The Forest Inventory and Analysis Database: Database Description and Users Manual Version 5.1 for Phase 2

Version 5.1 of the FIADB users manual was released in November, 2011 (document header date is October, 2011). This document describes all core measurements (and some optional core elements) collected on Phase 2 plots (the standard base FIA sample grid, 1 sample location per roughly 6,000 acres). Because of a change in field procedures that resulted in a field guide version 5.1, the FIADB version released after 4.0 is 5.1, with no version 5.0.

The FIADB Users Manual is distributed electronically as a .pdf files.

Three files are available, the full document, the document without the appendices, and just the appendices.
