Forest Monitoring and Assessment
We conduct fundamental and applied research to understand and predict changes in forest landscapes across all ownerships. We develop innovative techniques for long-term monitoring, detecting change, and predicting outcomes following forest management and disturbances.
Program Overview
The Forest Monitoring and Assessment (FMA) program helps to inform the consequences of decisions made that affect landscapes and ecosystem services, like water, recreation, and forest products. Our data and research are used to gauge progress toward forest restoration, the effects of disturbance and climate on forests, and help people understand how forests are changing through time. We measure forests in Alaska, California, Hawaii, Oregon, Washington, and the U.S.-affiliated Pacific Islands to provide the public, land managers, investors, and policy makers with timely, reliable, data-driven science to improve the condition of forests and rangelands. The inventory and monitoring component of FMA is part of a larger, national Forest Inventory and Analysis (FIA) program. The Pacific Northwest FIA (PNW-FIA) program provides data and basic resource information needed to assess the current status and potential futures of America's forests.

The Forest Monitoring and Assessment (FMA) program provides science and technical applications that can be readily used by land managers and decisionmakers to improve the quality of life for people in the Pacific Northwest, the Nation, and the world.
Our research focuses on landscape assessment, management, partnerships, as well as delivery of science and technology through education and outreach. The FMA program addresses current and future natural resource issues with applied research that produces tools that are of use to on-the-ground natural resource specialists and others. FMA scientists are based at the Forestry Sciences Laboratories in Anchorage, Corvallis, Portland, Olympia, and Seattle, but team scientists and staff conduct research projects across the range of Pacific Northwest (PNW)-FIA states (Alaska, California, Hawaii and the U.S.-affiliated Pacific Islands, Oregon, and Washington), as well as on topics that are national and international in scope.
The Vegetation Monitoring Science and Application (VeMSA) team develops and applies comprehensive, regional-scale resource information to improve the management and understanding of forests and rangelands. Most of the team's research is focused on improving monitoring techniques and developing new applications for the Forest Inventory and Analysis Program (FIA).
The Vegetation Monitoring and Remote Sensing (VMaRS) team uses state-of-the-art geospatial technologies with traditional forest inventory information to increase the accuracy and precision of resource monitoring systems over multiple spatial scales. Application of remote sensing can increase the efficiency of monitoring and enable near-term detection of changes in the condition of aquatic, riparian, and terrestrial ecosystems affected by management and natural disturbance. Research conducted by VMaRS scientists consists of a range of activities, from very focused and detailed explorations of narrowly defined problems to broad descriptions of vegetation and change processes and ecological consequences across large spatial scales.

The Pacific Northwest Forest Inventory and Analysis (PNW-FIA) program measures and compiles data on plots in Alaska, California, Hawaii, Oregon, Washington, and U.S.- affiliated Pacific Islands. Most data are available in SQLite databases and can be downloaded by clicking one of the links below.
Current data summaries for each state can be found on our State Stats page.
PNW-FIADB (Forest Inventory and Analysis Database): annual data for California, Oregon, Washington, and Alaska beginning in 2001.
PNW-FIA Hawaii Inventory Database
PNW-FIA Pacific Islands Inventory Database
National FIA Data and Documentation
PNW-FIA data are combined with data from all states in the U.S. and stored in the national FIADB. Data for any state can be accessed on the national FIA Data and Tools website. Raw data are available via the FIA Data Mart and table generator tools such as EVALIDator provide a user-friendly interface for producing quick, customizable data summaries. The national FIADB User Guide provides comprehensive information on all fields in the database and is a good place to start when using the data.
Field Manuals
Detailed field manuals for each inventory and year and available on the PNW-FIA Field Manuals page.
Prior PNW-FIA Inventories
The PNW-FIA Program shifted from a periodic to an annual inventory system in 2001. Periodic inventories sampled primarily timberland plots outside of national forests and most reserved areas, in a single state within a 2- or 3-year window. Typically, re-assessments occurred every ten years in the West. For the annual inventory in the Pacific Northwest all forested plots are now sampled, with one-tenth of the plots in any given state being visited annually. A full annual inventory cycle is complete in ten years.
PNW-IDB Periodic Inventory Database
Pacific Northwest Forest Inventory and Analysis (PNW-FIA) measures and reports on forest conditions in coastal Alaska, California, Hawaii, Oregon, Washington, and U.S.-affiliated Pacific Islands.
The PNW-FIA Field Manuals used for field data collection by the PNW-FIA region include detailed instructions for both core (nationally consistent) and regional data items. Manuals for annual inventory of California/Oregon/Washington, annual inventory of coastal Alaska, Interior Alaska, Pacific Islands, special studies, and historic (periodic) inventories and can be found in the sections below.
National FIA field manuals and FIADB database documentation can be found on the national FIA website. These documents contain all items which are collected consistently across all 50 states and U.S. territories, and they serve as the basis for each of the regional manuals listed below.
