Landscape dynamics in southern Finland during the Iron Age and the Early Modern Era — Pollen-based landscape reconstruction (LRA), macrofossil and historical data from Western Uusimaa

Research output: Contribution to journalArticleScientificpeer-review

Abstract

In this study, we present a pollen-inferred quantitative reconstruction (LRA) of the past vegetation cover in the southernmost coastal district of Finland on a regional spatial scale using the REVEALS model and on local spatial scales using the LOVE model. The focus of the study spans a period from the Iron Age (500 BC) to modern times (AD 1550). The reconstruction is complemented by historical data and charred plant macrofossils originating from cultivated plants. This information is compiled from published sources. In general, the LRA reconstruction correlates with archaeological evidence, except during the Late Iron Age/Early Middle Ages (ca. AD 1000–1150). The reason for the discrepancy between these two sets of proxy data may be the continuous land use that has affected the preservation and ‘visibility’ of the fragile archaeological evidence from the Iron Age. The strong fluctuation of tree values in the LOVE reconstructions from Lakes Innoonlampi and Tjärnen, both situated in the vicinity of the Early Metal Age cairn complexes, suggest early habitation and anthropogenic activity from ca. 500 BC onwards. According to the LRA reconstruction, small-scale forest clearing, mainly of spruce-dominated forests, associated with simultaneous animal grazing in natural meadows dates to AD 950–1150 and coincides with the Medieval Warm Period.
