| Outline of Final Research Achievements |
Allium bidentatum was most frequently eaten after one hour from the start of grazing. After a while, they began to eat Artemisia frigida (Asteraceae), but did not eat Stipa krylovii (Poaceae) even though it was a dominant species. Goats ate plants with roots was not observed that and the above ground biomass consumed by goats was about 0.9 times that of sheep.

過放牧は砂漠化の主要因と言われながらもその内容はあいまいな部分が多く存在する．過放牧による影響を明らかにするには放牧中の家畜の行動を明らかにしなければならない．しかしながら，ヒツジやヤギは警戒心が高く，行動を直接観察することが難しいため，過放牧の評価に必要な，いつ，何を，どのくらい採食したのかという要素が記録できない．この問題を解決するため，家畜にカメラを取り付けて詳細な行動を記録し，過放牧によって生じる草原劣化のプロセスについて明らかにする．
