estimate_biomass: Estimate biomass

In SilviaTerra/rpnc250: R implentation of USFS Research Paper NC-250: Tree Volume and Biomass Equations for the Lake States

Estimate biomass

Description

Estimate green tons of biomass to a given top diameter following the system outlined in the original publication. Biomass of the bole (stem + stump), bark, and top are summed to obtain an estimate of the total biomass.

Usage

estimate_biomass(spcd, dbh, site_index, stand_basal_area)

Arguments

spcd	vector of FIA species codes
dbh	vector of DBH observations in inches
site_index	vector of site index estimates (base age 50)
stand_basal_area	vector of stand-level basal area estimates corresponding to the stems

Value

estimates of biomass in tons

Examples

estimate_biomass(
  spcd = c(541, 371, 95, 73),
  dbh = c(10, 11, 12, 13),
  site_index = c(60, 65, 60, 70),
  stand_basal_area = 80
)
