Pollen and diatom analysis of a shore section of the former lake Wervershoof

Abstract

A pollen- and diatom analysis of a shore section of the former Lake Wervershoof was carried out to investigate the history of occupation and vegetation in the region. The section is dated to between 1800 BC and 850 AD; a dating near the end of this period is probable. The presence of human occupation near the lake shore is shown. At this time the lake contained fresh water. The occupation changed its agricultural emphasis from the growing of wheat and barley to the growing of rye. The occupation is ended by a marine transgression. During a break in this transgression there is a renewed inhabitation
