| Table 2. Linear mixed models for the different variables. Stand values except for age, height, and diameter at breast height (DBH) have been scaled up to one hectare. Disturbing factor, intensity and transect position indicate the fixed effects. All analyses were conducted on larches only. Site codes: LID = Low Intensity Disturbance, RB = River Bank, Log/ID = Logging/Intense Disturbance 1&2, M = Meander 1&2, P = Polygon. | |||||||||||||
