Abstract:
A Larix plantaion forest has been investigated to examine its stand structure and dynamics. A study plot is located in compartment 306 of the Tomakomai Experimental Forest with area 0.10-ha was introduced in 1984, followed by repeated tree censuses (5-10year interval)., 北海道大学苫小牧研究林306林班カラマツの人工林の林分構造および動態を調べるため、1984年に面積0.10haの調査区を設け、5-10年間隔で、本数、胸高直径または胸高周囲長を計測している。更新台帳番号300100号 1924(T13)年 新植 カラマツ 長期観察林59号 1984(S59)年 設定。Hiura, T., Fujito, E., Ishii, T., Naniwa, A., Sugata, S., Ishida, K., Murakami, M., Kato, E., Maeno, H., Fukushima, Y. & Sakai, T.

Description:

Method / 方法

The study plot is located on a flat wetland (280m asl) in compartment 306 of the Tomakomai Experimental Forest.The size of the study plot is 1000m2(25×40m).The methods generally conformed with the literature established by the Forest Research Station, Field Science Center for Northern Biosphere, Hokkaido University. The details and exceptional cases are described below.The census targeted trees with diameter at breast height (dbh 1.3m) equal to or larger than 10-cm in the plot. Trees were identified, and their dbh (or girth at breast height), height were recorded.
