This result group contains: State for each treatment unit. Results include data for each treatment unit, alternative and time period. Please note that species-wise data is placed in a separate group (Data per Species).
| Variable name | Unit | Description |
| 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 | yr | Basal area weighted mean age all trees, including overstorey trees. |
| Mean Age Main Saplings | m | Mean age of main saplings |
| Stand Age | yr | Years since regeneration |
| 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) |
| Closure | unitless | Ratio between the volume of the forest, compared to the volume that would be optimal to harness the wood production potential of the site. In young stands, the number of main saplings is used instead of volume. |
| Dgv | cm | Basal area weighted mean diameter of trees, excluding overstorey trees |
| Dgv Overstorey | cm | Basal area weighted mean diameter of overstorey trees |
| 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) |
| Mean Height Main Saplings (arithmetic) | m | Arithmetic mean height for main saplings (calculated as weighted averaged using calculated crop tree probabibilites as weights) |
| Mean Height All Saplings (arithmetic) | m | Arithmetic mean height for all saplings |
| SI Management | H100 m | Site index for management to be used when calculating minimum final felling age (LSÅ) |
| Dominant Species | species | Regeneration species or species with largest basal area or stems |
| Dominant Height | m | Dominant height based on the 100 largest trees (with respect to tree diameter) per ha of dominant species |
| Dominant Height From Dgv | 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 |
| 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. |
| 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. |
| SIS (projected) | H100 m | Site index determined from site index factors, and adjusted for climate change if climate model is actived. |
| SIH (estimated) | H100 m | see Variable:SiteIndexH (SIH). Calculated with site index equations for height development of dominant trees. H100, for birch H50. |
