Abstract:
In Hokkaido University, Tomakomai Experimental Forest, compartment 124, the dynamics of Natural forest were investigated at stands. In 1986, a tree census area of 0.1 ha (25 m x 40 m) was established. At the 1st time and 2nd time census, we measured Diameter at breast height (DBH) . After the 3rd time, we measured Girth at breast height (GBH) at 5-year intervals (6-year intervals for the 1st and 2nd times, and 3-year intervals for the 2nd and 3rd times) . Besides, There are multiple years of logging records in compartment 124(1934・1935・1936・1937・1984・1985・1991). (ja) 北海道大学苫小牧研究林124林班天然林の動態を調査した。1986年に面積0.1 ha (25 m×40 m)の調査区が設置された。調査間隔は1, 2回目は3年間隔、2, 3回目は6年間隔、3回目以降の調査は5年間隔で実施した。調査項目は2回目までの調査では胸高直径を、3回目以降の調査では胸高周囲長を計測した。また、調査区の立地する124林班では複数年にわたって伐採の履歴が存在する(1934・1935・1936・1937・1984・1985・1991)。

Sampling, Processing and Quality Control Methods

Step by Step Procedures
Step 1:
Description:

Location / 位置

The tree census plot is located in compartment 124 of Tomakomai Experimental Forest. The area of the tree census is 0.1 ha (25 m×40 m).
(ja) 調査地は苫小牧研究林第124林班に位置する。調査区の面積は0.1 ha (25 m×40 m)である。

Step 2:
Description:

Target to measure / 測定対象

The target trees were 5cm or more in diameter at breast height (1.3 m).
(ja) 胸高直径5cm以上を対象とした。

Step 3:
Description:

Species / 樹種名

Species of the targeted trees were recorded
(ja) 測定対象木の樹種を記録した。

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 2000, 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。 2000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。"

Instrument(s): caliper (2 cm unit), steel tape / 輪尺(1980年,1985年),コンベックス(1995年),スチールメジャー(2005年以降)
Step 5:
Description:

Survival / 生枯(せいこ)

Survival or death of the individual was visually measured.
(ja) 測定対象木の生死を確認した。
