regeneration: Plant regeneration

Description

Annual plant regeneration from seed recruitment or from resprouting

Usage

recruitment(
  forest,
  SpParams,
  control,
  minMonthTemp,
  moistureIndex,
  verbose = FALSE
)
resprouting(
  forest,
  internalMortality,
  SpParams,
  control,
  management_results = NULL
)

Value

An object of class forest with the new plant cohorts.

Arguments

forest

An object of class forest.

SpParams

A data frame with species parameters (see SpParamsMED and SpParamsDefinition).

control

A list with default control parameters (see defaultControl).

minMonthTemp

Minimum month temperature.

moistureIndex

Moisture index (annual precipitation over annual potential evapotranspiration).

verbose

Boolean flag to indicate console output during calculations.

internalMortality

A data frame with mortality occurred in the last year of simulation.

management_results

The result of calling a management function (see defaultManagementFunction).

Details

• Species can recruit if adults (sufficiently tall individuals) are present (seed rain can also be specified in a control parameter). Minimum month temperature and moisture index values are used to determine if recruitment was successful. Species also require a minimum amount of light at the ground level.

• Resprouting occurs after “mortality” from die-back (including drought- or pathogen-induced dessication), cutting or burning of the aerial part in a species with resprouting ability, but not after carbon starvation or baseline mortality (unspecific mortality causes).
