A Grand Plan for FIA’s role

in a FS National Carbon Accounting SystemLinda S. HeathUSDA Forest ServiceNorthern Research Station, FIAForest Carbon Accounting and ResearchDurham, NH

SUMMARY POINTS

Carbon stocks and CO2 change Intensive-site measurements

needed for overall FS C System TPO/Utilization studies—Fate of

carbon is keyt

Some accomplishments thus far..

FIA-based estimates have been gold standard for forest carbon for over a decade in the US --policy use, science community

Sustainability report, Heinz Center reports, Paper in Science (by Pacala et al.), Voluntary Reporting Program update, GHG inventories

Carbon Tools Web Pagenrs.fs.fed.us/carbon/tools--Carbon Calculator Tool--FORCARB2

National GHG reporting to UNFCCC

•Annual Greenhouse Gas (GHG) Emissions and Sinks (1990-present) – US EPA

•Every 5 years, summary national communication- State Dept.•USDA biennial

Guidance for GHG inventories evolves

Intergovernmental Panel on Climate Change (IPCC) Guidelines for National Greenhouse Gas Emissions and Sinks (1994-1996)

IPCC Good Practice Guidance for Land Use, Land Use Change and Forestry (2001-2003)

Primary equations

Carbon stock = area x carbon/area

CO2 change =

((Stock(t2)– Stock (t1))/(t2-t1))*3.66

Forest carbon stocks AND CO2 change (dynamics) are needed

Carbon per acre, all forest pools

Change in C over time for GHG inventories (CO2 equivalents – CO2eq)

Area of forest, change in area of forest

10

C stocks per hectare by county

Flux data typically calculated at 30-minute intervals but aggregated to daily, monthly or annual values

Measurements from intensive-site techniques are

essential--Provides interannual variability

(for a “footprint” around tower)

--Soil and forest floor flux

--Per Acre Differences

System boundaries are key

National program goals for FIA

To conduct strategic forest inventories of the United States to estimate:

• extent of forest land

• volume, growth, and removal of forest resources; and

•health and condition of the forest

Competitive advantages for FIA

We are the nation’s forest censusData on carbon stocks Focused on data and “users”Technical expertise in measurements and math

What about the science community?

FIA and the Science Community

--FIA is in the R&D branch of the FS

--FS R&D personnel are covered under the FS Code of Scientific Ethics when conducting research

Priority improvements

/Carbon estimates based on P3 data are documented and made available in tools and datasets

/Biomass equations -- US wide sampling for biomass data, conducted w/ utilization studies?

/Land Use-Land Cover and Change
