The Ancient Road once meandered through open heathlands that had emerged since ancient times due to deforestation and the depletion of arable land.
Around 1800, more than a quarter of Jutland was covered by heath. Farmers began to cultivate the sandy soil and plant conifers, especially spruce. Cultivation and forestation has resulted in a loss of 97 percent of heathland in Jutland. Some of the most beautiful heaths in Denmark are located by the Ancient Road and the route also passes many smaller heaths and moors.
