The objective of this study was to investigate the site and growth characteristics of Betula costutu growing in the natural stands of Mt. Gariwang and Mt. Joongwang area located in Pyungchang-gun, Kangwon-do. B. costutu was mainly distributed at the rather steep slope and aspect facing from northeast to northwest, and altitudes ranging from 1,000 to 1,200m. It grew on the moist and nutrient rich soils with deep A horizon. Major associated species in the upper stories were Acer pictum, Acer mundshuricum, Quercus mongolica and Cornus controversa. The mean annual height growth of B. costutu distributed at relatively low altitudes of 1,000m was 1.5m. which was the best compared with other altitudes such as between 1,200m and 1,350m. Annual volume growths of B. costutu at the altitudes of 1,000m, 1,200m and 1,350m were 0.021㎥, 0.008㎥ and 0.006㎥, respectively. B. costufu growing at 1,000m also showed better annual volume growth than those at other altitudes(l.200m and 1,350m). B. costata at age of 65 in 1,000m altitude showed the highest total average volume growth of 0.008㎥ while those in 1,200m and 1,350m altitudes were 0.005㎥ and 0.004㎥, respectively.

In order to better understand the role of litter layer on hydrological cycle in forest, we estimated the interception storage capacity of the litter layer at Gwangneung deciduous forest. We first made a thickness map of the litter layer at the study site based on field survey and then collected representative litter samples for the laboratory experiment. We constructed a measurement device consisting of sample tray, drain collector, tipping bucket, and a data logger. Using this device, we examined the relationship between the interception storage capacity (Ci) and the thickness (d) of the litter layer. For the range of d from 25 to 100 mm, there was a simple linear relationship between C(i) and d, which changed with the intensity of the simulated rain. The results were extrapolated to d smaller than 25 mm by considering that no interception occurs without litter layer. Overall, C(i) increased rapidly when d was low (< 25 mm) but the rate of increase decreased as d increased due to clumping. With an average thickness of 59 mm, the estimated C(i) at the site was 0.94 (±0.39) mm. Such an interception storage capacity of the litter layer is comparable to that of the forest canopy, suggesting that the litter layer can play an important role in the forest water cycle.
