3. F I A Forest Inventory and Analysis Program The Nation’s Forest Census Biomass estimation goals National consistency Biomass-volume compatibility in our national database Realistic estimates of any component for any selected area

4. F I A Forest Inventory and Analysis Program The Nation’s Forest Census FIA development of CRM CRM is the Component Ratio Method for calculating total biomass by tree component and is a modified version of the commonly used biomass expansion factor (BEF) approach relies on FIA individual tree measurements to estimate bole volume and missing and rotten material relies on published biomass studies to establish relationships between tree boles and other tree and site components

Total Forest Carbon Live above-ground carbon Dead wood carbon Forest floor carbon Live below-ground carbon Soil organic carbon Forest Carbon Pool Tables by State and Owner Group Forest Carbon Graphics Graphics Fact Sheet Forest Carbon Fact Sheet Carbon in U.S. Forests In an effort to provide further transparency and consistency in official U.S. forest carbon estimates, the FIA program of the U.S. Forest Service is now providing carbon stock estimates through a selection of our online tools. As we endeavor to improve national consistency of our carbon modeling and estimation procedures, there will be divergences between estimates from older procedures and newer estimates such as provided on this web page. As we progress through this continuous improvement process with our stakeholders, national consistency among carbon reporting tools and improved confidence in carbon estimates will be achieved.

11. F I A Forest Inventory and Analysis Program The Nation’s Forest Census Carbon Progress 1. IPCC annual carbon reported by FIA 2. Enhanced tree component reporting in FIADB 3. Basic estimates for all forest carbon pools 4. Units working on taper equations 5. Completion of CRM and Specific Gravity papers 6. Posted U.S. carbon by ecoregion to the web
