Median of (a) soil C content (g kg−1), (b) soil N content (g kg−1), (c) soil δ13C (‰) and (d) soil δ15N (‰) at 0–100 cm soil depth across different forest type and among sites. NF: Natural Forest; PF: Plantation Forest. A segment inside the rectangle shows the median. The boundary of the box indicates the distribution of soil samples (25th and 75th percentile). Error bars denote the maximum and minimum (90th and 10th percentiles).
