Young Stand Monitoring

applied in the

Morice TSR

R. de Jong

CSC Winter Workshop

27 February 2014


Assessment of mid rotation stands
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


Morice ysm program
MoriceYSM Program

  • Established 2012

  • 50 * 0.04ha plots

  • Grid Based

  • Unbiased estimate of 15 – 50 year old target population


Objectives
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

Check on tsr assumptions tipsy msyts @ each sample point
Check on TSR AssumptionsTIPSY MSYTs @ each Sample Point



Localize msyts with ysm data site index adjustment
Localize MSYTs with YSM DataSite Index Adjustment

  • TSR-based SI underestimated compared to ground-based site index.

  • Action: apply site index adjustment by species


Localize msyts with ysm data species composition
Localize MSYTs with YSM DataSpecies Composition

  • YSM ground species mix vs. TSR assumptions

  • Action: Apply YSM species mix by AU


Localize msyts with ysm data forest health impact
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

Summary
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)
