Description
Function to estimate tree biomass using Chave et al. (2005) equation for wet forests.The function adds columns to the dataset with the biomass information for all alive trees.
This function needs a dataset with the following information: PlotViewID, PlotID, TreeID, CensusNo, Diameter (DBH1-DBH4), Wood density (WD). The function assumes that the diameter used is DBH4, unless other DBH is selected.
See ForestPlots.net downloads documentation for more information.
