User Alert:

October 29, 2015: FIDO's Standard Reports option is not functional for some users due to an internet browser configuration conflict. We have developed a solution and are working with the CIO to deploy it. Custom Reports are not affected by this issue. Thank you for your patience.

September 22, 2015: FIA's DataMart is experiencing problems due to updates to Forest Service servers. The comma-delimited files are fine. The MS-Access files have no data.The Forest Service CIO and FIA are working together to solve this problem. Please check back here for updates. We apologize for any inconvenience.

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.

FIADB was updated in June 2014 to include the new updated interpretation of the definition of reserved status. All annual data was reanalyzed in accordance with this interpretation and some previously published values have changed as a result. Change estimates were recomputed to account for any modifications. For more details please consult the FIADB User Guide (
