  1. Values refer to a soil depth of 0–25 cm
  2. Data are presented as mean ± standard error (n = 33). Mean followed by letters A, B are significantly different between biomass and necromass within a category. Means followed by the letters a and b are significantly different between sites within a category. Means followed by letters α, β, γ are significantly different between categories within a site. No letters are displayed in the absence of a significative difference. 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
