  1. Young Stand Monitoring applied in the Morice TSR R. de Jong CSC Winter Workshop 27 February 2014

  2. Assessment of Mid-rotation Stands Stand Development Monitoring (SDM) Young Stand Monitoring (YSM) To assess TRENDS of young stands relative to TSR assumptions and adjust (FAIB) Management Unit assessment – permanent sample plots established on a grid over the target population • To assess Timber Objective of FRPA (FREP) • To change Legislation if required • To change PRACTICE if required • Stand Level assessment – 10 plots per polygon, summarized per TSA ∆ Leg and Practice ∆ TSR

  3. MoriceYSM Program • Established 2012 • 50 * 0.04ha plots • Grid Based • Unbiased estimate of 15 – 50 year old target population

  4. Objectives • Describe Young Stand Characteristics • Assess Accuracy of Inventory Polygons • Assess Accuracy of Site Index Estimates • Check on TSR Assumptions • Localize MSYTs using YSM data

  5. Describe Stand CharacteristicsComposition

  6. Describe Stand CharacteristicsStructure Stand Table - Live Stock Table - Live

  7. Describe Stand CharacteristicsForest Health Live Dead

  8. Assess Accuracy of Inventory PolysObserved vs. VRI Species Composition

  9. Assess Accuracy of SI EstimatesObserved vs. Provincial Site Prod Tile

  10. Check on TSR AssumptionsTIPSY MSYTs @ each Sample Point

  11. Localize MSYTs with YSM Data

  12. Localize MSYTs with YSM DataSite Index Adjustment • TSR-based SI underestimated compared to ground-based site index. • Action: apply site index adjustment by species

  13. Localize MSYTs with YSM DataSpecies Composition • YSM ground species mix vs. TSR assumptions • Action: Apply YSM species mix by AU

  14. Localize MSYTs with YSM DataForest Health Impact • Worst-case FH scenario assumes all stem rust affected Pine will die at rotation. • Action: Apply incremental OAF1 in Pine dominated regimes

  15. Pine Med AU – Site Index

  16. Pine Med AU – Species mix

  17. Pine Med AU – Forest Health

  18. Pine Med AU – Combined Impact

  19. Morice TSR Scenarios

  20. Summary • YSM to describe young stand population • YSM as a check on TSR assumptions, both current and future stands • YSM to generate localized MSYTs • YSM to support alternative modeling scenarios with measured data (forest health) • Future YSM data to include change (growth / mortality)
