	~~Domainant species~~:		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.
