FIA 5-year report summarizes forest conditions in Washington
Forest Service scientists summarized and interpreted basic information about public and private forest land in Washington State. Topics include land use change, ownership, timber volume, biomass and carbon stocks, biodiversity, insects and diseases, invasive plants, air pollution, and more. This report, based on data from 2002 through 2006, establishes a baseline against which future conditions can be compared and trends can be identified. This information is useful to state and federal agencies and private firms.
The authors identified several key findings in the report. They found that Washington's forests are presently a net sink for carbon, whereas most timber production is coming from private lands. Nonnative invasive plant species already are well established in Washington's forests, covering 4 percent of all forest land on average. They also found lichen communities indicative of nitrogen pollution in forests west of the Cascade Range, particularly in the Puget Trough ecoregion, which runs the length of the state along the Interstate-5 corridor.
