Data on different seed harvesting methods used in grassland restoration on ex-arable land

We present data of the grassland restoration experiment performed in the Bílé Karpaty Mts. (White Carpathians, Czech Republic) in dry species-rich meadows. First we harvested seed material in a preserved source meadow (donor site hereafter) by brush harvesting the vegetation once (B1 hereafter), brush harvesting three times during the season (B3 hereafter), and by cutting green hay (GH hereafter). Then we determined the species composition and seed quantity of the harvested material. Furthermore, we transferred the seeds to an experimental site on ex-arable land (receptor site hereafter), and monitored the development of the meadow communities in the following five years. Data are interpreted in: Á-J. Albert, O. Mudrák, I. Jongepierová, K. Fajmon, I. Frei, M. Ševčíková, J. Klimešová, J. Doležal, Grassland restoration on ex-arable land by transfer of brush-harvested propagules and green hay. Agriculture, Ecosystems & Environment 272 (2019), 74–82.
