Utrechtse Heuvelrug National Park occupation. Intensive land use, reforestation and the building of country estates transformed the appearance of the Utrechtse Heuvelrug over the centuries. The history of the region is reflected in the wide variety of soil types, relief and land use. The Utrechtse Heuvelrug is the second largest forest area in the Netherlands. In the forest some relics from the original post-glacial forests can be found, including oak and beech. In the park several marten species can be found, such as the European badger ("Meles meles") and the European pine marten ("Martes martes"). There are more than 100 bird species living in
Meles (genus) has been much discussion as to whether it is a single species or three distinct species. There are geographical differences between individuals from different parts of the range in skull structure, morphology of the first premolar teeth, and facial markings. Some authorities advocated placing European and Asian badgers in separate species, "Meles meles" and "Meles leptorhynchus" (Milne-Edwards, 1867), the boundary between the two being the Volga River. Others considered there to be three subspecies, "M. m. meles", found west of the Volga, "M. m. arenarius-leptorhynchus", found between the Volga and Transbaikalia, and "M. m. amurensis-anakuma" from the Amur region and
