Part 1

• Review of the state forest carbon inventory and
  forecast

5

Forestry

• Data Sources
• Forest Carbon USFS Forest Inventory Analysis
  data from 2 cycles (1988-1996 2004)
• Land Use/Cover Change FIA data used in FORCARB
  analysis USDA NRI 1982-97 (recently updated)
  used for isolated analysis of land cover change
  effects
• WOODCARB forest products and waste estimates
• Methods
• Forestry USFS FORCARB2 carbon stock change model
  provides carbon pools for each FIA cycle
• WOODCARB adds wood products and waste flows
• NRI provides verification and refinement of FIA
  forest cover change
• Flux calculated for each pool based on difference
  in time between FIA cycles

8
Forestry

• Key Assumptions
• 1988-2004 trends representative of 2005-2020
  trends
• Key Uncertainties
• Effects of new markets, policies and
  environmental effects through 2020
• Scaling of wood products storage estimates to PA

9
FIA Data

• Estimation of statewide stocks and stock changes
  of forest ecosystem carbon from FIA inventory
  data
• Carbon stock (tons) Carbon/Area Area
• For example, 609 and 655 million tons carbon in
  biomass for the 1989 and 2004 inventories,
  respectively.
• Carbon change (tons/year)
• Difference between successive stocks divided by
  the interval between inventories, or
• Modeled, if specific growth information is
  available, such as biomass growth or soil
  respiration
• Projected forest carbon based on stock plus change

10
Part 2

• Potential state forestry carbon management options

11
Potential State Forestry Carbon Management Actions

• Refer to handout
• See updated categories and actions
• Identify any further missing actions and or
  categories
• Identify existing PA actions
• Identify next steps for rankings of priority
  actions

12
CMAG Next Steps - Forestry

• For to next CMAG meeting
• Suggest ranking of GHG potential, cost, other key
  issues
• Suggest priorities for analysis for catalog of
  state action
• Questions or suggested revisions of the forest
  carbon inventory and forecast

13
Adjorn

• Announcements?
• Next Forestry call to follow 10/23 CMAG meeting
