stand_dominantTreeSpecies(x, SpParams)
x |
An object of class |
minDBH |
Minimum diameter at breast height (in cm) to include in estimation. |
SpParams |
A data frame with species parameters (see |
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) |
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).
