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.

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. The total basal area corresponds to the sum of the basal area and the deadwood basal area.

Stemwood volume of all trees and shrubs with a diameter at breast height (dbh) ≥12 cm with bark that were harvested between two inventories.

Stemwood volume of all trees and shrubs with a diameter at breast height (dbh) ≥12 cm with bark that were harvested, died or disappeared between two inventories.

Increase in stemwood volume between two inventories of all surviving trees and shrubs with a diameter at breast height (dbh) ≥12 cm with bark, the stemwood volume of all ingrowing trees and shrubs with bark, and the modelled increase in the stemwood volume of the losses with bark during half the inventory period.

Increase in the stemwood volume between two inventories of all surviving trees and shrubs with a diameter at breast height (dbh) ≥12 cm with bark, the stemwood volume of all ingrowing trees and shrubs with bark, and the modelled increase in the stemwood volume of the losses with bark during half the inventory period minus the volume of mortality. The net increment thus corresponds to the increment (=gross increment) minus the volume of mortality.

Stemwood volume of all trees and shrubs with a diameter at breast height (dbh) ≥12 cm with bark that were harvested, died or disappeared between two inventories.

Stemwood volume of all trees and shrubs with a diameter at breast height (dbh) ≥12 cm with bark that died naturally between two inventories (e.g. due to windthrow or insects) or disappeared (e.g. due to avalanches), but that were not harvested. Mortality is the sum of natural losses and the remaining mortality.

Number of stems of living trees and shrubs (standing and lying) with a diameter at breast height (dbh) ≥12 cm.

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.

Stemwood volume of living trees and shrubs (standing and lying) with a diameter at breast height (dbh) ≥12 cm with bark.

Stemwood volume of all living and dead trees and shrubs (standing and lying) with a diameter at breast height (dbh) ≥12 cm with bark. The total wood volume is the sum of the growing stock and deadwood volumes.

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.

Wood volume of the stem without bark or stump ≥7 cm in diameter (limit for merchantable wood) of all trees and shrubs with a diameter at breast height (dbh) ≥12 cm, based on the stem-form functions according to Kaufmann (2001). The definition of the assortments is based on the 2010 edition of the Swiss trading customs for raw timber (HG 2010).

Volume of stemwood of all dead trees and shrubs (standing and lying) with a diameter at breast height (dbh) ≥12 cm with bark.
