Hurdles to Overcome • Ecology • Economics • Logistics • Education (Information) • Culture (History)
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”
Small-scaleVariability • Ecology • Fire ladder • Diseases • Economics • Wood quality/branch size • Logistics • Machines • Inventory/planning • Education • Culture • Stand layout
Avoid Intensive Operations • Ecology • Competitive understory • Tree quality and stability • Economics • Yield/quality reduction • Logistics • Education • Information about • natural development • Culture
Natural Regeneration • Ecology • Species mixture • Assisted migration • Economics • Variable success • Logistics • Monitoring • Education • Information about establishment • and growth, release potential • Culture • Reforestation laws
Mixed Species • Ecology • Response to disturbances • Economics • Wood value • Logistics • Market access • Education • Competitive relationships • Culture • Reforestation laws
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?)
