Database Documentation

The FIADB 6.0.1 Phase 2 and Phase 3 user guides are now available. These documents describe all variables available in the FIA database. The P2 data represent plot, condition, and tree measurements taken on the standard FIA base grid, which is roughly 1 sample location per 6,000 acres. P3 data are the forest health indicator measurements taken on a subset of the P2 plots, roughly 1 sample location per 90,000 acres.


The FIADB user guide format has been revised. Each chapter is now numbered independently with a revision date on each page. This will make it possible for users to print specific chapters of interest, or in the future, only revised chapters. Please see the chapter titled User Guide Updates for complete information about the new format.
