The Oudsberg nature reserve belongs to a dune belt that used to stretch from Hechtel to Maaseik. 15,000 years ago, after the last ice ages, the Kempen Plateau experienced enormous sand drifts. Deep, empty depressions formed in which fens arose. High sand deposits rose above the landscape like dune ridges. As the climate warmed, birch and oak forests developed. In the Middle Ages, the soil southwest of De Oudsberg became impoverished due to intensive extraction. As a result, only heather could survive. Local overgrazing of sheep again caused sand drift, which shaped the current dune landscape. Today the land dunes are still in full evolution. The Oudsberg was once 95 meters high, but in recent decades it has shrunk by at least 7 meters. More at https://www.natuurenbos.be/natuurbanden/oudsberg

This led to the formation of deep, empty depressions where fens later arose, and high sand deposits that rose above the landscape as dune ridges. The current dune landscape was further shaped in the Middle Ages by local overgrazing of sheep, which caused renewed sand drift.
