| Outline of Final Research Achievements |
This study aimed to investigate Liberian western chimpanzees' distribution, ecological features, and behavioral characteristics in their stone tool-using. Although western chimpanzees are critically endangered, the conservation measurements are quite insufficient. Chimpanzees range in non-protected forest. They also cross national border between Liberia and Guinea. Special site is Kpala Village. People in Kpara village regards chimpanzees as sacred. Chimpanzees coexist with people in the community forest. To establish the sustainable system for study and conservation, we promoted cross-border collaboration and communication; we set field research and meetings at which Liberian and Guinean researchers, local people, and political authorities worked together. It will contribute to the further development of local initiatives.

| Academic Significance and Societal Importance of the Research Achievements |
本研究はヒトに最も近縁なチンパンジーの研究と保全に貢献する。とくに西アフリカのチンパンジーは石器使用にあげられるユニークな文化的行動をもち、ヒトとの比較研究に欠くことのできない存在だ。しかし、その保全状況は脆弱で、リベリアでは内戦の影響から、基本的な生息状況の把握も遅れている状況だった。リベリアのパラでは新しい道具使用レパートリーを発見した。パラではギニアの長期調査地ボッソウと同様に、住民がチンパンジーを守る文化を持っていた。住民・研究者・行政の関係構築、さらには国際機関との協力関係をつくった。
