Details of the data are described in: ITÔ,Hiroki; NAKANISHI, Atsushi; TSUYAMA, Ikutaro; SEKI, Takeshi, IIDA, Shigeo; KAWAHARA, Takayuki (2018) Data on forest regeneration after catastrophic windthrow in the headwater region of the Ishikari River, Hokkaido, Japan. Bulletin of FFPRI 17: 265–272 (in Japanese with English summary). Table S1.txt: Tab delimitated text file (UTF-8, LF) containing the temporal changes in vegetation. The structure is as follows: Field name: Description Belt: Numerical identifier of the study belt. Quadrat: Numerical identifier of the quadrat in each belt. Layer: Position in vertical layer (canopy, subcanopy, shrub, herb, vine, moss). Year: Survey year; The survey of Belt [38] in 1988 was conducted in 1989 in real. Date: Survey date; If the month or day was unclear, this filed is described up to the year or month, respectively. Scientific_name: Scientific name of the species. Japanese_name: Japanese name of the species. Cover: Rank of the vegetation coverage (+: 0–0.01, 1: 0.01–0.1, 2: 0.1–0.25, 3: 0.25–0.5, 4: 0.5–0.75, 5: 0.75–1). Table S2: Tab delimitated text file (UTF-8, LF) containing the temporal changes in trees. The structure is as follows: Field name: Description ID: Numerical identifier of the stem. Individual_ID: Numerical identifier of the individual. Belt: Numerical identifier of the survey belt. X: Location along the X axis in the belt (m). Y: Location along the Y axis in the belt (m). Scientific_name: Scientific name of the species. Japanese_name: Japanese name of the species. First: The first year that the stem was observed. Last: The last year that the stem was observed alive; for living stems, the last survey year is assigned to this field. H_1993: Height at 1993 (m); NA for missing data. D_1993: Diameter at breast height in 1993 (cm). H_1998: Height at 1998 (m); NA for missing data. D_1998: Diameter at breast height in 1998 (cm). H_2002: Height at 2002 (m).
