recruitment: Plant recruitment

Description

Usage

recruitment(forest, SpParams, control, minMonthTemp, moistureIndex)

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).

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.
