Abstract:
In Hokkaido University, Uryu Experimental Forest, compartment 109, the dynamics of Japanese larch forest were investigated at the plantation (planted in 1959). In 1989, a tree census with an area of 0.25 ha (50 m x 50 m) was established. After the investigation, thinning was carried out in 1989.The diameter at breast height (DBH), tree height, Height of the crown base, and crown width were measured at 10-year intervals .

Sampling, Processing and Quality Control Methods

Step by Step Procedures
Step 1:
Description:

Location / 位置

The tree census plot is located in compartment 109 of Uryu Experimental Forest. The area of the tree census is 0.25ha (50m x 50m).
(ja) 調査地は雨龍研究林第109林班に位置する。調査区の面積は0.25ha(50m×50m)である。

Step 2:
Description:

Targets to measure / 測定対象

The target trees were 6 cm or more in diameter at breast height (1.3 m). Individual trees were identified using numbered metal plates.
(ja) 胸高直径6cm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 plate / 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)

In 2018, girth at breast height (GBH: 1.3 m above ground) was measured with a steel tape and converted into diameter.
(ja) 2018年調査では、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): steel tape / スチールメジャー(2018年)
Step 5:
Description:

Tree height / 樹高(じゅこう)

In 2018, height was measured with Vertex transponder (0.1 m unit).
(ja) 2018年はバーテックストランスポンダーを用いて0.1m単位で計測した。

Instrument(s): Vertex transponder / バーテックス(2018年)
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:

Crown width / 樹冠幅(じゅかんはば)

In 2009,Crown width of the targeted tree was measured using a tape measure in four directions of 0 degrees, 90 degrees, 180 degrees, and 270 degrees with respect to the reference direction in the plot.
(ja) 2009年の調査では、測定対象木の樹冠幅を巻尺を用いて、調査地内の基準となる方向に対して0度、90度、180度、270度の4方向について計測した。

Instrument(s): tape measure / 巻尺(2009年)
Step 8:
Description:

Grade of wood quality 2 / 樹幹級(じゅかんきゅう)

Grade of tree quality was classified into five categories (after the 'Terasaki'classification) for trees in coniferous forests. Code indications. 1: overstory tree with good wood quality, 2: overstory tree with unstraight stem or with a sign of death, decay, or weakening, or that interrupt a better tree, 3: understory tree, which is expectable to continue vigorous growth, 4: suppressed understory tree, 5: understory tree with unstraight stem or with a sign of death, decay or weakening.
(ja) 「樹幹級」は針葉樹林に適用し、樹木を以下の5つに区分する(寺崎式樹形級区分に準拠)。1:上層の優良木、2:あばれ木、上層の樹冠過弱木・樹冠偏倚木・分岐木・被害木、3:下層木の良木(将来良好な生育が見込まれるもの)、4: 被圧木(ひあつぼく)、5:生育衰退木・倒木・枯損木・傾斜木.
