It is important to identify and understand the actual state of the coppice forest called “Satoyama” in Japanese including the tree species, tree height and tree crown in order to manage and utilize it while making the best use of diversified functions of public interest that the Satoyama has. In this study, we selected Tama Forest Science Garden where the forest type close to Satoyama are preserved, we discussed the measuring accuracy and its possibility of spatial measurement of tree height by analyzing the data of airborne laser scanner observed before and after defoliation and attempted to identify the stand structure of deciduous broadleaf trees using the digital surface model (DSM) before and after defoliation. As a result, we were able to measure the ground height within an error of 1 m and the tree top height within an error of 2 m comparing the data of actual measurement. Also, the airborne laser scanner data are found to be effective in identifying the stand structure such as the classification of high tree layer and low tree layer at deciduous broadleaf forest from the change of treetop height before and after defoliation.
