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 possibly projected according to climate change model
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 basal area.
SI Management H100 m Site index for management to be used when calculating LSÅ
Initial Min Final Felling Age yr Initial Min Final Felling Age
Min Final Felling Age yr Min Final Felling Age
Dominant Height m Dominant height based on 100 thickest trees per ha of dominant species
Dominant Height From Hgv m Dominant height estimated from the basal area weighted height (Hgv)
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 Overstorey cm Basal area weighted Mean diameter for overstorey trees
Dgv cm Basal area weighted Mean diameter for non-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.
