Variations in pollen proportions of Plantago lanceolata and P. major/media at a Neolithic lake dwelling, Lake Chalain, France

Abstract

Detailed pollen analytical investigations at a Neolithic lake dwelling site on Lake Chalain, Jura, France, show very characteristic variation in the Plantago lanceolata and P. major/media pollen curves in the period during which settlements are recorded (3030–2630 cal. B.C.). At first, P. lanceolata is the more important taxon but P. major/media representation gradually rises, to become the more important taxon in the uppermost settlement phase. After considering the present day ecology and phytosociology of the Plantago species in question, i.e. P. lanceolata, P. major and P. media, and the available archaeozoological and archaeological information, it is suggested that the changes in the representation of these two pollen taxa are the result of a change in the farming economy, at ca. 2800 cal. B.C., which involved a substantial rise in the numbers of domesticated grazing animals and more intensive land use.
