A late Würmian and Holocene pollen profile from Tüttensee near Chiemsee, Bavaria, covering 14 millennia of vegetation history, shows the late Würmian reforestation of the area, Holocene woodland development, and later the human impact on the landscape. In the early Holocene a distinct Ulmus phase preceded the Corylus and Quercus expansion. Afterwards, between 6000 and 4000 BCE, Picea was most common. The expansion of Fagus and Abies started at 4000 BCE, together with the decline of Ulmus . Fagus was more common than Abies . From 500 BCE Abies started to decline, Fagus has also declined from 1000 CE onwards. Before the modern times Picea / Pinus phase Quercus is prevailing. The prehistoric human impact is rather weak. A short reforestation phase at ~ 1 BCE – 1 CE hints at the rather complex migration history in this region with so called Celts, Germanic people and Romans involved. Strong human impact indicated by cereals, Plantago lanceolata , other human indicators and deforestation started at 900 CE. |
