This publication is based on previous documentation of the nationally standardized Forest Inventory and Analysis database (Hansen and others 1992; Woudenberg and Farrenkopf 1995; Miles and others 2001). Documentation of the structure of the Forest Inventory and Analysis database (FIADB) for Phase 2 data, as well as codes and definitions, is provided. Examples for producing population level estimates are also presented. This database provides a consistent framework for storing forest inventory data across all ownerships for the entire United States. Forest Inventory and Analysis (FIA) is a continuing endeavor mandated by Congress in the Forest and Rangeland Renewable Resources Planning Act of 1974 and the McSweeney-McNary Forest Research Act of 1928. FIA's primary objective is to determine the extent, condition, volume, growth, and depletion of timber on the Nation's forest land. Before 1999, all inventories were conducted on a periodic basis. The passage of the 1998 Farm Bill requires FIA to collect data annually on plots within each State. This kind of up-to-date information is essential to frame realistic forest policies and programs. USDA Forest Service regional research stations are responsible for conducting these inventories and publishing summary reports for individual States. In addition to published reports, the Forest Service provides data collected in each inventory to those interested in further analysis. This report describes a standard format in which data can be obtained. This standard format, referred to as the Forest Inventory and Analysis Database (FIADB) structure, was developed to provide users with as much data as possible in a consistent manner among States. A number of inventories conducted prior to the implementation of the annual inventory are available in the FIADB. However, various data attributes may be empty or the items may have been collected or computed differently. Annual inventories use a common plot design and common data collection procedures nationwide, resulting in greater consistency among FIA work units than earlier inventories. Data field definitions note inconsistencies caused by different sampling designs and processing methods.

U.S. Forest Service Forest Inventory and Analysis (FIA) data are stored in the Forest Inventory and Analysis Database (FIADB). FIADB-Lite was developed to simplify the generation of forest statistics. An FIADB-Lite database can be used to generate estimates of forest land area and tree biomass, volume, growth, removals, and mortality. FIADB-Lite consists of five database tables: four tables currently in the FIADB (POP_EVAL_GRP, COND, TREE, and SEEDLING) that are described in the FIADB Users Guide Version 3.0 (Conkling, editor, draft), and one new table, PLOTSNAP

The PLOTSNAP table combines information from three FIADB tables (PLOT, POP_ EVAL_GRP, and POP_STRATUM) to provide a "snapshot" of the PLOT records and their associated expansion and adjustment factors that were used to produce a state inventory report. Combining information from these three tables greatly simplifies the procedures for generating forest statistics. Users needing associated sampling errors should use the entire FIADB rather than FIADB-Lite because calculation of variances requires information from additional tables. FIADB-Lite download files and an MS-Access database with stored Data Import Specifications and stored Queries for generating population estimates are available from the FIA national web site (www.fia.fs.fed.us) on the data download page.

Forest Inventory and Analysis (FIA) is a US Department of Agriculture Forest Service program that aims to monitor changes in forests across the US. FIA hosts one of the largest ecological datasets in the world, though its complexity limits access for many potential users. rFIA is an R package designed to simplify the estimation of forest attributes using data collected by the FIA Program. Specifically, rFIA improves access to the spatio-temporal estimation capacity of the FIA Database via space-time indexed summaries of forest variables within user-defined population boundaries. The package implements multiple design-based estimators, and has been validated against official estimates and sampling errors produced by the FIA Program. The package has been made open-source is freely available for download from the Comprehensive R Archive Network.In recent decades, forests of the western US have experienced unprecedented change in climate and forest disturbance regimes, and widespread shifts in forest composition, structure, and function are expected in response. However, large-scale, comprehensive assessments of tree population performance have yet to be conducted in the region. We develop an index of forest population performance based on repeated censuses of field plots, and apply this index to assess the status of the most abundant tree species in the western US. Our study provides empirical evidence to suggest tree species in the western US are exhibiting strong divergence in population performance, with over half (70%) of species experiencing range-wide population decline. We found spatial variation in population performance across the ranges of all species, indicating range shifts are already underway. Our results further indicate that species decline can seldom be attributed to a single forest disturbance agent, highlighting the importance of considering multiple risks factors in broad-scale forest management.
