Fig. 3. Relationship between the number of plots and the coefficient of variation for forest biomass measurements by community members (stippled red line) and professional foresters (black line) in lowland dipterocarp forest in Batu Majang, Indonesia (a), mountain rain forest in Manlin, China (b–c), evergreen monsoon forest in Sakok, Laos (d–e), and Diem (f) and Moi (g), Vietnam (with coefficient of variation = 15% dashed line; n = 289 permanent plots). Data from the three sites in Moi were lumped together for the purpose of preparing this figure.
