| Outline of Final Research Achievements |
Dense dwarf bamboo would affect negatively on the water relation of survived spruce trees inside the deer-proof fence on Mt Ohdaigahara where the forest had declined due to tree debarking by deer. We estimated the effect of dwarf bamboo removal on the sap flow of spruce trees. Sap flow of spruce were regulated positively by height of tree, debarked ratio, sap area, while removal area of dwarf bamboo seemed not to affect on that.

| Academic Significance and Societal Importance of the Research Achievements |
樹液流速は，これまで報告されてきた気象要因や樹木サイズに加え，過去に受けたシカによる剥皮の影響を受けていることが明らかになった．また，生残木の樹液流速に対するササ刈り払いの規模の影響が示されたため，柵によって樹木を保護するだけでなく，柵によって繁茂したササを刈り取ることが必要である．このことは，今後の大台ヶ原における自然再生推進計画の参考になると期待される．
