Vegetation dynamics and human activity in the Western Pyrenean Region during the Holocene

Abstract : The present paper summarises the evolution of the vegetation and the evidences of anthropisation in the Western Pyrenees (Northern Iberian Peninsula) during the Holocene. All the palynological studies published about this region, about both natural and archaeological deposits, have been compiled, and special attention is paid on the available radiocarbon dates. We also present new results of the paly-nological study of the peat bog of Atxuri (Navarre). The main results document the arboreal colonisation in the early Holocene; the first evidences of anthropisation associated with the Early Neolithic (ca. 5500 e4500 cal BC); the consolidation of a productive economy (agriculture and pastoralism) in the Middle/ Late Neolithic (ca. 4500e3200 cal BC) and above all in the Chalcolithic (ca. 3200e2200 cal BC); and the rise of complex urban societies in the Bronze Age (ca. 2200e900 cal BC) and Iron Age (ca. 900 e200 cal BC) and their impact on the vegetation.
