Direct evidence of heathland management in the early Bronze Age (14th century b.c.) from the grave-mound Skelhøj in western Denmark

Abstract

Plant macrofossil analysis of soil samples from the grave-mound Skelhoj, western Jutland in Denmark, showed that heather sods had been used as building material. The original vegetation horizon, which was still preserved within the sods allowed the reconstruction of the original vegetation cover of the Bronze Age landscape. It was therefore possible to determine the land-use systems of the Bronze Age societies there during the 14th century b.c. The sods derived from a dry to medium-dry heathland community previously used as pasture. Many grasses and herbs indicate that it was not a very well developed (or old) heathland that was used for the building material of the mound, but a newly re-established heath cover above an older one that had been burnt some years before the sod-cutting activities took place. Charred finds of roots, twig fragments, flowers and seeds of Calluna vulgaris L. (heather) dominated the plant spectrum. Cuscuta epithymum L. (dodder) was found in 31% of the sod samples. This parasitic plant is known for successfully spreading on burnt heather plants that have started to re-develop with new shoots.
