The USDA Forest Service, Forest Inventory and Analysis (FIA) program has been in continuous operation for over 70 years. FIA’s primary objective is to determine the extent, condition, volume, growth, and depletion of timber on the Nation’s forest land. To accomplish this objective, FIA collects sample plot information on all ownerships across the United States.
The Forest Inventory and Analysis Database (FIADB) (Miles and others 2001), was developed to provide users with a nationally consistent format for FIA data. FIADB files can be obtained for any State inventory conducted after 1988 for the Eastern United States or 1994 for the Western United States. All data in FIADB format can be exported into FVS-ready files for use in the Forest Vegetation Simulator (FVS) program. The FIA program is working with a variety of cooperators to develop alternative pathways for delivering FIA data to FVS users.
