Dominant species is used to determine...
- ...what species to include when computing dominant height, which is used as input to thinning guide.
- ...what species to compute SiteIndexH for.
Dominant Species: Regeneration species, i.e. the species that was planted.
Young stands: Species proportion is computed as proportion of trees.
Established stands: Species proportion is computed as proprtion of basal area.
Calculation: If number of conifers >= 500 trees/ha, or sum of conifer proportions >= 50 %, then pine, spruce or contorta is selected as dominant species depending of which is most abundant. Otherwise, if one of oak, beech, or birch >= 50 %, then that one is selected. Otherwise, "other decidouos" is selected, which includes other broad-leafs.
