Abstract:
In Hokkaido University, Tomakomai Experimental Forest, compartment 405, the dynamics of Natural forest were investigated at stand. In 1983, a tree census with an area of 0.5 ha (50 m x 100 m) was established. However in 1992 plot area was devided in two, also in 2001 plot area was changed to 0.24 ha(47 m ×51 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 censuses, there were conducted at 5-year intervals. Besides, compartment 405 has a record of logging in 1956.

Sampling, Processing and Quality Control Methods

Step by Step Procedures
Step 1:
Description:

Location / 位置

The tree census plot is located in compartment 405 of Tomakomai Experimental Forest. The area of the tree census is 0.24 ha(47 m ×51 m)
(ja) 調査地は苫小牧研究林第405林班に位置する。調査区の面積は0.24 ha(47 m ×51 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). After 2001 individual trees were identified using numbered metal plates.
(ja) 胸高直径5cm以上を対象とした。2001年以降、金板を調査木に取り付け個体識別した。

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(1999年以前),コンベックス(2000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。
