Stand values

Description

Functions to calculate stand attributes of a forest object.

Usage

stand_basalArea(x, minDBH = 7.5)

stand_foliarBiomass(x, SpParams, gdd = NA_real_)

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

stand_shrubVolume(x, SpParams)

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

stand_dominantTreeDiameter(x, minDBH = 7.5)

stand_treeDensity(x, minDBH = 7.5)

stand_meanTreeHeight(x, minDBH = 7.5)

stand_dominantTreeHeight(x, minDBH = 7.5)

stand_hartBeckingIndex(x, minDBH = 7.5)

stand_quadraticMeanTreeDiameter(x, minDBH = 7.5)

stand_dominantTreeSpecies(x, SpParams)

Arguments

x	An object of class forest.
minDBH	Minimum diameter at breast height (in cm) to include in estimation.
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)

Value

• stand_basalArea: Stand basal area (m2/ha).

• stand_treeDensity: Stand tree density (in ind/ha).

• stand_dominantTreeDiameter: Dominant tree diameter, i.e the average diameter of the 100 widest trees (in cm).

• stand_quadraticMeanTreeDiameter: Quadratic mean tree diameter, i.e. the diameter value corresponding to the current basal area and density.

• stand_meanTreeHeight: Mean tree height (in cm).

• stand_dominantTreeHeight: Dominant tree height, i.e the average height of the 100 tallest trees (in cm).

• stand_dominantTreeSpecies: Dominant tree species name, determined in terms of basal area (and considering all tree sizes).

• stand_hartBeckingIndex: Hart-Becking index.

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

• stand_fuel: Stand fine fuel load (in kg/m2).

• stand_LAI: Stand leaf area index (m2/m2).

• stand_shrubVolume: Stand shrub phytovolume (m3/m2).
