    • 1. Carbon Storage and Carbon Credits for Forest Management: The Good, the Bad, and the Ugly Mike Ryan USDA Forest Service Rocky Mountain Research Station Fort Collins, CO 80526 [email_address] http://lamar.colostate.edu/~mryan
    • 2. From SOCCR Report: http://www.climatescience.gov Why does the carbon cycle matter? CO 2 absorbs radiation from earth and warms it Rising CO 2 increases ocean acidity CO 2 was not higher than 280 ppm for > 400,000 years Rising CO 2 shows an imbalance between sources and sinks
    • 3. Global C Cycle
      • Reservoirs in plants and soil are similar to fossil fuels
      • Fluxes to and from plants and soil are large
      Fluxes – how much enters and how much leaves a pool per unit time Pools – how much C is in a given location
    • 4. From SOCCR Report: http://www.climatescience.gov US forests and long-lived wood products offset about 12-20% of fossil-fuel emissions North America Mt = (10 12 g) CCSP, 2007. The First State of the Carbon Cycle Report (SOCCR): The North American Carbon Budget and Implications for the Global Carbon Cycle .
    • 5. 10% is Huge!
      • To get another 10%:
      • Convert entire US auto fleet to hybrid gas mileage
      • Convert 1/3 current Ag land to forests.
    • 6. Why the Uncertainty?
      • SOCCR Report includes large estimates for carbon stored in soil (highly uncertain).
      • Woodbury et al (2007) has a much lower rate for carbon stored in soil.
    • 7. US Forest Carbon Balance 1800-1950: Forest Disturbance on a Massive Scale-the Industrial Revolution Birdsey, R., K. Pregitzer, and A. Lucier. 2006. Forest carbon management in the United States: 1600-2100. Journal of Environmental Quality 35:1461-1469. In 1915, emissions from forests were 760 million tons C per year Photo courtesy of University of Washington Libraries, Special Collections, KIN084. ?
    • 8. In 2000, sequestration by forests was ~200 million tons C per year US Forest Carbon Balance 1950 to 2008: Forest Regrowth on a Massive Scale Birdsey, R., K. Pregitzer, and A. Lucier. 2006. Forest carbon management in the United States: 1600-2100. Journal of Environmental Quality 35:1461-1469. Photo by Mike Ryan
    • 9. Forest carbon has a cycle: after disturbance, loss and recovery Photo by Mike Ryan Photo by Dan Kashian Photo by National Park Service Photo by Mike Ryan
    • 10. Ecosystems that regenerate forests after disturbance (harvesting, fire, bugs) will recover all of the carbon lost
    • 11. The larger the landscape, the more stable the carbon seems
    • 12. How Does Fire Change Forest Carbon? Fire kills trees, it doesn’t consume them; Fire losses of foliage and forest floor are only ~10-20% of the site carbon Photo by Dan Kashian Photo by AZ Dept Emergency Mgmt
    • 13. Fire would reduce carbon storage on the YNP landscape only if stand-replacing fires become much more frequent (return intervals < 50 yrs)
    • 14. What happens with no regeneration? Example: Hayman Fire, Colorado, 2002 Photo by Merrill Kaufmann, USFS
    • 15. Bottom line: After a fire, if a forest replaces itself, there is little net loss or gain of carbon over a fire cycle
    • 16. What about MPB Outbreak? Example: Colorado, 1998-? Photo by Merrill Kaufmann, USFS
    • 17. Forest Ecology – Bottom Line
      • Disturbance does not cause C loss, unless forest does not regenerate
      • Carbon is best evaluated over large scales of space and time
      • The timing isn’t important
      Photo by Mike Ryan
    • 18. Scale of the Problem
      • Our C emissions are ~ 2 Petagrams C/yr (10^15 g)/yr
      • For afforestation on cropland to take up another 10% of US emissions:
        • 44 million ha of crop or pastureland would need to be planted with trees
        • 1/3 of current cropland
        • Source: Jackson and Schlesinger, PNAS 2006
    • 19. Tropical Deforestation
      • Emissions for Tropical Deforestation: 1-2 Petagrams (10^15 g/year) – about the same as US fossil fuel emissions
    • 20. There’s More!
      • Albedo – forests may absorb more energy than what they replace
      • Forest management may produce more potent greenhouse gases: NOx, isoprene, negating carbon stores
      • Are the forest stores permanent?
      • Ecological effects of afforesting prior non-forested land – lower water yield
    • 21. Carbon Markets - Kyoto Regulated
      • Afforestation (no forest for 50 years) or reforestation (forested but cleared before 1990)
        • Demonstrate additionality
        • Demonstrate no leakage
      • Only 1% of portfolio
      • High costs, uncertain future, high complexity in science, legal, and business.
      • Protection of existing forests does not count.
    • 22. Carbon Markets - Voluntary
      • Currently the Chicago Climate Exchange and Private Sales and Registries
      • Current price is ~$1.65/ton CO 2 ($6/ton C) on the CCS
      • Private Markets are $3-$20 ton CO 2
      • Key is ‘Additionality’
      • Currently allowed by CCX:
        • Afforestation (plant trees where none are)
        • Biomass Fuels
        • Soil C sequestration (Agriculture)
      • No Universal Standards – ‘Wild West’
    • 23. http://www.becomeafriend.org/carbon/report.php#capitalfund National Forest Foundation
    • 24. The Good
      • Keeping forests as forests, particularly in the tropics (monitoring, paying for; do we need additionality?)
      • Afforestation of previously forested lands (leakage issues…) – tree planting in the Hayman.
      • Forest fuel offsets fossil fuel combustion (transportation, logging costs).
      • Forest management – decreasing outputs with longer rotations or less intensive harvest (Increase disturbance loss?)
    • 25. The Bad-or at least very uncertain (for Carbon)
      • Treatments to avoid fire emissions – Fire losses are 1-3%/yr; thinning removes 50% of biomass
      • Leakage (development or deforestation occurs on other land)
      • Intensive, short rotation forest management
        • Intensive management uses C and emits NOx
    • 26. The Ugly
      • Coal mining – Carbon Credits for Reforesting Land Strip-Mined for Coal
      Vivian Stockman, Ohio Valley Environmental Coalition
    • 27. Take Home
      • We understand forest C cycle at stand and landscape scale.
      • Moving beyond simple applications gets very complicated quickly.
      • Need to be honest about accounting for public to gain trust.
      • Need to consider time.
      • Retaining forests (including regeneration after disturbance), biomass fuels, and afforestation where forests were historically are best options
