Abstract
We investigated seasonal photosynthetic capacity and water use efficiency changes of Korean fir (Abies koreana Wils.) trees located at three sites around the peak of Mt. Halla, Witseorum, Youngsil and Jindallebat. At each sites, we chose healthy and declining individuals to examine the differences of physiological characteristics between them. Net photosynthetic capacity in $15^{\circ}C$ were lower than those of $20^{\circ}C$ and $25^{\circ}C$. The difference of net photosynthetic capacity between healthy and damaged trees was clear in June and August but damaged trees recovered with passing of the time. There was no difference between healthy and damaged trees in September on photosynthetic rate. Generally, water use efficiency (WUE) of damaged trees was higher than healthy trees.
