Popis: International audience; Using an interdisciplinary methodology based on pedoanthracology, palynology and sedimentary charcoals,landscape transformation in the Pyrenees mountains during the Holocene is analyzed, with specialattention to altitudinal variation in the treeline. The data sources were eight soil profiles on a transect at2000e2600 m a.s.l. and a sedimentary record extracted from a very nearby peat bog at 2247 m a.s.l.The combination of three different proxies permits a more viable and qualitatively complementarydata set, making it possible to better interpret the vegetation dynamic in this space through theHolocene.Analysis of the data showed that the Pyrenees landscape has undergone important changes during thisperiod. The changing treeline is a good example. There is evidence of the decisive role of fire in theconfiguration of this landscape.Finally, this study shows that herding and agricultural uses over thousands of years in the study areahave had a determining influence on the current configuration of the territory, equal to or moreimportant than climatic factors.
