Database Documentation

The FIADB 5.1.6 Phase 2 user manual was released in June, 2013, but the file is dated July 12, 2013. The Phase 3 user manual version 5.1.4 is still valid. 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.
