Abstract:
To examine ground beetle communities and decomposition functions of cool temperate forests, 1-ha (100×100m) permanent plots were established in 4 natural deciduous broad-leaved forests and 3 coniferous plantations (spruce, fir, larch) in Tomakomai Experimental Forest (TOEF), Hokkaido University. 5 subplots were established in each plot. This study was conducted as a part of Forest & Grassland Survey in Monitoring Sites 1000 Project of the Ministry of the Environment, Japan since 2004. The data is identical to the data available from the Biodiversity Center, Ministry of the Environment.

Sampling, Processing and Quality Control Methods

Step by Step Procedures
Step 1:
Description:

Community Structure, Biomass / 群集構造、バイオマス

Four pitfall traps (aperture diameter 9cm, depth 12cm) were installed in each subplot. Ground animals were collected by opening traps for 72 hours at 4 times every year. Animals were identified (carabid beetles: species, other beetles: family to species, other animals: class to family), oven dried for 3 days at 60 degree Celcius and their weights were measured.
(ja) 各サブプロットに4個のピットフォールトラップ(口径9cm、深さ12cm)を設置した。毎年4回、トラップを72時間開放し、地表徘徊性動物を採集した。動物は同定し(オサムシ科は種、その他の甲虫は種~科、甲虫以外は科~綱まで)、摂氏60度で3日間乾燥させ、重量を測定した。

Step 2:
Description:

Accumulated Mass, C and N Content / 堆積量、C・N濃度

Accumulated organic layer (A0 layer) in forest floor (25cm x 25cm) near each subplot was collected at 1-3 time(s) every year, oven dried for 2 days at 60 degree Celcius and the weight was measured. Carbon and nitrogen contents of these organic layer samples were measured.
(ja) 各サブプロットの周辺で、毎年1~3回、林床(25cm×25cm)の堆積落葉層(A0層)を採取し、摂氏60度で2日間絶乾させ、重量と炭素、窒素濃度を測定した。

Step 3:
Description:

C and N Content / C・N濃度

Surface mineral soil samples (0-5cm depth under A0 layer, 20cm2) near each subplot were collected. Carbon and nitrogen contents of these soil samples were measured.
(ja) 各サブプロットの周辺で、鉱質土壌(A0層下0~5cm、20cm2)を採取し、炭素、窒素濃度を測定した。

Step 4:
Description:

Decomposition Rate / 分解速度

Six (filter no. 1-6) cellulose filters (5cm x 5cm; Benchkote 2300-916, Whatman) were installed into A0 layer (set horizontally at the boundary of A0 and mineral soil) and mineral soil (inserted vertically into surface layer (0-5cm)) in each subplot at 1 or 2 time(s) per year. Two papers were collected from each layer at 3 collecting dates. The ash free dry masses of collected papers were measured and the decomposition rates (mass loss rates) were calculated.
(ja) 年1~2回、各サブプロットにおいて、堆積落葉層(鉱質土壌との境界面に水平に設置)および鉱質土壌層(表層0-5cmに垂直に挿入)に6枚(フィルター番号1~6)ずつのセルロースフィルター(5cm×5cm;ベンチコート2300-916、ワットマン)を埋設した。3回の回収日に、各層から2枚ずつを回収し、灼熱減量を測定して、設置期間中の分解率(重量減少率)を算出した。

Step 5:
Description:

Weather, Coverage of Understory Vegetation, Thickness of Organic Layer / 天候、林床植生の植被率、堆積落葉層の厚さ

Weather, maximum and minimum air temperature and cumulative precipitation during pitfall trapping were recorded. At the same time, coverage of understory ( 0-60cm height from the ground) vegetation and/or thickness of accumulated organic layer were measured within a quadrat (5m x 5m) for each subplot.
(ja) ピットフォールトラップ開放期間中の天候、最低・最高気温、降水量、各サブプロットの林床植生(地上高60cm以下)の植被率(5m×5m方形区、目視)、堆積落葉層の厚さを記録した。
