A Voronoi polygon was used to interpret the territories of animals by HASEGAWA and TANEMURA (1981). They suggested a model to form territories of individuals. Each individual tries to move its position from its neighbors as far as possible. Thus individuals might obtain more preferable positions which are the area centers of gravity of the Voronoi polygons. This procedure is repeated until the centers of the polygons become fixed. The model also could be applied to the spatial patterns of trees in a forest. In this case, the times repeated could be regarded as a measure of the stability of the present stand condition. Measurements of six plantation stands of sugi (Cryptomeria japonica D. DON)and four natural stands were calculated. As a result of this application, the times repeated in the sugi stands were less than those in the natural stands, and the planted stands in a wet snowy district had a greater number of repetitions than did the other districts.
