Abstract
A series of experiments have been continued in order to realize the silvicultural management for the prevention of forest damage caused by the weight of snow crown. This paper deals with the study about the snow crown on the trees of Japanese larch, during the snow season of 1964-1965.
The equipment of experiment is shown in Photo. 1 and 2.
As the result, following points were made clear : The process of snow crown on Japanese larch was similar to that on Japanese cedar, but the crowned state did not continue over a few days. The maximum quantity of snow crown, in the ordinary conditions of snowfall, occurred on the case when the amount of precipitation was about 20 mm.
