    Minnesota North Woods Carbon Partnership: Cass and Aitkin County Land Departments Case Study Minnesota North Woods Carbon Partnership: Cass and Aitkin County Land Departments Case Study Presentation Transcript

    • John Gunn, Ph.D. Senior Program Leader Manomet Center for Conservation Sciences Brunswick, Maine 26 February 2008 06/08/09 Minnesota North Woods Carbon Partnership: Cass and Aitkin County Land Departments Case Study
    • Project Intent
      • Understand the implications of Forest Carbon Offset Markets for managed forests in Minnesota
      • Create a structure to evaluate forest carbon stocks under existing Forest Carbon Offset Standards
      • Evaluate Potential of Payments for other Ecosystem Services in the North Woods
      • Today – present results for Aitkin and Cass County Land Department Forest Carbon Analysis under the Chicago Climate Exchange (CCX) and Voluntary Carbon Standard (VCS)
    • Carbon offset market landscape
      • Markets & Registries (Regulatory and Voluntary)
      • Standards, Protocols, & Rules
      • Primary Pathways Relevant to North American forest owners:
        • Chicago Climate Exchange (CCX)
        • California Climate Action Registry (CCAR)
        • Voluntary Carbon Standard (VCS)
      06/08/09
    • Basic Elements of the Major Forest Carbon Offset Standards 06/08/09 Standard Baseline Additionality Permanence CCX Base Year =Growth – Harvest 15 years VCS 5-10 Years Prior Practices Permanent CCAR Regulatory Practices Perm. Easement
    •  
    • CCX (a) vs. VCS (b) Additionality =“improved” forest management category
    • Process
      • VCS
        • Derive VCS Baseline (BAU) from ACLD/CCLD Tactical Plans, and harvest and inventory data
        • Work with LDs to determine where opportunities exist for “improved forest management (IFM)” practices
        • Model impacts of management changes on carbon stocks
        • Calculate eligible carbon: Alternate IFM minus BAU residual carbon stocks
    • Process
      • CCX
        • Evaluate growth models and inventory protocols (against CCX requirements) used to generate Baseline data and net growth calculations for CCX scenario
        • Determine eligible CO2e volume (above ground and live below ground net change converted to CO2 equivalent) in forest stands over time
    • “ Improved” Forest Management Options
      • Extended rotation lengths (10-15 years)
        • Increase average stand age on landscape
        • Enhances structural complexity (larger and more debris associated with harvesting)
        • Reduces frequency of harvesting emissions through disturbance
      • Fuels reduction to minimize risk of catastrophic fire
      • Reduced Impact Logging
        • Minimize soil disturbance through shifting more harvests to frozen conditions
        • Minimize damage to residual stand (reduce mortality, maintain vigor)
    • Management Options (cont.)
      • Create Late-Successional/Old-Growth reserves
        • Or reserves with other objectives
      • Increase stand-level retention practices (residual BA)
        • Patches or dispersed live trees (Legacies)
        • Dead standing, CWD
        • Increased riparian buffer widths
      • Reduce acreage of higher intensity silvicultural practices
    •  
    •  
    • FVS Carbon Module
      • Carbon Submodel of the Fire and Fuels Extension
      • Lake States Variant (individual tree model) – approved by CCX
      • CSA GIS Inventory Data from CCLD and ACLD (used subset of 30% of total acreage in models)
      • Uses accepted forest carbon assumptions (Smith et al. 2006, Jenkins et al. 2003)
    • FVS Fuels and Fire Extension – Carbon Submodel
      • Stand Carbon Stocks are calculated and reported for:
        • Total aboveground live C
        • Belowground live C
        • Standing Dead C
        • Down Dead C
        • Forest Floor C
        • Herbs and Shrubs C
        • Total Removed C
      • Disposition of Carbon in Harvested Wood Products
    • Eligible Pools 06/08/09 Category Carbon Pool Above Ground: Living Tree biomass Shrubs and Herbaceous Understory Above Ground: Dead Standing Dead Coarse and Fine Woody Material Litter Below Ground Soil organic Live Roots Off-site Wood Products
    • Mean Net Annual Change: ACLD = -63,717 MTC CCLD = -97,052 MTC
      • Summary of Annual Residual Live Carbon (aboveground and belowground) in BAU vs. Alternate (ALT) Harvest Scenarios
      6,685 (~1.5 MTC/ac./year) 51,947 45,262 CCLD 6,169 (~1.6 MTC/ac./year) 50,016 43,846 ACLD VCS Eligible Carbon ALT – BAU (MTC) ALT Residual Live Carbon Biomass (MTC) BAU Residual Live Carbon Biomass (MTC) County
    • Eligible Carbon Summary NOTE: 1 MT Carbon =3.667 MTCO2 equivalent (MTCO2e) Source: US EPA $90,496 - $135,744 $98,064 – $147,096 ACLD Potential Revenue (annual) $4.00 - $6.00/ MTCO2e 6,169 MTC – or 22,624 MTCO2e NA -63,717 MTC or -233,650 MTCO2e ACLD 6,685 MTC – or 24,516 MTCO2e NA -97,052 MTC or -355,889 MTCO2e CCLD ACLD Eligible MTCO2e (annual) CCX Potential Revenue (annual) $2.00/ MTCO2e CCX Eligible MTCO2e (annual) County
    • Notes on Results - CCX
      • Area Regulation (harvest target acres instead of target volume) for Desired Future Condition perhaps not suited for Base Year approach
      • Once age classes become more regulated, might be more opportunities for credit
    • Notes on Results - VCS
      • Impact of modifying Residual Basal Area was minimal
      • The harvest intensity shift was conservative – but we now have a spreadsheet calculator tool to evaluate other scenarios
      • Carbon stocks within expected range (e.g., Smith et al. 2006)
      • ACLD and CCLD already practicing FSC-certified management – not much room to alter current practices
      • VCS is considering standards-based methodologies for IFM
    • Next Steps
      • Evaluate Product Fate and Economic Impacts of Forgone Harvest
      • Refine Harvest Intensity Carbon Calculator for broader use
      • Final Report to discuss:
        • Leakage
        • Permanence Implications
        • Peatland Conservation Carbon Implications
        • Ecosystem Services Scoping (e.g., water, recreation)
