in the forest areas of Central Sweden. The Forest Finns had moved from Savonia in Eastern Finland to Dalarna, Bergslagen and other provinces in central Sweden during the late-16th to mid-17th century. Their relocation had started as part of an effort by Swedish King Gustav Vasa to expand agriculture to these uninhabited parts of the country. The Finns in Savonia traditionally farmed with a slash-and-burn method which was better suited to pioneering agriculture in vast forest areas. This was also the farming method used by the American Indians of Delaware.
