exampleStandDynamics: Example forest dynamics by species

In miquelcaceres/IFNdyn: IFN forest dynamics and scenario analysis

Description

Simulates stand dynamics and plots the temporal series of a stand-level variable.

Usage

exampleStandDynamics(
  species,
  prov = 8,
  initialDBH = NULL,
  numSteps = 20,
  SWHC = 150,
  Rad = 25,
  Temp = 13,
  Prec = 900,
  PET = 1000,
  slope = 0,
  elevation = 100,
  testClimateChange = FALSE,
  ...
)

Arguments

species	Character vector of species codes to be studied.
prov	A character or integer of Spanish province between 1 and 50. Rellevant for regionalized species models.
initialDBH	Numeric vector with initial diameter values (in cm). Initial density associated to each tree record will depend on diameter.
numSteps	Number of 10-yr steps to be simulated.
SWHC	Soil water holding capacity (mm).
Rad	Average daily radiation (MJ).
Temp	Mean annual temperature (degrees C).
Prec	Mean annual precipitation (mm)
PET	Mean annual potential evapotranspiration (mm)
slope	Slope in degrees.
elevation	Elevation (m.a.s.l.).
testClimateChange	Boolean flag to include simulations with altered climate

Value

A list with two elements:

• standDynamics: A list with one data frame per species with the complete stand dynamics (tree data per step).

• finalStates: A list with one data frame per species with the final tree data at the end of the simulation.

Examples

pines = c("21", "22", "23", "24", "25", "26", "27","28","31","17")
oaks = c("45", "44", "41", "43", "71","72")
other = c("51", "55","60", "73", "3","37", "83", "80")
sdyn = exampleStandDynamics(species=pines, numSteps = 40)
