AGBChv05DH: Function to estimate tree biomass for dry forests (Chave et...

Description Usage Arguments Author(s) References

Description

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.

Usage

1
AGBChv05DH(xdataset, dbh = "D4", height.data = NULL, param.type = "Best")

Arguments

xdataset

a dataset for estimating individual tree 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
