  1. Moving “Beyond The Label” May Lead To Wider Applications Of Uneven-aged Management (alternative silviculture) Klaus Puettmann Edmund Hayes Professor in Silviculture Alternatives

  2. Opportunities for alternative silviculture Lindenmayer et al. 2012 ConsLet

  3. Gobal distribution of “primary designated functions”

  4. Global Scale of Alternatives Natural Disturbance-based management Nature oriented Continuous cover Close-to- nature Ecological forestry Systemic Silviculture Ecosystem management Reduced Impact logging Retention forestry Variable retention World map by www.freeworldmaps.net

  5. Five Principles of Alternative Silviculture

  6. Hurdles to Overcome • Ecology • Economics • Logistics • Education (Information) • Culture (History)

  7. Partial Harvest - Retention • Ecological • Scale - natural disturbances • Economics • Penalty for large tree size • Interest rate • Logistics • Labor (marking trees) • Machines • Education • Culture • “Imprinting” or “knowledge lock-in”

  8. Small-scaleVariability • Ecology • Fire ladder • Diseases • Economics • Wood quality/branch size • Logistics • Machines • Inventory/planning • Education • Culture • Stand layout

  9. Avoid Intensive Operations • Ecology • Competitive understory • Tree quality and stability • Economics • Yield/quality reduction • Logistics • Education • Information about • natural development • Culture

  10. Natural Regeneration • Ecology • Species mixture • Assisted migration • Economics • Variable success • Logistics • Monitoring • Education • Information about establishment • and growth, release potential • Culture • Reforestation laws

  11. Mixed Species • Ecology • Response to disturbances • Economics • Wood value • Logistics • Market access • Education • Competitive relationships • Culture • Reforestation laws

  12. Moving “Beyond The Label” • Flexibility to accommodate local conditions • Relative importance of principles • Focus on outcomes • Not necessarily principles or structures • Ecosystem services • “Babysteps” • Benefit of a conceptual, scientific framework (Complex adaptive system?)
