Abstract

High-resolution paleoenvironmental data from a peat profile with a small pollen source area are used to reconstruct the impacts oflandnámon vegetation and soils at a Norse farm complex (∅2 at Tasiusaq) comprising two farms in the Eastern Settlement of Greenland. Analyses include the AMS14C dating of plant macrofossil samples and the use of Bayesian radiocarbon calibration to construct improved age–depth models for Norse cultural horizons. The onset of a regionallandnámmay be indicated by the clearance ofBetula pubescenswoodland immediately prior to local settlement. The latter is dated to AD 950–1020 (2σ) and is characterised by possible burning ofBetula glandulosascrub to provide grassland pasture for domestic stock. Clearance and grazing resulted in accelerated levels of soil erosion at a westerly farm. This was followed by an easterly migration of settlement and agriculture. Site constraints prevent an assessment of the demise of the easterly farm, but pressures of overgrazing and land degradation may have been the major factors responsible for the abandonment of the earlier farm.
