Abstract:
In Hokkaido University, Wakayama Experimental Forest, compartment 9, the structure and the dynamics of the natural forest were investigated. In 1991, a tree census with an area of 0.5 ha (100 m x 50 m) was established. The diameter at breast height (1.2m) and tree height were measured at 5-year intervals (10-year intervals for the 4th times).
