after initial sowing. Species, however, face the considerably altered environment, different to preserved reference grasslands. The question is, to what extent can be the colonization of grasslands successful. Eventually, if it is possible to sow them into species poor restored grassland and enforce the formation of a more diverse grassland community. This bachelor thesis experimentally compared establishment (number of individuals during the growing season 2021) of 10 grassland species in sowings on three restored grasslands (old 20 years since restoration) and on three reference grasslands, which were in their proximity and served as reference ecosystem. Sowing was conducted in autumn 2020 into the disturbed and undisturbed microsites 20 × 20 cm. All species successfully established at least in some number..
