Classification

(12)
i
Altitudinal vegetation belts in the system used in the guidelines for monitoring the sustainability and performance of protection forests (NaiS; Frehner et al. 2005), reduced to six classes. The variable represents a simplification of the NaiS altitudinal vegetation belts with ten classes (NAISHSTKOMB) in which the classes «hyperinsubric» and «colline» are merged with «colline with beech» to form the class «hyperinsubric and colline» and the class «lower montane» with «upper montane» and «lower/upper montane» to form the class «lower and upper montane». The information is based on the altitudinal vegetation belts determined by experts (accessible forest sample plots of NFI4 on the 1.4-km network; Arge Frehner et al. 2020), as well as on the altitudinal vegetation belts modelled for the period 1981-2010 (other sample plots; Zischg et al. 2021).

i
Obstruction directly at the forest edge that makes it difficult or impossible for humans or animals to enter or leave the forest or restricts the spread of the shrub belt or herbaceous fringe - in ten classes. Reference: Field Survey (MID 982: Art der Waldrandbegrenzung)
(2)
i
Density of shelterbelt (forest mantle) and shrub belt with foliage from the ground to a height of 2 m - in four classes. Reference: Field Survey (MID: 43: Waldranddichte)
(6)
i
Ecological value of the forest edge according to the number of woody species present, as well as the weighted proportion of thorny shrubs, short-lived, light-demanding softwoods (birches, alders, poplars and willows) and other ecologically valuable woody species (e.g. oaks and rowan) – in three classes. Reference: Field Survey (MID 568: Pflanzenarten am Waldrand)
(2)
i
Ecological value of the forest edge as a habitat for animals and plants, classified into three classes according to the structural diversity and diversity of woody species along the forest edge. Reference: Field Survey (various attributes)

region

(36)
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
Forest edge in the NaiS altitudinal vegetation belts: «hyperinsubric», «colline», «colline with beech», «submontane», «lower montane», «upper montane», «lower/upper montane» and «high montane», which was recorded during the two inventories NFI4 and NFI5. Reference: Field Survey (MID 29: Waldrandbeschreibung)
