Topic (target variable):
basal area
(156)
i
Sum of the stem cross-sectional areas at a height of 1.3 m (level for measuring diameter at breast height [dbh]) of living trees and shrubs (standing and lying) with a dbh ≥12 cm.
(24)
i
Sum of the stem cross-sectional areas at a height of 1.3 m (level for measuring diameter at breast height [dbh]) of all dead trees and shrubs (standing and lying) with a dbh ≥12 cm according to the method used in NFI1. In NFI1, dead trees were only included if their wood was still usable.
(24)
i
Sum of the stem cross-sectional areas at a height of 1.3 m (level for measuring diameter at breast height [dbh]) of all living and dead trees and shrubs (standing and lying) with a dbh ≥12 cm according to the method used in NFI1. In NFI1, dead trees were only included if their wood was still usable. The total basal area NFI1 corresponds to the sum of the basal area and the deadwood basal area NFI1.
biomass
(36)
i
Dry weight (mass) of living trees and shrubs with a diameter at breast height (dbh) ≥12 cm. The tree parts considered are: the roots, stemwood, branchwood and needles/leaves.
number of stems
(36)
i
Number of stems of dead trees and shrubs (standing and lying) with a diameter at breast height (dbh) ≥12 cm recorded according to the NFI1 method. In NFI1, dead trees were only included if their wood was still usable. In addition, lying but still green trees were classified as deadwood.
(516)
i
Number of stems of living trees and shrubs (standing and lying) with a diameter at breast height (dbh) ≥12 cm.
(84)
i
Number of stems of all living and dead trees and shrubs (standing and lying) with a diameter at breast height (dbh) ≥12 cm according to the method used in NFI1. In NFI1, dead trees were only included if their wood was still usable. The total number of stems NFI1 is the sum of the number of stems and the number of deadwood stems NFI1.
volume
(852)
i
Stemwood volume of living trees and shrubs (standing and lying) with a diameter at breast height (dbh) ≥12 cm with bark.
(36)
i
Stemwood volume of all living and dead trees and shrubs (standing and lying) with a diameter at breast height (dbh) ≥12 cm with bark according to the method used in NFI1. In NFI1, dead trees were only included if their wood was still usable.
(84)
i
