FIA, in conjunction with the Forest Service Chief Information Office, will be implementing changes to the FIADB structure and data the third and fourth weeks of April. During that time, FIADB and the online tools will remain available; however, the data will consist of a mix of version 5.1 and 6.0 data. The most visible change is in the interpretation of the definition of reserved status. All annual data have been reanalyzed in accordance with this interpretation and some previously published values have been changed. Change estimates have been recomputed to account for any modifications. For more details please consult the FIADB User's Guide (http://www.fia.fs.fed.us/library/database-documentation/).
For more information contact any of the following:
We expect to correct this problem by late April 2014. Thank you for your patience. Please check here for further information and updates.

We have discovered an issue in our calculation of sampling error estimates. Currently, sampling error estimates in EVALIDator are only valid when “trend analysis” is selected as the row variable. Population totals and ratio estimates from EVALIDator are valid and are not affected by this error. Estimates from FIDO are not affected.
We expect to correct this problem by late April 2014.
Thank you for your patience. Please check here for further information and updates.
FIADB 5.1.6 - has been released. You may notice changes in FIADB tables, FIDO, EVALIDator and the DataMart. Some new tables may not contain data until the 2012 field data are processed.
