Constructor for species class

Only used in the matreex package

Usage

new_species(
  IPM,
  init_pop,
  harvest_fun,
  disturb_fun,
  harv_lim = c(dth = 175, dha = 575, hmax = 1),
  rdi_coef = NULL,
  disturb_coef = NULL,
  type = c("Undefined", "Broadleaf", "Coniferous")
)

Arguments

IPM

ipm class object from the matreex package.

init_pop

Function to initiate the population at simulation start. Arguments must be mesh and SurfEch. Using the arguments is not mandatory, it's most useful when creating random population.

harvest_fun

Function to impact the population with harvest rule. Argument must be x, species, ...,

disturb_fun

Function to impact the population with possibles disturbances. Extra care is needed to give this function all needed parameters. Default is def_disturb.

harv_lim

Limits of harvest for a population size distribution.

dth

minimum diameter at which we cut the size distribution

dha

harvest diameter

hmax

maximum harvest rate for a size class

rdi_coef

Coefficient for RDI curve used in even harvest. The model require the intercept and slope.

disturb_coef

Species coefficient for disturbance reaction. These values and names are highly dependent on the disturbance function. BAtarget, ct and t. Should return a population state as it's take it in input, with less population than before. Unless you want zombie trees. It represent the distribution of the population to harvest

type

Type of the tree, choosing between "Broadleaf" and "Coniferous". This value is only used during biotic disturbance with a specific disturb_fun. This is experimental
