Abstract: |
In Hokkaido University, Tomakomai Experimental Forest, compartment 335, the dynamics of Natural forest were investigated at stands. In 1991, a tree census with an area of 0.20 ha (40 m x 50 m) was established. At the 1st census, we measured Diameter at breast height (DBH). After the 2nd time, we measured Girth at breast height (GBH). The census interval was 10-years between the 1st and 2nd census. After the 2nd census, census were conducted at 5-year intervals. Besides, There are multiple years of logging records in compartment 335(1956, 1972, 1989, 1990).

Step 2: |
Description:
|
Target to measure / 測定対象
The target trees were 5 cm or more in diameter at breast height (1.3 m). Individual trees were identified using numbered metal plates.
(ja)

|
|
Step 4: |
Description:
|
Girth at breast height, Diameter at breast height / 胸高周囲長(きょうこうしゅういちょう),胸高直径(きょうこうちょっけい)
Before 1999, diameter at breast height (DBH: 1.3 m above ground) was measured with a caliper (2 cm unit). Since 1999, girth at breast height (GBH: 1.3 m above ground) was measured with a steel tape and converted into diameter.
(ja)
"1999年以前の調査では、測定対象木の胸高直径(地上1.3m)を、輪尺(りんじゃく)を用いて1cm括約で計測した。
1999年調査から、胸高周囲長(地上1.3mで測定)をスチールメジャーを用いて計測し、その値を胸高直径に換算した。"
