  Carbon dynamics research initiative opens new pathways to discovery

  Urgency is growing among legislators, conservation organizations, and the wood products industry to better understand how forests store carbon and how management choices affect the carbon balance. The Pacific Northwest Research Station is taking a convening role with states and nongovernmental organizations to address research needs across stewardship boundaries.

  A Carbon Accounting Framework for Oregon

  How much carbon do Oregon’s forests sequester each year? An amount equivalent to the annual emissions from 6.6 million passenger vehicles, give or take 1.6 million cars. Between 2001 and 2016, Oregon’s forests functioned as a net sink of carbon, with stores increasing at a rate of 30.9 ± 7.4 million metric tons of carbon dioxide equivalent per year.

  Working with Cal Fire to monitor carbon sequestration in California

  Forest Service scientists partnered with California’s Department of Forestry and Fire Protection (Cal Fire) to develop a carbon inventory essential for assessing the state’s progress toward meeting its carbon sequestration target via California’s forest sector. They found that California forests are exceeding the target rate of annual sequestration.

  How much logging residue is left behind?

  Logging utilization studies quantify the amount of logging residue generated by commercial timber harvests. Last conducted in the 1980s, updated studies were needed for Oregon and Washington to reflect current harvesting practices.

  New report analyzes change in California's forest-products industry and timber harvest; 2006-2012

  The Forest Inventory and Analysis program includes regular production of statewide assessments of timber-products outputs. These studies trace the flow of a state's timber harvest through the primary wood-products industry and provide a description of the structure; condition; and economic impacts of the forest products sector. Historical trends also are discussed.
