Labe Lowland is situated in the Central Bohemia. Flat landscape thanks to its rich nutrient soils has a long history of human occupation. Since the first neolitics Polabí has belonged to a traditional agricultural region. Late Glacial palaeoecological record is stored in many paleomeanders of the river Labe or lake(s) as Hrabanovská černava. Many of these sites were silted up and several of them converted to arable. The pollen history was investigated already in the first half of the 20. century and we keep studing it until now, e.g. project IAAX00020701 http://botany.natur.cuni.cz/paleo/?id=c_bohemia.
