STRBREITE gibt an, wie breit der betreffende Strecken-/Strassenabschnitt ist. Lastwagenstrassen im Schweizer Wald müssen, um in der Erschliessungserhebung erfasst zu werden, eine Mindestbreite von 2.50 m aufweisen, wobei der Strassenoberbau mindestens für eine Achslast von 10 t ausgelegt sein muss. Im Rahmen der Försterumfrage des LFI4 wurden zusätzliche Informationen erhoben. Dabei steht nicht die lastwagenbefahrbare Strasse nach LFI mit 10 t Achslast und einer Mindestbreite von 2.50 m im Fokus, sondern die für die Holzabfuhr relevante Strasse mit mindestens 3 m Fahrbahnbreite und genügender Tragfähigkeit für Fahrzeuge mit einem Gesamtgewicht ab 26 t.

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.

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.

Forest of which less than two-thirds is covered with shrubs that can be accessed on foot.

grid

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.
