Forest Inventory and Analysis is a consistent, national monitoring program covering all forest ownerships. We work with land managers as partners to provide a wealth of data that crosses management boundaries, just as disturbance, climatic events, and forest changes span boundaries. Together we answer questions to help sustain our forests and the communities that depend on them:
Interior Alaska Inventory
In 2017 the second full season of the Interior Alaska Forest Inventory & Analysis project was launched by the PNW Research Station’s Forestry Sciences Laboratory in Anchorage, Alaska, in collaboration with the State of Alaska Department of Natural Resources, Division of Forestry, and NASA. This new project will inventory the remaining 15 percent of U.S. forested land not yet covered in the FIA sample. The Interior Alaska effort will install about 4,500 new FIA plots on the ground over 12-15 years and supplement this data utilizing cutting edge remote sensing techniques (NASA’s G-LiHT system) before moving into the re-measurement phase.
Forest Inventory and Analysis (FIA) is a national program of the U.S. Forest Service that monitors forest resources on all lands – public, private, and tribal. FIA monitors forests in all 50 states, including southeast Alaska, but only 16 percent (15 million acres) of Alaska’s forests statewide have been included in this effort until now. At more than 600 million square miles, Alaska is the largest state in the U.S. The state’s interior boreal forests, spanning more than 170,000 square miles, are equally vast; representing 15 percent of total U.S. forestland. Although these forests play a significant role in supplying natural resources to local Alaskan communities and in sustaining global energy, water, and carbon cycles, they were not previously inventoried as part of the FIA program, making them the last U.S. forest type to be formally inventoried.

Inventory methods consist of standard Phase 2 FIA protocols with enhanced vegetation, lichen and moss ground cover, soils and tree ring measurements specific to the boreal forests of Interior Alaska. PNW RMA scientists continue to cooperate with NASA and the next generation of Goddard’s LiDAR, Hyperspectral and Thermal Imager (G-LiHT). The G-LiHT sensor suite enables integration with field data acquisition for model assisted landscape classification and vegetation attribute estimation like forest biomass and carbon sequestration.
