Abstract:
In Hokkaido University, Hiyamai Experimental Forest, compartment 9, a natural Beech Secondary forest has been investigated to examine its satand structure and dynamics. A study plot with area 0.5-ha was introduced in 1996, followed by repeated tree censuses (5-year interval). (ja) 北海道大学檜山研究林第9林班ブナ天然林の林分構造と動態を調べるため、1996年に面積0.5haの調査区を設け、5年間隔で、個体の生死、胸高直径、樹高等を計測している.

Sampling, Processing and Quality Control Methods

Step by Step Procedures
Step 1:
Description:

Location / 位置

The study plot is located on a flat wetland (180m asl) in compartment 9 of the Hiyama Experimental Forest. The size of the study plot is 50m × 100m.
(ja) 調査地は檜山研究林第7林班、東~南斜面(標高150-180m)に位置する。調査区の面積は0.50ha(50m×100m)である。

Step 2:
Description:

Targets to measure / 測定対象

The target trees were 10 cm or more in diameter at breast height (1.3 m). Individual trees were identified using numbered metal plates.
(ja) 胸高直径10cm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)

The diameter at breast height (1.3 m above ground level) of the trees to be measured was measured in 0.1 cm increments using a steel tape.
(ja) 測定対象木の胸高直径(地上1.3m)を、コンベックスを用いて0.1cm単位で計測した。

Instrument(s): steel tape / コンベックス
Step 5:
Description:

Tree height / 樹高(じゅこう)

The height of the target trees was measured visually and with a scale pole to the nearest 1.0 m.Since 2013, height was measured with Visuaalinen mittaus (m unit).
(ja) 測定対象木の樹高を目視と測桿(そっかん)ポールを用いて1.0m単位で計測した。2013年以降は目視により1.0m単位で計測した。

Instrument(s): scale pole / 測桿ポール
Step 6:
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 7:
Description:

Height of the crown base / 枝下高(えだしたこう)

In 1996~2001, height of the crown base was measured with a scale pole (m unit). Since 2013, height was measured with Visuaalinen mittaus (m unit).
(ja) 測定対象木の枝下高を測桿(そっかん)ポールを用いて1.0m単位で計測した。2013年以降は目視により1.0m単位で計測した。

Instrument(s): scale pol / 測桿ポール(そっかんぽーる)
Step 8:
Description:

Tree location measurements / 立木位置測定

The short side of the study area was set as the X-axis and the long side as the Y-axis, and the XY coordinates of the trees to be measured were measured in increments of 0.01 m using a tape measure; after 2001, the new boundary trees were measured in increments of 0.01m from the nearest existing standing tree.
(ja) 調査地の短辺をXj軸長辺をY軸に設定し、測定対象木のXY座標を巻き尺を用いて0.01m単位で計測した。2001年以降は新界木について既存の最寄りの立木から0.01m単位で計測した。

Instrument(s): hypsometer / 巻き尺(まきじゃく)
