Holocene vegetation change and its correlates in fennoscandia
Climatic and anthropogenic legacy has differently impacted vegetation and its community composition. To determine the extent and origin of changes across Fennoscandia, representative regions were defined that entailed sufficient spatial and temporal data.

Climatic and anthropogenic legacy has differently impacted vegetation and its community composition. To determine the extent and origin of changes across Fennoscandia, representative regions were defined that entailed sufficient spatial and temporal data. Fossil pollen grouped into land cover classes represented Fennoscandian vegetation types, and we focused our analyses and comparisons on woodlands versus anthromes (arable lands and pastures). To determine the correlate(s) of vegetation change, we regressed vegetation types against archaeological (summed probability distributions, representing human impact) and climatic data (mean annual temperature) with Granger causality tests. Additionally, multiple change point analyses were conducted on each single dataset in order to reveal the most significant time points of change. We show that humans have been the strongest correlate to changes in vegetation, especially after the onset of farming, while climate was a strong force in the centuries following the glacial retreat. Indications on the timing of establishment and abandonment of land-use practices such as deforestation in the southern and central regions or of animal husbandry in the North have been found and/or recovered based on the discovered change points.
