Abstract

Biostratigraphical studies and radiocarbon datings from 86 sites, mostly ombrotrophic peatbogs, situated within the South-Norwegian spruce forest domai , show that the occupation of the areas by spruce forest was the result of a protracted spread from east, or northeast, to west and south, which started in late pre-Christian time and was completed during the Middle Ages.
