Abstract:
In Hokkaido University, Tomakomai Experimental Forest, compartment 423, the dynamics of Natural forest were investigated at stand. In 1983, a tree census with an area of 0.50 ha (50 m x 100 m) was established. However in 1992 prot area was changed to 0.25 ha (50 m x 50 m). 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).The census interval were 9-years for the 1st-3rd census, and 4-years between the 3rd and 4th census. After the 4th censuss, census were conducted at 5-year intervals. Besides, There are multiple years of logging records in compartment 423(1955・1959・1967・1969・1970・1982・1987). (ja) "北海道大学苫小牧研究林423林班天然林の動態を調査した。1983年に面積0.50 ha (50 m×100 m)の調査区を設けたが、1992年に0.25 ha(50 m ×50 m)に変更した。調査間隔は1-3回目は9年間隔、3, 4回目は4年間隔、4回目以降は5年間隔で調査を実施した。調査項目は1, 2回目は胸高直径を、3回目調査以降では胸高周囲長を計測した。また、調査区の立地する423林班では複数年にわたって伐採の履歴が存在する(1955・1959・1967・1969・1970・1982・1987)。 "

Step by Step Procedures
Step 1:
Description:

Location / 位置

The tree census plot is located in compartment 423 of Tomakomai Experimental Forest. The area of the tree census is 0.25 ha(50 m ×50 m).
(ja) 調査地は苫小牧研究林第423林班に位置する。調査区の面積は0.25 ha(50 m ×50 m)である。

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) 胸高直径5cm以上を対象とした。金板を調査木に取り付け個体識別した。

Instrument(s): metal plates / アルミ製金板
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 1999, girth at breast height (GBH: 1.3 m above ground) was measured with a steel tape and converted into diameter.
(ja) "1998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。"

Instrument(s): caliper (2 cm unit), steel tape / 輪尺(1998年以前),コンベックス(1999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。

Step 6:
Description:

Shortage of wood / 欠点(けってん)

Shortage of wood of the targeted trees was measured. Description of wood damage: broken, fallen, fungal-damaged, insect-damaged, frost crack, bent, bifurcated, unavailable (as timber).
(ja) 測定対象木を木材として利用した場合の欠点を記録した。記載内容:折れ、倒れ、菌害木(きんがいぼく)、虫害木(ちゅうがいぼく)、凍裂木(とうれつぼく)、曲がり、二叉(ふたまた)、採材不能(さいざいふのう。木材として使用不可能)。
