Sugi stands(Cryptomeria japonica D.DON) in Obama district of Fukui Prefecture were severely damaged by unusual snowfall in December 14-15, 1981. In this report, the result of the survey of two severely damaged stands was discussed.
1. Mean height, mean dbh and percentage of damaged trees of two stands are 15.7m, 16.4m ; 20.7cm, 21.2cm ; and 46.3%, 71.5% respectively. 2. The mean diameter of the breaking point of stems, of which value indicates the intensity of snowload accumulated on the tree crowns, is 12.5cm. 3. In general trend, trees which are small in size and high in stem-form coefficient are more susceptible as found in more slightly or moderately damaged cases. 4. The concept of "the extent of snowload" was introduced from the calculated value of total basal area of the breaking point of stems per unit area of stands. |
