Premiers impacts anthropiques dans les Pyrénées centrales : approche multiproxy (archéologie, paléoenvironnement)

Abstract : For several years, extensive palaeoenvironmental research was carried out within the whole French Pyrenees, which enabled the construction of a detailed analytical frame to approach the evolution of longterm environmental dynamics and anthropic impacts. In some of the pollen records from core drillings in peat bogs or lakes, indications of stalling of herds at high altitudes were dated around 5800-5600 cal.BC However, the oldest archaeological evidence for the presence of Neolithic groups go back to only 5400-5200 cal.BC Thus, in order to detect traces of human presence attributable either to the Second Mesolithic or to the Early Neolithic, a research program started in 2015. This research consisted of a pedestrian survey campaign in the Troumouse Circus (Gèdre, Hautes-Pyrénées) with systematic test pits, indispensable to assess the presence of archaeological vestiges. If numerous vestiges and historic installations were discovered, the oldest periods remain extremely ephemeral. Only one construction dated to the late Neolithic / early Bronze Age testifies of a steady installation at higher altitudes, which is since under excavation.
