  1. Allocation Effects on Sustainability within a Solid Wood Chain A Case Study in South Scotland Stefania Pizzirani and Barry Gardiner, John Fonweban and Stephen Bathgate Forest Research Scotland www.eforwood.com

  2. Ways to Allocate Cut using Business As Usual practices (eg—wood products based on stem diameter) 3. Cut using Stand Level Allocation to achieve both the optimal range of products per tree and to satisfy market demand 2. Cut using Forest Level Allocation to meet consumer demand (eg—biofuel industry)

  3. Business as usual Biomass: Diam <14cm at 6m Pallet: Diam 14-18cm at 6m Red sawlog: Diam >18cm at 6m Straightness <3 Green sawlog: Diam >18cm at 6m Straightness ≥ 3 Green sawlog Red sawlog www.eforwood.com

  4. Stem Straightness Scoring • System developed for use in Sitka spruce • Can be used to predict out-turn of “green” logs

  5. Stem Stiffness Scoring Tree level - ST300 Log level - HM200 www.eforwood.com

  6. Stem Straightness and Stiffness Models www.eforwood.com

  8. Case Study in Southern Scotland www.eforwood.com

  9. Time period of 30 years from 2005 119 ha in forest stand 3694 m3 removed from thinnings 68349 m3 removed from final fellings 72043 total m3 removed 2782 trips to sawmills by 44 tonne trucks Assumed values: £35/m3 green sawlog, £30/m3 red sawlog, £25/m3 pallet, £20/tonne biofuel Case Study in Southern Scotland www.eforwood.com

  10. Processing Plants www.eforwood.com

  11. Scenario 1 Business as Usual - 100% of sawlogs to Dumfries where 80% is Green log and 20% is re-allocated as Red log to Kirriemuir - 100% Red logs to Kirriemuir - 100% of Pallet to Lockerbie - Remainder as Biofuel to EON Lockerbie www.eforwood.com

  12. Scenario 2 Forest Level Allocation Biofuel - 100% of forest allocated as Biofuel to EON Lockerbie www.eforwood.com

  13. Scenario 3 Forest Level Allocation Pallet - All logs allocated as Pallet to Lockerbie - Remainder as Biofuel to EON Lockerbie www.eforwood.com

  14. Scenario 4 Forest Level Allocation Sawlog - 100% of sawlogs to Dumfries where 80% is Green log and 20% is re-allocated as Red log to Kirriemuir - 100% Red logs to Kirriemuir - Remainder as Biofuel to EON Lockerbie www.eforwood.com

  15. Scenario 5 Stand Level Allocation - 100% of Green logs to Dumfries - 100% of Red logs to Kirriemuir - 100% of Pallet to Lockerbie - 100% of Biofuel to EON Lockerbie www.eforwood.com

  16. Craik Wind Risk

  17. Craik Straightness

  18. Indicator Results - GVA

  19. Indicator Results – Employment

  20. Indicator Results – Timber Miles

  21. Indicator Results - GHG

  22. Conclusions • Results depend on end-user’s priorities • This case study was a examination of how ToSIA might be applied at a stand level • Allows the user to ‘play’ with the data to see how different scenarios may affect the outcome of various indicators • Allocation only of value if price differentials significant • The results are only as good as the input data – room for improvement • Scenarios simplistic – room for refinement www.eforwood.com
