Aspects de l'histoire de la végétation tardiglaciaire et Holocène dans la région des Subcarpates de la Courbure (Subcarpates de Buzau)

A Late Glacial - Holocene sequence from the Bisoca peat bog (Buzăului Subcarpathians) was studied from palynological point of view. The vegetation history, supported by 12 14C dates is described since the end of the Late Glacial. At the onset of the Holocene Ulmus became established by around 9,700 B.P.; Quercus, Fraxinus, Tilia, Corylus became established almost simultaneously by around 9,500 B.P. The local establishment of Carpinus is about 6,200 B.P. Its maximum occurred since 5,000 B.P. Fagus pollen is regularly recorded since 7,000 B.P. Its absolute dominance took place at about 2,000 B.P
