Castanea crenata and Diospyros kaki have been cultivated for a long time and main forest crops in Korea. These are distributed nationwide, and commercial cultivations are in the southern part of Korea, except the mountainous sites (highland region). However, due to climate change, the optimal regions of the crop trees are shifting northward. We planted various cultivars of two species in mountainous site to investigate their adoptability for future cultivation. We adopted image and hyperspectral spectrum to monitor their phenological and physiological responses to the environment in the current optimal cultivation (southern region) and experimental site (northern mountainous). The chlorophyll content of both species was higher in the cultivation site than in the mountainous site. On the other hand, the chlorophyll fluorescence of C. crenata in July was higher in the mountainous site than cultivation site. The stomatal conductance showed a large difference by each month and sites due to local weather condition. D. kaki in the mountainous site showed that the leaf area did not increase for each tree even when the stem grew. Also, the increase in vitality of D. kaki in the mountainous site was decreased compared to the cultivation site. It was investigated that D. kaki was more difficult to adapt than C. crenata. On the other hand, ‘Okgwang’ showed the best cultivars of C. crenata in the mountainous sites.
