1-dimensional model effects of the scam (Eq. 8) on the first order parameter A and the first order parameter B [m1b(Dg)] for spruce, pine and birch. Additionally, an estimate of tree height (m) under constant predictors (dbh = 20 cm, Alt = 300 m, qmD = 25 cm, BAL = 0.5 m2 per 250 m2, SD = III) but varying regional locations is shown in order to display the 2-dimensional effect f sp a (east k , north k ) (each time on the bottom line, right)
