Outline of Final Research Achievements

In the Akan-Shiranuka area of Hokkaido, male brown bears with a larger home range size have a higher corn utilization rate than females, and 81% of males use it. Many extermination of bears as a result of invasions into crop fields by bears occurred in the southwestern (peripheral) part of the area. Bears in the northeastern (core) part and the western (surrounding) part are moving into the southwestern (peripheral) part. As a result of continued extermination of bears, the population density of female bears was lower in the southwestern part than the northeastern part of the population. It is necessary to exterminate most of the population in order to reduce the invasion only by extermination, which is not realistic from the viewpoint of population conservation. It is necessary to take non-lethal measures to prevent the bears from becoming problem individuals by implementing control such as installing an electric fence.

Academic Significance and Societal Importance of the Research Achievements

ヒグマの出没や作物への食害に対して行ってきた従来の対症療法としての駆除だけでは農地に出没する問題個体を減らすことができず,また個体群の保全上危機的状況をもたらす可能性が示された。過去30年間にわたり増加を続けている北海道における人とヒグマとの軋轢を軽減していくために,問題個体を生み出さないための出没原因の除去や農地侵入防止など未然防除を併用すること,そのための実行体制として専門人材の配置と実施計画の策定,評価と見直しの仕組みを整えることが重要である。次期管理計画の改定にこれらの仕組みが反映されれば,計画の目標である軋轢の低減と個体群の保全の両立に向けた新しい一歩に繋がると期待される。
