Investigation of a small peatbog in northern Hungary provides a late Quaternary record of vegetation development effected by climatic changes and anthropogenic disturbances. The aim of this study was to separate climatic signals from the development of a continental eutrophic peatland with the use of plant macrofossil analysis. The development of water catchment is reconstructed using pollen and geochemical analyses. The formation of the lakebed can be traced back to the Late Glacial. A higher water level with oligotrophic conditions can be existed from the Late Glacial to middle Holocene, when the reed beds covered a small area only. This was followed by a hiatus spanning ca. 4400 years, caused by peat cutting during the Imperial Age. The water level decreased and the water quality was more eutrophic. A reed bed evolved around the lake. Terrestrialization started with a bulrush floating mat phase at the close of the Árpádian Age, ca. cal yr AD 1400. The initiation of the Sphagnum-bog underwent similar phases as in the other Hungarian peatbogs. Although remarkable anthropogenic disturbances can be reconstructed in the development of the peatbog, some climatic effects and authogenic processes might be separated by palaeoecological analyses.
