Outline l.jpg
Outline

  • Carbon stocks

  • What are FIA data?

    --focus on annualized survey

    --not only carbon per area but also area

    --what about after the forest?

    --basis for text, tabular, graphs…maps?

  • Prospects for the near future

    --foundation for the ultimate carbon observation system!?


Net c sequestration land use change and forestry for the united states l.jpg
Net C sequestration, Land Use Change and Forestry for the United States

Forests offset >10% of

all emissions

Forests, urban forests, and

wood burned for energy offset

18% of fossil fuel emissions

Fire emissions?

(all are net sinks, no non-CO2)


National program goals for fia l.jpg

United Statesextent of forest land

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

•health and condition of the forest.

National program goals for FIA

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


Slide6 l.jpg

Over 300 million hectares of forest – 4 United Statesth most forested nation in the world

Geographic span of FIA

From the Artic Circle to the

Tropic of Capricorn.

From the Virgin Islands to Palau, west of Sidney

Fast Fact: FIA operates in 12 different time zones

Ground data becoming available from most of island

territories—starting again in Hawaii—southeast AK


Slide7 l.jpg

What kind of FIA data can inform the carbon debate? United States

  • Phase 2 - forest mensuration

  • -- 1 plot per 6000 acres

  • -- visit plot every 5 years

  • Phase 3 – forest health

  • -- each 16th P2 plot

  • -- soils, forest floor, down woody nationally

  • -- 1 plot per 96,000 acres

  • -- soils sampled every 2nd visit

  • Phase 1 – remote sensing

  • -- reduce variance through stratification


Slide8 l.jpg

What kind of FIA data (continued)? United States

  • Harvested wood & products

  • --Utilization Studies

  • --Timber Products Output

  • Ownership survey

  • National Inventory & Monitoring Applications Center



Sampling frame where locate plots l.jpg
Sampling frame –where locate plots? United States

  • Adopted hexagonal sampling frame

  • Shape allows plots to be equidistant

  • Shape allows for further tessellation

For US:

-- 125,000 forested P2 plots

-- 7,800 P3 plots

State of Minnesota, P2/P3 grid

FIA typically produces reports that include textual, tabular, and graphical descriptions of the forest resource…


Slide12 l.jpg

But what about maps? tabular, and graphical descriptions of the forest resource…

Carbon stocks per hectare by county

Includes all forest ecosystem carbon components, based on FORCARB2 and 2002 RPA Forest Data


Maps from fia data other data and models l.jpg

  • Cubist&NLCD

  • (Blackard et al 2008)

  • Some others:

  • Landsat

  • (Cohen et al)

  • MODIS

  • (Wilson et al)

Soon will be many maps….

National inventory monitoring applications center nimac in fia l.jpg
National Inventory & Monitoring Applications Center (NIMAC) -- in FIA

Mission: To develop forest ecosystem inventory and monitoring methods and tools to help FIA and other organizations monitor forests, producing comparable results across the landscape.

Examples:

Eastern National Forests: using planning tool

Natl Forest in Missouri: 2X P2 sample and 7X P3

Wisconsin DNR: monitoring 500,000 ac State Forests

Indiana DNR: monitoring 150,000 ac State Forests

Summary…for now -- in FIA

  • FIA Data:

  • Poised to be a foundation

  • --carbon stocks, stock change, carbon fate beyond forests, land use change

  •  Data are being collected annually

  •  Documentation, analysis, data delivery system needs time to catch up

  •  Data integration/fusion with RS techniques and modeling produce even more useful results
