User Alert:

January 4, 2017: FIDO is not able to be accessed from outside the Forest Service at this time due to security configuration files. We are working with the Chief Information Office to resolve the issue.

October 20, 2016: New Tool Available! The Design and Analysis Toolkit for Inventory and Monitoring, DATIM, is available.

January 8, 2016: FIDO's Standard Reports is no longer being maintained. If you are experiencing issues, please use the custom reporting tool instead. FIDO's Standard Report option will be discontinued upon future release.

For FIDO, EVALIDator and the DataMart users wishing to know what has recently become available see this page: http://apps.fs.fed.us/fiadb-downloads/images/recent_load_history.html

September 22, 2015: The EVALIDator is unable to produce estimates of growth, removals and mortality for multiple inventories when "Trend analysis" is chosen as the row classification variable and the inventories chosen have different sampling designs (i.e., a mix of periodic and annual inventories). In the event that a user inadvertently runs such a retrieval the EVALIDator will return zeroes for the periodic inventories and the correct numbers for the annual inventories. We are sorry for any inconvenience.

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. The FIA program has also expanded to include the sampling of urban trees on all land use types in select cities.

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.
