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.
Note - Alaska field crews used the Coastal Alaska field guide plus an Interior Alaska supplement through the 2018 field season. In 2019 the Alaska inventory field guides were combined.
