Also the language spoken by forest settlers in Värmland and Norwegian Hedmark of Central Scandinavia belonged to the old Savonian dialects.

This is the influence of Savonian slash-and-burn farmers who colonized the lake section in Southern Ostrobothnia in the 17th century.

The expansion of Savonian slash-and-burn agriculture, which started in the beginning of Modern era, expanded to Central Scandinavia.

The practice of slash and burn agriculture was prohibited in Sweden in the middle of the 17th century and no new Finnish settlers moved to the area.
