Humans have left their mark upon the park, although they probably never established themselves there in great numbers. Numerous Bronze Age funerary cairns are still visible along the ancient coastline. Later, the forest was mainly used as pasture. Things changed in the middle of the 19th century when the logging industry spread throughout Sweden, affecting almost all the forest of the park. This exploitation ceased, however, at the end of that century, so that the current forest is dominated by trees more than 100 years old. This forest has thus been able to recover a part of its ancestral richness, and so contains an important fauna and flora, with several endangered species, such as the lichen , which is the park's symbol. This geological and biological richness led to the creation of a national park in 1984, followed by the inclusion of the park with the rest of the High Coast in 2000 in the UNESCO World Heritage List.
