Project

Late-glacial and holocene development of the vegetation in the vltavský luh valley, bavarian forest. The dynamics of secular changes (IAA6005603)

pollen analyses of the Šumava Mts. have not been perfomed yet, the reference sites are missing in the European Pollen Network. For to reconstruct landscape dynamics 400 pollen spectra are expected to be analys...
