  • Stand density (SDI)

    The Stand Density Index (SDI) is a general measure for the density of a stocking and is based on the number of stems/ha and the average diameter of the tally trees on the sample...

  • 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...
  • 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...
  • 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...
  • 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,...
  • 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...
  • Increment
