Only a few percent of the forest areas are covered by individual legally binding agreements with landowners or voluntarily protected (e.g. as part of a certification scheme). A difference in Denmark compared to other Nordic countries is that the concept of the Danish national parks does not automatically restrict any use or does not even protect natural or cultural values. As a consequence, national parks are not included in the statistics over protected nature in Denmark. The national parks in Denmark are more like the UNESCO World Heritage concept in that sense that it does not give a formal protection.
