We monitored the partitioning of gross rainfall (Pg) into throughfall (TF), stemflow (SF) and interception loss (Ic) in a 20 m Χ 10 m plot at the 32 years old non-managed plantation of Japanese cypress (Chamaecyparis obtusa) (2,500 trees ha-1) in Fukuoka, Japan. The results showed that Pg, TF and SF were 1757.4 mm, 1018.8 mm (58.0 %), 303.8 mm (17.3 %), respectively, which resulted in Ic of 434.8 mm (24.7 %). Although Ic ratio was comparable to those reported in previous studies in mature Japanese cypress stands (30 data set), SF ratio was the largest. We assumed that TF was diverted to SF when dropping from canopy due to the unpruned dense dead branches in this stand.

This study investigated changes in transpiration and canopy interception loss according to thinning in a Japanese cedar plantation. Transpiration was measured using the sap-flux method. Canopy interception loss was calculated from precipitation, throughfall, and stemflow amounts. Thinning decreased transpiration by 44% and canopy intercepton loss by 43%. Thinning would decrease evapotranspiration and increase water resources.

There is a few observation results of snow interception loss. We observed snow interception loss in a Cryptomeria japonica forest of central Japan for five winters (2008-2013). Cryptomeria japonica is the most dominant species in Japan. Our site is located at the foot of Mt. Hakusan. Maximum snow depths at an open apace near the forest for the four years were 66.9 - 238.7 cm respectively. The ratios of interception to precipitation for three years were 14.2 - 20.8% respectively. The ratio for 2011-2012 was larger than those for the other two years, which would be affected by the thinning. In this forest, thinning was conducted in November, 2011. The ratios of throughfall and interception loss to precipitation for whole the experimental period were 82.6% and 17.4%, respectively. The ratio of interception loss was slightly higher than that except for winter observed in this forest.
