[Synopsis] We investigated the distribution of a garden tree, “Round Leaf Holly”, Ilex rotunda Thunberg, dispersed by birds on the Nara Campus of Kinki University. The size height of each tree planted and tree dispersed by birds was measured. We made them to GIS data base, and measured the distance from tree dispersed by birds to the nearest planted tree. The planted trees（ 337.9±57.3cm） were higher average 210cm than the trees（ 127.6±23.2cm） dispersed by birds. We estimated that the distribution region and it was 45.9 ± 1.21m in average. The seed dispersal pattern by birds may determine thus distribution. The possibility of the distribution of the tree to Satoyama area may be low. However when the garden trees will be planted close to Satoyama, it is necessary to examine the influence in detail.
