The Foundation for Anthropology and Prehistory in the Netherlands made the journey to and stay in Denmark possible with a grant for the Dutch partners in the excavation at Øster Lem Hede 2001. Thanks are due to KNNV Publishing Zeist, the Netherlands for permission to reproduce fig. 1. I also want to thank Bent Vad Odgaard for sending me his thesis and some articles concerning vegetation development in Jutland. Christine Jefferis is thanked for improving my English, and my colleagues Dr. Jan Albert Bakker and Professor Leendert Louwe Kooijmans for general improvements of the text.
