Species description functions

Description

Functions to calculate attributes of a forest object by species or to extract species parameters from a species parameter table (SpParamsMED).

Usage

species_basalArea(x, SpParams)

species_cover(x, SpParams)

species_density(x, SpParams)

species_foliarBiomass(x, SpParams, gdd = NA_real_)

species_fuelLoading(x, SpParams, gdd = NA_real_, includeDead = TRUE)

species_LAI(x, SpParams, gdd = NA_real_, bounded = TRUE)

species_characterParameter(species, SpParams, parName)

species_parameter(
  species,
  SpParams,
  parName,
  fillMissing = TRUE,
  fillWithGenus = TRUE
)

Arguments

x

An object of class forest.

SpParams

A data frame with species parameters (see SpParamsMED).

gdd

Growth degree days (to account for leaf phenology effects).

includeDead

A flag to indicate that standing dead fuels (dead branches) are included.

bounded

A boolean flag to indicate that extreme values should be prevented (maximum tree LAI = 7 and maximum shrub LAI = 3)

species

A character vector of species names.

parName

A string with a parameter name.

fillMissing

A boolean flag to try imputation on missing values.

fillWithGenus

A boolean flag to try imputation of missing values using genus values.

Value

A vector with values for each species in SpParams:
