Sample plots with/without extensive traces of forest fire (e.g. burnt ground vegetation, charred parts of tree or soil layers) on the interpretation plot (50 × 50 m). Reference: Field Survey (MID 203: Spuren von Waldbrand)

Sample plots with/without traces of landslides (e.g. a toe or crack, and trees leaning uphill) on at least 100 m² of the interpretation area (50 × 50 m). Reference: Field Survey (MID 193: Rutschung)

Sample plots with/without current traces of rockfall on the interpretation plot (50 × 50 m). Reference: Field Survey (MID 195: Steinschlag)

Sample plots with/without traces of snow movement, i.e. snow creep, snow sliding or avalanches on the interpretation area (50 × 50 m). Reference: Field Survey (MID 202: langsame Schneebewegung und MID 400: Lawinenspuren)

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.

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.

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.

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.

Regional demarcation with the forest districts as a unit. This variable was implemented in the year 2024 and is based on a survey with the cantonal forest services in the years 2022/2023.
