Table 3 Structural characteristics of the tree communities based on trees with minimum diameter at breast height (DBH) of 10 cm

From: Patterns of forest composition and their long term environmental drivers in the tropical dry forest transition zone of southern Africa

Mean EVI 2007–2012 0.274 (0.014)b 0.281 (0.015)c 0.266 (0.011)a 0.267 (0.012)a 0.266 (0.013)a
  1. Standard error of the mean is between parentheses. Letters represent significant differences between groups at level p < 0.05. EVI: enhanced vegetation index derived from MODIS time series (Stellmes et al. 2013b). The table is based on a larger dataset than that used for community classification, which used a minimum DBH of 20 cm
