The following mortality and removals queries are returning incorrect summaries in EVALIDator.

  • Average annual mortality of growing-stock trees (at least 5 inches d.b.h.), in cubic feet, on forest land
  • Average annual harvest removals of growing-stock trees (at least 5 inches d.b.h.), in cubic feet, on forest land
  • Average annual other removals of sawtimber trees, in board feet (International 1/4-inch rule), on forest land
  • Average annual other removals of sawtimber trees, in board feet (International 1/4-inch rule), on timberland

In addition the ratio estimate option (i.e. the option to choose a denominator) is returning incorrect estimates for any ratio involving net growth, mortality, or removals on timberland. Ratio estimates involving net growth, mortality, or removals on forest land are working correctly. Ratio estimates are intended to be restricted to timberland-to-timberland or forest land-to-forest land observations but the restriction is currently malfunctioning for timberland-to-timberland observations.

We are working to correct the problem and will update the alert when it has been corrected.

We are sorry for the inconvenience.

FIDO is working properly.

  • FIADB has been updated to include the new updated interpretation of the definition of reserved status. All annual data has been reanalyzed in accordance with this interpretation and some previously published values have changed as a result. Change estimates have been recomputed to account for any modifications. For more details please consult the FIADB User Guide (http://www.fia.fs.fed.us/library/database-documentation/).

  • Welcome to our site

    We are the Nation's Forest Census


    The Forest Inventory and Analysis (FIA) Program of the U.S. Forest Service provides the information needed to assess America's forests.

    As the Nation's continuous forest census, our program projects how forests are likely to appear 10 to 50 years from now. This enables us to evaluate whether current forest management practices are sustainable in the long run and to assess whether current policies will allow the next generation to enjoy America's forests as we do today.

    FIA reports on  status and trends in forest area and location; in the species, size, and health of trees; in total tree growth, mortality, and removals by harvest;  in wood production and utilization rates by various products; and in forest land ownership.

    The Forest Service has significantly enhanced the FIA program by changing from a periodic survey to an annual survey, by increasing our capacity to analyze and publish data, and by expanding the scope of our data collection to include soil, under story vegetation, tree crown conditions, coarse woody debris, and lichen community composition on a subsample of our plots.

    FIA is managed by the Research and Development organization within the USDA Forest Service in cooperation with State and Private Forestry and National Forest Systems. FIA traces it's origin back to the McSweeney - McNary Forest Research Act of 1928 (P.L. 70-466). This law initiated the first inventories starting in 1930.
