Linear regressions between aboveground biomass estimated with allometric equations with real aboveground biomass values: using field tree height and model (1) (a), using UAV-derived tree height and model (1) (b), using field tree height and model (2) (c), and using UAV-derived tree height and model (2) (d). RMSE, root-mean-square error; MBE, mean bias error
