i
Dry weight (mass) of standing and lying deadwood, determined with the help of the species- and decomposition-dependent wood densities of the following components: 1) stemwood, merchantable branchwood, branch brushwood and roots of standing and lying dead trees and shrubs with a diameter at breast height (dbh) ≥12 cm without stem breakage; 2) stemwood of the still standing stump, branch brushwood and roots of standing dead trees and shrubs ≥12 cm dbh with stem breakage and 3) LIS-deadwood, i.e. the lying deadwood with a diameter ≥7 cm (merchantable wood without merchantable wood pieces in heaps of branches), which cannot be assigned to a tree or shrub ≥12 cm dbh.

i
Forest ownership, classified according to the two categories: 'public' and 'private'. Reference: Forest Service Survey (MID 365: Eigentum)

region

i
Demarcation of Switzerland into five regions (Jura, Plateau, Pre-Alps, Alps and Southern Alps) with relatively uniform growth and timber production conditions. The production regions were established by the Federal Office of Forestry long before the first National Forest Inventory (NFI1, 1983-1985). With a small exception along Lake Geneva, the boundaries of the production regions still follow the municipal boundaries of the time. Unlike the NFI, the Forestry Statistics of the Federal Statistical Office don't use the production regions as demarcation but rather the forestry zones, whose boundaries are somewhat different.

i
Division of Switzerland into 14 regions (2 in the Jura, 3 on the Plateau, 3 in the Pre-Alps, 5 in the Alps and 1 in the Southern Alps). The economic regions are a subdivision of the production regions according to economic-geographical criteria.
(3)
i
Demarcation of Switzerland used in NFI for protection forest analyses. The six protection forest regions were derived from the economic regions by combining individual regions according to natural and statistical criteria.
(3)
i
Regional demarcation with the cantons as a unit, with the two half-cantons, Basel-Land and Basel-Stadt, combined into one canton for statistical reasons.
(3)
i
Demarcation of Switzerland into six regions with similar flora and fauna. The six regions correspond to the basic categories in the publication «The Biogeographical Regions of Switzerland», which was published by FOEN in 2022.

i
NFI's sampling grid with a mesh size of 1.4 km. The 1.4-km grid is the grid size covering all the previous terrestrial Inventories, which is why it is also called the base grid.
