Washington’s forest resources, 2007–2016: 10-year Forest Inventory and Analysis report

Informally Refereed

Abstract

The Forest Inventory and Analysis (FIA) program reports on the status and trends of Washington’s forest resources, producing comprehensive updates every 5 years. This report provides detailed estimates of forest area, tree species composition and distribution, volume, biomass, carbon, standing dead trees and down wood, and understory vegetation on forest land for the state of Washington. It also includes estimates of annual growth, mortality, and removals on forest land. Estimates are based on inventory data collected on 6,112 forested FIA plots in Washington between 2007 and 2016. There are 22.5 million forested acres in Washington covering about half the state’s land area. Washington has 9.4 billion live trees on forest land that collectively represent 94.3 billion ft3 of net volume or 853.3 million Mg of carbon. The majority of this forest volume occurs on the moist west side of the state. Net change in volume on forest land was positive for all ownership groups in western Washington, but negative on National Forest System lands in eastern Washington, especially in wilderness areas. Statewide, net change in volume was 20 ft3 ac-1 yr-1 or a total addition to net volume of 415 million ft3 yr-1.
