Abstract:
We present the pollen analysis of a new sedimentary sequence taken at La Pouretère ( 1720 m), in the mountain vegetation zone of the Marcadau valley (central Pyrenees). The Lateglacial and Holocene chronology is supported by six 14C-dating results. The complementary analysis of some vegetal macroremains, stomata, pollen-clusters and the use of pollen influx allows us to elucidate the dynamic of mountain species such as Pinus and specially Abies but also to infer the unusual part played by Betula at the beginning of the Postglacial period.
