|
|
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 plate / アルミ製金板 |
|
Step 3: |
Description:
|
Species / 樹種名
Species of the targeted trees were recorded.
(ja)

|
|
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 2020, girth at breast height (GBH: 1.3 m above ground) was measured with a steel tape and converted into diameter.
(ja)
2020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(2020年) |
|
Step 5: |
Description:
|
Tree height / 樹高(じゅこう)
In 2020, height was measured with Vertex transponder (0.1 m unit).
(ja)
2020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(2020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:
|
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)。
