i
Indication as to whether forest planning documents exist at the local level (operational plan, silvicultural project, etc.) and/or at the cantonal level (forest development plan or regional/cantonal forest plan). These documents provide the basis for the forest manager to make silvicultural or operational decisions, irrespective of the year they were produced. Reference: Forest Service Survey (MID 2028: lokale forstliche Planungswerke, MID 803: Stand der Waldentwicklungspläne WEP)

region

(4)
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.
