Table S2 Soil properties at 0–10 cm depth seven years after thinning. Values in parentheses indicate standard errors. Different letters indicate significant differences between the treatments at each site in each sampling period (n = 3; P < 0.05). Asterisks indicate significant differences between the sampling periods within each treatment at each site (n = 3; P < 0.05)
