  1. An Improved Volume, Biomass and Carbon Database for U.S. Tree Species Greg Reams National Program Leader, FIA USDA Forest Service 2012 FIA National Users’ Group Meeting Baltimore, MD

  2. BACKGROUND • Provide a national standard for tree volume, biomass and carbon. • Unfortunately, biomass and carbon prediction methods requires destructive sampling to weigh various portions of the tree. • Each regional FIA unit has a representative to work with strategic constituents and university partners. • Working with key university partners with science expertise • Oregon State, Virginia Tech, University of Georgia, University of Maine, Michigan State, and University of Montana. • Working with strategic constituents to understand needs • National Forest System-Forest Management Service Center • Forest Industry-NCASI, Rayonier, Weyerhaeuser • Meeting (Oct. 2011) in Portland, ME to concentrate on three items. • Gap analyses • Scientific outputs • Sampling protocols

  3. Better has no Cheaper Equivalent • Volume and weight/carbon of trees were estimated in different ways within a FIA unit and across units. • Lack of fundamental volume to weight data the reason. • Volume emphasis…….biomass and carbon relationships to volume assumed • This has led to numerous estimation methods and published results • WE NEEDTHE FOUNDATIONAL DATA SO WE ARE NOT HAVING THE “My favorite volume and biomass equation or relationship discussion”. AGREE TO A NATIONAL STANDARD……

  4. Make it Clear What is Measured Tree component diagram based on Harold Young Ref Description 1 Small roots 2 Medium roots 3 Large roots 4a Stump above ground level 4b Stump below ground 5 Bole to a 4" top (10cm) 6 Large branches 7a Small branches 7b Leaves or needles 8 Central stem above 4" top

  5. Current Status • Gap Analyses: • Review relevant science to address knowledge gaps • Review standards, protocols and sample design of existing biomass and volume studies. • Focus on selected species, concentrate of top 10 species in North, South and West for a total of 30 species. • Use reviews to refine ideal sampling design and protocols. • Sampling design and protocols. • Felled tree studies • Standing tree studies • Utilization studies • Scientific outputs and publications. • Describe issues and challenges related to biomass sampling • Publication and use of individual tree species models for volume, weight and carbon.

  6. Three Year Plan • Year one-- gap analysis and sampling protocols for felled tree, standing tree and utilization studies. • Field demo in Knoxville, TN on February 28-29 to understand felled tree measurements at utilization site. • Leverage current tree taper measurements, product utilization and volume measurements. • Understand what additional measurements can be implemented at utilization sites to augment felled tree. • Year two and three– implement sampling standards and protocols nationwide. • Mix of felled tree, utilization felled tree, and standing tree studies. How many species, samples and mix dependent on available funds and willing participants. • Year three +-- Model fitting and continue field sampling

  7. Time and Costs Are An Issue • The desired target is 100 trees per species • For the top 10 species by three regions of the country • Felled tree studies are expensive yet vital to estimating weight of a tree and the trees component parts. • Standing tree studies are less expensive but depend on understanding fundamental relationships that can only be understood through felled tree studies. • Standing tree measures, Drop trees, cut and limb trees, taper measurement of bole and major limbs, weight of tree and components, cut disk for specific gravity lab work, LABOR & SAFETY commitments are substantial. • Our team of scientist from FIA, the six partner universities and NGOs estimate that it will cost $1 million per year for 3 years……Total of $3 million • FIA currently has a gap in available funding and needs.

  8. Topics for Discussion • Where does improved estimation of volume, biomass and carbon fall out on your FIA priority needs? • Based on prior discussions related to biomass, carbon and bio-energy development we are attempting to balance how best to produce the next-generation biomass data and model estimation. • We’re looking forward to your comments.
