    Volume of stemwood with bark of all trees and shrubs starting at 12 cm dbh removed from the forest due to damage occurring (e.g. windthrow, avalanches, insects or rockfall),...
  • Basal area

    Sum of the stem cross-section areas of all living trees and shrubs starting at 12 cm dbh (standing and lying) at a height of 1.3 m (dbh measurement height). Citation: Abegg,...
  • Basal area of dead wood NFI1

    Sum of stem cross-section areas of all dead trees in a stand at a height of 1.3 m (dbh measurement height) recorded according to the NFI1 method. Citation: Abegg, M.; Brändli,...
  • Basal area of dead wood

    Sum of the stem cross-section areas of all dead trees in a stand at a height of 1.3 m (dbh measurement height). Citation: Abegg, M.; Brändli, U.-B.; Cioldi, F.; Fischer, C.;...
  • Diversity of woody species

    Index based on the number of tree and shrub species starting at 12 cm dbh in the upper layer and the occurrence of especially ecologically valuable tree and shrub species...
  • Forest area

    The forest area is the total sum of all areas classified as forest according to NFI’s forest definition. The forest definition includes shrub forest. This theme is also used to...
  • Forest area by natural hazard

    For each natural hazard process according to FOEN’s SilvaProtectCH, the size of the forest area affected is given. One forest region may be affected by several different natural...
  • Increment

    Increase in the volume of stemwood with bark of the trees and shrubs starting at 12 cm dbh that have survived between two inventories and of the losses (modelled for the half...
  • Increment*

    Increase in the volume of stemwood with bark of the surviving trees and shrubs starting at 12 cm dbh between two inventories and the losses (modelled for the half period), plus...
  • Length of forest roads

    The length of forest roads corresponds to the length of the NFI forest roads. This length was calculated according to the method of the specific NFI concerned. Citation: Abegg,...
  • Mortality

    Volume of stemwood with bark of all trees and shrubs starting at 12 cm dbh that died or disappeared between two inventories and that were not harvested. The correction for bias...
  • Mortality*

    Volume of stemwood with bark of all trees and shrubs starting at 12 cm dbh that died or disappeared between two inventories, but were not cut. *In the calculation no D7/tree...
  • Number of forest plots

    Number of forest sample plots (Plots). Citation: Abegg, M.; Brändli, U.-B.; Cioldi, F.; Fischer, C.; Herold-Bonardi, A.; Huber M.; Keller, M.; Meile, R.; Rösler, E.; Speich,...
  • Net increment*

    Increment with ingrowth minus the mortality. *In the calculation no D7/tree height data were used. The values calculated like this have not been corrected for bias, but allow...
  • Net increment

    Increment including ingrowth minus the mortality. The correction for bias with the sample Tarif trees may be so drastic that it results in negative values with small numbers...
  • Number of woody species (from 40 cm height)

    Number of species of living trees and shrubs starting at 40 cm plant height that occur within a 200 m2 sample plot. Citation: Abegg, M.; Brändli, U.-B.; Cioldi, F.; Fischer,...
