Vegetation history and landscape management from 6500 to 1500 cal. b.p . at Lac d’Antre, Gallo-Roman sanctuary of Villards d’Héria, Jura, France

摘要: The lake sediment record was used to reconstruct past vegetation dynamics and human impacts from the middle Neolithic (6500 cal. b.p.) Middle Ages (1500 around Lac d’Antre in southern Jura mountains of France. This surrounded by Gallo-Roman sanctuary Villards d’Heria, which has been widely investigated archaeologists enables a comparison between palaeoenvironmental proxies archaeological data. Pollen microscopic charcoal analyses were conducted on 500 cm core with eleven radiocarbon dates providing chronological control. In mixed oak woodland context, successive development Taxus, Fagus Abies mainly caused climatic variations during Neolithic, there weak impact. first significant signs activity detected Bronze Age 3900 b.p., followed an increase pressure clearances Iron Age, 2700 b.p. occupation continuous occupation. All analysed data indicate that strongest impact occurred period, matches d’Heria previously dated 2000 1700 1st 3rd century a.d. Moreover, appears have new period settlement close at beginning Ages. low accumulation rate (CHAR) recorded suggests fire not main agent clear dense woods create cultivated fields pastures. High CHAR values Roman may represent use for domestic agro-pastoral activities.
