Description
Function to estimate tree biomass using Chave et al. (2005) equation for wet forests.
Height is estimated using Feldpausch (2011) regional parameters with Weibull equation.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) and Allometric RegionID.The function assumes that the diameter used is DBH4, unless other DBH is selected.
See ForestPlots.net documentaion for more information.
Usage
1
AGBChv05WH(xdataset, dbh = "D4", height.data = NULL, param.type = "Best")
Arguments
xdataset
a dataset for estimating biomass
dbh
a diameter (in mm).
height.data
Object returned by param.merge. If NULL (default), then regional height-diameter equations are used.
param.type
Local height diameter to use. One of Best (defualt), BioRF,ClusterF ... NEED TO DECIDE WHICH OF THESE TO RETURN
