Summary Contact Technical specs In/Output Process Testing Other Component info Also known as Model type Single Model part of larger framework LandLab Note on status model Date note status model 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.
