Pacific Northwest Forest Inventory and Analysis

National FIA Program

The Forest Inventory and Analysis (FIA) program is a national program within the U.S. Department of Agriculture Forest Service that provides information about America's forests. FIA has several components:
Forest Inventory – includes data collection in the field, data distribution, and analysis of that data.

Timber Products Output (TPO) Studies – used to estimate industrial and non-industrial uses of wood.

National Woodland Owner Survey – a survey of forest owners to determine owner characteristics and future plans for their land.

Resources Planning Act (RPA) – FIA provides data for a national assessment every 5 years as required by the Agriculture Research, Extension and Education Reform Act of 1998 (Farm Bill)

PNW-FIA Program

The Pacific Northwest Research Station (PNW) is one of five Forest Service Research Stations with an FIA program. It is our job to determine the extent and condition of forest resources and analyze how these resources change over time for all ownerships in Alaska, California, Hawaii, Oregon, Washington, and the US Pacific Territories. PNW-FIA has been in operation under various program names (Forest Survey; Inventory and Economics; Inventory, monitoring and Evaluation) for some 70 years. The program is implemented in cooperation with a variety of partners including state forestry agencies and private landowners who grant access to their lands for data collection purposes.

The PNW-FIA mission is to collect, compile, and make available high quality and comprehensive forest inventory data; and to provide summaries, interpretations, and research findings from that data.
