VegCA


Metadata

Also known as
Model type Single
Model part of larger framework LandLab
Incorporated models or components:
Spatial dimensions 2D
Spatial extent Landscape-Scale, Watershed-Scale
Model domain Terrestrial, Ecosystems
One-line model description Landlab component that simulates inter-species plant competition using a 2D cellular automata model.
Extended model description This code is based on Cellular Automata Tree Grass Shrub Simulator (CATGraSS). It simulates spatial competition of multiple plant functional types through establishment and mortality. In the current code, tree, grass and shrubs are used.
Keywords:

population ecology, cellular automata, species, competition,
