Abstract
<p>Tomohiro Nishizono, Kazuo Hosoda, Keiko Fukumoto, Yusuke Yamada, Masayoshi Takahashi, Hideki Saito, Fumiaki Kitahara and Eiji Kodani: Effects of stand condition and history on measurement errors for tree size using terrestrial laser scanning in Chamaecyparis obtusa man-made forests. Jpn. J. For. Plann. 54: 37~44, 2020 Tree size[diameter at breast height(DBH), height, and volume]was measured using terrestrial laser scanning(TLS)on three thinning experimental sites with ten plots of Chamaecyparis obtusa trees. No difference was observed between DBH values measured using TLS and the conventional method. For tree height and volume, TLS values were smaller than that by conventional method. The measured values by TLS for height and volume almost agreed with those by conventional method for small tree, but were smaller than those by conventional method for large tree. Furthermore, the comparison of results of all plots indicates that the absolute value of measurement error for height decreases with increasing slope, and measurement error for height is affected by disturbance history.</p>
