Various disturbance processes affect the sustainability of forest attributes and outputs in the U.S. West. These processes include fire, insects, disease, and weather. We used 172,472 Forest Inventory and Analysis (FIA) plots (49,715 forested plots) measured between 2001 and 2015 from the states of AZ, CA, CO, ID, KS, MT, ND, NE, NM, NV, OR, SD, UT, WA, WY, and southeast Alaska to evaluate the amount and type of recent disturbance affecting western U.S. forests. Natural and human-caused disturbances affected 57.8 million forested acres in these states within a five year window, or 22.3% of all forest land. The most common types of disturbance recorded were disease and insects, each estimated as impacting 15.0 million acres. Human disturbance (including silvicultural management) affected 10.8 million acres, while grazing and animal damage affected 9.6 million acres. While fire may be the most costly disturbance, it was only the fifth most prevalent in terms of spatial extent, affecting 9.1 million acres. We discuss how results compare to other monitoring methods, and how these data can be used to understand longer-term trends and impacts on sustainability.
