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... -
Yield of merchantable timber
Wood volume of the stem (without bark and stump) and the branches (with bark) at least 7 cm in diameter (limit for coarse wood) from trees and shrubs starting at 12 cm dbh that... -
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... -
Yield of merchantable branches
Wood volume of branches with bark at least 7 cm in diameter (limit for coarse wood) of all living trees and shrubs starting at 12 cm dbh that were present in the pre-inventory... -
Biomass of lying dead trees
Dry weight (mass) of dead, lying trees and shrubs starting at 12 cm dbh. This consists of the tree parts: roots, stemwood and also, depending on the degree of decomposition of... -
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,... -
Mass of needles or leaves of live trees
Dry weight (mass) of the needles and leaves of the living trees and shrubs starting at 12 cm dbh. Citation: Abegg, M.; Brändli, U.-B.; Cioldi, F.; Fischer, C.; Herold-Bonardi,... -
Yield
Volume of stemwood with bark of all trees and shrubs starting at 12 cm dbh that were felled between two inventories. The correction for bias with the sample Tarif trees may be... -
Volume of bole wood (HG 2000)
Wood volume of the stem without bark or stump at least 7 cm in diameter (limit of coarse wood) of all trees and shrubs starting at 12 cm dbh, based on the stem-form functions... -
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.;... -
Yield of live bole wood
Volume of stemwood at least 7 cm in diameter (limit for coarse wood) without the bark and stump that were living trees or shrubs starting at 12 cm dbh in the pre-inventory and... -
Area of shrub forest
All plots classified as shrub forest according to the NFI forest definition. Citation: Abegg, M.; Brändli, U.-B.; Cioldi, F.; Fischer, C.; Herold-Bonardi, A.; Huber M.; Keller,... -
Volume
Volume of stemwood with bark of living trees and shrubs (standing and lying) starting at 12 cm dbh. This corresponds internationally to the "growing stock". The correction for... -
Yield*
Volume of stemwood with bark of all trees and shrubs starting at 12 cm dbh cut between two inventories. *In the calculation no D7/tree height data were used. The values... -
Bole wood mass of live trees
Dry weight (mass) of the stemwood with bark of the living trees and shrubs starting at 12 cm dbh. The correction for bias with the sample Tarif trees may be so drastic that... -
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... -
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... -
Root mass of live trees (Zell, Wutzler)
Dry weight (mass) of the belowground part (roots) of living trees and shrubs starting at 12 cm dbh. The dimensions of the roots are determined according to Zell and Wutzler.... -
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... -
Total stem number NFI1
Number of stems of all living and dead trees and shrubs starting at 12 cm dbh recorded according to the NFI1 method. In NFI1 only those dead trees were recorded whose wood...
