Vegetationshistoria de senaste 5000 åren kring Fållnäs gård, Södermanland : med tyngdpunkt på antropogena aktiviteter

Sammanfattning: The manor Fållnäs gård is situated at the northern end of the bay Fållnäsviken, c. 12 km north-west of Nynäshamn, Sweden. A 300 cm long sediment core collected in the bay has been analyzed regarding pollen stratigraphy. AMS 14C dating of terrestrial macrofossils indicates that the sequence covers the last c. 5400 years. The aim has been to study vegetational changes, especially human impact, in the surroundings of Fållnäs gård. Continuous findings of charcoal particles indicate that humans were present in the area at least from c. 3400 BC. Cattle breeding is indicated from c. 2200 BC by almost continues occurrences of Plantago lanceolata. The occurrences of pollen from cereals reveals that humans have been practicing cultivation continuously since the Neolithic/Bronze Age transition, c. 1700 BC, i.e. including a period of c. 1500 years barren of archaeological findings in the area.
