Description :
Based on geophysical prospection, a distinction has been made between the underlying aeolian sand sheet, the dune cores, and younger aeolian accumulation bodies, and they have been sedimentologically characterised. The dune sands have been dated by OSL, macro-remains and the humous material of fossilised soil horizons by the radiocarbon method. Forest clearing of much of the landscape began during the Neolithic period. Two significant phases of sand dune growth have been dated to the Bronze Age and the High Middle Ages, largely determining the aspect of the present dune landscape. There is evidence of younger remobilisation phases up to the 1950s. With reduced settlement pressure, each time the dune landscape returned to a phase of morphodynamic stability. Today, under the name of Dürnbucher Forest, the Abensberg/Siegenburg dune landscape is one of the largest contiguous forest areas of Bavaria.
