This study aims to obtain fundamental data for appropriately conserving and managing trees in a buffer greenbelt in Himeji, Hyogo Prefecture (Himeji Ryokuchi, Nakajima District), by investigating the growth characteristics of the trees, which were planted about 30 years ago, based on the data of their heights and diameters at breast-height, which were measured in August 2004, and the calculated aspect ratio values. As a result, the growth of Quercus glauca and Castanopsis cuspida was remarkable, and these species occupied the forest crown. The growth of the subtree layer differed depending on the co-existing species of the high tall layer. With Machilus thunbergii, the aspect ratio usually exceeded 100, showing a declining tendency. On the other hand, with Myrica rubra, the aspect ratio was about 50, showing good growth.
