Abstract

The analyses of human-environment interactions in prehistoric and medieval mining and metallurgical centres in Europe result in various assessments of the environmental impact of early metal ore mining and metallurgy. In some mining and metallurgical sites or areas, such as the prehistoric basin on the Greek island of Kythnos or the later Morvan and Mont Lozère areas in France as well as Tjursbosjön in Sweden, the impact was significant and lasting. In others, such as: Cors Fochno in Wales, the Falkenstein region in Austria, or the Northern Vosges Mountains in France, the environmental changes were limited and reversible. The results of palaeobotanical research (pollen analysis and analysis of plant macroremains) in peat cores from southern Poland enabled the Holocene vegetation transformations in one of the oldest mining regions in Central Europe to be reconstructed. They also provided new data, used to assess the impact of settlements as well as the development of metallurgy on the environment in the region and changes in bog ecosystems. The first changes in vegetation caused by human activity were observed at the boundary between the Neolithic and Bronze Ages. They are documented by pollen indicating shepherding activity and single grains of cereal pollen. The greatest intensity of change, reflected in sediment as a maximum concentration of charcoal, was recorded at the end of the Bronze Age and attributed to the Lusatian culture. The changes in the vegetation under the impact of human activity until the early Middle Ages were reversible and had a local scope. The intensification of slash-and-burn agriculture was indicated as the most probable and important cause.
