Detailed Description

Establishment deals with the establishment process of saplings.

http://iland-model.org/establishment Prerequisites for establishment are: the availability of seeds: derived from the seed-maps per Species (

Member Function Documentation

abioticEnvironment()

double Establishment::abioticEnvironment ( ) const

inline

integrated value of abiotic environment (i.e.: TACA-climate + total iLand environment)

avgLIFValue()

double Establishment::avgLIFValue ( ) const

inline

average LIF value of LIF pixels where establishment is tested

avgSeedDensity()

double Establishment::avgSeedDensity ( ) const

calculateAbioticEnvironment()

void Establishment::calculateAbioticEnvironment

(

)

calculate the abiotic environment (TACA model)

Calculate the abiotic environemnt for seedling for a given species and a given resource unit.

The model is closely based on the TACA approach of Nitschke and Innes (2008), Ecol. Model 210, 263-277 more details: http://iland-model.org/establishment#abiotic_environment a model mockup in R: script_establishment.r
