directionalfellingsuccessdef: Directional felling success definition

In thomasgaquiere/Maria: Simulate Different Forms of Logging on a Forest

Description

Defines whether the directed fall of the tree is successful or not by drawing in a Bernoulli distribution where the probability of success is by default 60%, and can be changed with the advancedloggingparameters argument.

Usage

directionalfellingsuccessdef(
  inventory,
  fuel,
  directionalfelling,
  advancedloggingparameters = loggingparameters()
)

Arguments

inventory	input inventory (see the inputs formats and metadata in the vignette) (data.frame)
fuel	Fuel wood exploitation: no exploitation = "0", exploitation of damage and unused part of logged trees for fuel = "1", exploitation of hollow trees, damage and and unused part of the log for fuel = "2"
directionalfelling	Directional felling = "0" (absent), "1" (only to avoid damage to future and reserve trees), "2" (to avoid damage to future and reserve trees and to position the log relative to the track)
advancedloggingparameters	Other parameters of the logging simulator loggingparameters (list)

Value

Input inventory with the "TreeFellingOrientationSuccess" new column (see the outputs metadata in the vignette).

Examples

data(MainTrails)
data(HarvestablePolygons)

inventory <- addtreedim(inventorycheckformat(Paracou6_2016),
volumeparameters = ForestZoneVolumeParametersTable)

inventory <- treeselection(inventory, objective = 20, scenario ="manual",
 fuel = "2", diversification = TRUE, specieslax = FALSE, maintrails = MainTrails,
 harvestablepolygons = HarvestablePolygons,
 objectivelax = TRUE, topography = DTMParacou, plotslope = PlotSlope,
 speciescriteria = SpeciesCriteria,
 advancedloggingparameters = loggingparameters())$inventory

new <- directionalfellingsuccessdef(inventory,fuel = "2", directionalfelling = "2",
advancedloggingparameters = loggingparameters())
