Sustainability Report 2018
Katsunori TAKASE, Associate Professor, Graduate School of Letters
Dr. Takase and his colleagues have been researching sustainable resource use in Hokkaido based on archaeological records such as seeds and animal bones. Their study on plants, fish bones and mammalian bones at 120 sites（150 analysis units） from the Initial Jomon period
to the archaeological Ainu cultural period revealed that, with regard to plants, the use of acorns, grapes （Vitis） and other wild plants, as well as barnyard millets （Echinochloa）, continued for 6,700 years, and that wild plants, salmon （Salmonidae） and Hokkaido sika deer were popular resources that were continuously used.
