Description Usage Arguments Author(s) References
Function to estimate individual tree aboveground biomass using Chave et al. (2005) equation for dry forests. Tree height is estimated from diameter using a Weibull equation with region-specific parameters from Feldpaush et al. (2011). The function adds columns to the dataset that contain the biomass estimates for all living trees. This function needs a dataset with the following columns: PlotViewID, PlotID, TreeID, CensusNo, Diameter (DBH1-DBH4), Wood density (WD) and Allometric RegionID.The function assumes that the diameter that should be used is DBH4, unless another DBH is selected. See ForestPlots.net documentation for more information.
