  • The distribution of net ecosystem production (mean for 2006–2010). Areas in red denote highest productivity and therefore sequestered the greatest amounts of atmospheric carbon.
    Forest land across four-state region was a net carbon sink during 2006–2010

    Variation in climate, disturbance regime, and forest management strongly influence terrestrial carbon...

The Resource Monitoring and Assessment (RMA) program helps to inform the consequences of decisions made that affect landscapes and ecosystem services, like water, recreation, and forest products. Our data and research are used to gauge progress toward forest restoration, the effects of disturbance and climate on forests, and help people understand how forests are changing through time. We measure forests in Alaska, California, Hawaii, Oregon, Washington, and the U.S.-affiliated Pacific Islands to provide the public, land managers, investors, and policy makers with timely, reliable, data-driven science to improve the condition of forests and rangelands.

The inventory and monitoring component of RMA is part of a larger, national Forest Inventory and Analysis (FIA) program. The Pacific Northwest FIA (PNW-FIA) program provides data and basic resource information needed to assess the current status and potential futures of America's forests.
