Models in ENVISIONModels in ENVISION Models are “plug-ins” of two types:Models are “plug-ins” of two types:
1)1) Autonomous ProcessesAutonomous Processes: Represent : Represent processes causing landscape changes processes causing landscape changes independent of human decision-making independent of human decision-making – e.g. climate change, vegetative – e.g. climate change, vegetative succession, forest growth, fire, succession, forest growth, fire, flooding, ??? flooding, ???
2)2) Evaluative Models Evaluative Models – Generate – Generate production statistics and report back production statistics and report back how well the landscape is doing a how well the landscape is doing a producing metrics of interest – e.g. producing metrics of interest – e.g. carbon sequestration, habitat carbon sequestration, habitat production, land availability, risk, ???production, land availability, risk, ???
