added by archaeologs A Danish word meaning 'land taking', used to describe a common form of early agriculture in which an area of woodland was cleared and cultivated (which has been identified in the pollen record). The land was later abandoned and was taken over by weeds, finally reverting to woodland. Its regeneration began with the birch, a rapid colonizer of areas cleared by fire. Landnam has been recognized in pollen analysis by changes in the pollen spectra: the drop in tree pollen, the appearance of grass and plantain pollens, a subsequent increase in the latter, and an eventual reappearance of the tree pollen. Landnam range in date from Neolithic to Bronze Age.
