First datasets for U.S. "National Biomass and Carbon Dataset" now available; useful tool for bioenergy sector
Scientists at the Woods Hole Research Center working to produce America's "National Biomass and Carbon Dataset" for the year 2000 (NBCD2000) are releasing data from nine project mapping zones. All NBCD2000 data products are being made available for download on a zone-by-zone basis and free of charge from the NBCD2000 project website. The datasets are of interest to natural resource managers, especially those in silviculture and the bioenergy sector.
Through a combination of NASA satellite datasets, topographic survey data, land use/land cover information, and extensive forest inventory data collected by the USDA Forest Service - Forest Inventory and Analysis Program (FIA), NBCD2000 will provide an invaluable baseline for quantifying the carbon stock in U.S. forests and will improve current methods of assessing the carbon flux between forests and the atmosphere.

Wayne Walker, a research associate at the Center who is also working on the project adds, that the data sets that are now available should be of interest to natural resource managers across the U.S. For the first time, high resolution estimates of vegetation canopy height and biomass are being produced consistently for the entire conterminous U.S.
Within each mapping zone data from the 2000 Shuttle Radar Topography Mission are combined with topographic survey data from the National Elevation Dataset (NED) to produce a radar-based map of vegetation canopy height. Subsequently, the map is used to generate estimates of actual vegetation height, biomass, and carbon stock using survey data from the U.S. Forest Service - FIA program and ancillary data sets from the National Land Cover Database 2001 (NLCD2001) project.
The NLCD2001 data layers are crucial inputs to the NBCD2000 project as they provide land cover and canopy density information used in the stratification/calibration process.
Because this is the first systematic, regional-scale study that uses radar data to quantify carbon storage in vegetation, the end result will not only provide valuable information on how well we can do with existing data, but will allow us to see how we might improve and refine requirements for future, more capable missions like DESDynI, which has been recommended by the National Research Council Decadal Survey on Earth Observation. - Diane Wickland, program manager for NASA's Terrestrial Ecology Program
The project website will be updated regularly as mapping zones are completed.
Forest resources and bioenergy
State forest services across the U.S. have been launching initiatives to tap forest resources as a source of bioenergy that can help overcome serious risks, including forest fires. Forest residues as a feedstock for cellulosic ethanol were left out of the recently approved Energy Bill, which requires 21 billion gallons of ethanol to be produced from biomass, including cellulosic materials, by the year 2022.
The provision doesn't limit using wood waste from national forests but it will not count toward the increased renewable fuels standard target in the energy bill. There is one exception in the definition: biomass from federal forests in the immediate vicinity of private homes qualifies for the renewable fuels standard. Several forestry services and policy makers have expressed their dissatisfaction with this measure and have stepped up efforts to get forestry residues included under the RFS.
A joint study by the US Departments of Agriculture and Energy (USDA and DOE) earlier concluded - in a report titled Biomass as Feedstock for a Bioenergy and Bioproducts Industry: The Technical Feasibility of a Billion-Ton Annual Supply - that the land resources of the US could produce a sustainable supply of biomass sufficient to displace 30% or more of the country’s present petroleum consumption.
The study found that just forestland and agricultural land alone have a potential for 1.3 billion dry tons of biomass feedstock per year: 368 million dry tons from forestlands, 998 million dry tons from agriculture (table, click to enlarge).
The Woods Hole Research Center is dedicated to science, education and public policy for a habitable Earth, seeking to conserve and sustain forests, soils, water, and energy by demonstrating their value to human health and economic prosperity. The Center has initiatives in the Amazon, the Arctic, Africa, Russia, Asia, Boreal North America, the Mid-Atlantic, and New England including Cape Cod. Center programs focus on the global carbon cycle, forest function, landcover/land use, water cycles and chemicals in the environment, science in public affairs, and education, providing primary data and enabling better appraisals of the trends in forests.

The availability of a high resolution dataset containing estimates of forest biomass and associated carbon stock is an important step forward in enabling researchers to better understand the North American carbon balance. - Dr. Josef Kellndorfer, project leaderAs part of the NBCD2000 initiative, begun in 2005 and funded by NASA's Earth Science Program with additional support from the USGS/LANDFIRE, mapping is being conducted within 67 ecologically diverse regions, termed "mapping zones", which span the conterminous United States. Of the nine completed zones, 5 were finished during a 2-year pilot phase. Work on the remaining zones will be completed at a rate of roughly one zone every seven days. The project is scheduled for completion in early 2009:
