A pollen-based reconstruction of the paleoenvironment and cultural landscape in Southeastern Norway from the Iron Age to the Middle Ages

Human activities have impacted the natural landscape and vegetation from the emergence of agriculture onwards. Subsequent traces of anthropogenic activities are documented and preserved in paleoenvironmental archives, such as peat or lake sequences. The current study utilizes a high-resolution pollen dataset retrieved from a peat sequence in combination with archaeological data from the area to reconstruct the paleoenvironment and cultural landscape of the area of Haraldstadmyr bog in Southeastern Norway. An in-depth analysis of agricultural activities was performed focusing on the period of the Early Iron Age to the Medieval Period. Utilizing radiocarbon dating, a chronology of farming activities was provided. Archaeological burial dates from a local burial site located were used in comparison with the pollen data to interpret habitational patterns of the local area. As a result, periods of intensive farming as well as periods of abandonment were identified.

The current study utilizes a high-resolution pollen dataset retrieved from a peat sequence in combination with archaeological data from the area to reconstruct the paleoenvironment and cultural landscape of the area of Haraldstadmyr bog in Southeastern Norway. An in-depth analysis of agricultural activities was performed focusing on the period of the Early Iron Age to the Medieval Period. Utilizing radiocarbon dating, a chronology of farming activities was provided. Archaeological burial dates from a local burial site located were used in comparison with the pollen data to interpret habitational patterns of the local area. As a result, periods of intensive farming as well as periods of abandonment were identified. In addition, periods of pastoral farming were distinguished from periods of mixed farming. The forcing factors of the changes seen in farming strategies and agricultural intensity are likely related to climate changes as well as societal changes in the area. In this study, a new finding is proposed, indicating an abandonment of the area around 950 CE. An abandonment of the agricultural area in Southeastern Norway in the mid 10th century has not been previously discovered nor studied. Further in-depth studies are needed in order to confirm this finding, as well as to identify the forcing factors of the abandonment.Show less
