Data researched from June to August 2017 by setting up pitfall traps on the eastern and southern slopes of Mountain Irumukeppu in Hokkaido and within the Sorachi Forest Management Area in Hokkaido. Alphabets of “Trap No.” indicate the abbreviated treatment, the first number indicates the site number, and the last number indicates the trap number in the site. The detail of treatment, the area, the year of harvest, the tree density, the trunk basal area of breast height, the vegetation ground cover, the numbers of traps set, and the trapping period in each site and the detail of trapping method are shown in the text (in Japanese). An English paper using the same trap is also available (
