Values refer to a soil depth of 0–25 cm
Data are presented as mean ± standard error (n = 10). Mean followed by letters a and b are significantly different between sites. No letters are displayed in the absence of a significative difference. Site-scale values were computed using relative densities from Table 1. Seedlings, juveniles and adults were palms < 1 m, 1−3 m and > 3 m in height, respectively. Trees were individuals > 10 cm DBH. Moderately degraded and heavily degraded are abbreviated as mDeg and hDeg, respectively
