This is the only migrating sand dune left in Denmark. For some 200 years, beginning in the 14th century, this part of Denmark was beseiged by sand storms. It got so bad the State appointed a sand drift commissioner in the early 1800s. He began by planting deciduous trees around his house. Today there are many hundreds of hectares of plantations designed to stop the sand from marching on and covering everything in its wake. But this, in turn, has created more problems. Self-seeding trees are now overtaking the fragile dune heathlands and there's an EU-funded programme in place to chop down as many of these unwanted trees as possible over the coming years.
