Holocene vegetation changes and land-use history in the Andorran Pyrenees since the Early Neolithic: The pollen record of Bose dels Estanyons (2180 m a.s.l., Vall del Madriu, Andorra)

The pollen analysis of a new sedimentary sequence performed at the Bose dels Estanyons peat bog (2180 m a.s.l., Eastern Pyrenees, Andorra) is presented. Seven radiocarbon measurements and complementary macro-charcoal, stomata, and pollen influx analyses are employed to illustrate the dynamics of high-mountain vegetal communities since the end of the Late Glacial period. This high-resolution pollen analysis outlines the evolution of human activities since the Mesolithic-Early Neolithic transition for the first time in this area.
