i
Forest area closest to young forest plants with a particular type of damage. Young forest plants are trees and shrubs ≥10 cm in height and ≤11.9 cm in diameter at breast height (dbh). However, depending on the inventory, only trees ( NFI3, NFI5) or only trees and selected shrub species (NFI4) were recorded as the nearest young forest plant. Since a young forest plant may have several different types of damage, it can contribute to areas with several different damage types at the same time.

i
Damage to young forest plants ≥10 cm in height and ≤11.9 cm in diameter at breast height (dbh), whereby browsing is only assessed on specimens ≤129 cm in height, – in eight classess. Reference: Field Survey (MID 127: Gipfeldürre, MID 174: Verbiss des Leittriebes, MID 977: Fegeschaden, MID 987: Schälschaden, MID 184: Krankheit; MID 183: Holzereischaden, MID 185: anderer Schaden)

i
Species of young forest plants ≥10 cm in height and ≤11.9 cm in diameter at breast height (dbh) with individual classes for the ten most important species or species groups in Switzerland («main tree species»), as well as the classes «other conifers», «other broadleaves» and «species not assessed in all inventories». The main tree species are spruce (Picea spp.), fir (Abies spp.), pine (Pinus sylvestris, P. nigra, P. strobus, P. mugo subsp. uncinata), larch (Larix spp. ), Arolla pine (Pinus cembra), beech (Fagus sylvatica), maple (Acer spp.), ash (Fraxinus spp.), oak (Quercus spp.) and chestnut (Castanea sativa). Reference: Field Survey (MID 1050: Jungwaldpflanzenart - nächste Pflanze)
