Green button, thumb drive with the FVS logo on it.

Obtain Forest Vegetation Simulator (FVS) software at the Complete Package or Components links below. We suggest checking the FVS software pages often. FVS software changes as needs arise to improve the models and programs. We recommend bookmarking this web page for future reference. You will need forest inventory or stand examination data to run FVS.

Complete Package

The FVS Software Setup file covers all Regions of the National Forest System. It includes the graphical user interface (Suppose), FVS Variant files, and post-processing programs including the Stand Visualization System (SVS), sample data, and exercise workbooks in a single, easy-to-install utility.

FVS Source Code

The FVS source code is available through the "open-fvs" project. See the Downloading Source Code page on the open-fvs Wiki for information about using an SVN client to download the FVS source files. There are also instructions on the Wiki for building FVS executable files using several different tools.
