| Definition | Plot code. The third and fourth digits are unique to each site, and the fifth and sixth digits are plot numbers. | Alphanumeric plot code.
An alphanumeric code as [abbreviated site name]-[forest type code][plot number]. For example, TM-DB1 represents the first plot of deciduous broadleaf forest (DB) in the site, Tomakomai (TM). | Site name. | Alphabetical code for forest type:
BC = Broadleaf conifer mixed forest.
DB = Deciduous broadleaf forest.
EB = Evergreen broadleaf forest.
EC = Evergreen coniferous forest. | Forest age classifications (See 2.7.1 and Supporting Information 1.pdf).
S: Secondary.
OS: Old secondary.
OG: Old growth. | WGS84 latitudinal coordinates in decimal degrees (°) to 2 decimal places. | WGS84 longitudinal coordinates in decimal degrees (°) to 2 decimal places. | Elevation above mean sea level (m).
The precision is 5 m. | Plot area (ha).
The precision is 0.01 ha. | Shape of plot. | Mean of mean annual temperature during the period from 1981 to 2010 (°C). | Mean of annual precipitation during the period from 1981 to 2010 (mm).
The precision is 0.1 mm. | Mean of annual maximum snow depth during the period from 1981 to 2010 (cm). |
