Damage by Brown Bear Ursus arctos to agriculture products in Rikubetsu-cho, eastern Hokkaido, was 69 times for 13 years from 1979 to 1991 based on agriculture damage records of Rikubetsu-cho. Agriculture products damaged were corns, sugar beets, nest boxes of honey bee and cattle. Of them corns and sugar beets were damaged frequently in September and October. Brown bears gave damages nearby the boundary between cultivated field and forest. Sizes of cultivated fields damaged ranged from 0.01 to 1.2 ha with averages of 0.09-0.32 ha for corns and 0.03-0.06 ha for sugar beets. In Rikubetsu-cho 13 bears were killed for 12 years from 1980 to 1992 (10 animals by sport hunting and 3 animals by control hunting).
