| Outline of Final Research Achievements |
The Chugoku Mountains, western Japan is known as iron production area since seventh century. To elucidate impacts of ancient manufacture on vegetation, sediment samples from two sites in the Chugoku Mountains, were analyzed for pollen and charcoal. Pollen records suggest that secondary forest dominated by deciduous oaks with Cryptomeria japonica had been developed at ca. 2000 cal yr BP. In the medieval period, Pinus, Poaceae and Artemisia pollen increased coincidentally with increase of charcoal particles. It suggests that open landscape was established by fire disturbance. Many iron-smelting sites from sixth to eighteenth century were excavated in the Chugoku Mountains. Based on comparing pollen and charcoal records with archaeological and historical records, it is suggested that decrease of forest resource at two sites were caused by iron working, which consume a large amount of wood.
