The Everglades Landscape Model (ELM) is an application instance of the generalized Ecological Landscape Modeling code package. For applications within the Florida Coastal Everglades (FCE) LTER, the ELM is one of the simulation modeling tools used to a) explore hypotheses of ecosystem processes in heterogenous spatial landscapes, b) extrapolate field-scale research findings across space and time, and c) predict the evolution of the Everglades landscape in response to plausible future scenarios. For ELM v.2.8.3-4, the 2 zip-archive packages here contains 1a) all (C) source code and unix (Bourne) shell scripts used to build and run the ELM (& includes Doxygen-generated hyperlinked source code documentation of every file/function/struct/parameter), 1b) all Everglades-specific input data used in historical (1981-2000) simulations; and 2) a complete documentation report with chapters including the Introduction&Goals, Model Data, Model Structure, Model Performance, and Model User's Guide. The ELM is being applied and updated routinely. Such updated information can be found at http://www.ecolandmod.com .
