Table 3 The different definitions used for the dominant tree species in this study

Abbreviation	Definition for the dominant species	Classes¹
Sp_max	Highest species-specific proportion of G per plot.	P, S, D
Sp_max+95	Highest species-specific proportion of G per plot + separately labeled plots with G ≥ 95 % of pine.	P₉₅, P, S, D
Sp₇₅	Species-specific proportion of G ≥ 75 %; plots with a lower dominant proportion pooled in a separate class.	P₇₅, S₇₅, D₇₅, M
Sp₇₅₊₉₅	Species-specific proportion of G ≥ 75 %; plots with a lower dominant proportion pooled in a separate class + separately labeled plots with G ≥ 95 % of pine.	P₉₅, P₇₅, S₇₅, D₇₅, M

¹ Dominated by pine (P), spruce (S), deciduous trees (D), or the aforementioned species with the proportion given in the subscript; or mixed (M)
