Variance of biomass estimates (square
root transformed) p 
Tree girth (cm) p† 
Plot
demarcation (Tree inclusion and
exclusion) p† 
†In brackets, the proportion of measured trees (tree girth) and plots (plot demarcation) where community members’ and foresters’ measurements had a perfect match.
‡One plot was excluded because it violated 3x standard deviation of the mean. (For Batu Majang, Indonesia, n = 63; for Moi [i], Vietnam, n = 26)
§ Data are not available because trees were not individually marked.
 No p value is available because too few degrees of freedom exist for Wilcoxon’s signed rank test.
