Variable name | Unit | Description |
Dominant Species | species | Regeneration species or species with largest basal area or stems |
SIS (projected) | H100 m | Site Index determined from site index factor, and adjusted for climate change if climate model is actived. |
SIH (estimated) | H100 m | Site index calculated with site index equations for height development of dominant trees. H100, for birch H50. Requires dominant species has ≥ 70 % of the basal area. |
SI Management | H100 m | Site index for management to be used when calculating minimum final felling age (LSÅ) |
Initial Min Final Felling Age | yr | Initial minimum final felling age (in year 0). |
Min Final Felling Age | yr | Minimum final felling age. This can change over time if the next generation is regenerated with another species. |
Dominant Height | m | Dominant height based on the 100 largest trees (with respect to tree diameter) per ha of dominant species |
Dominant Height From Hgv | m | Dominant height calculated with a function using Hgv as explantory variable (Björn Elfving) |
Dominant Height From Trees | m | Dominant height calculated from tree list |
Mean Age (excl. overstorey) | yr | Mean total age for non-overstorey trees, basal area weighted if established stand, arithmetic of main saplings if young stand |
Mean Age (all trees, always basal area weighted)----> Mean Age | yr | Basal area weighted mean age all trees. |
Mean Age Main Saplings | m | Mean age of main saplings |
Dgv | cm | Basal area weighted mean diameter of trees, excluding overstorey trees |
Dgv Overstorey | cm | Basal area weighted mean diameter of overstorey trees |
Mean Height Main Saplings (arithmetic) | m | Arithmetic mean height for main saplings |
Mean Height All Saplings (arithmetic) | m | Arithmetic mean height for all saplings |
Hgv | m | Basal area weighted mean height for non-overstorey trees |
Hgv Overstorey | m | Basal area weighted mean height for overstorey trees (retention-, seed- and shelterwood trees) |
Basal area (incl overstorey)---->Basal area (incl. overstorey) | m2/ha | Basal area including overstorey trees |
Basal area (excl. overstorey) | m2/ha | Basal area excl. Overstorey |
Basal area (overstorey) | m2/ha | Basal area of overstorey trees (retention-, seed- and shelterwood trees) |
Stand Age | yr | Years since regeneration |
Volume (incl. overstorey) | m3sk/ha | Volume (incl. overstorey) |
Volume overstorey | m3sk/ha | Volume of overstorey trees (retention-, seed- and shelterwood trees) |
Volume (excl. overstorey) | m3sk/ha | Volume (excl. overstorey) |
Volume ≥ 8cm dbh (incl. overstorey) | m3sk/ha | Volume of trees ≥ 8 cm dbh (incl. overstorey) |
Stems | stems/ha | Stem density (all trees) |
Regeneration Species | SpeciesCode | Species for which the current rotation was regenerated (if even-aged management), or dominant species if regeneration species is unknown |
Waiting State | true/false | True if young stand that has not yet reach 2-3 meters height and is waiting to be activated. Interpolated state. |
