The Forest Vegetation Simulator (FVS) is a forest growth and yield model developed by the United States Forest Service and is used by natural resource managers and researchers. FVS is calibrated for specific geographic areas and uses a host of simulation models to forecast forest composition and structure.
DGVMs generally combine biogeochemistry, biogeography, and disturbance submodels.Disturbance is often limited to wildfires, but in principle could include any of: forest/land management decisions, windthrow, insect damage, ozone damage etc. DGVMs usually "spin up" their simulations from bare ground to equilibrium vegetation (e.g. climax community) to establish realistic initial values for ...

The system provides clear definitions and codes for recording plant distributions at four scales or levels, from "botanical continents" down to parts of large countries. Current users of the system include the International Union for Conservation of Nature (IUCN), and the Germplasm Resources Information Network (GRIN). [ 1 ]

The model considers transient changes in vegetation composition and structure in response to environmental change and is, therefore, classified as a Dynamic Global Vegetation Model [2] This new version of IBIS has improved representations of land surface physics, plant physiology, canopy phenology, plant functional type (PFT) differences, and carbon allocation.
The stages can be characterized by Structural Stage categories, e.g., young forest, or by their Successional Status, e.g., maturing seral. The developing vegetation can also be classified into seral plant associations (designated with $ sign). Note: Tree species codes are: Cw = western redcedar; Hw = western hemlock; Pl = lodgepole pine.
Vegetation classification is the process of classifying and mapping the vegetation over an area of the Earth's surface. Vegetation classification is often performed by state based agencies as part of land use, resource and environmental management. Many different methods of vegetation classification have been used.
