Species values: Species description functions

Description

Functions to calculate attributes of a forest object by species.

Usage

species_basalArea(x, SpParams)
species_cover(x, SpParams)
species_density(x, SpParams)
species_foliarBiomass(x, SpParams, gdd = NA)
species_fuel(x, SpParams, gdd = NA, includeDead = TRUE)
species_LAI(x, SpParams, gdd = NA)
species_phytovolume(x, SpParams)

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.

Value

A vector with values for each species in SpParams:

• species_basalArea: Species basal area (m2/ha).

• species_cover: Shrub cover (in percent).

• species_density: Plant density (ind/ha). Tree density is directly taken from the forest object, while the shrub density is estimated from cover and height by calculating the area of a single individual.

• species_foliarBiomass: Standing biomass of leaves (in kg/m2).

• species_fuel: Fine fuel load (in kg/m2).

• species_LAI: Leaf area index (m2/m2).

• species_phytovolume: Shrub phytovolume (m3/m2).
