The Forest Vegetation Simulator (FVS) is a tree-level, spatially non-explicit growth model. It is an outgrowth of the Stand Prognosis model that the U.S. Forest Service began developing in the late 1960s. Local variants of FVS now cover most of the forest types of the United States. Development of two complementary programs, Suppose and the Stand Visualization System (SVS), have opened the possibilities for using FVS as a teaching tool in forestry classes.
