speciesfuelloading(x, type = "total", allometric = TRUE,
  excludeSSP = TRUE, agg = "none", customParams = NULL, na.rm = TRUE)

Arguments

x

data frame with columns 'plot', 'species', 'H' (mean height in cm), 'C' (cover in percent)

type

either 'total' (total fuel) or 'fine' (fine fuels)

allometric

wether to use allometric equations or bulk density estimates

excludeSSP

excludes subspecies information for species matching

agg

aggregation of results. Either 'none' or 'plot'

customParams

custom allometry parameter table (for species not in default params)

na.rm

whether to exclude missing values when aggregating loading

Value

a vector with loading values (kg/m2)
